Environmental Impacts Of One Puppy Mill Among Many: A Case History, John A. Gill
Environmental Impacts Of One Puppy Mill Among Many: A Case History, John A. Gill
Puppy Mills Collection
In recent decades, the animal welfare aspects of irresponsibly-managed commercial dog-breeding businesses have attracted national attention, prompting legislative and regulatory actions. However, the environmental impacts of such businesses, also known as puppy mills, have received far less attention. Most puppy mills are secretive; therefore, it is hard to get documented information about their environmental impacts. Although the former Whispering Oaks Kennels near Parkersburg, W.Va., also kept secrets, reliable environmental information regarding its operation became available because in the summer of 2008, Wood County cited the facility for violating the State’s water pollution and solid waste statutes. This report is based …
Can Acute Dermal Systemic Toxicity Tests Be Replaced With Oral Tests? A Comparison Of Route-Specific Systemic Toxicity And Hazard Classifications Under The Globally Harmonized System Of Classification And Labelling Of Chemicals (Ghs), Nigel P. Moore, David J.

Can Acute Dermal Systemic Toxicity Tests Be Replaced With Oral Tests? A Comparison Of Route-Specific Systemic Toxicity And Hazard Classifications Under The Globally Harmonized System Of Classification And Labelling Of Chemicals (Ghs), Nigel P. Moore, David J. Andrew, Donald L. Bjerke, Stuart Creton, David Dreher, Thomas Holmes, Pilar Prieto, Troy Seidle, Tim G. Rowan
Experimentation Collection
Acute systemic toxicity data (LD50 values) and hazard classifications derived in the rat following oral administration and dermal application have been analysed to examine whether or not orally-derived hazard classification or LD50 values can be used to determine dermal hazard classification. Comparing the oral and dermal classifications for 335 substances derived from oral and dermal LD50 values respectively revealed 17% concordance, and indicated that 7% of substances would be classified less severely while 76% would be classified more severely if oral classifications were applied directly to the dermal route. In contrast, applying the oral LD50 values within the dermal classification …
Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Sentience Collection
Moods influence cognitive processes in that people in positive moods expect more positive events to occur and less negative ones (“optimistic bias”), whereas the opposite happens for people in negative moods (“pessimistic bias”). The evidence for an effect of mood on cognitive bias is also increasing in animals, suggesting that measures of optimism and pessimism could provide useful indicators of animal welfare. For obvious ethical reasons, serious poor treatments cannot be easily replicated in large mammals in order to study their long-term effects on moods. In this study, we tested the long-term effects (>2 years) of prior poor welfare …

Environmental Change Alters Personality In The Rainbow Trout, Oncorhynchus Mykiss, Ashley J. Frost, Jack S. Thomson, Charlotte Smith, Hannah C. Burton, Ben Davis, Phillip C. Watts, Lynne U. Sneddon
Sentience Collection
Boldness is a personality trait that defines how individuals respond to risky situations and has clear fitness consequences. Since the adaptive value of boldness is context dependent, the benefit of a distinct personality is less clear when the environment is unpredictable. An ability to modulate behaviour can be beneficial, although as behavioural plasticity itself may be costly this depends on the levels of environmental stability. Both boldness and its plasticity are linked with physiological stress coping mechanisms, whereby animals with reduced glucocorticoid responses to stress are bolder and less flexible in behaviour. We investigated the behavioural changes made by bold …
Site Fidelity And Homing Behaviour In Intertidal Fishes, Gemma E. White, Culum Brown
Site Fidelity And Homing Behaviour In Intertidal Fishes, Gemma E. White, Culum Brown
Sentience Collection
The theory of ecological cognition poses that the brains and behaviour of animals are shaped by the environmental challenges they face in their everyday lives. Site fidelity and homing ability was tested for five species of intertidal rock pool fish by tagging and displacing them to new rock pools at various distances from their ‘home’ rock pools. Three of the species were rock pool specialists whilst the remaining two spend a small proportion of their life in rock pools during early ontogeny. The three specialists showed strong site fidelity with >50 % of individuals found in the same pool 42 …
Are Juvenile Domestic Pigs (Sus Scrofa Domestica) Sensitive To The Attentive States Of Humans? The Impact Of Impulsivity On Choice Behaviour, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell
Are Juvenile Domestic Pigs (Sus Scrofa Domestica) Sensitive To The Attentive States Of Humans? The Impact Of Impulsivity On Choice Behaviour, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell
Attention Collection
Previous studies have shown that apes, dogs and horses seem to be able to attribute attentive states to humans. Subjects chose successfully between two persons: one who was able to see the animal and one who was not. Using a similar paradigm, we tested a species that does not rely strongly on visual cues, the domestic pig (Sus scrofa domestica). Subjects could choose between two unfamiliar persons, with only one showing attention, in three different conditions (body, head away, body turned - head front). Subjects (n = 16) only showed a tendency towards …
