Movements of a Juvenile Crowned Eagle (<em>Harpyhaliaetus Coronatus</em>) Tracked by Satellite Telemetry in Central Argentina
Background: A juvenile Crowned Eagle was tagged at its nest with a satellite transmitter. The Crowned Eagle (Harpyhaliaetus coronatus) is one of the most unknown raptor species from the American continent. Their current distribution ranges from central Brazil to central Argentina, with a total population of 350–1500 individuals across this large area, being thus largely fragmented. Results: Dur...
متن کاملThe role of individual variation in marine larval dispersal

Nanninga, Red Sea Research Center, King Abdullah University of Science and Technology, 4700 KAUST, Thuwal 23955-6900, Saudi Arabia e-mail: gerrit.nanninga@ kaust.edu.sa The exchange of individuals among patchy habitats plays a central role in spatial ecology and metapopulation dynamics. Dispersal is frequently observed to vary non-randomly within populations (e.g., sh...
متن کاملInferring Foraging Areas of Nesting Loggerhead Turtles Using Satellite Telemetry and Stable Isotopes
In recent years, the use of intrinsic markers such as stable isotopes to link breeding and foraging grounds of migratory species has increased. Nevertheless, several assumptions still must be tested to interpret isotopic patterns found in the marine realm. We used a combination of satellite telemetry and stable isotope analysis to (i) identify key foraging grounds used by female loggerheads nes...
متن کاملSatellite Telemetry and Long-Range Bat Movements
BACKGROUND Understanding the long-distance movement of bats has direct relevance to studies of population dynamics, ecology, disease emergence, and conservation. METHODOLOGY/PRINCIPAL FINDINGS We developed and trialed several collar and platform terminal transmitter (PTT) combinations on both free-living and captive fruit bats (Family Pteropodidae: Genus Pteropus). We examined transmitter wei...
