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.
Journal ArticleDOI

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.
Journal ArticleDOI

Using tri-axial acceleration data to identify behavioral modes of free-ranging animals: general concepts and tools illustrated for griffon vultures

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.
