Emperor penguins are threatened due to climate change and Over 90% of Emperor Penguins Will Be Quasi-Extinct By 2100 If Current Antarctica Sea Ice Loss Rates Persist. Four new emperor penguin colonies have been identified in Antarctica by satellites which brings the number of known nesting sites around the White Continent to 66. This is good because even though they are being affected greatly by the melting ice new colonies are still being discovered. This brings the estimated population to around 550,000. with these discoveries scientists believe they now know the whereabouts of all of the remaining breeding pairs, this is also vital information for conservationists who are monitoring the species.
Scientists from the University of Exeter found that Meadow Brown butterflies have fewer spots if they develop in warmer weather. The change, which helps them blend in to a browner landscape, means that some species might not move north but stay where they are. Females that developed at 11°C had six spots on average, whereas those that developed at 15°C had just three. This means that if temperatures around the world continue to rise, this species of butterfly could become less spotty possibly changing the way it camouflages itself and stays safe from predators. They also found that temperatures did not affect the males the same way it did with the females.
A survey of nesting sites revealed a sharp increase in the amount of green sea turtle nests this year with volunteers counting more then 74,000 nests, a staggering 40% increase from 2017s record. The increase is most likely due to the conservation measures put in place after green sea turtles were listed under the endangered species act in 1978.
The catch is though, the sex of a baby sea turtle is not determined by its DNA but by the temperature of the sand in which its egg develops. cooler temperatures mean males and warmer means females. This is means that due to global warming most of the hatchlings are female. This will be a boom for the sea turtles as females can lay between 2 and 9 clutches of a 110 eggs each in a season but research suggests that climate change will outstrip the adaptive advantage of feminization.
