Book excerpt: Seminar paper from the year 2012 in the subject Biology - Zoology, grade: A, ( Atlantic International University ) (School of Science and Engineering), course: Master of Science (Applied Entomology), language: English, abstract: Bees evolved in specific areas of the world long ago, before they spread to become globally as they are today (Tables 1 and II), according to Kugonza (2009). As they spread, they became adapted to the local ecological conditions of the different areas, changing in morphology and behaviour to fit within the requirements of the ecosystem, giving rise to a wide bee biodiversity of bee species and races we see today. Bees are classified under Animal Kingdom, Phylum Arthropoda. They belong to Class Insecta, which is divided into 29 Orders. Bees belong to the order Hymenoptera, which has three Super families, namely: Apoidea (bees), Formicoidea (ants) and Vespoidea (wasps). There are around 30,000 named species of bees (Apoidea). Apoidea is further divided into several Families, namely Apidae (social bees), colletidae, Andrenidae, Halictidae, Melittidae, Megachilidae, and Anthophoridae. Most of the Families have solitary individuals: each female bee makes her own nest, lays a single egg and provides food for the single larva that develops. However, a high level of social development is shown by the species in Apidae where the individuals live together in a permanent, large colony, headed by a single egg-laying queen (BfD, 2003c). Apidae is composed of four genera: Apis (honeybees), Trigona and Melipona (stingless bees), and Bombus (bumble bees). According to MAAIF (2012a), the genus Apis is comprised of 5 main species of honey bees: Apis dorsata (the giant honey bee); Apis laboriosa (the darker giant honey bee); Apis florea (the little or dwarf honey bee); Apis cerana (formerly Apis indica), is the eastern hive honey bee; and Apis mellifera (western honey bee). These species have evolved and differentiated into more species and races of honey bees. Kugonza (2009) described 9 species of honey bees in the world, which Oldroyd and Wongsiri (2006) grouped under 3 subgenera: Micrapis (Apis florea and A. andreniformis), Megapis (A. dorsata and A. laboriosa) and Apis (A. cerana, recently recognized as separate races of A. nigrocinta, A. koschevnikovi and A. nuluensis, and A. mellifera). Dietz (1992), Hussein (2000) and Wikipedia (2012) described over 28 races of A. mellifera alone. Beekeeping started with honey bees (Apis species), a practice called Apiculture, although keeping of stingless bees, belonging to the genera Trigona and Melipona, a practice called Meliponiculture, has recently picked up [...]
Download or read book Comparative and Experimental Studies on the Foraging and Exploratory Behavior of Four Honey Bee Species written by Allison Mitchell Young and published by . This book was released on 2021 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary challenges foraging animals face is deciding how to divide their time between exploitation of known resources and exploration for new resources. As foraging is costly, investment in exploration should be mediated by natural selection to balance its costs and benefits in ways are tuned to species life history (e.g., lifespan, reproduction rate, activity level), individual state (e.g., experience, hunger, cognitive abilities), and environmental conditions (e.g., reward predictability, distribution, abundance). Efforts to understand the role each factor plays in the exploitation-exploration tradeoff are complicated by the complex scenario-specific ways in which they interact. In addition, the lack of comparative information on exploratory behavior limits our ability to draw generalizations. In this dissertation, I use a combination of experiments and comparative studies in four honey bee species to examine how interactions between life history, individual experience, and environmental conditions shape investment in foraging and exploration. Each chapter addresses how the interaction between two factors (e.g., life history and environment, individual experience and environment) shapes honey bee exploration, or provides an in-depth look at a previously understudied aspect of Asian honey bee life history and foraging behavior that could play a role in shaping their exploratory behavior. In Chapter 1, I investigate how evolved differences in life history interact with environmental reward context to shape worker investment in exploration in four honey bee species. Species that face higher mortality costs from exploration were generally less exploratory when confronted by a decrease in a familiar reward, but all species increased their investment in exploration as they experienced larger decreases in resource quality. These findings suggest that exploratory behavior has been tuned by natural selection to species life history but is also sensitive to the current environmental conditions. In Chapter 2, I use Apis mellifera to investigate how different past experiences with environmental predictability in the location or timing of rewards influence how honey bees search when those rewards are no longer available. My results show that honey bees that have had experience with unpredictable rewards are less precise but equally persistent in their search for vanished rewards, as compared with bees that have had experience with predictable rewards. This result suggests that a bee's experience with resource predictability shapes the way she searches but not her overall investment in exploration. In Chapter 3, I investigate the lifespan and foraging behavior of three honey bee species. For all three species, the age at which a bee first becomes active outside the nest was the primary predictor of her lifespan. Dwarf honey bee (A. florea) workers seem to have the longest lifespan, likely due to their much-delayed onset of flight outside the hive, supporting the idea that species that face higher costs from worker mortality should have longer-lived workers. Finally, in Chapter 4, I examine how investment in diurnal and nocturnal foraging activity by the giant honey bee (A. dorsata) changes across seasons and lunar cycles. I found that this species could be considered both diurnal and crepuscular, as well as facultatively nocturnal. The amount of nocturnal activity performed depended greatly on environmental illumination and the season, whereas crepuscular activity was extremely high regardless of season or illumination. This study paves the way for further investigations into the mortality costs associated with nocturnal foraging, and how those costs might shape their exploratory behavior during the day.

