Combining transinfected Wolbachia and a genetic sexing strain to control Aedes albopictus in laboratory-controlled conditions Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Sarah Scussel, Benjamin Gaudillat, Jérémy Esnault, Quentin Lejarre, Marianne Duployer, Cyrille Lebon, Aude Benlali, Patrick Mavingui, Pablo Tortosa, Julien Cattel
The global expansion of Aedes albopictus has stimulated the development of environmentally friendly methods aiming to control disease transmission through the suppression of natural vector populations. Sterile male release programmes are currently being deployed worldwide, and are challenged by the availability of an efficient sex separation which can be achieved mechanically at the pupal stage and/or

Social and genetic connectivity despite ecological variation in a killer whale network Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Eve Jourdain, Richard Karoliussen, Sarah L. Fordyce Martin, Øystein Langangen, Todd Robeck, Katrine Borgå, Anders Ruus, Andrew D. Foote
Philopatric kin-based societies encourage a narrow breadth of conservative behaviours owing to individuals primarily learning from close kin, promoting behavioural homogeneity. However, weaker social ties beyond kin, and across a behaviourally diverse social landscape, could be sufficient to induce variation and a greater ecological niche breadth. We investigated a network of 457 photo-identified killer

Social restructuring during harsh environmental conditions promotes cooperative behaviour in a songbird Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Ettore Camerlenghi, Sergio Nolazco, Damien R. Farine, Robert D. Magrath, Anne Peters
Cooperation may emerge from intrinsic factors such as social structure and extrinsic factors such as environmental conditions. Although these factors might reinforce or counteract each other, their interaction remains unexplored in animal populations. Studies on multilevel societies suggest a link between social structure, environmental conditions and individual investment in cooperative behaviours

Unconventional life history in a migratory shorebird: desegregating reproduction and migration Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Colby R. Slezak, Erik J. Blomberg, Amber M. Roth, Liam A. Berigan, Alexander C. Fish, Rachel Darling, Sarah J. Clements, Greg Balkcom, Bobbi Carpenter, Gary Costanzo, Jeffrey Duguay, Clayton L. Graham, William Harvey, Michael Hook, Douglas L. Howell, Seth Maddox, Shawn W. Meyer, Theodore C. Nichols, J. Bruce Pollard, Christian Roy, Joshua C. Stiller, Jacob N. Straub, Mathieu Tetreault, Reina Tyl, Lisa
Conventional life-history theory predicts that energy-demanding events such as reproduction and migration must be temporally segregated to avoid resource limitation. Here, we provide, to our knowledge, the first direct evidence of ‘itinerant breeding’ in a migratory bird, an incredibly rare breeding strategy (less than 0.1% of extant bird species) that involves the temporal overlap of migratory and

Individual variation in life-history timing: synchronous presence, asynchronous events and phenological compensation in a wild mammal Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Roxanne S. Beltran, Raquel R. Lozano, Patricia A. Morris, Patrick W. Robinson, Rachel R. Holser, Theresa R. Keates, Arina B. Favilla, A. Marm Kilpatrick, Daniel P. Costa
Many animals and plants have species-typical annual cycles, but individuals vary in their timing of life-history events. Individual variation in fur replacement (moult) timing is poorly understood in mammals due to the challenge of repeated observations and longitudinal sampling. We examined factors that influence variation in moult duration and timing among elephant seals (Mirounga angustirostris)

Artificial light at night and warming impact grazing rates and gonad index of the sea urchin Centrostephanus rodgersii Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Amelia Caley, Ezequiel M. Marzinelli, Maria Byrne, Mariana Mayer-Pinto
Artificial light at night (ALAN) is a growing threat to coastal habitats, and is likely to exacerbate the impacts of other stressors. Kelp forests are dominant habitats on temperate reefs but are declining due to ocean warming and overgrazing. We tested the independent and interactive effects of ALAN (dark versus ALAN) and warming (ambient versus warm) on grazing rates and gonad index of the sea urchin

The impact of within-host coinfection interactions on between-host parasite transmission dynamics varies with spatial scale Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Shaun P. Keegan, Amy B. Pedersen, Andy Fenton
Within-host interactions among coinfecting parasites can have major consequences for individual infection risk and disease severity. However, the impact of these within-host interactions on between-host parasite transmission, and the spatial scales over which they occur, remain unknown. We developed and apply a novel spatially explicit analysis to parasite infection data from a wild wood mouse (Apodemus

