Perceptual Lateralization Of Vocal Stimuli In Goats, Luigi Baciadonna, Christian Nawroth, Elodie F. Briefer, Alan G. Mcelligott

Social Cognition Collection

Functional asymmetries, for example, the preferential involvement of 1 brain hemisphere to process stimuli, may increase brain efficiency and the capacity to carry out tasks simultaneously. We investigated which hemisphere was primarily involved in processing acoustic stimuli in goats using a head-orienting paradigm. Three playbacks using goat vocalizations recorded in different contexts: food anticipation (positive), isolation (negative), food frustration (negative), as well as 1 playback involving dog barks (negative) were presented on the left and right sides of the test subjects simultaneously. The head-orienting response (left or right) and latency to resume feeding were recorded. The direction of the head-orienting ...

Behavioral Flexibility Of A Generalist Carnivore, Sarah E. Daniels, Rachel E. Fanelli, Amy Gilbert, Sarah Sarah Benson‑Amram 2019 University of Wyoming

Behavioral Flexibility Of A Generalist Carnivore, Sarah E. Daniels, Rachel E. Fanelli, Amy Gilbert, Sarah Sarah Benson‑Amram

USDA National Wildlife Research Center - Staff Publications

Innovative problem solving, repeated innovation, learning, and inhibitory control are cognitive abilities commonly regarded as important components of behaviorally flexible species. Animals exhibiting these cognitive abilities may be more likely to adapt to the unique demands of living in novel and rapidly changing environments, such as urbanized landscapes. Raccoons

(Procyon lotor) are an abundant, generalist species frequently found in urban habitats, and are capable of innovative problem solving, which makes them an ideal species to assess their behavioral flexibility. We gave 20 captive raccoons a multi-access puzzle box to investigate which behavioral and cognitive mechanisms enable the generation of innovative ...


A Global Reassessment Of Solitary-Sociable Dolphins, Laetitia Nunny, Mark P. Simmonds 2019 Wild Animal Welfare

A Global Reassessment Of Solitary-Sociable Dolphins, Laetitia Nunny, Mark P. Simmonds

Mark P. Simmonds, OBE

Dolphins are typically regarded as highly social animals. However, some individuals live apart from their own species and may come to socialize with people through a recognized series of stages which are presented and expanded on in this paper. The term “solitary-sociable dolphins” has been used to describe these animals and such individuals have been identified from several different species and reported in many parts of the world. In many instances, the interactions with people that may follow their original isolation, and which typically become more intense over time, have created situations where the welfare of the animal has been ...


People -- Marine Mammal Interactions, Andrew Butterworth, Mark P. Simmonds 2019 University of Bristol

People -- Marine Mammal Interactions, Andrew Butterworth, Mark P. Simmonds

Mark P. Simmonds, OBE

Our relationships with marine mammals are complex. We have used them as resources, and in some places this remains the case; viewed them as competitors and culled them (again ongoing in some localities); been so captivated and intrigued by them that we have taken them into captivity for our entertainment; and developed a lucrative eco-tourism activity focused on them in many nations. When we first envisaged this special topic, we had two overarching aims:

Firstly, we hoped to generate critical evaluation of some of our relationships with these animals.

Secondly, we hoped to attract knowledgeable commentators and experts who might ...

Stable Isotopic Niche Predicts Fitness Of Prey In A Wolf–Deer System, C. T. Darimont, P. C. Paquet, T. E. Reimchen 2019 University of Victoria

Stable Isotopic Niche Predicts Fitness Of Prey In A Wolf–Deer System, C. T. Darimont, P. C. Paquet, T. E. Reimchen

Chris Darimont, Ph.D.

Interindividual variation in niche presents a potentially central object on which natural selection can act. This may have important evolutionary implications because habitat use governs a suite of selective forces encountered by foragers. In a free‐living native black‐tailed deer, Odocoileus hemionus, population from coastal British Columbia, we used stable isotope analysis to identify individual variation in foraging niche and investigated its relationship to fitness. Using an intragenerational comparison of surviving and nonsurviving O. hemionus over 2 years of predation by wolves, Canis lupus, we detected resource‐specific fitness. Individuals with isotopic signatures that suggested they foraged primarily in ...


"My Paintings Would Be No Different Than A Picture In A Biology Textbook", Andi Kur 2019 University of Tennessee at Chattanooga

"My Paintings Would Be No Different Than A Picture In A Biology Textbook", Andi Kur

UReCA: The NCHC Journal of Undergraduate Research & Creative Activity

I find that there are innate balances in life, universal dichotomies that permeate our understanding of the world. My paintings are about a duality such as this that exists between art and science. We are told from youth that these subjects are poles in constant strain, as miscible as oil in water. I spent thirteen years in school believing that I must choose between the two, that it is unnecessary to carry both with me. Drawn between a distinct love of each, I realized how vehemently I disagreed. Everything: every rock to every tree to every person is suspended between ...


Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines 2019 University of Kentucky

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines

Lewis Honors College Capstone Collection

Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim ...

Caracterización De Las Comunidades De Peces Diurnos En Zonas De Pocetas De Los Arroyos De La Hacienda Matepantano (Yopal-Casanare), Juan Sebastian Sanabria Jiménez

Biología

El piedemonte del Casanare forma parte de la cuenca del Orinoco, un ecosistema caracterizado por ser el hábitat del 10% de la biodiversidad del planeta y el 45,8% de las especies ícticas de todo el país, destacándose el río Meta como la zona donde habita el mayor número de especies endémicas. Sin embargo, se ha demostrado que este afluente ha sido pobremente estudiado, requeriendo aumentar la cobertura geográfica de sus inventarios ícticos y caracterizar los aspectos más básicos de la biología de las especies que allí habitan, como lo son los análisis meristicos, el estudio de hábitos alimenticios y ...
