Weekend Overload: Day‐to‐Day Fluctuations of Outdoor Recreation Affect Wild Mammals' Space‐Use in a Popular Forest Reserve Near Florence, Italy

Animal Conservation, EarlyView.
In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

From glacial echoes to timber pathways: Climatic–historical drivers and timber‐trade influence on the phylogeography of Ips sexdentatus in the Basque Country

Agricultural and Forest Entomology, EarlyView.
Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers
