Don DeAngelis is a Senior Scientist and Research Ecologist at the USGS Wetland and Aquatic Research Center.
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.

In praise of mechanistically-rich models
Quantitative models are crucial to almost every area of ecosystem science. They provide a logical structure that guides and informs empirical observations of ecosystem processes. They play a particularly crucial role in synthesizing and integrating our understanding of the immense diversity of ecosystem structure and function. Increasingly, models are being called on to predict the effects of humaAuthorsDonald L. DeAngelis, Wolf M. MooijThe importance of spatial scale in the modeling of aquatic ecosystems: Chapter 24

Temperature variation is an important factor in Everglade wetlands ecology. A temperature fluctuation from 17°C to 32°C recorded in the Everglades may have significant impact on fish dynamics. The short life cycles of some of Everglade fishes has rendered this temperature variation to have even more impacts on the ecosystem.

DeAngelis, Hooi-Ling LeeCarbon isotope composition of ambient CO2 and recycling: a matrix simulation model
The relationship between isotopic composition and concentration of ambient CO2 in a canopy and its associated convective boundary layer was modeled. The model divides the canopy and convective boundary layer into several layers. Photosynthesis, respiration, and exchange between each layer can be simulated by matrix equations. This simulation can be used to calculate recycling; defined here as theAuthorsLeonel da Silveira Lobo Sternberg, Donald L. DeAngelisEcological and evolutionary conditions for fruit abortion to regulate pollinating seed-eaters and increase plant production
Coevolved mutualisms, such as those between senita cacti, yuccas, and their respective obligate pollinators, benefit both species involved in the interaction. However, in these pollination mutualisms the pollinator's larvae impose a cost on plants through consumption of developing seeds and fruit. The effects of pollinators on benefits and costs are expected to vary with the abundance of pollinatoAuthorsJ. Nathaniel Holland, Donald L. DeAngelisExploring the effect of drought extent and interval on the Florida snail kite: Interplay between spatial and temporal scales
The paper aims at exploring the viability of the Florida snail kite population under various drought regimes in its wetland habitat. The population dynamics of snail kites are strongly linked with the hydrology of the system due to the dependence of this bird species on one exclusive prey species, the apple snail, which is negatively affected by a drying out of habitat. Based on empirical evidenceAuthorsWolf M. Mooij, Robert E. Bennetts, Wiley M. Kitchens, Donald L. DeAngelisPopulation dynamics and mutualism: Functional responses of benefits and costs
We develop an approach for studying population dynamics resulting from mutualism by employing functional responses based on density‐dependent benefits and costs. These functional responses express how the population growth rate of a mutualist is modified by the density of its partner. We present several possible dependencies of gross benefits and costs, and hence net effects, to a mutualist as funAuthorsJ. Nathaniel Holland, Donald L. DeAngelis, Judith L. BronsteinStructural instability, multiple stable states, and hysteresis in periphyton driven by phosphorus enrichment in the Everglades
Periphyton is a key component of the Everglades ecosystems. It is a major primary producer, providing food and habitat for a variety of organisms, contributing material to the surface soil, and regulating water chemistry. Periphyton is sensitive to the phosphorus (P) supply and P enrichment has caused dramatic changes in the native Everglades periphyton assemblages. Periphyton also affects P availAuthorsQuan Dong, Paul V. McCormick, Fred H. Sklar, Donald L. DeAngelisSIMSPAR Model Simulates the Impact of Hydrology on the Cape Sable Seaside Sparrow
