Invasion genetics of the Eurasian spiny waterflea: evidence for bottlenecks and gene flow using microsatellites.
The Eurasian spiny waterflea (Bythotrephes longimanus) is a predacious zooplankter that has increased its range in Europe and is rapidly invading inland water-bodies throughout North America's Great Lakes region. To examine the genetics of these invasions, we isolated five microsatellite DNA loci with between 5 and 19 alleles per locus. We sampled three populations where B. longimanus has been ...
متن کاملComputational Bottlenecks for Evolvability
Valiant (2007) proposed a computational model for evolution and suggested that evolvability be studied in the framework of computational learning theory. Feldman (2008) showed that Valiant’s evolution model is equivalent to the correlational statistical query (CSQ) learning model, which is a restricted setting of the statistical query (SQ) model. Evolvability in Valiant’s model has been shown t...
متن کاملPopulation bottlenecks
What are they? They occur when a wild population is reduced to a small number of individuals, and then increases again. They are typically caused by an environmental change such as unusual climatic conditions, or, increasingly, the actions of humans, as in over-hunting and habitat destruction. But if the population size is restored, everything ends up fine, surely? No. The small population size...
متن کاملRegulation of dendritic calcium release in striatal spiny projection 2 neurons 3 4 5 Abbreviated Title : Regulation of dendritic calcium
33 The induction of corticostriatal long-term depression (LTD) in striatal spiny projection neurons 34 (SPNs) requires co-activation of group I metabotropic glutamate receptors (mGluRs) and L-type 35 Ca2+ channels. This combination leads to the postsynaptic production of endocannabinoids that 36 act presynaptically to reduce glutamate release. Although the necessity of co-activation is 37 agree...
