Anthropomorphism, Anthropectomy, And The Null Hypothesis, Kristin Andrews, Brian Huss

Experimentation Collection

We examine the claim that the methodology of psychology leads to a bias in animal cognition research against attributing ‘‘anthropomorphic’’ properties to animals (Sober in Thinking with animals: new perspectives on anthropomorphism. Columbia University Press, New York, pp 85–99, 2005; de Waal in Philos Top 27:225–280, 1999). This charge is examined in light of a debate on the role of folk psychology between primatologists who emphasize similarities between humans and other apes, and those who emphasize differences. Weargue that while in practice there is sometimes bias, either in the formulation of the null hypothesis or in the preference of Type-II …

Laterality Influences Cognitive Performance In Rainbowfish Melanotaenia Duboulayi, Anne-Laurence Bibost, Culum Brown

Sentience Collection

Cerebral lateralization has been suggested to convey a selective advantage to individuals by enhancing their cognitive abilities. Few, however, have explicitly compared the cognitive ability of animals with strongly contrasting laterality. Here, we examined the influence of laterality on learning performance in the crimson spotted rainbowfish, Melanotaenia duboulayi, using a classical conditioning paradigm. We also compared the learning ability of wild caught and captive-reared fish to examine the influence of rearing environment on cognitive performance. Laterality was established by observing which eye fish preferred to use while viewing their mirror image. Subjects were then conditioned to associate the appearance of …

Emotional Engagements Predict And Enhance Social Cognition In Young Chimpanzees, Kim A. Bard, Roger Bakeman, Sarah T. Boysen, David A. Leavens

Sentience Collection

Social cognition in infancy is evident in coordinated triadic engagements, that is, infants attending jointly with social partners and objects. Current evolutionary theories of primate social cognition tend to highlight species differences in cognition based on human-unique cooperative motives. We consider a developmental model in which engagement experiences produce differential outcomes. We conducted a 10-year-long study in which two groups of laboratory-raised chimpanzee infants were given quantifiably different engagement experiences. Joint attention, cooperativeness, affect, and different levels of cognition were measured in 5- to 12-month-old chimpanzees, and compared to outcomes derived from a normative human database. We found that joint …

Música De Las Grullas: Una Historia Natural De Las Grullas De América, Paul A, Johnsgard, Enrique H. Weir, Karine Gil-Weir

Zea E-Books Collection

En un sábado mágico de marzo, maneje con un estudiante de postgrado hasta el valle central del Platte, al oeste de Grand Island, tanto para ver la migración primaveral de aves acuáticas como la de las grullas grises. Tal vez fue una suerte que yo no estuviera preparado emocionalmente para ver como innumerables grullas salpicaban el cielo de horizonte a horizonte, o girando grácilmente sus cabezas como si estuvieran atrapados en algún torbellino de ultra cámara lenta, su vibrato produce una cadencia descendente como la música de un coro aviar angelical. Desde los días de mi infancia, cuando, por primera …

Natural Infections Of Tetrathyridia Of Mesocestoides Species In Deer Mice, Peromyscus Maniculatus, From New Mexico, John E. Ubelaker, Nora Abdullah, Aya Mouhaffel, Rashmi Ananadampillair, Caitlyn Emigh, Scott Lyell Gardner

Papers in Parasitology

At Southern Methodist University campus about 6 miles south of Taos, New Mexico, we recovered tetrathyridia of Mesocestoides in five Peromyscus maniculatus in the summers of 2008 (3 of 129, 0.023%), 2009 (0 of 98, 0%), 2010 (1 of 112, 0.008%), 2011 (0 of 88, 0%), and 2012 (1 of 86, 0.011%). Tetrathyridia from the body cavity of one of the five infected mice were injected into the peritoneal cavity of laboratory white mice, Mus musculus. Our later examination of the laboratory mice revealed heavy infections of tetrathyridia continuing to reproduce asexually. Here we provide important new information on …

Systematics Of The Neotropical Genus Leptodactylus Fitzinger, 1826 (Anura: Leptodactylidae): Phylogeny, The Relevance Of Non-Molecular Evidence, And Species Accounts, Rafael O. De Sá, Taran Grant, Arley Camargo, W. R. Heyer, María Laura Ponssa, Edward Stanley

Biology Faculty Publications

A phylogeny of the species-rich clade of the Neotropical frog genus Leptodactylus sensu stricto is presented on the basis of a total evidence analysis of molecular (mitochondrial and nuclear markers) and non-molecular (adult and larval morphological and behavioral characters) sampled from > 80% of the 75 currently recognized species. Our results support the monophyly of Leptodactylus sensu stricto, with Hydrolaetare placed as its sister group. The reciprocal monophyly of Hydrolaetare and Leptodactylus sensu stricto does not require that we consider Hydrolaetare as either a subgenus or synonym of Leptodactylus sensu lato. We recognize Leptodactylus sensu stricto, Hydrolaetare, Adenomera, and Lithodytes …

