Rapid genetic erosion in pollutant-exposed experimental chironomid populations
Environmental Pollution, 2009Few studies have evaluated how effectively environmental contamination may reduce genetic diversity of a population. Here, we chose a laboratory approach in order to test if tributyltin (TBT) exposure at environmentally relevant concentrations leads to reduced genetic variation in the midge Chironomus riparius.

Contaminant driven genetic erosion: A case study with Daphnia longispina
Environmental Toxicology and Chemistry, 2012Abstract Natural populations exposed to pollutants are predicted to experience a loss of genetic diversity, especially through genetic drift, gene flow (emigration), and/or selection (as sensitive genotypes may be lost). In the present study, the authors discuss the use of selectable markers and neutral markers to evaluate a contaminant ...

Genetic Diversity and Erosion in Hevea Rubber
2015Genetic diversity keeps the soil fertile, recycles all nutrients, and cleans the air and water. The richer the genetic baggage, the higher shall be the capacity to fight different fungi, virus, or bacteria. Like other essentials, rubber is an industrial commodity that is indispensable to humans with more than 55,000 vivid products made from it.

Genetic Aspects on Erosive Tooth Wear
Erosive tooth wear is a gene-environmental model. It requires the exposure to acids, typically from the diet or from the gastric content of the host, and shows variation among individuals and populations, which suggests it to be determined by more than one gene, each with small individual effects.openaire +2 more sources
Genetic erosion over time of rice landrace agrobiodiversity
Plant Genetic Resources, 2008Changes in global biodiversity at the genetic level have proved difficult to determine for most organisms because of lack of standardized, repeated or historical data; this hampers the attempts to meet the convention on biological diversity (CBD) 2010 targets of reducing loss of genetic diversity, particularly of crop species. For rice, where germplasm

Wild or cultivated plants used in traditional and modern medicines are categorized as medicinal plants (MPs). Out of over 70,000 MPs, 3000 are traded and 900 are cultivated. Fragmentation/loss of habitats, unsustainable harvests, excessive grazing, invasive species, pollution, and climate change are destroying genetic diversity.

Genetic erosion of pasture and forage legumes in the Mediterranean basin
1999p ]Genetic erosion occurs as a result of disruption of the natural habitat by humankind or through the replacement of traditional landraces or ecotypes by modern cultivars. It may occur because of a decline in a species’ diversity through the reduction of its geographical distribution or through the complete loss of a species.

Mind the lag: understanding delayed genetic erosion
The delay between environmental changes and the corresponding genetic responses within populations is a common but surprisingly overlooked phenomenon in ecology, evolutionary and conservation genetics. This time lag problem can lead to erroneous conservation assessments when solely relying on genetic data.Gargiulo, Roberta +2 more
