Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests

open access: yesEcology, Volume 107, Issue 3, March 2026.
Abstract Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change.

Predicting the potential distribution of the Endangered huemul deer Hippocamelus bisulcus in North Patagonia [PDF]

open access: yes, 2016
Habitat loss is one of the main threats to wildlife, particularly large mammals. Estimating the potential distribution of threatened species to guide surveys and conservation is crucial, primarily because such species tend to exist in small fragmented ...

Question the Mark: A Review and Assessment of Bat Marking Practices

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

Response of Bird Populations to Long-term Changes in Local Vegetation and Regional Forest Cover [PDF]

open access: yes, 2016
We analyzed data from a woodland site for a 59-year period to determine whether changes in bird populations are related to changes in the diversity and relative abundance of woody plant species even when vegetation structure, degree of forest ...

Phylogenomics of Anthomyiidae and a revised classification of Scathophagidae (Diptera: Calyptratae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Family Anthomyiidae is revised using a broad sampling of genera, including the Neotropical Coenosopsia and Phaonantho, which are recovered as Coenosopsiinae Bailey & Michelsen (subfam. nov.). The former family Scathophagidae is recovered within the family Anthomyiidae with strong support and relegated to subfamily rank as Scathophaginae (stat.

[Phylogenetic relationships among Neotropical deer genera (Artiodactyla: Cervidae) by means of DNAmt sequences and microsatellite markers].

open access: yesRevista de biologia tropical, 2009
The current work shows two molecular phylogenetic analyses on Neotropical deers. In the first analysis, the mitochondrial control region (D-loop) was sequenced in six Odocoileinae species from Latin America, using the sequences of two Muntiacinae as outgroups.

Cascading Effects of Overhunting on the Functional Tree Composition of Amazonian Forests

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We examined how overhunting‐induced defaunation affects the functional composition of tropical tree communities in western Brazilian Amazonia. Using a robust, spatially replicated dataset from 30 forest plots across a well‐defined gradient of hunting pressure, we assessed the impacts of vertebrate depletion on plant recruitment patterns, dispersal ...

Optimizing fecal DNA collection and storage techniques for noninvasive genetic sampling of river otters

open access: yesWildlife Society Bulletin, Volume 49, Issue 4, December 2025.
This study compared 2 non‐invasive DNA collection methods for river otters and found that fecal swabbing consistently outperformed DETs buffer storage across both temperate and tropical environments. Swabbing yielded higher PCR and genotyping success rates while reducing genotyping errors, particularly when sampling anal jelly in tropical conditions ...

Fusión de suturas craneales en el delfín franciscana, Pontoporia blainvillei (Gervais and D'Orbigny, 1844) [PDF]

open access: yes, 2015
Se estudió la fusión de suturas craneales y su asimetría bilateral en el delfín franciscana, Pontoporia blainvillei. Nuestros resultados mostraron que el cierre de suturas presenta baja variabilidad asociada a la longitud corporal total, exceptuando la ...

Novel hemotropic mycoplasmas are widespread and genetically diverse in vampire bats [PDF]

open access: yes, 2017
Bats (Order: Chiroptera) have been widely studied as reservoir hosts for viruses of concern for human and animal health. However, whether bats are equally competent hosts of non-viral pathogens such as bacteria remains an important open question. Here,
