Public Perception Of Environmental Programs In The Sierra Gorda Biosphere Reserve, Landa De Matamoros, Queretaro, Mexico, Danielle Marie Salisbury Jan 2017

Public Perception Of Environmental Programs In The Sierra Gorda Biosphere Reserve, Landa De Matamoros, Queretaro, Mexico, Danielle Marie Salisbury

Bard Center for Environmental Policy

Biological or ecological corridors have recently been sought out as a solution to biodiversity loss due to habitat fragmentation. In eastern Mexico, the Mexican and German governments are collaborating to connect fragmented landscapes and Natural Protected Areas (NPAs) over five states across a Madrean Pine-Oak biodiversity hotspot through the implementation of the Ecological Corridor of the Sierra Madre Oriental (CESMO). One of the ways the CESMO is accomplishing its conservation goals is by extending environmental programs that are currently in place within NPAs to other areas within the corridor, but outside of NPA borders. However, the success of the corridor …


Carbon Stocks In Shade Coffee: Strategies For Enhancing Carbon Storage In Smallholder Systems In Jinotega, Nicaragua, Vanessa Katheryn Kichline Jan 2017

Carbon Stocks In Shade Coffee: Strategies For Enhancing Carbon Storage In Smallholder Systems In Jinotega, Nicaragua, Vanessa Katheryn Kichline

Bard Center for Environmental Policy

Climate change has recently shifted focus to adaptation and mitigation strategies in coffee production. Shade coffee systems, already widely recognized for their contribution to biodiversity and soil conservation, are now drawing attention for their role in carbon storage. Researchers have generally assumed that high carbon storage must come at the expense of reduced crop yields, implying that farmers must choose between sustainability and profit. This study uses field inventories of 70 farms in Jinotega, Nicaragua to estimate this tradeoff in smallholder shade coffee systems. Field inventories were used to develop three typologies representing different shade management strategies in use in …


Addressing Antibiotic Resistance From Farm-Raised Fish Imported To The United States, Nicholas Ali Jan 2017

Addressing Antibiotic Resistance From Farm-Raised Fish Imported To The United States, Nicholas Ali

Bard Center for Environmental Policy

Misuse of medically important antibiotics in animal production threatens the effectiveness of drugs that are vital in combating disease and infections. Recently, the FDA implemented regulations to limit the use of and access to veterinary drugs. However, these regulations only affect domestic production operations. Because over 90% of seafood consumed in the U.S. is imported from countries with different regulatory standards and because the U.S. has an import inspection rate of less than 1%, antibiotic resistance stemming from imported aquaculture is still a risk that is not sufficiently accounted for. This research investigates how the U.S. has reacted to the …

Modeling Purple Sea Urchin And California Sheephead Populations In Southern California Kelp Forests, Olivia Rachel Williams Jan 2017

Modeling Purple Sea Urchin And California Sheephead Populations In Southern California Kelp Forests, Olivia Rachel Williams

Senior Projects Spring 2017

In this project I am modelling the predator-prey relationship between California sheephead and purple sea urchin populations, respectively, in kelp forests off the coast of southern California. The Lotka-Volterra equations explain predator-prey relationships in their most basic form. These equations incorporate a set of biological assumptions that can be unrepresentative of many ecological systems. I will consider alternate models that incorporate variations of the Lotka-Volterra model which may better represent the biology of the purple sea urchins and California sheephead. Using biological characteristics of both species in kelp forests, I will set possible and likely parameters and solve for unknown …