The Innate Immune Response In Eisenia Fetida To Microbial Challenges, Aaron Schindler

Journal of Undergraduate Research at Minnesota State University, Mankato

The common earthworm, Eisenia fetida, exhibits a rudimentary immune system. The earthworm needs cellular and chemical responses against a constant microbial exposure from its natural environment. Some cellular and chemical responses are found in the coelomic fluid and have been shown to demonstrate anti-microbial characteristics. This project uses microscopy and modified staining techniques to differentiate and categorize the cellular components found in the coelomic fluid. Following a microbial challenge by Klebsiella pneumoniae, an inflammatory response was initiated. Six groups of earthworms were injected with 0.05 ml of 1.0 x 106 cfu /ml K. pneumoniae on day one and tested over …

Search For The Causative Organism Of Waterfowl Deaths At Lake Onalaska, Derek Skillings

Journal of Undergraduate Research at Minnesota State University, Mankato

American coots (Fulica americana) and diving ducks, including lesser scaup (Aythya affinis) and ring-necked ducks (Aythya collaris) have been dying in significant numbers on Lake Onalaska since 2001. Bird mortality is being attributed to parasitic infections from two intestinal trematodes, Cyathocotyle bushiensis and Sphaeridiotrema globulus. The birds begin dying in as little as two weeks of landing at this lake. Rapid mortality is not typically associated with trematode parasitism. Assuming these birds acquired their infections at Lake Onalaska, leads to the conclusion that our current understanding of the disease in this parasite-host system is lacking. Neorickettsiales are a group of …

Effect Of Conditioned Medium On The Recovery Of Dormant Mycobacteria In Culture, Kelly E. Rock

Journal of Undergraduate Research at Minnesota State University, Mankato

Mycobacterium avium subsp. paratuberculosis (Mpt) is the etiologic agent of Johne’s disease, a chronic intestinal disease in cattle that threatens the economic viability of dairy farming. Diagnostic culture is typically unrewarding until several years after infection when clinical signs can be observed. This leads to widespread infection within the herd. Difficulty in culturing Mpt may be a result of oxidative damage due to the increased metabolic rate when dormant organisms are recovered in a nutrient rich medium. In order to improve recovery it is believed that some organisms secrete a growth factor in times of environmental stress which enables them …

Effect Of Increased Water Temperature On Warm Water Fish Feeding Behavior And Habitat Use, Eric Walberg

Journal of Undergraduate Research at Minnesota State University, Mankato

Global warming could cause changes in species behavior and life history. Stream fish may be significantly affected by climate change because individuals are restricted in their movements by water systems and other physical factors, preventing migration to locations more thermally suitable. The effect of warmer waters on stream fish could change behavior and affect the fish species survival and ultimately ecosystem function. During my experiment I observed the effects of increased water temperature on the feeding behavior and habitat use of two native Minnesota fish species, black crappie (Pomoxis nigromaculatus) and black bullhead (Ameiurus melas). An increase of 2oC over …

Anti-Predator Responses Of Fathead Minnows To Alarm Substance Pheromone, Sarah Thomson

Journal of Undergraduate Research at Minnesota State University, Mankato

In some fish, alarm substances are released from skin cells when they are bitten by a predator, signaling nearby fish in potential danger. Such anti-predator defenses have been studied in the fathead minnow (Pimephales promelas), and some have hypothesized that the response to the alarm substance is not instinctual, but rather fish must learn to associate it with a predation cue such as motion. The purpose of this study is to detect an effect of conditioning (associating alarm substance with predation threat) on minnow responses to alarm substance. We tested the prediction that conditioned fish would react more strongly to …

Atrazine Influence On Northern Pike Sperm Motility And Viability In Minnesota, Andy Stevens, Paul Pallardy

Journal of Undergraduate Research at Minnesota State University, Mankato

Concern has been noted by fish hatchery biologists with the Department of Natural Resources that southern Minnesota northern pike Esox lucius populations have exhibited reduced hatching rates, a trend not occurring with northern Minnesota pike populations. The chemical atrazine is a frequently used herbicide in Minnesota and has been found to cause gonadal dysgenesis and reproductive development issues in amphibians and fish. Sperm, length, and age data were collected from northern pike in four Minnesota lakes. Water samples were obtained from two of the lakes to test for atrazine. Test results indicated atrazine concentrations0.10 and r2 < 0.06 for all regressions). Sperm motility reductions in northern pike could be related to declining populations and warrants further research.

