Migratory soaring birds exhibit spatiotemporal variation in their circannual movements. Nevertheless, it remains uncertain how different winter environments affect the circannual movement patterns of migratory soaring birds. Here, we investigated annual movement strategies of American white pelicans Pelecanus erythrorhynchos (hereafter, pelican) fr...

Background: Migratory soaring birds exhibit spatiotemporal variation in their circannual movements. We hypothesized that the circadian and seasonal movements of soaring migrants may depend primarily on exogenous factors such as thermals and wind conditions. Nevertheless, it remains uncertain how different winter environments affect the circannual m...

Spatial distribution and habitat selection are integral to the study of animal ecology. Habitat selection may optimize the fitness of individuals. Hutchinsonian niche theory posits the fundamental niche of species would support the persistence or growth of populations. Although niche‐based species distribution models (SDMs) and habitat suitability...

Spatiotemporal variation in space use is critical to understanding how individual animals respond to changes in resource heterogeneity across space and time. In particular, variation in space use across landscapes is of interest to wildlife ecologists and managers to determine mechanistic understanding of resource use under varying resource availab...

The abundance of tree seeds is a key parameter affecting the abundance and fluctuations of rodent populations. Nevertheless, despite extensive research on the relationships between seeds and rodent populations, we have an inadequate understanding of the demographic mechanisms by which seed abundance influences population density and population grow...
