Available in PDF, EPUB and Kindle. Book excerpt: Pollination is one of the longest recognized and most important mutualisms. Without pollination services, terrestrial ecosystems would be dramatically simpler and less productive; indeed, many plants today require active pollination to reproduce. Bees, an effective group of pollinators, collect pollen resources to fortify their diet and to feed larvae. In temperate regions, the seasonal mutualistic relationship between plants and pollinators is particularly critical. During spring, trees, shrubs and ephemeral wildflowers are dependent on the parallel emergence of their flowers and bee pollinators for successful reproduction. This association is reciprocal, as bees rely on the emergence of floral resources for energy and protein to initiate their seasonal reproduction. Due to many factors including declines in habitat and floral resources, bees are facing global decreases in numbers and diversity. Declining bee populations impair pollination services, which can lead to diminished agricultural crop yields and reduced ecosystem productivity. This research provides a catalogue of spring pollen loads collected by bees in the western Great Lakes region of North America. My objective was to provide a more comprehensive picture of spring plant-pollinator interactions by examining the pollen carried by bees during their daily foraging activities. I selected seven sites in eastern Wisconsin based on the presence of relatively rich spring ephemeral wildflower populations. During spring 2021 and 2022, field assistants and I collected 503 total bees for pollen load analysis across all sites. Pollen loads were analyzed with light microscopy to identify plant species and the proportion of each species present in pollen loads. Reference slides of pollen grain were created to simplify the identification process. Spring bees in Wisconsin are generalists, including several species previously described as specialized on one species or several closely related plant species. Virtually all bee species examined in this study carried pollen from a variety of plants, most likely driven by floral availability, although herbaceous wildflowers were much more strongly represented than woody species. Claytonia, Cardamine, Erythronium, and Sanguinaria were all found in the majority bee species' pollen loads. Claytonia and Cardamine were the most abundant pollen grains found in bee pollen loads. The availability of early spring wildflowers clearly is important for supporting a diversity of spring bee species. Results suggest that natural area management in this region should focus on continued control and removal of invasive plant species, which can outcompete early spring plants and threaten resource diversity.

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 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.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to increase knowledge of bee species presence and abundance in some of the under-sampled areas of Wisconsin. I conducted baseline surveys in State Natural Areas in Langlade, Lincoln, Taylor, Jackson, Vernon, and Grant counties. Using protocols from the Bumble Bee Brigade and Lebuhn et al. (2003), I employed visual/photography surveys, bowl trapping, and netting to help collect data to better understand what bee species are present in these counties. Results provide a significantly clearer picture of bee assemblages in these areas of Wisconsin. I documented a total of 85 native bee species from 6 different families during surveys conducted in 2020. Eleven different bumble bee species, including three State Special Concern species were also recorded. The overall most common species found throughout all survey sites was Bombus ternarius with a total of 83 records across 20 sites.

This book was released on 2012 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bees recruit foragers to rich food sources through the waggle dance. The waggle dance has been used extensively to study the foraging ecology of honey bees in various habitats. We decoded waggle dances and used DNA barcoding of bee-collected pollen to characterize the foraging ecology of honey bees Apis mellifera L.) over 17 months around La Jolla, California, a heavily fragmented environment containing urban, semi-urban, and patches of native scrub habitats. We divided the year into three distinct seasons (dormant, growth, and dry) based on natural patterns of warming and rainfall to understand how honey bee foraging varies over ecologically relevant temporal scales in a fragmented environment. We detected a significant effect of season on foraging distances. We also found that colonies focused their foraging efforts on few patches during the dormant season and performed increasingly wider searches for pollen with changes in season. Lastly, we detected significant seasonal turnover in the proportion of pollen loads with native or non-native pollen. Bees focused their pollen foraging on native species during the dormant season; both native and non-native species during the growth season; and, non-native species during the dry season. Our results show that honey bees are capable of adjusting their foraging behavior with season to exploit common, abundant native and non-native flowers, illustrating the remarkable adaptability of honey bees in fragmented habitats. Furthermore, our study indicates that honey bees may serve as pollinators of common native plants in light of declines in native pollinators bought on by habitat fragmentation.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.
