The Effects of Three Types of Environmental Enrichment on the Behaviour of Captive Javan Gibbons (Hylobates moloch)

|
by ()

This study observed the behavior of captive Javan gibbons in the UK in response to three types of environmental enrichment devices (a novel object, an olfactory and a food-based enrichment). Interest, habituation, stress, and changes in activity level were assessed to determine whether the devices could be useful to improve the quality of life of this endangered primate species when in captivity. The authors conclude that all three devices offer a form of enrichment for zoo-housed gibbons.


Functional Aspects of Emotions in Fish

| |
by ()

This article addresses the emotionality of fish, drawing upon literature from psychology, neurology and marine biology. The author discusses the definition, function, and measurement of emotion in animals and concludes that emotions in fish can be inferred, both by the similarity of their responses to those of other emotional animals, and by the functional and evolutionary advantages that emotions confer.



Project ChimpCARE: Evaluating the Care, Management, and Welfare of Privately Owned Chimpanzees in the United States

by ()

This conference presentation focused on factors that have precipitated the current situation for chimpanzees in the U.S. and Project ChimpCARE’s collaborative approach in response. The talk highlighted Project ChimpCARE’s work in quantifying the number of privately owned chimpanzees in the U.S., including those in roadside attractions and pet-breeding facilities as well as individuals kept as companion animals or used as performers. It also describes the organization’s assessment of chimpanzees’ current care and management and their efforts to work toward sustainable solutions.

The Relevance of Age and Gender for Public Attitudes to Brown Bears (Ursus arctos), Black Bears (Ursus americanus)...

by ()

Age and gender-related attitudes towards bears and cougars in Canada were explored in this study. The results showed that most participants, particularly females, feared bears and cougars and had concerns for child and adult safety. Participants were in favor of trapping and removing these animals as opposed to shooting them or tolerating their presence. The majority of participants also believed that bears and cougars serve useful functions. There were a number of age and gender-related differences in respondents’ attitudes on the topic.


Effects of Social Disruption in Elephants Persist Decades after Culling

|
by ()

This study showed differences in elephants’ core social ability based on previous experiences of social disruption. Elephants who had experienced separation from family members and relocation during culling operations in previous decades performed poorly on tests of their social knowledge, which was in sharp contrast to the well-developed social abilities of an undisturbed population of elephants. This study sheds new light on the potential long-term negative consequences of severely disruptive human activity on elephants’ key decision-making abilities, which are fundamental to their ability to function in complex societies.

Attitudes Towards Catch-and-Release Recreational Angling, Angling Practices and Perceptions of Pain and Welfare in Fish...

|
by ()

This study examined how the general public in New Zealand perceives issues of fish welfare and pain, specifically regarding catch-and-release angling. The results showed that most respondents believed that fish are capable of feeling some pain and that catch-and-release angling causes pain and compromises survival in fish. The majority of participants saw angling as an acceptable practice, though believed it is in need of guidelines and regulations to improve the welfare of fish.


Attitudes of College Undergraduates Towards Coyotes (Canis latrans) in an Urban Landscape: Management and Public Outreach...

|
by ()

This study examined attitudes towards coyotes and coyote management among college undergraduates in the Washington, D.C. metropolitan area, where coyotes are a recent addition. The survey showed a significant gap in respondents’ understanding of basic coyote biology and ecology. The study uncovered important differences between key demographic groups as well as a preference for coyote management practices that involve an action on coyotes (lethal or non-lethal) over those that restrict human behavior. The researchers also found that a fear of coyotes resulted in respondents being less likely to support the presence of coyotes and less likely to believe that guardians should be directly responsible for protecting their companion animals.

A Multiplex PCR Method to Identify Bushmeat Species in Wildlife Forensics

|
by ()

This article presents a new method for identifying the species of origin of bushmeat, i.e., meat that is illegally harvested from wild animals, often endangered species. As part of the study, the method was tested on 250 samples of bushmeat confiscated from Switzerland airports. All but one of the samples had sufficient DNA to proceed. The samples were identified as belonging to four groups: birds, fish, mammals, and reptiles. Two thirds of the samples originated from wild species, and a third of these were listed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) appendices.

Eighteen Reasons Animal Behaviourists Avoid Involvement in Conservation

|
by ()

There is frequently hesitation about applying concepts and methods of animal behavior towards solving conservation problems. This paper addresses 18 perceived impediments that may deter animal behaviorists, and provides compelling counter-arguments for each, emphasizing the relevance of animal behavior to many conservation issues. The authors call for animal behaviorists to become more involved in conservation.



Predictive Model of Avian Electrocution Risk on Overhead Power Lines

|
by ()

This research study explored factors associated with bird electrocutions by overhead power lines. The authors examined historical data from southern California to identify patterns of electrocution by voltage, month, and year, as well as at-risk species. Based on their review, they developed a predictive model that allows for the identification of poles that are likely to lead to avian electrocutions so they can be targeted for retrofitting.
