Another New Species Of Euscorpius Thorell, 1876 From The Taurus Mountains In Antalya Province, Southern Turkey (Scorpiones: Euscorpiidae), Gioele Tropea, Ersen Aydın Yağmur, Aristeidis Parmakelis, Kadir Boğaç Kunt Sep 2016

Another New Species Of Euscorpius Thorell, 1876 From The Taurus Mountains In Antalya Province, Southern Turkey (Scorpiones: Euscorpiidae), Gioele Tropea, Ersen Aydın Yağmur, Aristeidis Parmakelis, Kadir Boğaç Kunt

Euscorpius

A new scorpion species, Euscorpius alanyaensis sp. n., is described based on specimens collected from the Taurus Mountains in Antalya Province (Alanya District) in southern Turkey. It is a sibling species of the recently described E. gocmeni Tropea et al., 2014, and similarly, the new species is also characterized by a high trichobothrial count (Pv = 9–11, et = 7, em = 4, and eb = 4), a high pectinal teeth count (Dp = 9–11 in males, 8 in females), medium-small size, and light to medium brown-reddish colour. In addition, for the first time a phylogenetic …


How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans Sep 2016

How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans

Animal Sentience

The sudden appearance of consciousness that Reber posits in creatures with flexible cell walls and motility rather than non-flexible cells walls and no motility involves an evolutionary discontinuity. This kind of “miracle” is required by all “discontinuity” theories of consciousness. To avoid miraculous emergence, one may need to consider continuity theories, which accept that different forms of consciousness and material functioning co-evolve but assume the existence of consciousness to be primal in the way that matter and energy are assumed to be primal in physics.

MANTER: Journal of Parasite Biodiversity

Anthropocommensal rodents live in close proximity to humans in many habitats around the world. They are a threat to public health because of the pathogens they carry. Recent studies in Mérida, Yucatán, México, have shown that commensal rodents harbor potential zoonotic pathogens such as bacteria, helminths, and viruses. In this study, we describe reproductive and demographic parameters of house mice and black rats present in households from Mérida, Yucatán, México, a municipality located in a tropical region in southern México. Rodents were trapped in 142 households within the municipality of Mérida from 2011 to 2014. A total of 832 rodents …


“Cellular Basis Of Consciousness”: Not Just Radical But Wrong, Brian Key Sep 2016

“Cellular Basis Of Consciousness”: Not Just Radical But Wrong, Brian Key

Animal Sentience

Reber (2016) attempts to resuscitate an obscure and outdated hypothesis referred to as the “cellular basis of consciousness” that was originally formulated by the author nearly twenty years ago. This hypothesis proposes that 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. Reber seeks to reduce consciousness to a fundamental property inherent to individual cells rather than to centralised nervous systems. This commentary shows how this hypothesis is based on supposition, false premises and a misunderstanding of evolutionary theory. The cellular basis of consciousness …


The Evolutionary History Of Consciousness, Eirik Søvik, Clint Perry Sep 2016

The Evolutionary History Of Consciousness, Eirik Søvik, Clint Perry

Animal Sentience

Klein & Barron argue that insects are capable of subjective experience, i.e., sentience. Whereas we mostly agree with the conclusion of their arguments, we think there is an even more important message to be learned from their work. The line of reasoning opened by Klein & Barron proves instructive for how neuroscientists can and should explore the biological phenomenon of consciousness.


Beginnings: Physics, Sentience And Luca, Carolyn A. Ristau Sep 2016

Beginnings: Physics, Sentience And Luca, Carolyn A. Ristau

Animal Sentience

According to Reber’s model, Cellular Basis of Consciousness (CBC), sentience had its origins in a unicellular organism and is an inherent property of living, mobile organic forms. He argues by analogy to basic physical forces which he considers to be inherent properties of matter; I suggest that they are instead the stuff of scientific investigation in physics. I find no convincing argument that sentience had to begin in endogenously mobile cells, a criterial attribute of the originator cell(s)for sentience according to CBC. Non-endogenously mobile cells, (i.e., plants or precursors) in a moving environment would suffice. Despite my concerns and the …


Might Insects Experience Pain?, Robert W. Elwood Sep 2016

Might Insects Experience Pain?, Robert W. Elwood

Animal Sentience

The aim of this commentary is to expand the discussion about subjective experience to other arthropods, notably crustaceans. Various species of crustaceans show responses consistent with their feeling pain. Hermit crabs also show prolonged investigation of new shells. They clearly attend to and integrate information from a wide variety of sources that enable them to evaluate the quality of the new shell relative to their current shell. These observations too are consistent with their having subjective experience.


