Context Niche theory is frequently used as a framework to integrate environmental variables and species interactions to describe species geographic distribution. Yet, the scale at which species respond to the environment and other species is rarely considered in species distribution modeling. Here we examined the effect of spatial scale on species...

Camera traps are an increasingly popular means to monitor wildlife populations. However, like other techniques for measuring populations, camera traps are subject to sources of error that may bias population estimates. Past studies accounting for detection error have failed to account for a simple but potentially widely pervasive source of environm...
Article
Home range estimation is an important analytical method in applied spatial ecology, yet best practices for addressing the effects of spatial variation in detection probability on home range estimates remain elusive. We introduce the R package “DiagnoseHR,” simulation tools for assessing how variation in detection probability arising from landscape,...

Understanding patterns of space-use by individuals, their distribution, and how they coexist with ecologically similar species is crucial to address various issues in ecology, evolution, conservation biology, and wildlife management. However, the study of such patterns challenging because the relationship among species and their environment is shap...

We present a hands-on outdoor activity coupled with classroom discussion to teach students about wildlife habitat selection, the process by which animals choose where to live. By selecting locations or habitats with many benefits (e.g., food, shelter, mates) and few costs (e.g., predators), animals improve their ability to survive and reproduce. Bi...

The utilization of species distribution model(s) (SDM) for approximating, explaining, and predicting changes in species’ geographic locations is increasingly promoted for proactive ecological management. Although frameworks for modeling non-invasive species distributions are relatively well developed, their counterparts for invasive species—which m...

Understanding patterns of space-use by individuals, their distribution, and how they coexist with ecologically similar species is crucial to address various issues in ecology, evolution, conservation biology, and wildlife management. However, the study of such patterns challenging because the relationship among species and their environment is shaped by multiple ecological processes, many of which are acting at different scales, often in a hierarchical manner. In the Canidae family, for instance, where interference competition appears critical, larger species such as coyotes (Canis latrans), can often affect smaller species, such as red fox (Vulpes vulpes) and swift fox (Vulpes velox), by killing or displacing foxes. As such, increases in the abundance and distribution of coyote following the development of the western Nebraska may have inadvertently restricted the range of swift fox (state endangered species) despite the availability of suitable habitat. In this study we aimed (1) to understand how land cover variables were associated with species occurrence and test the effect that presence of intraguild competitors have on the predictive distribution of the focal species (swift fox); (2) to investigate if temporal segregation among species may be the mechanism allowing their coexistence; and (3) to assess the genetic structure and diversity of swift fox population in Nebraska and explored whether or not genetic structure could be influenced by landscape feature and habitat constraints. Overall, our results reiterated the importance of native shortgrass prairies, at small scale, for the occurrence and distribution of swift fox, and showed that increases of tree, row-crops, and developed areas, at larger scales, would have negative effects on the species’ occupancy. Intraguild interactions do not seemed to be a significant force affecting swift fox occupancy. We found seasonal differences in activity patterns overlap among species and that differences in canid body size can predict the degree of their temporal separation. Our result suggest that swift fox population in Nebraska is restricted to two subpopulations within its available habitat, but without clear genetic structure and geographic isolation; gene flow among populations is occurring within Nebraska and across the larger region. However, our findings draw attention to the potential for future reduction of genetic diversity due to swift fox small population size in light of increasingly diminished and fragmented suitable habitat.
