The desert is a place of wide variety and vast array of life. Many plants and animals have adapted to the specific challenges for survival in the desert ecosystem. Desert animals have adaptations including special coloring, structures and behaviors, and desert plants have developed ways to collect...

Not many organisms can survive in this severe environment, the Sahara Desert, where daytime temperatures can reach 140 degrees Fahrenheit. But an insect called the Saharan silver ant grows well. They rush out onto the sand from their protected nests to gather up the bodies of insects that have...
In addition, water also transports leaf litter and other decaying vegetation and animal matter. The sediments and organic matter together contribute to the cycling of life-sustaining nutrients. The habitats of flora and fauna along the course of a river depend, in very complex ways, on the ...

Rock weathering is a key process in global elemental cycling. Life participates in this process with tangible consequences observed from the mineral interface to the planetary scale. Multiple lines of evidence show that microorganisms may play a pivotal—yet overlooked—role in weathering. This topic ...
For example, the microorganism Ferroplasma acidiphilum needs a large amount of iron to survive, quantities that would kill most other life forms. Like other extremophiles, F. acidiphilum may recall an ancient time on Earth when most organisms lived in harsh conditions similar to those ...

“I’ve heard everything between 1500 to 3000 years as an age estimate for the largestwelwitschias,” says Sussman about these strange plants. She photographed this example – probably around 2000 years old – in the Naukluft desert in Namibia. ...
different from their non-engineered cousins. These DNA signatures can be used as markers to quickly spot an engineered organism in a population of naturally occurring microorganisms. Young's role in the research project is to generate examples of bioengineered organisms that contain these specific ...
