Parasites and commensals of the West Indian manatee from Puerto Rico Parasites and commensals of the West Indian manatee from Puerto Rico
Metazoan parasites and commensals were collected from dead manatees salvaged in Puerto Rico. Thirty-five manatees were examined between 1980 and 1998. Parasites and commensals were identified in 20 (57%) manatees and included 3 species of helminths, 1 nematode (Heterocheilus tunicatus) and 2 digeneans (Chiorchis fabaceus and Cochleotrema cochleotrema). Two species of commensals were also

Management implications of fish trap effectiveness in adjacent coral reef and gorgonian habitats Management implications of fish trap effectiveness in adjacent coral reef and gorgonian habitats
A combination of visual census and trap sampling in St. John, USVI indicated that traps performed better in gorgonian habitat than in adjacent coral reef habitat. Although most families were seen more commonly in coral habitat, they were caught more often in gorgonian areas. Traps probably fished more effectively in gorgonian habitats, especially for migrating species, because traps...

Modeling the effects of nutria (Myocastor coypus) on wetland loss Modeling the effects of nutria (Myocastor coypus) on wetland loss
We created a model to study the process in which nutria (Myocastor coypus) feeding activities lead to erosion and loss of marsh area. This model ties together data on nutria population dynamics and feeding behavior from the literature with data from field studies on the phenology of Scirpus americanus and Spartina patens conducted in the Barataria Basin, Louisiana, USA in 1992. The...

Manatee response to boating activity in a thermal refuge Manatee response to boating activity in a thermal refuge
Thermal refuges are important for the endangered Florida manatee (Trichechus manatus latirostris) during winter cold periods in temperate latitudes. However, little research has examined impacts on manatees from human disturbance during these critical periods. We studied the effect of recreational boating activity on manatee use of established sanctuaries in the natural thermal refuge...

Relationships between hydraulic parameters in a small stream under varying flow and seasonal conditions Relationships between hydraulic parameters in a small stream under varying flow and seasonal conditions
Twenty conservative tracer injections were carried out in the same reach of a small woodland stream in order to determine how variation in discharge and leaf accumulation affect stream hydraulic parameters. The injections were made at various discharge rates ranging from 2-6 to 40 1/s. Five of the injections were made during late autumn, when there were large accumulations of leaves in...

Effects of spatial grouping on the functional response of predators Effects of spatial grouping on the functional response of predators
A unified mechanistic approach is given for the derivation of various forms of functional response in predator-prey models. The derivation is based on the principle-of-mass action but with the crucial refinement that the nature of the spatial distribution of predators and/or opportunities for predation are taken into account in an implicit way. If the predators are assumed to have a...
