A citizen-based platform reveals the distribution of functional groups inside a large city from the Southern Hemisphere: e-Bird and the urban birds of Santiago (Central Chile) Rev. Chilena Hist. Nat. (IF 2.2) Pub Date : 2018-03-27 Pablo Gutiérrez-Tapia, M. Ignacio Azócar, Sergio A. Castro
BackgroundCurrent knowledge of urban bird ecology and biodiversity relies on evidence from cities of the Northern Hemisphere, while the Southern Hemisphere is underrepresented. Santiago is a large city from South America, located in central Chile, which is both a biodiversity hotspot and an Endemic Bird Area. This work is a synthesis, which aims to provide a diversity account for Santiago, and to describe

A modularity-based approach for identifying biodiversity management units Rev. Chilena Hist. Nat. (IF 2.2) Pub Date : 2018-02-26 Ana Inés Borthagaray, Alvaro Soutullo, Alvar Carranza, Matías Arim
BackgroundTaxon- and/or ecosystem-based definitions of management units typically focus on conspicuous species and physical habitat limits; these definitions implicitly assume that these classification systems are related to the mechanisms that determine biodiversity persistence. However, ecological theory shows that this assumption may not be supported. Herein, we introduce the use of modularity analysis

Protected areas in Chile: are we managing them? Rev. Chilena Hist. Nat. (IF 2.2) Pub Date : 2018-01-30 Ignacio J. Petit, Ana N. Campoy, Maria-Jose Hevia, Carlos F. Gaymer, Francisco A. Squeo
BackgroundHuman population growth since the mid-1900s has been accompanied by an unsustainable use of natural resources and a corresponding impact on terrestrial and marine biota. In response, most states have established protected areas as tools to decrease biodiversity loss, being Chile one of the signatories of international conservation agreements such as the Convention on Biological Diversity

The ecological value of long-term studies of birds and mammals in Central America, South America and Antarctica Rev. Chilena Hist. Nat. (IF 2.2) Pub Date : 2017-09-06 Megan Taig-Johnston, Madeline K. Strom, Kendall Calhoun, Kendra Nowak, Luis A. Ebensperger, Loren Hayes
This review covers long-term ecological studies in Central America, South America, and Antarctica that include at least 10 years of data on both terrestrial and marine mammals as well as birds. Specifically, we compiled long-term research on social systems, population ecology, and community ecology. Long-term research is necessary to understand decadal trends and dynamics that would otherwise go unnoticed

Molecular phylogenetic analyses reveal the importance of taxon sampling in cryptic diversity: Liolaemus nigroviridis and L. monticola (Liolaeminae) as focal species Rev. Chilena Hist. Nat. (IF 2.2) Pub Date : 2017-06-20 Fernando Torres-Pérez, Dusan Boric-Bargetto, Evelyn Rodríguez-Valenzuela, Constanza Escobar, R. Eduardo Palma
BackgroundMitochondrial markers are widely used as a first approach in determining evolutionary relationships among vertebrate taxa at different hierarchical scales. Cytochrome b and cytochrome oxidase I are among the most common markers; they are particularly useful in phylogeography and species delineation studies. Simulation and empirical studies show that increasing the taxon sampling has a clear
