Accounting for uncertainty in risk assessment: Case study of Hector's dolphin mortality due to gillnet entanglement

Article Abstract:

A case study on Hector's dolphin mortality due to gillnet entanglement highlights the uncertainties about biological data as well as human effects on ecosystem, which delay decisions on management of endangered species. A method incorporating uncertainty into the estimate of risk is developed to reduce the delays in action. It removes uncertainty in the scientific data as an excuse for inaction.

Forecasting biological invasions with increasing international trade

Article Abstract:

Historical data is used to parameterize species-accumulation models relating international trade to the establishment rates of nonindigenous species in the United States over the past century. Log-log and log-linear species-area models and Michaelis-Menten accumulation functions describe the relationships between the accumulation of non-native species and merchandise imports.

Evaluating dispersal estimates using mtDNA data: Comparing analytical and simulation approaches

Article Abstract:

Simulation models are designed to evaluate the adequacy of using analytical formulae to estimate dispersal rates needed for conservation decisions with mtDNA as a genetic marker. The model incorporates uncertainties into a probability distribution.
