The number of critically endangered Gorilla gorillas has been significantly reduced over the past few decades, which has led to a loss of genetic diversity that now endangers the survival of this species.
Reducing the population size caused by inbreeding
In a new study published in the journal Current biology On Thursday, Dalén's love for the Swedish Natural History Museum and colleagues sequenced genomes from several specimens of eastern gorillas collected a century ago.
They then compared the results with those of the living eastern gorilla, also known as Gauer Gorillas, living in the Democratic Republic of the Congo.
The results showed that Grower gorillas have accumulated harmful mutations, since genetic diversity of species has dropped significantly in just a few generations.
Gorilla's population in Gorilla has fallen by 80 percent over the last few decades due to the loss of poaching and habitats.
Reducing the number led to an increase in the incidence of inbreeding because relatives are more likely to face smaller populations. This resulted in loss of genetic diversity and harmful mutations.
Dalén and his colleagues identified several potentially harmful mutations that have increased more frequently over the past four to five generations of Grauer's gorillas.
Some of them have been found in genes that affect male fertility and resistance to disease. These changes leave the species less capable of adapting to new diseases and changing the environment.
The researchers also identified mutations that lead to loss of functions in finger and leg development, which may explain why some Grauer gorules have merged numbers.
Dahlen and his colleagues say the findings emphasize the need to address the collapse of the Gorilla population of Grower. Today there are less than 4,000 species, and Grower gorillas are now listed as critically endangered.
"This recent increase in harmful mutations really highlights the need to change the current decline in the population of Gorer Gorers," Dahlen said.
Other species are also at risk
The researchers also warned that there may be other species that may suffer the same fate as a result of the population's decline.
"Many species have suffered a serious decline in the population in the last centuries and may therefore face similar genomic consequences as explained here for Graer burners. In species with shorter generation time, such consequences may be more severe due to faster genomic changes "the researchers wrote in their study.
