Mechanisms of long-distance seed dispersal
TL;DR: To advance the understanding of LDD, this work advocates a vector-based research approach that identifies the significant LDD vectors and quantifies how environmental conditions modify their actions.

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.

Using tri-axial acceleration data to identify behavioral modes of free-ranging animals: general concepts and tools illustrated for griffon vultures
Ran Nathan,Orr Spiegel,Scott Fortmann-Roe,Roi Harel,Martin Wikelski,Wayne M. Getz,Wayne M. Getz +6 more
TL;DR: This work focuses on the use of tri-axial acceleration (ACC) data to identify behavioral modes of GPS-tracked free-ranging wild animals and illustrates how ACC-identified behavioral modes provide the means to examine how vulture flight is affected by environmental factors, hence facilitating the integration of behavioral, biomechanical and ecological data.
Journal ArticleDOI
Trends and missing parts in the study of movement ecology
TL;DR: In this article, the authors surveyed 1,000 randomly selected papers from 496 journals and compared the facets of movement studied with a suggested framework for movement ecology, consisting of internal state (motivation, physiology), motion and navigation capacities, and external factors (both the physical environment and living organisms), and links among these components.
Journal ArticleDOI
What's your move? Movement as a link between personality and spatial dynamics in animal populations.
TL;DR: A conceptual framework for personality-dependent spatial ecology is proposed that links expectations derived from the movement ecology paradigm with behavioural reaction-norms to offer specific predictions on the interactions between environmental factors, such as resource distribution or landscape structure, and intrinsic behavioural variation.
