genetic erosion

Each has contributed to the massive genetic erosion of the food chain.

By far, there is no threat of genetic erosion.

Genetic erosion is thought to have occurred as well.

The ability to supply that time, he said, is what is threatened by genetic erosion in crops.

Genetic erosion occurs because each individual organism has many unique genes which get lost when it dies without getting a chance to breed.

"If traditional growers abandon corn production - as the Nafta strategy foresees - then even more significant genetic erosion will occur," he said.

Rice planted in Hani terraced fields is extremely diverse even though it has been subjected to genetic erosion.

Genetic erosion, a problem that can happen in species with inadequate genetic diversity (including due to inadequate gene flow)

Formerly huge gene pools of various wild and indigenous breeds have collapsed causing widespread genetic erosion and genetic pollution.

The major driving forces behind genetic erosion in crops are: variety replacement, land clearing, overexploitation of species, population pressure, environmental degradation, overgrazing, policy and changing agricultural systems.

Apart from anything else, the use of GMOs will result in the genetic erosion of non-genetically modified varieties, with unforeseeable consequences for biodiversity.

Genetic erosion coupled with genetic pollution may be destroying unique genotypes, thereby creating a hidden crisis which could result in a severe threat to our food security.

After two years of negotiations with the Commission, focusing in particular on the certification of seed which is severely affected by genetic erosion, we were able to achieve success.

A recent study of native Prunus fruticosa stands in northern Poland finds it is disappearing there by "genetic erosion" or "disappearance of typical morphological characters".

These cause repeated damage to the forest, including saplings of desirable species, and lead to the problem of genetic erosion of the crop, and are also difficult to administer.

With advances in modern bioscience, several techniques and safeguards have emerged to check the relentless advance of genetic erosion and the resulting acceleration of endangered species towards eventual extinction.

Since the indigenous breeds are often well-adapted to local extremes in climate and have immunity to local pathogens this can be a significant genetic erosion of the gene pool for future breeding.

The matter in question concerned the adoption of a simplified certification system for conservation seed which was intended at the very least to restrict the genetic erosion of threatened species of agricultural plants.

All the endangered species of the world are plagued to varying degrees by genetic erosion, and most need a human-assisted breeding program to keep their population viable, thereby avoiding extinction over long time frames.

The smaller the population is on a relative scale, the more magnified the effect of genetic erosion becomes, as weakened individuals from the few surviving members of the species are lost without getting a chance to breed.

The term genetic erosion is sometimes used in a narrow sense, such as for the loss of alleles or genes, as well as more broadly, referring to the loss of varieties or even species.

Any deviation from the principle that sowing seed which contains GMOs must not be marketed will result, apart from anything else, in the genetic erosion of non-genetically modified species and varieties, with unforeseeable repercussions for biodiversity.

Knowledge of the origins of crop plants is important in order to avoid genetic erosion, the loss of germplasm due to the loss of ecotypes and landraces, loss of habitat (such as rainforests), and increased urbanization.

Genetic erosion is a process whereby an already limited gene pool of an endangered species of plant or animal diminishes even more when individuals from the surviving population die off without getting a chance to meet and breed with others in their endangered low population.

In South America, the mahoganies, Swietenia spp., were much sought after, so that today, they have suffered through genetic erosion to such an extent that often they are not worth exploiting, only those of poor form having been left in the forests to set seed.
