Chloroplast microsatellites: measures of genetic diversity and the effect of homoplasy [PDF]

Molecular Ecology 14, 5 (2005) 1333-41, 2009
Chloroplast microsatellites have been widely used in population genetic studies of conifers in recent years. However, their haplotype configurations suggest that they could have high levels of homoplasy, thus limiting the power of these molecular markers.

Natural recovery of genetic diversity by gene flow in reforested areas of the endemic Canary Island pine, Pinus canariensis [PDF]

Forest Ecology and Management 244, 1-3 (2007) 122-128, 2008
The endemic pine, Pinus canariensis, forms one of the main forest ecosystems in the Canary Islands. In this archipelago, pine forest is a mosaic of natural stands (remnants of past forest overexploitation) and artificial stands planted from the 1940's. The genetic makeup of the artificially regenerated forest is of some concern. The use of reproductive

Lower genetic diversity in the limpet Patella caerulea on urban coastal structures compared to natural rocky habitats [PDF]

Marine Biology 156 (2009) 2313, 2009
Human-made structures are increasingly found in marine coastal habitats. The aim of the present study was to explore whether urban coastal structures can affect the genetic variation of hard-bottom species. We conducted a population genetic analysis on the limpet Patella caerulea sampled in both natural and artificial habitats along the Adriatic coast.

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]

Annual Review of Ecology, Evolution, and Systematics Vol. 44: 195-215, 2013, 2013
To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare. But if positive selection operates on many loci simultaneously, as has recently been suggested for many species including ...

The effect of multiple paternity on genetic diversity during and after colonisation [PDF]

PLoS ONE 8(10) e75587 (2013), 2012
In metapopulations, genetic variation of local populations is influenced by the genetic content of the founders, and of migrants following establishment. We analyse the effect of multiple paternity on genetic diversity using a model in which the highly promiscuous marine snail Littorina saxatilis expands from a mainland to colonise initially empty ...

Prevalence and genetic diversity of Parechovirus. [PDF]

Virus Res
Human parechovirus (HPeV) is a common virus that can cause severe infections in newborns. Due to the limited knowledge of the prevalence of HPeV in different cities in China and the unknown association between HPeV infection and clinical characteristics of newborns, this research investigated the epidemiological and clinical characteristics of HPeV ...

Determinants of genetic diversity [PDF]

Nature Reviews Genetics, 2016
Genetic polymorphism varies among species and within genomes, and has important implications for the evolution and conservation of species. The determinants of this variation have been poorly understood, but population genomic data from a wide range of organisms now make it possible to delineate the underlying evolutionary processes, notably how ...

Perspectives of genomics for genetic conservation of livestock [PDF]

, 2011
Genomics provides new opportunities for conservation genetics. Conservation genetics in livestock is based on estimating diversity by pedigree relatedness and managing diversity by choosing those animals that maximize genetic diversity.

Combining multiple markers significantly increases the sensitivity and precision of eDNA‐based single‐species analyses

Environmental DNA, 2023
The analysis of environmental DNA (eDNA) is becoming integrated as an established biomonitoring tool, often characterized by detection limits exceeding those of conventional counterparts. However, further improving the sensitivity of these methods may be

The Genetic Diversity of the Americas [PDF]

Annual Review of Genomics and Human Genetics, 2017
The history of the Americas involved the encounter of millions of Native Americans, Europeans, and Africans. A variable admixture of these three continental groups has taken place throughout the continent, influenced by demography and a range of social factors.
