Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Revealing novelty from the southwestern Atlantic, Yemanjia gen. nov. and Olokunococcus gen. nov. from the coral cyanobiome of the Abrolhos Bank

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 533-555, April 2026.
Abstract Cyanobacteria comprise over 6000 species and inhabit diverse environments, including marine invertebrates such as sponges and corals. High‐throughput sequencing has indicated an abundance of Cyanobacteria communities in these hosts, yet taxonomic resolution has remained low below the phylum level.

Regions of Climatic Stability for Neotropical Primates

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
Spatial distribution of climatic stability, endemism, and model uncertainty for Neotropical primates. The left panel depicts projected climatic stability (warm colours = higher proportion of species with persistent climatic suitability; cool colours = lower stability). The upper‐right panel shows endemism (warm colours = higher concentration of endemic

HOWLish: a CNN for automated wolf howl detection

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 1, Page 58-70, February 2026.
Automated detection of wolf howls presents a great opportunity for large‐scale passive acoustic monitoring of wolf populations. Here we present HOWLish, a CNN trained for automated wolf howl detection, based on thousands of hours of soundscapes recorded in the wild.

Flash-drying for embryos desiccation Desidratação ultra-rápida de embriões

open access: yesPesquisa Florestal Brasileira, 2010
Seeds of several tree species from Brazilian wet forest are in dangerous situation and show recalcitrant characteristics. Therefore, it is not possible to store them by traditional methods adopted with orthodox seeds and it limits their genetic resources

To be or Not to be Hybrids? A Case‐Study in an Allochthonous Population Involving Illegal Introductions of the Endangered Golden‐Headed and Golden Lion Tamarins

open access: yesAmerican Journal of Primatology, Volume 88, Issue 1, January 2026.
Genetic analyses of an allochthonous population of Leontopithecus, illegally introduced into an area of the Brazilian Atlantic Forest in Rio de Janeiro, did not detect signs of hybridization. This data provides crucial information to support conservation efforts and prevent new threats to the endangered lion tamarins. ABSTRACT Allochthonous species can
