Download or read book Pollen Grains Honeydew written by Margaret Anne Adams and published by . This book was released on 2021-12-07 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes, in detail, a simple approach for beekeepers, to identify the plant sources of their own honey. They will occasionally find they have a special honey, and then the jars can be labelled accordingly. From 2019 to 2021, beekeepers from The UK and Continental Europe sent me samples of their honey, and the collection of digital photos from my own pollen slides, helped me to identify most of the pollens in their honey. These pollens and the honeydews found in most summer honey, feature in this book. Christine Coulsting has contributed a section, describing how she deals with identifying pollens, found in her honey, but not in her pollen slide collection. Alan Riach's section details the calculations needed to proportion the pollens found in a sample of honey, to the flowers' nectar contributions.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a growing awareness of the importance of reproductive biology to crop production and there has been a tremendous increase in research on reproductive structures of higher plants. Presented here is a wide information of different aspects of micro- and macrosporogenesis, pollen-stigma interaction and recognition, pollen tube growth, cytoskeleton, in vitro and in vivo gamete fusion, and incompatibility. The most advanced techniques employed in studies on reproductive biology of higher plants are described in detail.
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 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 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.
Download or read book The Dictionary of Science for Gardeners written by Michael Allaby and published by Timber Press. This book was released on 2015-09-05 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Library Journal Best Reference Pick of 2015! Every gardener is a scientist. Pollination, native plants, ecology, climatology—these are just a few of the scientific concepts that play a key role in a successful garden. While the ideas are intuitive to many gardeners, they are often discussed in unfamiliar scientific terms. The Dictionary of Science for Gardeners is the first of its kind to provide practical scientific descriptions for gardening terms. Highlighting 16 branches of science that are of particular interest to gardeners, with entries from abaptation to zoochory, Michael Allaby explores more than 6,000 terms in one easy-to-use reference.
