Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

Predation on Northern Silky Anteater (Cyclopes dorsalis) by Tiger Rat Snake (Spilotes pullatus) in a Rainforest Fragment in Costa Rica

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We report the first predation event of a northern silky anteater by a tiger rat snake. This predation underscores how little is known about the nocturnal anteater and its predators. As the snake is commensal with humans, anthropogenic habitat alterations might have exposed the anteater to a novel predation pressure.

Unraveling the Phenology of the Liana Marcgravia longifolia: Temporal Patterns and Climatic Cues

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We monitored the reproductive phenology of the Amazonian liana Marcgravia longifolia J. F. Macbr (Marcgraviaceae) for 84 consecutive months in the Peruvian Amazon to quantify the timing, synchrony, and seasonality of flowering and ripe fruiting. Flower presence peaked in August with intermediate synchrony, while ripe fruit presence peaked in November ...
