—Lampropeltis getula is a species of conservation concern in several parts of its wide geographic range. I describe habitat use and movement patterns of L. getula holbrooki in an agricultural landscape, a portion of which has been brought out of agriculture and reforested. Both sexes strongly preferred vegetated shrubby levee habitats, and avoided active agricultural fields. There was no eviden...

Dispersal is a key component of a species's ecology and will be under different selection pressures in different parts of the range. For example, a long-distance dispersal strategy suitable for continuous habitat at the range core might not be favoured at the margin, where the habitat is sparse. Using a spatially explicit, individual-based, evolutionary simulation model, the dispersal strategie...

Core-periphery models allow predictions of persistence to be made with relatively little data. The rationale is that populations in the core of their geographical or ecological ranges occupy suitable habitats and exhibit higher and less variable densities. Populations along the peripheries tend to be more fragmented and therefore less likely to receive immigrants from other populations. A popul...

Interactions between animal behaviour and the environment are both shaping observed habitat use. Despite the importance of inter-specific interactions on the habitat use performed by individuals, most previous analyses have focused on case studies of single species. By focusing on two sympatric populations of large herbivores with contrasting body size, we went one step beyond by studying varia...

Fire over the past decade has affected forests in the San Bernardino Mountains of southern California, providing an excellent opportunity to examine how this disturbance, and subsequent post-fire salvage logging, influenced California spotted owl (Strix occidentalis occidentalis) breeding-season site occupancy dynamics there and in the nearby San Jacinto Mountains. Using occupancy survey data f...