Mind/Body “Hard Problem” Is Not A Category Error, Linda A.W. Brakel Sep 2016

Mind/Body “Hard Problem” Is Not A Category Error, Linda A.W. Brakel

Animal Sentience

Reber’s Cellular Basis of Consciousness (CBC) has much to recommend it. However, while the CBC effectively renders null any ontological gap between mind and body, it leaves two important remaining gaps unaddressed: the epistemologic and the causal gap. Brakel’s (2013) Diachronic Conjunctive Token Physicalism (DiCoToP) is briefly introduced as a beginning remedy for the epistemologic, but unfortunately not the causal, gap. Thus the “hard problem” remains both hard and problematic.


Phenomenal Consciousness In Insects? A Possible Way Forward, Brian Key Sep 2016

Phenomenal Consciousness In Insects? A Possible Way Forward, Brian Key

Animal Sentience

Klein & Barron (2016) propose that subjective experience in humans arises in the midbrain and then argue that insects have the capacity for subjective experience because their nervous system can perform neural processing similar to that of the midbrain. This approach ultimately fails because it is built on the false premise that the midbrain is the source of the awareness of sensory stimuli. I instead propose that the capacity for subjective experience must be based on fundamental neural computations that generate the “what it feels like” experience. Two such computations associated with metarepresentations and high level representations entering working memory …

A Documented Occurrence Of Black Rail (Laterallus Jamaicensis) In Nebraska, Cody Mcgregor, Eric Bruster, Mary Bomberger Brown, Lauren R. Dinan, Joel G. Jorgensen Sep 2016

A Documented Occurrence Of Black Rail (Laterallus Jamaicensis) In Nebraska, Cody Mcgregor, Eric Bruster, Mary Bomberger Brown, Lauren R. Dinan, Joel G. Jorgensen

Nebraska Bird Review

Black Rails (Laterallus jamaicensis) are the smallest of the rails found in North America. Even though they are broadly distributed in coastal tidal and inland freshwater marshes, they are rarely seen and consequently are poorly known. They prefer areas of moist soil interspersed with scattered small pools of shallow water surrounded by fine-stemmed rushes, grasses, and sedges for use during migratory stopover and nesting. All populations of Black Rail have declined precipitously over the past century due to the draining of marshes and wetlands and demands on water resources. In 2011, the U.S. Fish and Wildlife Service initiated …


Summer Field Report, June–July 2016, W. Ross Silcock Sep 2016

Summer Field Report, June–July 2016, W. Ross Silcock

Nebraska Bird Review

This was a routine summer, if there is such a thing. Items of interest involved some rarities, most of which were distributional and temporal, some range changes, and a few issues that triggered more discussion than usual.

The only mega-rarity was Nebraska's second Swallow-tailed Kite; this species has apparently moved northward on the Great Plains in the last couple of years. Distributional rarities included the 3rd record for the east of Long-billed Curlew, a White-eyed Vireo in Cherry Co, the 2nd fall Yellow-throated Vireo record for the Panhandle, the 6th Cherry Co record for Purple Martin, and the 5th and …

Bibliography To Current Knowledge Of Studies Of Pathogens In Colombian Mammals, Viviana Gonzalez-Astudillo, Héctor E. Ramírez-Chaves, Joerg Henning, Thomas R. Gillespie Sep 2016

Bibliography To Current Knowledge Of Studies Of Pathogens In Colombian Mammals, Viviana Gonzalez-Astudillo, Héctor E. Ramírez-Chaves, Joerg Henning, Thomas R. Gillespie

