Dawn of the dinosaurs demonstrates early diversification bursts and a potential role for neutral dynamics during major evolutionary radiations

Abstract Major radiations have given rise to huge swathes of life on Earth, and understanding their dynamics reveals the process of biodiversity generation itself. The rise of dinosaurs and other archosaurs during the Triassic was a spectacular example of such a radiation; it set...

Decrease in bird species richness and abundance after post-COVID-19 public reopening on paths of a high-attendance protected area

Context Protected areas (PAs) receive visitors pursuing environmental education and recreation objectives, but this can negatively affect the conservation of their biodiversity. Quantification of this impact is scarce, especially in developing countries. The Anthropause generated...

Environmental associations and spatial segregation among coexisting Pogonomyrmex harvester ant species in the central Monte desert (Argentina)

Abstract Background Ant communities are widely considered to be structured by interspecific competition. Seed-harvesting ants are dominant granivores in drylands, and their colony locations influence their spatio-temporal effect on plant communities. Three closely related species...

EFECT enables reliable and reproducible stochastic simulations across disciplines

Stochastic simulations underpin computational research in fields from systems biology and epidemiology to finance and physics-informed machine learning, yet their reproducibility is hard to quantify because each run yields different outcomes. Existing practices to improve computa...

eDNA Metabarcoding Reveals Spatial Patterns of Marine Communities Along the Beagle Channel (Tierra del Fuego, Argentina)

The Beagle Channel, located south of Tierra del Fuego (~54° S), is South America’s southernmost intracoastal ecosystem. Here, we applied environmental DNA metabarcoding using a partial sequence of the 12sRNA mitochondrial gene to evaluate the seasonal and spatial dynamics of mari...
