RESEARCH
Donald DeAngelis is an ecologist, specializing in mathematical and simulation modeling. He was one of the early developers of individual-based modeling (IBM) in population ecology, and has applied IBM to fish and other populations. Among his other interests are modeling of vegetation succession, nutrient cycling, mutualistic interactions, and food webs. He is coordinator of the Across Trophic Level System Simulation (ATLSS) Program, a multi-project, multi-investigator program with the objective of providing simulation models to assist Everglades restoration.

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 rare speciesAuthorsJ.H. Petersen, D.L. DeAngelis, C.P. PaukertA 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 vadose zone miAuthorsS.Y.

The model presented here modifies a susceptible-infected (SI) host-pathogen model to determine the influence of mating system on the outcome of a host-pathogen interaction. Both deterministic and stochastic (individual-based) versions of the model were used. This model considers the potential consequences of varying mating systems on the rate of spread of both the pathogen and resistance alleles wAuthorsD.L. DeAngelis, Jennifer M. Koslow, J. Jiang, S. RuanAllowing macroalgae growth forms to emerge: Use of an agent-based model to understand the growth and spread of macroalgae in Florida coral reefs, with emphasis on Halimeda tuna
The growth patterns of macroalgae in three-dimensional space can provide important information regarding the environments in which they live, and insights into changes that may occur when those environments change due to anthropogenic and/or natural causes. To decipher these patterns and their attendant mechanisms and influencing factors, a spatially explicit model has been developed. The model SPAuthorsA.T. Yniguez, J.W. McManus, D.L. DeAngelisFood web dynamics in a seasonally varying wetland
A spatially explicit model is developed to simulate the small fish community and its underlying food web, in the freshwater marshes of the Everglades. The community is simplified to a few small fish species feeding on periphyton and invertebrates. Other compartments are detritus, crayfish, and a piscivorous fish species. This unit food web model is applied to each of the 10,000 spatial cells on aAuthorsD.L. DeAngelis, J.C. Trexler, D.D.

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 analyzed to detAuthorsBrenda Rashleigh, D.L. DeAngelisCompetition 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 status sugAuthorsL.D.S.L. Sternberg, S.Y. Teh, S.M.L. Ewe, F. Miralles-Wilhelm, D.L. DeAngelisExploring 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 negative effect oAuthorsWolf M. Mooij, Julien Martin, Wiley M. Kitchens, Donald L. DeAngelisA standard protocol for describing individual-based and agent-based models
Simulation models that describe autonomous individual organisms (individual based models, IBM) or agents (agent-based models, ABM) have become a widely used tool, not only in ecology, but also in many other disciplines dealing with complex systems made up of autonomous entities. However, there is no standard protocol for describing such simulation models, which can make them difficult to understanAuthorsVolker Grimm, Uta Berger, Finn Bastiansen, Sigrunn Eliassen, Vincent Ginot, Jarl Giske, John Goss-Custard, Tamara Grand, Simone K.

Bascompte et al. (Reports, 21 April 2006, p. 431) used network asymmetries to explain mathematical conditions necessary for stability in historic models of mutualism. The Lotka-Volterra equations they used artificially created conditions in which some factor, such as asymmetric interaction strengths, is necessary for community coexistence. We show that a more realistic model incorporating nonlineaAuthorsJ. Nathaniel Holland, Toshinori Okuyama, Donald L. DeAngelis - News
