TLDR
Recently developed, low-powered, TrackTag™ GPS loggers were used to track the movements of female loggerhead sea turtles at the largest breeding population in the Mediterranean (Zakynthos, Greece).About:

State-space models of individual animal movement.
Toby A. Patterson,Toby A. Patterson,Len Thomas,Chris Wilcox,Otso Ovaskainen,Jason Matthiopoulos +5 more
TL;DR: The statistical robustness and predictive ability of state-space models make them the most promising avenue towards a new type of movement ecology that fuses insights from the study of animal behaviour, biogeography and spatial population dynamics.
Journal ArticleDOI
Animal ecology meets GPS-based radiotelemetry: a perfect storm of opportunities and challenges
TL;DR: It is discussed how knowing where animals go can help scientists in their search for a mechanistic understanding of key concepts of animal ecology, including resource use, home range and dispersal, and population dynamics.

Satellite tracking of sea turtles: Where have we been and where do we go next?
Brendan J. Godley,J. M. Blumenthal,Annette C. Broderick,Michael S. Coyne,Matthew H. Godfrey,Lucy A. Hawkes,Matthew J. Witt +6 more
TL;DR: A comprehensive review of over 130 scientific papers on the use of satellite tracking for the fundamental and applied study of marine turtles shows how satellite tracking has changed over time as well as outlining biases in spatial, species and life- stage coverage.

State‐dependent risk‐taking by green sea turtles mediates top‐down effects of tiger shark intimidation in a marine ecosystem
Michael R. Heithaus,Alejandro Frid,Aaron J. Wirsing,Lawrence M. Dill,James W. Fourqurean,Derek A. Burkholder,Jordan A. Thomson,Lars Bejder +7 more
TL;DR: This study suggests that declines in large-bodied sharks may affect ecosystems more substantially than assumed when non-lethal effects of these top predators on mesoconsumers are not considered explicitly.
Journal ArticleDOI
Classifying movement behaviour in relation to environmental conditions using hidden Markov models.
TL;DR: The hidden Markov model (HMM) is examined for behavioural analysis of tracking data to allow for prediction of latent behavioural states while directly accounting for the serial dependence prevalent in ETT data.

Advances in marine conservation: the role of marine protected areas
TL;DR: The world's oceans are now attracting the serious attention of conservationists as discussed by the authors. But as the value of marine biological diversity is recognized, the ecosystems that harbor this diversity are fast becoming degraded.

Removing GPS collar bias in habitat selection studies
Jacqueline L. Frair,Scott E. Nielsen,Evelyn H. Merrill,Subhash R. Lele,Mark S. Boyce,Robin Munro,Gordon B. Stenhouse,Hawthorne L. Beyer +7 more
TL;DR: In this article, the effects of bias in resource selection functions (RSF) and compared the effectiveness of two bias-correction techniques (sample weighting and iterative simulation) were investigated.
Journal ArticleDOI
Habitat use and foraging behavior of tiger sharks (Galeocerdo cuvier) in a seagrass ecosystem
TL;DR: This study shows that using appropriate analysis techniques and a variety of field methods it is possible to elucidate the factors influencing habitat use and gain insights into the foraging behavior of elusive top predators.
Journal ArticleDOI
The implications of location accuracy for the interpretation of satellite-tracking data
TL;DR: Once more detailed aspects of Argos tracking data are considered, such as the speed of travel or small-scale movements, then location accuracy is likely to become a much more important issue.

A review of long-distance movements by marine turtles, and the possible role of ocean currents
TL;DR: Major oceanographic processes (such as main currents and eddies) have been recently shown to have a remarkable influence on leatherback movements, making it questionable whether these journeys are to be considered migrations or, rather, prolonged stays in vast feeding areas.
