Exploring Costa Rica's fungal trends: Insights from digitized specimens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

open access: yesZoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.
