Effects Of Early‑Life Experience On Innovation And Problem‑Solving In Captive Coyotes, Andrew C. Garcia, Mitchell A. Parsons, Julie K. Young Sep 2022

Effects Of Early‑Life Experience On Innovation And Problem‑Solving In Captive Coyotes, Andrew C. Garcia, Mitchell A. Parsons, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Early-life experience often shapes behaviors like innovation and exploration. These behaviors are important to animals encountering novel food resources in diverse habitats, such as mesocarnivores in urban areas. To understand if early-life experiences impact later-life behavior, we examined how coyotes (Canis latrans) responded to a multi-access puzzle box at two life stages: pup (~ 7 weeks) and dispersal (~ 10 months). We first exposed pups, still living with their parents and littermates, to a baited puzzle box. At dispersal age, we again tested both these pups and an age-matched control group that was not exposed to the puzzle …


Mapping Natural Genetic Variants Associated With Nutrient Response, Kenneth Wilson Sep 2022

Mapping Natural Genetic Variants Associated With Nutrient Response, Kenneth Wilson

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Phenotypic responses to dietary intake affect every individual, yet individuals consuming similar diets frequently display a myriad of different responses. As diet-related disorders are abundant in humans, understanding the means by which an individual’s genetics dictate these physiological responses is essential. Furthermore, dietary restriction has been shown to dramatically increase the length of lifespan in Drosophila melanogaster, but the exact genetic mechanisms governing this response are still not fully understood. In this study, I have used the Drosophila melanogaster Genetic Reference Panel (DGRP) to pinpoint specific quantitative trait loci associated with a number of diet-induced complex traits so as to …

Imposing Liabilities On Persons Of Influence: An Urgent Step Towards Public Policy Measures In India, Trupti Panigrah Sep 2022

Imposing Liabilities On Persons Of Influence: An Urgent Step Towards Public Policy Measures In India, Trupti Panigrah

International Journal on Consumer Law and Practice

The persons of influence in India have always enjoyed extravagant love and demonstration thereof from the Indian Fan Community. It is not wrong to call this community as one of worshippers or devotees for they have elevated such persons to the position of Gods. This position has enabled persons of influence, whether film-stars or religious gurus, to exercise their influence on their devotees in an almost-absolute manner. While the Indian legal scenario has recognised and enforced the rights of these persons of influence in their personalities, it was not until recently that a legal duty was imposed on them for …

A Decision-Support System For Economic Feasibility Of Subsurfaced Poultry Litter, Tim J. Stults, Michael P. Popp Sep 2022

A Decision-Support System For Economic Feasibility Of Subsurfaced Poultry Litter, Tim J. Stults, Michael P. Popp

Journal of Applied Farm Economics

Cattle (Bos spp.) producers routinely spread fertilizer or broadcast poultry (Gallus gallus L.) litter to improve forage production. With poultry litter widely available across the southeastern United States and being a cheaper source of plant nutrition than commercial fertilizer when proximal to application sites, the novel application of litter below the soil surface, while costly, allows for greater nutrient retention than broadcasting. Since quantifying costs and benefits of subsurfaced litter is complex, we develop and present a decision support spreadsheet for automated farm-scale model comparisons across modes of nutrient management. We compare subsurfaced litter to commercial fertilizer and broadcast litter …

Perennial Warm-Season Grass Forages Impact On Cow-Calf Profitability In The Fescue Belt, Kyle A. Brazil, Patrick D. Keyser, Andrew P. Griffith, Christopher N. Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

Incorporating a perennial warm- season grass (WSG) into tall fescue (Lolium arundina-ceum [Schreb.] Darbysh.) forage systems in the fescue belt can help avoid the effects of fescue toxicosis on beef cattle (Bos taurus) reproduction and animal performance and provide forage during summer when fescue production is low. However, little information is available on the economics of incorporating WSG into fescue-based forage systems. We developed a simulation model to compare profitability of three forage systems—100% tall fescue, 70% tall fescue/30% bermudagrass (Cynodon dactylon), and 70% tall fescue/ 30% switchgrass (Panicum virgatum)—while also comparing spring- …
