This process will hopefully encourage tourists to get more involved in national parks, start a conversation around invasive species, minimize the spread, and hopefully decrease the amount of money needed to remove the invasive species, since tourists will be working together to discourage the spread.

Both climate change and invasive species pose extraordinary ecological challenges to the world today.

Climate change is altering vital aspects of the environment like temperature and precipitation, the frequency of extreme weather events, as well as atmospheric composition and land cover. The temperature, atmospheric concentration of carbon dioxide CO2 and available nutrients are the key factors that will drive species survival; changes in these factors will most likely stress the ecosystems and the chances of invasions [ 3 , 4 ]. The process of establishment of species has received wide research attention. Many scientists agree that climate change will alter destination habitat and increase vulnerability to invasion because of resource scarcity and increased competition among native fauna and flora.

It remains uncertain whether increasing concentrations of CO 2 in the atmosphere will generally favor non-native plant species over native plant species. Some research is suggesting that elevated CO 2 concentrations might hinder the pace of recovery of some native ecosystems after a major disturbance, like flood or fire. This could potentially lead to increased dominance of invaders in some regions [ 3 ]. Changes in the atmospheric composition could decrease the rate at which plants transpire and result in a higher availability of moisture in the soils underneath.

In that scenario, it could be expected that in ecosystems where growth is limited by water availability, species that could take advantage of extra water could become more abundant. Another effect of climate change could be increases in nitrogen deposition driven by fossil fuel combustion. In general, higher nitrogen concentrations favor fast-growing plant species. In some regions of the world, for instance in Europe, many plant ecosystems are adaptive and responsive to changes in nitrogen, and therefore changes in its concentration will not make them more vulnerable to invasions. However, in other regions including parts of North America , many of the most adaptive plant species are alien grasses that are likely to proliferate and hinder the survival of native species.

Thus, impacts of nitrogen deposition on invasions are likely to vary by region [ 3 ]. Finally, changes in precipitation and temperature will have the most profound impact on the geographic ranges of many species. Currently Florida and Hawaii are the two states most affected by invasive species, in part due to their mild climates. Changes in precipitation could cause water-loving or water-resistant species to outcompete one another [ 4 ]. Rising temperatures would allow the spread northward of some species currently restricted in their northern ranges due to, for example, the probability of an early freeze. Increasing temperatures can enhance winter survival of some invasive organisms that would not survive otherwise [ 3 ].

Shifting species habitats can also result from natural climate fluctuations and geographical species migration. One good example is in the Western United States where a warming climate will cause various species to migrate to higher elevations. Some native species that will not be able to migrate upward at the same pace can be lost as a result. Such stressed ecosystems may have more available resources that could facilitate the successful invasion of non-native plants [ 5 ]. Some studies have shown that a short-term increase in changing conditions may facilitate the long-term establishment of alien plant species.

Accelerating anthropogenic climate change might disadvantage species that cannot quickly extend their range and that have long generation times. Species that are able to shift ranges quickly might have an advantage. Species that are spread over a large latitudinal distance and thus tolerate a wide range of climates tend to be the most successful invaders [ 6 ]. When it comes to trade and the transmission of invasive organisms, changing climatic conditions influence three fundamental elements of invasion mechanism: the source location, the pathway and the destination. There are a few possible scenarios of the climate change impact on pathways and destinations.

From one point of view, it can become a limiting factor. Overpopulation, and consequently water shortages, can disrupt the fragile balance of food supplies. In that sense, climate change can have a negative impact on the pathways and decrease the risk of the interception of invasive species in different countries. From another perspective, extreme events are likely to result in an increasing volume of migrating climate refugees.

Displaced people are likely to bring goods, food and livestock that can be contaminated with larvae or an organism that may invade the new habitat where they relocate [ 2 ]. Climate change and melting ice in the Arctic can also facilitate the process of opening new trade routes to ship goods and consequently invasive pests hitchhiking with transported commodities. Historically, botanical and ornamental gardens have also been the sources for many plant invasions worldwide, once preadapted species escaped. Those plants that can survive only due to intentional cultivation might be able to disperse if the climate shifts in their favor. Some species can also disperse in areas that receive artificial treatment such as artificial irrigation. Many invasive organisms have an adverse impact on human health.

Nonnative species can cause a disease and they can also vector a disease, which itself can be either native or non-indigenous. Modern trade and movement of commodities are greatly facilitating the dispersal of disease vectors. One recent case is the Asian tiger mosquito Aedes albopictus whose larvae were imported to the US on container ships carrying used car and truck tires Picture2. This mosquito is an efficient vector for many viruses including dengue, yellow and West Nile viruses and therefore its dispersal raised big public health concerns at various global destinations where it was introduced and was able to become established [ 7 ].

It is important to remember that today it would most likely be impossible to feed the population of the United States with only native plants. However, some dangerous invasive organisms can be accidentally introduced with crop seeds, soil or with various imported plant materials. Many of them, mostly weeds and plant pathogens, are causing several billions of dollars annually in losses to the US economy from crops, pastures and forests. Finally, invasions alter a wide range of ecosystem functions including productivity, hydrology and nutrient cycling. Invaders change the rules of survival for all species in a given ecosystem and tremendously affect their function.

The most irreversible impacts are genetic extinctions. Other possible effects include reduction in biodiversity, major genetic changes and production of an entirely new, highly invasive species [ 9 ]. Invasive plant species can be both the result of global changes and the drivers of change.
