An individual-based model of rabbit viral haemorrhagic disease on European wild rabbits (Oryctolagus cuniculus)
We developed an individual-based model of Rabbit Viral Hemorrhagic Disease (RVHD) for European wild rabbits (Oryctolagus cuniculus L.), representing up to 1000 rabbits in four hectares. Model output for productivity and recruitment matched published values. The disease was density-dependent and virulence affected outcome. Strains that caused death after several days produced greater overall mortal

Applying linear programming to estimate fluxes in ecosystems or food webs: An example from the herpetological assemblage of the freshwater Everglades
We present the application of Linear Programming for estimating biomass fluxes in ecosystem and food web models. We use the herpetological assemblage of the Everglades as an example. We developed food web structures for three common Everglades freshwater habitat types: marsh, prairie, and upland. We obtained a first estimate of the fluxes using field data, literature estimates, and professional ju

The importance of propagule establishment and physical factors in mangrove distributional patterns in a Costa Rican estuary
Establishment of Laguncularia racemosa, Avicennia germinans, and A. bicolor was measured along intertidal gradients (mud bank (MB), lower intertidal (LI), and upper intertidal (UI)) on point bars and islands in a Costa Rican tropical estuary. Successful establishment showed the following order — Laguncularia: LI (73%)>MB (52%)>UI (18%), with UI significantly lower than LI and MB; Avicennia spp.: L

Importance of the predator's ecological neighborhood in modeling predation on migrating prey
Most mathematical descriptions of predator-prey interactions fail to take into account the spatio-temporal structures of the populations, which can lead to errors or misinterpretations. For example, a compact pulse of prey migrating through a field of quasi-stationary predators may not be well described by standard predator-prey models, because the predators and prey are unlikely to be well mixed;

. Ecological conceptual models: a framework and case study on ecosystem management for South Florida sustainability
The Everglades and South Florida ecosystems are the focus of national and international attention because of their current degraded and threatened state. Ecological risk assessment, sustainability and ecosystem and adaptive management principles and processes are being used nationally as a decision and policy framework for a variety of types of ecological assessments. The intent of this study is t

The adventive status of Salvinia minima and S. molestain the southern United States and the related distribution of the weevil Cyrtobagous salviniae
The recent introduction of Salvinia molesta constitutes a serious threat to aquatic systems in the warm temperate regions of the United States. Salvinia minima, the only other member of Salviniaceae present in North America, is considered native by current floras. Evidence is presented which suggests that Salvinia minima was also introduced to North America, probably during the late 1920s and earl
