Bonobos and Chimpanzees are thought to be our closest relatives, and when you watch this young bonobo play with water. Knowing this, it is perhaps not strange that researchers are finding that bonobos combine words in ways that sound very human. They are able to combine several sounds, to create a phrase, with more meaning than its individual parts.
This is something that was considered unique to human language. A simple example of this ability would be something like “brunette painter” is something that many animals can do – it is a person which is both brunette and a painter – however bonobos can combine them is such a way like a “good painter”, good is not another description, but instead changes the meaning of painter- the two words give more meaning together.
I have tried to write on Bonobos, relatively regularly on this website. This is for a variety of reasons. Being the last species of unique great ape to be found (species like the Tapanuli Orangutan have been discovered since, but the bonobo is far more distinct. Bonobos are female dominated society, and it is a far more peaceful society than with chimpanzee. Violence is rare, with bonobos using sex to deal with tension and conflict instead.
They did a great deal of analysis, recording hundreds of vocalisations. They identified 7 different calls, used in 19 different combinations and found that of these 4 followed the rules of human sentences (the other 15 have not been properly analysed as yet.
One example, was where Yelps are thought to mean “lets do that” while grunts are thought to mean “look at what I am doing” but when combined into a yelp-grunt it appeared to mean lets do what I am doing – and was often used to encourage other members of the group to build their night nests.
Bonobo are still loosing territory in the wild, and with their whole range restricted to just the Democratic republic of Congo, their population is far more fragile than many other great apes.
Visiting the Bonobos will give the country more reason to preserve them.
Last month, the Slovakian cabinet approved plans to cull around 1 quarter of the bear population in the country (currently at around 1300) after some high profile fatal encounters between humans and bears.
It is unclear what the actual carrying capacity of Slovakia, and indeed this is often the problem. The government decides what the carrying capacity is of the land, they set quotas for hunting them and they reap the money for hunting permits, as well as having to deal with any livestock predation. These different requirements are often lead to different groups having different desires and therefore results can be skewed to support a decision which is not in the best interest of the country or the population.
Having carrying capacity and population size done by truly independent researchers would help with this, but in most countries, this independence is not real, with the government holding the purse strings or similar power over future studies.
A reduction of a quarter, is a large step, will change the population makeup significantly and is likely to greatly disrupt bear tourism to the country.
Tourism revenue for this country has hovered between 1 and 2 billion dollars in recent decades, and while it is hard to pinpoint exactly how much of this is to do with wildlife, and particularly bear tourism, it is thought that a majority do some sort of ecotourism while in the country – therefore care must also be taken to not destroy this important income for the country.
I have missed writing regularly, but have been having some issues with this website. I am hoping that in the near future these will be resolved, and allow the website to reach some of its potential – however for now, back to this article.
The UK is recognized as one of the most nature depleted places on earth. never the less, there is wildlife in the shadow of humans. A very wide range of wildlife has been lost, as humans have not left the space – this is causing us issues, not least because there are no apex predators left.
Wild boar, however, were accidently released – they were bred for meat, and between a variety of escapes and intentional released populations, a wild population has been established in the UK. Domestic pigs are descended from wild boar – it is thouoght that they were domesticated twice, once in the near middle east around 8500 years ago, and again in China around 6500 years ago (though it should be noted that these dates are still pretty unclear. 8500 years is not a long time in genetic evolution, and as such they are still capable to interbreed, even though there is a significant difference in how these two groups live.
There is an estimated 2600 wild boar living in the UK. The largest populations are listed below, though it does not account for all of them
Forest of Dean: This area has the most established and largest wild boar population in the UK. The population is estimated to be around 1,200 animals.
Kent/East Sussex: This area has a population of 250-300 wild boar.
West Dorset: This population is estimated to be over 50 animals.
North Devon: This area has a smaller population, estimated to be between 50 and 100 wild boar.
Wild boar are incredibly important for the health of forests – wild boar turn soil in their search for roots and tubers, and this is perfect for the growth of new seedlings. Boar rootling areas are often full of tree saplings and shoots growing together. It is something that has been missed for a very long time, and the health of forests that the boar returns to is greatly improving.
The area that I live in, has a great deal of army land, and therefore, I believe that the area could support hundreds of boar, if not more.
