Contrasting patterns of land use by resident and migratory bird assemblages in a tropical working landscape

Oikos, EarlyView.
The spatial configuration and management of agricultural and other land‐use practices can affect ecological assemblages. However, the differences in how resident and migratory birds respond to land‐use are remain unclear, hindering our understanding of bird biodiversity responses to land use.

Long‐term nutrient addition and grazing exclusion determine flower abundance, diversity and community composition in high‐latitude grasslands

Oikos, EarlyView.
The abundance and composition of flowers within plant communities shape the resources available to flower‐visiting insects. However, it remains unclear how nutrient enrichment and changes in grazing impact plant communities and their floral resources, and whether these effects contribute to ongoing pollinator decline. We investigated how the abundance,

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.
