Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
PLANTS, PEOPLE, PLANET, EarlyView.Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Long‐term warming drives mineral‐associated organic carbon accumulation on the Tibetan Plateau
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Global warming affects both plant growth and soil microbial decomposition, creating uncertainty for the storage and persistence of soil organic carbon (SOC) stock. Limited decomposition rates often characterise cold alpine ecosystems.

Journal of Animal Ecology, EarlyView.Partial seasonal migration is rarely considered in a metapopulation context. Here, Haaland et al. use an eco‐evolutionary model revealing how partially migratory metapopulations may arise and be maintained, and how seasonal migrants may cause effects of local extreme climatic events to percolate through metapopulations across diverging temporal and ...
