(05/06/2013) Ordinarily, invasive and exotic species are a grave threat to native wildlife: outcompeting local species, introducing parasites and disease, and disturbing local ecological regimes. A unique case in the Brazilian Pantanal, however, has turned the tables; here, an introduced mammal has actually aided the conservation of native wildlife.
Up for grabs: how foreign investments are redistributing land and water across the globe
(04/18/2013) In 2007, the increased human population, increased prices in fuel and transportation costs, and an increased demand for a diversity of food products prompted a Global Food Crisis.

But the crisis had impacts beyond 2007: it was also the impetus for what we now know as the global land-grabbing phenomenon.
Asiatic cheetahs: on the road to extinction?
(02/26/2013) Cheetahs (Acinonyx jubatus) are unique among large cats. They have a highly specialized body, a mild temperament, and are the fastest living animals on land. Acinonyx jubatus venaticus, the Asiatic subspecies, is unique among cheetahs and the only member of five currently living subspecies to occur outside of Africa. Listed as Critically Endangered on the IUCN Red List—with a population of between 70 and 100 individuals—the Asiatic cheetah is one of the rarest felines on the planet. But new proposed road through one of its last habitat strongholds may threaten the cat even further.

(12/10/2012) The western scrub jay (Aphelocoma californica) is a common denizen of suburban neighborhoods in the U.S., loitering at bird feeders and amusing bird watchers with their entertaining antics. Known to birders as 'WESJ,' this handsome bird is non-migratory and territorial during the breeding season, but what's curious about WESJ's is the way they respond to risks in their environment. When descended on by a predator or encountering a dead member of its kind, these birds hop from perch to perch and call loudly, ensuing in a 'cacophonous reaction,' a term coined by researchers at the University of California, Davis who are studying the behavior of these unique birds.

Sacrificial squid has unique way of deterring predators
(09/04/2012) Octopoteuthis deletron—this deep-dwelling, unassuming little squid may appear plain and boring, but when threatened, it has a peculiar way of defending itself. This foot-long invertebrate behaves a bit differently than most of its close cousins: it drops its arms.
