Developing Resources To Foster Farmed Animal Agency In Sanctuary Education, Emily Tronetti
Developing Resources To Foster Farmed Animal Agency In Sanctuary Education, Emily Tronetti
Antioch University Dissertations & Theses
Farmed animal sanctuaries provide lifelong care to formerly farmed animals. Many strive to educate their community about farmed animals and promote more compassionate lifestyles, such as veganism. Important to this is cultivating empathy and concern for the well-being of individual farmed animals. Essential to well-being is agency, which is the capacity of a living being to engage with their environments and to make choices for themselves. Farmed animals outside of sanctuaries have had their agency systematically suppressed and denied. Sanctuary educators can bring awareness to this and inspire alternative, agency-centered relationships with not only farmed animals but all living beings. …
Habitat Characteristics And Nesting Ecology Of Golden Eagles In Arizona, Michele J. Losee
Habitat Characteristics And Nesting Ecology Of Golden Eagles In Arizona, Michele J. Losee
Antioch University Dissertations & Theses
Golden Eagles (Aquila chrysaetos) have a broad range globally and in general are well-studied. However, Arizona’s Golden Eagle population remained essentially unstudied until 2011, when Arizona Game and Fish Department (AZGFD) began nest surveys for cliff nesting Golden Eagles throughout the state. As a result of this data collection, the natural history of Arizona’s Golden Eagles is finally revealing itself. This dissertation outlined a reliable description of their nesting phenology that provides a framework for timing surveys and a baseline to monitor the effects of climate change on Golden Eagles. The mean date for egg-laying was February 14 and pairs …
A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead
A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead
Antioch University Dissertations & Theses
Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …
Scales Of Resilience: Community Stability, Population Dynamics, And Molecular Ecology Of Brook Trout In A Riverscape After A Large Flood, Erin V. Rodgers
Scales Of Resilience: Community Stability, Population Dynamics, And Molecular Ecology Of Brook Trout In A Riverscape After A Large Flood, Erin V. Rodgers
Antioch University Dissertations & Theses
Climate change in the northeastern United States currently and in future decadal predictions is characterized by warmer average temperatures and more frequent and intense storm events. Many aquatic organisms that thrive below a certain temperature threshold, such as brook trout, are being pushed towards their upper thermal limits, ultimately lowering their probability of survival and resilience to disturbance. In late-August and early-September 2011, Hurricane Irene and Tropical Storm Lee created an extended flood in the Delaware Water Gap region of Pennsylvania and New Jersey, as well as much of the northeast. This dissertation examines the effects of this flood on …
Ramapough/Ford The Impact And Survival Of An Indigenous Community In The Shadow Of Ford Motor Company’S Toxic Legacy, Chuck Stead
Ramapough/Ford The Impact And Survival Of An Indigenous Community In The Shadow Of Ford Motor Company’S Toxic Legacy, Chuck Stead
Antioch University Dissertations & Theses
The purpose of this study was to examine the history of the Ford Motor Company’s impact upon the Ramapo Watershed of New York and New Jersey, as well as upon the Ramapough Munsi Nation, an indigenous population living there. In a 25 year span the automaker produced a record number of vehicles and dumped a massive amount of lead paint, leaving behind a toxic legacy that continues to plaque the area and its residents. The Ramapough people are not unlike many native nations living in the United States who have experienced industrial excess. This study examines the mindset that allows …
Matrix And Edge Effects On The Maintenance Of Ecological Function In An Afromontane Protected Area, Robin M. Martino
Matrix And Edge Effects On The Maintenance Of Ecological Function In An Afromontane Protected Area, Robin M. Martino
Antioch University Dissertations & Theses
Land use type in the human dominated matrix surrounding tropical forest can influence edge effects at the forest-matrix interface. Edge effects can alter ecological processes and impact the function of forest edge ecosystems. A key ecological process that helps maintain tropical forest and is affected by forest disturbance is seed dispersal by large, fruit eating vertebrates (frugivores). This dissertation examines how the type of vegetation in the matrix, the `soft’ edge contrast of pine plantations and the `hard’ edge contrast of tea plantations, affect seed dispersal behavior of large frugivores, and the structure and composition of tree species, in forest …
