Population Genetics and Emergency Management of Two Kauai Island Endangered Species

The Challenge: The Akeke’e (Loxops caeruleirostris) and the Akikiki (Oreomystis bairdi), two species of Hawaiian honeycreeper, are critically endangered bird species endemic to high elevation ohia forests on the Hawaiian island of Kauai.  Both species have suffered severe population declines and range contractions in recent decades.  Akeke’e are currently thought to number ca. 950 wild...

Identifying the Genetic Basis of Avian Susceptibility to Mercury

The Challenge: Mercury is a highly toxic element found throughout our environment. Although it occurs naturally in some environments, human industrial pollution has greatly increased the amount of mercury and the range of environments in which mercury is found. Recent studies have confirmed clear differences in the sensitivity of various bird species to methylmercury. Because the causes of...

Effects of Short Chain Chlorinated Paraffins (SCCPs) on developing birds

The Challenge: Short-Chain Chlorinated Paraffins (SCCPs) are complex technical mixtures of polychlorinated n-alkanes used in lubricants and coolants in metalworking, as flame retardants, and in paints, adhesives, sealants, textiles and polymeric materials, plastics and rubber. SCCPs are of concern because they are globally transported, bioaccumulate in wildlife and humans, and are...

A Native Earthworm Accumulates Extraordinarily High Concentrations of Lead

The Challenge: As a rule, plants and animals contain lower concentrations of lead than are present in soils that support them. Lead does not biomagnify along trophic levels in ecosystems but instead remains relatively immobile in soil. The exposure of wildlife to soil lead depends mainly on the incidental ingestion of soil. The native earthworm, Eisenoides lonnbergi, is anomalous in its...

USGS News Release: Oldest Large Body of Ancient Seawater Identified under Chesapeake Bay

USGS scientists have determined that high-salinity groundwater found more than 1,000 meters (0.6 mi.) deep under the Chesapeake Bay is actually remnant water from the Early Cretaceous North Atlantic Sea and is probably 100-145 million years old. This is the oldest sizeable body of seawater to be identified worldwide.

Twice as salty as modern seawater, the ancient seawater was preserved...

Digital representation of exposures of Precambrian bedrock in parts of Dickinson and Iron Counties, Michigan, and Florence and Marinette Counties, Wisconsin

The U.S. Geological Survey (USGS) conducted a program of bedrock geologic mapping in much of the central and western Upper Peninsula of Michigan from the 1940s until the late 1990s. Geologic studies in this region are hampered by a scarcity of bedrock exposures because of a nearly continuous blanket of unconsolidated sediments resulting from...
