Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan Oct 2021

Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan

Doctoral Dissertations

Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal …


Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos Sep 2021

Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos

Masters Theses

Primate hair is both a substrate upon which essential social interactions occur and an important host-pathogen interface. As commensal microbes provide important immune functions for their hosts, understanding the microbial diversity in primate hair could provide insight into primate immunity and disease transmission. While studies of human hair and skin microbiomes show differences in microbial communities across body regions, little is known about the nonhuman primate hair microbiome. In this study, we collected hair samples (n=159) from 8 body regions across 12 nonhuman primate species housed at 3 US institutions to examine 1) the diversity and composition of the primate …


New England’S Underutilized Seafood Species: Defining And Exploring Marketplace Potential In A Changing Climate, Amanda Davis Dec 2020

New England’S Underutilized Seafood Species: Defining And Exploring Marketplace Potential In A Changing Climate, Amanda Davis

Masters Theses

New England’s seafood industry has been searching for opportunities to diversify their landings and build resilience as it faces socio-economic challenges from a changing climate. Developing markets for underutilized species is one way the New England community could help their seafood industry build resilience. This thesis identified New England’s underutilized fish species and explored their marketplace potential by examining their availability in a changing climate, current availability to consumers, and consumers’ responses. In Chapter I, I account how New England’s seafood preferences have changed over time. In Chapter II, I identify New England’s seven underutilized seafood species: 1) Acadian redfish …


Wildlife Habitat Management, Paige Warren Jan 2019

Wildlife Habitat Management, Paige Warren

Sustainability Education Resources

The primary goal for this course is to help you put into practice tools you have been acquiring in your other Natural Resources Conservation courses. We will explore wildlife-habitat relationships in depth, through the lenses of basic field zoology and natural history, evolutionary biology, and ecological theory. We will introduce you to quantitative tools used to explain ecological processes and their influence on wildlife and their environment. We will examine the dynamics and management of various habitats in New England, North America, and elsewhere through field visits and use of primary literature. But most importantly, we will ask you to …


River Herring Conservation In Freshwater: Investigating Fish Reproductive Success And The Educational Value Of Citizen Monitoring Programs, Meghna Marjadi Nov 2016

River Herring Conservation In Freshwater: Investigating Fish Reproductive Success And The Educational Value Of Citizen Monitoring Programs, Meghna Marjadi

Masters Theses

Over the last century anadromous alewife (Alosa psuedoharengus) and blueback herring (Alosa aestivalis), collectively called river herring, suffered drastic declines throughout their range from Newfoundland (Canada) to North Carolina (USA). A 2011 petition to include river herring in the Endangered Species Act (ESA) was rejected, partly due to inadequate information towards identifying coast-wide population status. Additionally, knowledge gaps were identified with basic ecology of the river herring life cycle in freshwater, including species reproductive strategies. In Chapter 2, I investigated how body size, spawning arrival time, and sex influence river herring reproductive success. I collaborated with …


From Battery Cages To Barns: A Cost-Benefit Analysis Of A National Standard For Cage-Free Egg Production, Jonathan Ward Jan 2014

From Battery Cages To Barns: A Cost-Benefit Analysis Of A National Standard For Cage-Free Egg Production, Jonathan Ward

School of Public Policy Capstones

Legislation concerning the well being of farm animals has become a major focus in the animal rights movement, especially as it pertains to intensive confinement systems, such as housing egg-laying hens in battery cages. Informational asymmetries in the market for eggs represent a market failure, as producers have few incentives to inform consumers on modern egg production methods, which they may perceive as cruel. This study uses cost-benefit analysis to examine the effects of a hypothetical U.S. ban on caged egg production to assess whether such a standard would produce use and non-use benefits in excess of producer and consumer …
