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.

Equation-free modeling unravels the behavior of complex ecological systems
Ye et al. (1) address a critical problem confronting the management of natural ecosystems: How can we make forecasts of possible future changes in populations to help guide management actions? This problem is especially acute for marine and anadromous fisheries, where the large interannual fluctuations of populations, arising from complex nonlinear interactions among species and with varying envirAuthorsDonald L. DeAngelis, Simeon YurekA plant toxin mediated mechanism for the lag in snowshoe hare population recovery following cyclic declines
A necessary condition for a snowshoe hare population to cycle is reduced reproduction after the population declines. But the cause of a cyclic snowshoe hare population's reduced reproduction during the low phase of the cycle, when predator density collapses, is not completely understood. We propose that moderate-severe browsing by snowshoe hares upon preferred winter-foods could increase the toxicAuthorsDonald L. DeAngelis, John P. Bryant, Rongsong Liu, Stephen A. Gourley, Charles J Krebs, Paul B ReichardtModelling the effects of seasonality and socioeconomic impact on the transmission of Rift Valley fever virus
Rift Valley fever (RVF) is an important mosquito-borne viral zoonosis in Africa and the Middle East that causes human deaths and significant economic losses due to huge incidences of death and abortion among infected livestock. Outbreaks of RVF are sporadic and associated with both seasonal and socioeconomic effects. Here we propose an almost periodic three-patch model to investigate the transmissAuthorsYanyu Xiao, John C.

DeAngelis, Shigui RuanA spatial individual-based model predicting a great impact of copious sugar sources and resting sites on survival of Anopheles gambiae and malaria parasite transmission
BackgroundAgent-based modelling (ABM) has been used to simulate mosquito life cycles and to evaluate vector control applications. However, most models lack sugar-feeding and resting behaviours or are based on mathematical equations lacking individual level randomness and spatial components of mosquito life. Here, a spatial individual-based model (IBM) incorporating sugar-feeding and resting behaviAuthorsLin Zhu, Whitney A. Qualls, John M Marshall, Kris L. Arheart, Donald L. DeAngelis, John W.

BeierPredicting spatial and temporal distribution of Indo-Pacific lionfish (Pterois volitans) in Biscayne Bay through habitat suitability modeling
Invasive species may exhibit higher levels of growth and reproduction when environmental conditions are most suitable, and thus their effects on native fauna may be intensified. Understanding potential impacts of these species, especially in the nascent stages of a biological invasion, requires critical information concerning spatial and temporal distributions of habitat suitability. Using empiricAuthorsNicholas A. Bernal, Donald L. DeAngelis, Pamela J. Schofield, Kathleen Sullivan SealeyPopulation age and initial density in a patchy environment affect the occurrence of abrupt transitions in a birth-and-death model of Taylor's law
Taylor's power law describes an empirical relationship between the mean and variance of population densities in field data, in which the variance varies as a power, b, of the mean. Most studies report values of b varying between 1 and 2. However, Cohen (2014a) showed recently that smooth changes in environmental conditions in a model can lead to an abrupt, infinite change in b.

CohenAnalysis and simulation of propagule dispersal and salinity intrusion from storm surge on the movement of a marsh–mangrove ecotone in South Florida
Coastal mangrove–freshwater marsh ecotones of the Everglades represent transitions between marine salt-tolerant halophytic and freshwater salt-intolerant glycophytic communities. It is hypothesized here that a self-reinforcing feedback, termed a “vegetation switch,” between vegetation and soil salinity, helps maintain the sharp mangrove–marsh ecotone. A general theoretical implication of the switcAuthorsJiang Jiang, Donald L. DeAngelis, Gordon H. Anderson, Thomas J. SmithCan antibrowsing defense regulate the spread of woody vegetation in arctic tundra?
Global climate warming is projected to promote the increase of woody plants, especially shrubs, in arctic tundra. Many factors may affect the extent of this increase, including browsing by mammals. We hypothesize that across the Arctic the effect of browsing will vary because of regional variation in antibrowsing chemical defense. Using birch (Betula) as a case study, we propose that browsing is uAuthorsJohn P. Bryant, Kyle Joly, F. Stuart Chapin, Donald L.

1. Agent-based models (ABMs) are widely used to predict how populations respond to changing environments. As the availability of food varies in space and time, individuals should have their own energy budgets, but there is no consensus as to how these should be modelled. Here, we use knowledge of physiological ecology to identify major issues confronting the modeller and to make recommendations abAuthorsRichard M. Sibly, Volker Grimm, Benjamin T. Martin, Alice S.A.

Community ecology seeks to understand and predict the characteristics of communities that can develop under different environmental conditions, but most theory has been built on analytical models that are limited in the diversity of species traits that can be considered simultaneously.

An aim of community ecology is to understand the patterns of competing species assembly along environmental gradients. All species interact with their environments. However, theories of community assembly have seldom taken into account the effects of species that are able to engineer the environment. In this modeling study, we integrate the species' engineering trait together with processes of immAuthorsJiang Jiang, Donald L. DeAngelis - News
