Moving in the Anthropocene : global reductions in terrestrial mammalian movements

Marlee A. Tucker, +135 more
- 26 Jan 2018 - 
TL;DR: Using a unique GPS-tracking database of 803 individuals across 57 species, it is found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in area with a low human footprint.

Dolphin-watching tour boats change bottlenose dolphin (Tursiops truncatus) behaviour

TL;DR: In this paper, a boat-based focal follows of schools of bottlenose dolphins was conducted to determine the effect of boats on dolphin behaviour, and a CATMOD analysis showed that behaviour differed by boat number, in particular, resting behaviour decreased as boat number increased.
Journal ArticleDOI

The magnetic sense and its use in long-distance navigation by animals.

TL;DR: Current technological advances in animal tracking devices now make it possible to test predictions from models of navigation based on the use of variations in magnetic intensity, and this work highlights the need to understand more fully the role of magnetism in animal navigation.
Journal ArticleDOI

Movement beyond the snapshot – Dynamic analysis of geospatial lifelines

TL;DR: A dynamic perspective to analysis is proposed which, in contrast to summary trajectory statistics on speed, motion azimuth or sinuosity, that refers to the variability of motion properties throughout the developing lifeline.
Journal ArticleDOI

Evidence that pigeons orient to geomagnetic intensity during homing

TL;DR: This study describes a novel behaviour which provides strong evidence that pigeons when homing detect and respond to spatial variation in the Earth's magnetic field—information of potential use for navigation.
