Ecosphere, Volume 16, Issue 12, December 2025.Abstract Emerging infectious diseases can cause rapid, widespread host mortality, and the lack of demographic data before and after pathogen emergence complicates understanding mechanisms of host persistence. This challenge is further compounded by environmental conditions that influence host behavior, while driving pathogen growth and virulence. These

Comparing Methods for Interpolation to Improve Raster Digital Elevation Models [PDF]
, 2012 Digital elevation models (DEMs) are available as raster files at 100m, 30m, and 10m resolutions for the contiguous United States and are used in a variety of geographic analyses. Some projects may require a finer resolution.

Ecosphere, Volume 16, Issue 12, December 2025.Abstract Dynamics of infectious disease in natural populations result from processes across scales, from host characteristics shaping exposure risk and susceptibility, to local environmental conditions driving vector populations, to the structure of metapopulation networks shaping transmission of pathogens across the landscape.

The implications of selenium deficiency for wild herbivore conservation: a review [PDF]
, 2018 Selenium (Se) is required at a fundamental physiological level in all animals. Adequate levels of Se are necessary for proper bone metabolism, iodine metabolism, immune function, reproductive success, and recruitment.

Acta Crystallographica Section F, Volume 81, Issue 12, Page 487-494, December 2025.This article describes the structural characterization of a short‐chain dehydrogenase from the pathogenic bacterium Brucella ovis. In this manuscript, two structures are described: the structure of the apo protein and a structure containing the coenzyme NAD+.Short‐chain dehydrogenases (SDRs) are a family of NAD(P)‐dependent enzymes involved in redox ...

Male reproductive pattern in a polygynous ungulate with a slow life-history: the role of age, social status and alternative mating tactics [PDF]
, 2018 According to life-history theory age-dependent investments into reproduction are thought to co-vary with survival and growth of animals. In polygynous species, in which size is an important determinant of reproductive success, male reproduction via ...

Pathogen Prevalence in Domestic Sheep in Western Nebraska: Implications for Bighorn Sheep Conservation and Coexistence on a Multi-Use Landscape [PDF]
, 2022 Bighorn sheep (Ovis canadensis) and domestic sheep (Ovis aries) are members of the same genus and thus share multiple pathogens that can be spread between them. One specific respiratory pathogen of concern is Mycoplasma ovipneumoniae (M.

Risk of pathogen spillover to bighorn sheep from domestic sheep and goat flocks on private land
Wildlife Society Bulletin, 2016 Bighorn sheep (Ovis canadensis) across North America have suffered population losses due to polymicrobial pneumonia typically initiated by spillover events of bacteria from domestic sheep and goats.
