in Vitro Research Models Collection

Based on existing data and previous work, a series of studies is proposed as a basis toward a pragmatic early step in transforming toxicity testing. These studies were assembled into a data-driven framework that invokes successive tiers of testing with margin of exposure (MOE) as the primary metric. The first tier of the framework integrates data from high-throughput in vitro assays, in vitro-to-in vivo extrapolation (IVIVE) pharmacokinetic modeling, and exposure modeling. The in vitro assays are used to separate chemicals based on their relative selectivity in interacting with biological targets and identify the concentration at which these interactions …

Discrimination Of Familiar Human Faces In Dogs (Canis Familiaris), Ludwig Huber, Anaïs Racca, Billy Scaf, Zsófia Virányi, Friederike Range

Recognition Collection

Faces are an important visual category for many taxa, and the human face is no exception to this. Because faces differ in subtle ways and possess many idiosyncratic features, they provide a rich source of perceptual cues. A fair amount of those cues are learned through social interactions and are used for future identification of individual humans. These effects of individual experience can be studied particularly well in hetero-specific face perception. Domestic dogs represent a perfect model in this respect, due to their proved ability to extract important information from the human face in socio-communicative interactions. There is also …

Predator Recognition In Rainbowfish, Melanotaenia Duboulayi, Embryos, Lois J. Oulton, Vivian Haviland, Culum Brown

Aquaculture Collection

Exposure to olfactory cues during embryonic development can have long term impacts on birds and amphibians behaviour. Despite the vast literature on predator recognition and responses in fishes, few researchers have determined how fish embryos respond to predator cues. Here we exposed four-day-old rainbowfish (Melanotaenia duboulayi) embryos to cues emanating from a novel predator, a native predator and injured conspecifics. Their response was assessed by monitoring heart rate and hatch time. Results showed that embryos have an innate capacity to differentiate between cues as illustrated by faster heart rates relative to controls. The greatest increase in heart rate occurred in …

A Framework To Evaluate Wildlife Feeding In Research, Wildlife Management, Tourism And Recreation, Sara Dubois, David Fraser

Wildlife Population Management Collection

Feeding of wildlife occurs in the context of research, wildlife management, tourism and in opportunistic ways. A review of examples shows that although feeding is often motivated by good intentions, it can lead to problems of public safety and conservation and be detrimental to the welfare of the animals. Examples from British Columbia illustrate the problems (nuisance animal activity, public safety risk) and consequences (culling, translocation) that often arise from uncontrolled feeding. Three features of wildlife feeding can be distinguished: the feasibility of control, the effects on conservation and the effects on animal welfare. An evaluative framework incorporating these three …

Farm Animal Welfare Collection

In 2012, the World Organisation for Animal Health adopted 10 ‘General Principles for the Welfare of Animals in Livestock Production Systems’ to guide the development of animal welfare standards. The General Principles draw on half a century of scientific research relevant to animal welfare: (1) how genetic selection affects animal health, behaviour and temperament; (2) how the environment influences injuries and the transmission of diseases and parasites; (3) how the environment affects resting, movement and the performance of natural behaviour; (4) the management of groups to minimize conflict and allow positive social contact; (5) the effects of air quality, temperature …

Goats Favour Personal Over Social Information In An Experimental Foraging Task, Luigi Baciadonna, Alan G. Mcelligott, Elodie F. Briefer

Ethology Collection

Animals can use their environments more efficiently by selecting particular sources of information (personal or social), according to specific situations. Group-living animals may benefit from gaining information based on the behaviour of other individuals. Indeed, social information is assumed to be faster and less costly to use than personal information, thus increasing foraging efficiency. However, when food sources change seasonally or are randomly distributed, individual information may become more reliable than social information. The aim of this study was to test the use of conflicting personal versus social information in goats (Capra hircus), in a foraging task.We found that goats …

Local Attitudes Towards Bear Management After Illegal Feeding And Problem Bear Activity, Sara Dubois, David Fraser

Wildlife Population Management Collection

The “pot bears” received international media attention in 2010 after police discovered the intentional feeding of over 20 black bears during the investigation of an alleged marijuana-growing operation in Christina Lake, British Columbia, Canada. A two-phase random digit dialing survey of the community was conducted in 2011 to understand local perspectives on bear policy and management, before and after a summer of problem bear activity and government interventions. Of the 159 households surveyed in February 2011, most had neutral or positive attitudes towards bears in general, and supported the initial decision to feed the food-conditioned bears until the autumn hibernation. …

