Keystone species are those that help maintain the balance and survival of an ecosystem; without them, the ecosystem would drastically change, or it would completely disappear. As the name implies, these species are the keystone the ecosystem is based on; they are particularly important because, if they disappear, no other species can replace them. Keystone species are usually predators, but they might also include fungi and plants.

For more than 180 years, scientists have studied this rich ecosystem and its species. Among all the scientists, the Galapagos Islands were of great importance to Charles Darwin; it was the place that gave him the main idea of evolution by natural selection.

If you are an adventurer and a nature lover, you have to add the Galapagos Islands to your bucket list. In addition to the lack of natural predators and friendly wildlife, these Islands are teeming with a diverse array of endemic plants and animals. This means that they are not found elsewhere in the world, thanks to the geographical isolation of the Islands from other places.

There are some living organisms that cannot breathe the same way that mammals do because they do not have lungs, such as fish. If fish have a respiratory system similar to that of mammals, a single breath underwater will fill its lungs with fluids, making them useless.

Birds are on the move as annual migration is an integral part of the avian life-cycle. They fly tens of thousands of kilometers in search for more convenient ecological conditions, safer habitats, food, and mating grounds. 

Our ecosystems consist of armies of creatures; without their presence the whole ecosystem will collapse.

It has always been understood that life under ice takes the winter season off, but studies have found that life under the ice is very much active.

While big animals have big muscles, with smaller bodies, tiny creatures invest most of their muscle power in weightlifting.

Humans are taking Earth for granted to face the biggest environmental challenge our species has ever encountered; that is global warming.

While we know that the amount of threatened biodiversity is aplenty, there are some success stories that give us hope and serve as a real evidence of what protecting biodiversity actually looks like.

The great diversity of the Red Sea is not limited only to its wide variety of fishes, but there are plenty of other distinctive sea creatures.

Egypt’s Red Sea remains calm and peaceful season after season, but underneath its surface a world full of motion and life that dances all around.

Welcome to the "Land of Death" in the Bahariya Oasis; the most dangerous place during the Cretaceous period!

The loss of natural habitats is the main threat to 85% of all species listed on the International Union for Conservation of Nature (IUCN) Red List—a comprehensive information source on the extinction risk of animals, fungi, and plants.
