Logging, linear features, and human infrastructure shape the spatial dynamics of wolf predation on an ungulate neonate - Ecological Applications, 2023

... In contrast to the 'human shield hypothesis' that posits prey use human-modified areas as refuge, wolves killed fawns closer to residential buildings than expected based on spatial availability. Fawns were also killed within recently-logged areas more than expected. Concealment cover was higher at kill sites than random sites, suggesting wolves use senses other than vision, likely olfaction, to detect hidden fawns. Wolves showed strong selection for hunting along linear features, and kill sites were also closer to linear features than expected...

A Genetic Predisposition to Chronic Wasting Disease in the Reindeer Rangifer tarandus in the Northern European Part of Russia  MV Kholodova, AI Baranova, IA Mizin, DV Panchenko… - Biology Bulletin, 2019

... It has been noted that due to the predominance of PrP genotypes with serine in codon 138 (138SS), which are associated with increased susceptibility to CWD, and the detection of this disease in reindeer, moose, and red deer in Scandinavia, there exists a real danger that CWD will spread among the reindeer inhabiting the European part of Russia...

Can genetic assignment tests provide insight on the influence of captive egression on the epizootiology of chronic wasting disease WL Miller, WD Walter - Evolutionary Applications, November, 2019

 ...Ancestry and assignment scores for two free-ranging deer with chronic wasting disease sampled in an area where chronic wasting disease was previously unobserved in free-ranging herds indicated a higher likelihood of assignment and proportion of ancestry attributable to captive populations. While we cannot directly assign these individuals to infected facilities, these findings suggest that rare egression events may influence the epizootiology of chronic wasting disease in free-ranging populations...


The demographic pattern of infection with chronic wasting disease in reindeer at an early epidemic stage A Mysterud, K Madslien, H Viljugrein, T Vikøren… - Ecosphere, 2019 Norway

... We found a strong sex-biased infection pattern in reindeer (with infection 2.7 times more likely in adult males), which is similar to the results reported in mule deer and white-tailed

deer. The hazard of being detected as positive increased with age in males. There was no close genetic relatedness among positive animals. The results were consistent with the within-group contact of males being a possible major route of transmission...


Differential gene expression in chronic wasting disease‐positive white‐tailed deer (Odocoileus virginianus) EK Trone‐Launer, J Wang, G Lu, NE Mateus‐Pinilla… - Ecology and Evolution, 2019 [PDF]

... We identified several genes that suggest a link between CWD and retroviruses and identified the gene ADIPOQ that acts as a tumor necrosis factor (TNF) antagonist.  This gene may lead to reduced production of TNF and impact disease progression and

clinical symptoms associated with CWD (i.e., wasting syndrome). Use of candidate genes identified in this study suggests the activation of endogenous processes in CWD‐positive deer, which in turn may enable earlier detection of the disease...

Detection of CWD in cervids by RT-QuIC assay of third eyelids 2019 US National Library of Medicine National Institutes of Health

...  We compared CWD detection by RT-QuIC and IHC in third eyelid, retropharyngeal lymph node, and brain in 10 deer in early symptomatic stage of disease. IHC detected PrPCWD deposition in third eyelid lymphoid follicles in 5 of 10 deer (50%) whereas third eyelids of all 10 animals were positive by RT-QuIC. This difference reflected in part a lower requirement for lymphoid follicle presence for seeding activity detection by RT-QuIC. In conclusion, RT-QuIC analysis of the third eyelid, an easily accessed tissue, has potential to advance CWD detection and testing compliance...

Cellular distribution of the prion protein in palatine tonsils of mule deer (Odocoileus hemionus) and Rocky Mountain elk (Cervus elaphus nelsoni)

MM Hille, JE Jewell, EL Belden - Journal of Veterinary Medical Science, 2019

... While CWD [chronic wasting disease] is a neurodegenerative disease, lymphoid accumulation of the abnormal isoform of the prion protein (PrPSc) is detectable early in the course of infection. It has been shown that a large portion of the PrPSc lymphoid accumulation in infected mule deer takes place on the surface of follicular dendritic cells (FDCs). In mice, FDC expression of PrPC has been shown to be essential for PrPSc accumulation...

Impacts of chronic wasting disease on a low density mule deer (Odocoileus hemionus) population in the San Andres Mountains, Chihuahuan Desert, New Mexico LC Bender, CL Rodden, P Mathis, ME Weisenberger… - ACTA ZOOLÓGICA …, 2019

... . Distribution of infected deer was strongly related to presence of other infected deer. Annual survival rates of mule deer and population rate-of-increase suggested little effect of CWD on population-level mortality given observed prevalence. Transmission and reservoirs of CWD in the SAM were likely limited by low deer densities, patchy distribution, and environmental characteristics (i.e., low clay content of soils) unfavorable to prion persistence, characteristics that are typical of most mule deer populations in the Chihuahuan Desert ecoregion...

...  Immunohistochemistry revealed that the moose shared the same neuropathologic phenotype, characterized by mostly intraneuronal deposition of PrPSc.  This pattern differed from that observed in reindeer and has not  been previously reported in CWD-infected cervids.  Moreover, Western blot revealed a PrPSc type distinguishable from previous CWD cases and from known ruminant prion diseases in Europe, with the possible exception of sheep CH1641. These findings suggest that these cases in moose represent a novel type of CWD...


Chronic wasting disease detection and mortality sources in semi-protected deer population

KL Schuler, JA Jenks, RW Klaver, CS Jennelle… - Wildlife Biology, 2018

... data best supported a model with time-invariant encounter probability and an annual survival of 72.8%. Even without direct pressure from hunting within the park, average life expectancy in this population was 3.2 years. Only 68% of mortalities contained sufficient material for CWD sampling (because of predation and scavenger activity) and >42% of these were CWD-positive. These findings underscore the possible biases in postmortem  surveillance estimates of disease prevalence because of potential for subclinical infected animals to be removed by predators and not tested.
