A global assessment of animal community responses to agricultural management

open access: yesConservation Biology, EarlyView.
Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

Coinvasional disruptions to island pollinator networks

open access: yesConservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Effects of restoration practices on biodiversity in temperate and boreal forests

open access: yesConservation Biology, EarlyView.
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.
