“…Finally, the GPS system provides accurate time stamping of a position. When GPS was coupled with data transmission technologies (Rempel et al 1995;Rodgers et al 1996;Schwartz & Arthur 1999), a new era of animal tracking began, and recent literature contains numerous examples of successful studies using GPS positioning (Godley et al 2008;Gremillet et al 2008;Laurian et al 2008;Trathan et al 2008;Van Beest et al 2010).…”

Biologists can equip animals with global positioning system (GPS) technology to obtain accurate (less than or equal to 30 m) locations that can be combined with sensor data to study animal behaviour and ecology. We provide the background of GPS techniques that have been used to gather data for wildlife studies. We review how GPS has been integrated into functional systems with data storage, data transfer, power supplies, packaging and sensor technologies to collect temperature, activity, proximity and mortality data from terrestrial species and birds. GPS 'rapid fixing' technologies combined with sensors provide location, dive frequency and duration profiles, and underwater acoustic information for the study of marine species. We examine how these rapid fixing technologies may be applied to terrestrial and avian applications. We discuss positional data quality and the capability for high-frequency sampling associated with GPS locations. We present alternatives for storing and retrieving data by using dataloggers (biologging), radio-frequency download systems (e.g. very high frequency, spread spectrum), integration of GPS with other satellite systems (e.g. Argos, Globalstar) and potential new data recovery technologies (e.g. network nodes). GPS is one component among many rapidly evolving technologies. Therefore, we recommend that users and suppliers interact to ensure the availability of appropriate equipment to meet animal research objectives.

“…Although variable in different turtle species, the juveniles' spatial behaviour often involves longrange movements, especially during the initial pelagic phase of development, that occur in the oceanic environment (Musick & Limpus 1997). As adults, female turtles perform cyclical shuttling migrations between individually specific foraging and breeding areas (Luschi et al 2003;Godley et al 2008), which are probably undertaken by males as well Casale et al 2013a).…”

“…For males, the main difficulty lies in approaching the animals to tag them and deploy the satellite transmitters, since they very rarely leave the aquatic environment (e.g. Godley et al 2008;Arendt et al 2012a;Casale et al 2013a;Schofield et al 2013 and references therein). For juvenile turtles, the best available evidence on their spatial distribution has been obtained from genetic studies that have allowed the estimation of the contribution of different rookeries to the aggregations of juveniles frequenting a certain foraging area (e.g.…”

Understanding the at-sea spatial behaviour of sea turtles is a priority for their conservation. In the present paper, the current information on the distribution and movement patterns of the two species breeding in the Mediterranean, the loggerhead and the green turtle, is reviewed, focusing mainly on the 195 published routes of satellite-tracked turtles. A satisfactory level of knowledge about adults' migrations and other movements is reached only for loggerheads breeding at Zakynthos Island, Greece, and for green and loggerhead females nesting in Cyprus, while studies at foraging grounds are limited to loggerheads in the western and central parts of the basin. Adult males and females mostly show quite uniform post-breeding migratory patterns, typically moving towards individually specific neritic foraging grounds. A much higher variability is shown by loggerhead juveniles, which is probably associated with differences in their spatial behaviour while in oceanic or neritic waters. Evidence of seasonal migrations driven by lower temperatures in winter is available only for adult and juvenile loggerheads frequenting the two northernmost parts of the basin, i.e. the Ligurian and the northern Adriatic Sea. Current knowledge gaps and priorities for further research in the Mediterranean are discussed.

“…While the horizontal and vertical movements of large marine vertebrates are being increasingly described (Priede 1984, Duron-Dufrenne 1987, Polovina et al 2000, Block et al 2005, Bonfil et al 2005, remote recording of accurate spatial movements made by smaller species or early life stages has been slower, due to the challenges of miniaturising power sources, development of attachment techniques and hydrodynamic packaging of equipment (Watson & Granger 1998, Wilson & McMahon 2006, Pavlov et al 2007, Godley et al 2008). …”
