BACKGROUND Comparing patterns of terrestrial and marine defaunation helps to place
human impacts on marine fauna in context and to navigate toward recovery. Defaunation …

Deserts and arid regions are generally perceived as bare and rather homogeneous areas of
low diversity. The S ahara is the largest warm desert in the world and together with the arid S …

Technological innovations have led to exciting fast-moving developments in science. Today,
we are living in a technology-driven era of biological discovery. Consequently, tracking …

Many populations of long‐distance migrants are declining and there is increasing evidence
that declines may be caused by factors operating outside the breeding season. Among the …

Electrocution on poorly designed power poles is increasingly shown to pose a threat for the
populations of many large raptors. Here we document that a power line in Sudan continues …

Understanding space use of free‐living endangered animals is key to informing
management decisions for conservation planning. Like most scavengers, vultures have …

Disentangling individual-and population-level variation in migratory movements is
necessary for understanding migration at the species level. However, very few studies have …

Satellite-tracking technology has allowed scientists to make a quantum leap in the field of
migration ecology. Nowadays, the basic description of migratory routes of many species of …

Supplementary feeding is one of the most common techniques used to alleviate threats to
scavengers species related to the quality and availability of food resources. Because …

Telemetry-based movement research has become central for learning about the behavior,
ecology and conservation of wide-ranging species. Particularly, early telemetry studies were …
