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 Bee Basics written by Stephen Buchmann and published by Government Printing Office. This book was released on 2015-09-16 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native bees are a hidden treasure. From alpine meadows in the national forests of the Rocky Mountains to the Sonoran Desert in the Coronado National Forest in Arizona and from the boreal forests of the Tongass National Forest in Alaska to the Ocala National Forest in Florida, bees can be found anywhere in North America, where flowers bloom. From forests to farms, from cities to wildlands, there are 4,000 native bee species in the United States, from the tiny Perdita minima to large carpenter bees. This illustrated and colorful pamphlet provides valued information about native bees --over 4,000 in population --varying in a wide array of sizes, shapes, and colors. They are also different in their life styles, the places they frequent, the nests they build, the flowers they visit, and their season of activity. Yet, they all provide an invaluable ecosystem service - pollination -to 80 percent of flowering plants. Blueberry bees, bumble bees, yellow jacket bees, carpenter bees, and more are explored, including the differences in their gender, nests, and geographical regions that they visit.

Download or read book Floral Biology written by M. Percival and published by Elsevier. This book was released on 2013-10-22 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floral Biology attempts to show how floral biologists conduct their experiments and what techniques they employ in floral biology. The techniques employed include those of physics, chemistry, physiology, psychology, genetics, and ecology, and so constitute a broad training in biology that may be useful and acceptable in other fields. Organized into 11 chapters, this book begins with a discussion on sex in flowers; the biology of the floral parts; agencies of pollination; and the pollen, nectar, and nectaries. Some chapters follow on pollination by birds, bats, and insects. The features of entomophilous flowers and isolating mechanisms in flowers are also described. Some hints for students, such as the tools required, how to make them, and a schedule of procedure for examining the floral biology of a species, are given in the last chapter. This book will attract workers, who, armed with the techniques and stimulated by the findings of the investigators, can introduce the floral biology to other fields.
Download or read book Honeybee Ecology written by Thomas D. Seeley and published by Princeton University Press. This book was released on 2025-03-11 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the acclaimed author of Honeybee Democracy, a classic account of the ecological factors that shape the social lives of honeybees For many years, research on honeybee social life dealt primarily with the physiological processes underlying the social system of the bee rather than the ecological factors that have shaped its societies. Thomas Seeley’s landmark book unites the two approaches, emphasizing ecological studies of honeybee social behavior while also offering fresh perspectives on honeybee behavior and communication. It covers a broad range of topics, from adaptiveness of worker sterility and the economics of nest construction to information-center foraging, individual versus colony level selection, sex ratio evolution, colonial thermoregulation, evolution of colony defense, and adaptive radiation in colony design. Honeybee Ecology presents honeybees as a model system for investigating advanced social life among insects from an evolutionary perspective.

Understanding the biology of flora and its value to honey bees is the core foundation for successful beekeeping. Bees feed on nectar and pollen. No food equals no bees! The flowers on which bees forage have a major impact on stocking rates and the level of nutrition available to the colony, two subjects that need to be understood for a beekeeper to be successful. Whether a beekeeper owns one hive or a thousand, the principle is the same. Floral resources within Australia underpin so many systems and animal species. Building knowledge and understanding of what they are, and how they are adapting to a changing climate, is a critical field of scientific endeavour. This publication is part of the journey to focus on the value of plants to nectarivores and honey bees in particular. The result of over 30 years of research, it distils both scientific knowledge and the opinions of hundreds of beekeepers into a reference work that will be the cornerstone of floral understanding in apiculture for years to come.

Download or read book Pot Pollen in Stingless Bee Melittology written by Patricia Vit and published by Springer. This book was released on 2018-03-05 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers pot-pollen—the other product, besides honey, stored in cerumen pots by Meliponini. Critical assessment is given of stingless bee and pot-pollen biodiversity in the Americas, Africa, Asia and Oceania. Topics addressed include historical biogeography, cultural knowledge, bee foraging behavior, pollination, ecological interactions, health applications, microbiology, the natural history of bee nests, and chemical, bioactive and individual plant components in stored pollen. Pot-pollen maintains the livelihoods of stingless bees and provides many interesting biological products that are just now beginning to be understood. The Meliponini have developed particular nesting biologies, uses of building materials, and an architecture for pollen storage. Environmental windows provide optimal temperature and availability of pollen sources for success in plant pollination and pollen storage. Palynological composition and pollen taxonomy are used to assess stingless honey bee pollination services. Pollen processing with microorganisms in the nest modifies chemical composition and bioactivity, and confers nutraceutical benefits to the honey and pollen widely relished by native people. Humans have always used stingless bees. Yet, sustainable meliponiculture (stingless bee-keeping) projects have so far lacked a treatise on pot-pollen, which experts provide in this transdisciplinary, groundbreaking volume.

Download or read book Honeybee Democracy written by Thomas D. Seeley and published by Princeton University Press. This book was released on 2010-09-20 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: How honeybees make collective decisions—and what we can learn from this amazing democratic process Honeybees make decisions collectively—and democratically. Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, Honeybee Democracy brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees. In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together—as a swirling cloud of bees—to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution. An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.
