Bee photo by Zachary Huang Honey bee genetics Genetics is the study of variable traits of organisms and how they are transmitted from one generation to the next.

Genes are units of DNA that act as a blueprint for these traits. Even though humans first started keeping honey bees at least years ago, it was not until the mids that people started to understand honey bee reproduction and. We show that Firm5 strains isolated from honey bees and bumble bees separate into deep-branching host-specific phylogenetic lineages.

Despite their divergent evolution, colonization experiments show that bumble bee strains are capable of colonizing the honey bee gut. The Bumblebee Book offers an easy introduction for those new to bumblebees and also provides the more experienced naturalist with a wealth of information about their fascinating lives.

All 27 bumblebee species occurring in Britain and Ireland are illustrated by photographs showing their full range of variation, including the striking island races.

Corbiculate bees include the highly eusocial honey bees and stingless bees, the primitively eusocial bumble bees, and the predominantly solitary or communal orchid bees.

Here we use a model-based approach to reconstruct the evolutionary history of eusociality and date the antiquity of eusocial behavior in apid bees, using a recent molecular. INTRODUCTION. Bees, ranging from wild solitary species to highly social and managed species like honey bees, play key roles in natural and agricultural ecosystems worldwide (1,– 3).Recent losses of honey bees and wild bees have been attributed to pesticide exposure, poor nutrition, increased parasite loads, habitat degradation, and reduced genetic diversity (4, 5).

Biology is the study of life. How our understanding of the nature and evolution of living systems is being enriched and extended through new discoveries about social learning and culture in human and nonhuman animals is the subject of the collection of articles we introduce here.

Recent decades have revealed that social learning and the transmission of cultural traditions are much more. Whether you are giving gifts to others or to yourself, this list of the best popular science books of about evolution, genetics and natural history is a great place to start reading and gifting.

Our lab team performs research on the ecology, evolution, genetics, and behavior of bees, with a special focus on bumble bees. Projects in the lab are integrative and cover numerous facets of science, with recent undergraduates pursuing projects spanning topics such as molecular genetics, field ecology, behavior, chemical ecology, geography, thermal biology, pigment research, and toxicology.

Here, we review and synthesize new insights into the ecology, evolution and behaviour of bumble bees that have been gained using modern genetic and genomic techniques.

Special emphasis is placed on four areas of bumble bee biology: the evolution of eusociality in this group, population-level processes, large-scale evolutionary relationships and.

The fact that the bee fossil also has some wasp traits suggests an evolutionary link between wasps and bees. In a related study, published in the Oct. 10 issue of the Proceedings of the National.

Gut microbes are increasingly recognized as influential components of animal biology. Genomic, mechanistic, and evolutionary aspects of gut symbiont specialization remain understudied, however, largely due to the complexity of gut communities, especially in vertebrate systems. We show that the simple microbiota of eusocial bees exhibits host specificity and that coresident species in the.

The analyses revealed a “clear pattern of increased potential for gene regulation” in both evolutionary branches of eusocial bees, Kapheim told The Scientist. For example, there was an increase in the number of genes predicted to be methylated (a form of epigenetic regulation) and an increase in the number of transcription factor binding.

Department of Ecology and Evolutionary Biology, Yale University,New Haven, CT,USA. Int J Syst Evol Microbiol Pubmed # ABSTRACT: Honey bees and bumble bees harbour a small, defined set of gut bacterial associates. Strains matching sequences from 16S rRNA gene surveys of bee gut microbiotas were isolated from two honey bee.

The taxonomic status of closely related bumble bee species is often unclear. The relationship between the two nominate taxa, Bombus melanopygus Nylander (Hymenoptera: Apidae) and Bombus edwardsii Cresson (Hymenoptera: Apidae), was investigated using genetic (enzyme electrophoretic) and morphometric analyses.