The Abundance And Diversity Of Intestinal Trematodes Collected From Blue Winged Teal And Ring-Neck Ducks Inhabiting Lake Winnibigoshish, Minnesota, Omolayo Ogunnowo

Journal of Undergraduate Research at Minnesota State University, Mankato

This study investigated the abundance and diversity of parasites residing in the digestive tracts of blue winged teal and ring-necked ducks collected at Lake Winnibigoshish, MN. The trematode parasites we focused on in this study were removed from the anterior-most, 15cm segment of the small intestine of 10 individuals of each bird species. The parasites were initially stored in 10% formalin and were subsequently stained with Schneider’s aceto carmine, then mounted on microscope slides for diagnostic purposes. A total of 1605 trematodes were recovered from the birds. We found that blue wing teal and ring-necked ducks tended to contain different …

New Insight Into The Effects Of Small Heat Shock Proteins On Callipyge Lamb Meat Tenderness, Traci Cramer, Yuan H Brad Kim, Danyi Ma, Jolena N. Waddell, Moriah Penick

The Summer Undergraduate Research Fellowship (SURF) Symposium

Callipyge lambs are a type of sheep that are genetically known to produce tough meat. High expression of calpastatin, which inhibits proteolytic activity of µ-calpain, has been identified as the main factor behind the toughness of callipyge lamb meat. Another group of proteins called small heat shock proteins (sHSP) has recently been suggested for its possible involvement in tenderness development of meat, where up-regulation of sHSP may be associated with toughness. However, the role of sHSP in meat tenderization of callipyge lambs has never been investigated; therefore, the objective of this study is to determine possible involvement of sHSP in …

Background: Domestic cats enjoy an extensive veterinary medical surveillance which has described nearly 250 genetic diseases analogous to human disorders. Feline infectious agents offer powerful natural models of deadly human diseases, which include feline immunodeficiency virus, feline sarcoma virus and feline leukemia virus. A rich veterinary literature of feline disease pathogenesis and the demonstration of a highly conserved ancestral mammal genome organization make the cat genome annotation a highly informative resource that facilitates multifaceted research endeavors.

Findings: Here we report a preliminary annotation of the whole genome sequence of Cinnamon, a domestic cat living in Columbia (MO, USA), …

Recent Shifts In The Occurrence, Cause, And Magnitude Of Animal Mass Mortality Events, Samuel B. Fey, Adam M. Siepielski, Sébastien Nusslé, Kristina Cervantes-Yoshida, Jason L. Hwan, Eric R. Huber, Maxfield J. Fey, Alessandro Catenazzi, Stephanie M. Carlson

Dartmouth Scholarship

Mass mortality events (MMEs) are rapidly occurring catastrophic demographic events that punctuate background mortality levels. Individual MMEs are staggering in their observed magnitude: re- moving more than 90% of a population, resulting in the death of more than a billion individuals, or producing 700 million tons of dead biomass in a single event. Despite extensive documentation of individual MMEs, we have no understanding of the major features characterizing the occurrence and magnitude of MMEs, their causes, or trends through time. Thus, no framework exists for contextualizing MMEs in the wake of ongoing global and regional perturbations to natural systems. Here …

Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf

STAR Program Research Presentations

Convict cichlids (Archocentrus nigrofasciatus) have developed to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate known predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a female convict cichlid’s aggression toward caring for her offspring when an intruder is introduced. Females attack more in warmer water.

Aquaponics And Basil Plant Density, Danika L. Macmaster, Brook Murphy, Dudley Burton

STAR Program Research Presentations

Aquaponics is the use of water from a fish tank to provide nutrients to plants in a soil-less environment. The rocks cultivate the bacteria that turns the ammonia into nitrates that the plants need, and the plant bed functions as a filter for the fish tank. In this study, with the guidance of Doctor Dudley Burton, Doctor Brook Murphy, we researched the optimal plant density for basil in an Aquaponics system. We attempted to control or measure all the other variables to consider, as to isolate the variable of distance between plants. The water flow was spread through the plant …

Efficacy Of An Electronic Scarecrow On 4 Mammalian Crop-Raiders In Limpopo Province, South Africa, Merrie Renee Richardson

Masters Theses & Specialist Projects

In South Africa, 2 primate species, Chacma baboons (Papio ursinus) and vervet monkeys (Chlorocebus pygerythrus), and 2 nocturnal mammals, Cape porcupine (Hystrix africaeaustralis) and bushbuck (Tragelaphus scriptus), are among many species of crop raiders. Currently, cost-effective, non-lethal solutions are lacking. From June through December 2012, I installed novel electronic scarecrows on two commercial citrus orchards and a private reserve and used video-recording remote cameras to assess cropraiders’ reactions to them in Limpopo Province, South Africa. I used focal animal sampling data from treatment and control group animals to examine differences in activity …

