The critical number of the Grauer's gorilla is significantly reduced in the last decades, due to the loss of the genetic diversity that threatens the survival of the species.
The size of the population decreases to degeneration
In the new study published in the journal Current biology On Thursday, Love Dalen, Swedish Museum of Natural History, and colleagues made a sequence with a species of eastern gorilla that had been gathered for a century.
Afterwards, the results were compared to the Eastern gorilla, also known as the Grauer gorilla, which lives in the Democratic Republic of the Congo.
The discovery shows that Grauer's gorillas have accumulated harmful mutations, with the genetic diversity of species almost descending from generation to generation.
The Graiber's gorilla has fallen by 80% in recent decades due to poaching and habitat losses.
The decline in the number was a degenerative occurrence, as relatives are in proportion to the smaller population. This, at the same time, has lost genetic diversity and harmful mutations.
Dalen and coworkers Grauer's gorilla had the potential to increase the potential for mutation in the last four or five generations.
Some of them have been found in genes that cause male fertility and endurance. These changes allow species that are not capable of adapting to new diseases and environmental changes.
Researchers have also identified mutations that cause finger loss and development genes, which is why some gorillas of Grauer blend some numbers.
Dalen and colleagues said the findings stand out in order to deal with the inadequate populations of Grauer's Gorilla population. There are currently less than 4,000 species and Grauer's gorilla is critically endangered.
"The latest growth in harmful mutations really highlights the need to return to declining the lifeblood of the gorilla Grauer," Dalen said.
Other species are also at risk
In addition, researchers have warned that other populations may have fate as well as other species.
"Many species have had a serious fall in population over the last few decades and, as a result, they can face genomic consequences similar to gorilla genders. In severe genes, the serious consequences could be serious as a result of faster genomic changes," researchers wrote in their studies.
