This book was released on 2011 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native bees play an important role as pollinators of natural vegetation and agricultural crops. Yet many pollinators, including some native bees, are declining in numbers. Some of the potential causes of these declines are habitat destruction and degradation by various human land uses, including urban development and sprawl, construction of roadways, and habitat conversion to agriculture such as crop production and livestock grazing. Livestock grazing is one of the most common land uses in western North America and it can impact floral and nesting resources that are important to native bees. These effects are likely manifested through grazing's effect on vegetation and soil characteristics. However, few studies have investigated how livestock grazing impacts native bees in North America. As a result, the overall goal of this research was to determine how a gradient of livestock grazing intensities impacts native bee communities in a threatened and poorly studied grassland of western North America, the Pacific Northwest Bunchgrass Prairie. Because no studies have examined the bee fauna of this grassland habitat, our study had two objectives: 1) describe the native bee community in the Zumwalt Prairie in northeastern Oregon, which is one of the largest remaining remnants of this unique grassland type, and how it changes through time, and 2) investigate how livestock grazing affects that native bee fauna. To address these objectives, we sampled pollinators during the summer of 2007 and 2008 in 16 40-ha pastures on a plateau in the Zumwalt Prairie using blue vane traps. Each pasture was assigned one of four cattle stocking rates (high, medium low, and no cattle), and grazing intensity was quantified by measuring utilization. Grazing treatments were applied in the early summer for two years. We measured soil and vegetation characteristics that related to floral and nesting resources of bees as well as several metrics of the bee community, including diversity, richness, abundance, and community composition. We found 92 species and 119 morphospecies of native bees in 27 genera. This diverse community of native bees showed strong interseasonal and interannual variation that appears to be related to weather and plant phenology. We also found that even after exposure to just two years of grazing, some effects on vegetation and soils were evident. For example, increased grazing intensity significantly reduced vegetation structure, the abundance of certain blooming plants, surface soil stability, and the amount of soil surface covered by herbaceous litter. In addition, increased grazing intensity significantly increased soil compaction and the amount of bare ground. Native bee communities responded grazing intensity through changes in abundance, richness, diversity and community composition. Different bee taxa responded to grazing intensity differently and this response varied temporally. For example, bumble bees were sensitive to grazing intensity early in the season, showing reduced abundance, diversity, and/or richness with increased grazing intensity. In contrast, halictid bees did not respond to grazing intensity in any season. However, even within a genus or family, different species responded to grazing intensity in different manners, potentially because of variation in life histories. This research suggests that maintaining land with a mixture of livestock grazing intensities may be the best way to conserve this important and diverse pollinator group in the Pacific Northwest Bunchgrass Prairie.

This book was released on 2021-09-21 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.

Available in PDF, EPUB and Kindle. Book excerpt: Habitat fragmentation due to agricultural intensification leads to losses of biodiversity and ecosystem services such as pollination. Wild bee declines pose a serious threat to pollination stability and are expected to be most severe in agricultural landscapes, providing the impetus for grassland restoration efforts like the Conservation Reserve Program (CRP) to establish pollinator habitat via forb-enhanced plantings. One form of management not applied to CRP forb-enhanced plantings is grazing. Given historical adaptation of Great Plains ecosystems to large grazers such as bison, it is possible that grazing-induced benefits to pollinators and forb communities have been overlooked. Few studies have examined the effects of restoration management on grassland native bees. Specifically, there is need to a) assess the effects of restoration plantings on native bees throughout Great Plains ecoregions, and b) examine how associated management practices, such as grazing, affect bee communities. This study is the first of its kind to assess bee and forb responses to grazing and restoration plantings across multiple ecoregions of the Great Plains. We surveyed native bee and forb communities on 108 CRP fields throughout the sand, short-, mixed-, and tall-grass prairie ecoregions of Kansas. CRP fields were either a) forbenhanced or primarily grass-planted and b) not grazed or grazed at low-intensity. Overall, we found that floral cover was the most important predictor of bee responses. Forb-enhanced restorations did not differ in floral cover or richness, but still had positive effects on native bees. Bee community responses to grazing were mostly positive with one exception: bee diversity decreased on mixed-grass, grazed fields. Additionally, bee communities responded to grazing only after grazing had ceased. Our findings provide novel insight into bee community responses to land management on restored grasslands in a predominantly agricultural Great Plains landscape.
