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.

The confluences of ideas leading to, and the flow of ideas emerging from, individual-based modeling of riverine fishes
In this review article, we trace the history of events leading to the development of individual-based models (IBMs) to represent aquatic organisms in rivers and streams. As a metaphor, we present this history as a series of confluences between individual scientists (tributaries) sharing ideas. We describe contributions of these models to science and management. One iconic feature of river IBMs isAuthorsHenriette I. Jager, Donald L. DeAngelisGrowth stress response to sea level rise in species with contrasting functional traits: A case study in tidal freshwater forested wetlands
With rising sea levels, mortality of glycophytes can be caused by water and nutrient stress under increasing salinity. However, the relative effects of these two stressors may vary by species-specific functional traits. For example, deciduous species, with leaves typically emerging during low salinity periods of the year, may suffer less from water stress than evergreen species. We sampled two wooAuthorsLu Zhai, Ken W. Krauss, Xin Liu, Jamie A. Duberstein, William H. Conner, Donald L.

The sampled relative abundances of species of a taxonomic group, whether birds, trees, or moths, in a natural community at a particular place vary in a way that suggests a consistent underlying pattern, referred to as the species abundance distribution (SAD). Preston [1] conjectured that the numbers of species, plotted as a histogram of logarithmic abundance classes called octaves, seemed to fit aAuthorsDonald L. DeAngelisA parasitism-mutualism-predation model consisting of crows, cuckoos and cats with stage-structure and maturation delays on crows and cuckoos
In this paper, a parasitism-mutualism-predation model is proposed to investigate the dynamics of multi-interactions among cuckoos, crows and cats with stage-structure and maturation time delays on cuckoos and crows. The crows permit the cuckoos to parasitize their nestlings (eggs) on the crow chicks (eggs). In return, the cuckoo nestlings produce a malodorous cloacal secretion to protect the crowAuthorsYantao Luo, Long Zhang, Zhidong Teng, Donald L. DeAngelisConservation and restoration of mangroves: Global status, perspectives, and prognosis
Mangrove forests provide critical services around the globe to both human populations and the ecosystems they occupy. However, losses of mangrove habitat of more than 50% have been recorded in some parts of the world, and these losses are largely attributable to human activities. The importance of mangroves and the threats to their persistence have long been recognized, leading to actions taken loAuthorsStephanie S. Romañach, Donald L. DeAngelis, Hock Lye Koh, Yuhong Li, Su Yean Teh, Raja Sulaiman Raja Barizan, Lu ZhaiModeling the compensatory response of an invasive tree to specialist insect herbivory
The severity of the effects of herbivory on plant fitness can be moderated by the ability of plants to compensate for biomass loss. Compensation is an important component of the ecological fitness in many plants, and has been shown to reduce the effects of pests on agricultural plant yields. It can also reduce the effectiveness of biocontrol through introduced herbivores in controlling weedy invasAuthorsBo Zhang, Xin Liu, Donald L. DeAngelis, Lu Zhai, Min B.

Mathematical Models of Plant-Herbivore Interactions addresses mathematical models in the study of practical questions in ecology, particularly factors that affect herbivory, including plant defense, herbivore natural enemies, and adaptive herbivory, as well as the effects of these on plant community dynamics. The result of extensive research on the use of mathematical modeling to investigate the eAuthorsZhilan Feng, Donald L. DeAngelisMoving forward in circles: Challenges and opportunities in modeling population cycles
Population cycling is a widespread phenomenon, observed across a multitude of taxa in both laboratory and natural conditions. Historically, the theory associated with population cycles was tightly linked to pairwise consumer–resource interactions and studied via deterministic models, but current empirical and theoretical research reveals a much richer basis for ecological cycles.

A large body of theory predicts that populations diffusing in heterogeneous environments reach higher total size than if non-diffusing, and, paradoxically, higher size than in a corresponding homogeneous environment. However, this theory and its assumptions have not been rigorously tested. Here, we extended previous theory to include exploitable resources, proving qualitatively novel results, whicAuthorsBo Zhang, Alex Kula, Keenan M.L. Mack, Lu Zhai, Arrix L.

Usually, the origin of a within-cohort bimodal size distribution is assumed to be caused by initial size differences or by one discrete period of accelerated growth for one part of the population. The aim of this study was to determine if more continuous pathways exist allowing shifts from the small to the large fraction within a bimodal age-cohort. Therefore, a Eurasian perch population, which haAuthorsLisa Heerman, Donald L. DeAngelis, Jost BorcherdingSimilarity of plant functional traits and aggregation pattern in a subtropical forest
The distribution of species and communities in relation to environmental heterogeneity is a central focus in ecology. Co-occurrence of species with similar functional traits is an indication that communities are determined in part by environmental filters. However, few studies have been designed to test how functional traits are selectively filtered by environmental conditions at local scales. ExpAuthorsBo Zhang, Xiaozhen Lu, Jiang Jiang, Donald L.

Blake (hereafter melaleuca) is an invasive tree from Australia that has spread over the freshwater ecosystems of southern Florida, displacing native vegetation, thus threatening native biodiversity.
