Abstract Background Despite decades of epidemiological theory making relatively simple assumptions about host movements, it is increasingly clear that non-random movements drastically affect disease transmission. To better predict transmission risk, needed quantifies the contributions both fine-scale space use and non-independent, correlated to dynamics. Methods We developed applied new relative non-independent spatio-temporal risk. Our decomposes pairwise risk into two components: (i)...
Abstract Despite decades of epidemiological theory making relatively simple assumptions about host movements, it is increasingly clear that non-random movements drastically affect disease transmission. To better predict transmission risk, needs to simultaneously account for how the environment affects space use and social dynamics correlation in use. We develop new decomposes relative contributions fine-scale correlated spatio-temporal risk. Using analytical results, simulations, empirical...
There has been a steady rise in the use of dormant propagules to study biotic responses environmental change over time. This is particularly important for organisms that strongly mediate ecosystem processes, as changes their traits time can provide unique snapshot into structure and function ecosystems from decades millennia past. Understanding sources bias variation challenge field resurrection ecology, including those arise because often-used measurements like seed germination success are...
Elk (Cervus canadensis) were reintroduced to Tennessee, USA in the early 2000s, with limited reproductive monitoring since initial release. We assessed efficacy of noninvasive sampling for determining pregnancy using invasive (capture) and (fecal collection field) techniques at North Cumberland Wildlife Management Area (NCWMA), Tennessee. captured 20 female elk 2019–2020, used pregnancy-specific protein B (PSPB) blood determine compared results fecal progesterone metabolite (FPM)...
North American elk Cervus canadensis inhabited portions of the eastern United States until extirpation in mid‐1800s. From 2000 to 2008, 201 were reintroduced Cumberland Wildlife Management Area (NCWMA), Tennessee. The stocking source was Elk Island National Park, Alberta Canada where there are two distinct genetic populations isolated from north and south. This structure has largely persisted population after translocation. Food habits evaluated early stages restoration, but had...
A female Odocoileus virginianus (White-tailed Deer) harvested in West Tennessee (29 January 2024) an area with high prevalence of chronic wasting disease (CWD), had 5 fetuses (3 males and 2 females). All similar development (58 days old) determined by crown–rump length. We estimated conception occurred ∼2 December 2023, typical for the area. This case suggests that reproductive output might be possible even face CWD. However, potentially output, altered maternal behavior due to CWD infection...
Comprehensive disease surveillance has not been conducted in elk (Cervus canadensis) Tennessee, US, since their reintroduction to the state 20 yr ago. We identified causes of death, estimated annual survival, and pathogens concern at North Cumberland Wildlife Management Area (NCWMA), US. In 2019 2020, we captured 29 (21 females, eight males) using chemical immobilization fitted individuals with GPS collars mortality sensors. Elk that died between February 2022 were necropsied identify death;...
