Pacific herring show an abrupt genetic discontinuity in the central North Pacific that represents secondary contact between refuge populations previously isolated during Pleistocene glaciations. Paradoxically, high levels of gene flow produce genetic homogeneity among ocean-type populations within each group. Here, we surveyed variability in mtDNA control-region sequences (463 bp) and nine micr...

We isolated and characterized 60 novel microsatellite markers from the closely related oldfield mouse ( Peromyscus polionotus ) and deer mouse ( Peromyscus maniculatus ) for studies of conservation, ecological, quantitative and population genetics. We assessed all 60 markers in a wild population of Peromyscus polionotus rhoadsi ( N = 20) from central Florida and found an average of nine alleles...

The long-term persistence of forest-dwelling caribou (Rangifer tarandus caribou) will probably be determined by management and conservation decisions. Understanding the evolutionary relationships between modern caribou herds, and how these relationships have changed through time will provide key information for the design of appropriate management strategies. To explore these relationships, we ...

The analysis of polymorphic microsatellites is relevant for forensic, paternity testing and to study genetic admixtures and the genetic relationships between populations. Colombia has the second highest number, after Brazil, of Amerindian tribes in America (around 81) followed by Mexico (68 tribes) and Venezuela (20 tribes). Contrary to other genetic markers such as HLA and blood groups, Short ...

Understanding how a monophyletic lineage of a species diverges into several adaptive forms has received increased attention in recent years, but the underlying mechanisms in this process are still under debate. Postglacial fishes are excellent model organisms for exploring this process, especially the initial stages of ecological speciation, as postglacial lakes represent replicated discrete en...

The development of microsatellite DNA markers for use with butterflies and moths is extremely difficult for no apparent reason. New findings demonstrate that many lepidopteran microsatellite sequences exist in multiple copies in the genome, and have similar or almost identical flanking regions. These findings provide a compelling explanation for the low efficiency of microsatellite isolation in...

Purpose: Little information is available on genetic and epigenetic changes in duodenal adenocarcinomas. The purpose was to identify possible subsets of duodenal adenocarcinomas based on microsatellite instability (MSI),DNAmethylation,mutations in theKRAS andBRAF genes, clinicopathologic features, and

PREMISE OF THE STUDY Microsatellite loci were isolated from four species of Viburnum (Adoxaceae) to study population structure and assess species boundaries among morphologically similar South American Viburnum species of the Oreinotinus clade. METHODS AND RESULTS Using a microsatellite-enriched library and mining next-generation sequence data, 16 microsatellites were developed. Each locus wa...
