Density and Biomass Estimates by Removal for an Amazonian Crocodilian, Paleosuchus palpebrosus. [PDF]
PLoS ONE, 2016 Direct counts of crocodilians are rarely feasible and it is difficult to meet the assumptions of mark-recapture methods for most species in most habitats.

New Mitogenomic Resources for the Caiman yacare (Daudin, 1802) From Bolivia
Ecology and Evolution, Volume 16, Issue 4, April 2026.New mitochondrial genomes were generated to enhance the mitochondrial genetic resources available for Caiman yacare. Mitochondrial genomes of approximately 16 kb were obtained through genome skimming using Illumina sequencing technology. The assemblies revealed a composition typical of vertebrate mitogenomes, including 13 protein‐coding genes, 2 rRNA ...

TAXON, Volume 75, Issue 2, April 2026.Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

PLoS ONE, 2016 Rising habitat loss is one of the main drivers of the global amphibian decline. Nevertheless, knowledge of amphibian diversity needed for effective habitat protection is still highly inadequate in remote tropical regions, the greater part of the Amazonia.

Characterization of the Shallow Oxygen Minimum Zone of the Eastern Tropical North Atlantic
Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.Abstract The Eastern Tropical North Atlantic (ETNA) hosts a shallow Oxygen Minimum Zone (sOMZ) extending roughly from 50 to 250 m depth, where oxygen concentrations typically fall to 40–60 μmol L−1. Despite its ecological and biogeochemical importance, the spatial and temporal characteristics of the hypoxic events that shape this sOMZ remain poorly ...
