Comparative Cognition And Nonhuman Individuality, Catia Correia Caeiro
Comparative Cognition And Nonhuman Individuality, Catia Correia Caeiro
Animal Sentience
Commentators Washington (2019) and Tiffin (2019) point out that the individual vs. collective dichotomy is much more complex than what is considered in the target article. This commentary will focus on why individuals are more important than collectives. Species differences in cognition and emotional processes and individuals’ feelings and experiences need to be taken into account.
Conventional Science Will Not Do Justice To Nonhuman Interests: A Fresh Approach Is Required, Becca Franks, Christine Webb, Monica Gagliano, Barbara Smuts
Conventional Science Will Not Do Justice To Nonhuman Interests: A Fresh Approach Is Required, Becca Franks, Christine Webb, Monica Gagliano, Barbara Smuts
Animal Sentience
Treves et al. (2019) make a convincing case that conservation efforts need to go beyond an anthropocentric worldview. Implementing that vision, however, will require human advocates to represent nonhuman interests. Where will the knowledge of those interests come from? How can humans know what is in the best interest of another animal, a plant, or an ecosystem? We discuss how the values embedded in current scientific practices may be ill-suited to representing nonhuman interests and we offer some ideas for correcting these shortcomings.
Preserving Nature For The Benefit Of All Sentient Individuals, Eze Paez
Preserving Nature For The Benefit Of All Sentient Individuals, Eze Paez
Animal Sentience
I agree with Treves et al.’s proposal for a preservation ethics based on the principle that nonhuman well-being is a matter of justice and compassion. In this commentary, I advance two objections. First, only sentient beings, rather than all life, belong in the moral community. Second, given that nature is probably harmful overall for sentient individuals, preserving it for the benefit of future human and nonhuman generations requires us to modify it as far as practicable.
The Wholeness Of Nature, Marthe Kiley-Worthington
The Wholeness Of Nature, Marthe Kiley-Worthington
Animal Sentience
The target article outlines various positions on conservation and preservation but ignores practical considerations of management since there is no wild habitat left. Population controls, either human or nonhuman mammals, are not discussed. The suggestions for legal changes are vague and will require much more thinking about how to integrate animal welfare with wildlife conservation concerns. “Freedoms” as outlined in the human bill of rights might help with decision making for improving animal welfare. Other commentators have made anthropocentric judgements concerning animal welfare, ignoring the importance of developing other ways of seeing and understanding the “multiplicity within unity,” combining empirical …

To represent diverse interests successfully, a strategy for dealing with conflicts is needed. We discuss an approach to maximizing the interests of the greatest number of individuals, present and future.
How To Engage Public Support To Protect Overlooked Species, Scarlett R. Howard, Adrian G. Dyer
How To Engage Public Support To Protect Overlooked Species, Scarlett R. Howard, Adrian G. Dyer
Animal Sentience
Treves et al. (2019) propose a non-anthropocentric approach to conservation biology for the ‘just preservation’ of non-humans. Some of our current ways of ranking conservation efforts based on benefits to humans are indeed critically flawed, but we doubt that a completely non-anthropocentric approach is possible at this time. We propose a way to generate public support for those non-human species that may otherwise be overlooked in policy-making and conservation efforts.
Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn
Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn
Animal Sentience
We are grateful to all the commentators who engaged with our target article. Some commentators have offered important insights into our proposed design and methods for legally intervening on behalf of futurity. Others have focused on theoretical considerations central to our proposal for multispecies justice and trusteeship. All have inspired modifications and further elaboration of our initial proposal. In this Response, we engage with the commentaries, integrating their suggestions, striving for convergence and complementarity, but also discussing points of divergence with our proposed framework where necessary. There is substantial overlap in the points of view of the three co-authors, but …
No Room For Speciesism In Welfare Considerations, Jennifer Vonk
No Room For Speciesism In Welfare Considerations, Jennifer Vonk
Animal Sentience
Speciesism should play no role in determining welfare outcomes. Cognition may vary within species as well as between species, but broad classifications such as invertebrates are functionally meaningless in this context. Cognition should relate to welfare only to the extent that it relates to the capacity to suffer or to experience pleasure.
Invertebrates Should Be Given Ethical Consideration, Marie-Claire Cammaerts
Invertebrates Should Be Given Ethical Consideration, Marie-Claire Cammaerts
Animal Sentience
Invertebrates are far more numerous than vertebrates. Most of them are essential to the survival of humanity. Their physiology, behavior, know-how, and cognitive abilities are often as complex as those of vertebrates. Invertebrates should be considered and studied as are vertebrates, i.e., ethically, and cautiously.