Marine Invertebrates: Communities At Risk, Jennifer A. Mather
Marine Invertebrates: Communities At Risk, Jennifer A. Mather
Ecological Impacts of Climate Change Collection
Our definition of the word ‘animal’ centers on vertebrates, yet 99% of the animals on the planet are invertebrates, about which we know little. In addition, although the Census of Marine Life (COML.org) has recently conducted an extensive audit of marine ecosystems, we still do not understand much about the animals of the seas. Surveys of the best-known ecosystems, in which invertebrate populations often play a key role, show that the invertebrate populations are affected by human impact. Coral animals are the foundation of coral reef systems, which are estimated to contain 30% of the species in the ocean. Physical …
Estimating Animal Population Density Using Passive Acoustics, Tiago A. Marques, Len Thomas, Stephen W. Martin, David K. Mellinger, Jessica A. Ward, Danielle Harris, Peter L. Tyack
Estimating Animal Population Density Using Passive Acoustics, Tiago A. Marques, Len Thomas, Stephen W. Martin, David K. Mellinger, Jessica A. Ward, Danielle Harris, Peter L. Tyack
Bioacoustics Collection
Reliable estimation of the size or density of wild animal populations is very important for effective wildlife management, conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from transect lines or some form of capture-recapture on marked or uniquely identifiable individuals. However, many species are difficult to sight, and cannot be easily marked or recaptured. Some of these species produce readily identifiable sounds, providing an opportunity to use passive acoustic data to estimate animal density. In addition, even for species for which other visually based methods are feasible, passive acoustic methods offer …
Fallow Deer Polyandry Is Related To Fertilization Insurance, Elodie F. Briefer, Mary E. Farrell, Thomas J. Hayden, Alan G. Mcelligott
Fallow Deer Polyandry Is Related To Fertilization Insurance, Elodie F. Briefer, Mary E. Farrell, Thomas J. Hayden, Alan G. Mcelligott
Ethology Collection
Polyandry is widespread, but its adaptive significance is not fully understood. The hypotheses used to explain its persistence have rarely been tested in the wild and particularly for large, long-lived mammals. We investigated polyandry in fallow deer, using female mating and reproduction data gathered over 10 years. Females of this species produce a single offspring (monotocous) and can live to 23 years old. Overall, polyandry was evident in 12 % of females and the long-term, consistent proportion of polyandrous females observed, suggests that monandry and polyandry represent alternative mating strategies. Females were more likely to be polyandrous when their first …
Inflammatory Findings On Species Extrapolations: Humans Are Definitely No 70-Kg Mice, Marcel Leist, Thomas Hartung
Inflammatory Findings On Species Extrapolations: Humans Are Definitely No 70-Kg Mice, Marcel Leist, Thomas Hartung
Validation of Alternative Methods Collection
Modern toxicology has embraced in vitro methods, and major hopes are based on the Omics technologies and systems biology approaches they bring along (Hartung and McBride in ALTEX 28(2):83–93, 2011; Hartung et al. in ALTEX 29(2):119–28, 2012). A culture of stringent validation has been developed for such approaches (Leist et al. in ALTEX 27(4):309–317, 2010; ALTEX 29(4):373–88, 2012a; Toxicol Res 1:8–22, 2012b), while the quality and usefulness of animal experiments have been little scrutinized. A new study (Seok et al. 2013) now shows the low predictivity of animal responses in the field of inflammation. These findings corroborate earlier findings from …
A Study Of Sharing And Reciprocity In Grey Parrots (Psittacus Erithacus), Franck Péron, Maria John, Stephanie Sapowicz, Dalila Bovet, Irene M. Pepperberg
A Study Of Sharing And Reciprocity In Grey Parrots (Psittacus Erithacus), Franck Péron, Maria John, Stephanie Sapowicz, Dalila Bovet, Irene M. Pepperberg
Sentience Collection
Demonstrations of nonhuman ability to share resources and reciprocate such sharing seem contingent upon the experimental paradigm used (note Horner et al. in PNAS 108:13847–13851, 2011). Here, such behaviour in Grey parrots (Psittacus erithacus) was tested in two experiments, both designed to avoid possible issues involving apparatus complexity, visible reward options, and physical competition and/or limited communication between subjects. In both studies, two birds, working in dyads, took turns in choosing one of four different coloured cups with differing outcomes: empty (null, nonrewarding), selfish (keeping reward for oneself), share (sharing a divisible reward), or giving (donating reward to other). In …
Application Of Qualitative Behavioural Assessment To Horses During An Endurance Ride, Patricia A. Fleming, Cheree L. Paisley, Anne L. Barnes, Françoise Wemelsfelder
Application Of Qualitative Behavioural Assessment To Horses During An Endurance Ride, Patricia A. Fleming, Cheree L. Paisley, Anne L. Barnes, Françoise Wemelsfelder
Sentience Collection
