This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees (Apis mellifera) provide pollination services for many crops globally, but extreme weather and changing temperatures due to climate change may threaten the health of this species. Although we know that honey bee survival can decrease due to thermal stress, we know less about how thermal stress affects feral honey bees given that they are potentially adapted to higher temperatures in certain climates. Our research investigated the effect of extreme heat and cold on feral and managed honey bees in San Diego County, California. In this region, managed honey bees are pure European Apis mellifera, while the majority of feral honey bees are genetically admixed with Apis mellifera scutellata, from Africa, which are thought to be limited in their range by cold and to be more tolerant of heat. We measured individual survival between feral and managed honey bees after exposure to incubator heat shock or cold shock, critical thermal maxima and minima, and chill coma recovery time. Feral bees had higher survival compared to managed bees following heat shock or cold shock, but they did not differ with respect to CTmax, CTmin, or chill coma recovery time, suggesting that the effects of temperature upon survival require some time to manifest. Thus, the range of scutellata hybrids may not be constrained by individual survival following cold exposure but by colony-level effects or broader environmental effects linked with colder climates. These hybrids are, however, evidently better adapted to warmer conditions compared to pure European honey bees.

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. 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.

Download or read book Linking Government Data written by David Wood and published by Springer Science & Business Media. This book was released on 2011-11-12 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linking Government Data provides a practical approach to addressing common information management issues. The approaches taken are based on international standards of the World Wide Web Consortium. Linking Government Data gives both the costs and benefits of using linked data techniques with government data; describes how agencies can fulfill their missions with less cost; and recommends how intra-agency culture must change to allow public presentation of linked data. Case studies from early adopters of linked data approaches in international governments are presented in the last section of the book. Linking Government Data is designed as a professional book for those working in Semantic Web research and standards development, and for early adopters of Semantic Web standards and techniques. Enterprise architects, project managers and application developers in commercial, not-for-profit and government organizations concerned with scalability, flexibility and robustness of information management systems will also find this book valuable. Students focused on computer science and business management will also find value in this book.
Download or read book Bee Pollination in Agricultural Ecosystems written by Rosalind James and published by Oxford University Press. This book was released on 2008-09-09 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many agricultural crops, bees play a vital role as pollinators, and this book discusses the interplay among bees, agriculture, and the environment. Although honey bees are well recognized as pollinators, managed bumble bees and solitary bees are also critical for the successful pollination of certain crops, while wild bees provide a free service. As bees liberally pass pollen from one plant to the next, they also impact the broader ecosystem, and not always to the benefit of humankind. Bees can enhance the unintentional spread of genes from genetically engineered plants, and may increase the spread of invasive weeds. Conversely, genetically engineered plants can impact pollinators, and invasive weeds can supply new sources of food for these insects. Bees' flower-visiting activities also can be exploited to help spread biological control agents that control crop pests, and they are important for native plant reproduction. Managing bees for pollination is complex and the factors that must be taken into consideration are treated here, including bee natural history, physiology, pathology, and behavior. Furthermore, transporting bees from native ranges to new areas for pollination services can be controversial, and needs to be done only after assuring that it will not disrupt various ecosystems. Even though bees are small, unobtrusive creatures, they play large roles in the ecosystem. The connection between bees and humankind also is symbolic of a broader interconnection between humans and the natural world.
Download or read book Hymenoptera and Conservation written by T. R. New and published by John Wiley & Sons. This book was released on 2012-07-02 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hymenoptera, the bees, wasps and ant, are one of the largest insect orders, and have massive ecological importance as pollinators and as predators or parasitoids of other insects. These roles have brought them forcefully to human notice , as governors of some key ecological services that strongly influence human food supply. Recent declines of pollinators and introductions of alien pests or biological control agents are only part of the current concerns for conservation of Hymenoptera, and of the interactions in which they participate in almost all terrestrial ecosystems. Both pests and beneficial species abound within the order, sometimes closely related within the same families. Many taxa are both difficult to identify, and very poorly known. This global overview, the first such account for the whole of the Hymenoptera, discusses a broad range of themes to introduce the insects and their conservation roles and needs, and how their wellbeing may be approached. The book is intended as a source of information for research workers, students, conservation managers and naturalists as an introduction to the importance of this dominant insect order.
Download or read book The Impact of the European Honey Bee Apis Mellifera on Australian Native Bees written by Dean Paini and published by . This book was released on 2004 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European honey bee (Apis mellifera) has been present in Australia for approximately 150 years. For the majority of that time it was assumed this species could only be of benefit to Australia‘s natural ecosystems. More recently however, researchers and conservationists have questioned this assumption. Honey bees are an introduced species and may be affecting native fauna and flora. In particular, native bees have been highlighted as an animal that may be experiencing competition from honey bees as they are of similar sizes and both species require nectar and pollen for their progeny. Most research to date has focused on indirect measures of competition between honey bees and native bees (resource overlap, visitation rates and resource harvesting). The first chapter of this thesis reviews previous research explaining that many experiments lack significant replication and indirect measures of competition cannot evaluate the impact of honey bees on native bee fecundity or survival. Chapters two and four present descriptions of nesting biology of the two native bee species studied (Hylaeus alcyoneus and an undescribed Megachile sp.). Data collected focused on native bee fecundity and included nesting season, progeny mass, number of progeny per nest, sex ratio and parasitoids. This information provided a picture of the nesting biology of these two species and assisted in determining the design of an appropriate experiment. Chapters three and five present the results of two experiments investigating the impact of honey bees on these two species of native bees in the Northern Beekeepers Nature Reserve in Western Australia. Both experiments focused on the fecundity of these native bee species in response to honey bees and also had more replication than any other previous experiment in Australia of similar design. The first experiment (Chapter three), over two seasons, investigated the impact of commercial honey bees on Hylaeus alcyoneus, a native solitary bee. The experiment was monitored every 3-4 weeks (measurement interval). However, beekeepers did not agist hives on sites simultaneously so measurement intervals were initially treated separately using ANOVA. Results showed no impact of honey bees at any measurement interval and in some cases, poor power. Data from both seasons was combined in a Wilcoxon‘s sign test and showed that honey bees had a negative impact on the number of nests completed by H. alcyoneus. The second experiment (Chapter 5) investigated the impact of feral honey bees on an undescribed Megachile species. Hive honey bees were used to simulate feral levels of honey bees in a BACI (Before/After, Control/Impact) design experiment. There was no impact detected on any fecundity variables. The sensitivity of the experiment was calculated and in three fecundity variables (male and female progeny mass and the number of progeny per nest) the experiment was sensitive enough to detect 15-30% difference between control and impact sites. The final chapter (Chapter six) makes a number of research and management recommendations in light of the research findings.