Download or read book The Pollen Foraging Ecology of Honey Bees Apis Mellifera in a Fragmented Environment written by Byeong Hon Park and published by . 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 Honey Bee Landscape Ecology written by Douglas B. Sponsler and published by . This book was released on 2016 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 5 applies the modeling principles presented in Chapter 4 to the issue of honey bee exposure to neonicotinoid insecticides during the planting of seed-treated corn. During planting, the neonicotinoid-laden seed treatment material is shed from the seed surface and dispersed in the environment in small particles. This inadvertent release of insecticide has been implicated in honey bee mortality incidents throughout Europe and North America, but the precise route of exposure linking honey bees to the neonicotinoids has remained obscure. I approach the issue from a landscape perspective, using two years of field data on honey bee exposure and mortality during corn planting in central Ohio. By constructing overlapping models of environmental contamination and honey bee foraging, I estimate the degree of exposure potential associated with different components of the landscape, and then use these estimates to test the predictions of several hypothesized routes of exposure. My results indicate that the primary route of exposure is the contamination of bee-attractive flora within corn fields at the time of planting, implying that exposure could be mitigated effectively by the destruction of in-field weeds prior to planting. Chapter 6 tests and extends the findings of Chapter 5 using a simulation model of honey bee exposure to corn seed treatment neonicotinoids. The patterns of exposure generated by this model support the conclusions of Chapter 6 while indicating that the preservation or augmentation of flowering weeds in soybean fields may be equally important in suppressing honey bee exposure.
Download or read book Asian Honey Bees written by Benjamin P. Oldroyd and published by Harvard University Press. This book was released on 2009-06-01 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The familiar European hive bee, Apis mellifera, has long dominated honey bee research. But in the last 15 years, teams in China, Japan, Malaysia, and Thailand began to shift focus to the indigenous Asian honey bees. Benjamin Oldroyd, well known for his work on the genetics and evolution of worker sterility, has teamed with Siriwat Wongsiri, a pioneer of the study of bees in Thailand, to provide a comparative work synthesizing the rapidly expanding Asian honey bee literature. After introducing the species, the authors review evolution and speciation, division of labor, communication, and nest defense. They underscore the pressures colonies face from pathogens, parasites, and predators--including man--and detail the long and amazing history of the honey hunt. This book provides a cornerstone for future investigations on these species, insights into the evolution across species, and a direction for conservation efforts to protect these keystone species of Asia's tropical forests.

This book was released on 2020-06-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most flowering plants, including wild species and many food crops, are pollinated by animals and are vital, therefore, for biological production and the maintenance of biodiversity. Pollinators benefit from diverse natural habitats for forage and nesting, especially when these are limited in plant production systems. Landscape and forest management practices can help ensure the continued availability of pollinators and thereby increase resilience and the productivity of forestry and agriculture. The extent of forests and other natural habitats in a landscape plays a role in determining the species composition of pollinators. Agricultural landscapes adjoining fragmented forests and natural areas benefit from pollinator services, and animal-pollinated crops therefore achieve higher fruit set. Forest management practices can have significant effects on pollinator abundance and diversity. They affect forest variables such as structure, species composition, soil dynamics, hydrology and light availability, all of which can affect pollinator species composition and diversity and plant–pollinator networks. Indigenous and local knowledge can contribute to the conservation of pollinators through traditional management practices. This working paper, which is aimed at forest practitioners, landscape planners and land-use decision-makers, reviews published literature on the impacts of forest and landscape management practices on pollinators. It also addresses the implications of climate change, collates 36 case studies, and makes recommendation on measures for maintaining pollinator diversity and abundance in forests and landscapes

Download or read book Bee Conservation written by Lynn V. Dicks and published by Pelagic Publishing. This book was released on 2010-01-01 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together scientific evidence and experience relevant to the practical conservation of wild bees. The authors worked with an international group of bee experts and conservationists to develop a global list of interventions that could benefit wild bees. They range from protecting natural habitat to controlling disease in commercial bumblebee colonies. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bees quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bee conservation actions throughout the world. Bee Conservation is the first in a series of synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)’s Unified Classification of Direct Threats.
Download or read book Stingless Bees written by Christoph Grüter and published by Springer Nature. This book was released on 2020-12-03 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stingless bees (Meliponini) are the largest and most diverse group of social bees, yet their largely tropical distribution means that they are less studied than their relatives, the bumble bees and honey bees. Stingless bees produce honey and collect pollen from tens of thousands of tropical plant species and, in the process, provide critical pollination services in the tropics. Like many other insects, they are struggling with new human-made challenges like habitat destruction, climate change and new diseases. This book provides an overview of stingless bee biology, with chapters on the evolutionary history, nesting biology, colony organisation and division of labour of stingless bees. In addition, it explores their defence strategies, foraging ecology, and varied communication methods. Accordingly, the book offers an accessible introduction and reference guide for students, researchers and laypeople interested in the biology of bees.
