The agent-based model developed for the study considered three types of agents: invasive species, importers, and border enforcement agents. In the model, the invasive species can only react to their surroundings, while the importers and border enforcement agents are able to make their own decisions based on their own goals and objectives.
EwE has three main components: Ecopath – a static, mass-balanced snapshot of the system [2]; Ecosim – a time dynamic simulation module for policy exploration [3]; Ecospace – a spatial and temporal dynamic module designed for exploring the combined impacts of fishing, the placement of protected areas, [4] and changing environmental conditions.
An invasive species is an introduced species that harms its new environment. [2] Invasive species adversely affect habitats and bioregions, causing ecological, ...
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
The enemy release hypothesis is among the most widely proposed explanations for the dominance of exotic invasive species. In its native range, a species has co-evolved with pathogens, parasites and predators that limit its population. When it arrives in a new territory, it leaves these old enemies behind, while those in its introduced range are ...
The team of 86 researchers from 49 countries released a four-year assessment of the global impacts of some 3,500 harmful invasive species, finding that economic costs now total at least $423 ...
The Global Invasive Species Database is a database of invasive species around the world [1] run by the Invasive Species Specialist Group (ISSG) of the International Union for Conservation of Nature. [2] It publishes the list 100 of the World's Worst Invasive Alien Species. [3]
These are lists of invasive species by country or region. A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
