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

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

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.

A Species-Level Phylogeny Of Extant Snakes With Description Of A New Colubrid Subfamily And Genus, Alex Figueroa, Alexander D. Mckelvy, L. Lee Grismer, Charles D. Bell, Simon P. Lailvaux

Publications and Research

Background With over 3,500 species encompassing a diverse range of morphologies and ecologies, snakes make up 36% of squamate diversity. Despite several attempts at estimating higherlevel snake relationships and numerous assessments of generic- or species-level phylogenies, a large-scale species-level phylogeny solely focusing on snakes has not been completed. Here, we provide the largest-yet estimate of the snake tree of life using maximum likelihood on a supermatrix of 1745 taxa (1652 snake species + 7 outgroup taxa) and 9,523 base pairs from 10 loci (5 nuclear, 5 mitochondrial), including previously unsequenced genera (2) and species (61).

Results Increased taxon sampling resulted …

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

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 …

Are Cattle Surrogate Wildlife? Savanna Plant Community Composition Explained By Total Herbivory More Than Herbivore Type, Kari E. Veblen, Lauren M. Porensky, Corinna Riginos, Truman P. Young

Wildland Resources Faculty Publications

The widespread replacement of wild ungulate herbivores by domestic livestock in African savannas is composed of two interrelated phenomena: (1) loss or reduction in numbers of individual wildlife species or guilds and (2) addition of livestock to the system. Each can have important implications for plant community dynamics. Yet very few studies have experimentally addressed the individual, combined, and potentially interactive effects of wild vs. domestic herbivore species on herbaceous plant communities within a single system. Additionally, there is little information about whether, and in which contexts, livestock might functionally replace native herbivore wildlife or, alternatively, have fundamentally different effects …

Dogs & Society: Anglo-American Sociological Perspectives (1865-1934), Michael R. Hill, Mary Jo Deegan

Zea E-Books Collection

HUMANS AND DOGS have a long, wonderful and sometimes problematic association. At a personal level, dogs have been integral to our lives, and our parents’ lives, for as long as the two of us can remember. As sociologists, we also recognize that dogs are important at the macro level. Here, we introduce a selection of early sociological arguments about dogs and their social relationships with humankind. Our interest in developing this book began when we encountered the delightful essays on dogs by Charlotte Perkins Gilman and Annie Marion MacLean — two insightful Anglo-American sociologists who present opposing sympathies regarding the …

Review Of Potential Fisheries And Marine Management Impacts On The South-Western Australian White Shark Population, S M. Taylor, J M. Braccini, R Mcauley, Wayne J. Fletcher

Fisheries Research Reports

Following five fatal incidents involving white sharks (Carcharodon carcharias) off the lower west coast of Western Australia between September 2011 and July 2012, as well as other highly-publicised non-fatal encounters with this species, in 2012 the State Government funded several new initiatives to better understand white sharks in Western Australia and the likely effectiveness of any community safety interventions in Western Australian waters.

The Effects Of Drought On Diets Of Apex Predators In The South African Lowveld Inferred By Fecal Hair Analysis, Shelby Wade

Mahurin Honors College Capstone Experience/Thesis Projects

To properly manage offtake quotas and conservation efforts, Balule Nature Reserve (South Africa) instituted a study in 2014 to determine prey species selection by megapredators. In 2015, Balule Nature Reserve received about 190 mm less rainfall between the months of January and June than in 2014 (116 mm less than average). This study compares the diets of lions and hyaenas between 2014 and 2015. Prey species consumed were determined by fecal analysis, and results were compared to prey availability. Sixteen, 1 km2 plots were chosen from the 400 km2 Reserve. Between June and August 2015, we walked three, 1 km …

A Pilot Study Of Sheep Disease Surveillance In Western Australia, Roy Butler

Conference papers and presentations

A pilot study of sheep disease surveillance was conducted in 2014-2015 on four farms in the eastern wheatbelt of Western Australia. The participants observed their sheep, sufficiently closely to notice disease, at least every second day. Most of the disease syndrome reports related to fewer than five sheep, demonstrating that farmers noticed problems in individual sheep, and not only in groups of sheep. Of a total of 66 disease syndrome observations reported over 12 months, the three most frequently occurring syndromes were found dead + sudden death (combined), skin lesions, and lameness.

Genetic Diversity Among Eight Dendrolimus Species In Eurasia (Lepidoptera: Lasiocampidae) Inferred From Mitochondrial Coi And Coii, And Nuclear Its2 Markers, Alexander Kononov, Kirill Ustyantsev, Baode Wang, Victor C. Mastro, Victor Fet, Alexander Blinov, Yuri Baranchikov

Biological Sciences Faculty Research

Background: Moths of genus Dendrolimus (Lepidoptera: Lasiocampidae) are among the major pests of coniferous forests worldwide. Taxonomy and nomenclature of this genus are not entirely established, and there are many species with a controversial taxonomic position. We present a comparative evolutionary analysis of the most economically important Dendrolimus species in Eurasia.

