Book Description
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.

Book Description
Since 1973, tens of thousands of first-time and experienced beekeepers alike have relied on The Beekeeper's Handbook as the best single-volume guide to the hobby and profession of beekeeping. Featuring clear descriptions and authoritative content, this handbook provides step-by-step directions accompanied by more than 100 illustrations for setting up an apiary, handling bees, and working throughout the season to maintain a healthy colony of bees and a generous supply of honey. This book explains the various colony care options and techniques, noting advantages and disadvantages, so that beekeepers can make the best choices for their own hives. This fourth edition has been thoroughly redesigned, expanded, updated, and revised to incorporate the latest information on Colony Collapse Disorder, green IPM methods, regional overwintering protocols, and procedures for handling bees and managing diseases and pests such as African honey bees and bee mites. The book explains not only how but also why each step is part of the transformative process that results in the magnificent creation of honey. This essential guide is a beekeeper's most valuable resource. Colony Collapse Disorder has renewed our recognition of the importance of small-scale beekeeping and the critical role of bees in the production of our food supply. For the growing number of beekeepers looking to set up hives for either a rewarding hobby or a profitable commercial enterprise, this updated and revised essential how-to guide includes: step-by-step directions for all stages from setting up an apiary to harvesting honey; approximately 100 illustrations featuring techniques, equipment, and bee biology; information about how to manage new pests and diseases including Colony Collapse Disorder; coverage of new trends and changes in beekeeping including green IPM techniques and new laws for urban beekeeping; the most up-to-date bibliography and list of resources on the topic; and a new user-friendly book design that clearly highlights instructions and other important features.

Book Description
Biotechnological methods are opening new ways in plant breeding. They allow novel strategies for improving crop productivity and quality, especially in the agrofood sector. The molecular mechanisms underlying these biotechnological approaches are presented here. Topics included are: pollen development, pollen tube growth, macrosporogenesis and fertilization and the effects of pesticides on sexual plant reproduction. Fertilization in higher plants is a complex process consisting of two events, the fusion of the egg with one sperm cell resulting in the diploid zygote, and the fusion of embryosac nuclei with another sperm cell, leading to a triploid endosperm. This "double fertilization" is preceded by the pollination process and a long lasting interaction between the dipoid pistil and the haploid pollen tube (progamic phase). Fertilization of flowering plants results in the formation of seeds and fruits, our basic food supply.

Book Description
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.

Book Description
A fundamental aspect of the work of ecosystem restoration is to rediscover the past and bring it into the present-to determine what needs to be restored, why it was lost, and how best to make it live again. This handbook makes essential connections between past and future ecosystems, bringing together leading experts to offer a much-needed introduction to the field of historical ecology and its practical application by on-the-ground restorationists. - from publisher description.

Book Description
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.

Book Description
The dominant trees of Australia, eucalypts make up a remarkable genus. This authoritative volume provides current reviews by active researchers of many disciplines, including evolutionary history, genetics, distribution and modelling, the relationship of eucalypts to fire and nutrients, ecophysiology, pollination and reproductive ecology, interactions between eucalypts and other co-existing biota (including fungi, invertebrates and vertebrates), and conservation and management. Together these reviews shed light on the reasons for the great success of eucalypts in Australian environments, and provide a comprehensive summary for comparison with the ecology of major woody plant genera in other continents. This volume is of particular relevance to Australian ecologists, but also provides a stimulating perspective to students of vegetation ecology in all continents.
