RESUMO

During the English Civil War and subsequent Restoration, beekeeping provided a ready set of moral examples for those seeking answers about the 'natural' structure of society. The practice itself also underwent a number of substantial changes, moving from a traditional craft practice to a more knowledge-focused, technologically complex one. The advent of glass-windowed hives in the latter half of the sixteenth century allowed intellectuals from across the political spectrum to directly observe bees as a way of gathering knowledge about how to understand the divine plan and, with that understanding, improve human society.

RESUMO

Historical specimens in museum collections provide opportunities to gain insights into the genomic past. For the Western honey bee, Apis mellifera L., this is particularly important because its populations are currently under threat worldwide and have experienced many changes in management and environment over the last century. Using Swiss Apis mellifera mellifera as a case study, our research provides important insights into the genetic diversity of native honey bees prior to the industrial-scale introductions and trade of non-native stocks during the 20th century-the onset of intensive commercial breeding and the decline of wild honey bees following the arrival of Varroa destructor. We sequenced whole-genomes of 22 honey bees from the Natural History Museum in Bern collected in Switzerland, including the oldest A. mellifera sample ever sequenced. We identify both, a historic and a recent migrant, natural or human-mediated, which corroborates with the population history of honey bees in Switzerland. Contrary to what we expected, we find no evidence for a significant genetic bottleneck in Swiss honey bees, and find that genetic diversity is not only maintained, but even slightly increased, most probably due to modern apicultural practices. Finally, we identify signals of selection between historic and modern honey bee populations associated with genes enriched in functions linked to xenobiotics, suggesting a possible selective pressure from the increasing use and diversity of chemicals used in agriculture and apiculture over the last century.

RESUMO

Beekeeping had its origins in honey hunting-the opportunistic stealing of honey from wild honey bee nests. True beekeeping began when humans started providing artificial cavities within which the bees could build comb for the queen to lay her eggs and the workers could process honey. By 2450 BCE, the Egyptians had developed sophisticated apiculture, and, within two millennia, beekeeping with horizontal hives had spread throughout the Mediterranean. During Europe's Middle Ages, honey and wax became important commodities for trade, and beekeeping in skep, log, box, and tree hives flourished to meet the demand. Other species of honey bees contributed to the development and spread of beekeeping in Asia beginning around 300 BCE. Meanwhile, beekeeping evolved independently in Mesoamerica with the stingless bee Melipona beecheii, as documented by archaeological finds and written accounts that survived Spanish conquest.

RESUMO

The pressures on honeybee (Apis mellifera) populations, resulting from threats by modern pesticides, parasites, predators and diseases, have raised awareness of the economic importance and critical role this insect plays in agricultural societies across the globe. However, the association of humans with A. mellifera predates post-industrial-revolution agriculture, as evidenced by the widespread presence of ancient Egyptian bee iconography dating to the Old Kingdom (approximately 2400 BC). There are also indications of Stone Age people harvesting bee products; for example, honey hunting is interpreted from rock art in a prehistoric Holocene context and a beeswax find in a pre-agriculturalist site. However, when and where the regular association of A. mellifera with agriculturalists emerged is unknown. One of the major products of A. mellifera is beeswax, which is composed of a complex suite of lipids including n-alkanes, n-alkanoic acids and fatty acyl wax esters. The composition is highly constant as it is determined genetically through the insect's biochemistry. Thus, the chemical 'fingerprint' of beeswax provides a reliable basis for detecting this commodity in organic residues preserved at archaeological sites, which we now use to trace the exploitation by humans of A. mellifera temporally and spatially. Here we present secure identifications of beeswax in lipid residues preserved in pottery vessels of Neolithic Old World farmers. The geographical range of bee product exploitation is traced in Neolithic Europe, the Near East and North Africa, providing the palaeoecological range of honeybees during prehistory. Temporally, we demonstrate that bee products were exploited continuously, and probably extensively in some regions, at least from the seventh millennium cal BC, likely fulfilling a variety of technological and cultural functions. The close association of A. mellifera with Neolithic farming communities dates to the early onset of agriculture and may provide evidence for the beginnings of a domestication process.

RESUMO

Ahmed Zaky Abushady, (1892-1955) was an author, beekeeper, doctor and poet. This paper follows his life from his upbringing in Egypt and his time as a medical student in England to his later life as a pathologist working in Alexandria and Cairo and finally his years in the United States of America. It emphasises his contributions in several fields not directly related to medicine and looks at his continuing influence.
