Download or read book Landscape Effects on Bee Pollinators in a Tropical Agroecosystem written by Levi Keesecker and published by . This book was released on 2017 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land-use change and intensification are among the most important drivers of species loss and the degradation of ecosystem functions. Agricultural areas occupy nearly 40% of the Earth's surface, thus efforts to mitigate the ecological effects of land-use intensification should focus in part on utilizing more sustainable food production practices that enhance species persistence within farms. Bees (superfamily Apoidea) are widely considered the most important pollinators globally for both wild plant pollination and agricultural production. Global declines of managed and wild bees threaten the delivery of pollination services to agriculture. In my first two chapters, I present results of research conducted in a coffee-dominated agricultural landscape in Costa Rica. I explore the extent to which coffee farm intensity (e.g., "sun" coffee vs. "shade" coffee) affects bee community dynamics. Chapter 1 focuses on how land-use intensity mediates the distribution and relative abundance of bee functional traits that are thought to be important for pollination. Chapter 2 explores how land-use context within an agroecosystem affects bee diversity and stability at the community scale. Both functional diversity, and diversity-stability relationships are community patterns that have been demonstrated to have a mechanistic relationship to ecosystem functioning (e.g., pollination). We found that landscape context does influence functional trait distributions and relative abundance in bee communities in a coffee agroecosystem, implying that landscape context moderates the trait composition of bee communities. Further, we found that the traits that responded to landscape elements are traits considered important for delivery of pollination services within farms. We also elucidate how landscape-scale intensification of coffee agroforestry practices reduces community-scale stability of bees by synchronizing their populations through time. My third chapter is framed within the heuristic of "Social-Ecological Systems" as part of the University of Idaho's Integrative Graduate Education and Research Traineeship (IGERT) program. Here my co-authors and I show that natural resource management challenges may be aided by embarking on a thorough exploration of the spatio-temporal scales at which biophysical processes and natural resource governance operate, with an emphasis on spatio-temporal scale "mis-fit" (i.e., when biophysical processes that provision a resource are managed at improper scales).

A Biodiversity Check in Costa Rica written by Moritz Stüber and published by GRIN Verlag. This book was released on 2018-10-15 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (undergraduate) from the year 2018 in the subject Agrarian Studies, grade: 1,7, University of Hohenheim (Zentrum Ökologischer Landbau Universität Hohenheim), language: English, abstract: When it comes to ecological measures and sustainability, Costa Rica (CR) is one of the most developed countries in Latin America. During the past two years CR was able to be nearly 100% eco-power self-sufficient. Moreover it is planning to be the first country worldwide to prohibit disposable plastic and one of the organic pioneers in the region. Organic food export and people’s ecologic awareness have been rising. As the biodiversity in CR is one of the highest worldwide, the country’s nature protection strategy is a topic to focus on and worth to be studied. Latin American studies on organic management as a tool for biodiversity conservation are rare. Organic Agriculture (OA), as written in the IFOAM 1972, always committed to the conservation of biodiversity. There were only few attempts to include biodiversity conservation into the existing organic standards and guidelines. First in 2005, biodiversity conservation, as part of the draft “Biodiversity and Landscape Standards” was mentioned and integrated into the IFOAM Basic Standards. In CR, one of the principal promoters of OA is the CEDECO (Educative Corporation of Development in Costa Rica). Their research often focused on arthropods since many species are known to be biological indicators of an ecosystem’s health status. Exemplary insects of their studies are butterflies or dung beetles. Many birds are insect-/ omnivorous, thus directly linked to arthropod abundance. Organic coffee plantations in CR are tried to be integrated into nature (agroforestry), which results in a different habitat than the conventional ones. Instead of shrub-sized coffee plants, there is a sudden interaction with the canopy and a more diverse shrub-layer. In the following report, the focus will be laid on species that experienced a success story but also those who might not. It will be demonstrated by changes in vegetation, diversity changes above and beneath ground and the way the farmer can profit from each species.

Download or read book Coffee Agroecology written by Ivette Perfecto and published by Routledge. This book was released on 2015-02-11 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on principles of the conservation and optimization of biodiversity and of equity and sustainability, this book focuses on the ecology of the coffee agroecosystem as a model for a sustainable agricultural ecosystem. It draws on the authors' own research conducted over the last twenty years as well as incorporating the vast literature that has been generated on coffee agroecosystems from around the world. The book uses an integrated approach that weaves together various lines of research to understand the ecology of a very diverse tropical agroforestry system. Key concepts explored include biodiversity patterns, metapopulation dynamics and ecological networks. These are all set in a socioeconomic and political framework which relates them to the realities of farmers' livelihoods. The authors provide a novel synthesis that will generate new understanding and can be applied to other examples of sustainable agriculture and food production. This synthesis also explains the ecosystem services provided by the approach, including the economic, fair trade and political aspects surrounding this all-important global commodity.

This book was released on 2011-06-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues In Agroecology – Present Status and Future Prospectus not only reviews aspects of ecology, but the ecology of sustainable food production systems, and related societal and cultural values. To provide effective communication regarding status and advances in this field, this series connects with many disciplines such as sociology, anthropology, environmental sciences, ethics, agriculture, economics, ecology, rural development, sustainability, policy and education, and integrations of these general themes so as to provide integrated points of view that will help lead to a more sustainable construction of values than conventional economics alone. Such designs are inherently complex and dynamic, and go beyond the individual farm to include landscapes, communities, and biogeographic regions by emphasizing their unique agricultural and ecological values, and their biological, societal, and cultural components and processes.

Book excerpt: The herbaceous community (HC) is an understudied yet critical aspect of tropical agroecosystems. I measured the diversity and perceptions of the HC within organic coffee systems in the Central Valley of Costa Rica. The HC was taxonomically and functionally diverse; comprised of 39 species from 20 taxonomic groups. Farms below the regional mean size and those with canopy openness of 20-30% had higher HC functional diversity. Farmers perceived tall species with low SLA and LNC, but high height and LDMC to be undesirable, due to slow decomposition rates and management limitations. Farmers' cognitive map complexity was positively related to HC functional richness, and negatively related to functional evenness and functional dissimilarity. All farmers placed higher emphasis on soil health and organic matter than coffee yield, which may be indicative of their role as land stewards. Workshops are needed to disseminate HC management information to optimize labour and ecosystem functioning.

This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
