Messor Celiae
''Messor'' is a genus of myrmicine ants with more than 100 species, all of which are harvester ants; the generic name comes from the Roman god of crops and harvest, Messor. The subterranean colonies tend to be found in open fields and near roadsides, openings are directly to the surface. Colonies can achieve huge sizes and are notable for their intricately designed granaries in which seeds are stored in dry conditions, preventing germination. The structure of ''Messor'' spp. nests is complex and the genus on the whole is one of very accomplished architects. ''Messor'' spp. are polymorphic and have a distinct caste of macrocephalic dinoergates whose role is carrying and cutting the large seeds which comprise much of the colonies' subsistence. Although they primarily feed on seeds, they occasionally eat insects and snails. Some snail shells possibly are taken into the nest because of their grain-like shape. Equipped with a tough, shining cuticle, ''Messor'' spp. are slow-movin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste Forel
Auguste-Henri Forel (; 1 September 1848 – 27 July 1931) was a Swiss myrmecologist, neuroanatomist, psychiatrist and former eugenicist, notable for his investigations into the structure of the human brain and that of ants. He is considered a co-founder of the neuron theory. Forel is also known for his early contributions to sexology and psychology. From 1978 until 2000 Forel's image appeared on the 1000 Swiss franc banknote. Early life Born in 1848 in a villa ''La Gracieuse'', at Morges, on Lake Geneva, Switzerland, to Victor Forel a pious Swiss Calvinist and Pauline Morin, a French Huguenot he was brought up in a protective household. Auguste Forel was born in 1848 at Morges on Lake Geneva in Switzerland. His great uncle, who was an entomologist, introduced Forel to insect natural history when he was young. After reading a book by Pierre Huber, he became interested in ants. Education He went to school at Morges and Lausanne. In 1866 he began his studies at the University o ...

Messor Barbarus
''Messor barbarus'' is a species of harvester ant in the subfamily Myrmicinae. It is found In Southern Europe and Northern Africa. Interaction with Humans Messor barbarus causes 50–100% of the seed losses and is the most common ant in arable fields in northeastern Spain (Westerman et al. 2012). These ants in particular made news headlines all over Spain when farmers believed they were stealing their seeds and began a cull only to realise they actually play a massive part of the ecosystem and benefit the production for crop farmers completely. Messors will carry the seeds on their own roads back to the colony, sometimes up to 100ft away. Behavior Trail foraging behavior ''Messor barbarus'' is found to act in accordance with the optimal foraging theory, which predicts that selectivity in ants increases with increasing richness of resources in an area, as well as with increasing distance from starting location. Trails were likewise differentially favored according to the relative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
