This bird is an endangered species in Norway, with numbers plummeting from around 160,000 pairs in the 1960s to just 15,000 breeding pairs today.
Mortality was found to rise in the winter months between November and March, which coincides with a greater congregation of dugongs and an increase in the level of fishing activity.
An international team of wildlife ecologists, led by Oregon State University, conducted a comprehensive analysis of data on the world’s largest herbivores
An international team of biologists recently scoured reports and research going back 250 years to identify nine ways humans pose a threat to penguins.
As recently as the 1960s the total population was in the thousands, so the species is now listed as critically endangered.
Chimpanzees are under threat from many human activities there are only around 6,000 individuals of the Nigerian-Cameroon chimpanzee subspecies are left in the wild.
The report states that wildlife populations today are 52% less than they were in 1970. In other words, in less than two generations, these populations have declined by more than half.
Their presence in such huge numbers has led scientists to try to discover the impact of this invasive species on the natural ecosystem and native species living in the park.
In all regions across the continent, there is no single cause of the decline, however, they do all appear to be linked by rising temperatures caused by climate change.
Like many other baleen whales, blue whales accumulate layers of wax, lipids and keratin protein in their ear canals, which build up over time to form long earplugs.