Endurance horses are considered subject to a unique set of training and competing pressures due to the long distances travelled. The health and welfare of these horses could be compromised if they have not been adequately trained or are pushed beyond their limits, and there are increasing concerns regarding the capacity of horses to cope with the exercise demands placed on them, with high elimination rates for lameness and metabolic reasons. Veterinary inspections during these rides are important for assessing physiological measures, but the inclusion of behavioural assessments is also warranted. We investigated the application of Qualitative Behavioural Assessment (QBA) …

Inter-Observer Reliability Of Qualitative Behavioural Assessments Of Sheep, Clare Phythian, Eleni Michalopoulou, Jennifer Duncan, Françoise Wemelsfelder
Sentience Collection
Qualitative Behaviour Assessment (QBA) is whole-animal methodology that assesses the expressive qualities of animal demeanour using descriptors such as ‘relaxed’, ‘anxious’ or ‘content’. This study aimed to examine the inter-observer reliability of 12 fixed-list QBA descriptors for sheep that had been generated in a previous Free-Choice Profiling study by experienced animal welfare inspectors, based on the same video footage used in the current study. The 12 QBA terms were scored by two different assessor groups consisting of two veterinary science students and four veterinary surgeons (Group 1), and seven farm assurance inspectors (Group 2). The two assessor groups met and …
Neutering Dogs: Effects On Joint Disorders And Cancers In Golden Retrievers, Gretel Torres De La Riva, Benjamin L. Hart, Thomas B. Farver, Anita M. Oberbauer, Locksley L. Mcv Messam, Neil H. Willits, Lynette A. Hart
Neutering Dogs: Effects On Joint Disorders And Cancers In Golden Retrievers, Gretel Torres De La Riva, Benjamin L. Hart, Thomas B. Farver, Anita M. Oberbauer, Locksley L. Mcv Messam, Neil H. Willits, Lynette A. Hart
Endocrinology Collection
In contrast to European countries, the overwhelming majority of dogs in the U.S. are neutered (including spaying), usually done before one year of age. Given the importance of gonadal hormones in growth and development, this cultural contrast invites an analysis of the multiple organ systems that may be adversely affected by neutering. Using a single breed-specific dataset, the objective was to examine the variables of gender and age at the time of neutering versus leaving dogs gonadally intact, on all diseases occurring with sufficient frequency for statistical analyses. Given its popularity and vulnerability to various cancers and joint disorders, the …
Pattern Of Social Interactions After Group Integration: A Possibility To Keep Stallions In Group, Sabrina Briefer Freymond, Elodie F. Briefer, Rudolf Von Niederhäusern, Iris Bachmann
Pattern Of Social Interactions After Group Integration: A Possibility To Keep Stallions In Group, Sabrina Briefer Freymond, Elodie F. Briefer, Rudolf Von Niederhäusern, Iris Bachmann
Ethology Collection
Horses are often kept in individual stables, rather than in outdoor groups, despite such housing system fulfilling many of their welfare needs, such as the access to social partners. Keeping domestic stallions in outdoor groups would mimic bachelor bands that are found in the wild. Unfortunately, the high level of aggression that unfamiliar stallions display when they first encounter each other discourages owners from keeping them in groups. However, this level of aggression is likely to be particularly important only during group integration, when the dominance hierarchy is being established, whereas relatively low aggression rates have been observed among stable …
Evolutionary Responses To Invasion: Cane Toad Sympatric Fish Show Enhanced Avoidance Learning, Georgina Caller, Culum Brown
Evolutionary Responses To Invasion: Cane Toad Sympatric Fish Show Enhanced Avoidance Learning, Georgina Caller, Culum Brown
Aquaculture Collection
The introduced cane toad (Bufo marinus) poses a major threat to biodiversity due to its lifelong toxicity. Several terrestrial native Australian vertebrates are adapting to the cane toad’s presence and lab trials have demonstrated that repeated exposure to B. marinus can result in learnt avoidance behaviour. Here we investigated whether aversion learning is occurring in aquatic ecosystems by comparing cane toad naı¨ve and sympatric populations of crimson spotted rainbow fish (Melanotaenia duboulayi). The first experiment indicated that fish from the sympatric population had pre-existing aversion to attacking cane toad tadpoles but also showed reduced attacks on native tadpoles. The second …
Explaining China’S Wildlife Crisis: Cultural Tradition Or Politics Of Development, Peter J. Li
Explaining China’S Wildlife Crisis: Cultural Tradition Or Politics Of Development, Peter J. Li
Threatened and Endangered Animal Populations Collection
This chapter is about China’s wildlife crisis. As the following sections attempt to demonstrate, abuse of and assault on wildlife in captivity and in the wild have reached an unprecedented level on the Chinese mainland in the reform era (1978–present). Shocking brutality against wildlife animals has been frequently exposed by Chinese and international media. To readers outside East Asia, they ask if the Chinese are culturally indifferent to animal suffering. Indeed, does the Chinese culture sanction cruelty to animals? Or is it the contemporary politics of economic development that is more directly responsible for the crisis?
