Prey vulnerability to peacock cichlids and largemouth bass based on predator gape and prey body depth Prey vulnerability to peacock cichlids and largemouth bass based on predator gape and prey body depth
The interaction of prey fish body depth and predator gape size may produce prey assemblages dominated by invulnerable prey and excessive prey-to-predator biomass ratios. Peacock cichlids (Cichla ocellaris) were stocked into southeast Florida canals to consume excess prey fish biomass, particularly spotted tilapia (Tilapia mariae). The ecomorphologically similar largemouth bass...

Cryopreservation of sperm of red abalone (Haliotis rufescens) Cryopreservation of sperm of red abalone (Haliotis rufescens)
Abalone culture, a developing industry in Baja California, Mexico, would benefit from genetic improvement and controlled breeding. The use of cryopreserved sperm would allow germplasm availability, and this study was designed to develop sperm cryopreservation protocols for red abalone Haliotis rufescens. The acute toxic effects of the cryoprotectants dimethyl sulfoxide (DMSO), propylene...

Genetic effects of a large-scale Spartina alterniflora (smooth cordgrass) dieback and recovery in the northern Gulf of Mexico Genetic effects of a large-scale Spartina alterniflora (smooth cordgrass) dieback and recovery in the northern Gulf of Mexico
A large-scale dieback event struck marshes along the northwestern Gulf of Mexico coast during summer 2000, in apparent response to a prolonged and severe drought. Along the Louisiana coast, large areas of the dominant marsh species, Spartina alterniflora, turned brown, followed by death of at least the aboveground structures of entire plant mortality. Key ecological and genetic measures...

Estimating size and composition of biological communities by modeling the occurrence of species Estimating size and composition of biological communities by modeling the occurrence of species
We develop a model that uses repeated observations of a biological community to estimate the number and composition of species in the community. Estimators of community-level attributes are constructed from model-based estimators of occurrence of individual species that incorporate imperfect detection of individuals. Data from the North American Breeding Bird Survey are analyzed to...

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.

Light attenuation profiling as an indicator of structural changes in coastal marshes Light attenuation profiling as an indicator of structural changes in coastal marshes
To best respond to natural and human-induced stresses, resource managers and researchers require remote sensing techniques that can map the biophysical characteristics of natural resources on regional and local scales. The implementation of advanced measurement techniques would provide significant improvements in the quantity, quality, and timeliness of biophysical data useful in...
