The relationship between species richness and community biomass: The importance of environmental variables The relationship between species richness and community biomass: The importance of environmental variables
Several studies have used plant community biomass to predict species richness with varying success. In this study we examined the relationship between species richness and biomass for 36 marsh communities from two different watersheds. In addition, we measured several environmental variables and estimated the potential richness (the total number of species known to be able to occur in a...

Seagrasses, dredging and light in Laguna Madre, Texas, U.S.A. Seagrasses, dredging and light in Laguna Madre, Texas, U.S.A.
Light reduction resulting from maintenance dredging was the suspected cause of large-scale loss of seagrass cover in deep parts of Laguna Madre between surveys conducted in 1965 and 1974. Additional changes to 1988, together with an analysis of dredging frequency and intensity for different parts of the laguna, were consistent with this interpretation. Intensive monitoring of the...

Intraspecific variation in the response of Taxodium distichum seedlings to salinity Intraspecific variation in the response of Taxodium distichum seedlings to salinity
Seedlings of 15 open-pollinated families of baldcypress (Taxodium distichum) were tested for their tolerance to combined salinty and flooding stress. Ten of the families were from coastal locations in Louisiana or Alabama, USA, that were slightly brackish. The other families were from locations not affected by saltwater intrusion. Five salinity levels were investigated--0,2,4,6, and 8 g...

Use of saltwater and freshwater habitats by wintering redheads in southern Texas Use of saltwater and freshwater habitats by wintering redheads in southern Texas
Behavioral data were gathered for redheads (Aythya americana Eyton) using saltwater and freshwater habitats in southern Texas, the northern portion of their major wintering range, in 1989–90. Saltwater and freshwater habitats were used for different purposes by wintering redheads. Approximately 41% of all redheads in saltwater habitats were feeding, while only 0.1% of redheads in...

Environmental contaminants in redheads wintering in coastal Louisiana and Texas Environmental contaminants in redheads wintering in coastal Louisiana and Texas
Whole body and liver analyses indicated that wintering redheads (Aythya americana; n = 70) in coastal Louisiana (one site) and Texas (two sites) were relatively free of contamination with common trace elements, organochlorines, and hydrocarbons. Most trace elements, including As, Cr, Hg, Mg, Mn, Ni, Pb, Se, Sr, and Zn, were within background concentrations in livers; levels of B, Cd, Cu...