The importance of migratory drop-off for island colonization in birds Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Paul Dufour, Ferran Sayol, Rob Cooke, Tim M. Blackburn, Laure Gallien, Michael Griesser, Manuel J. Steinbauer, Søren Faurby
Seasonal migration is an underappreciated driver of animal diversification. Changes in migratory behaviour may favour the establishment of sedentary founder populations and promote speciation if there is sufficient reproductive isolation between sedentary and migratory populations. From a systematic literature review, we here quantify the role of migratory drop-off—the loss of migratory behaviour—in

Invasibility of a North American soil ecosystem to amphibian-killing fungal pathogens Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Sarah E. McGrath-Blaser, Natalie McGathey, Allison Pardon, Arik M. Hartmann, Ana V. Longo
North American salamanders are threatened by intercontinental spread of chytridiomycosis, a deadly disease caused by the fungal pathogen Batrachochytrium salamandrivorans (Bsal). To predict potential dispersal of Bsal spores to salamander habitats, we evaluated the capacity of soil microbial communities to resist invasion. We determined the degree of habitat invasibility using soils from five locations

Inferring the evolution of reproductive isolation in a lineage of fossil threespine stickleback, Gasterosteus doryssus Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Raheyma Siddiqui, Samantha Swank, Allison Ozark, Franklin Joaquin, Matthew P. Travis, Caleb D. McMahan, Michael A. Bell, Yoel E. Stuart
Darwin attributed the absence of species transitions in the fossil record to his hypothesis that speciation occurs within isolated habitat patches too geographically restricted to be captured by fossil sequences. Mayr's peripatric speciation model added that such speciation would be rapid, further explaining missing evidence of diversification. Indeed, Eldredge and Gould's original punctuated equilibrium

Mechanistic interactions as the origin of modularity in biological networks Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Daniel Wechsler, Jordi Bascompte
Biological networks are often modular. Explanations for this peculiarity either assume an adaptive advantage of a modular design such as higher robustness, or attribute it to neutral factors such as constraints underlying network assembly. Interestingly, most insights on the origin of modularity stem from models in which interactions are either determined by highly simplistic mechanisms, or have no

Association between the gut microbiome and carotenoid plumage phenotype in an avian hybrid zone Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Marcella D. Baiz, Andrew W. Wood, David P. L. Toews
Vertebrates host complex microbiomes that impact their physiology. In many taxa, including colourful wood-warblers, gut microbiome similarity decreases with evolutionary distance. This may suggest that as host populations diverge, so do their microbiomes, because of either tight coevolutionary dynamics, or differential environmental influences, or both. Hybridization is common in wood-warblers, but

Vertically inherited microbiota and environment modifying behaviours conceal genetic variation in dung beetle life history Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Patrick T. Rohner, Armin P. Moczek
Diverse organisms actively manipulate their (sym)biotic and physical environment in ways that feed back on their own development. However, the degree to which these processes affect microevolution remains poorly understood. The gazelle dung beetle both physically modifies its ontogenetic environment and structures its biotic interactions through vertical symbiont transmission. By experimentally eliminating

Small skeletons show size-specific scaling: an exploration of allometry in the mammalian lumbar spine Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 S. M. Smith, L. R. Heaney, K. D. Angielczyk
Studies of vertebrate bone biomechanics often focus on skeletal adaptations at upper extremes of body mass, disregarding the importance of skeletal adaptations at lower extremes. Yet mammals are ancestrally small and most modern species have masses under 5 kg, so the evolution of morphology and function at small size should be prioritized for understanding how mammals subsist. We examined allometric

A shared pattern of midfacial bone modelling in hominids suggests deep evolutionary roots for human facial morphogenesis Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-17 Alexandra Schuh, Yann Heuzé, Philipp Gunz, Michael A. Berthaume, Colin N. Shaw, Jean-Jacques Hublin, Sarah Freidline
Midfacial morphology varies between hominoids, in particular between great apes and humans for which the face is small and retracted. The underlying developmental processes for these morphological differences are still largely unknown. Here, we investigate the cellular mechanism of maxillary development (bone modelling, BM), and how potential changes in this process may have shaped facial evolution

Resolving selfish and spiteful interdependent conflict Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Alexander J. Stewart, Charlie Pilgrim, Nichola J. Raihani
Interdependence occurs when individuals have a stake in the success or failure of others, such that the outcomes experienced by one individual also generate costs or benefits for others. Discussion on this topic has typically focused on positive interdependence (where gains for one individual result in gains for another) and on the consequences for cooperation. However, interdependence can also be

Blessing or curse: how the epigenetic resolution of host-transposable element conflicts shapes their evolutionary dynamics Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Yuheng Huang, Yuh Chwen G. Lee
Transposable elements (TEs) are selfish genetic elements whose antagonistic interactions with hosts represent a common genetic conflict in eukaryotes. To resolve this conflict, hosts have widely adopted epigenetic silencing that deposits repressive marks at TEs. However, this mechanism is imperfect and fails to fully halt TE replication. Furthermore, TE epigenetic silencing can inadvertently spread

Spillover effects from invasive Acacia alter the plant–pollinator networks and seed production of native plants Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Maisie F. Brett, Paula Strauss, Kurt van Wyk, Ian P. Vaughan, Jane Memmott
Invasive flowering plants can disrupt plant–pollinator networks. This is well documented where invasives occur amongst native plants; however, the potential for ‘spillover’ effects of invasives that form stands in adjacent habitats are less well understood. Here we quantify the impact of two invasive Australian species, Acacia saligna and Acacia longifolia, on the plant–pollinator networks in fynbos

Leaf gene expression trajectories during the growing season are consistent between sites and years in American beech Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 U. Uzay Sezen, Jessica E. Shue, Samantha J. Worthy, Stuart J. Davies, Sean M. McMahon, Nathan G. Swenson
Transcriptomics provides a versatile tool for ecological monitoring. Here, through genome-guided profiling of transcripts mapping to 33 042 gene models, expression differences can be discerned among multi-year and seasonal leaf samples collected from American beech trees at two latitudinally separated sites. Despite a bottleneck due to post-Columbian deforestation, the single nucleotide polymorphism-based

Chemical species recognition in an adaptive radiation of Hawaiian Tetragnatha spiders (Araneae: Tetragnathidae) Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Seira A. Adams, Anjali Gurajapu, Albert Qiang, Moritz Gerbaulet, Stefan Schulz, Neil D. Tsutsui, Santiago R. Ramirez, Rosemary G. Gillespie
Studies of adaptive radiations have played a central role in our understanding of reproductive isolation. Yet the focus has been on human-biased visual and auditory signals, leaving gaps in our knowledge of other modalities. To date, studies on chemical signals in adaptive radiations have focused on systems with multimodal signalling, making it difficult to isolate the role chemicals play in reproductive

Parallel evolution despite low genetic diversity in three-spined sticklebacks Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Carla Coll-Costa, Carolin Dahms, Petri Kemppainen, Carlos M. Alexandre, Filipe Ribeiro, Davor Zanella, Linda Zanella, Juha Merilä, Paolo Momigliano
When populations repeatedly adapt to similar environments they can evolve similar phenotypes based on shared genetic mechanisms (parallel evolution). The likelihood of parallel evolution is affected by demographic history, as it depends on the standing genetic variation of the source population. The three-spined stickleback (Gasterosteus aculeatus) repeatedly colonized and adapted to brackish and freshwater

New occurrences of the bone-eating worm Osedax from Late Cretaceous marine reptiles and implications for its biogeography and diversification Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Sarah Jamison-Todd, Philip D. Mannion, Adrian G. Glover, Paul Upchurch
The bone-eating worm Osedax is a speciose and globally distributed clade, primarily found on whale carcasses in marine environments. The earliest fossil evidence for Osedax borings was previously described in plesiosaur and sea turtle bones from the mid-Cretaceous of the United Kingdom, representing the only unequivocal pre-Oligocene occurrences. Confirming through CT scanning, we present new evidence

The influence of the land-to-sea macroevolutionary transition on vertebral column disparification in Pinnipedia Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-10 Juan Miguel Esteban, Alberto Martín-Serra, Alejandro Pérez-Ramos, Natalia Rybczynski, Katrina Jones, Borja Figueirido
The repeated returns of vertebrates to the marine ecosystems since the Triassic serve as an evolutionary model to understand macroevolutionary change. Here we investigate the effects of the land-to-sea transition on disparity and constraint of the vertebral column in aquatic carnivorans (Carnivora; Pinnipedia) to assess how their functional diversity and evolutionary innovations influenced major radiations

Language-like efficiency and structure in house finch song Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Mason Youngblood
Communication needs to be complex enough to be functional while minimizing learning and production costs. Recent work suggests that the vocalizations and gestures of some songbirds, cetaceans and great apes may conform to linguistic laws that reflect this trade-off between efficiency and complexity. In studies of non-human communication, though, clustering signals into types cannot be done a priori

Spatial versus spatio-temporal approaches for studying metacommunities: a multi-taxon analysis in Mediterranean and tropical temporary ponds Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Ángel Gálvez, Pedro R. Peres-Neto, Andreu Castillo-Escrivà, Fabián Bonilla, Antonio Camacho, Eduardo M. García-Roger, Sanda Iepure, Javier Miralles, Juan S. Monrós, Carla Olmo, Antonio Picazo, Carmen Rojo, Juan Rueda, Mahmood Sasa, Mati Segura, Xavier Armengol, Francesc Mesquita-Joanes
Prior research on metacommunities has largely focused on snapshot surveys, often overlooking temporal dynamics. In this study, our aim was to compare the insights obtained from metacommunity analyses based on a spatial approach repeated over time, with a spatio-temporal approach that consolidates all data into a single model. We empirically assessed the influence of temporal variation in the environment

Body mass mediates spatio-temporal responses of mammals to human frequentation across Italian protected areas Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Marco Salvatori, Ilaria Greco, Luca Petroni, Alessandro Massolo, Enrico Dorigatti, Martina Miscioscia, Luca Natucci, Valentina Oberosler, Piergiovanni Partel, Paolo Pedrini, Gilberto Volcan, Francesco Rovero
Protected area (PA) networks are a pivotal tool to fight biodiversity loss, yet they often need to balance the mission of nature conservation with the socio-economic need of giving opportunity for outdoor recreation. Recreation in natural areas is important for human health in an urbanized society, but can prompt behavioural modifications in wild animals. Rarely, however, have these responses being

No correlative evidence of costs of infection or immunity on leucocyte telomere length in a wild population of Soay sheep Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Sanjana Ravindran, Sarah L. Underwood, Jennifer Dorrens, Luise A. Seeker, Kathryn Watt, Rachael V. Wilbourn, Alexandra M. Sparks, Rona Sinclair, Zhulin Chen, Jill G. Pilkington, Tom N. McNeilly, Lea Harrington, Josephine M. Pemberton, Daniel H. Nussey, Hannah Froy
Telomere length (TL) is a biomarker hypothesized to capture evolutionarily and ecologically important physiological costs of reproduction, infection and immunity. Few studies have estimated the relationships among infection status, immunity, TL and fitness in natural systems. The hypothesis that short telomeres predict reduced survival because they reflect costly consequences of infection and immune

Ecosystem effects of intraspecific variation in a colour polymorphic amphibian Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Sean T. Giery, Reese K. Sloan, James Watson, Autumn Groesbeck, Jon M. Davenport
An emerging consensus suggests that evolved intraspecific variation can be ecologically important. However, evidence that evolved trait variation within vertebrates can influence fundamental ecosystem-level processes remains sparse. In this study, we sought to assess the potential for evolved variation in the spotted salamander (Ambystoma maculatum) to affect aquatic ecosystem properties. Spotted salamanders

Olfactory self-recognition in two species of snake Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Troy Freiburger, Noam Miller, Morgan Skinner
Mark tests, in which an animal uses a mirror to locate and examine an otherwise unnoticeable mark on its own body, are commonly used to assess self-recognition, which may have implications for self-awareness. Recently, several olfactory-reliant species have appeared to pass odour-based versions of the mark test, though it has never been attempted in reptiles. We conducted an odour-based mark test on

Group mating in Cretaceous water striders Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-04-03 Yanzhe Fu, Chenyang Cai, Pingping Chen, Qiang Xuan, Tin Aung Myint, Diying Huang
Fossilized mating insects are irreplaceable material for comprehending the evolution of the mating behaviours and life-history traits in the deep-time record of insects as well as the potential sexual conflict. However, cases of mating pairs are particularly rare in fossil insects, especially aquatic or semi-aquatic species. Here, we report the first fossil record of a group of water striders in copulation

Synergistic negative effects between a fungicide and high temperatures on homing behaviours in honeybees Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Nicole S. DesJardins, Elise K. Chester, Cahit Ozturk, Colin M. Lynch, Jon F. Harrison, Brian H. Smith
Interactions between environmental stressors may contribute to ongoing pollinator declines, but have not been extensively studied. Here, we examined the interaction between the agricultural fungicide Pristine (active ingredients: 25.2% boscalid, 12.8% pyraclostrobin) and high temperatures on critical honeybee behaviours. We have previously shown that consumption of field-realistic levels of this fungicide

Personality heterophily and friendship as drivers for successful cooperation Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Debottam Bhattacharjee, Sophie Waasdorp, Esmee Middelburg, Elisabeth H.M. Sterck, Jorg J. M. Massen
Cooperation is widespread and arguably a pivotal evolutionary force in maintaining animal societies. Yet, proximately, what underlying motivators drive individuals to cooperate remains relatively unclear. Since ‘free-riders’ can exploit the benefits by cheating, selecting the right partner is paramount. Such decision rules need not be based on complex calculations and can be driven by cognitively less-demanding

Different currencies for calculating resource phenology result in opposite inferences about trophic mismatches Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Tom S. L. Versluijs, Mikhail K. Zhemchuzhnikov, Dmitry Kutcherov, Tomas Roslin, Niels Martin Schmidt, Jan A. van Gils, Jeroen Reneerkens
Shifts in phenology are among the key responses of organisms to climate change. When rates of phenological change differ between interacting species they may result in phenological asynchrony. Studies have found conflicting patterns concerning the direction and magnitude of changes in synchrony, which have been attributed to biological factors. A hitherto overlooked additional explanation are differences

A sex-linked supergene with large effects on sperm traits has little impact on reproductive traits in female zebra finches Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Katherine Assersohn, Oscar Morton, Jon Slate, Nicola Hemmings
Despite constituting an essential component of fitness, reproductive success can vary remarkably between individuals and the causes of such variation are not well understood across taxa. In the zebra finch—a model songbird, almost all the variation in sperm morphology and swimming speed is maintained by a large polymorphic inversion (commonly known as a supergene) on the Z chromosome. The relationship

Parasite escape mechanisms drive morphological diversification in avian lice Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Stanislav Kolencik, Edward L. Stanley, Aswaj Punnath, Avery R. Grant, Jorge Doña, Kevin P. Johnson, Julie M. Allen
Organisms that have repeatedly evolved similar morphologies owing to the same selective pressures provide excellent cases in which to examine specific morphological changes and their relevance to the ecology and evolution of taxa. Hosts of permanent parasites act as an independent evolutionary experiment, as parasites on these hosts are thought to be undergoing similar selective pressures. Parasitic

Synergistic response to climate stressors in coral is associated with genotypic variation in baseline expression Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Jenna Dilworth, Wyatt C. Million, Maria Ruggeri, Emily R. Hall, Ashley M. Dungan, Erinn M. Muller, Carly D. Kenkel
As environments are rapidly reshaped due to climate change, phenotypic plasticity plays an important role in the ability of organisms to persist and is considered an especially important acclimatization mechanism for long-lived sessile organisms such as reef-building corals. Often, this ability of a single genotype to display multiple phenotypes depending on the environment is modulated by changes

The three-dimensionally articulated oral apparatus of a Devonian heterostracan sheds light on feeding in Palaeozoic jawless fishes Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-27 Richard P. Dearden, Andy S. Jones, Sam Giles, Agnese Lanzetti, Madleen Grohganz, Zerina Johanson, Stephan Lautenschlager, Emma Randle, Philip C. J. Donoghue, Ivan J. Sansom
Attempts to explain the origin and diversification of vertebrates have commonly invoked the evolution of feeding ecology, contrasting the passive suspension feeding of invertebrate chordates and larval lampreys with active predation in living jawed vertebrates. Of the extinct jawless vertebrates that phylogenetically intercalate these living groups, the feeding apparatus is well-preserved only in the

Dung beetles increase plant growth: a meta-analysis Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-20 Daniel J. Anderson, Jacob D. Berson, Raphael K. Didham, Leigh W. Simmons, Theodore A. Evans
The ecosystem services provided by dung beetles are well known and valued. Dung beetles bury dung for feeding and breeding, and it is generally thought that the process of burying dung increases nutrient uptake by plant roots, which promotes plant growth. Many studies have tested the effects of dung beetles on plant growth, but there has been no quantitative synthesis of these studies. Here we use

Congruity of genomic and epidemiological data in modelling of local cholera outbreaks Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-20 Mateusz Wilinski, Lauren Castro, Jeffrey Keithley, Carrie Manore, Josefina Campos, Ethan Romero-Severson, Daryl Domman, Andrey Y. Lokhov
Cholera continues to be a global health threat. Understanding how cholera spreads between locations is fundamental to the rational, evidence-based design of intervention and control efforts. Traditionally, cholera transmission models have used cholera case-count data. More recently, whole-genome sequence data have qualitatively described cholera transmission. Integrating these data streams may provide

No evidence for a role of MHC class II genotype in the chemical encoding of heterozygosity and relatedness in Antarctic fur seals Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-20 Jonas Tebbe, Katja Havenstein, Jaume Forcada, Ralph Tiedemann, Barbara Caspers, Joseph I. Hoffman
Despite decades of research, surprisingly little is known about the mechanism(s) by which an individual's genotype is encoded in odour. Many studies have focused on the role of the major histocompatibility complex (MHC) owing to its importance for survival and mate choice. However, the salience of MHC-mediated odours compared to chemicals influenced by the rest of the genome remains unclear, especially

Single and combined exposure to ‘bee safe’ pesticides alter behaviour and offspring production in a ground-nesting solitary bee (Xenoglossa pruinosa) Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-20 Sabrina Rondeau, Nigel E. Raine
Mounting evidence supporting the negative impacts of exposure to neonicotinoids on bees has prompted the registration of novel ‘bee-friendly’ insecticides for agricultural use. Flupyradifurone (FPF) is a butenolide insecticide that shares the same mode of action as neonicotinoids and has been assessed to be ‘practically non-toxic to adult honeybees' using current risk assessment procedures. However

Biomechanical adaptations enable phoretic mite species to occupy distinct spatial niches on host burying beetles Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-20 Syuan-Jyun Sun, Simon Chen, Walter Federle, Rebecca M. Kilner
Niche theory predicts that ecologically similar species coexist by minimizing interspecific competition through niche partitioning. Therefore, understanding the mechanisms of niche partitioning is essential for predicting interactions and coexistence between competing organisms. Here, we study two phoretic mite species, Poecilochirus carabi and Macrocheles nataliae that coexist on the same host burying

Behavioural consequences of intraspecific variability in a mate recognition signal Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-06 Maximilian Steurer, Joachim Ruther, Tamara Pokorny
Mate recognition is paramount for sexually reproducing animals, and many insects rely on cuticular hydrocarbons (CHCs) for close-range sexual communication. To ensure reliable mate recognition, intraspecific sex pheromone variability should be low. However, CHCs can be influenced by several factors, with the resulting variability potentially impacting sexual communication. While intraspecific CHC variability

Predators control pests and increase yield across crop types and climates: a meta-analysis Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-06 Gabriel X. Boldorini, Matthew A. Mccary, Gustavo Q. Romero, Kirby L. Mills, Nathan J. Sanders, Peter B. Reich, Radek Michalko, Thiago Gonçalves-Souza
Pesticides have well-documented negative consequences to control crop pests, and natural predators are alternatives and can provide an ecosystem service as biological control agents. However, there remains considerable uncertainty regarding whether such biological control can be a widely applicable solution, especially given ongoing climatic variation and climate change. Here, we performed a meta-analysis

Early-acting inbreeding depression can evolve as an inbreeding avoidance mechanism Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-06 Yaniv Brandvain, Lia Thomson, Tanja Pyhäjärvi
Despite the potential for mechanical, developmental and/or chemical mechanisms to prevent self-fertilization, incidental self-fertilization is inevitable in many predominantly outcrossing species. In such cases, inbreeding can compromise individual fitness. Unquestionably, much of this inbreeding depression is maladaptive. However, we show that when reproductive compensation allows for the replacement

Integration of genomic and ecological methods inform management of an undescribed, yet highly exploited, sardine species Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2024-03-06 Jéssica Fernanda Ramos Coelho, Liana de Figueiredo Mendes, Fabio Di Dario, Pedro Hollanda Carvalho, Ricardo Marques Dias, Sergio Maia Queiroz Lima, Julia Tovar Verba, Ricardo J. Pereira
Assessing genetic diversity within species is key for conservation strategies in the context of human-induced biotic changes. This is important in marine systems, where many species remain undescribed while being overfished, and conflicts between resource-users and conservation agencies are common. Combining niche modelling with population genomics can contribute to resolving those conflicts by identifying

Leveraging big data to uncover the eco-evolutionary factors shaping behavioural development Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Sean M. Ehlman, Ulrike Scherer, David Bierbach, Fritz Francisco, Kate L. Laskowski, Jens Krause, Max Wolf
Mapping the eco-evolutionary factors shaping the development of animals’ behavioural phenotypes remains a great challenge. Recent advances in ‘big behavioural data’ research—the high-resolution tracking of individuals and the harnessing of that data with powerful analytical tools—have vastly improved our ability to measure and model developing behavioural phenotypes. Applied to the study of behavioural

Who will name new plant species? Temporal change in the origins of taxonomists in China Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Jiajia Liu, Xiaofeng Jin, Shenhao Yao, Yuan Wang, Yifei Lu, Qianyu Chen, Chuping Wu, Ferry Slik, David Lindenmayer
Discovery rates of new plant species need to be accelerated because many species will be extinct before they are formally described. Current studies have focused on where new species may occur and their characteristics. However, who will actually discover and describe these new species has received limited attention. Here, we used 31 576 vascular plant species distributed and described in China as

By a whisker: the sensory role of vibrissae in hovering flight in nectarivorous bats Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Eran Amichai, David B. Boerma, Rachel A. Page, Sharon M. Swartz, Hannah M. ter Hofstede
Whiskers are important tactile structures widely used across mammals for a variety of sensory functions, but it is not known how bats—representing about a fifth of all extant mammal species—use them. Nectar-eating bats typically have long vibrissae (long, stiff hairs) arranged in a forward-facing brush-like formation that is not present in most non-nectarivorous bats. They also commonly use a unique

Local infectious disease experience influences vaccine refusal rates: a natural experiment Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Konstantinos Angelopoulos, Gillian Stewart, Rebecca Mancy
Vaccination has been critical to the decline in infectious disease prevalence in recent centuries. Nonetheless, vaccine refusal has increased in recent years, with complacency associated with reductions in disease prevalence highlighted as an important contributor. We exploit a natural experiment in Glasgow at the beginning of the twentieth century to investigate whether prior local experience of an

A 17-year time-series of fungal environmental DNA from a coastal marine ecosystem reveals long-term seasonal-scale and inter-annual diversity patterns Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Nathan Chrismas, Ro Allen, Michael J. Allen, Kimberley Bird, Michael Cunliffe
Changing patterns in diversity are a feature of many habitats, with seasonality a major driver of ecosystem structure and function. In coastal marine plankton-based ecosystems, seasonality has been established through long-term time-series of bacterioplankton and protists. Alongside these groups, fungi also inhabit coastal marine ecosystems. If and how marine fungi show long-term intra- and inter-annual

Discrepancies between the drivers of alpha and beta plant diversity in arable field margins Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Sébastien Boinot, Audrey Alignier
Field margins are major habitats for biodiversity conservation and ecosystem functioning in agricultural landscapes, but biotic homogenization of plant communities threatens their ecological and agronomic functions. Our objective is to determine the drivers of plant diversity in field margins for conservation and restoration purposes. To do so, we assessed the effects of field margin structure and

Temperature and nutrients drive eco-phenotypic dynamics in a microbial food web Proc. Royal Soc. B: Biol. Sci. (IF 4.7) Pub Date : 2023-02-01 Ze-Yi Han, Daniel J. Wieczynski, Andrea Yammine, Jean P. Gibert
Anthropogenic increases in temperature and nutrient loads will likely impact food web structure and stability. Although their independent effects have been reasonably well studied, their joint effects—particularly on coupled ecological and phenotypic dynamics—remain poorly understood. Here we experimentally manipulated temperature and nutrient levels in microbial food webs and used time-series analysis
