Genetic Structure Of Grass Carp Populations In The Missouri And Mississippi River Basins, Usa, Bobbi M. Adams, Katie N. Bertrand, Michael L. Brown, Donald Auger
Genetic Structure Of Grass Carp Populations In The Missouri And Mississippi River Basins, Usa, Bobbi M. Adams, Katie N. Bertrand, Michael L. Brown, Donald Auger
The Prairie Naturalist
We provided an early characterization of the genetic structure of the grass carp (Ctenopharyngodon idella) population as it expands its distribution in both the Missouri and Mississippi River basins. Further, we provided initial comparisons of allelic richness at 17 polymorphic microsatellite markers between 56 grass carp from the USA, and six from the Yangtze River in China. The number of alleles per locus ranged from two to eight and size ranges of alleles for fish collected from the invaded and native ranges were similar (P ≤ 0.001; 107–226 bp) to those previously reported in the literature. Distance-based clustering …
A Model System In Landscape Genetics – The Insect Inhabitants Of Pitcher Plants, Gordana Gojko Rasic
A Model System In Landscape Genetics – The Insect Inhabitants Of Pitcher Plants, Gordana Gojko Rasic
Electronic Thesis and Dissertation Repository
Landscape genetics is a rapidly growing field that investigates how landscape and environmental features interact with microevolutionary processes to give rise to spatial genetic variation in populations. The ability to predict landscape effects on genetic patterns has been limited by the lack of studies conducted on more than one species, over multiple spatial scales and in replicated landscapes. A system that allows for such studies are the insect inhabitants of the purple pitcher plant (Sarracenia purpurea): the pitcher plant flesh fly (Fletcherimyia fletcheri), the midge (Metriocnemus knabi) and the mosquito (Wyeomyia smithii). In this thesis, I worked towards developing this …

Juniperus procera is economically highly important but threatened tree species. It is the only species among 67 taxa in the genus Juniperus that naturally grows in Africa and south of the equator extending up to 18°S in Zimbabwe. Ethiopia is assumed to host the largest J. procera populations, which are also believed to have high genetic variation owing to their wide ecological amplitude. This study assessed genetic variation at AFLPs of J. procera populations in the Ethiopian highlands. In the study six populations, namely Chilimo, Goba, Menagesha-Suba, Wef-Washa, Yabelo and Ziquala were included. A total of 20-24 trees from each …

Ackee (Blighia sapida) is a native multipurpose species important for the livelihoods of the rural populations in Benin. Trees are found in natural forests or are managed by farmers in different traditional agroforestry systems. Genetic variation at amplified fragment length polymorphism (AFLP) markers, four nuclear microsatellites (nSSRs) and one chloroplast microsatellite (cpSSR) were investigated in 279 individuals from six wild and eight cultivated populations from Benin. The AFLP data revealed moderate levels of diversity of ackee in Benin (mean diversity values are proportion of polymorphic loci = 52.8% and Nei's gene diversity = 0.157, for 375 AFLP fragments). The mean …
