Toward a functional understanding of novel fire regimes in tropical forests

open access: yesAmerican Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Using Environmental DNA Sampling for Simultaneous Detection of Hosts and Their Pathogens: A Case Study With the Critically Endangered Frog Genus Atelopus

open access: yesAnimal Conservation, Volume 28, Issue 5, Page 663-674, October 2025.
Environmental DNA is a powerful tool for simultaneous detection of rare species and their pathogens. We confirmed the presence of Atelopus at multiple sampling locations and found that the concentration of the amphibian pathogen Bd in eDNA samples was correlated with stream characteristics and the pathogen load of the amphibian community.
