Reef Society And The Tyranny Of Data, Robert Wintner

Animal Sentience

Modern science now approaches divergent processes in many areas, including health assessments of marine eco-systems and social aspects of marine species. Scientific data have long enjoyed a reputation for objectivity but incidents of science-for-hire, data spinning/skewing and political jading are more frequent than ever. In the field of reef creature sensitivity, technical treatises can “logically” explain away what a person of average education can clearly observe on any given reef. Western medicine discounted anecdotal evidence of any cure outside the 4% margin of error until those cures demanded attention and in some cases application. Modern science must now enter an …

Still Wondering How Flesh Can Feel, Gwen J. Broude

Animal Sentience

Reber believes he has simplified Chalmers’s “hard problem” of consciousness by arguing that subjectivity is an inherent feature of biological forms. His argument rests on the related notions of continuity of mind and gradual accretion of capacities across evolutionary time. These notions need to be defended, not just asserted. Because Reber minimizes the differences in mental faculties among species across evolutionary time, it becomes easier to assert, and perhaps believe, that sentience is already present in early biological forms. The more explicit we are about the differences among these mental faculties and the differences across species, the less persuasive is …

Integrating Habitat Suitability Modeling And Radio Telemetry To Describe Habitat Use Of The Western Massasaugas, Sistrurus T. Tergeminus, In Texas, Mitchell R. Barazowski

Biology Theses

Habitat suitability modeling using the software package MaxEnt (Phillips, Anderson, & Schapire, 2006) is a popular method for describing the habitat of rare species. MaxEnt uses “presence only” data to develop models; however presence data are highly skewed towards areas of high detection probability and these areas may not represent the full range of habitat use. Thusly, predictions from models developed using only data from areas with high detection probability may not represent all suitable habitat. This study tested the ability of MaxEnt models developed using three different data sets to accurately describe Western Massasauga (Sistrurus t. tergeminus) habitat at …

Review Of Northwestern African Buthacus, With Description Of Buthacus Stockmanni Sp. N. From Morocco And Western Sahara (Scorpiones, Buthidae), František Kovařík, Graeme Lowe, František Šťáhlavský

Euscorpius

Northwestern African Buthacus species are revised. Buthacus stockmanni sp. n. from Morocco and Western Sahara is described and fully complemented with color photos of live and preserved specimens, as well as their habitat. The hemispermatophore of B. stockmanni sp. n. is illustrated and described. In addition to morphology and hemi-spermatophores, we also describe the karyotypes of B. stockmanni sp. n. (2n=20). B. stockmanni sp. n. is compared with B. occidentalis Vachon, 1953 and B. ziegleri Lourenço, 2000. Both these species are differentiated from B. stockmanni sp. n. geographically and morphologically. The male of B. stockmanni sp. n. has fingers of …

First Report Of Lissothus Occidentalis Vachon, 1950 (Scorpiones: Buthidae) From Morocco And Western Sahara, With Notes On Ecology And Captive Breeding, Mark Stockmann, Carlos Turiel, Felix Althoff, Graeme Lowe, František Kovařík

Euscorpius

Genus Lissothus Vachon, 1948 represented by L. occidentalis Vachon, 1950 is reported for the first time from four localities in Morocco and the Western Sahara. We provide a revised diagnosis of L. occidentalis, fully complemented with color photos of live and preserved specimens. Hemispermatophore is also illustrated and described in detail. Furthermore, we describe aspects of the ecology of this species, and provide photos of collection sites and habitats. We also report on the reproductive biology of this species based on captive breeding and rearing. and provide the first envenomation report for the species.

Animals Aren’T Persons, But Is It Time For A Neologism?, Helen Steward

Animal Sentience

Mark Rowlands argues that at least some animals are persons, based on the idea that (i) many animals have a property he calls “pre-reflective awareness,” (ii) the capacity for pre-reflective awareness is sufficient to satisfy the traditional Lockean definition of personhood, and (iii) satisfaction of the traditional Lockean definition of personhood is sufficient for being a person. I agree with (i) and can see that there is a persuasive case for (ii), but I think the case against (iii) blocks the conclusion that animals are persons. I suggest that we may need instead to coin a neologism in order to …

Reber’S Caterpillar Offers No Help, Carl Safina

Animal Sentience

Reber’s target article “Caterpillars, consciousness and the origins of mind” seems only to shift but not to address the question of where the mind is and how minds occur.

Report Of A Meeting On Contemporary Topics In Zebrafish Husbandry And Care, Nikki Osborne, Gregory Paull, Adam Grierson, Karen Dunford, Elisabeth M. Busch-Nentwich, Lynne U. Sneddon, Natalie Wren, Joe Higgins, Penny Hawkins

Fall Field Report, August–November 2016, W. Ross Silcock

Nebraska Bird Review

As usual, there was quite a bit to chew over in the Fall Seasonal Report, although it was generally a pretty uneventful season, especially among waterfowl and shorebirds. The mild fall allowed some good counts to occur, such as the 20+ Surf Scoters, 465 meadowlarks in Garfield Co, and at least 11 White-winged Doves.