MANTER: Journal of Parasite Biodiversity

Mammals provide an important ecological habitat or niche space to microbial diversity, protistans (or protozoans) and metazoan parasites that can have profound effects on both human and animal health. Thus, understanding the status of mammalian species as hosts for pathogens holds relevance, especially during this time of anthropogenic environmental change. Despite the great diversity in the mammal fauna of Colombia, data in the literature on the occurrence of parasites and pathogens in these mammals are scarce and widely scattered. In order to understand the state of the knowledge of pathogens carried by wild mammals in Colombia, a systematic review of …

The Importance Of Mammalogy, Infectious Disease Research, And Biosafety In The Field, Matthew R. Mauldin, Jeffrey B. Doty, Yoshinori Nakazawa, Ginny L. Emerson, Darin S. Carroll Aug 2016

The Importance Of Mammalogy, Infectious Disease Research, And Biosafety In The Field, Matthew R. Mauldin, Jeffrey B. Doty, Yoshinori Nakazawa, Ginny L. Emerson, Darin S. Carroll

MANTER: Journal of Parasite Biodiversity

Large amounts of data and multitudes of publications have been independently generated by researchers in mammalogy and infectious diseases. The frequent confluence of these fields in epidemiological research as well as the facility of the data generated to be used in applied methods (e.g., conservation, public outreach, public health interventions) suggests that the intersection of these fields is important not only to their committed scientists but also to other areas of investigation, including public health. Given the increased frequency with which researchers in these fields interact with potentially infected humans, animals, and tissues, their occupations present a higher risk of …


If Insects Have Phenomenal Consciousness, Could They Suffer?, Elizabeth S. Paul, Michael T. Mendl Aug 2016

If Insects Have Phenomenal Consciousness, Could They Suffer?, Elizabeth S. Paul, Michael T. Mendl

Animal Sentience

Klein & Barron’s (K & B’s) suggestion that insects have the capacity for phenomenal consciousness is a refreshing and challenging departure from the cautious and agnostic stance that is taken by many researchers when considering this possibility. It is impossible to falsify the sceptic’s view that neural and behavioural parallels between humans and insects need not imply either similar conscious experience or even any phenomenal consciousness in insects at all. But if K & B are right, it is important to consider the possible contents of insect consciousness. Here we discuss whether affective consciousness, with its implications for potential suffering, …


Subjective Experience In Insects: Definitions And Other Difficulties, Shelley Adamo Aug 2016

Subjective Experience In Insects: Definitions And Other Difficulties, Shelley Adamo

Animal Sentience

Whether insects have the potential for subjective experiences depends on the definition of subjective experience. The definition used by Klein & Barron (2016) is an unusually liberal one and could be used to argue that some modern robots have subjective experiences. From an evolutionary perspective, the additional neurons needed to produce subjective experiences will be proportionately more expensive for insects than for mammals because of the small size of the insect brain. This greater cost could weaken selection for such traits. Minimally, it may be premature to assume that small neuronal number is unimportant in determining the capacity for consciousness.


Bacteria And The Cellular Basis Of Consciousness, Michael L. Woodruff Aug 2016

Bacteria And The Cellular Basis Of Consciousness, Michael L. Woodruff

Animal Sentience

According to Reber’s theory, the Cellular Basis of Consciousness (CBC), sentience originates as bio-sensitivity in unicellular organisms. For this reason, Reber regards sentience as evolutionarily foundational. Many bacteria show chemotaxis and, thus, according to CBC, they are sentient. Analysis of the genetic mechanisms underlying bacterial chemotaxis indicates that sentience has no explanatory power in this case. Genetic analysis also fails to show species continuity underlying bio-sensitivity in bacteria and bio-sensitivity in species with nervous systems, so it does not seem that sentience is evolutionary foundational. CBC is rejected on these grounds.


Unity Of Consciousness In Animals, Bernard E. Rollin Aug 2016

Unity Of Consciousness In Animals, Bernard E. Rollin

Animal Sentience

Both Descartes the rationalist and Hume the empiricist, polar opposites philosophically, denied the unity and continuity of animal mind. Kant pointed out that the presence of retrievable memories entails unity of consciousness. Rowlands now argues that animals too have unity of consciousness.

