Journal ArticleDOI
Transmitting species-interaction data from animal-borne transceivers through Service Argos using Bluetooth communication
Damian C. Lidgard,W. D. Bowen,Ian D. Jonsen,Bernie J. McConnell,Phil Lovell,Dale M. Webber,Stone Timothy Bruce,Sara J. Iverson +7 more
TL;DR: In this article, a Bluetooth link was integrated into the VMT and GPS satellite-linked transmitter to collect data on species interactions in otherwise inaccessible environments and without the need to recover instruments.
Journal ArticleDOI
Abundance estimates and habitat preferences of bottlenose dolphins reveal the importance of two gulfs in South Australia
Kerstin Bilgmann,Guido J. Parra,Lauren Holmes,Katharina J. Peters,Katharina J. Peters,Ian D. Jonsen,Luciana M. Möller +6 more
TL;DR: The high densities of bottlenose dolphins in the two gulfs highlight the importance of these gulfs as a habitat for the species and should inform management strategies, marine park planning and environmental assessments of potential anthropogenic threats to this protected species.
Journal ArticleDOI
A Water Mass Classification Approach to Tracking Variability in the East Australian Current
Lachlan R. Phillips,Gemma Carroll,Gemma Carroll,Ian D. Jonsen,Robert Harcourt,Moninya Roughan +5 more
TL;DR: In this paper, a machine-learning classification approach was developed to quantify variability in coastal EAC dynamics along a latitudinal gradient within the EAC extension zone in southeastern Australia, showing significant decadal-scale changes to EAC's dynamics in the region.
Journal ArticleDOI
Inter- and intrasex habitat partitioning in the highly dimorphic southern elephant seal
Mark A. Hindell,Clive R. McMahon,Clive R. McMahon,Ian D. Jonsen,Robert Harcourt,Fernando Arce,Christophe Guinet +6 more
TL;DR: In the case of the southern elephant seal, the authors of as mentioned in this paper found that the intersexual differences in habitat use existed before the divergence in body size and that the amount of energy gained was the same in all of the major habitats.
Journal ArticleDOI
Putting the behavior into animal movement modeling: Improved activity budgets from use of ancillary tag information
Sophie Bestley,Sophie Bestley,Sophie Bestley,Ian D. Jonsen,Robert Harcourt,Mark A. Hindell,Mark A. Hindell,Nick Gales +7 more
TL;DR: Two state‐space models adapted to incorporate ancillary data to inform three discrete movement states: directed, resident, and an activity state are presented, reinforcing previously raised contentions about the drawbacks of behavioral states inferred solely from horizontal movements.
