Ibis, EarlyView.Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina
Insect Conservation and Diversity, EarlyView.Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges
Insect Conservation and Diversity, EarlyView.Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Insect Conservation and Diversity, EarlyView.Ecological filters shape community assemblages. When filters lead to non‐Gaussian distributions—for example, asymmetric, uneven, multimodal—the community weighted mean is insufficient to characterise the community. Urban environments exert deterministic directional and stabilising assembly filters on functional communities in butterflies, with a higher

A Comparative Note on the Reliability of Inequality Indicator Estimates
International Statistical Review, EarlyView.Summary The importance of accurate measurement of economic or social inequality is generally accepted. Estimators of its most popular measure, the Gini coefficient, are commonly criticised for becoming increasingly imprecise for increasingly skewed distributions and small to moderate samples, i.e., two phenomena that we face more frequently today.