Available in PDF, EPUB and Kindle. Book excerpt: Consider this: Without interaction between animals and flowering plants, the seeds and fruits that make up nearly eighty percent of the human diet would not exist. In The Forgotten Pollinators, Stephen L. Buchmann, one of the world's leading authorities on bees and pollination, and Gary Paul Nabhan, award-winning writer and renowned crop ecologist, explore the vital but little-appreciated relationship between plants and the animals they depend on for reproduction -- bees, beetles, butterflies, hummingbirds, moths, bats, and countless other animals, some widely recognized and other almost unknown. Scenes from around the globe -- examining island flora and fauna on the Galapagos, counting bees in the Panamanian rain forest, witnessing an ancient honey-hunting ritual in Malaysia -- bring to life the hidden relationships between plants and animals, and demonstrate the ways in which human society affects and is affected by those relationships. Buchmann and Nabhan combine vignettes from the field with expository discussions of ecology, botany, and crop science to present a lively and fascinating account of the ecological and cultural context of plant-pollinator relationships. More than any other natural process, plant-pollinator relationships offer vivid examples of the connections between endangered species and threatened habitats. The authors explain how human-induced changes in pollinator populations -- caused by overuse of chemical pesticides, unbridled development, and conversion of natural areas into monocultural cropland-can have a ripple effect on disparate species, ultimately leading to a "cascade of linked extinctions."
Download or read book Pollination Biology written by Dharam P. Abrol and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.
