Animal Suffering And Human Bias, Stijn Bruers

Animal Sentience

Ng proposes concrete ways to decrease animal suffering on the basis of commonsense economic logic and research in welfare biology. But to reduce animal suffering effectively in livestock farming, animal experimentation or the natural environment we have to become more aware of our pervasive and spontaneous but unreliable intuitive moral judgments. These can generate biases that prevent us from decreasing animal suffering effectively.

Short Communication: Effect Of Storage Temperature On The Solubility Of Milk Protein Concentrate 80 (Mpc80) Treated With Nacl Or Kcl, V. Sikand, P.S. Tong, J. Walker, T. Wang, L.E. Rodriguez-Saona

Dairy Science

A previous study in our laboratory showed that addition of 150 mM NaCl or KCl into diafiltration water improved the solubility of freshly made milk protein concentrate 80 (MPC80). In the present study, the objectives were (1) to evaluate the solubility of NaCl- or KCl-treated MPC80 samples kept at varying temperatures and then stored for extensive periods at room temperature (21°C ± 1°C); and (2) to determine if MPC80 samples stored at different temperatures and protein conformation can be grouped or categorized together. Freshly manufactured MPC80 samples were untreated (control), processed with NaCl, or processed with KCl. One set …

Circulating Amino Acids In Blood Plasma During The Peripartal Period In Dairy Cows With Different Liver Functionality Index, Z. Zhou, J. J. Loor, F. Piccioli-Cappelli, F. Librandi, G. E. Lobley, E. Trevisi

Physiology Collection

The liver functionality index (LFI) measures the changes of albumin, cholesterol, and bilirubin concentrations between 3 and 28 d postpartum. This composite index, based on variables with direct relevance to liver-specific plasma protein synthesis (albumin), hepatic/intestinal lipoprotein synthesis (cholesterol), and clearance of breakdown products of heme catabolism (bilirubin), provides a tool for evaluating manifestations of hepatic disease. Both energy and protein metabolism are likely to be affected by various physiological challenges in this period but have not been tested systematically. The present study was conducted to profile AA in cows with high or low LFI during the peripartal period …

From Clinging To Digging: The Postembryonic Skeletal Ontogeny Of The Indian Purple Frog, Nasikabatrachus Sahyadrensis (Anura: Nasikabatrachidae), Gayani Senevirathne, Ashish Thomas, Ryan R. Kerney, James Hanken, S. D. Biju, Madhava Meegaskumbura

Biology Faculty Publications

The Indian Purple frog, Nasikabatrachus sahyadrensis, occupies a basal phylogenetic position among neobatrachian anurans and has a very unusual life history. Tadpoles have a large ventral oral sucker, which they use to cling to rocks in torrents, whereas metamorphs possess adaptations for life underground. The developmental changes that underlie these shifts in habits and habitats, and especially the internal remodeling of the cranial and postcranial skeleton, are unknown. Using a nearly complete metamorphic series from free-living larva to metamorph, we describe the postembryonic skeletal ontogeny of this ancient and unique monotypic lineage. The torrent-dwelling larva possesses a dorsoventrally flattened …

Unearthing The Fossorial Tadpoles Of The Indian Dancing Frog Family Micrixalidae, Gayani Senevirathne, Sonali Garg, Ryan R. Kerney, Madhava Meegaskumbura, S. D. Biju

Biology Faculty Publications

Tadpoles of the monotypic Indian dancing frog family Micrixalidae have remained obscure for over 125 years. Here we report the discovery of the elusive tadpoles of Micrixalus herrei from the sand beds of a forested stream in southern Western Ghats, and confirm their identity through DNA barcoding. These actively burrowing tadpoles lead an entirely fossorial life from eggs to late metamorphic stages. We describe their internal and external morphological characters while highlighting the following features: eel-like appearance, extensively muscularized body and tail, reduced tail fins, skin-covered eyes, delayed development of eye pigmentation in early pre-metamorphic stages (Gosner stages 25–29), prominent …

Challenges And Opportunities In The Culture Of Giant Freshwater Prawn In The Philippines, Janice A. Ragaza

Biology Faculty Publications

Amid the irremediable decline of capture fisheries, the Philippine government has identified aquaculture as a sector that will ensure food security and generate new job opportunities geared toward the country’s goal of economic development (Nagothu and Ortiz 2007). Aquaculture of giant freshwater prawn Macrobrachium rosenbergii (Fig. 1) is an emerging program that is intended to expand and vary the aquatic species used in freshwater aquaculture, which is still predominantly based on tilapia (Rosario and Tayamen 2004). Attractive characteristics of freshwater prawn culture include ease of breeding, high hatching rate, superior quality of meat and high market value (Keysami and Mohammadpour …

