Available in PDF, EPUB and Kindle. Book excerpt: Bee Genetics and Breeding provides an overview of the state of knowledge in bee genetics and breeding. The book is organized into two parts. Part I deals with the scholarly issues of bee genetics. It is intended as a reference source for students of both bees and genetics. It could also serve as a text for university courses in bee genetics. Topics discussed include the evolution of eusocial insects; geographical variability and classification of honey bees; and behavioral and biochemical genetics of honey bees. Part II deals more specifically with the practical issues of bee breeding. The discussions include the quantitative genetics of honey bees; ways to define and measure honey-bee characteristics so that the "best" parents for honey-bee stock improvement programs can be selected; and mating designs. This section contains sufficient guidance for bee breeders to initiate or improve breeding programs. Apiculturalists generally will find this part especially interesting since the quality of their own bee stock depends on the skills and knowledge of the breeders who produce their queens.

Available in PDF, EPUB and Kindle. Book excerpt: "It is not an exaggeration to say that the honey bee is the most well understood insect. We know more about Drosophila genetics, but our integrative understanding of that species pales in comparison to our understanding of every facet of honey bee biology. Despite the tremendous growth in our understanding of honey bee biology, the last comprehensive book on topic was published in 1987. In this book, Brian Johnson offers a comprehensive and up-to-date treatment of honey bee biology. The book covers classic topics such as physiology, communication, division of labor, and reproduction as well as areas that were barely known decades ago such as genomics, cognition, toxicology, and immunity. He concludes with a discussion of honey bees as managed pollinators and conservation issues. Throughout, Johnson also offers his analysis and evaluation of key studies and areas of research. Ultimately, this book is likely to be the new standard reference on honey bee biology and an invaluable resource for anyone with a serious interest in these fascinating organisms"--

Available in PDF, EPUB and Kindle. Book excerpt: There is no doubt that selection acts at the individual level but, there is heated debate over the relative importance of higher and lower levels of selection. Kin selection is the dominant paradigm explaining the evolution of cooperation. Whereby, individually detrimental traits can be selectively favored if they increase the fitness of genetic relatives. Kin selection operates at the individual level, biasing cooperation towards those sharing the most genes. However, kin selection may also act at the group level when efficiently functioning groups are more productive than dysfunctional ones, provided group success correlates to kin structure. Finally, kin selection can occur at the genome level within individuals, where paternally and maternally-inherited genes may favor different behaviors and actions. The imprinting of genes to parent-of-origin could also have important ramifications for social evolution. Here, I exploit the conflict over male production in honey bees to examine how these three levels of selection operate. Honey bee workers could 'police' eggs laid by other workers either to maintain colony-level productivity, favor more closely related individuals or as a result of intragenomic conflict (i.e. the paternal genome favors laying, the maternal one favors policing). Firstly, I found that although African workers lay eggs more rapidly than European workers, there is no difference in their times to ovary activation. Significant effects of both the juvenile and adult social environment on ovary activation, suggest that environment has a larger effect on the propensity to activate ovaries rather than subspecies. Secondly, I mathematically simulated a typical eusocial colony where I varied the number of mates per queen, viability of worker-laid males, colony efficiency costs of reduced worker helping, and whether or not intragenomic conflict could be expressed. Genome level selection dominated over both individual and group levels, and group level selection was more significant than the individual level in determining when queens dominate male production. Thirdly, individual level selection predicts policing late into larval development whilst benefits accrued through colony efficiency predicts workers should stop policing viable larvae soon after hatching. To this end I reared queen and worker laid male larvae in a queenless colony and transferred male larvae, from both sources, of differing ages, into a queenright colony. Post transferal (4 and 24 h), I found that workers equally removed larvae regardless of age or maternal source. With the observed high efficiency of policing eggs, these results suggest no mechanism has evolved to police larvae. Alternatively, drones may have a higher level acceptance threshold than female larvae, due to the possibility that they are laid by workers. Finally, I examined genome level selection by crossing African and European honey bees and then placing the emerging worker offspring into a queenless colony. I observed behavior from day 8 to 28 and collected marked workers on day 16 and 28. I predicted that parent-of-origin effects would occur, but instead found workers of both crosses have higher levels of ovarial development than their purebred counterparts. This suggests an imprinting mismatch such that only the paternal imprint is expressed. Together these results indicate that selection is acting at levels besides that of the individual. Continued research is needed to understand how selection, interacting over multiple levels, impacts behavior, across the animal kingdom.

