Francis L.W. Ratnieks (born 1953) is a British entomologist and emeritus professor of apiculture at the University of Sussex in the United Kingdom. [1] He is known for his research in the field of social insects, particularly in the behavior, ecology, and evolution of honey bees.
Ratnieks was born to a Latvian father and English mother in Reading, and later enrolled in a Biology undergraduate degree at the University of Sussex, but dropped out after a year and spent time on fishing boats, making jewellery and working as a licensed pedlar. [2] After 8 years in Northern Ireland, he was accepted on a BSc course at the University of Ulster in Ecology. Ratnieks subsequently undertook MS and PhD degrees at Cornell University on honey bee biology, supervised by Professor Roger A. Morse and Thomas D. Seeley.
After obtaining MS and PhD degrees, Ratnieks worked with the New York State Apiary Inspection Program and was hired as a postdoctoral researcher at University of California, Berkeley and at Riverside, as well as teaching at Aarhus University, Denmark. In 1995, Ratnieks set up the Laboratory of Apiculture and Social Insects (LASI) at the University of Sheffield as the UK's first and only Professor of Apiculture. Ratnieks then moved LASI to the University of Sussex [3] after being hired by Professor Jonathan Bacon, where much research has been carried out on the honeybee waggle dance and its calibration, the treatment and pathogenicity of honey bee diseases, and the decision making capabilities of ants. Under Ratnieks professorship, LASI has also arranged research abroad in Brazil in collaboration with the University of São Paulo, studying stingless bees and Neotropical ant species.
As a professor he has supervised several well-known entomologists and biologists, including science communicator Adam Hart, evolutionary biologists Kevin Foster and Tom Wenseleers, and entomologists Madeleine Beekman, Christoph Grüter, Tomer Czaczkes, Stephen John Martin, Thibaud Monnin, Nigel Raine, Elva Robinson, Roger Schürch and Margaret Couvillon.
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are currently considered a clade, called Anthophila. There are over 20,000 known species of bees in seven recognized biological families. Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.
Berthold Karl HölldoblerBVO is a German zoologist, sociobiologist and evolutionary biologist who studies evolution and social organization in ants. He is the author of several books, including The Ants, for which he and his co-author, E. O. Wilson, received the Pulitzer Prize for non-fiction writing in 1991.
Myrmecology is a branch of entomology focusing on the scientific study of ants. Some early myrmecologists considered ant society as the ideal form of society and sought to find solutions to human problems by studying them. Ants continue to be a model of choice for the study of questions on the evolution of social systems because of their complex and varied forms of eusociality. Their diversity and prominence in ecosystems also has made them important components in the study of biodiversity and conservation. Recently, ant colonies are also studied and modeled for their relevance in machine learning, complex interactive networks, stochasticity of encounter and interaction networks, parallel computing, and other computing fields.
The European dark bee is a subspecies of the western honey bee, evolving in central Asia, with a proposed origin of the Tien Shan Mountains and later migrating into eastern and then northern Europe after the last ice age from 9,000BC onwards. Its original range included the southern Urals in Russia and stretched through northern Europe and down to the Pyrenees. They are one of the two members of the 'M' lineage of Apis mellifera, the other being in western China. Traditionally they were called the Black German Bee, although they are now considered endangered in Germany. However today they are more likely to be called after the geographic / political region in which they live such as the British Black Bee, the Native Irish Honey Bee, the Cornish Black Bee and the Nordic Brown Bee, even though they are all the same subspecies, with the word "native" often inserted by local beekeepers, even in places where the bee is an introduced foreign species. It was domesticated in Europe and hives were brought to North America in the colonial era in 1622 where they were referred to as the English Fly by the Native Americans.
Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new nest-site locations with other members of the colony.
Haplodiploidy is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. Haplodiploidy is sometimes called arrhenotoky.
Jeremy Field is a Professor of Evolutionary Biology at the University of Exeter. Prior to this, he was a senior lecturer in the Department of Biology at University College London between 1995 and 2007, and Professor of Evolutionary Biology at the University of Sussex from 2007 to 2016.
May Roberta Berenbaum is an American entomologist whose research focuses on the chemical interactions between herbivorous insects and their host plants, and the implications of these interactions on the organization of natural communities and the evolution of species. She is particularly interested in nectar, plant phytochemicals, honey and bees, and her research has important implications for beekeeping.
Task allocation and partitioning is the way that tasks are chosen, assigned, subdivided, and coordinated within a colony of social insects. Task allocation and partitioning gives rise to the division of labor often observed in social insect colonies, whereby individuals specialize on different tasks within the colony. Communication is closely related to the ability to allocate tasks among individuals within a group. This entry focuses exclusively on social insects. For information on human task allocation and partitioning, see division of labour, task analysis, and workflow.
The western honey bee or European honey bee is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for "bee", and mellifera is the Latin for "honey-bearing" or "honey carrying", referring to the species' production of honey.
Laurent Keller is a Swiss evolutionary biologist, myrmecologist and author. He was a professor at the University of Lausanne from 1996 to 2023. In March 2023, the journal Science reported that sexual harassment allegations were leveled against Keller. According to the Science article, the University of Lausanne sent an email to staff in February of 2023 to inform them that Laurent Keller no longer works there.
Eusociality, the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care, overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms.
Gene Ezia Robinson is an American entomologist, Director of the Carl R. Woese Institute for Genomic Biology and National Academy of Sciences member. He pioneered the application of genomics to the study of social behavior and led the effort to sequence the honey bee genome. On February 10, 2009, his research was famously featured in an episode of The Colbert Report whose eponymous host referred to the honey Dr. Robinson sent him as "pharmaceutical-grade hive jive".
Worker policing is a behavior seen in colonies of social hymenopterans whereby worker females eat or remove eggs that have been laid by other workers rather than those laid by a queen. Worker policing ensures that the offspring of the queen will predominate in the group. In certain species of bees, ants and wasps, workers or the queen may also act aggressively towards fertile workers. Worker policing has been suggested as a form of coercion to promote the evolution of altruistic behavior in eusocial insect societies.
Marla Spivak is an American entomologist, and Distinguished McKnight University Professor at the University of Minnesota specializing in apiculture and social insects.