Winter Field Report, December 2015 To February 2016, W. Ross Silcock

Nebraska Bird Review

As has been the trend in recent years, many species are lingering later in fall and even arriving earlier in spring. Along with lingering birds, mid-winter and overwintering records have increased. This winter was phenomenal in this respect, especially in that records were across the board in terms of species, suggesting that water conditions have moderated (more open water) and temperatures in general have also (passerines). Unprecedented records included first wintering White-winged Scoter and first Jan or Feb record of Orange-crowned Warbler. Second or third such records were set by Blue-winged Teal, Surf Scoter, Ruddy Duck, Eared Grebe, Greater Yellowlegs, …

Improving Cotton Agronomics With Diverse Genomic Technologies, Aaron Robert Sharp

Theses and Dissertations

Agronomic outcomes are the product of a plant's genotype and its environment. Genomic technologies allow farmers and researchers new avenues to explore the genetic component of agriculture. These technologies can also enhance understanding of environmental effects. With a growing world population, a wide variety of tools will be necessary to increase the agronomic productivity. Here I use massively parallel, deep sequencing of RNA (RNA-Seq) to measure changes in cotton gene expression levels in response to a change in the plant's surroundings caused by conservation tillage. Conservation tillage is an environmentally friendly, agricultural practice characterized by little or no inversion of …

Factors Associated With Anaplasma Spp. Seroprevalence Among Dogs In The United States, Christopher S. Mcmahan, Dongmei Wang, Melissa J. Beall, Dwight D. Bowman, Susan E. Little, Patrick O. Pithua, Julia L. Sharp, Roger W. Stich, Michael J. Yabsley, Robert B. Lund

Publications

Background

Dogs in the United States are hosts to a diverse range of ticks and tick-borne pathogens, including A. phagocytophilum, an important emerging canine and human pathogen. Previously, a Companion Animal Parasite Council (CAPC)-sponsored workshop proposed factors purported to be associated with the infection risk for tick-transmitted pathogens in dogs in the United States, including climate conditions, socioeconomic characteristics, local topography, and vector distribution.

Methods

Approximately four million test results from routine veterinary diagnostic tests from 2011–2013, which were collected on a county level across the contiguous United States, are statistically analyzed with the proposed factors via logistic regression …

2015–2016 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fifteen counts were held during the 2015–16 Christmas Bird Count season, which is one more than last season when the Harrison count was canceled. The Grand Island count was held on December 12, two days prior to the start of the officially sanctioned CBC time slot, but its results are included in this discussion.

Ten of the counts were done on or before December 22 under mild conditions with little snow cover and mostly to entirely open water. While the weather became more seasonable toward the end of the period, it was still fairly benign. As a result, most of …

Eight Years Of Bird Banding In Nebraska’S Chadron State Park, Josh Lefever

Nebraska Bird Review

Each autumn since 2008, the Bird Conservancy of the Rockies has sent a trained biologist to capture, band, and collect data on the birds that make use of the Pine Ridge region on their journey south. Eight years of mist-netting at Chadron State Park, in the heart of the Pine Ridge, has given insights into the unique assemblage of birds found there, and how alteration by fire can affect birds' use of the habitat. The Chadron State Park banding station is located on a hillside near the west edge of the park, with an overstory of Ponderosa Pines and a …

An Animal Victim's Best Chance: Veterinary Legal Duty To Report Cruelty In The U.S., Lora Dunn

Animal Sentience

Legislation throughout the U.S. recognizes animal sentience and the importance of veterinary reporting to combat the ongoing suffering of these animal victims: All 50 states have felony penalties available for animal cruelty crimes, and veterinary reporting is permitted or required in the majority of states. The remaining minority of U.S. states should take action to require veterinarians to report animal cruelty and render veterinarians immune for good faith reporting.

Veterinary Medical Associations Need To Educate Veterinarians For Mandatory Reporting Of Suspected Animal Abuse, Melinda V. Merck

When animals are suffering, we have a duty to take action. With appropriate incentive and educational support mandatory veterinary reporting can be a great legal avenue to help ensure their safety and welfare.

Fish Pain's Burden Of Proof, Carl Safina

Animal Sentience

A hypothesis like Key’s, that fish cannot feel pain, should really be stated as a null hypothesis — an assumption that there is no difference in the things being compared. Then evidence — including anecdotal evidence — for and against rejecting the null hypothesis can be examined and weighed. Key (2016a) has proven only that fish lack mammalian brains.

Burden Of Proof Lies With Proposer Of Celestial Teapot Hypothesis, Brian Key

Animal Sentience

Bertrand Russell famously imagined the existence of a celestial teapot to highlight that the burden of proof of a hypothesis lay with its proposer and it was not the responsibility of others to refute it. Those who propose that fish feel pain must bear the burden of proof for their hypothesis. There are several common arguments adopted by those defending the position that fish feel pain. For instance, proponents envisage that pain is so important for human survival that they can’t imagine fish could exist without it. Out of this argument from incredulity emerges the idea that pain must have …

Associations Between Domestic-Dog Morphology And Behaviour Scores In The Dog Mentality Assessment, Holly R. Stone, Paul D. Mcgreevy, Melissa J. Starling, Bjorn Forkman

