This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

Species richness declined along cave microclimatic gradient, while diversity increased with habitat heterogeneity, highlighting distinct roles of abiotic conditions and structural complexity in shaping arthropod communities. Functional traits shifted along the microclimatic gradient, with larger‐bodied and more eye‐regressed arthropods dominating under

Nest boxes as microhabitats supporting diverse arthropod communities
Diverse Micro‐Habitats: Nest boxes supported 3634 arthropods from 82 families, highlighting their significant conservation value as artificial micro‐habitats for diverse invertebrate communities beyond their primary use for birds. Occupancy Boosts Diversity: Occupied nests exhibited significantly higher arthropod richness, abundance and Shannon ...

We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

Counteracting selective pressures: Museum collections show declining Aglais io wing size
Using museum specimens, we found that forewing and hindwing length of Aglais io declined significantly between 1953 and 1984 across three north‐western German populations. The observed long‐term reduction in wing size in Aglais io is potentially linked to environmental change, with consistent patterns across all studied localities.

Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.