Humane Education: Perspectives Of Practitioners On Program Evaluation Efforts And Analysis Of Changes In Knowledge, Attitudes, And Empathy In Two Violence Prevention And Intervention Programs, Melanie Wagner
Antioch University Dissertations & Theses
This descriptive and comparative study examined the current landscape of humane education program evaluation and data analysis through a survey of humane educators across the country. Results of the humane education survey show that data collection and evaluation are occurring in humane education programs but these efforts do not capture and measure empathy, the primary goal of most humane education programs. Humane educators reported they felt the profession is progressive and relevant to a broad host of purposes, from building positive relationships with animals to playing a role in the larger social justice scheme. They also suggested that the field …
Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, Mark Stephen Mcreynolds
Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, Mark Stephen Mcreynolds
Antioch University Dissertations & Theses
This study was conducted in 2008 and 2009 to determine if Scarlet Macaws (Ara macao), in subtropical southern Belize, Central America, are seasonal and elevational migrants and if their movement is influenced by seasonally abundant food. Reports from southern Belize indicated strongly seasonal sightings of macaws (N ≈ 200) in two separate areas of considerable difference in elevation. I monitored plant phenology plots (2 m x 500 m) in low (N = 6) and high (N = 6) elevation areas for a year to compare fruit abundance with macaw sightings in point counts on the plots and nearby. My point …
The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster
The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster
Antioch University Dissertations & Theses
The development of management programs for socio-ecological systems that include multiple stakeholders is a complex process and requires careful evaluation and planning. This is particularly a challenge in the presence of intractable conflict. The feral pig (Sus scrofa) in Australia is part of one such socio-ecological system. There is a large and heterogeneous group of stakeholders interested in pig management. Pigs have diverse effects on wildlife and plant ecology, economic, health, and social sectors. This study used the feral pig management system as a vehicle to examine intractable conflict in socio-ecological systems. The purpose of the study was …
Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones
Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones
Antioch University Dissertations & Theses
This study examined whether female reproductive class (i.e., presence or absence of a calf) in humpback whales (Megaptera novaeangliae) affects female behavior and male-female interactions on the Hawaiian breeding grounds. From 2003-2008, 295 female-calf groups (with or without a male escort) and 256 female no-calf groups (with a male) were observed. Forty-one female no-calf groups were confirmed male-female pairs by genetic sexing or photo-identification. Focal follows of 36 male-female pairs and 50 female-calf groups (29 escorted and 21 unescorted female-calf groups) were analyzed for time budget and movement estimates. Relative fluke size (fluke photogrammetry, n=30) and sighting histories …
Dispersion Of Large-Seeded Tree Species By Two Forest Primates: Primate Seed Handling, Microhabitat Variability, And Post-Dispersal Seed Fate, Nicole D. Gross-Camp
Dispersion Of Large-Seeded Tree Species By Two Forest Primates: Primate Seed Handling, Microhabitat Variability, And Post-Dispersal Seed Fate, Nicole D. Gross-Camp
Antioch University Dissertations & Theses
I describe the relative effectiveness of two primates in dispersing large-seeded tree seeds (> 0.5 cm) in the Nyungwe National Park (NNP), Rwanda. My objectives are three-fold: (1) to describe the relative effectiveness of primates in dispersing the seeds of five large-seeded tree species, (2) to evaluate the influence of primate seed-handling method on seed fate, and (3) to determine the influence of deposition site on seed fate. I employed focal tree observations, day-follows of habituated primate groups, in situ monitoring of primate-dispersed seeds, and experimental plots to achieve these objectives. Data were collected over the course of one year …
