Primary production in an impounded baldcypress swamp (Taxodium distichum) at the northern limit of the range Primary production in an impounded baldcypress swamp (Taxodium distichum) at the northern limit of the range
The ability of baldcypress (Taxodium distichum)swamps to maintain themselves near the northern limit of their range depends on their levels of production, which is not only are response to climate but also to local environmental factors(e.g., impoundment). We asked if primary production was reduced under impounded conditions and if species' responses to impoundment were individualistic...

Improving removal-based estimates of abundance by sampling a population of spatially distinct subpopulations Improving removal-based estimates of abundance by sampling a population of spatially distinct subpopulations
A statistical modeling framework is described for estimating the abundances of spatially distinct subpopulations of animals surveyed using removal sampling. To illustrate this framework, hierarchical models are developed using the Poisson and negative-binomial distributions to model variation in abundance among subpopulations and using the beta distribution to model variation in capture

Mismatch between herbivore behavior and demographics contributes to scale-dependence of host susceptibility in two pine species Mismatch between herbivore behavior and demographics contributes to scale-dependence of host susceptibility in two pine species
The impacts on forests of tree-killing bark beetles can depend on the species composition of potential host trees. Host susceptibility might be an intrinsic property of tree species, or it might depend on spatial patterning of alternative host species. We compared the susceptibility of loblolly pine (Pinus taeda) and Virginia pine (P. virginiana) to southern pine beetle (Dendroctonus...

Implications of global climatic change and energy cost and availability for the restoration of the Mississippi delta Implications of global climatic change and energy cost and availability for the restoration of the Mississippi delta
Over the past several thousand years, inputs from the Mississippi River formed the Mississippi delta, an area of about 25,000 km2. Over the past century, however, there has been a high loss of coastal wetlands of about 4800 km2. The main causes of this loss are the near complete isolation of the river from the delta, mostly due to the construction of flood control levees, and pervasive

Depicting coastal Louisiana land loss Depicting coastal Louisiana land loss
The Coastal Louisiana Land Loss map depicts historical (1932-2000) changes of land to water and water to land, as well as projected changes (2000-2050). Projections are based on the assumption of no future restoration.

Changes in the fish fauna of the Kissimmee River basin, peninsular Florida: Nonnative additions Changes in the fish fauna of the Kissimmee River basin, peninsular Florida: Nonnative additions
Recent decades have seen substantial changes in fish assemblages in rivers of peninsular Florida. The most striking change has involved the addition of nonnative fishes, including taxa from Asia, Africa, and Central and South America. I review recent and historical records of fishes occurring in the Kissimmee River basin (7,800 km2), a low-gradient drainage with 47 extant native fishes...

Quantitative assessment of benthic food resources for juvenile Gulf sturgeon, Acipenser oxyrinchus desotoi in the Suwannee River estuary, Florida, USA Quantitative assessment of benthic food resources for juvenile Gulf sturgeon, Acipenser oxyrinchus desotoi in the Suwannee River estuary, Florida, USA
Gulf sturgeon, Acipenser oxyrinchus desotoi, forage extensively in the Suwannee River estuary following emigration out of the Suwannee River, Florida. While in the estuary, juvenile Gulf sturgeon primarily feed on benthic infauna. In June–July 2002 and February–April 2003, random sites within the estuary were sampled for benthic macrofauna (2002 n = 156; 2003 n = 103). A mean abundance...

Timing of seed dispersal generates a bimodal seed bank depth distribution Timing of seed dispersal generates a bimodal seed bank depth distribution
The density of soil seed banks is normally highest at the soil surface and declines monotonically with depth. Sometimes, for a variety of reasons, peak density occurs below the surface but, except in severely disturbed soils, it is generally true that deeper seeds are older. In seasonally dry habitats that develop deep soil cracks during the dry season, it is possible that some seeds...
