Habitat Associations Of Priority Bird Species And Conservation Value On Small, Diversified Farms In New England, Isabel Brofsky
Habitat Associations Of Priority Bird Species And Conservation Value On Small, Diversified Farms In New England, Isabel Brofsky
Masters Theses
In recent decades, New England agriculture has become increasingly characterized by small, diversified farming operations with values deeply rooted in community and conservation. In sharp contrast to large-scale, high-intensity agriculture currently typified by the majority of North American farms, New England farmers commonly prioritize ecologically beneficial production practices such as reduced chemical inputs, integrated pest management (IPM), low tillage, cover cropping and crop rotation, and retention of natural habitats like woody hedgerows and herbaceous strips. Public support and demand for local, sustainable food, evidenced by the success of CSA (Community Supported Agriculture) in the region, has helped to bolster this …

Journal of Bioresource Management
True morels collected from wild provide an economic source for the rural community of Mankial valley (District Swat, Khyber Pukhtunkhawa, Pakistan). Sale of approximately 334 kg in dry weight of five species of true morels (Morchella conica, M. esculenta, M. deliciosa, M. rotunda and M. semilibera) fetch US$ 57133 (under US$ 2015-16 exchange rate) to Mankial community and generate a revenue of US$ 62935 in Mingora (regional market) and US$ 87011 in Islamabad (national capital) markets. Morchella conica (average annual dry weight harvested 156 kg) has a high market price value (US$ 2964-44616) in all the three markets. …
Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei
Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
A storm surge is a complex phenomenon in which waves, tide and current interact. Even though wind is the predominant force driving the surge, waves and tidal phase are also important factors that influence the mass and momentum transport during the surge. Devastating storm surges often occur in the Bohai Sea, a semi-enclosed shallow sea in North China, due to extreme storms. However, the effects of waves on storm surges in the Bohai Sea have not been quantified and the mechanisms responsible for the higher surges that affect part of the Bohai Sea have not been thoroughly studied. In this …
How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala
How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala
Latin American Studies ETDs
Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …
Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia
Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia
Independent Study Project (ISP) Collection
Insect damage is a major concern for smallholder farmers in developing countries like Tanzania. Synthetic insecticides can tame infestations, however they can be expensive, inaccessible, and their misuse can threaten farmer health and ecological conditions. Botanical insecticides are cheap alternatives to treat infestations while preserving beneficial insects such as pollinators, predators, and parasitoids. This study assesses how both synthetic and botanical insecticides affect beneficial insects, crop yield and profit/costs. This study finds botanical insecticides slightly less harmful towards non-target insects. Botanical insecticides seldomly improve crop yields but usually result in a higher profit/lower cost. Due to high variation in ecological …

New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand
New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand
Animal Sentience
This commentary expands Wiebers & Feigin’s target article by pinpointing how declining wildlife, expanding livestock and globalisation contribute to the increase in epidemics of zoonotic diseases, the COVID-19 crisis and future health crises. Epidemics and the emergence of zoonoses are manifestations of dysfunctional links with animals, both wild and domestic, requiring a new approach to health and the environment.
The Influence Of Land Use On The Pollen Diet Of Honey Bee (Apis Mellifera) Colonies In Ellis County, Kansas, Ryan Engel
The Influence Of Land Use On The Pollen Diet Of Honey Bee (Apis Mellifera) Colonies In Ellis County, Kansas, Ryan Engel
Master's Theses
Pollinators are integral to plant ecology as well as to worldwide food availability and security. Understanding how human-driven land use change impacts the nutrition of managed honey bees is important in pollinator conservation efforts and can contribute towards combating recent pollinator declines. The objective of this study was to determine sources of forage for honey bees across different land use types in Ellis County, Kansas, through pollen analysis and taxonomic identification. Replicate study colonies were placed in three separate land use types: Urban, Cropland, or Native/Semi-native prairie. Pollen was sampled every 7 to 14 days throughout a growing season (April …
