A Conservation Model: Costa Rican Conservation Strategies Effectively Preserve Their Threatened Primates, Ryan Belmont
A Conservation Model: Costa Rican Conservation Strategies Effectively Preserve Their Threatened Primates, Ryan Belmont
Regis University Student Publications (comprehensive collection)
The wildlife of Costa Rica has experienced various anthropogenic threats over the last century including climate change and agricultural expansion. The mantled howler monkey (Alloutta palliata), Central American spider monkey (Ateles geoffroyi), white-faced capuchin (Cebus imitator), and the Central American squirrel monkey (Saimiri oerstedii) are Costa Rica’s native primates that face several anthropogenic threats such as deforestation for agriculture and climate change. In response to increased threats to its four native species of non-human primates, Costa Rica has implemented effective governmental conservation tactics such as the Payments for Environmental Services program, ecotourism …
Towards Environmental Sustainability Of Nanotechnology Through Improved Evaluations Of Impact And Risk To Aquatic Species: Cross-Species Comparisons From The Laboratory And Environmentally Realistic Exposure Scenarios In The Field, Becky J. Curtis
Theses and Dissertations
Engineered nanomaterials (ENMs) are utilized in a wide variety of applications and products, including everything from toothpaste and personal care products to industries such as aerospace, defense, medicine, electronics, and agriculture. Depending on the application, release of ENMs to the environment may occur through both unintentional and deliberate routes. High surface-area-to-volume ratios make ENMs more volatile than bulk counterparts, and their small size allows translocation within biological systems that would not be possible with larger materials. These and other characteristics make ENM-biological system interactions unpredictable, creating uncertainty about their potential risks to environmental health. The purpose of this research is …

Sustainable Agriculture: How France Promotes Sustainability, Jordan Pulling
Honors Theses
High consumption lifestyles led to a rapid decline in natural resources. The daily gestures of the people of the world use a quantity massive resource and energy that cannot be replaced. Decision makers of the world are invited to consider what changes will be needed to focus about sustainable and sustainable practices if we want to continue living in the way which we have become accustomed to. The development of renewable energies was a first step towards total sustainable development. Recently, however, we have seen a new way to reduce negative impacts on the rights of the Earth: changes in …
Investigating The Suitability Of The Crayfish Metabolome As A Bioindicator Of Stream Conditions, Natalie M. Izral
Investigating The Suitability Of The Crayfish Metabolome As A Bioindicator Of Stream Conditions, Natalie M. Izral
Electronic Thesis and Dissertation Repository
The suitability of the crayfish metabolome as a bioindicator of stream conditions was investigated because there is a need for fast responding, sensitive, diagnostic, and ecologically relevant bioindicators. A laboratory study assessed Procambarus clarkii metabolome sensitivity to six different treatments of food or DO stress. A field study in subcatchments of the Red River Valley, Manitoba, Canada assessed the effects of land-use type (reference, agriculture, wastewater effluent) on the Orconectes virilis metabolome. Crayfish were sacrificed, and hepatopancreas, gill, and tail tissues were dissected. Analyses found the metabolome was sensitive enough to potentially diagnose food and DO stress in P. clarkii …
