Kakapo is a critically endangered species; there were only around 50 of them left living on Stewart Island of New Zealand in 1995, and now there are around 200 of them on the island. Scientists worry the population of kakapo is too small and inbreeding will cause more harmful mutations and lead to genetic diseases. However, a recent study found that there are actually fewer harmful mutation in their genes than scientists expected, some original harmful mutations have disappeared as well.

A recent Bristish dragonfly study discovered since 1970, around 40% of the species increased in numbers, while 11% decreased. Among all dragonfly species in UK, six of them moved north to UK due to climate change. Experts worry these species may compete with native species for resources and create threats. Similar trends was observed in Canada and US as well.
20 tons of dead fish and crustacean were washed ashore recently in Mar Menor lagoon in southeastern Spain. That region is one of the major agricultural production area. Large amount of pollutants that contains nitrogen, phosphorus and other chemical fertilizers entered the lagoon, causing algae blooms which consume oxygen in water and lead to suffocation on marine creatures. the public gathered to protest and urge for investigations on the problem; Spanish authorities are going to tighten a ban on the use of harmful fertilizers.
In UK, a greyhound donated its blood 22 times in the past six years and helped around 88 dogs. But it has recently reached the age of 9 and has to retire as donation is only taken from dog aged from one to eight. Negative blood can be given to any dog but only around 30% of the dogs has this blood type; and this greyhound is one of them.

Peatland at Holcombe Moor in UK has dried out because of pollutions, fires and overgrazing in the past 1Peatland at Holcombe Moor in UK has dried out because of pollutions, fires and overgrazing in the past 150years. To restore the peatland, 3500 scallop-shaped bunds were installed by National Trust to help trap water to keep the peatland wet as well as absorbing CO2. This project hopes by improving the health of the peatland, it can boost biodiversity can be boosted to attract more wildlife to inhabit and prevent flooding.
British and Danish research groups discovered a way to detect DNA from the air and tested it in a zoo. They were able to found DNA of different animals including mammals, birds, reptiles and even fish in the pond. Even though they are not able to detect the releasing time of the DNA, and not able to know how long it survives in the air, but this discover will help to detect animal presence in a more flexible and less disturbing way.
A study found that fruit bats will make irrational choices when picking on food similar to human behavior. When a fruit bat is offered a ripe papaya and ripe banana, they don’t have a strong preference for either; but when a unripe banana is added in as a third option, they would prefer the ripe banana. This shows that adding the decoy has changed their behavior.
The harassment of dolphins, seals and whales are increasing in the Moray Firth in northern Scotland. people with sailing boats and kayaks are cashing and harassing dolphins intentionally. These actions are creating stress, affecting their feeding behaviours and can cause injuries to these dolphins.