Fashion Vs. Function In Cultural Evolution: The Case Of Dog Breed Popularity, Stefano Ghirlanda, Alberto Acerbi, Harold A. Herzog, James A. Serpell

Pets Collection

We investigate the relationship between characteristics of dog breeds and their popularity between years 1926 and 2005. We consider breed health, longevity, and behavioral qualities such as aggressiveness, trainability, and fearfulness. We show that a breed’s overall popularity, fluctuations in popularity, and rates of increase and decrease around popularity peaks show typically no correlation with these breed characteristics. One exception is the finding that more popular breeds tend to suffer from more inherited disorders. Our results support the hypothesis that dog breed popularity has been primarily determined by fashion rather than function.

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

Memory Collection

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 of …

Puppy Mill Closure: The Economic Impact On A Local Community, The Humane Society Of The United States

PUPPY MILL REPORTS

When a substandard dog-breeding facility (a puppy mill) closes, removing the dogs can drain the financial resources of a community, local animal welfare entities, and large humane organizations. Towns rarely derive any benefit from puppy mills, as they employ few staff, often don’t pay required taxes or license fees, generate much animal waste and pollution, and cause unpleasant odors and noise. Once a major puppy mill enterprise is discovered, many communities don’t have the necessary resources to handle the situation. Prevention is the key, and communities should discourage large scale breeding facilities from locating in their area.

Examining The Link Between Personality And Laterality In A Feral Guppy Poecilia Reticulata Population, Eleanor Irving, Culum Brown

Sentience Collection

This study examined whether variation in the strength and direction of lateralization in a detour task was linked with variation in three common personality measurements: boldness, activity and sociability, in a population of wild guppies Poecilia reticulata. Additionally, the aim was to determine whether any consistent correlations between these behavioural traits, known as behavioural syndromes, were present in the study population. The results revealed that all three personality traits were highly repeatable over time in both sexes. Evidence of a complex syndrome in the form of a correlation between boldness, sociability and activity was found; however, this relationship was only …

Real-Time Bioacoustics Monitoring And Automated Species Identification, T. Mitchell Aide, Carlos Corrada-Bravo, Marconi Campos-Cerqueira, Carlos Milan, Giovany Vega, Rafael Alvarez

Bioacoustics Collection

Traditionally, animal species diversity and abundance is assessed using a variety of methods that are generally costly, limited in space and time, and most importantly, they rarely include a permanent record. Given the urgency of climate change and the loss of habitat, it is vital that we use new technologies to improve and expand global biodiversity monitoring to thousands of sites around the world. In this article, we describe the acoustical component of the Automated Remote Biodiversity Monitoring Network (ARBIMON), a novel combination of hardware and software for automating data acquisition, data management, and species identification based on audio recordings. …

An Hsus Report: Industrial Farm Animal Production And Livestock Associated Mrsa (Methicillin Resistant Staphylococcus Aureus), The Humane Society Of The United States

Impact of Animal Agriculture

Staphylococcus aureus is a leading cause of bacterial infection and is increasingly found to be resistant to antibiotic therapy. A newly described type of Methicillin Resistant Staphylococcus aureus carried by farm animals, Livestock Associated MRSA (LA-MRSA), is now causing infections in humans with and without direct livestock contact. A reduction in the non-therapeutic use of antibiotics in feed would likely reduce the capacity of industrial animal agriculture to continue to create, disseminate, and perpetuate a large reservoir of LA-MRSA on a global scale, but more fundamental changes in the way animals are raised for food may be necessary forestall a …

An Hsi Report: The Public Health Implications Of Intensive Farm Animal Production In South Asia, Humane Society International

HSI REPORTS

Intensive farm animal production (IFAP) is being increasingly implemented to meet the rising demand for animal source foods in South Asia. The siting of IFAP facilities in urban or peri-urban areas leads to large proximate animal populations, increasing human exposure to pollutants and pathogens. Improperly managed wastes from IFAP facilities and abattoirs can contaminate water with excess nutrients, pathogens, veterinary pharmaceuticals, antibiotics, heavy metals, and hormones, and can release ammonia, hydrogen sulfide, volatile organic compounds, bioaerosols, and particulate matter into the air compartment. The unregulated nature of IFAP in South Asia creates a risk for zoonotic transmission, including anthrax, brucellosis, …
