Forest type modulates mammalian responses to megafires

open access: yesScientific Reports
Although considered an evolutionary force responsible for shaping ecosystems and biodiversity, fires’ natural cycle is being altered by human activities, increasing the odds of destructive megafire events.

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

open access: yesConservation Biology, EarlyView.
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.

Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Monitoring small‐scale fisheries through participatory, app‐based surveys in the tropical archipelago of São Tomé and Príncipe

open access: yesConservation Science and Practice, EarlyView.
Small Island Developing States have limited capacity to monitor Small Scale Fisheries, despite their high dependence on marine resources. Participatory monitoring of Small Scale Fisheries can fill data gaps while integrating resource users into fisheries management.

What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...

Seasonality as a structuring factor of the dung beetle community in burned neotropical savannas

open access: yesEcological Entomology, EarlyView.
We tested the effects of fire, vegetation cover and seasonality on dung beetle communities, focusing on species richness, composition and co‐occurrence patterns in savannas. Fire did not affect species richness. However, seasonality was the dominant factor influencing species composition, followed by fire and vegetation cover.

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

open access: yesEcological Entomology, EarlyView.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.
