Quantifying spatiotemporally explicit interactions within animal populations facilitates the understanding of social structure and its relationship with ecological processes. Data from animal tracking technologies (Global Positioning Systems [“GPS”]) can circumvent longstanding challenges in the estimation of spatiotemporally explicit interactions,...
Wild pigs (Sus scrofa) are one of the most successful invasive species globally and are often implicated in agricultural damage. This damage is expected to increase as ranges of wild pigs expand, impacting the human food supply and increasing costs of food production. Our objective was to evaluate movement behaviors of wild pigs relative to resourc...
A 190-day finishing experiment was conducted to evaluate effects of feeding biochar on methane and carbon dioxide production, animal performance and carcass traits in beef steers. A high concentrate feedlot diet was used, and two dietary treatments were compared, 0 or 1% biochar as % of diet dry matter. Cattle were monitored using a calorimetry emi...
A feelot study compared the effects of corn silage inclusion on steer performance and carcass characteristics withing dry-rolled corn diets and steam-flaked corn diets. Treatments included four corn silage inclusions as 0, 15, 30, 45% of dry matter in both steam-flaked corn and dry-rolled corn base diets. Feeding a steam-flaked based corn diet incr...
A three-year experiment evaluated the effects of two supplementation strategies on yearling cattle performance and producer returns to management. Yearling cattle grazed on crested wheatgrass pastures and were supplemented either throughout the entire grazing season, only during the latter part of the grazing season, or not supplemented at all. The...
A simulation study investigated and provided potential solutions to practical issues that could arise from including gene-edited sires in routine genetic evaluations. Gene-editing is a technique for adding, deleting, or replacing nucleotides in the genome. Editing nucleotides controlling important socioeconomic traits (e.g., growth, carcass, diseas...
African swine fever (ASF) is a devastating hemorrhagic disease marked by extensive morbidity and mortality in infected swine. The recent global movement of African swine fever virus (ASFV) in domestic and wild swine (Sus scrofa) populations has initiated preparedness and response planning activities within many ASF-free countries. Within the US, fe...
Owls are mysterious creatures, mainly because we humans hardly ever encounter them. They are mostly nocturnal, are silent in their flight, and tend to unnerve us with their ghostly and sometimes quavering vocalizations. There have been numerous books on the natural history of owls written for nonexperts, but Jennifer Ackerman’s What an Owl Knows ta...
Raccoons (Procyon lotor) are routinely translocated both legally and illegally to mitigate conflicts with humans, which has contributed to the spread of rabies virus across eastern North America. The movement behavior of translocated raccoons has important ramifications for disease transmission yet remains understudied and poorly quantified. To exa...
The northern spotted owl (Strix occidentalis caurina; hereinafter NSO) was listed as “threatened” under the Endangered Species Act in 1990 and population declines have continued since that listing. Given the species’ protected status, any proposed activities on Federal lands that might impact NSO require consultation with U.S. Fish and Wildlife Ser...
