Biotelemetry and biologging in endangered species research and animal conservation: relevance to regional, national, and IUCN Red List threat assessments
Abstract
The current biodiversity crisis is characterized by the decline and extinction of numerous animal populations and species world-wide.To aid in understanding the threats and causes of population decline and the assessment of endangerment status of a species, conservation scientists and practitioners are increasingly relying on remote assessments using biotelemetry (radio telemetry, acoustic telemetry, satellite tracking) and biologging (archival loggers) or hybrid technologies (e.g.pop-up satellite tags).These tools offer increasingly sophisticated means (e.g.large-scale telemetry arrays, fine-scale positioning, and use of physiological and environmental sensors) of evaluating the behaviour, spatial ecology, energetics, and physiology of free-living animals in their natural environment.Regional, national, and international threat assessments (e.g. the International Union for the Conservation of Nature [IUCN] Red List) require basic knowledge of animal distribution, emigration, behaviour, reproductive potential, mortality rates, and habitat use, which in many cases can all be obtained through biotelemetry and biologging studies.Such studies are particularly useful for understanding the basic biology of animals living in harsh environments (e.g.polar regions, aquatic environments), for rapidly moving or cryptic animals, and for those that undertake large-scale movements/migrations (e.g.birds, insects, marine mammals and fish).The premise of this paper is that biotelemetry and…