First State Records are hard to come by; amazing was an Anna's Hummingbird that showed up in the Manning Family's central Omaha yard. How many pass through the yards of non-birders undetected? Always a mind-boggling thought. A 3rd state record Costa's Hummingbird came to light from …

Survey Of Nasal Mites (Acari: Rhinonyssidae, Ereynetidae, Turbinoptidae) In Birds From Three States In The United States, Alexis Danel Hilario Perez

Graduate Theses and Dissertations

Avian nasal mites are obligate endoparasites that spend their entire life in the respiratory system of birds. In North America, bird nasal mites are represented by different unrelated families in three different orders of mites: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), and the Cytoditidae and Turbinoptidae (Astigmata). The most-diverse and most-abundant family of nasal mites is the Rhinonyssidae, in which mite species may have different levels of host specificity from host orders to families or even species level. Nasal mites in North America have been surveyed in different locations, such as studies ranging from the Gulf Coast of the US to Canada. …

Wolf Predation: Where And How Wolves Kill Beavers, And Confronting The Biases In Scat-Based Diet Studies, Thomas Gable

All NMU Master's Theses

Beavers can be a significant prey item for wolves in boreal systems but how wolves hunt beavers is largely unknown. I inferred how wolves hunt beavers by identifying 22 kill sites using clusters of locations from GPS-collared wolves in Voyageurs National Park, Minnesota. Where wolves killed beavers varied seasonally with the majority (58%) of kills in the spring occurring below dams and on shorelines while the majority (80%) of kills in the fall were near feeding trails and canals. I deduced that the typical hunting strategy has 3 components: 1) waiting near areas of high beaver use until a beaver …

Relationship Among Genetic And Physiological Biomarkers, And Horse Characteristics, Casey Orr

Graduate Theses and Dissertations

The objective of this study was to evaluate relationships among genetic and physiological biomarkers and phenotypic characteristics in horses. Three breeds (Quarter Horse, Thoroughbreds, Miniatures), and five genes of interest (leptin, ghrelin, cytochrome P450, glucocorticoid receptor, and lactate dehydrogenase) were the basis of the investigation. Genomic DNA was extracted from buffy coat samples of Quarter Horses (n = 21), Thoroughbreds (n = 26), and Miniatures (n = 34). Data were analyzed using MIXED MODEL procedures of SAS, with the main effects of breed and SNP genotype. Horse was the experimental unit, and dependent variables were classified as physical, cell differentials, …

Using Storytelling To Raise Interest In Vultures, Elise C. Osenga

The Transdisciplinary STEAM+ Journal

The tradition of oral storytelling is an art that stretches back to humankind's earliest cultures. While storytelling is often considered as a form of entertainment, it has also long been used as a teaching tool as well-- a way of engaging listeners to come to new understanding of their world through subtle means. It is my belief that stories, particularly stories with a clear tie to students' sense of place, can be more widely applied to effectively generate interest in specific scientific topics and help students to form emotional connections with the topics under discussion. The following personal narrative describes …

Two New Species Of Euscorpius Thorell, 1876 From Southern Turkey (Scorpiones: Euscorpiidae), Gioele Tropea, Ersen Aydın Yağmur

Euscorpius

Two new species of scorpion of the genus Euscorpius Thorell, 1876 are described from southern Turkey based on morphological ratio and trichobothrial data. E. hakani sp. n. from Mt. Eşeler, in Denizli Province in southwestern Turkey and E. aladaglarensis sp. n. from the Aladağlar Mts., in Niğde, Kayseri, and Adana Provinces. With the description of two new taxa, 17 species of Euscorpius are currently recognized in Turkey.

Insect Consciousness: Commitments, Conflicts And Consequences, Colin Klein, Andrew B. Barron

Animal Sentience

Our target article, “Insects have the capacity for subjective experience,” has provoked a diverse range of commentaries. In this response we have collated what we see as the major themes of the discussion. It is clear that we differ from some commentators in our commitments to what subjective experience is and what the midbrain is capable of. Here we clarify where we stand on those points and how our view differs from some other influential perspectives. The commentaries have highlighted the most lively areas of disagreement. We revisit here the debates surrounding whether the cortex is essential for any form …

Consciousness And Evolutionary Biology, Yew-Kwang Ng

Animal Sentience

Reber’s axiom: “Any organism with flexible cell walls, a sensitivity to its surrounds and the capacity for locomotion will possess the biological foundations of mind and consciousness” does not seem to be supported by things we know and the logic of evolutionary biology. The latter leads to the conclusion that conscious species are flexible in their behavior (rather than in their cell walls), as argued in Ng (1995, 2016). Locomotion may be completely hard-wired and need not involve consciousness. It is hard enough to explain how consciousness could emerge in a sophisticated brain: Isn’t it a harder problem to show …

Body Mass Estimates From Bone And Tooth Measurements In White-Tailed Deer, Odocoileus Virginianus, Brandi Morris, Alfred J. Mead

