A simulation model for projecting changes in salinity concentrations and species dominance in the coastal margin habitats of the Everglades A simulation model for projecting changes in salinity concentrations and species dominance in the coastal margin habitats of the Everglades
Sharp boundaries typically separate the salinity tolerant mangroves from the salinity intolerant hardwood hammock species, which occupy the similar geographical areas of southern Florida. Evidence of strong feedback between tree community-type and the salinity of the unsaturated (vadose) zone of the soil suggests that a severe disturbance that significantly tilts the salinity in the...

An overview of methods for developing bioenergetic and life history models for rare and endangered species An overview of methods for developing bioenergetic and life history models for rare and endangered species
Many fish species are at risk to some degree, and conservation efforts are planned or underway to preserve sensitive populations. For many imperiled species, models could serve as useful tools for researchers and managers as they seek to understand individual growth, quantify predator-prey dynamics, and identify critical sources of mortality. Development and application of models for...

Conditions for coexistence of freshwater mussel species via partitioning of fish host resources Conditions for coexistence of freshwater mussel species via partitioning of fish host resources
Riverine freshwater mussel species can be found in highly diverse communities where many similar species coexist. Mussel species potentially compete for food and space as adults, and for fish host resources during the larval (glochidial) stage. Resource partitioning at the larval stage may promote coexistence. A model of resource utilization was developed for two mussel species and...

Competition between hardwood hammocks and mangroves Competition between hardwood hammocks and mangroves
The boundaries between mangroves and freshwater hammocks in coastal ecotones of South Florida are sharp. Further, previous studies indicate that there is a discontinuity in plant predawn water potentials, with woody plants either showing predawn water potentials reflecting exposure to saline water or exposure to freshwater. This abrupt concurrent change in community type and plant water...

Exploring the temporal effects of seasonal water availability on the snail kite of Florida: Part III Exploring the temporal effects of seasonal water availability on the snail kite of Florida: Part III
The Florida snail kite (Rostrhamus sociabilis) is an endangered raptor that occurs as an isolated population, currently of about 2,000 birds, in the wetlands of southern and central Florida, USA. Its exclusive prey species, the apple snail (Pomacea paludosa) is strongly influenced by seasonal changes in water abundance. Droughts during the snail kite breeding season have a direct...
