This book was released on 2019 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild and managed bees are the most effective pollinators, accounting for about 80% of the pollination of flowering plants and 75% of fruits, nuts, and vegetables in the United States (USDA, 2019; USFWS, 2019). An estimated 4,000 species of bees reside in North America, the majority of which are wild and unmanaged. Wild bee communities are critical for maintaining healthy ecosystems, as they sustain native flora that provides soil stability and habitat for other wildlife. In a changing landscape, floral enhancements on privately and publicly-owned lands may have great impact for improving habitat for pollinators across the United States. Planting diverse flowering vegetation on otherwise low-yielding farmland provides refuge for wildlife and can help connect fragmented habitats when combined with other conservation efforts. Further, planting pollinator-friendly native wildflowers on roadsides provides nutrient-rich forage and nesting resources for bees and is aesthetically pleasing to humans. This thesis focuses on the impact of habitat enhancements on private agricultural margins and public roadsides on wild bee communities by reviewing the current literature on bee decline and pollinator habitats (chapter 1), examining the effect of establishing conservation habitats in private pivot-irrigated crop fields (chapter 2) and public roadsides (chapter 3), and synthesizing best management recommendations and current available conservation programs for landowners and managers (chapter 4). In chapter 2, pivot corners planted to habitat (HC) had significantly higher bee abundance compared to all non-corner locations as well as significantly higher bee richness compared to all non-corner location in mid & late seasons. In chapter 3, conventional roadside seeding methods had lower abundance and richness for forbs & bees compared to wildflower only treatments. Roughly 50% of seeded forbs established during the first two years. Bee richness on the roadside plots was highest in the late season, while forb abundance and richness were highest in the mid-season. This research demonstrates that planting high diversity vegetation on underutilized and low-yielding farmland and roadsides can have positive impacts on wild bee pollinator communities and further provides recommendations on how to better manage these lands to promote and sustain wild bee communities.
Download or read book Pollinators and Pollinator Habitat on Federal Lands written by Casey Roberts and published by . This book was released on 2016 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators are essential to the United States economy. Honey bees, native bees, birds, bats, butterflies, and other species contribute substantially to our food production systems, the economic vitality of the agricultural sector, and the health of the environment. On June 20, 2014, the President issued a memorandum directing the heads of executive departments and agencies to create a Federal strategy promoting the health of honey bees and other pollinators. The Presidential Memorandum envisioned broad engagement to improve the management of Federal buildings, landscapes, rangelands and forests to increase and improve pollinator habitat nationally. The objective of this book is to consolidate general information about practices and procedures to use when considering pollinator needs in project development and management of Federal lands that are managed for native diversity and multiple uses. This book also provides guidance and recommendations for creating and maintaining quality habitats for pollinators in new construction, building renovations, landscaping improvements, and in facility leasing agreements at Federal facilities and on Federal lands.
Download or read book Effects of Habitat Restoration on Wild Bee Communities written by Rebecca K. Tonietto and published by . This book was released on 2015 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Declines of honeybees and certain native bees have been reported over the past decades. To avoid losses of bee diversity and pollination services, bee conservation and restoration ecology must find common ground. The current approach to bee conservation consists largely of small-scale habitat enhancement. Restoration, while mainly botanically focused, may function as the ‘tide that raises all ships.’ Alternatively, techniques employed in restoration may function as disturbances from the perspective of bees (e.g., prescribed fire may reduce resources for bees that nest in wood). I conducted a meta-analysis in Chapter 1 to investigate bees’ responses to restoration and specific management actions. Overall, restoration was beneficial in terms of bee abundance and richness. In Chapter 2, I report results from a field study in a chronosequence of prairie restorations in northeastern Illinois. Though unrestored abandoned agricultural fiends, restored prairies, and remnant prairies has similar bee abundance and taxonomic diversity, community composition substantially differed by site type. Analyses of bees’ traits revealed bee communities of restorations were more differentiated than expectations based on null model predictions. My results indicate bee communities were not systematically filtered by disturbances associated with restoration, rather patterns appeared to be driven by stochastic processes, i.e., founder effects. In Chapter 3, I further investigated my findings from a phylogenetic perspective. Phylogenetic data are increasingly used in ecological studies on the basis that species’ similarity in trait space is correlated with evolutionary relatedness. I found key ecological traits in bees showed significant phylogenetic signal (clustering), indicating that phylogeny could be used to inform understanding of bee communities. Bee communities exhibited random phylogenetic structure based on metrics of alpha diversity. Metrics of beta diversity revealed significant phylogenetic clustering at the site level in unrestored and restored prairies. My results based on functional and phylogenetic analyses suggest bee community assembly in restored grasslands can be attributed to stochastic, rather than deterministic events, consistent with founder effects, not environmental filtering. In order to best conserve wild bee communities, proximity to source populations should be considered in the planning stages of new restoration projects.

