Consequences of geographical habitats on population structure and genetic diversity in Campanula spp. [PDF]

open access: yes, 2010
Characterization of populations by means of DNA techniques provides a tool for precise identification and a quantitative estimate of genetic diversity, crucial in evaluation of genetic fragmentation within and among populations.

High Genetic Diversity and Low Differentiation of Michelia coriacea (Magnoliaceae), a Critically Endangered Endemic in Southeast Yunnan, China [PDF]

open access: yes, 2012
Michelia coriacea, a critically endangered tree, has a restricted and fragmented distribution in Southeast Yunnan Province, China. The genetic diversity, genetic structure and gene flow in the three extant populations of this species were detected by 10 ...

Genetic erosion in crops: concept, research results and challenges [PDF]

open access: yes, 2009
The loss of variation in crops clue to the modernization of agriculture has been described as genetic erosion The current paper discusses the different views that exist on the concept of genetic erosion in crops Genetic erosion of cultivated diversity is

Genetic diversity and genetic burden in humans

open access: yesInfection, Genetics and Evolution, 2006
We discuss categories of genetic diversity in humans. Neutral diversity, population differences in frequencies of genetic markers that we think are invisible to natural selection, provides a passive record of population history but is otherwise of little interest in human biology.

Distribution of genetic diversity in wild European populations of prickly lettuce (Lactuca serriola): implications for plant genetic resources management [PDF]

open access: yes, 2010
Genetic variation in Lactuca serriola, the closest wild relative of cultivated lettuce, was studied across Europe from the Czech Republic to the United Kingdom, using three molecular marker systems, simple sequence repeat (SSR, microsatellites), AFLP and

Genetic Selection and Conservation of Genetic Diversity* [PDF]

open access: yesReproduction in Domestic Animals, 2012
ContentsFor 100s of years, livestock producers have employed various types of selection to alter livestock populations. Current selection strategies are little different, except our technologies for selection have become more powerful. Genetic resources at the breed level have been in and out of favour over time.

High genetic diversity in the remnant island population of hihi and the genetic consequences of re-introduction [PDF]

open access: yes, 2010
The maintenance of genetic diversity is thought to be fundamental for the conservation of threatened species. It is therefore important to understand how genetic diversity is affected by the re-introduction of threatened species.

Genetic Diversity of Toscana Virus

open access: yesEmerging Infectious Diseases, 2009
Distribution of Toscana virus (TOSV) is evolving with climate change, and pathogenicity may be higher in nonexposed populations outside areas of current prevalence (Mediterranean Basin). To characterize genetic diversity of TOSV, we determined the coding sequences of isolates from Spain and France.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.
