Contribution of conservation genetics in assessing neotropical freshwater fish biodiversity [PDF]
Brazilian Journal of Biology, 2008 Human activities have a considerable impact on hydrographic systems and fish fauna. The present review on conservation genetics of neotropical freshwater fish reveals that DNA analyses have been promoting increased knowledge on the genetic structure of fish species and their response to environmental changes.

Detecting Human Presence and Influence on Neotropical Forests with Remote Sensing
Remote Sensing, 2018 The Amazon, and Neotropical forests, are one of the most important global biomes because of their extent and unique biodiversity, as well as their importance to global climate and as a habitat and resource for humans.

The insular herpetofauna of Mexico: Composition, conservation, and biogeographic patterns
Ecology and Evolution, 2021 We compile a Mexican insular herpetofaunal checklist to estimate endemism, conservation status, island threats, net taxonomic turnover among six biogeographic provinces belonging to the Nearctic and Neotropical regions, and the relationships between ...

Ecography, EarlyView.Studies using climatic gradients play a key role in our understanding of the importance of rainfall and temperature as factors regulating species diversity and distribution, and thus of likely responses to climate change. However, such studies currently consider above‐ground species only, ignoring the diverse hypogaeic (subterranean) invertebrate fauna.

Amazonian amphibian diversity is primarily derived from late Miocene Andean lineages. [PDF]
PLoS Biology, 2009 The Neotropics contains half of remaining rainforests and Earth's largest reservoir of amphibian biodiversity. However, determinants of Neotropical biodiversity (i.e., vicariance, dispersals, extinctions, and radiations) earlier than the Quaternary are ...

Botanical Sciences, 2021 Background: The Neotropical woody bamboos (NWB) comprise a clade native to the Western Hemisphere. Taxonomically the NWB are classified into three subtribes: Arthrostylidiinae, Chusqueinae, and Guaduinae.

Ecography, EarlyView.Spatial sampling bias in occurrence data can generate spurious environmental associations in models of species distributions and ecological niches, and can also undermine inferences based on permutation tests made using these models. Geographic randomization tests are often used to generate distributions of expected behavior under the null hypothesis ...

Ecography, EarlyView.Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

Quaternary paleoclimatology, neotropical biodiversity, and potential effects of global warming.
Contributions to Science, 2007 [CAT] Els canvis climàtics quaternaris enregistrats a l’hemisferi nord també han afectat la regió neotropical i han contribuït a definirne els patrons actuals de biodiversitat. Els estudis moleculars de DNA que s’han dut a terme en espècies neotropicals actuals mostren una acceleració significativa de les taxes d’especiació en els darrers 5 milions d ...
