Cytogenetics of two hylid frogs from Brazilian Cerrado

open access: yesGenetics and Molecular Biology, 2018
Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans.

Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.

Hide and Seek: Species Detectability in a Biodiversity Hotspot Increased by Environmental DNA

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
We demonstrated through Bayesian modeling that eDNA metabarcoding offers equivalent or higher detectability than traditional field inventory techniques for anuran species in a biodiversity hotspot. The number of recorded species was also higher in seven out of ten sampled streams.

Scinax acuminatus

open access: yes, 2011
Scinax acuminatus (fig. 1 A). In Aquidauana (MS), one male of Scinax acuminatus (38.1 mm SVL; one male) was recorded while calling hidden on grass vegetation about the soil level at the margins of a small dammed stream and another one while calling ...

Investigating the behavioral responses of nektonic and benthic tadpoles elicited by the presence of a predatory nektonic fish

open access: yesJournal of Zoology, Volume 326, Issue 3, Page 268-276, July 2025.
Different defensive strategies are used by tadpoles to avoid or escape from predators, and it is possible that differences in the microhabitat of prey and predators influence the defensive strategies used by tadpoles. Therefore, we experimentally tested whether the presence of a nektonic fish predator (Oreochromis niloticus) reduces the time of ...

Collared Peccary Wallows are Hubs of Animal Activity and Diversity in a Central American Wet Forest

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
Collared peccary wallows are used by a diverse assemblage of vertebrates in a Central American tropical wet forest. Wallows had significantly higher vertebrate activity and diversity compared to surrounding forest. Wallow visitors included 13 amphibian, 2 reptile, 11 bird, and 16 mammal species, engaged in behaviors including reproduction, drinking ...
