This enormous temperature jump could have huge impacts. On 18th March 2022 scientist at Concordia research station on the east side of Antarctica. To put this leap in perspective, that would take a normal spring day in the UK, up to some of the highest temperatures ever recorded on planet earth.

The origin of elephants in Borneo is unknown. Known for hosting the smallest elephants in the world, there are 2 theories as to how the elephants got to the island. The first is that they were released by a ruler in the 17th century (The most rapid population growth ever seen was 7,1% after the end of poaching in a reserve in Tanzania, a population of 30 elephants could become 1000 in just 50 years) – if this was the case, then their loss would not be bad; and the second is that actually the elephants arrived on the islands hundreds of thousands of years ago (as high as 300,000 years).
It is increasingly agreed that the second one of these ideas is likely to be correct. Though having said this, genetic analysis suggests that the whole population started with just 28 elephants.
Just 1000 are found on the island at the current time.
All wildlife on Borneo is at threat, as the palm oil industry continues to demand increasing quantities of prime rainforest be cut down. As this happens, elephants are forced into human areas, in their search for food, and then into conflict.
The Borneo elephant has only recently been assessed by the IUCN red list as a separate subspecies, but it is hoped that this recognition might increase tourism on this species as well as conservation dollars to save this species from its slow slide towards extincion
These 3 groups do not intermix, and only very seldom, interbreed. These populations are found in the Southern Pacific, Northern Pacific and the North Atlantic and Mediterranean.
This naturally means that the great white sharp is far more at risk of extinction, than if all the great white sharks in the worlds oceans could interbreed.
These areas appear to be bounded by great ocean currents, which are rarely crossed. This is a problem, as if an individual population is lost, it makes it far more likely that distinct genetic information could be lost with it – take the Mediterranean great while shark population, which has seen a dramatic population decline from historic numbers, estimated at between 52% and 96% (areas like the Maramara sea, are known to have lost 96% of their population) depending on which study you read.
This makes local conservation far more essential, and we need to be careful to not loose any individual populations. There has been a great deal of worry for the great white shark population around South Africa, as they pretty much vanished in 2017, but appear to have returned in 2024. The disappearance of the great white was attributed to 2 orca which had become expert in hunting and killing these sharks – it should be remembered, that while great whites are often at the top of the food chain, they are hunted for food by orca. Whether these orca have gone back to eating something else, hence the great white shark return, is a question that does not appear to have been answered as yet.
The wolf disappeared from Holland around 1870, though their decline was rapid – in 1760 (just over 100 years before) people in Brabant talked of a wolf plague). In 2015, the wolf was first sighted in Holland, and while some people had said that Holland was to densly populated to allow the wolf to return, this seemed to be wrong. Wolves have returned to many of the countries around Holland, and so it seems quite odd to think that it wasn’t considered that they would cross into Holland.
In 2022, there were thought to be 4 packs of wolves (including 16 pups) as well as an individual wolf. This number has, however, grown fast in the time since, and the current number is thought to be 9 packs. What is even more exciting, it is predicted that the country can support between 23 and 56 wolf packs at a minimum – which as a wolf pack contains 6-7 wolves on average, means a total population of between 138 and 392. It should be noted, that this number is not likely to remain genetically healthy into the long-term, however Germany has a wolf population of over 1000, and while these are mostly based in the East of the country, wolves disperse great distances, so it is likely that genetic material will arrive naturally, relatively regularly. There is also a founding (if small) population of wolves in Belgium, thought to number between 15 and 24 (it is also predicted to grow by 30% a year.
There is a problem, the Hoge-Velue is one of Hollands biggest reserves, but it is owned privately. They have decided that wolves are not welcome, and are making efforts to kill those that get through their fence. This is because, without the wolf, deer are easily seen within the reserve, and they believe that the number of tourists will dry up, if it becomes hard to see the red deer, as well as the roe deer and boar.
I find this attitude rather baffling and perverse. Furthermore, when we were there last year, we spent time in the government owned reserve, which borders the Hoge-Velue, this is government owned, and wolves have settled here. I spent a number of nights within the reserve in a hide. I did not get to see a wolf (though I met a local who had a wide range of fantastic shots he had taken over the previous years), but while watching and waiting in the hide, I saw red and roe deer, as well as wild boar, in significant numbers. The idea that someone would believe that the amount of tourism visiting after wolves return would decrease, seems quite contrary to what usually happens elsewhere.
Wolves are a part of Hollands animal food web, and while it is likely to take some time to get used to living with them present once again, it is going to allow the whole ecosystem to thrive. I feel frustrated, that in the UK, we do not have a similar situation, where wolves can simply wander across an unmarked border. I do believe that in the end, wolves will return to the UK (our food web is horrifically out of balance because of a lack of predators), however, on the last occasion that it was debated, numbers from a very specific country were used to block any further discussion (Click here to read a previous article on this subject, or visit the wolf page here to get a complete list of all occasions that they have been mentioned on this site)
The beaked whale species are a family of rarely seen whales. Despite there being 22 species of beaked whale (which we know about) they are rarely seen, and some have only been described in recent years.
Why are they seen so rarely? because they have a record breaking ability to hold their breath being able to hold it for over an hour (reasonably regularly) and have been recorded in dives lasting over 100 minutes. After sightings of this species, the researchers did a search and analysis of sightings between 1980 and 2000. Just 108 sightings were made, accounting for 1125 individuals.

