Combining eDNA and Museomics to Enhance Biodiversity Monitoring
Published: 2025-02-26
Subjects: Biodiversity, Life Sciences, Other Ecology and Evolutionary Biology, Other Genetics and Genomics
Biodiversity changes due to human activities highlight the need for efficient biodiversity monitoring approaches. Environmental DNA (eDNA) metabarcoding offers a non-invasive method to assess species distributions, but its accuracy depends on comprehensive DNA reference databases. 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: 2025-02-25
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 [...]

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 [...]

Balancing data treatments with geographic and taxonomic representation in the Living Planet Index
Published: 2025-02-06
Subjects: Biodiversity
We set out the published, peer‑reviewed steps behind the Living Planet Index (LPI) and use these to frame why the patterns highlighted by Toszogyova et al occur. By explaining the reasoning behind our treatment of zeros and the inclusion of shorter or sparser time‑series, we show how different choices shape representation, highlighting the problem of addressing uneven data representation in the [...]
The collector practices that shape spatial, temporal, and taxonomic bias in herbaria
Published: 2025-02-05
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology
Natural history collections (NHCs) are essential for studying biodiversity. Although spatial, temporal, and taxonomic biases in NHCs affect analyses, the influence of collector practices on biases remains largely unexplored. We utilized one million digitized specimens collected in the northeastern United States from 237 herbaria and analyzed contributions from ~10,000 collectors. We investigated [...]
