Abstract Wildlife managers consider animal translocation a means of increasing the viability local population. However, augmentation may disrupt existing resident disease dynamics and initiate an outbreak that would effectively offset any advantages have achieved. This paper examines fundamental concepts ecology identifies conditions will increase likelihood following translocation. We highlight importance susceptibility to infection, population size connectivity – characteristic likely...
Most directly transmitted infections require some form of close contact between infectious and susceptible hosts to spread. Often disease models assume contacts are equal use mean field estimates transmission probability for all interactions with hosts. Such methods may inaccurately describe when differ substantially in their ability cause infection. Understanding this variation risk be critical properly model manage diseases. In study, we investigate how varying exposure key understanding...
Abstract Context When human-made barriers impact wildlife by limiting habitat connectivity, simulation can reveal movements lost to fragmentation, strategies restore corridor function, and potential benefits of restoration. Objectives Guided previous genetic research, we examined desert bighorn sheep movement near two highways that restrict gene flow modelled their selection behavior. The ultimate goal was simulate without highway as a means site crossing structures mitigate fragmentation...
Ecologists regularly use animal contact networks to describe interactions underlying pathogen transmission, gene flow, and information transfer. However, empirical descriptions of often overlook some features individual movement, decisions about what kind network in a particular setting are commonly ad hoc . Here, we relate movement trajectories through tripartite model individual, space, time nodes. Most used studies (e.g. association networks, home range overlap spatial networks)...
Abstract The epidemiology of infectious diseases depends on many characteristics disease progression, as well the consistency these processes across hosts. Longitudinal studies infection can thus inform monitoring and management, but be challenging in wildlife, particularly for long-lived hosts persistent infections. Numerous tortoise species conservation concern infected by pathogenic mycoplasmas that cause a chronic upper respiratory tract (URTD). Yet, lack detailed data describing...
Abstract Immune function plays an important role in animal's defense against infectious disease. In reptiles, immune responses may be complex and counterintuitive, diagnostic tools used to identify infection, such as induced antibody are limited. Recent studies using gene transcription profiling tortoises have proven useful identifying various intrinsic extrinsic stressors. As part of a larger experiment with Mojave desert ( Gopherus agassizii ), we facilitated the transmission pathogenic...

Abstract Interactions between wildlife hosts act as transmission routes for directly transmitted pathogens and vary in ways that affect efficiency. Identifying drivers of contact variation can allow both inference estimation dynamics despite limited data. In desert tortoises, mating strategy, burrow use seasonal change influence numerous behaviours likely shape patterns. this study, we ask to what extent tortoise behaviour varies sexes seasons, whether space or burrow-use data be used infer...
To improve wildlife connectivity across the U.S., managers need to identify and prioritize movement barriers in of mitigation. Roadway may be semi-permeable allow some either at-grade or via non-wildlife underpasses, but permeability can depend on species-specific behaviors underpass characteristics. We used a combination trail cameras GPS collars monitor desert bighorn (Ovis canadensis nelsoni) near highways use underpasses along I-15 I-40 Mojave National Preserve, CA. After year 1, we...
Abstract For several species, refuges (such as burrows, dens, roosts, nests) are an essential resource for protection from predators and extreme environmental conditions. Refuges also serve focal sites social interactions including mating, courtship aggression. Knowledge of refuge use patterns can therefore provide information about structure, mating foraging success, well the robustness health wildlife populations, especially species considered to be relatively solitary. In this study, we...
