About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

US cave system’s bats and insects face existential threat: discarded Cheetos (www.theguardian.com)

A full bag of Cheetos, discarded by a subterranean visitor to the Big Room in Carlsbad Caverns national park in New Mexico, has led the US National Park Service to issue a warning that discarded food could have a “huge impact” on the cave’s delicate and at-risk ecosystem.

“At the scale of human perspective, a spilled snack bag may seem trivial, but to the life of the cave it can be world changing,” the park said in its post about the garbage that was recently discovered there, threatening the balance of the unique cave system environment.

“The processed corn, softened by the humidity of the cave, formed the perfect environment to host microbial life and fungi,” officials wrote. “Cave crickets, mites, spiders and flies soon organize into a temporary food web, dispersing the nutrients to the surrounding cave and formations. Molds spread higher up the nearby surfaces, fruit, die and stink. And the cycle continues.”
