A severe drought gripping Texas is causing unusually salty conditions along the Gulf Coast, upsetting the region's ecological balance and threatening coastal wildlife including oysters, crabs and whooping cranes, the most endangered crane species.

The drought is one of the driest on record for Texas and is currently the worst in the U.S., which has seen persistent dry weather across several Western states, Florida and even Hawaii, according to academic and government monitors. The scarcity of rain has reduced fresh-water flow from rivers and streams into coastal marshes, estuaries and bays that normally dilute the salt content of water from the Gulf of Mexico.

This spring, the only migrating whooping-crane flock that exists in the wild lost 23 of its 270 members to hunger and disease brought on by the dry weather, said Tom Stehn, U.S. Fish and Wildlife Service whooping-crane coordinator.




Chromium: another threat to whale health?

Endangered sperm whales are highly polluted with the metal chromium, a known human carcinogen.

Researchers sampling skin from sperm whales around the world found the animals have the highest levels of the metal chromium in their bodies of any marine mammal tested to date. The levels in the skin of the whales are similar to those found in lung tissues of humans with chromium-induced lung cancer and may be an additional health threat to the already endangered species.

Little is known about chromium in the world's ocean despite its link to human cancers.
