Distribution and status of submerged vegetation in estuaries of the upper Texas coast Distribution and status of submerged vegetation in estuaries of the upper Texas coast

Composition and biomass of beds of submerged aquatic vegetation (SAV) in estuaries along the upper Texas coast were examined from bottom core and rake samples taken along 72 line transects during July–August 1987. Substrate composition, salinity, water depth, and water clarity were also measured at each sample station. Halodule wrightii was the dominant species of SAV meadows (69%...

Aquatic invertebrate production in southeastern USA wetlands during winter and spring Aquatic invertebrate production in southeastern USA wetlands during winter and spring

We measured aquatic invertebrate abundance, standing stock biomass, and community production in three types of wetlands on Noxubee National Wildlife Refuge from December 1987 through April 1988. Together, Orthocyclops modestus and Daphnia pulex were the most abundant organisms collected in all habitats during both winter and spring, but each contributed little to total standing stock...

Effects of weather and tides on feeding and flock positions of wintering redheads in the Chandeleur Sound, Louisiana Effects of weather and tides on feeding and flock positions of wintering redheads in the Chandeleur Sound, Louisiana

We studied the effects of weather and tides on percent feeding and flock positions of wintering redheads (Aythya americana Eyton) in the Chandeleur Sound, Louisiana, USA. Flock scans (n = 750) were made on 55 flocks from November through March of 1988–1989. The percent of the flock that was feeding was negatively correlated with time of day, temperature, water level, and distance of the...

Mangroves, hurricanes, and lightning strikes: Assessment of Hurricane Andrew suggests an interaction across two differing scales of disturbance Mangroves, hurricanes, and lightning strikes: Assessment of Hurricane Andrew suggests an interaction across two differing scales of disturbance

The track of Hurricane Andrew carried it across one of the most extensive mangrove for ests in the New World. Although it is well known that hurricanes affect mangrove forests, surprisingly little quantitative information exists concerning hurricane impact on forest structure, succession, species composition, and dynamics of mangrove-dependent fauna or on rates of eco-system recovery...

Hurricanes and anchors: preliminary results from the National Park Service regional reef assessment program Hurricanes and anchors: preliminary results from the National Park Service regional reef assessment program

The U .S . National Park Service NPS began a Regional Assessment Program for coral reefs in the U.S. Virgin Islands and Florida in 1988. Scientists from NPS and six other institutions have now established longterm monitoring sites at Virgin Islands National Park St. John, USVI, Buck Island Reef National Monument St. Croix, USVI, Biscayne National Park Florida and Fort Jefferson National...