Intuition And The Invertebrate Dogma, Jonathan Balcombe
Intuition And The Invertebrate Dogma, Jonathan Balcombe
Animal Sentience
Just as intuition, fueled by hubris, led us to exclude insects from moral consideration, so intuition can lead to the opposite conclusion. Observed insect behavior, combined with scientific support for insect consciousness summarized in Mikhalevich & Powell’s target article, and bolstered by the Precautionary Principle, all militate against completely denying moral status to insects.
On The Possibility Of Invertebrate Sentience, David Degrazia
On The Possibility Of Invertebrate Sentience, David Degrazia
Animal Sentience
Mikhalevich & Powell (M&P) set up the basic criteria for according moral status equitably, including the capacity for affect. They argue persuasively against assuming that all invertebrates are insentient and hence ineligible for moral consideration. In addition to the relatively clear case of cephalopods, various arthropods may prove to be sentient. We should be aware of various sources of prejudice that M&P discuss and not assume that it would be absurd to attribute sentience and moral status to certain invertebrates.
Lessons From Miniature Brains: Cognition Cheap, Memory Expensive (Sentience Linked To Active Movement?), Giorgio Vallortigara
Lessons From Miniature Brains: Cognition Cheap, Memory Expensive (Sentience Linked To Active Movement?), Giorgio Vallortigara
Animal Sentience
Studies on invertebrate minds suggest that the neural machinery for basic cognition is cheap, and that bigger brains are probably associated with greater memory storage rather than more advanced cognition. Sentience may be linked to feedforward mechanisms (Reafferenzprinzip) that allow organisms with active movement to distinguish active and passive sensing. Invertebrates may offer special opportunities for testing these hypotheses.
Ethical Considerations For Invertebrates, Scarlett R. Howard, Matthew R.E. Symonds
Ethical Considerations For Invertebrates, Scarlett R. Howard, Matthew R.E. Symonds
Animal Sentience
Mikhalevich & Powell (2020) have built on the discussion about which species deserve inclusion in animal ethics and welfare considerations. Here, we raise questions concerning the assessment criteria. We ask how to assess different species for their ability to fulfill the criteria, which criteria are most important, how we quantify them (absolute or on a continuum), and how non-animals such as fungi and plants fit into this paradigm.
Functional And Whole Regression-Based Genome-Wide Association Analyses For Weightmeasurements Of Chicken Eggs, Burak Karacaören
Functional And Whole Regression-Based Genome-Wide Association Analyses For Weightmeasurements Of Chicken Eggs, Burak Karacaören
Turkish Journal of Veterinary & Animal Sciences
In genomic studies, complex traits can be modelled using repeated measures, thereby gaining a better understanding of the underlying biology. An increased number of measurements per individual might reduce measurement noise, thus increasing the likelihood of detecting true genomic signals. Here we aimed to predict genomic signals over a logistic curve referring to multiple underlying genetic architectures, for both simulated and longitudinal egg weight datasets. The chicken data were obtained from 92 sires and 801 dams of an 11th generation pure line, resulting in data from 1078 hens. We analysed longitudinal measurements of egg weights with 294,705 single nucleotide polymorphisms …

Estimation Of Genetic Parameters For Weaning Weight Of Awassi Lambs By Using Classical And Bayesian Methods, Adi̇le Tatliyer, Si̇nan Baş
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to estimate variance components and genetic parameters with six different animal models and two approaches (Bayesian and classical) on weaning weight (WW) of Awassi lambs. For this purpose, the data were obtained from Sheep and Goat Breeders' Associations of Osmaniye in Turkey. The data of 4971 progenies (from 80 rams and 1917 ewes) born between 2012 and 2016 raised under traditional conditions were evaluated. Year/season, sex, birth type, dam age, and flock size were fixed effects. All these effects except birth type were found statistically significant (P < 0.01). The overall least squares mean of weaning weight (WW) was obtained as 17.93 ± 0.05 kg. Variance components and genetic parameters were estimated by MCMC algorithms with R (for Bayesian approach) and by REML procedure with MTDFREML (for classical approach) programs. The Akaike information criterion (AIC), the log likelihood function (-2logL), and deviance information criterion (DIC) values were taken as criteria to choose the best model. Direct heritabilities of WW ranged from 0.20 to 0.35 across the models. The genetic correlation between additive genetic effect and maternal effect ranged from 0.00 to 1.00. The results were found similar across methodologies and maternal additive genetic variance resulted in lower than direct additive genetic variance. According to this study, both approaches are suitable for estimation of genetic parameters in the case of low sample size. However, the Bayesian approach, becoming increasingly popular, may be feasible to estimate variancecovariance components and genetic parameters.
