Plant Genetic Resources: Selected Issues from Genetic Erosion to Genetic Engineering [PDF]
Journal of Agriculture and Rural Development in the Tropics and Subtropics, 2008 Plant Genetic Resources (PGR) continue to play an important role in the development of agriculture. The following aspects receive a special consideration:1. Definition. The term was coined in 1970.

Microevolution due to pollution in amphibians: a review on the genetic erosion hypothesis
Environmental Pollution, 2015 The loss of genetic diversity, due to exposure to chemical contamination (genetic erosion), is a major threat to population viability. Genetic erosion is the loss of genetic variation: the loss of alleles determining the value of a specific trait or ...

Genetic erosion in maize's center of origin. [PDF]
Proc Natl Acad Sci U S A, 2014 Significance Unlike germplasm banks, on-farm conservation allows crops to evolve continuously in response to changing conditions. Agricultural adaptation to climate change, emerging pests, and diseases thus depends on conserving crop genetic diversity in situ.

Assessing maize genetic erosion [PDF]
Proceedings of the National Academy of Sciences, 2014 Dyer et al. (1) report a rapid decline in maize varieties grown by Mexican farmers, arguing that their results are in contrast with previously reported work. We believe that the support for this rapid decline is weak, and that the contrast with previously reported work is false.

Mapping erosion-corrosion of carbon steel in oil exploration conditions : some new approaches to characterizing mechanisms and synergies [PDF]
, 2010 Erosion by solid particles in oil/water slurries is a technologically important area. In such conditions, it is necessary to distinguish between the effects of the sand, aqueous environment, and the oil.

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

The “genetic erosion” of the soil ecosystem
International Soil and Water Conservation Research, 2013 AbstractThis paper takes into consideration the influence of human activities on the loss of pedodiversity in a Mediterranean area due to large scale farming. In particular it examines the quantitative and qualitative soil changes in a period of 53 years (from 1955 to 2008) evaluating the loss of soil diversity at soil subgroups level of the USDA Soil ...

Mapping erosion-corrosion of carbon steel in oil-water solutions : Effect of velocity and applied potential [PDF]
, 2012 In this study, the combined effects of erosion and corrosion on carbon steel were investigated in three environments containing crude oil, reservoir water, and a mixture of both solutions at a range of applied potentials, velocities and impact angle. The

Cogent Food & Agriculture, 2021 Information on the diversity changes occurring in farmers’ field overtime is very important for effective genetic resource conservation and use. Thus, this study was initiated to investigate the phenotypic diversity changes between the current (2017) and
