Sea Turtles Are Turning Female Because of Rising Temperatures

The warmer the temperature is, the bigger probability that hatchlings will turn female.

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.

Tragic Moment Baby Rhino Tries to Suckle From Dead Mother Killed By Poachers

Wake up mom, I’m hungry!

A heartbreaking moment of a calf trying to suckle milk from her dead mother was caught in camera. The older rhino was, unfortunately, put into demise after being hacked off by poachers.

The video was filmed at a national park located in South Africa. It shows a younger rhino desperately trying to feed on its dead parent. The latter can be seen lying unresponsively. This is reportedly the 11th killing at the said site, and it all happened in just four weeks.

This Company Lets You Install Observational Beehives In Your Living Room

Not only will you see bees in action, you will also get to understand their crucial role in an urban setting!

The sad reality that we are facing today is the consistent decline in the bee population. Yes, this is true – and it has been that way for a long time already. Unfortunately, among the known causes of bee population decline are the loss of habitat and modern industrial farming methods.

If you think this is the least of your problems, then you certainly do not know a thing or two about nature. You see, bees are the ones responsible for pollinating most of the plants on the planet. And these plants, apparently, are the kinds that we human beings rely upon food. If not for these creatures, it is almost impossible for this cycle to happen. In order to encounter this nightmarish event, experts have come up with a couple of innovative solutions. BEEcosystem, in particular, has developed a system of wall-mounted observation hives, all of which can be easily expanded in a hexagonal, honeycomb style.