Georgia Journal of Science

The distal forelimbs and mandibles of 110 female and 240 male white-tailed deer (Odocoileus virginianus) from the Piedmont National Wildlife Refuge, Georgia, were used to examine the relationship between metacarpal dimensions, first lower molar occlusal surface area, and mandibular width versus body mass. The strongest correlation was found between female metacarpal proximal area vs. body mass (R2 = 0.74). The combined-sexes metacarpal proximal area vs. body mass displayed a lower correlation (R2 = 0.54). The female first lower molar surface area vs. body mass produced the highest dental correlation (R2 = 0.56). The study suggests that body mass estimates using …

The Difference Between Conscious And Unconscious Brain Circuits, Ezequiel Morsella, Zaviera Reyes

Animal Sentience

Theoretical frameworks in which consciousness is an inherent property of the neuron must account for the contrast between conscious and unconscious processes in the brain and address how neural events can ever be unconscious if consciousness is a property of all neurons. Other approaches have sought answers regarding consciousness by contrasting conscious and unconscious processes and through investigating the complex interactions between the two kinds of processes, as occurs most notably in human voluntary action. In voluntary action, consciousness is associated most, not with motor control or low-level perceptual processing, but with the stage of processing known as action selection.

Resolving The Hard Problem And Calling For A Small Miracle, Arthur S. Reber

Animal Sentience

With the exception of the commentary by Key, the commentaries on Reber have a common feature: the commenters feel, with varying levels of enthusiasm, that there is at least some virtue in the core assumption of the Cellular Basis of Consciousness (CBC) theory that consciousness (or subjectivity or sentience) accompanies the earliest forms of life. The model has two important entailments: (a) it resolves the (in)famous Hard Problem by redirecting the search for the biochemical foundations of sentience away from human consciousness; and (b) it reduces the need for an emergentist miracle to a far simpler scale than is currently …

No Help On The Hard Problem, Derek Ball

Animal Sentience

The hard problem of consciousness is to explain why certain physical states are conscious: why do they feel the way they do, rather than some other way or no way at all? Arthur Reber (2016) claims to solve the hard problem. But he does not: even if we grant that amoebae are conscious, we can ask why such organisms feel the way they do, and Reber’s theory provides no answer. Still, Reber’s theory may be methodologically useful: we do not yet have a satisfactory theory of consciousness, but perhaps the study of simple minds is a way to go about …

Unconscious Higher-Order Thoughts (Hots) As Pre-Reflective Self-Awareness?, Rocco J. Gennaro

Animal Sentience

Rowlands argues that many nonhuman animals are “persons,” contrary to the prevailing orthodoxy which rests on a mistaken conception of the kind of self-awareness relevant to personhood. He argues that self-awareness bifurcates into two importantly different forms — reflective self-awareness and pre-reflective self-awareness — and that many animals can have the latter, which is sufficient for personhood. I agree that there is good reason to think that many animals can have pre-reflective self-awareness, but I think Rowlands is mistaken about its nature. His account runs the risk of leading to an infinite regress objection, and his notion of pre-reflective self-awareness …

The Psychological Concept Of “Person”, Kristin Andrews

Animal Sentience

Reluctance to overextend personhood seems to drive many of the skeptical responses in the first round of commentaries on Rowlands's target article. Despite Rowlands’s straightforward Response that we already accept some nonhumans as persons, there is still hesitation to accept that other nonhuman animals are persons. Rowlands's argument is sound but the skeptics don’t accept the Lockean notion of person. The metaphysical sense of person is a psychological one, however, and psychological properties grant one moral status according to many ethical theories.

Acoustic Evidence Of Bats Using Rock Crevices In Winter: A Call For More Research On Winter Roosts In North America, Cliff A. Lemen, Patricia W. Freeman, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Northern Long-eared Myotis (Myotis septentrionalis) is known to hibernate in mines and caves, often using cracks within these hibernacula as roost sites. We hypothesized that M. septentrionalis might use deep cracks in rock outcrops for hibernation as well. To test this hypothesis, we placed acoustical bat detectors near rock outcrops away from any known mines or caves during winter in Nebraska. We documented calls of M. septentrionalis as well as Perimyotis subflavus and Eptesicus fuscus in December near rock outcrops, which suggests that individuals of all three species were hibernating in rock crevices in winter. Of the …

Review: Interspecies Ethics By Cynthia Willett, Thomas E. Randall

Between the Species

This paper provides a review of Cynthia Willett's book Interspecies Ethics. Willett aims to outline the beginnings of biosocial eros ethics – an ethical outline that sketches the potentiality of a cross-species cosmopolitan ideal of compassion (agape), derived through acknowledging and emphasizing the existence of spontaneous, playful interaction between social animals. Though this book is recommended for offering an innovative framework from which to explore the possibility of non-anthropocentric cross-species ethic, readers should be wary of expecting to find a fully-fledged moral program detailing how this would work.
