Here’s a fascinating tidbit about sea turtles – their gender depends on temperature. The warmer the temperature is, the bigger probability that hatchlings will turn female. Because of global warming, the number of female sea turtles are increasing dramatically.
According to the study of researchers from the National Oceanic and Atmospheric Administration, California State University and Worldwide Fund for Nature Australia,:
“Combining our results with temperature data show that the northern GBR green turtle rookeries have been producing primarily females for more than two decades and that the complete feminisation of this population is possible in the near future.”
The warmer it gets, the more females are produced.
The study, which was published in Current Biology, examined two populations of the turtle species and found the group living further north in Australia were 99% female. Northern Australia is warmer than the rest of the country.
“With warming global temperatures and most sea turtle populations naturally producing offspring above the pivotal temperature, it is clear that climate change poses a serious threat to the persistence of these populations,” the researchers noted.
According to marine biologist Michael Jensen, the study’s lead author:
“You work on one of the biggest turtle populations in the world and everyone tends to think that means things are good. But what happens in 20 years when there are literally no more males coming up as adults? Are there enough to sustain the population?”
And it’s not just the reef’s turtle population that are at risk.
The Great Barrier Reef will not be saved despite government efforts if climate change continues, according to a report published last year in scientific journal Nature.
The Australian government’s initiatives to save the reef include improving water quality, updating fishing and shipping regulations, managing land use, and conserving the wildlife. But these efforts will all go to waste if sea temperatures will continue to rise, according to researchers from James Cook University in Queensland.
Abnormally high sea temperatures cause coral bleaching, in which corals discharge tiny photosynthetic algae called zooxanthellae, which turns the coral white, and often killing it. In 2016, more than two-thirds of corals killed in some areas. Almost 90% of surveyed reefs were affected, making it the worst on record.
Million of Crabs in Christmas Island Marches Back to the Jungle After Mating Season
The tide of crustaceans crawling all over the beach is so thick it can be seen from Google Earth.
Once a year, millions of baby crabs can be seen making their way to the beaches of Christmas Island during mating season. These crabs came from the ocean and are heading towards the jungle where the adult crabs live.
The march produces a sea of crimson, a sight so amazing that it has become a tourist attraction. The tide of crustaceans crawling all over the beach is so thick it can be seen from Google Earth. Just try to imagine that!
The annual mating season of the crabs attracted tourists to Christmas Island.
Woman Performs Surgery On A Butterfly With Broken Wings – And It Worked!
Despite having no medical expertise, she was able to perform a successful wing transplant.
Monarch butterflies are perhaps one of the most interesting species, with wings that seem to be a work of art. They can only live from two weeks to five months the most. Apparently, there was a certain butterfly on a brink of death. It basically came into this world with a defected wing.
Romy McCloskey vowed to raise three monarch butterflies, but one of these creatures had a problem on its wings. Determined he could save it, Romy turned her home into a mini operating room. She even used common household items in performing a wing transplant. Yes, that's right – a wing transplant!
What is more interesting is the fact that Romy had no medical expertise whatsoever. She was a “professional costume designer and master hand embroiderer,” though. Still, she managed to make the operation successful. ...
Amazing Survival Tactics Made Frozen Alligators Survive the Winter Blast
They hate the freezing cold as much as we do.
Most creatures, human or not, will surely perish in extreme frozen conditions. Case in point, you would definitely NOT expect alligators to survive being frozen in a icy pond. Surprisingly, however, these alligators in Shalotte River Swamp Park in North Carolina did. They avoided being frozen to death, thanks to awesome survival tactics.
A video showed these alligators with their snouts sticking out of the frozen pound. They look dead at first glance, but according to the park's manager, they were actually alive and well.
