Environmental DNA succeeds in detecting a low‐density population of endangered harlequin frogs

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
This work evaluates the use of environmental DNA (eDNA) to detect the Critically Endangered Jambato Harlequin Frog (Atelopus ignescens)—an iconic species once thought extinct and now known only from a single locality in the Ecuadorian Andes. Our study demonstrates the effectiveness of eDNA in detecting the Jambato in a low‐density amphibian population,

Complementary Hotspots of Vegetation Diversity in Andean Patagonian Forests

Diversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim Examining spatial relationships among three vegetation diversity metrics—species richness (S), rarity‐weighted richness (RWR) and local contribution to beta diversity (LCBD) as a measure of compositional uniqueness and quantifying the spatial congruence of their hotspots to assess conservation value.

Impacts of Species Introductions on the Trait Diversity of Interacting Avian Frugivores and Fleshy‐Fruited Plants Depend on Native Trait Diversity

Global Ecology and Biogeography, Volume 35, Issue 10, October 2026.
ABSTRACT Aim The introduction of non‐native species to native ecological communities by humans is a major driver of global biodiversity change. Studying how species introductions influence interacting species is essential to understanding possible functional consequences of global change because biotic interactions are ecologically crucial.

A Time‐Calibrated Phylogeny and Historical Biogeography of Leptoceridae (Trichoptera): Diversification Shaped by Gondwanan Fragmentation and Conflicting Evidence for the Family's Origin

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Leptoceridae is the second most diverse caddisfly family, spreading across all biogeographical regions but with a higher species richness in the Oriental region; nevertheless, the Afrotropical, Austral and Neotropical regions have greater genera diversity and endemicity.

Fish Abundance and Functional Composition Are Associated With Water Type and Climate Across Amazonian Wetlands

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim We evaluate how Amazonian water types and broad‐scale climatic and productivity‐related proxies are associated with fish abundance and functional composition across wetlands. Location Amazon Basin, South America. Taxon Freshwater fishes. Methods We analysed fish assemblage data from 85 wetlands distributed across whitewater, blackwater and

Host and Environmental Factors Outweigh Pathogen in Shaping Skin Microbiome of a Threatened Andean Amphibian Community

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT The fungal pathogen Batrachochytrium dendrobatidis (Bd) has driven severe amphibian declines across the Neotropics, yet some species persist under enzootic pathogen conditions following epizootics. We investigated whether skin bacterial communities and host mucosome activity contributed to the persistence of seven amphibian species in a once ...