Morphology Collection

The domestic dog shows a wide range of morphologies, that humans have selected for in the process of creating unique breeds. Recent studies have revealed correlations between changes in morphology and behaviour as reported by owners. For example, as height and weight decrease, many undesirable behaviours (non-social fear, hyperactivity and attention seeking) become more apparent. The current study aimed to explore more of these correlations, but this time used reports from trained observers. Phenotypic measurements were recorded from a range of common dog breeds (n = 45) and included cephalic index (CI: the ratio of skull width to skull length), …

Swans: Their Biology And Natural History, Paul A. Johnsgard

Zea E-Books Collection

The seven species of swans of the world are an easily and universally recognized group of waterfowl, which have historically played important roles in the folklore, myths and legends in many of the world’s cultures. Among the largest of all flying birds, they have also almost universally been used as symbols of royalty, grace and beauty, and largely for these reasons swans have only rarely been considered acceptable as targets for sport hunting. Swans occur on all the continents except Africa, although most species are associated with the temperate and arctic zones of North America and Eurasia. Among birds, swans …

Animal Suffering In China, Peter J. Li

Science And Sensibility, Bernard E. Rollin

Animal Sentience

The sentience and suffering of animals is obvious to common sense, even if science and industry claim to be agnostic. Economic incentives to reduce the suffering of animals are welcome, but it is not clear whether animals can turn to science for help.

Can Colour Vision Re-Evolve? Variation In The X-Linked Opsin Locus Of Cathemeral Azara’S Owl Monkeys (Aotus Azarae Azarae), N. I. Mundy, N. C. Morningstar, Andrea L. Baden, E. Fernandez-Duque, V. M. Davalos, B. J. Bradley

Publications and Research

Background: Do evolutionary specializations lead to evolutionary constraint? This appears plausible, particularly when specialization leads to loss of complex adaptations. In the owl monkey lineage, nocturnality clearly arose from a diurnal ancestor. This behavioural shift was accompanied by morphological changes in the eye and orbit and complete loss of colour vision via missense mutations in the gene encoding the short-wave sensitive visual pigment (SWS opsin). Interestingly, at least one subspecies of owl monkey, Azara’s owl monkey (Aotus azarae azarae), has regained activity in daylight. Given that all primate species that are active in daylight, including primarily diurnal species and species …

When The Client Is Not The Abuser, But One Of The Abused, Tania Signal

Animal Sentience

The question of client confidentiality and reporting animal abuse is complicated when the client is not the abuser, and when the abuse (of both people and animals) may escalate precisely because it has been (or may be) reported.

Laelapine Mite (Acari: Laelapidae) Morphometric Analysis Reflects Taxonomic And Geographic Clusters Of South American Oryzomyines (Rodentia: Sigmodontinae), Donald Gettinger, Robert D. Owen

MANTER: Journal of Parasite Biodiversity

Ongoing efforts to survey and inventory nonvolant small mammals across the Neotropics are beginning to reveal a highly structured and diverse fauna of rodents and marsupials. By increasing the foundation of specimens in museums around the world, it has become possible, for the first time, to evaluate and quantify the similarities and differences among small mammals collected from a broad range of geographic locali­ties, ecoregions, and habitats. Because ectoparasites were sampled in the process of collecting mammalian voucher specimens, we are able to study the laelapine mites (Acari: Laelapidae) associated with well-iden­tified and verifiable host specimens. Here, we evaluate morphometric …

Two New Scorpions Of The Genus Chaneke Francke, Teruel Et Santibáñez-López, 2014 (Scorpiones: Buthidae) From Southern Mexico, František Kovařík, Rolando Teruel, Graeme Lowe

Euscorpius

Herein we describe two new species of the recently discovered buthid scorpion genus Chaneke Francke, Teruel et Santibáñez-López, 2014. Both are from Oaxaca State in southern Mexico: Chaneke hofereki sp. n. based upon adults of both sexes from a single coastal locality, and Chaneke baldazoi sp. n. based upon adult females and juveniles from a mountain site in the Sierra Madre. Additional information is given on their taxonomy, distribution, ecology, and reproductive biology, fully complemented with color photos of live and preserved specimens, and their habitat.

Injury-Induced Neuronal Turnover With Zinc Sulfate Affects Cilitated Olfactory Sensory Neurons More Than Microvillous Olfactory Sensory Neurons In The Adult Zebrafish, James Hentig

Honors Theses

Zinc sulfate is a known olfactory toxicant, although its effects on the olfactory epithelium of zebrafish have not been examined. Previous observations utilizing Triton X-100 found selective retention of some olfactory sensory neurons and loss of others. Based on those findings, we hypothesized that the retention of the ability to sense amino acids, detected by microvillous olfactory sensory neurons, and loss of the ability to perceive bile salts, detected by ciliated olfactory sensory neurons, is a universal response to chemical ablation. Fish were treated with zinc sulfate and survived for 2, 5, 10 and 14 days post treatment and processed …
