Natural history museum collections often contain rare or difficult to obtain samples that could be used as a resource [...]
Landscape anthropization drives composition and diversity of butterfly communities at a regional scale
Published: 2025-02-26
Subjects: Biodiversity, Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Aim While landscape anthropization is a key driver of biodiversity change, its effects on communities are underexplored, especially at regional scales. In the Anthropocene, climate and habitat diversity alone are insufficient to explain community structure. However, until recently, ecologists lacked accessible, synthesized data describing anthropization gradients, which limited studies to [...]

While genetic diversity was [...]
Climate change intensifies plant-pollinator mismatch and increases secondary extinction risk for plants in northern latitudes
Published: 2025-02-19
Subjects: Biodiversity, Ecology and Evolutionary Biology
Climate change is altering the timing of species’ life-cycle events (i.e., phenology), but the rates of phenological shifts vary across taxa. These mismatches in phenological response may disrupt interactions between interdependent species, such as plants and their pollinators, which may lead to reduced plant reproduction via pollen limitation and contribute to secondary extinction risks for [...]

An influential biodiversity market may not direct investment towards habitats of national importance
Published: 2025-02-14
Subjects: Biodiversity
Biodiversity markets are proliferating globally, aiming to increase private investment to address conservation financing gaps. Markets commodify biodiversity to facilitate trade of biodiversity ‘units’ even across heterogeneous ecologies. However, the metric used to commodify biodiversity can strongly influence which habitats become valuable in biodiversity markets, and there has been little [...]
