North American Seed-harvester Ants
■ Abstract Seed-harvester ants are a dominant and conspicuous insect group throughout arid portions of the southwestern United States and northern Mexico, and they include ∼75 species. Intense study in the late 1970s and early 1980s led to the paradigm that interspecific competition for limited seed resources is the primary factor that structures seed-harvester ant communities. This review atte...
متن کاملthe tragedy of modern man in arthur millers world
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
15 صفحه اولGenetic caste determination in Pogonomyrmex harvester ants
Division of labour between reproductive queens and sterile workers is a hallmark of insect societies and an important component of their ecological success (Hölldobler & Wilson, 1990). In ants and other social Hymenoptera forming large and complex societies, reproductive division of labour is generally associated with marked morphological differences between the queen and worker castes. These d...
متن کاملTask-specific expression of the foraging gene in harvester ants.
In social insects, groups of workers perform various tasks such as brood care and foraging. Transitions in workers from one task to another are important in the organization and ecological success of colonies. Regulation of genetic pathways can lead to plasticity in social insect task behaviour. The colony organization of advanced eusocial insects evolved independently in ants, bees, and wasps ...
متن کاملNest architecture shapes the collective behaviour of harvester ants.
Structures influence how individuals interact and, therefore, shape the collective behaviours that emerge from these interactions. Here I show that the structure of a nest influences the collective behaviour of harvester ant colonies. Using network analysis, I quantify nest architecture and find that as chamber connectivity and redundancy of connections among chambers increase, so does a colony...
