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.

26.11.2020 Animal tracking applications Whale sharks in St. Helena

27.10.2020 Animal tracking applications Is tracking marine animals really useful to their protection?

One of the most frequent rationale to fit animals with tracking devices is to help in conservation actions and regulations. In the marine animal case, is this argument only (or mostly) a wish, or are there real consequences consecutive to tracking studies? A study shows that the earlier the stakeholders…

05.10.2020 Animal tracking applications Black-tailed godwits’ different migration behaviours

Migratory birds from a given species are frequently observed to follow the same routes, and do so every year. Tracking different populations with Argos satellite telemetry shows a very different picture for some populations of the black-tailed godwit. Understanding why will need even more tracking.

03.08.2020 Animal tracking applications Tracking bottlenose dolphins by night in narrow channels

Dolphins do have a nightlife, but visual observation techniques cannot fully capture this. Also, coastal populations of dolphins sometimes occupy complex, labyrinthine habitats. Here too line-of-sight techniques fall short. Satellite telemetry doesn’t distinguish between night and day, and, as we will see, can track animals through an aquatic maze. This…
