Through a number of different processes oceans can be a significant carbon sink. An increase in the carbon content of water does acidify it so this is not something we are interested in, but in healthy seas there is a great deal of plankton and that plankton does absorb carbon dioxide. It is furthermore believed that some of this carbon, locked away buy plankton, may actually make it to the ocean floor to be locked away long term at least in part. Indeed it is thought that carbon dioxide concentrations would be at least 50% higher wear it not for this part of the carbon cycle.

After the sudden rise in ivory poaching that started around 2008 there was a big increase in protection though this was often to slow. Half of the forest elephants of west Africa (thought to be as closely related to mammoths as African Savannah elephants), were taken in the last decade. ecosystems such as the Selous in Tanzania, one of the largest mostly undisturbed remaining Savannah habits, which lost up to 100,000 elephants.

News in brief – Otters in Peru, Adelie Penguins and Spring in the Arctic
Peru has set up a national park of 868,000 hectares that will protect the areas many animals and native people. This is one of the remaining areas of untouched Amazon within Peru. A recent survey saw showed that this area had a good population of giant otters. This is particularly exciting because, Continue reading “News in brief – Otters in Peru, Adelie Penguins and Spring in the Arctic”
UK extinct species and imported species – Part 2
Grey squirrels- invaders
These animals cause significant damage to woodland throughout the UK. They were first introduced to Henbury park in Cheshire, but have quickly spread. Being less reliant on trees than red squirrels they have done very well though it is thought that red squirrels were not doing well anyway. A great deal of money and time has been spent trying to control their spread, as they often carry squirrel pox which kills red squirrels quickly, meaning they don’t share land for long.

UK extinct species and imported species – Part 1
Huge numbers of species have been disappearing from some or all of their original range in the wild. While there are other reasons for animals to disappear from areas, humans are usually the biggest. This is certainly the case on a micro scale. The majority of impacts of climate change has shifted the entire range for a species in one direction or another. Many mountainous species have shifted their range up hill as the planet has warmed. The problem with this shifting is that often it leaves species stuck in small areas of suitable habitat at the top of hills or mountains.

The loss of wild dogs from the Serengeti – and their return
Image source Burrard-Lucas Photography
Before 1992, as well as the Lions and Cheetah, there were huge packs of African Wild Dog (also called African Hunting Dogs) that would follow the herds as well. This was one of the largest populations of African Wild Dog population so it was devastating to have the population wiped out so quickly. However, the land given to the nomadic people of the Serengeti

The Kob migration (South Sudan)
Image by Animal Picture Society
In 2011 a new country was created in Africa: South Sudan. This country is roughly the size of France. Before the split there had been a civil war going on much of the time for over 50 years. After the split there was a brief period of calm and scientists were able to go into the country to asses the state of the wildlife.
Astoundingly, despite the extraordinary length of fighting, among much wildlife, there existed a land migration Continue reading “The Kob migration (South Sudan)”
A second home for Asiatic Lions
The decline of the Asiatic lion occurred long before the decline of the African lion. Within the last 200 years lions were found across Asia into parts of eastern Europe. In ancient times they were even found in large parts of the Iberian peninsula, so from the furthest east of Asia to the furthest west of Europe.

West African Lions
There are a small number of lions that still live in West Africa. The population is in steep decline and is now only found reliably in one protected area with small remaining populations in a few others. The last significant population is found in a transboundary protected area between Niger Benin and Burkina Faso. This consists of Arli National park in South East Burkina Faso, Pendjari National Park in Benin and Singou Reserve. This group of protected areas is collectively called the WAP complex (W-Arli-Pendjari). Continue reading “West African Lions”
New species of Orangutan
The Tapamuli Orangutan has recently been discovered. There are only thought to be 800 of these animals left and they are only found within the Batang Toru Forest of North Sumatra. It is thought that they have been a separate from the Borneon Orangutan for 674,000 years (despite living on Sumatra they appear to be more closely related to the Orangutans of Borneo than of Sumatra). As well as having such a tiny population they also live in an area of roughly 1000 square kilometres (386 square miles). This is the first great ape species to be discovered since 1929 when the Bonobo was discovered.
