Two scarlet macaws

28.07.2021 Animal tracking applications Argos Telemetry Collars Allow Scientists to Track Macaw Movement Patterns and Advocate for Expanded Protection

by Greta Hardy-Mittell Macaws are living in the wild – they are not “only” pets. Tracking Scarlet and Blue-and-Yellow Macaw with Argos enables to demonstrate that they move between protected and non-protected areas. Expanded Protection is thus needed to maintain their populations outside of protected areas. Photo: Two…

13.07.2021 Animal tracking applications Less oxygen in the ocean may mean more threats from fisheries for blue sharks

Blue sharks, as many pelagic species of sharks, are often found in the surface layers above the existing Oxygen Minimum Zones. Those layers might shrink due to climate change and the expansion of the oxygen-poor areas underneath, thus leading to a concentration of shark and their higher vulnerability…

21.12.2020 Animal tracking applications Sea turtles in tropical cyclones

Collecting sea turtle-borne temperature and depth sensor data with Argos satellite telemetry tags helps to sample the first 100 m layer of tropical oceans, where tropical storms and cyclones take their energy. It also enables to understand the behaviour of sea turtles trapped in extreme events such as tropical cyclones.

07.12.2020 Animal tracking applications Gull-billed terns keep their migration route and winter sites from year to year

Migratory birds may keep the same routes and the same nesting and wintering sites from year to year. Such species may be all the more fragile if environmental changes occur. Argos satellite telemetry enables researchers to be able to pinpoint those species, which may need more attention for conservation actions.