The Applicability Of The Self-Fulfillment Account Of Welfare To Nonhuman Animals, Babies, And Mentally Disabled Humans, Tatjana Visak, Jonathan Balcombe
The Applicability Of The Self-Fulfillment Account Of Welfare To Nonhuman Animals, Babies, And Mentally Disabled Humans, Tatjana Visak, Jonathan Balcombe
Sentience Collection
In this paper we will argue that generality is a virtue of Haybron’s account of welfare. Indeed, reflecting on the applicability of his theory to nonhuman animals will give us a better understanding of its applicability to humans. We will first focus on self-fulfillment and suggest an interpretation of Haybron’s account according to which the self-fulfillment of an individual consists in the fulfillment of the aspects of the self that are applicable to that particular individual. This makes Haybron’s account of welfare applicable to all sentient beings. Then we will focus on sub-personal nature-fulfillment and argue that the same interpretation …
Prolonged Pain Research In Mice: Trends In Reference To The 3rs, Jonathan Balcombe, Hope Ferdowsian, Lauren Briese
Prolonged Pain Research In Mice: Trends In Reference To The 3rs, Jonathan Balcombe, Hope Ferdowsian, Lauren Briese
Experimentation Collection
This literature review documents trends in the use of mice in prolonged pain research, defined herein as research that subjects mice to a source of pain for at least 14 days. The total amount of prolonged pain research on mice has increased dramatically in the past decade for the 3 pain categories examined: neuropathic, inflammatory, and chronic pain. There has also been a significant rise in the number of prolonged mouse pain studies as a proportion of all mouse studies and of all mouse pain studies. The use of transgenic mice has also risen significantly in prolonged pain research, though …
Environmental Impacts Of Puppy Mills, The Humane Society Of The United States
Environmental Impacts Of Puppy Mills, The Humane Society Of The United States
PUPPY MILL REPORTS
A puppy mill is “a dog breeding operation in which the health of the dogs is disregarded in order to maintain a low overhead and maximize profits.” Avenson v. Zegart, 577 F. Supp. 958, Dist. Court, Minnesota (1984). State and federal inspection reports reveal that a common method employed to maximize profits includes irresponsible waste management practices that are harmful to the environment. Impacts may be caused by improper disposal of feces, urine and carcasses.

The Research & Toxicology Department of Humane Society International (HSI) operates a multifaceted and science-driven global programme aimed at ending the use of animals in toxicity testing and research. The key strategic objectives include: a) ending cosmetics animal testing worldwide, via the multinational Be Cruelty-Free campaign; b) achieving near-term reductions in animal testing requirements through revision of product sector regulations; and c) advancing humane science by exposing failing animal models of human disease and shifting science funding toward human biology-based research and testing tools fit for the 21st century. HSI was instrumental in ensuring the implementation of the March 2013 …
A Vision Becoming Reality, Gill Langley
A Vision Becoming Reality, Gill Langley
Laboratory Experiments Collection
Non-animal science in toxicology and health research has been progressing for decades, but only now is it being seen widely as advanced science. The emergence of novel human biology-based tools and models, combined with legislative and regulatory change, a 21st century concept for toxicology, continuing failures in the drug pipeline, and systematic critiques of animal models, have created a pivotal moment of change. The leading edge is starting to become the norm. Humans and other animals are likely to benefit as a result.
