Modulation Of Behavior In Communicating Emotion, Martin Gardiner Jan 2016

Modulation Of Behavior In Communicating Emotion, Martin Gardiner

Animal Sentience

King discusses many examples where two animals, as they bond, behave in ways we interpret as expressing love for one another. If one of the bonded animals then dies, signs of loving are replaced by signs we interpret as expressing grief by the animal who remains. I propose a pathway for emotional communication between an animal and an observer that can have a central role in these and other observations by King and in our overall ability to interpret observed behavior in relation to emotion. This pathway provides evidence of emotion in an observed animal by communicating evidence of emotion’s …

Leaving The Door Open For Fish Pain: Evolutionary Convergence And The Utility Of ‘Just-So Stories’, David B. Edelman Jan 2016

Leaving The Door Open For Fish Pain: Evolutionary Convergence And The Utility Of ‘Just-So Stories’, David B. Edelman

Animal Sentience

Key argues that fish do not experience pain because they lack the necessary (but not necessarily sufficient) brain structures and associated functional circuitry to engender such conscious percepts. I propose that fish pain may be dependent on neuroanatomical regions and pathways that are structurally and/or functionally analogous — but not strictly homologous — to well-characterized mammalian substrates of pain. An example is the convergent appearance of the complex, single-compartment eye across invertebrate and vertebrate phylogeny. Structural-functional convergence is ubiquitous in evolution. Comparative inferences and correlative lines of evidence play an important role in building evolutionary arguments. The dismissal of the …

Spinning Our Wheels And Deepening The Divide: Call For An Evidence-Based Approach To The Fish Pain Debate, Steven J. Cooke Jan 2016

Spinning Our Wheels And Deepening The Divide: Call For An Evidence-Based Approach To The Fish Pain Debate, Steven J. Cooke

Animal Sentience

There is vigorous ongoing debate about whether fish feel pain and have the capacity to suffer. The body of literature dedicated to the topic is increasing but what is particularly problematic is that the majority of the contributions represent opinion pieces and thus fall within the realm of advocacy. Many of the empirical research papers purporting that fish do or do not feel pain have problems with cavalier use of definitions, poor experimental design, or statistical/technical issues and tend to include advocacy statements in their interpretations. Rather than continuing to spin our wheels and deepen the divide, I would advocate …

How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng Jan 2016

How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng

Animal Sentience

Welfare biology is the study of the welfare of living things. Welfare is net happiness (enjoyment minus suffering). Since this necessarily involves feelings, Dawkins (2014) has suggested that animal welfare science may face a paradox, because feelings are very difficult to study. The following paper provides an explanation for how welfare biology could help to reduce this paradox by answering some difficult questions regarding animal welfare. Simple means based on commonsense could reduce animal suffering enormously at low or even negative costs to humans. Ways to increase the influence of animal welfare advocates are also discussed, focusing initially on farmed …

End-State Welfarism, Joel Marks Jan 2016

End-State Welfarism, Joel Marks

Animal Sentience

Yew-Kwang Ng’s research is the work of an obviously sincere, intelligent, and conscientious animal advocate. But I am unable to accept his starting assumption that animal welfare is an appropriate basis for animal ethics. More specifically I argue that animal welfare as a means to animal liberation is an issue that can be debated, but animal welfare as the ultimate end or goal of animal advocacy is misguided.

Animal Suffering Calls For More Than A Bigger Cage, Simon R. B. Leadbeater Jan 2016

Animal Suffering Calls For More Than A Bigger Cage, Simon R. B. Leadbeater

Animal Sentience

Ng (2016) argues for incremental welfare biology partly because it would be impossible to demonstrate conclusively that animals are sentient. He argues that low cost changes in industrial practices and working collaboratively may be more effective in advancing animal welfare than more adversarial approaches. There is merit in some of Ng’s recommendations but a number of his arguments are, in my view, misdirected. The fact that nonhuman animals feel has already been adequately demonstrated. Cruelty to animals is intrinsic to some industries, so the only way to oppose it is to oppose the industry.

Dung Beetles (Coleoptera: Scarabaeidae) Utilizing Water Buffalo Dungon The Black Sea Coast Of Turkey, Gregory Thomas Sullivan, Sebahat Sullivan, Jean-Pierre Lumaret, Greg Baxter, Myron Zalucki, Ünal Zeybekoğlu

Turkish Journal of Zoology

There have been few ecological studies of dung beetles (Coleoptera: Scarabaeidae) from the Black Sea Region of Turkey. In the RAMSAR-listed wetland system of the Kızılırmak Delta of Turkey's central Black Sea coast, seasonal grazing by domesticated water buffalo produces plentiful dung from April to November. Twenty-three species of dung beetles from 13 genera of Aphodiinae and 4 genera of Scarabaeinae were collected from their dung on two adjacent soil types in 2013. The species were from three functional groups, namely dung dwelling (12), tunneling (10), and ball rolling (1). Thirteen and fourteen species were collected in spring/summer and autumn, …

Morphological Characteristics Of The Elusive Blotched Snake (Elaphe Sauromates)At Its Northwestern Range Limit (Romania), Tiberiu Sahlean, Alexandru Strugariu, Paul Dinca, Gabriel Chişamera, Catalin Stanciu, Ştefan Zamfirescu, Iulian Gherghel, Valentina Moraru

