Hunting A Home: The Abandonment And Neglect Of Hunting Dogs, Jamie B. Walker 2018 Germanna Community College

Hunting A Home: The Abandonment And Neglect Of Hunting Dogs, Jamie B. Walker

Exigence

Each year, an immeasurable number of hunting dogs are found in emaciated, malnourished or even abusive conditions due to neglect and abandonment by their owners. These dogs, primarily hounds, have increasingly become a burden on animal shelters and have cast a negative light on hunting with dogs, particularly in Virginia. The difficulty in identifying the owners of these dogs has stymied law enforcement and animal welfare authorities for years. Mandatory microchipping, now compulsory in England, may be the key to protecting talented working dogs from neglect, cruelty and abandonment by uncaring owners. These microchips can allow abandoned animals to lead ...


Dog Behavior Co-Varies With Height, Bodyweight And Skull Shape, Paul D. McGreevy, Dana Georgevsky, Johanna Carrasco, Michael Valenzuela, Deborah L. Duffy, James A. Serpell 2018 University of Sydney

Dog Behavior Co-Varies With Height, Bodyweight And Skull Shape, Paul D. Mcgreevy, Dana Georgevsky, Johanna Carrasco, Michael Valenzuela, Deborah L. Duffy, James A. Serpell

Paul McGreevy, Ph.D.

Dogs offer unique opportunities to study correlations between morphology and behavior because skull shapes and body shape are so diverse among breeds. Several studies have shown relationships between canine cephalic index (CI: the ratio of skull width to skull length) and neural architecture. Data on the CI of adult, show-quality dogs (six males and six females) were sourced in Australia along with existing data on the breeds’ height, bodyweight and related to data on 36 behavioral traits of companion dogs (n = 8,301) of various common breeds (n = 49) collected internationally using the Canine Behavioral Assessment and Research Questionnaire (C-BARQ ...


Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. McElligott 2018 Queen Mary University of London

Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. Mcelligott

Christian Nawroth, Ph.D.

Variation in common personality traits, such as boldness or exploration, is often associated with risk–reward trade–offs and behavioural flexibility. To date, only a few studies have examined the effects of consistent behavioural traits on both learning and cognition. We investigated whether certain personality traits (‘exploration’ and ‘sociability’) of individuals were related to cognitive performance, learning flexibility and learning style in a social ungulate species, the goat (Capra hircus). We also investigated whether a preference for feature cues rather than impaired learning abilities can explain performance variation in a visual discrimination task. We found that personality scores were consistent ...


A Note On Pigs’ Knowledge Of Hidden Objects, Christian Nawroth, Mirjam Ebersbach, Eberhard von Borell 2018 Martin Luther University

A Note On Pigs’ Knowledge Of Hidden Objects, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell

Christian Nawroth, Ph.D.

Object permanence is the notion that objects continue to exist even when they are out of observer’s sight. This ability is adaptive for free ranging animals who have to cope with a dangerous and highly changeable environment and allows them to be aware of predators sneaking in their proximity or to keep track of conspecifics or food sources, even when out of sight. Farm animals might also benefit from object permanence because the ability to follow the trajectory of hidden food or objects may lead to a higher predictability of subjects’ environment, which in turn might affect the level ...

Muskrats, James E. Miller 2018 Mississippi State University

Muskrats, James E. Miller

Wildlife Damage Management Technical Series

The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States (Figure 1). It spends its life in aquatic habitats and is well adapted for swimming.

Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth.

Muskrats also cause damage by eating agricultural crops, other vegetation, and crayfish, mussels and other aquaculture products. Loss of vegetation from muskrat ...


Wild Turkeys, James E. Miller 2018 Mississippi State University

Wild Turkeys, James E. Miller

Wildlife Damage Management Technical Series

Like other bird and mammal species whose populations have been restored through conservation efforts, wild turkeys (Figure 1) are treasured by many recreationists and outdoor enthusiasts. Wild turkeys have responded positively to wildlife habitat and population management. In some areas, however, their increased populations have led to increased damage to property and agricultural crops, and threats to human health and safety. Turkeys frequent agricultural fields, pastures, vineyards and orchards, as well as some urban and suburban neighborhoods. Because of this, they may cause damage or mistakenly be blamed for damage. Research has found that despite increases in turkey numbers and ...
