1. Comparison of methods for detecting bottlenecks from microsatellite loci

Author:
Williamson-Natesan, Ellen G.
Source:
Conservation genetics 2005 v.6 no.4 pp. 551-562
ISSN:

Subject:
alleles; heterozygosity; microsatellite repeats; models; mutation; population size
Abstract:
... This paper describes simulation tests to compare methods for detecting recent bottlenecks using microsatellite data. This study considers both type I error (detecting a bottleneck when there wasn't one) and type II error (failing to detect a bottleneck when there was one) under a variety of scenarios. The two most promising methods were the range in allele size conditioned on the number of alleles ...

2. Conservation corridors affect the fixation of novel alleles

Subject:
alleles; anthropogenic activities; extinction; gene flow; habitats; population growth; population size; simulation models
Abstract:
... Corridors are a popular tool for conservation of small populations. However, two purported benefits of corridors, increasing gene flow and providing a means for the recolonization of extinct patches of habitat (population rescue), may have unappreciated impacts on the likelihood that a new allele will become incorporated (fixed) within a population. Using a simulation model, I demonstrate that con ...

Abstract:
... The horned grebe (Podiceps auritus) population of the Magdalen Islands in the St. Lawrence Gulf (Québec, Canada) has declined sharply over the last decades. It is the only breeding population of this species in eastern North America with nearest breeding populations being >2500 km apart in western North America and Europe, We used three types of genetic markers: mitochondrial (mt) DNA ND2 sequence ...

Abstract:
... Low levels of genetic variation are thought to contribute significantly to the higher extinction rates of endemic island populations compared to their mainland counterparts. We used six microsatellite loci to compare the genetic structure of the endangered silver rice rat (Oryzomys argentatus) population in Saddlebunch Key, Florida to the mainland population of the closely related marsh rice rat ( ...

Abstract:
... Genetic diversity and differentiation were analyzed in 11 populations of Magnolia stellata (Sieb. and Zucc.) Maxim. (Magnoliaceae) in the Tokai district, Japan. Variation at four nuclear microsatellite (nSSR) loci was examined, three chloroplast microsatellite (cpSSR) markers were developed and 13 haplotypes identified. The 11 populations were divided into three groups (A, B and C). Each populatio ...

Abstract:
... The progressive decline in red squirrel (Sciurus vulgaris) numbers in Wales has led to conservation and reintroduction projects being established on the island of Anglesey. The recovery of the island's remnant wild population was initially successful, however concern remained over potential loss of genetic diversity resulting from an observed demographic bottleneck. We used mitochondrial DNA (mtDN ...

Heterozygosity and phylogenetic relationships were analyzed using eight microsatellite loci for nine freshwater and one anadromous populations of threespine stickleback Gasterosteus aculeatus from northern Japan. Fis values and Hardy-Weinberg tests indicated that nine of the populations were in heterozygote deficit. Furthermore, on-going isolation of most of the populations by artificial destructi ...

We compared variation in the mitochondrial control region, four nuclear introns and three microsatellite loci among194 murrelets from throughout their range except Washington and Oregon. Significant population genetic ...

Abstract:
... Populations of the endangered giant kangaroo rat, Dipodomys ingens (Heteromyidae), have suffered increasing fragmentation and isolation over the recent past, and the distribution of this unique rodent has become restricted to 3% of its historical range. Such changes in population structure can significantly affect effective population size and dispersal, and ultimately increase the risk of extinct ...

Abstract:
... Honey bee males and queens mate in mid air and can fly many kilometres on their nuptial flights. The conservation of native honey bees, such as the European black bee (Apis mellifera mellifera), therefore, requires large isolated areas to prevent hybridisation with other subspecies, such as A. m. ligustica or A. m. carnica, which may have been introduced by beekeepers. This study used DNA microsat ...

Two Puffinus shearwater species are endemic to the Mediterranean region: the Yelkouan shearwater P. yelkouan breeding in the central and eastern, and the critically endangered Balearic shearwater P. mauretanicus in the western, exclusively breeding at the Balearic archipelago. All individuals caught in Minorca, a Balearic breeding site, showed phenotypic traits of Yelkouan shearwaters. Ten birds f ...