Turkish Journal of Zoology

The blotched snake (Elaphe sauromates) is one of the most elusive species of snakes in Romania, and only a small number of individuals have ever been found, which is why morphological data are both scarce and over half a century old. The data gathered from the individuals captured during our field work confirmed the presence of sexual dimorphism (significant for SVL/TL ratios) and presented a greater morphological variation than recorded in the scientific literature. Individuals examined usually had more than 2 rows of temporal scales and displayed variation in subocular scales, as opposed to the information previously available, hinting at …

First Record Of The Invasive Vinegar Fly Drosophila Suzukii (Matsumura)(Diptera: Drosophilidae) From Eastern Turkey, Alper Orhan, Rafet Aslantaş, Banu Şebnem Önder, Göksel Tozlu Jan 2016

First Record Of The Invasive Vinegar Fly Drosophila Suzukii (Matsumura)(Diptera: Drosophilidae) From Eastern Turkey, Alper Orhan, Rafet Aslantaş, Banu Şebnem Önder, Göksel Tozlu

Turkish Journal of Zoology

Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) is native to East Asia and invasive on the European and American continents. The first records in both Europe and the United States were in 2008. Since that year, it has widely moved across these continents. As D. Suzukii females lay eggs in healthy ripening fruits of several species, particularly in small soft fruits and berries, the species causes agricultural damage. The soft thin-skinned fruit pest, identified as D. Suzukii, has been found in Erzurum, Turkey, where damaged strawberry crops were observed and cultured in the middle of August and September 2014. Initially, 2 …

Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom Jan 2016

Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom

Animal Sentience

The concept of sentience concerns the capacity to have feelings. There is evidence for sophisticated cognitive concepts and for both positive and negative feelings in a wide range of nonhuman animals. All vertebrates, including fish, as well as some molluscs and decapod crustaceans have pain systems. Most people today consider that their moral obligations extend to many animal species. Moral decisions about abortion, euthanasia, and the various ways we protect animals should take into account the research findings about sentience. In addition, all animal life should be respected and studies of the welfare of even the simplest invertebrate animals should …

Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke Jan 2016

Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke

Animal Sentience

Broom’s (2014) book is a well-researched and thoroughly written exploration and evaluation of the journey from the origins of animal welfare science to what we can say we now know and need to consider in relation to animal sentience and welfare. This book will help to counter any skepticism among academics and policy makers.

Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan Jan 2016

Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan

Animal Sentience

According to Broom (2014), animal welfare is a concept that can be applied to all animals, including single-celled organisms that are obviously not sentient. Such a stance makes it difficult to draw a connection between welfare and sentience, and that is the book’s downfall. Some excellent points are made about sentience and there are very good discussions on animal welfare. However, unless sentience is considered the essential component of welfare, any attempt to link the two phenomena will be unsuccessful — and that, indeed, is the case with this book.

Sentience And Animal Welfare: New Thoughts And Controversies, Donald M. Broom Jan 2016

Sentience And Animal Welfare: New Thoughts And Controversies, Donald M. Broom

Animal Sentience

Sentience involves having some degree of awareness but awareness of self is not as complex as some people believe. Fully functioning vertebrate animals, and some invertebrates, are sentient but neither humans nor non-humans are sentient early in development or if brain-damaged. Feelings are valuable adaptive mechanisms and an important part of welfare but are not all of welfare so the term welfare refers to all animals, not just to sentient animals. We have much to learn about what non-human animals want from us, the functioning of the more complex aspects of their brains and of our brains and how we …

Pain And Fish Welfare, Eliane Gonçalves-De-Freitas Jan 2016

Pain And Fish Welfare, Eliane Gonçalves-De-Freitas

Animal Sentience

The evolutionary approach of Key’s (2016) target article, generically comparing humans with fish of all kinds, is simplistic. The author ignores published research on structural and molecular aspects of pain in fish. The target article reads more like a selective polemic against fish welfare than an even-handed analysis.

Brain Processes For “Good” And “Bad” Feelings: How Far Back In Evolution?, Jaak Panksepp Jan 2016

Brain Processes For “Good” And “Bad” Feelings: How Far Back In Evolution?, Jaak Panksepp

Animal Sentience

The question of whether fish can experience pain or any other feelings can only be resolved by neurobiologically targeted experiments. This commentary summarizes why this is essential for resolving scientific debates about consciousness in other animals, and offers specific experiments that need to be done: (i) those that evaluate the rewarding and punishing effects of specific brain regions and systems (for instance, with deep-brain stimulation); (ii) those that evaluate the capacity of animals to regulate their affective states; and (iii) those that have direct implications for human affective feelings, with specific predictions — for instance, the development of new treatments …

Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen Dec 2015

Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen

Western North American Naturalist

In the northern U.S. Rockies, including the Greater Yellowstone Ecosystem (GYE), connectivity is a concern because large carnivores have difficulties dispersing successfully between protected areas. One area of high conservation value because of its importance for connecting the GYE to wilderness areas of central Idaho is the Centennial Mountains and surrounding valleys (2500 km2) along the Idaho–Montana border just west of Yellowstone National Park. The current expansion of grizzly bears (Ursus arctos) and other large carnivore populations outside protected areas of Yellowstone National Park and Grand Teton National Park has placed a greater emphasis on potential linkage zones …
