Declining habitat directive butterflies within a major stronghold: Challenges for conservation Rückläufige Tagfalter der FFH‐Richtlinie in einer bedeutenden Hochburg: Herausforderungen für den Naturschutz

open access: yesInsect Conservation and Diversity, EarlyView.
Myrmecophilous Phengaris nausithous and P. teleius are highly specialized grassland butterflies and flagship species for European nature conservation, but they exhibit ongoing population declines. We show strong declines for both species in the Westerwald mountain range, western Germany, since 1994, driven by inappropriate timing of mowing, grassland ...

Roadside pollinator populations and the negative impact of intensive roadside vegetation maintenance

open access: yesInsect Conservation and Diversity, EarlyView.
Less intensively managed roadsides had higher numbers of flower flies and bees; bee diversity was also higher in those roadsides. Community composition was similar across both management types, indicating that roadsides support a fairly homogeneous pollinator community, regardless of management.

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

open access: yesInsect 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 ...

Woody vegetation can promote pollinator biodiversity in semi‐natural grasslands

open access: yesInsect Conservation and Diversity, EarlyView.
Up to 24% shrub cover in Swedish semi‐natural grasslands is positively related to butterfly diversity, while butterfly diversity increases up to 18% deciduous hardwood tree cover. Initially positive effects of tree and shrub cover on butterfly abundance were detected on those butterflies that use trees and shrubs as host plants.

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

open access: yesInsect 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 ...