Life is hard in the Indonesian rainforest – compared to Africa and South America, there is very little to be found to eat (except in specific areas. As a result, orangutans become solitary, with the only time they are seen together is a mother with young, or a courting couple. Another problem, is demonstrated here – there is so little food to be had, that every food opportunity has to be realized. This has meant that orangutans have become the best climbers (followed by Chimpanzee and then Gorilla), as where ever the food is, it needs to be accessed.
It is true, that with tools, humans can become even better climbers (as can be seen from the image), which is taken from further up the tree than the orangutans have even climbed.

90% of their diet consists of fruit. Having said this, they are classed as omnivores and take a range of foods including shoots and grass seeds, fungi invertebrates, eggs carrion fish and small vertebrates such as rodents, small birds, frogs, lizards and snakes. While all of the ratite family can eat meat, Cassowaries are by definition the most omnivorous, and while other ratites will eat meat when other food is scarce Cassowaries take more meat than others.
While the southern Cassowary has part of its range on Australia, all three have their main range on New Guinea
Whaling went on for centuries, in many parts of the world. One of these was Iceland, where due to the latitude, it is often hard to grow much food. Iceland did not end whaling when it was banned by the international community, and since then have hunted and killed around 1800. They returned to hunting fin whales last year, but what is clear, is that not only do the Icelandic people not want to eat the whale meat, but there is little hunger for it elsewhere in the world. Indeed, whaling is incredibly expensive, and has only stayed afloat through government support.
Whales are essential to the worlds oceans, both through their fertilization through their waste, and the vast amounts of carbon that they sequester over their lives. For the foreseeable time we need every living whale we can have, in the fight against the damage which humans are doing to the planet.
Once so common that they were cooked as a national food on the island. Yet in just two decades, the animal is one of the rarest in the world, with an estimated population of just 21.
Growing to 20cm long and weighing over 1kg, it was one of Dominica’s apex predators. eating small mammals, snakes and other frogs.
It’s decline is notable, as its calls were formerly something that you heard across the island.
Now, silence from this frog has fallen across most of the island.
Initially, its decline was caused by a fungus, which impacted amphibians skin – important, as many amphibians breathe through there skin, and all breathe through their skin.
The breakout of this fugni led to a decline of 80% in just one year. Known to only occur on one other island (Montserrat), scientists urged strict quarantine measures to stop it arriving, but these warnings failed to have any effect.
A number of these frogs were removed in 2009 as the illness began to spread, and they are housed around the world in various zoos, such as London zoo.
In recent times, a few surviving individuals have been discovered. These appear to be naturally resistant to the chytrid fungus that is at fault.
Unfortunately, shortly after, hurricane Maria hit, and the population declined a further 80%, back into double digits.
Due to the lack of immunity to this fungus, it would appear that zoo individuals that were rescued back in 2009 are all irrelevant. Whether with such a small wild population, it is worth capturing more (it is possible that these new individuals could be bred with already captive individuals, bit this may not retain the immunity).
The remaining wild frogs are found in 2 populations, and neither are found on protected land. As such, the situation could change fast if land use changes would occur.
The conservationists in the wild are still working, but it is thought that there is only 2 years left to save the species from extinction.
This bear was filmed, gnawing on a bone from a takin, a species of wild cattle.
For a species which is thought to survive exclusively on bamboo, this would be strange behaviour.
However, pandas do not survive exclusively on bamboo as roughly 1% of their diet comes from other foods. In fact, their digestive system is typical of a carnivore, so the remaining 1% of their diet can include eggs, small animals and carrion – like this bone. Pandas are also known to forage in farmland for pumpkin, kidney beans, wheat and domestic pig food.
The thing is, pandas eat up to 38kg a day, which means that during the week, they eat around 3kg of food that is not bamboo. This is significant, and while much of this may well be other vegetation, if the time spent on other food sources was around 1% of the time, it would suggest at least 1 hour a week spent eating other things.
One must remember that their intelligence is on a par with Chimpanzee and gorilla -like other bears, so they are capable of working things out.