Great Ape Mindreading: What’S At Stake?, Kristin Andrews
Great Ape Mindreading: What’S At Stake?, Kristin Andrews
Ethology Collection
Humans and other great apes are similar in so many ways. We share an extended immaturity and intense infant-caregiver relationships, group living situations, cultural transmission of technology, and many emotions and cognitive capacities. Yet the communities of nonhuman apes are also very different from human communities. Humans build lasting tools, and store them to use later. We build permanent sleeping and living structures. We cook our food. We have courts of law and prisons and ethics books. There are vast technological differences between humans and nonhuman great apes. What is it that accounts for such a difference? On one account, …
Are Apes’ Responses To Pointing Gestures Intentional?, Olivia Sultanescu, Kristin Andrews
Are Apes’ Responses To Pointing Gestures Intentional?, Olivia Sultanescu, Kristin Andrews
Sentience Collection
This paper examines the meaningfulness of pointing in great apes. We appeal to Hannah Ginsborg’s conception of primitive normativity, which provides an adequate criterion for establishing whether a response is meaningful, and we attempt to make room for a conception according to which there is no fundamental difference between the responses of human infants and those of other great apes to pointing gestures. This conception is an alternative to Tomasello’s view that pointing gestures and reactions to them reveal a fundamental difference between humans and other apes.

Social Learning In Juvenile Lemon Sharks, Negaprion Brevirostris, Tristan L. Guttridge, Sander Van Dijk, Eize Stamhuis, Jens Krause, Samuel Gruber, Culum Brown
Sentience Collection
Social learning is taxonomically widespread and can provide distinct behavioural advantages, such as in finding food or avoiding predators more efficiently. Although extensively studied in bony fishes, no such empirical evidence exists for cartilaginous fishes. Our aim in this study was to experimentally investigate the social learning capabilities of juvenile lemon sharks, Negaprion brevirostris. We designed a novel food task, where sharks were required to enter a start zone and subsequently make physical contact with a target in order to receive a food reward. Naive sharks were then able to interact with and observe (a) pre-trained sharks, that is, ‘demonstrators’, …

Food For Thought … Mechanistic Validation, Thomas Hartung, Sebastian Hoffman, Martin Stephens
Experimentation Collection
Validation of new approaches in regulatory toxicology is commonly defined as the independent assessment of the reproducibility and relevance (the scientific basis and predictive capacity) of a test for a particular purpose. In large ring trials, the emphasis to date has been mainly on reproducibility and predictive capacity (comparison to the traditional test) with less attention given to the scientific or mechanistic basis. Assessing predictive capacity is difficult for novel approaches (which are based on mechanism), such as pathways of toxicity or the complex networks within the organism (systems toxicology). This is highly relevant for implementing Toxicology for the 21st …
Does True Syntax Or Simple Auditory Object Support The Role Of Skylark Song Dialect?, Elodie F. Briefer, Fanny Rybak, Thierry Aubin
Does True Syntax Or Simple Auditory Object Support The Role Of Skylark Song Dialect?, Elodie F. Briefer, Fanny Rybak, Thierry Aubin
Sentience Collection
Parallels between birdsong and human language are numerous and include particular temporal arrangements of acoustic units and the existence of dialects. In animal communication, modifications of the temporal ordering of existing acoustic units have rarely been clearly linked with changes in information content, particularly in a natural environment. Here, we show that the organization of birdsong units (‘syllables’) in sequences supports interindividual relationships within skylark communities. We manipulated the temporal arrangement of song dialect variants (‘shared phrases’) in the skylark, Alauda arvensis, a songbird with a very large repertoire of syllables and complex song. When tested with playback experiments performed …
Identification Of The Rainbowfish In Lake Eacham Using Dna Sequencing, Culum Brown, Yagiz Aksoy, Hilal Varinli, Michael Gillings
Identification Of The Rainbowfish In Lake Eacham Using Dna Sequencing, Culum Brown, Yagiz Aksoy, Hilal Varinli, Michael Gillings
Veterinary Science and Medicine Collection
The Lake Eacham rainbowfish (Melanotaenia eachamensis) was once thought to be confined to its type locality within the Lake Eacham World Heritage National Park. M. eachamensis disappeared from the lake following the translocation of several species into the lake and the species was pronounced extinct in the wild in 1987. In a 2007 survey we noticed that rainbowfish were present in the lake once again. We used a molecular marker to identify these fish and the likely source population. Analysis of the D-loop region of mitochondrial DNA revealed that the species now present in the lake is Melanotaenia splendida, and …