This individual boar, is likely to be a young roaming male, and usually, the first visitor does not settle within an area, however, females also roam, and should a male and female meet, they are likely to become a breeding pair, and at that point the population can grow fast as a breeding pair (when they have some domestic pig genes in them) potentially having 3 litters of 10 or more a year.
Will a breeding population be established around here? It is still for the time being, chance, however at this breeding rate, it is quite conceivable for boar to be back across the UK within the next couple of decades. Pure wild boar would be better, however adaption back to living in the wild will likely slow their breeding rate relatively fast.
African elephant populations have risen and fallen incredibly fast over the last few centuries. It is estimated that as much as 20 million Savanah elephants roamed Africa in the year 1800, but in 1979 just 600,000 remained, and in 2016 just 415,000 live in Africa. At that point, over 100,000 had been poached in the previous decade.
Unfortunately, it is not merely a case of making more parks. Elephants are incredibly intelligent, but so called fortress reserves, are not good enough. Indeed, less well protected reserves, that are linked together by migration corridors, are far better for the elephant population, than the aforementioned fortress reserves.
These corridors have multiple benefits, from allowing elephants to leave overpopulated areas, to being able to move to places where food and water are available. It also means that the elephants can leave areas of heavy poaching, for instance the Virunga national park, where elephants virtually disappeared in the 1990s, but have started to return from Queen Elizabeth national park in Uganda, across the border.
Where animals cannot move, one often has a boom and bust kind of population dynamic. Now, it should be noted, that this is not always easy, as migration corridors are rarely completely empty of humans, so there is more conflict in these areas, never-the-less, it is clear that these corridors are essential, if these elephant populations are to survive into the long-term. Of course, it also leads to an interesting situation, where virtually all of the huge ecosystems in Africa are along borders, as this allows more than one country to share the cost.
Of perhaps greater worry, this population of 415,000 is both the African savannah and African forest elephant. Yet these two are completely separate species, African forest elephants are nicknamed the gardeners of the forest, and it is questionable whether it can survive as effectively in the long-term without their recovery. The African forest elephant had a population of 26 million in 1800, it is unclear how many are left, but what is clear, is that their population has collapsed in the last few decades.
This seems a very cheap and simple solution to roads, at least for primates. A standard motorway bridge in the UK can cost well over $1million (estimates suggest at least £890,000). This compares to a canopy bridge costing $5000 if even that much.
Each male Sumatran Orangutan needs 15 square miles, while females need at least 3 square miles. Therefore in order to have a significant population in an area of say 1000 individuals, you are talking about needing almost 10,000 square miles of rainforest that is connected. It is highly likely, in a 100 by 100 square mile block that there will be some roads crossing it. Therefore, these simple methods for connecting forest blocks could become more and more important.
It should be noted, that while this works for primates in areas like this, it will not help the Sumatran elephants, or rhino or tigers, which share some of these forests. Still, it might mean that larger bridges for other animals to cross could be less common, while still allowing primates to cross with ease?
Even before the study was started, it was known that some species are not male dominated. Above is a family of Bonobos, and these great apes live in a female dominated society.
Given our assumption that on male dominance, it is perhaps surprising, that only 58% of primate species have dominant males. Perhaps not surprising, as a result, every major primate group had at least one species which was female (or co-dominant) structures.
Indeed, with the gibbons (or lesser apes on this website, to check them out, click here to visit the home page, and then expand the species database, and click on lesser apes) all 5 species examined (there are a total of 20) have been classed as non-male dominant.
Amongst primates, this likelihood is (according to Lewis, the head of the study) relatively easily predicted, as tends to occur in the species, where there is little difference between the size of male and female members.
An example here, is clear: while a male gorilla can weigh twice that of a female, siamang gibbons only have males a couple of kg heavier than females – not surprisingly, while male gorillas are dominant, this is not the case with siamang gibbons.
It should be noted, therefore, that while 4 out the 5 species of great apes are male dominated (we assume this in humans as well, though, in the modern day, it would be hard to argue that we are not more of a co dominant species. Given that likely all the lesser apes (the gibbons) are more or less co-dominant, it follows, that even just looking at the apes, more are female dominant or co-dominant.
