Sea Otters: Adorable, Endangered, and A Keystone Species
This cuddly creature is a sea otter, or Enhydra lutris, a well-known marine mammal native to the coasts of the northern and eastern North Pacific Ocean. This furry, playful fellow is more than j…
Infographic: Wolves Keep Yellowstone in the Balance
In the 1920s, government policy allowed the extermination of Yellowstone’s gray wolf -- the apex predator -- triggering an ecosystem collapse known as trophic cascade. In 1995 -- through use of the Endangered Species Act -- the conservation community reintroduced the gray wolf to restore balance. The impact was dramatic.
The Top 5 Keystone Species
As we all know this Earth we find ourselves on is fragile; all that we see in nature is just a series of delicately balanced interactions between species (including us). But sometimes certain species have a linchpin role in such balances. Here are the top 5 keystone species we owe our world to.

What Happens When a Keystone Species Goes Extinct?
Without its keystone, a Roman aqueduct collapses. Does the same travesty befall an ecosystem when a keystone species goes missing from the ecological equation?
Keystone Species: How Predators Create Abundance | MOTHER EARTH NEWS
Wolves returned to Glacier and Yellowstone National Parks in the 1980s and 90s, and the resulting ecosystem-balancing effect of their presence cements their role as keystone species.
Examples of Keystone Species
In an ecosystem, all living things rely on each other and work together to be healthy; but, some species are crucial to the way all the species interrelate. When a keystone species is removed from a habitat, the habitat is dramatically changed. All other species are affected and some may disappear from that ecosystem or even become extinct.
Destruction of Species – Researchers Discuss Biodiversity Crisis
Nature is becoming less diverse all across the globe, which is also threatening the future of humankind. Researchers emphasise the fact that there is still hope, but now is the time to act. Professors Kari Saikkonen and Ilari E. Sääksjärvi emphasise the need for protecting natural forests that are home to diverse species. In Finland, forests cover over 70% of the country’s surface area, but especially in the south most of it is commercial forest.
One main point of the talks is to emphasize that elephants are a "keystone species," meaning elephants are responsible for the well-being of other animals and plants in their ecosystem.
Rosie and Opal aren't just retired circus elephants: They're beacons of hope for their endangered species. Hope Elephants, located in aptly named Hope, Maine, is a nonprofit sanctuary devoted to the well-being and conservation of elephants worldwide.
Sea otters, kelp forests, and the extinction of Steller’s sea cow
Human-caused extinctions are normally thought to result from overexploitation or habitat alteration. A third possible cause of extinction is the loss of interactions associated with keystone species. Using recent and historical information on sea otters and kelp forests, we show that the extinction of Steller's sea cow from the Commander Islands in the mid-1700s would have been a nearly inevitable consequence of the overhunting of sea otters, which occurred a decade earlier.
Have You Hugged an Apex Predator Today?
Did you know that whale poop can slow climate change, wolves can change rivers, and the sand from China's Gobi Desert is now reaching the United States? It's all about those apex predators and keystone species!
