Bad news from Australia due to climate change
A new study on the population genetic of Australian green beans has shown that due to the increase in temperatures associated with climate change, one of the largest populations of this species that has more than 200,000 nesting females – could be compromised unless the number males.
It is emphasized that the rise in temperature in Queensland north of climate change is the main cause of the change in egg incubation temperature that determines sex habits. Namely, a warmer nests bring more females to the world.
There are two genetically separate populations of green groves on the Cape. One of them is replicated at the southern end, and the other nest in the north, mostly on the islands Raine and Moulter Cay.
Scientists have studied the wishes in the Howick archipelago where both of these food populations used genetic and endocrinological tests to determine sex habits and nesting habitats. Research has been carried out within the aRivers to Reef to Turtles project conducted by WWF Australia.
Tests have shown that as many as 99.1 percent of Juvenile, 98.8 percent of Subadult and 86.8 percent of adult Desires from those warmer northern beaches – the female sex. Dr. Michael Jensen of the National Oceanic and Atmospheric Administration says that in the northern part of the Great Coral reef for the last 20 years, females are mostly females.
"This study is very important because it brings new knowledge of what these incredible animals are facing," explains Jensen. He points out that "knowing the current gender ratio in the adult population and how this ratio should look in the next 5, 10 and 20 years essential for the survival of green iron."
It also emphasizes that scientists are already considering certain protection measures that could lead to an increase in the number of males in the population, as would be a shade on the beach.
"Although a large coral reef is significantly affected by climate change, from coral whitening to the aforementioned gingival problems, the impact of climate change is not only reserved for Far East Australia. Unfortunately, changes in the spread of invasive species from warmer seas are also visible in the Mediterranean Sea. One such species is a tropical fish lion that arrived in the Mediterranean from the South Pacific and the Indian Ocean, "said WWF Adria Patrick Krstinić, an expert on marine issues.