Killer whale or Orca: highly intelligent, inquisitive, caring of family, no wonder they fascinate us
The Southern resident killer whale population is on the brink of extinction, but it seems, not for the reason that people thought.
Found along the coast of Washington, Oregon, California, and British Columbia, this population is thought to number just 75, but births are rare, and often end in sadness. 2 calves have been born in the last 2 years, but both have died young. This year, the mother was seen carrying her dead infant for some time (draped across her snout).
It is thought that this population is in danger as a result of a collapse in the Chinook salmon which is an essential part of their diet. However, this theory is defeated, when we look at the Northern resident killer whale population, and notice that they appear to have less access to the salmon. There is lots of shipping noise in their home, which may mean that they are incapable of communicating, which would impact their ability to hunt,
It is true that the origins of their decline lie around 120 years ago, when blackfish (orca as they were then called) were both slaughtered and captured for marine parks. The population on stopped falling fast when Canada banned capture. So is this just the straw that broke the camels back?
Why do captive orca have drooping fins?
Drooping dorsal fins are occasionally seen in the wild, so the split is not totally solid, but it is true, that while most captive orca eventually have a drooping dorsal fin, this is a far rarer site in the wild (while not being unheard of).
The fin is supported by a tough protein called callagen, and it has been suggested that with captive orca spending more time at the surface, the higher temperature from the sun may degrade the protein.
Tahlequah has given birth again (famous for carrying her first calf after it died)
Tahlequah carried a former calf for 17 days after it died, and for more than 1000 miles. This means it is rather lovely to see that she has had another calf. However, the calf has already been observed being pushed by the mother and does not look healthy. The mother is very experienced, so it is hoped that she can succeed, but time will tell. This mother is part of the Southern resident population which i mentioned above, which is small and with few births in recent years. It is therefore very concerning to find that 2 related calves died so close together.
A new video shows a mother orca teaching her calves how to hunt
I should say, that the article I read suggested this was the first time that it had been seen, but the below clip is from several years ago. Even so, it is fascinating to see a mother actively teaching her offspring how to hunt/
Orca have been seen, for the first time off Chile, hunting dolphins
As can be seen from the video above, orca are known to hunt and eat dolphins in various places around the world. However, this behaviour has never been seen in this population, so they had to work out how to do it for themselves. While in the past they have been filmed eating sea lions (and using local boats to hide their approach), they have now been filmed hunting dusky dolphins.
The study was looking at the eating habits of orcas in the southern hemisphere, so as to be able to conserve them more effectively. It suggests that Chile Orca are turning to these food-sources. While Orca have been filmed harrasing or even killing porpoises and dolphins, this is the first time that they have been filmed eating them.
Orca facing uncertain future as the marine zoo shuts
Marineland Antibese near Cannes France, is shutting, after the French government brought in more strict rules of their care. The law was passed in 2021, but comes into force in 2026. It is thought that 90% of the visitors come to see the killer whales and other dolphins, so without them they are not viable.
It is unclear as to what will happen with the Orca. They are from Icelandic waters, but having spent so much time in captivity, would not be able to look after themselves in the wild. A deal had been made to send them to a Japanese park, but there was outcry as their treatment would be worse, so the French government blocked it. There is another zoo in the Canary islands. A facility in Eastern Canada has suggested netting off around 40 hectares of a sea bay for them, where they could live out their lives, in relative comfort, and yet still be looked after by a team of vets and other carers.
Something similar has happened before. Keiko was the orca from the film Free Willy, and was rescued from captivity in 1996 and released into a similar bay in Iceland in 1998. Having spent more time in the wild, though he was able to relearn some skills and in 2002 he left with some wild orca. He swam to Norway, but unfortunately died from an infection in 2003.
Upemba national park had virtually all its large mammals poached, but it is coming back (below is a 3 minute video about this decline).
Just a couple of years ago, 16 members of the Bakata Katanga militia suprised a party of 4 rangers within the park (close to the Upemba base camp). Lying in the south-east of the DRC, this reserve once teamed with life. Tens of thousands of elephants, alongside lins zebra and many other species roamed free.
Sumatran tigers are known to live in the Leucer ecosystem of Sumatra, but camera traps from the next door state in Aceh. This is exciting, as the population is dangerously low, but may be less low than we thought.
This does not change their conservation status, but may mean that they are more secure than we thought.
