Spectral reflectance and canopy structure characteristics of gulf coast wetland vegetation types
Field measurements of canopy structure and species composition are related to spectral reflectance measurements taken with a radiometer over a number of marsh sites. Marsh vegetation types are discussed in terms of their characteristic canopy structure and phenology; the influence of these characteristics on spectral reflectance will be examined. Vegetation types that are discussed include Panicum

Marsh submergence vs. marsh accretion: Interpreting accretion deficit data in coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative sea-level rise are high in Louisiana due to high rates of subsidence. Although marsh accretion rates are also high, they are usually insufficient to maintain the relative elevation of the marsh surface. This situati

Proceedings of the symposium on restoration planning for the rivers of Mississippi River ecosystem
This volume presents over 25 papers containing the proceedings of a symposium held at the 122nd annual meeting of the American Fisheries Society in September 1992. The symposium was organised to review the status of fish and wildlife resources and restoration planning for the Mississippi river ecosystem. The objectives of the symposia were as follows: to present existing information of the biota a

Foraging ecology as related to the distribution of planktivorous auklets in the Bering Sea
We review recent accounts of the foraging ecologies of five species of small auklets found in the Bering Sea. These birds eat a wide variety of zooplankton and micronekton. Least Auklets Aethia pusilla and Whiskered Auklets A. pygmaea, as far as is known, primarily eat copepods, whereas Created Auklets A. cristatella appear to specialize on euphausiids, at least during the breeding season. The di