Download or read book Buzz written by Thor Hanson and published by Basic Books. This book was released on 2018-07-10 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: As seen on PBS's American Spring LIVE, the award-winning author of The Triumph of Seeds and Feathers presents a natural and cultural history of bees: the buzzing wee beasties that make the world go round. Bees are like oxygen: ubiquitous, essential, and, for the most part, unseen. While we might overlook them, they lie at the heart of relationships that bind the human and natural worlds. In Buzz, the beloved Thor Hanson takes us on a journey that begins 125 million years ago, when a wasp first dared to feed pollen to its young. From honeybees and bumbles to lesser-known diggers, miners, leafcutters, and masons, bees have long been central to our harvests, our mythologies, and our very existence. They've given us sweetness and light, the beauty of flowers, and as much as a third of the foodstuffs we eat. And, alarmingly, they are at risk of disappearing. As informative and enchanting as the waggle dance of a honeybee, Buzz shows us why all bees are wonders to celebrate and protect. Read this book and you'll never overlook them again.

Download or read book Evaluating and Conserving Green Infrastructure Across the Landscape written by Karen Firehock and published by . This book was released on 2013-04-30 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the New York State edition of the GIC's guide to evaluating and conserving green infrastructure (GI) across the landscape. It provides an historical background to GI, as well as practical steps for creating GI maps and plans for a community. It discusses issues around evaluating green assets, public involvement in the mapping process, and the practical steps in bringing together GIS information into a useful format. It draws from twelve field tests GIC has conducted over the past six years in a diversity of ecological and political conditions, at multiple scales, and in varied development patterns – from wildlands and rural areas to suburbs, cities and towns. This guide is intended to help people make land management decisions which recognize the interdependence of healthy people, strong economies and a vibrant, intact and biologically diverse landscape. Green infrastructure consists of our environmental assets – which GIC also calls ‘natural assets’ – and they should be included in planning processes. Planning to conserve or restore green infrastructure ensures that communities can be vibrant, healthful and resilient. Having clean air and water, as well as nature-based recreation, attractive views and abundant local food, depends upon considering our environmental assets as part of everyday planning.

Download or read book Monarchs in a Changing World written by Karen S. Oberhauser and published by Cornell University Press. This book was released on 2015-11-16 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monarch butterflies are among the most popular insect species in the world and are an icon for conservation groups and environmental education programs. Monarch caterpillars and adults are easily recognizable as welcome visitors to gardens in North America and beyond, and their spectacular migration in eastern North America (from breeding locations in Canada and the United States to overwintering sites in Mexico) has captured the imagination of the public. Monarch migration, behavior, and chemical ecology have been studied for decades. Yet many aspects of monarch biology have come to light in only the past few years. These aspects include questions regarding large-scale trends in monarch population sizes, monarch interactions with pathogens and insect predators, and monarch molecular genetics and large-scale evolution. A growing number of current research findings build on the observations of citizen scientists, who monitor monarch migration, reproduction, survival, and disease. Monarchs face new threats from humans as they navigate a changing landscape marked by deforestation, pesticides, genetically modified crops, and a changing climate, all of which place the future of monarchs and their amazing migration in peril. To meet the demand for a timely synthesis of monarch biology, conservation and outreach, Monarchs in a Changing World summarizes recent developments in scientific research, highlights challenges and responses to threats to monarch conservation, and showcases the many ways that monarchs are used in citizen science programs, outreach, and education. It examines issues pertaining to the eastern and western North American migratory populations, as well as to monarchs in South America, the Pacific and Caribbean Islands, and Europe. The target audience includes entomologists, population biologists, conservation policymakers, and K–12 teachers.
Download or read book Moral Ecology of a Forest written by José E. Martínez-Reyes and published by University of Arizona Press. This book was released on 2016-11-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests are alive, filled with rich, biologically complex life forms and the interrelationships of multiple species and materials. Vulnerable to a host of changing conditions in this global era, forests are in peril as never before. New markets in carbon and environmental services attract speculators. In the name of conservation, such speculators attempt to undermine local land control in these desirable areas. Moral Ecology of a Forest provides an ethnographic account of conservation politics, particularly the conflict between Western conservation and Mayan ontological ecology. The difficult interactions of the Maya of central Quintana Roo, Mexico, for example, or the Mayan communities of the Sain Ka’an Biosphere, demonstrate the clashing interests with Western biodiversity conservation initiatives. The conflicts within the forest of Quintana Roo represent the outcome of nature in this global era, where the forces of land grabbing, conservation promotion and organizations, and capitalism vie for control of forests and land. Forests pose living questions. In addition to the ever-thrilling biology of interdependent species, forests raise questions in the sphere of political economy, and thus raise cultural and moral questions. The economic aspects focus on the power dynamics and ideological perspectives over who controls, uses, exploits, or preserves those life forms and landscapes. The cultural and moral issues focus on the symbolic meanings, forms of knowledge, and obligations that people of different backgrounds, ethnicities, and classes have constructed in relation to their lands. The Maya Forest of Quintana Roo is a historically disputed place in which these three questions come together.