Results: Our analysis was based on the nucleotide sequences of COI and COII mitochondrial genes and ITS2 spacer of nuclear ribosomal genes. All known sequences were extracted from GenBank. Additional 112 new sequences were identified for 28 specimens of D. sibiricus, D. pini, and D. superans from five …

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 …

Consequences Of Hatch Phenology On Stages Of Fish Recruitment, David M. Bogner, Mark A. Kaemingk, Melissa R. Wuellner

Natural Resource Management Faculty Publications

Little is known about how hatch phenology (e.g., the start, peak, and duration of hatching) could influence subsequent recruitment of freshwater fishes into a population. We used two commonly sympatric fish species that exhibit different hatching phenologies to examine recruitment across multiple life stages. Nine yellow perch (Perca flavescens) and bluegill (Lepomis macrochirus) annual cohorts were sampled from 2004 through 2013 across larval, age-0, age-1, and age-2 life stages in a Nebraska (U.S.A.) Sandhill lake. Yellow perch hatched earlier in the season and displayed a more truncated hatch duration compared to bluegill. The timing of hatch influenced recruitment dynamics for …

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 …

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 …

Characterization, Development And Multiplexing Of Microsatellite Markers In Three Commercially Exploited Reef Fish And Their Application For Stock Identification, Laura Taillebois, Christine Dudgeon, Safia Maher, David Crook, Thor Saunders, Diane P. Barton, Jonathan A. Taylor, David J. Welch, Stephen J. Newman, Michael J. Travers, Richard J. Saunders, Jennifer Ovenden

Fisheries Research Articles

Thirty-four microsatellite loci were isolated from three reef fish species; golden snapper Lutjanus johnii, blackspotted croaker Protonibea diacanthus and grass emperor Lethrinus laticaudis using a next generation sequencing approach. Both IonTorrent single reads and Illumina MiSeq paired-end reads were used, with the latter demonstrating a higher quality of reads than the IonTorrent. From the 1–1.5 million raw reads per species, we successfully obtained 10–13 polymorphic loci for each species, which satisfied stringent design criteria. We developed multiplex panels for the amplification of the golden snapper and the blackspotted croaker loci, as well as post-amplification pooling panels for the grass …

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 …

A Landscape Approach To Determining And Predicting Juvenile Coho Salmon (Oncorhynchus Kisutch) Movement Timing And Growth Patterns Prior To Ocean Entry, Amelia Lee Johnson

Dissertations and Theses

Coho salmon (Oncorhynchus kisutch) rely on unique habitats during the winter season, which may dictate how much individuals may grow and when migration from freshwater rearing habitat to the ocean occurs. Here I analyze movement timing and growth patterns for coho salmon through a field-based study and a literature review. For the field portion, I examined hatchery-stocked juvenile coho salmon across four stream basins in the Russian River watershed, California to determine the relative importance of climate, landscape, and fish size metrics in predicting movement and growth patterns over a winter rearing and spring smolt outmigration time period …

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

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.

Fisheries Research Articles

Creating large conservation zones in remote areas, with less intense stakeholder overlap and limited environmental information, requires periodic review to ensure zonation mitigates primary threats and fill gaps in representation, while achieving conservation targets. Follow-up reviews can utilise improved methods and data, potentially identifying new planning options yielding a desirable balance between stakeholder interests. This research explored a marine zoning system in north-west Australia–a biodiverse area with poorly documented biota. Although remote, it is economically significant (i.e. petroleum extraction and fishing). Stakeholder engagement was used to source the best available biodiversity and socio-economic data and advanced spatial analyses produced 765 …

Expert Elicitation On The Uncertainties Associated With Chronic Wasting Disease, Michael G. Tyshenko, Tamer Oraby, Shalu Darshan, Margit Westphal, Maxine C. Croteau, Willy Aspinall, Susie Elsaadany, Daniel Krewski, Neil Cashman

School of Mathematical & Statistical Sciences Faculty Publications

A high degree of uncertainty exists for chronic wasting disease (CWD) transmission factors in farmed and wild cervids. Evaluating the factors is important as it helps to inform future risk management strategies. Expert opinion is often used to assist decision making in a number of health, science, and technology domains where data may be sparse or missing. Using the "Classical Model" of elicitation, a group of experts was asked to estimate the most likely values for several risk factors affecting CWD transmission. The formalized expert elicitation helped structure the issues and hence provide a rational basis for estimating some transmission …
