Species that are exotic and cause significant economic or ecological damage.

Species introduced to an area where they are not native.

Human activities that assist the spread of invasive species.

Using natural enemies to regulate pest populations.

Unintentional introduction of species through various means.

Mechanisms of organism transport to new habitats.

Routes taken by species from source to novel habitat.

Movements by individuals beyond their current range without human aid.

Processes like wind, water, and animal migration that disperse species naturally.

Dispersal of species influenced by human activities, often introducing them in large numbers.

Alteration of ecosystems, often caused by invasive species introduced through human activities.

A framework explaining species richness based on immigration and extinction rates in isolated places.

The process of new species arriving in a habitat, adding to species richness.

The process of species disappearing from a habitat, subtracting from species richness.

Deliberate movement of organisms to new areas for specific purposes like crops or pets.

Accidental movement of organisms due to human activities or travel.

Air trade affects the arrival of organisms based on climate similarity and traffic periods.

A transport model where hubs have high invasion likelihood, but spread is variable.

Nutria, introduced in Louisiana, has significant negative ecological impact due to high reproduction.

The probability of an invasive species passing through four stages: 1 in 10.

Invasion success varies by taxon and geography; plants succeed better than vertebrates.

Newly sampled areas often show existing species before new ones are found.

Changes in transport methods affect species introduction trends over time.

Dredging at Pearl Harbor in the early 1900s opened up new species transport routes.

The rate at which new species are identified as sampling increases, but decelerates due to repeats.

A lagged increase in invasive species due to previous trade booms.

Characteristic of a habitat's susceptibility to invasion by exotic species.

E = I x S; explains the number of exotic species based on introductions and survival rates.

Patterns showing more invasive species on islands compared to mainland.

To test for invasibility, one must account for the number of introductions.

GDP often serves as a proxy for the volume of trade and its impacts on species introduction.

Delays in changes of vector strength can lead to delayed exotic species introductions.

Purposeful introductions of non-native species, often for biofuel, ornamental, or enhancement.

Crops bred for low maintenance and high productivity used as renewable fuel sources.

Trade involving the shipment of live animals, often leading to accidental introductions.

Introduction of species to control pests; past involved vertebrates, now focuses on insects.

Institutions that provide education and conservation but may introduce non-native species risks.

Non-native species that travel with other species via various means, like pests on fruit.

Plant nurseries can unintentionally introduce non-native plants and pests, like whiteflies.

Evaluated by the number of species transported and their impact on ecosystems.
