The genetic diversity of animals and plants has declined worldwide over the past 30 years, and more than 600 species have been discovered.
This study, published in Nature Journal, found a decrease of two -thirds of the population in the survey, but urgent conservation efforts could even suspend or reversing genetic diversity. I focused on that.
Dozens of scientists have internationally reviewed 882 research in 628 kinds of animals, plants, fungi, and chromists (types of organisms) between 1985 and 2019. Forming a “most comprehensive survey” of changes in genetic diversity. In the past.
Professor Katherine Grober, a senior researcher in the research, says that the population can adapt due to changes in the environment, mentioning the variety of individuals in the same species, referring to the diversity in the species. I mentioned.
“If a new illness comes or a thermal wave, there may be individuals in the population with a specific characteristic that can withstand those new conditions,” she said.
“These characteristics are inherited by the next generation, and the population will last, not extinct.”
Maintaining the genetic diversity of the wild and kept species has formed one important element of the goal adopted in the Biodiversity Council in 2022.
Grovers stated that many of the main causes of genetic diversity were the same as the decrease in groups.
Researchers have discovered 65 % of the research -based ecology disorders, such as human harvest, harassment and land use change. However, even if the disability had not been reported, he said that he had a loss of genetic diversity, suggesting a “background level of genetic diversity of the whole species.”
“I believe this represents a crisis of a general biodiversity that the planet is facing.
However, she emphasized some cases where adjusted conservation strategies have improved genetic diversity.

This included a project in Western Australia to establish a new population of Golden Bandic, a threatening species. “Understand where they choose animals, and use genetic research to monitor those groups, indicating that they can maintain the genetic diversity of those groups through multiple generations. I was able to do it, “said Grueber.
In the United States, conservative biologists could maintain the genetic variability of the Prairie dog in Kuroo by crushing insecticides, preventing the fleas from spreading the fleas during the occurrence. “The population was prosperous, and the movements were moved more in the landscapes, so they were able to cross with other private dogs,” said Grueber.
In Scandinavia, the group of the Arctic foxes is decreasing for fur trade, and we are currently facing intense competition with red foxes for prey, but supplementary feeding and removing red foxes are. It led to an increase in genetic diversity there.
“It is important to maintain the genetic diversity of natural systems,” said Grueber. “We have a way to function.”
Meta analysis contains 141 species and contains more than 500 animal species.
