Dispersal of Brown Pelicans from a Natal Site in Bay County, Florida, with an Update on Brown Pelican Status in Florida

From 1982 through 1994, 1,086 brown pelican (Pelecanus occidentalis) pre-fledglings were banded with U.S. Fish and Wildlife Service aluminum bands in a spoil island nesting colony in St. Andrews Bay, Bay County, Florida. The colony was newly established the year banding was initiated and at the time constituted the only nesting colony on the Florida panhandle Gulf coast, with the nearest colonies being 250 km to the west in Louisiana and 165 km to the east near Cedar Key, Levy County, Florida. Excluding band recoveries from birds < 1 year old (N = 24) from the immediate vicinity of the...

Chironomid Communities as Indicators of Water Quality Affected by Acid Mine Drainage

Water and benthic samples were collected quarterly, May 1980 to May 1981, from 21 sedimentation ponds on the Ollis Creek strip mine in Campbell County, Tennessee. Water samples in general were low in pH and high in sulfate, hardness, iron, and manganese. A total of 63 discernable chironomid taxa was collected and identified. Low pH ponds were generally dominated by Chironomus attenuatus and Tanytarsus, while higher pH ponds contained variable chironomid assemblages. Diversity values (richness) were significantly correlated with pH values. The polar ordination of chironomid assemblages...
