Changes in seed dispersal processes and the potential for between-patch connectivity for an arid land daisy [PDF]
, 2012 Dispersal is a major and critical process in population biology that has been particularly challenging to study. Animals can have major roles in seed dispersal even in species that do not appear specifically adapted to animal-aided dispersal.

State-space models' dirty little secrets: even simple linear Gaussian models can have estimation problems [PDF]
, 2016 State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often structured to account for two levels of variability: biological stochasticity ...

Biology Open, 2016 In birds, fat accumulation before and during migration has been shown to be endogenously controlled and tuned by, among other factors, the Earth's magnetic field.

L\'evy flights and self-similar exploratory behaviour of termite workers: beyond model fitting [PDF]
, 2014 Animal movements have been related to optimal foraging strategies where self-similar trajectories are central. Most of the experimental studies done so far have focused mainly on fitting statistical models to data in order to test for movement patterns ...

Forecasting wildlife movement with spatial capture–recapture
Methods in Ecology and Evolution, 2023 Wildlife movement is an important process affecting species population biology and community interactions in myriad ways. Studies of wildlife movement have focused on retrospectively estimating movements of small numbers of individuals by outfitting them

, 2022 Movement is a fundamental process in the natural world, and active movement in response to environmental drivers is key to animal ecology. The animal tracking revolution has led to at least two distinct challenges in the field of movement ecology. The first is how to gain ecologically meaningful insights into the proximate, mechanistic drivers of ...

Generalizing the first-difference correlated random walk for marine animal movement data [PDF]
, 2018 Animal telemetry data are often analysed with discrete time movement models assuming rotation in the movement. These models are defined with equidistant distant time steps. However, telemetry data from marine animals are observed irregularly.

Daily Evolution of the Insect Biomass Spectrum in an Agricultural Landscape Accessed with Lidar
EPJ Web of Conferences, 2016 We present measurements of atmospheric insect fauna intercepted by a static lidar transect over arable and pastoral land over one day. We observe nearly a quarter million of events which are calibrated to optical cross section.

Movement Ecology, 2018 Background Long-distance migration has evolved multiple times in different animal taxa. For insect migrants, the complete annual migration cycle covering several thousand kilometres, may be performed by several generations, each migrating part of the ...

Dystonia and paroxysmal dyskinesias: under-recognized movement disorders in domestic animals? A comparison with human dystonia/paroxysmal dyskinesias. [PDF]
, 2015 Dystonia is defined as a neurological syndrome characterized by involuntary sustained or intermittent muscle contractions causing twisting, often repetitive movements, and postures.
