The State Of Animal- Assisted Interventions In France: Is The Iahaio Model Relevant?, Alice Mignot, Gérard Leboucher, Véronique Servais, Karelle De Luca
People and Animals: The International Journal of Research and Practice
Animal- assisted interventions (AAI) became more generalized in health care settings and their development in Europe is increasing. In France, the practice has grown in the absence of official recognition and regulation. In this context, we aim to identify the main characteristics of the French practice of AAI that can influence the establishment of a local regulation. Second, we aim to question the relevance of the model proposed by the International Association of Human- Animal Interaction Organizations (IAHAIO) distinguishing animal- assisted therapies (AAT) and (AAA) animal- assisted activities from the French practice of AAI. We interviewed 111 French handlers in …

Kentucky Equestrians: Defining Socioeconomic Contexts For Extension Programming, Kimberly I. Tumlin, Karin Pekarchik, Steven Claas
The Journal of Extension
Understanding relationships between demographic and economic factors and equestrian participation could improve horse program design. We implemented an online survey that characterized associations of participation in equine activities, socioeconomic factors, and economic factors with age. Seventy-five percent of respondents ride, and 34% are recreational, non-competitive participants. Respondents were mostly female, and many participate in the sport throughout life. Many respondents indicated they overspent on equestrian activities. Horse programs should incorporate information and activities that address issues unique to females, should develop skills required by amateur or recreational riders, and should incorporate information on financial wellness.

Human–Wildlife Interactions
Wild boar (Sus scrofa) is now an important species of wild ungulates in Central Europe. Next to conflicts of wild boar with agriculture, the main threat of wild boar presence lies in the expansion of African swine fever across Europe. The regulation of the wild boar population is complicated by the high reproduction rate and intelligent behavior of the species, which limits hunting effectiveness. We analyzed the spatial behavior of wild boar in an environment with a lack of natural food resources. The study area consisted of a forest complex (1,283 ha) with 2 areas. In the “risk” …

Self-Injurious Behavior In A Captive, Malimprinted Coragyps Atratus, Brittany Swartout
The Pegasus Review: UCF Undergraduate Research Journal
Lurch is a Coragyps atratus who was raised in captivity and imprinted on humans. He was an education animal at the Silver Springs Zoo until its closure. Lurch was moved to the Central Florida Zoo and has been feather picking and self-mutilating since then. Self-injury is not well documented in raptors and few treatments have been explored. It is often caused by stress of some sort and is not seen in the wild. These observations were conducted in order to observe the environmental factors that influenced these behaviors in Lurch. In an attempt to curb his feather picking, Lurch was …

A Decision Tool To Identify Population Management Strategies For Common Ravens And Other Avian Predators, Andrea F. Currylow, Brenda J. Hanley, Kerry L. Holcomb, Timothy Shields, Stephen Boland, William I. Boarman, Mercy Vaughn
Human–Wildlife Interactions
Some avian species have developed the capacity to leverage resource subsidies associated with human manipulated landscapes to increase population densities in habitats with naturally low carrying capacities. Elevated corvid densities and new territory establishment have led to an unsustainable increase in depredation pressure on sympatric native wildlife prey populations as well as in crop damage. Yet, subsidized predator removal programs aimed at reducing densities are likely most effective longer-term when conducted in tandem with subsidy control, habitat management, and robust assessment monitoring programs. We developed decision support software that leverages stage structured Lefkovitch population matrices to compare and identify treatment …
