16.10.2018 EUCAW Speakers Argos-4 coming soon: a new momentum for the Argos system

Argos is a collaborative, international satellite system dedicated to environmental monitoring that has been flying for 40 years. Today, thanks to 6 operational satellites, it provides global coverage via its polar orbits, a unique robustness thanks to a communication protocol fitted for harsh conditions, — one of its main advantages…

16.10.2018 EUCAW Speakers Hammerhead Shark research: Knowledge from the populations in the Canary Islands

HAMMERHEAD SHARK RESEARCH is a project that studies hammerhead sharks Sphyrna spp in the Canary Islands with the aim to contribute scientific base knowledge of these species in an understudied distribution. Information of hammerheads in this distribution is limited to the presence of two species (S. lewini and S. zygaena),…

15.10.2018 EUCAW Speakers The annual cycle of German adult Ospreys (Pandion haliaetus) – studies in the breeding and wintering areas as well as during migration since 1995 by means of satellite telemetry

During 1995 – 2011 we marked 28 adult Ospreys in NE-Germany with satellite tags working up to eight years. All except three males wintered in West Africa. The migratory paths followed while in Europe seemed much straighter and more directional compared to the migratory paths followed in Africa. This pattern was…

15.10.2018 EUCAW Speakers Year-round Satellite Tracking of Amur Falcon (Falco amurensis) reveals the longest migration of any raptor species across the open sea

The title for undertaking the most arduous of all raptor migrations, belongs certainly to the Amur Falcon, which is a complete transcontinental, transequatorial, long-distance flocking migrant. The principal breeding (mainly NE China) and wintering (mainly S. Africa) ranges are separated by both 70° of latitude and longitude. Details of the…

09.10.2018 EUCAW Speakers Combining Argos and genetics to reveal connecting paths between juvenile and adult habitats in the Atlantic green turtle

At the European User Conference on Argos Wildlife, Philippine Chambault of IFREMER presents this fascinating project of the French Research agency IPHC-CNRS. Although it is commonly assumed that female sea turtles always return to the beach they hatched, the pathways they use during the years preceding their first reproduction and…

04.10.2018 EUCAW Speakers Tracking turtles to inform conservation

Brendan Godley, of University of Exeter has been tracking turtles using the ARGOS system for 20 years and has been involved in collaborative projects that have tagged over 500 hundred animals across the world. This has led to fundamental and applied insights for the populations in question but also provided…

01.10.2018 EUCAW Speakers The missing link: pelagic prey field prediction for Southern Ocean marine predators

Southern Ocean predators tend to lead cryptic lives, which in many cases are spent mostly at sea. This makes their foraging behaviour inherently difficult to study. Furthermore, numerous species are threatened through direct human conflict (such as fisheries related mortality), climate driven change, or both. At the European User Conference…

27.09.2018 EUCAW Speakers Using Argos for turtle dove management

Hervé Lormée, of the French Office National de la Chasse et de la Faune Sauvage, will present his work Argos at the European User Conference on Argos Wildlife (EUCAW). The European Turtle Dove Streptopelia turtur shows one of the most dramatic population decline among all farmland…