The taxa differ in the color of the abdominal terga two and three, being. 2. Insect societies. Social insects, and bees in particular, provide an excellent model system with which to study the evolution of sociality because there is a broad range of taxonomically related species that encompass all levels of sociality, from species with essentially solitary lives all the way to eusocial species with colonies of thousands of highly specialized individuals (figure 1).

A long-standing controversy in bee social evolution concerns whether highly eusocial behavior has evolved once or twice within the corbiculate Apidae. Corbiculate bees include the highly eusocial honey bees and stingless bees, the primitively eusocial bumble bees, and the predominantly solitary or communal orchid bees.

Here we use a model-based approach to reconstruct the evolutionary. Climate oscillations have left a significant impact on the patterns of genetic diversity observed in numerous taxa.

In this study, we examine the effect of Quaternary climate instability on population genetic variability of a bumble bee pollinator species, Bombus huntii in western North America. Pleistocene and contemporary B. huntii habitat suitability (HS) was estimated with an environmental.

Bumblebees and other eusocial bees offer a unique opportunity to analyze the evolution of body size differences between sexes. The workers, being sterile females, are not subject to selection for reproductive function and thus provide a natural control for parsing the effects of selection on reproductive function (i.e., sexual and fecundity selection) from other natural selection.

The study by Florian Schiestl and Daniel Gervasi focuses on the role insect pollinators can play in plant evolution, and how speedy that evolution can be.

Image credit: Alexas. 1 day ago  Pollinator decline affects food security, and pollinators are threatened by stressors including pathogens and insufficient food resources.

Flowering strips are increasingly planted to increase pollinator abundance and diversity in agricultural settings, but flowers can also be disease transmission sites between pollinators. However, the effect of plant species composition on bee disease is.

But artificial nest boxes—or bumble bee “domiciles”—just might make studying the nesting ecology of these wild bees easier. For instance, ornithologists know much more about the nesting biology of bluebirds than meadowlarks because the former can be convinced to nest in convenient, easy-to-access nest boxes, while the latter constructs well-hidden nests on the ground in grasslands.

Bumble bee queens and workers have the same genome but different lifespans, similar but not as pronounced as the difference between queen and worker honey bees.

Bumble bees share some pests and pathogens with honey bees, and have been used to describe several key elements of insect immunity, tolerance, and resistance to pathogens and parasites.

studying the evolution and ecology of the bumble bees of the intermountain west. of bumble bee biology. He focuses on the conservation of declining bumble bee species as well as the domestication and breeding of bumble bees for commercial pollination.

His current research interests include bumble bee hibernation and the genetic diversity of. A new study led by researchers at Penn State has identified the gene responsible for the color switch between the red and black color forms of the bumble bee, Bombus melanopygus.

The black form is similar to other bees in the Pacific Coastal region while the red form is similar to other bees in the Rocky Mountain region. When it comes to honey bees, more mates is better. A new study shows that genetic diversity is key to survival in honey bee colonies -- meaning a colony is less likely to survive if.

Page is known for his research on honey bee behavior and population genetics, particularly the evolution of complex social behavior. One of his most salient contributions to science was to construct the first genomic map of the honey bee, which sparked a variety of pioneering contributions not only to insect biology but to genetics at large.

G eneticist Dr. Kat Arney brings you exclusive excerpts from her new book, Rebel Cell: Cancer, evolution and the science of life, exploring where cancer came from. The commercial production of bumble bee colonies is a multi-million dollar business worldwide.

The pollination of greenhouse tomatoes is largely dependent on this industry. However, microparasites are prevalent in many of these colonies and can spread to wild populations of bumble bees. Academic researchers now commonly purchase colonies for their work.

Each year in the UK, commercial tomato growers use an estimated 2 million bumble bees to pollinate their crops. The economic value of bumble bees and honey bees as pollinators in the UK is estimated at over £ million.

Other crops that rely on bees for pollination are also used in animal feeds and are necessary for rearing livestock.