This book was released on 2009 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Western Honeybee (Apis mellifera) displays a special form of social behavior called eusociality. The evolution of its reproductively specialized castes and social behavior from a solitary ancestor may be explained by the reproductive ground plan hypothesis. This hypothesis predicts a relationship between the variation of ovary size and -activity and social behavior. At the phenotypic level, ovary size has been associated with a whole set of behavioral phenotypes, known as the pollen hoarding syndrome. While many of these phenotypes are potentially influenced by regulatory pathways, involving juvenile hormone and vitellogenin, the exact genetic links between ovary size determination and social behavior are still unknown. To test the generality of the hypothesized genetic linkage between reproductive and social behavior, I investigated the genetic architecture of ovary size differences between Africanized and European honey bees. Two backcrosses of a hybrid queen and Africanized drones that resulted in transgressive worker ovary phenotypes were studied for pleiotropic effects of existing behavioral QTL and potential new QTL with a combination of SNP and microsatellite markers. Analyses show small but significant effects on ovary size for some of the behavioral QTL, as predicted by the reproductive ground plan hypothesis. In addition, I detected two new QTL of major effect on ovary size. I describe potential candidate genes for the QTL and suggest that the detected major and minor effects could reflect genetic control of caste divergence and worker division of labor, respectively, representing two distinct stages of honey bee social evolution that may be connected via female reproductive physiology."--Abstract from author supplied metadata.
Download or read book The Lives of Bees written by Thomas D. Seeley and published by Princeton University Press. This book was released on 2019-05-28 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeley, a world authority on honey bees, sheds light on why wild honey bees are still thriving while those living in managed colonies are in crisis. Drawing on the latest science as well as insights from his own pioneering fieldwork, he describes in extraordinary detail how honey bees live in nature and shows how this differs significantly from their lives under the management of beekeepers. Seeley presents an entirely new approach to beekeeping--Darwinian Beekeeping--which enables honey bees to use the toolkit of survival skills their species has acquired over the past thirty million years, and to evolve solutions to the new challenges they face today. He shows beekeepers how to use the principles of natural selection to guide their practices, and he offers a new vision of how beekeeping can better align with the natural habits of honey bees.

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.
Download or read book Regulation of Worker Reproduction in the Honey Bee Apis Mellifera L written by Shelley Hoover and published by . This book was released on 2005 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive division of labour is a defining characteristic of eusocial insects. In honey bees, there is normally a single, highly fecund queen, responsible for producing all the brood in the colony. Workers are functionally sterile, developing their latent ovaries only upon queen loss. Workers cannot mate, and are only capable of laying unfertilised, male eggs. I investigated the effects of various chemical, genetic, and nutritional factors on the ovary development of honey bee workers. I demonstrate that queen mandibular pheromone inhibits worker ovary development in caged queenless workers to the same degree as queen extracts. Four newly identified queen pheromone components did not inhibit ovary development alone, nor did they increase the efficacy of the other components. Anarchistic bees are a line developed by recurrent selection in which workers commonly reproduce in queenright colonies. There was no difference between the ovary development of anarchistic or wild type workers in colonies headed by anarchistic or wild type queens, therefore queen type is not responsible for the phenomenon. Anarchistic workers perceive queen pheromones, and anarchistic queens produce an attractive blend, as I found no differences in the retinue response of either worker type to either queen type. There also was no difference in response to queen pheromones at a high dose. At lower doses, however, wild type workers were more inhibited by queen pheromones than were anarchistic workers. Both adult and larval diet influenced adult ovary development, but workers fed high quality diets as adults had higher levels of ovary development than those fed low quality diets as adults regardless of larval diet quality. Nutrition is likely responsible for the seasonal variation observed in ovary development. Disruptive selection resulted in lines of bees with high or low levels of ovary development. High ovary development colonies collected far more pollen than their low line counterparts. Cross-fostering workers from the high line into the low line and vice versa demonstrated that there is an effect of both genotype and rearing environment. These results demonstrate the complex interactions between nutrition, pheromones, genetics, and environment that determine worker reproductive potential.