To Bee Or Not To Bee?, Shimon Edelman, Roy Moyal, Tomer Fekete Aug 2016

To Bee Or Not To Bee?, Shimon Edelman, Roy Moyal, Tomer Fekete

Animal Sentience

Klein & Barron’s (2016) (K & B’s) case for insect consciousness is a welcome development in an area that, in all of the science and philosophy of mind, is probably the most anthropocentric. In this commentary, we seek to strengthen K & B’s side of the argument by appealing not just to putative neural mechanisms but also to computational theory that supports it (section 1). We also offer some remarks on three distinctions that are relevant to K & B’s thesis and are central to phenomenal awareness: between the capacity for awareness and its contents (section 2); between …


No Proof For Subjective Experience In Insects, Holk Cruse, Malte Schilling Aug 2016

No Proof For Subjective Experience In Insects, Holk Cruse, Malte Schilling

Animal Sentience

Klein & Barron (2016) provide an inspiring review collecting arguments that show quite related functions in humans and insects. Here we extend the comparison to robots, and formulate two critical objections. One concerns an epistemological question related to the phenomenon of subjective experience. The other questions whether insects need integrated spatiotemporal modeling for navigation.


What Makes Us Conscious Is Not What Makes Us Human, Ezequiel Morsella, Erica B. Walker Aug 2016

What Makes Us Conscious Is Not What Makes Us Human, Ezequiel Morsella, Erica B. Walker

Animal Sentience

Consistent with the promising proposal of Klein & Barron (K & B), we discuss how what makes us conscious appears to be distinct from and more widespread in the animal kingdom than what distinguishes us from other species. Many of the abilities that do distinguish humans from other species (e.g., syntax and co-articulation in speech production) can be mediated unconsciously. The kind of functional architecture proposed by K & B may engender an “action selection bottleneck” in both humans and nonhuman species. As noted by K & B, this bottleneck is intimately related to conscious processing.


Insect Consciousness: Fine-Tuning The Hypothesis, Jon Mallatt, Todd E. Feinberg Aug 2016

Insect Consciousness: Fine-Tuning The Hypothesis, Jon Mallatt, Todd E. Feinberg

Animal Sentience

Although we are mostly supportive, we point out the strengths and weaknesses of Klein & Barron’s (2016) hypothesis that insects have the most basic form of consciousness. The strengths are in their application of Bjorn Merker’s vertebrate-derived ideas to arthropods, using their deep knowledge of insect brains. The weaknesses involve the controversial aspects of some of Merker’s ideas. We describe how the latter can be modified to strengthen the authors’ case for insect consciousness.


Feel Or Perspective?, Mark Rowlands Aug 2016

Feel Or Perspective?, Mark Rowlands

Animal Sentience

The title of Klein & Barron’s well-argued and thought-provoking target article is, “Insects have the capacity for subjective experience.” However, they also frame their claim using the term “consciousness,” which they seem to take as equivalent to “subjective experience.” This assumed equivalence, I shall argue, is problematic in a way that might vitiate their central argument.


Effects Of An Electronic, Motion-Activated Scarecrow On Foraging Time In Nocturnal Vertebrate Crop Pets In South Africa, Mallory Clouse Aug 2016

Effects Of An Electronic, Motion-Activated Scarecrow On Foraging Time In Nocturnal Vertebrate Crop Pets In South Africa, Mallory Clouse

Mahurin Honors College Capstone Experience/Thesis Projects

The normal behaviors of animals can disrupt human activities, resulting in human wildlifeconflict. In South Africa, nocturnal crop raiders are a significant source of human wildlifeconflict for farmers. Major nocturnal pest animals are Cape porcupine (Hystrix africaeaustralis) and bushpig (Potamochoerus larvatus). Although methods of deterring animals from agricultural areas have been explored, nocturnal crop raiding remains difficult to mitigate. Most research studies focus on deterring non-human primates and elephants, but methods that may be successful in deterring such larger mammals are not necessarily effective at discouraging smaller, nocturnal crop raiders. This study examined the efficacy of …