Genome Wide Association Study Of Cholesterol And Poly- And Monounsaturated Fatty Acids, Protein, And Mineral Content Of Beef From Crossbred Cattle, C. M. Ahlberg, Lauren N. Schiermiester, J. T. Howard, Chris R. Calkins, Matthew L. Spangler

Department of Animal Science: Faculty Publications

The objectives were to determine the variation explained by the BovineSNP50v2 BeadChip for cholesterol (CH), polyunsaturated fatty acids (PUFA), monounsaturated fatty acids (MUFA), protein, and minerals in beef cattle, and to identify chromosomal regions that harbor major allelic variants underlying the variation of these traits. Crossbred steers and heifers (n = 236) segregating at the inactive myostatin allele on BTA2 were harvested and steaks were sampled from the M. semitendinosus and the M. longissimus thoracis et lumborum for nutrient analysis. A Bayes C algorithm was employed in genome-wide association analysis. The resulting posterior heritability (SD) estimates ranged from 0.43 (0.10) …

Effects Of Pubertal Status And Number Of Estrous Cycles Prior To Breeding In Beef Heifers, Average Daily Gain On Reproductive Performance And Comparison Of Two Fixed Time Ai Estrus Synchronization Protocols, Rebecca A. Vraspir

Department of Animal Science: Dissertations, Theses, and Student Research

Reproductive success is the most important factor in beef cattle production and is affected by timing of pubertal onset in heifers, and reproductive biotechnologies utilized. Three studies were conducted to evaluate the effects of pubertal status, ADG, and 2 fixed time AI protocols on reproductive success in beef heifers.

In the first study, heifers that were pubertal prior to breeding had a greater AI and overall pregnancy rate; produced more calves born within the first 21 d of the calving season; and weaned older, heavier calves than non-pubertal heifers. Additionally, heifers that had ≥2 estrous cycles, prior to the first …

Energy Content Of Reduced-Fat Dried Distillers’ Grains And Solubles For Lactating Dairy Cows And Effects On Energy And Nitrogen Balance, Alison J. Foth

Department of Animal Science: Dissertations, Theses, and Student Research

Eight Holstein and 8 Jersey multiparous, lactating cows were used to complete 56 energy balances to determine the energy content of reduced-fat distillers grains and solubles (RFDDGS). A repeated switchback design was used to compare treatments with and without RFDDGS. Diets consisted of 24.2 % corn silage, 18.4 % alfalfa hay, 6.94 % brome hay with either 22.9 % rolled corn and 14.8 % soybean meal (Control), or 8.95 % rolled corn, 28.8 % RFDDGS, and 0 % soybean meal (Co-P; DM basis). The inclusion of RFDDGS did not affect (P = 0.86) DMI averaging 21.4 ± 0.53 kg …

Evaluation Of Pre-Harvest Screening For Antibiotics And Flunixin Meglumine In Cattle, Shuna A. Jones

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Many antibiotics and medications used in the treatment of animals have a withdrawal time; residues are a concern for the meat industry. The most recently published 2009 USDA-FSIS Residue Program Data Report listed 135,389 Inspector-in-Charge-Generated (IICG) residue samples from 43,142,500 beef and dairy cattle inspected that year at harvest. Of these samples, 1,306 contained violative antibiotic residues and 327 violative flunixin meglumine residues. Two classes of antimicrobials comprised over half of the documented violative antimicrobial residues (beta-lactams that include ceftiofur and sulfa drugs that include sulfadimethoxine). While the violative residue rate seems small, violative residues are unacceptable. Management of carcasses …

Application Of A Bioenergetics Framework For Assessing Sub-Lethal Effects Of Pollutants In The Freshwater Mussel Elliptio Complanata, Christopher G. Goodchild

All Theses And Dissertations

Although biomarkers are frequently used to assess sublethal effects of contaminants, a lack of mechanistic linkages to higher-level effects limits the predictive power of biomarkers. Bioenergetics has been proposed as a framework for linking cellular effects to whole-animal effects. We investigated sublethal effects of exposure to wastewater treatment facility effluent in freshwater mussels in situ, thereby capturing ecologically relevant exposure conditions. Our study focused on the energetic biomarker AMP-activated protein kinase (AMPK), while also considering more traditional biomarkers like heat shock proteins (HSP70), and antioxidant enzymes (i.e., superoxide dismutase (SOD), glutathione-S-transferase (GST)). We examined biomarkers at mRNA and protein levels. …
