ABSTRACT Infectious disease contributed to historical declines and extirpations of bighorn sheep ( Ovis canadensis ) in North America continues impede population restoration management. Reports pneumonia outbreaks free‐ranging following contact with domestic have been validated by the results 13 captive commingling experiments. However, ecological etiological complexities still hinder our understanding control respiratory wild sheep. In this paper, we review literature summarize recent data...
Context Timing (mean birthdate) and synchrony (variance around that date) of births can influence survival young growth in ungulate populations. Some restored populations ungulates may not adjust these life-history characteristics to environments release sites until several years after release, which success reintroductions. Aims We quantified timing from 2005 2007 four reintroduced bighorn sheep (Ovis canadensis) occupying two ecoregions (Central Basin Range Wasatch Uinta Mountains) Utah,...
Abstract The influence of human harvest on evolution secondary sexual characteristics has implications for sustainable management wildlife populations. phenotypic consequences selectively removing males with large horns or antlers from ungulate populations have been a topic heightened concern in recent years. Harvest can affect size horn‐like structures two ways: (a) shifting age structure toward younger classes, which reduce the mean structures, (b) selecting against genes that produce...
Timing of births in ungulates is influenced by ecological factors, and differences seasonality have evolutionary implications for these mammals. Birthing habitat one the most important home-range attributes ungulates, disturbances during this time can decrease survival young population growth. We calculated timing quantified selected nursery groups desert bighorn sheep (Ovis canadensis nelsoni) to produce project a GIS model habitat. then applied that identify suitable an adjacent area Rocky...
Monitoring dispersal, habitat use, and social mixing of released ungulates is crucial for successful translocation species conservation. We monitored 127 female bighorn sheep (Ovis canadensis) in three populations from 2000 to 2009 investigate if augmented bighorns expanded shifted seasonal ranges, used different compared with resident females, animals mixed socially. Augmented all range use residents by shifting utilization distributions. Size distributions, however, were smaller females...
Abstract Secondary sexual traits (e.g., horns and antlers) have ecological evolutionary importance are of management interest for game species. Yet, how these respond to emerging threats like infectious disease remains underexplored. Infectious pneumonia threatens bighorn sheep ( Ovis canadensis ) populations across North America we hypothesized it may also reduce horn growth in male sheep. We assess the effect on size using 12 herd datasets from western United States that had data. Disease...
We investigated causes of antler deformities in mule deer (Odocoileus hemionus) bucks from the Paunsaugunt Plateau southern Utah, US. A total 10 hunter-harvested and nine live-captured with six 43 normal antlers were included study. All screened by serology for exposure to epizootic hemorrhagic disease virus (EHDV) types 1, 2, 6, bluetongue virus, Brucella abortus, ovis, caprine arthritis, encephalitis bovine viral diarrhea (BVDV) 1 2. Serum testosterone trace minerals concentrations...
Abstract Long-term datasets are becoming increasingly important for assessing population- and species-level responses to a changing environment. Programs that record morphological measurements of horns, antlers, pronghorns were established in the early- mid-20th century collect biological information about animals possess large or pronghorns, which could be used assess effectiveness conservation efforts mammals North America. The general relevance books has been questioned because minimum...
Translocation of large mammals has become common practice for wildlife managers charged with conservation animals and their genetic integrity on increasingly modified landscapes. Translocations ungulates have occurred around the world varying outcomes. Although translocations been used to manage mule deer ( Odocoileus hemionus ) in western North America, only recently outcomes associated this management documented. Our objective was evaluate survival translocated comparison resident over...
