Complex landscapes, complex diets: DNA metabarcoding reveals lady beetle prey richness increases with landcover diversity

open access: yesEcological Applications, Volume 36, Issue 3, April 2026.
Abstract Understanding the capacity of mobile organisms such as insects to utilize resources across different patches in a landscape can reveal strategies for their conservation. Past research suggests that higher levels of non‐crop habitat or landcover diversity in agricultural regions typically benefit generalist predators who can fortify their diets

Phylogenetic Analyses of True Ladybirds (Coleoptera: Coccinellidae: Coccinellini) Reveal Directionality in Diet Evolution and Support a Boreotropical Origin of the Tribe

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
A newly generated large‐scale molecular phylogeny of true ladybirds (Coccinellini) clarifies their evolutionary relationships and supports a boreotropical origin in the Paleocene, with multiple independent southward dispersals. Ancestral diet reconstructions suggest an initial specialization on aphids, followed by expansions in host range and ...

Spatial ecology and habitat selection of translocated European bison in the Romanian Carpathians

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Large herbivores play a critical role in maintaining ecosystem structure and function, yet their decline has disrupted ecological processes across much of the world. Species reintroductions aim to restore these dynamics, but how animals adapt to novel environments remains a key knowledge gap. European bison (Bison bonasus) are keystone species

Evaluating the potential of RNA interference for control of striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae)

open access: yesPest Management Science, Volume 82, Issue 4, Page 3591-3602, April 2026.
SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...
