The impact of care on chimpanzee welfare: A comprehensive review

Animal welfare research has increased dramatically in scope and prevalence, spanning zoos, aquariums, sanctuaries, and research facilities. Chimpanzees are the most common and well-studied great ape living in human care. This considerable focus on chimpanzee welfare provides the foundation for...

A new laboratory research model: The Damaraland mole-rat and its managed care

The Damaraland mole-rat (Fukomys damarensis) is a subterranean, hypoxia-tolerant, long-lived rodent endemic to southern and central Africa that is increasingly being used in laboratory research. Its husbandry needs and characteristics differ from traditional rodent research models. Here, we provide a...

How much “enrichment” is enough for laboratory rodents? A systematic review and meta-analysis re-assessing the impact of well-resourced cages on morbidity and mortality

Laboratory rodent housing often fails to meet rodents' behavioral and physiological needs. We previously found that compared to well-resourced (often called 'enriched') housing, conventional cages increase mortality rates and the morbidity of stress-sensitive experimentally-induced diseases (anxiety, cancer, cardiovascular disease, depression,...

Effects of simple cage enrichment and its removal on the behavior and welfare of American mink (Neogale vison)

Environmental enrichment may reduce stereotypies in fur-farmed mink. North American mink standards require manipulable enrichment objects within cages. However, mink can rapidly destroy objects inhibiting continuous enrichment presence, which may have negative welfare impacts. This experimental study determined the effects...

The lasting impact of social isolation: Behavioral insights from former pet and entertainer chimpanzees in a sanctuary in Spain

Human fascination with chimpanzees has driven extensive research on the species, but also led to exploitation by private owners and entertainment industries. These animals often suffer species-specific inadequate conditions, which can result in the development and display of abnormal behaviors...

Murine model of minimally invasive nasal depot (MIND) technique for central nervous system delivery of blood–brain barrier-impermeant therapeutics

The blood–brain barrier (BBB) poses a substantial obstacle to the successful delivery of therapeutics to the central nervous system (CNS). The transnasal route has been extensively explored, but success rates have been modest due to challenges related to the precise...

Evidence of stable preferential affiliative relationships in the domestic pig

Affiliative relationships are well documented in a wide range of wild animals. However, there is limited evidence of their existence in social farm animals, despite potential significant animal welfare implications. We aimed to determine whether pigs have preferential partners for...

Maned wolves (Chrysocyon brachyurus) differ in their responses to environmental enrichment: Why? Applied Animal Behaviour Science 280, 106432

The maned wolf, a species vulnerable to extinction, is widely found in zoos. Environmental enrichment techniques have been recommended to increase environmental unpredictability, therefore stimulating behavioral diversity, and promoting welfare for zoo animals. However, diverse responses to unpredictability have been...

Are you serious? Relaxed open mouth may unveil the competitive/cooperative nature of play fighting in two feline species

Play fighting is a multifunctional behaviour allowing the development of both cooperative and competitive skills. During play fighting, animals perform ‘competitive' actions that are typical of the agonistic context and/or ‘cooperative' actions to avoid escalation into aggression. Several structural features...

Salivary cortisol captures endocrine response to an acute stressor in captive female tufted capuchin monkeys (Sapajus apella)

Measuring glucocorticoids such as cortisol is a useful tool for exploring relationships among behavior, physiology, and well-being in primates. As cortisol circulates in blood, it moves into biological matrices such as hair, urine, feces, and saliva. Saliva sampling is a...
