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 ...

Shepherds' perception of the effectiveness and feasibility of herd protection measures against wolf predation in Lower Saxony, Germany

open access: yesConservation Science and Practice, EarlyView.
We assessed shepherds' attitudes toward wolves and their perceptions of herd protection measures. Negative views were common among hobby shepherds and those affected by surplus killings, while professional and part‐time shepherds, especially those with minor attack experiences, held more neutral or positive attitudes.

open access: yesThe Economic History Review, EarlyView.
Abstract Between the seventeenth and twentieth centuries, billions of cowries arrived in West Africa, leaving one of the few quantitative traces available for historians to measure the Atlantic trade's impact on the precolonial market economy. Yet, current estimates substantially underestimate the volume of cowry imports.
