An invasive species is an introduced species that harms its new environment. [2] Invasive species adversely affect habitats and bioregions , causing ecological, environmental, and/or economic damage.
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 ...
This explains why areas in the United States such as Hawaii, Florida, and California are infested with invasive species. [3] These invasions are one of the biggest and most consistent threats to biodiversity across the globe. Antarctica is the only natural reserve on Earth that is without invasive species, due to its environmental factors. [2]
For example, a study conducted in the Mojave Desert of California by Smith et al. in 2006, found that invasive grass species increase in areas with higher concentrations of carbon dioxide (CO 2), especially in arid conditions which make up 20% of Earth’s terrestrial surface area. [3]
However, some plants grow a little too well. “Invasive plants spread aggressively and cause environmental changes, such as the elimination of native plant populations,” says Justine Kandra ...
Here, a gardening expert outlines common invasive plants, what an invasive plant is, how to get rid of them, and the threats they pose to U.S. agriculture.
Climate change is likely to favour some invasive species and harm others, [3] but few authors have identified specific consequences of climate change for invasive species. [4] As early as 1993, a climate/invasive species interaction was speculated for the alien tree species Maesopsis eminii that spread in the East Usambara mountain forests ...
Specifically, biological pollution is the introduction of non-indigenous and invasive species, [1] otherwise known as Invasive Alien Species (IAS). When the biological pollution is introduced to an aquatic environment, it contributes to water pollution. Biopollution may cause adverse effects at several levels of biological organization:
