Prostaglandins (Pgs) are eicosanoid lipid mediators detected in all vertebrates, in some marine invertebrates, macroalgae and in diatoms, a class of eukaryotic microalgae composing the phytoplankton. The enzymes involved in the Pgs pathway were found to be differentially expressed in two strains of the diatom , named FE7 and FE60, already known to produce different levels of oxylipins, a class of secondary

Atlantic bonito (Sarda sarda) genomic analysis reveals population differentiation across Northeast Atlantic and mediterranean locations: Implications for fishery management Mar. Environ. Res. (IF 3.3) Pub Date : 2024-02-13 Judith Ollé-Vilanova, Ghailen Hajjej, David Macias, Sámar Saber, Pedro G. Lino, Rubén Muñoz-Lechuga, Sid'Ahmed Baibbat, Fambaye Ngom Sow, N'guessan Constance Diaha, Rosa M. Araguas, Núria Sanz, Jordi Vinas
The Atlantic bonito (, family Scombridae) is a pelagic species and one of the most exploited small tuna species. Despite its economic importance, biological information is scarce with no associated management directives. In this study, using a population genomic approach resulted in a lack of panmixia of two genetic pools with different effective population sizes (east central-tropical Atlantic and

Assessing sandy beach macrofaunal assemblages across geographically diverse morphodynamic environments Mar. Environ. Res. (IF 3.3) Pub Date : 2024-02-13 M.C. Risoli, M.S. Yusseppone, O. Defeo, B.J. Lomovasky
While the physical characteristics of sandy beaches play a significant role in shaping the macrofaunal community features through morphodynamics, regional environmental factors may also account for deviations from the expected patterns. Here, we assess the concurrent effects of local morphodynamic factors and regional variables, such as sea surface temperature (SST), salinity, and chlorophyll- (chl-)

Understanding baseline levels of physiological stress tolerance from excessive exercise in a holobenthic octopus species, Octopus pallidus Mar. Environ. Res. (IF 3.3) Pub Date : 2024-02-10 Ryan D. Day, Katherine B. Baker, Patricia Peinado, Jayson M. Semmens
Cephalopods receive a great deal of attention due to their socioeconomically important fisheries and aquaculture industries as well their unique biological features. However, basic information about their physiological responses under stress conditions is lacking. This study investigated the impact of a simple stressor, exercise to exhaustion, on the activity levels of antioxidant enzymes and the concentrations

Effects of temperature and nitrogen sources on physiological performance of the coccolithophore Emiliania huxleyi Mar. Environ. Res. (IF 3.3) Pub Date : 2024-02-09 Zihao Wang, Shanying Tong, Dong Xu, Xintong Huang, Yanmin Sun, Bingkun Wang, Haoming Sun, Xiaowen Zhang, Xiao Fan, Wei Wang, Ke Sun, Yitao Wang, Pengyan Zhang, Zhifeng Gu, Naihao Ye
Both temperature and nutrient levels are rising in worldwide ocean ecosystems, and they strongly influence biological responses of phytoplankton. However, few studies have addressed the interactive effects of temperature and nitrogen sources on physiological performance of the coccolithophore In this study, we evaluated algal growth, photosynthesis and respiration, elemental composition, enzyme activity
