A wild moose (Alces alces) calf was presented for necropsy due to severe neurologic signs. Histopathologic examination revealed multisystemic inflammation with intralesional mature and immature schizonts. Schizonts in the brain reacted positively to Sarcocystis spp. polyclonal antibodies. Gene sequencing of PCR-amplified DNA identified the species as Sarcocystis alceslatrans.

Department of Ecosystem Science and Management, University of Northern British Columbia, 3333 University Way, Prince George, British Columbia V2N 4Z9 (McVea, Richter, Rea); Applied Technology Group, TRIUMF, 4004 Wesbrook Mall, Vancouver, British Columbia V6T 2A3 (McLatchy).
Objective: Neonatal skeletal articulations for research and display purposes are uncommon due to issues surrounding incomplete bone maturation and reduced structural integrity that affect the bone preparation and articulation procedures. The present project was designed to add to the veterinary literature on neonatal moose osteological specimens, document the procedures of preparing and articulating a delicate specimen, and construct a 3-dimensional (3D) scan of the articulated skeleton that could be used for scientific and veterinary research and study worldwide.
Animal: A neonatal moose that had succumbed to capture myopathy resulting from entanglement in a barbed wire fence was the sole subject of this project.

Non-indigenous dung beetle (Coleoptera: Scarabaeoidea) species in North America are important contributors to ecosystem functions, particularly in pasture-based livestock systems. Despite the significant body of research surrounding non-indigenous (and often invasive) dung beetles in agricultural contexts, there has been minimal study concerning the impact that these species may have on indigenous dung beetle populations in natural environments. Here we examine the possible impact of the introduced dung beetle on indigenous dung beetle populations via use of indigenous mammal dung.

For species whose developmental stages or states are identifiable in photographs, there are opportunities for tracking population changes and estimating demographic rates. Recent developments in hierarchical models allow for the estimation of ecological states and rates over time for unmarked animals whose states are known.

Effects on physiology were evaluated in 49 free-ranging moose (Alces alces), 11 adult males, 36 females, two of unknown sex) in Minnesota, USA, immobilized by helicopter darting with thiafentanil (10 mg) and xylazine (30 mg) in February 2020 and March 2021. Pursuit time (PT), induction time (IT), recumbency time (RT), recovery time (RC), temperature (T), and body position were recorded. For 14 females, respiratory rate (RR), pulse rate (PR), and pulse oximetry (SpO2) were obtained before and at 1, 5, and 10 min after 4 L/min nasal oxygen supplementation was started; pH, lactate (Lac), arterial oxygen (PaO2), and carbon dioxide (PaCO2) tensions were obtained pre-treatment and 5 min post-treatment.

Article Synopsis
- Wildlife hosts a variety of piroplasm species that can impact both domestic animals and public health, highlighting their ecological significance.
- A study in Nevada tested 447 ruminants, finding 115 positive for piroplasms, with the highest infection rates among mule deer, followed by bighorn sheep and elk.
- Four species of piroplasms were identified, with Babesia duncani being the most prevalent, indicating significant diversity and potential zoonotic risks among free-ranging ruminants in the area.
