Respondents were well educated and were most motivated towards their career as an equine journalist because of their interest in horses. …
Extending The Null Hypothesis To Invertebrate Pain Sentience, Eva Kakrada, Michael Colombo
Extending The Null Hypothesis To Invertebrate Pain Sentience, Eva Kakrada, Michael Colombo
Animal Sentience
In 1985 Macphail proposed his Null Hypothesis that there were no qualitative differences in intelligence across vertebrate species. A recent review of the literature has found overwhelming support for his view. Studies also suggest that, with respect to cognition and the neural mechanisms that support it, the Null Hypothesis should be extended to invertebrates. We suggest, on the same premise, that the Null Hypothesis should be extended to pain sentience in invertebrates. Although few studies have been conducted, behavioural and neural evidence for pain sentience has been found in various representative invertebrate species.
Wyoming’S Wild Horse Ranch: History And Description Of A Socio-Ecological Experiment, Alex Sas-Jaworsky, John Derek Scasta
Wyoming’S Wild Horse Ranch: History And Description Of A Socio-Ecological Experiment, Alex Sas-Jaworsky, John Derek Scasta
Human–Wildlife Interactions
The growing population of free-roaming horses (Equus ferus caballus) on western public rangelands has necessitated that federal agencies, such as the Bureau of Land Management (BLM) and U.S. Forest Service, develop novel approaches to curb growth including reproduction management. However, bureaucracy has hindered effective research and application of horse management on public lands and examples on private lands may present new solutions. Here we present the history and current population management strategy for the Wild Horse Ranch (WHR) located in southeastern Wyoming, USA, as an example of an ongoing private entity managing horses. Prior to 1985, this ~6,000-ha …
Partnerships Create Success For The Devil’S Garden Wild Horses, Laura K. Snell
Partnerships Create Success For The Devil’S Garden Wild Horses, Laura K. Snell
Human–Wildlife Interactions
Many wild horse (Equus ferus caballus) populations that inhabit designated federal land in the United States currently exceed management objectives. Overabundant wild horse populations can adversely impact the ecosystem, native wildlife, and other land uses. Unfortunately, there is not a universal solution, as each impacted area may differ ecologically, economically, socially, and politically. Wild horse management is not just a 1-time project but a long-term program where buy-in is needed from the federal and state agencies, local governments, and private partners. Local county governments and private partners can have important insights and significant influence on the development and …

Human–Wildlife Interactions
Mitigation translocation remains a popular conservation tool despite ongoing debate regarding its utility for population conservation. To add to the understanding of the effectiveness of mitigation translocation, in 2017 and 2018 we monitored a population of protected common chuckwallas (Sauromalus ater) following translocation away from the area of construction of a new highway near the South Mountains, Phoenix, Arizona, USA. We removed chuckwallas from the construction right-of-way, paint-marked and pit-tagged them, and then released them in a nearby municipal preserve. We deployed very high frequency radio-telemetry transmitters on a sub-sample of 15 translocated adult chuckwallas. We monitored the …

Nonnative Ungulate Impacts On Greater Sage-Grouse Late Brood-Rearing Habitat In The Great Basin, Usa, Mikiah R. Mcginn, Steven L. Petersen, Melissa S. Chelak, Randy T. Larsen, Loreen Allphin, Brock R. Mcmillan, Dennis L. Eggett, Terry A. Messmer
Human–Wildlife Interactions
Domestic livestock grazing is the dominant land use on much of the current range inhabited by greater sage-grouse (Centrocercus urophasianus; sage-grouse) in the western United States. Nonnative feral horses (Equus ferus caballus) also inhabit important sage-grouse seasonal habitats. Overabundant feral horse populations and improper grazing by domestic cattle (Bos taurus) can impact the health of sagebrush (Artemisia spp.) and desert shrub rangeland communities and native wildlife. These impacts to sage-grouse can be exacerbated when they affect late brood-rearing habitat, which provide the forbs and arthropods required to fledge broods. Managers require better information …

The Impact Of Covid-19 On Wildlife Strike Rates In The United States, Dan Parsons, Michael Malouf, Wayne Martin
Human–Wildlife Interactions
Shortly after the COVID-19 pandemic impacted air traffic, industry bodies warned of the potential increase in wildlife strike risk. Prior to the pandemic, wildlife strikes were already a concern to the industry. We sought to evaluate industry warnings using interrupted time series analysis of wildlife strike trends in the United States. Using pre-pandemic wildlife strike trends, we compared a forecast of the expected monthly strike rates through the COVID-19 impact period (March 2020 to December 2020) to the actual wildlife strike rates for the same period. Our results showed an increase in wildlife strike rates in 5 out of the …

Factors Affecting The Sex Ratio Of White-Tailed Deer (Odocoileus Virginianus) Fetuses In Arkansas, Jorista Garrie, Ralph Meeker
Factors Affecting The Sex Ratio Of White-Tailed Deer (Odocoileus Virginianus) Fetuses In Arkansas, Jorista Garrie, Ralph Meeker
Journal of the Arkansas Academy of Science
Health of the mother is known to affect the sex-ratio of the offspring in sexually dimorphic mammals. Both density-dependent and environmental factors (conditions at present, or seasonal conditions the year before) could impact the health of the mother. There are however two opposing hypotheses for whether a mother in good health should invest more in a strong son (that can father many offspring) or in a daughter (that can stay in the same area and use good resources). Fetuses from 1,208 female white-tailed deer (Odocoileus virginianus) were collected over a 10-year period (2002-2012), across 75 counties in Arkansas. …

A total of 1,833 mixed-sex growing-finishing pigs (PIC, 337 × 1050; initially 58.5 ± 1.62 lb) were used in a 112-d growth trial to determine the effects of adding L-Carnitine throughout the entire grow-finishing period or for just the last 28 d before marketing on growth performance and carcass characteristics. There were 26 replicate pens per treatment and 20 (group 1) or 27 (group 2) pigs per pen in a completely randomized design. There were three treatment diets: 1) control with no added L-Carnitine; 2) diets containing 50 ppm of L-Carnitine for the entire trial; and 3) control diet until …

Salmonella entericaserotype 4,[5],12:i:- (STM) has become an increasing problem for food safety and has been often detected in pork products. For this study, weanling pigs were exposed to STM-contaminated feed, water, or air to determine possible STM transmission routes. An uninoculated control group of pigs was included. The STM was monitored daily in feces and rectal and nasal swabs. The STM colonization was most prevalent in tissues from tonsil, lower intestine, and mesenteric lymph nodes. No differences in lesion severity were observed between inoculated and control pigs. Contaminated feed, water, and aerosolized particles caused infection in weaned pigs; however, …

A total of 3,451 mixed parity sows and their litters were used to evaluate the effects of essential fatty acid intake on sow reproductive performance, piglet growth and survivability, and colostrum and milk composition. At approximately d 112 of gestation, sows were blocked by parity within farrowing room and randomly assigned to 1 of 4 experimental treatments. Lactation diets were corn-soybean meal-wheat-based and included 0.5 (Control) or 3% choice white grease (CWG), 3% soybean oil (SO), or a combination of 3% soybean oil and 2% choice white grease (Combination). Thus, sows were provided diets with low essential fatty acid (EFA; …
