Behavioral profiles of the captive juvenile whooping crane (Grus americana) as an indicator of reintroduction behavior and survival Behavioral profiles of the captive juvenile whooping crane (Grus americana) as an indicator of reintroduction behavior and survival

Predation by bobcats (Lynx rufus) has been the greatest cause of mortality of whooping cranes (Grus americana) in the reintroduced population in Florida. This study investigated whether the behavior of juvenile cranes during captive rearing and shortly after release can be used to predict their chances of survival once released in the wild. This study also examined differences in...

Oral biology and beak disorders of birds Oral biology and beak disorders of birds

The beak, or bill, of the bird is a complicated structure. The avian skull is described as having some reptilian features; this includes a quadrate bone that articulates with the articular bone of the lower jaw.

A review of the role of contaminants in amphibian declines A review of the role of contaminants in amphibian declines

For the past decade, there has been growing concern about worldwide declines in amphibian populations,1,2 and a general phenomenon of declining populations was recognized in the mid-1990's. Subsequent research has validated this concern.3,4 These population declines have been defined either as decreases in numbers of individuals in an area or, preferably because of greater reliability, a...

The Chernobyl Nuclear Power Plant accident: ecotoxicological update The Chernobyl Nuclear Power Plant accident: ecotoxicological update

The accident at the Chernobyl, Ukraine, nuclear reactor on 26 April 1986 released large amounts of radiocesium and other radionuclides into the environment, contaminating much of the northern hemisphere, especially Europe. In the vicinity of Chernobyl, at least 30 people died, more than 115,000 others were evacuated, and consumption of milk and other foods was banned because of...

Biorecovery of gold Biorecovery of gold

Recovery of ionic and metallic gold (Au) from a wide variety of solutions by selected species of bacteria, yeasts, fungi, algae, and higher plants is documented. Gold accumulations were up to 7.0 g/kg dry weight (DW) in various species of bacteria, 25.0 g/kg DW in freshwater algae, 84.0 g/kg DW in peat, and 100.0 g/kg DW in dried fungus mixed with keratinous material. Mechanisms of...

Mineral resource of the month: silicon Mineral resource of the month: silicon

In the industrialized world, silicon is as ubiquitous in the objects people use every day as it is in nature. The second most abundant element in Earth’s crust and more than 25 percent of the crust by weight, silicon is one of the most useful elements to humans.

Streamflow and water-quality characteristics of the Ottawa River and selected tributaries in Allen, Hardin, and Putnam counties, Ohio Streamflow and water-quality characteristics of the Ottawa River and selected tributaries in Allen, Hardin, and Putnam counties, Ohio

Streamflow and water-quality measurements were made on the Ottawa River and selected tributaries between 1999 to 2002. Ten sets of streamflow measurements were made at an index station on the Auglaize River at Fort Jennings (station 04186500) and at 19 other sites along the Ottawa River and selected tributaries. These data were collected to relate daily mean streamflow at the Auglaize...

Use of sand wave habitats by silver hake Use of sand wave habitats by silver hake

Silver hake Merluccius bilinearis are common members of fish communities in sand wave habitats on Georges Bank and on Stellwagen Bank in the Gulf of Maine. Observations of fish size v. sand wave period showed that silver hake are not randomly distributed within sand wave landscapes. Regression analyses showed a significant positive relationship between sand wave period and fish length...

Tidal truncation and barotropic convergence in a channel network tidally driven from opposing entrances Tidal truncation and barotropic convergence in a channel network tidally driven from opposing entrances

Residual circulation patterns in a channel network that is tidally driven from entrances on opposite sides are controlled by the temporal phasing and spatial asymmetry of the two forcing tides. The Napa/Sonoma Marsh Complex in San Francisco Bay, CA, is such a system. A sill on the west entrance to the system prevents a complete tidal range at spring tides that results in tidal truncation...

Winter-time circulation and sediment transport in the Hudson Shelf Valley Winter-time circulation and sediment transport in the Hudson Shelf Valley

The Hudson Shelf Valley is a bathymetric low that extends across the continental shelf offshore of New York and New Jersey. From December 1999 to April 2000 a field experiment was carried out to investigate the transport of sediment in the shelf and valley system. Near-bed tripods and water-column moorings were deployed at water depths from 38 to 75 m in the axis of the shelf valley and...
