2021, Ecology (102)
First-order dynamic occupancy models (FODOMs) are a class of state-space model in which the true state (occurrence) is observed imperfectly. An important assumption of FODOMs is that site dynamics only depend on the current state and that variations in dynamic processes are adequately captured with covariates...
Elk migration influences the risk of disease spillover in the Greater Yellowstone Ecosystem
Nathaniel D. Rayl, Jerod Merkle, Kelly Proffitt, E. S. Almberg, Jennifer D. Jones, Justin Gude, Paul C. Cross
2021, Journal of Animal Ecology (90) 1264-1275
Wildlife migrations provide important ecosystem services, but they are declining. Within the Greater Yellowstone Ecosystem (GYE) some elk (Cervus canadensis) herds are losing migratory tendencies, which may increase spatiotemporal overlap between elk and livestock (domestic bison [Bison bison] and cattle [Bos taurus]), potentially exacerbating pathogen transmission risk.We combined disease,...
Risky movements? Natal dispersal does not decrease survival of a large herbivore
Eric S. Long, Duane R. Diefenbach, Clayton L. Lutz, Bret D. Wallingford, Christopher S. Rosenberry
2021, Ecology and Evolution (11) 2731-2740
Natal dispersal is assumed to be a particularly risky movement behavior as individuals transfer, often long distances, from birth site to site of potential first reproduction. Though, because this behavior persists in populations, it is assumed that dispersal increases the fitness of individuals despite the potential for increased risk of...

Dean E. Biggins, Jerry L. Godbey, David A. Eads
2021, Vector-Borne and Zoonotic Diseases (21) 172-178
The plague bacterium, Yersinia pestis, is a generalist pathogen of flea (Siphonaptera) vectors and mammalian hosts. In colonies of prairie dogs (PDs, Cynomys spp.), Y. pestis causes occasional epizootics, killing ≥90% of PDs within weeks to several months. We evaluated the effectiveness of deltamethrin, a pyrethroid insecticide, as a tool for preventing plague epizootics among...

Airborne dust plumes lofted by dislodged ice blocks at Russell Crater, Mars
Cynthia L. Dinwiddie, Timothy N. Titus
2021, Geophysical Research Letters (48)
Linear dune gullies on poleward-facing Martian slopes are enigmatic. Formation by CO2-ice block or snow cornice falls has been proposed based on optical imagery of bright, high-albedo features inside gully channels. Because these features often resemble patchy frost residue rather than three-dimensional blocks, more evidence is needed to support the...

Thermokarst lakes accelerate deep permafrost thaw and the mobilization of previously frozen soil organic carbon. This leads to microbial decomposition and large releases of carbon dioxide (CO2) and methane (CH4) that enhance climate warming. However, the time scale of permafrost-carbon emissions following thaw is not well known...
