Selective feeding and niche differentiation in adult boreal Odonata revealed by DNA metabarcoding

Ecological Entomology, EarlyView.
COI metabarcoding of faecal pellets from three sympatric Odonata species in boreal Swedish wetlands revealed Diptera‐dominated diets, with mosquitoes only a minor component despite high availability. The larger hawker Libellula quadrimaculata showed greater dietary variance than the smaller damselflies, indicating size‐ and foraging strategy‐dependent ...

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Regenerative wheat management: The relative effects of farm practices on the biodiversity of invertebrates

Insect Conservation and Diversity, EarlyView.
Wheat in North America harbours a diverse insect community (565 morphospecies were identified in this study), and pests represented <7% of specimens collected. Regenerative wheat management promoted insect diversity without increasing pest populations.

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Interactions of land use and climate change disproportionately impact Lepidoptera of the five major insect orders

Insect Conservation and Diversity, EarlyView.
Land use and climate change are two major environmental pressures that interact to impact insect biodiversity. We compared the impacts of land use alone and of the interaction between land use and climate change on the five major insect orders. Most impacted were the Lepidoptera, showing 91% lower total abundance in sites of high‐intensity agriculture ...

When troglobites set the rules: How cave‐restricted species shape community responses in the richest tropical subterranean hotspot

Insect Conservation and Diversity, EarlyView.
Troglobites strongly shape community responses to environmental gradients, weakening patterns when excluded from analysis. High beta diversity dominated by species replacement, driven by distance from entrance and microclimatic factors. Resource availability and microclimate stability are key to maintaining this subterranean biodiversity hotspot ...
