Challenging Our Conception Of Wildness, Elodie Massiot
Challenging Our Conception Of Wildness, Elodie Massiot
Animal Sentience
Baker & Winkler (2020) point out the entanglement among free-living elephants, captive elephants, and humans in the elephant tourism industry. Where all living beings – captive and free-living – are more or less affected by human presence or activity, the binary notion of wild and captive, and in situ and ex situ conservation, becomes inadequate. B&W challenge our concept of wildness – and hence of rewilding – and our level of intervention in this wildness of which we are a component.
Ecological Uncertainty Influences Vigilance As A Marker Of Fear, Laurence E. A. Feyten, Grant E. Brown
Ecological Uncertainty Influences Vigilance As A Marker Of Fear, Laurence E. A. Feyten, Grant E. Brown
Animal Sentience
We expand on the factors that may shape the predictability of risk and the potential impacts on the links between vigilance and fear, primarily in aquatic prey communities. Uncertainty in predation risks has been shown to induce increased levels of neophobia among prey. As a result of this phenotypically plastic response, prey are faced with risk assessment cues that may vary widely in their reliability. We argue that decomposing predictability may provide useful insights into the relationship between vigilance and fear.
Competing Activities As Measures Of Fear And Vigilance, Ferenc Mónus
Competing Activities As Measures Of Fear And Vigilance, Ferenc Mónus
Animal Sentience
In animal behavioural research on vigilance, visual signs of alertness are usually used to estimate perceived risk (an internal “fear” state) of free-ranging animals. Different measures of vigilance and competing activities (e.g., predator vigilance, conspecific vigilance, feeding, food handling) provide clues for better understanding vigilance behaviour. How efficiently does an animal in a vigilant/non-vigilant posture devote attention to threats or invest in other activities, such as searching for or handling food? Several species regularly withdraw to a sheltered spot when feeding in an abundant food patch, spending short periods in complete safety. Frequencies of feeding interruptions or false-alarm flights provide …
Fear And Loathing On The Landscape: What Can Foraging Theory Tell Us About Vigilance And Fear?, Burt P. Kotler, Joel S. Brown
Fear And Loathing On The Landscape: What Can Foraging Theory Tell Us About Vigilance And Fear?, Burt P. Kotler, Joel S. Brown
Animal Sentience
We discuss fear and vigilance from the perspective of foraging theory. Rather than focusing on proximate indicators of fear, we suggest that fear is an adaptation for assigning a cost to activities that incur a risk of injury or death. We use theory to provide definitions for fear and vigilance and then use that theory to compare them. We agree that there are limits to the reliability of vigilance as an indicator of fear, but we arrive at this conclusion differently.
Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown
Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown
Animal Sentience
Arguments against the fact that fish feel pain repeatedly appear even in the face of growing evidence that they do. The standards used to judge pain perception keep moving as the hurdles are repeatedly cleared by novel research findings. There is undoubtedly a vested commercial interest in proving that fish do not feel pain, so the topic has a half-life well past its due date. Key (2016) reiterates previous perspectives on this topic characterised by a black-or-white view that is based on the proposed role of the human cortex in pain perception. I argue that this is incongruent with our …
What Would The Babel Fish Say?, Monica Gagliano
What Would The Babel Fish Say?, Monica Gagliano
Animal Sentience
Starting with its title, Key’s (2016) target article advocates the view that fish do not feel pain. The author describes the neuroanatomical, physiological and behavioural conditions involved in the experience of pain in humans and rodents and confidently applies analogical arguments as though they were established facts in support of the negative conclusion about the inability of fish to feel pain. The logical reasoning, unfortunately, becomes somewhat incoherent, with the arbitrary application of the designated human criteria for an analogical argument to one animal species (e.g., rodents) but not another (fish). Research findings are reported selectively, and questionable interpretations are …

Animal Sentience
The goal of Animal Welfare Science to reduce animal suffering is commendable but too modest: Suffering animals need and deserve far more.
