Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

Fisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

Restoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...
