Impact of parasite sympatry on the geographic mosaic of coevolution.
Slave-making ants are specialized social parasites that steal the young from colonies of their host species to augment their slave supply. The degree of parasite-host specialization has been shown to shape the trajectory along which parasites and hosts coevolve and is a prime contributor to the geographic mosaic of coevolution. However, virtually nothing is known about extrinsic influences on p...
متن کاملCoevolution: The Geographic Mosaic of Coevolutionary Arms Races
Coevolutionary arms races between species can favor exaggeration of traits for attack and defense, but relentless escalation of these arms races does not necessarily occur in all populations.
متن کاملCoevolutionary Biology: Sex and the Geographic Mosaic of Coevolution
Natural selection can favor the coexistence of sexual and asexual forms of a species even within a single ecosystem, when hotspots of coevolution between hosts and parasites occur next to coldspots.
متن کاملSpecific Hypotheses on the Geographic Mosaic of Coevolution
Coevolution is one of the major processes organizing the earth’s biodiversity. The need to understand coevolution as an ongoing process has grown as ecological concerns have risen over the dynamics of rapidly changing biological communities, the conservation of genetic diversity, and the population biology of diseases. The biggest current challenge is to understand how coevolution operates acro...
متن کاملGenome divergence and diversification within a geographic mosaic of coevolution.
Despite substantial interest in coevolution's role in diversification, examples of coevolution contributing to speciation have been elusive. Here, we build upon past studies that have shown both coevolution between South Hills crossbills and lodgepole pine (Pinus contorta), and high levels of reproductive isolation between South Hills crossbills and other ecotypes in the North American red cros...
