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.

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 Foraging Behavior of the Honey Bee Apis mellifera L written by John Purdy and published by Elsevier. This book was released on 2023-10-27 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Foraging Behavior of the Honeybee (Apis mellifera, L.) provides a scholarly resource for knowledge on the regulation, communication, resource allocation, learning and characteristics of honeybee foraging behavior at the individual and colony level. Foraging, in this context, is the exploration of the environment around a honey bee hive and the collection of resources (pollen, nectar, water, etc.) by bees in the worker caste of a colony. Honeybees have the unique ability to balance conflicting and changing resource needs in rapidly changing environments, thus their characterization as “superorganisms made up of individuals who act in the interest of the whole. This book explores the fascinating world of honey bees in their struggle to obtain food and resources in the ecosystem and environment around the hive. Written by a team of international experts on honey bee behavior and ecology, this book covers current and historical knowledge, research methods and modeling used in the field of study and includes estimates of key parameters of energy utilization, quantities of materials collected, and identifies inconsistencies or gaps in current knowledge in the field. Establishes a basis of current knowledge on honeybees to build and advance understanding of their foraging behavior Addresses stressors such as habitat loss, climate change, pesticides, pests and diseases Presents concise concepts that facilitate direct traceability to the original underlying research

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 Neurobiology of Chemical Communication written by Carla Mucignat-Caretta and published by CRC Press. This book was released on 2014-02-14 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Available in PDF, EPUB and Kindle. Book excerpt: While numerous factors currently impact the health of honey bees and other pollinating Hymenoptera, poor floral resource availability due to habitat loss and land conversion is thought to be important. This issue is particularly salient in the upper Midwest, a location which harbors approximately 60 percent of the US honey bee colonies each summer for honey production. This region has experienced a dramatic expansion in the area devoted to crop production over the past decade. Consequently, understanding how changes to landscape composition affect the diversity, quality and quantity of available floral resources has become an important research goal. Here, I developed molecular methods for the identification of bee-collected pollen by adapting and improving upon the existing amplicon sequencing infrastructure used for microbial community ecology. In thoroughly benchmarking our procedures, I show that a simple and cost-effective three-step PCR-based library preparation protocol in combination with Metaxa2-based hierarchical classification yields an accurate and highly quantitative pollen metabarcoding approach when applied across multiple plant markers.
Download or read book Comparative Social Evolution written by Dustin R. Rubenstein and published by Cambridge University Press. This book was released on 2017-03-24 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.

Download or read book The Routledge International Handbook of Comparative Psychology written by Todd M. Freeberg and published by Taylor & Francis. This book was released on 2022-08-31 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Routledge International Handbook of Comparative Psychology is an international reference work that offers scientists and students a balanced overview of current research in the field of comparative psychology and animal behavior. The book takes an integrative approach to animal behavior, with most of the chapters discussing research involving both proximate (developmental and mechanistic) and ultimate (functional and phylogenetic) levels of analysis. Chapters cover the major ideas of core topics in the field and examine emerging research trends to provide readers deeper understanding of these ideas. One of the strengths of this book is its the coverage of core topics in comparative psychology and animal behavior from different – and diverse – perspectives. The diverse perspectives come from the wide range of focal species studied by chapter authors, a range traditionally quite atypical for comparative psychology, and from the widespread international representation of the authors and the diversity of departments and research centers at which these authors work in. The first part of the Handbook examines historical and foundational principles and theories in the field. The second part focuses on individual behavior systems. The final part of the book is devoted to a diversity of ideas that extend our understanding of behavior into new directions. The Routledge International Handbook of Comparative Psychology is an essential resource for advanced undergraduate and graduate students, postdoctoral researchers, and established academics, as well as others who are interested in comparative psychology and animal behavior.
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.
