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

The available information regarding the 2 sea turtle species breeding in the Mediterranean
(loggerhead turtle Caretta caretta and green turtle Chelonia mydas) is reviewed, including …

Patterns of animal movement associated with foraging lie at the heart of many ecological
studies and often animals face decisions of staying in an environment they know versus …

For organisms that fly or swim, movement results from the combined effects of the moving
medium—air or water—and the organism's own locomotion. For larger organisms …

Over recent years, a major breakthrough in marine animal tracking has occurred with the
advent of Fastloc‐GPS that provides highly accurate location data even for animals that only …

The field of marine tagging and tracking has grown rapidly in recent years as tag sizes have
decreased and the diversity of sensors has increased. Tag data provide a unique view on …

Offspring and breeding (operational) sex ratios (OSR) are a key component of demographic
studies. While offspring sex ratios are often relatively easy to measure, measuring OSR s is …

Marine litter is any persistent, manufactured or processed solid material discarded, disposed
of or abandoned in the marine and coastal environment. Ingestion of marine litter can have …

The implications of climate change for global biodiversity may be profound with those
species with little capacity for adaptation being thought to be particularly vulnerable to …

Long-distance movements of animals are an important driver of population spatial dynamics
and determine the extent of overlap with area-focused human activities, such as fishing …
