Ecology: Tribal Warfare Maintains Microbial Diversity
نویسندگان
چکیده
When two tribes of Myxococcus bacteria attack each other, the most numerous usually wins. Established colonies can therefore resist invaders by outnumbering them. This shows how positive frequency dependence can maintain diversity across spatially structured environments.

Life histories, blood revenge, and warfare in a tribal population.
Blood revenge is one of the most commonly cited causes of violence and warfare in tribal societies, yet it is largely ignored in recent anthropological theories of primitive warfare. A theory of tribal violence is presented showing how homicide, revenge, kinship obligations, and warfare are linked and why reproductive variables must be included in explanations of tribal violence and warfare. St...

متن کاملMicrobial Ecology of Mid-Ocean Ridges and Back-Arc Basins
Over the past two decades, microbiologists have gained significant insights into the diversity and physiology of microbial communities associated with deep-sea hydrothermal systems. Much of the initial research focused on mid-ocean ridge (MOR) systems; however, because of the greater heterogeneity of vent fluid chemistry and sulfide structures from back-arc basin (BAB) systems, recent studies h...
متن کاملRediscovery of the Microbial World in Microbial Ecology
Recent progress in microbial ecology is allowing for the new discovery of the vast, poorly-characterized microbial world. The following four topics are intensively highlighted as perspectives we can use to look into the novel microbial world in nature; unexplored habitats, unexpected microbial diversity/function, microbial community including eukaryotic microbes, and complex microbial ecosystem...
متن کاملMolecular Methods in Microbial Ecology
It is now generally accepted in microbial ecology that cultivation-based approaches provide an incomplete picture of microbial diversity in the gastrointestinal (GI) tract because only a minority of microbes can be obtained in culture. Therefore, the application of molecular approaches, especially those focused on 16S ribosomal RNA (rRNA) sequence diversity, have become popular as they enable r...
