Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and
