Feb. 26—COLLEGE STATION — Invasive species cause many negative impacts to the Texas landscape, from the displacement of native trees to potentially wiping out entire species. Because of their ...
The Lone Star State is home to over 200 ant species, but the one that truly packs a punch is the red imported fire ant, according to Texas Parks and Wildlife Department. These ants produce a ...
The invasive beetle that kills ash trees has traveled to new areas in Texas. Texas A&M Forest Service confirmed last week that the emerald ash borer is now in five counties in North and Central Texas.
In the 1930s, colonies were accidentally introduced into the United States through the seaport of Mobile, Alabama.Despite earlier views that cargo ships from Brazil docking at Mobile unloaded goods infested with the ants, [1] recent DNA research confirmed that the likely source population for all invasive S. invicta in the United States occurred at or near Formosa, Argentina, and virtually ...
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 ...
Non-native invasive species can disrupt ecosystems because they do not have natural predators, or other ecological checks-and-balances. Thus, with less competition from native species, non-native populations can explode. [9] Invasive insects and pathogens have eliminated entire tree species from forests of the United States in as little as decades.
For example, the damage caused by 79 invasive species between 1906 and 1991 in the United States has been estimated at US$120 billion. Similarly, in China, invasive species have been reported to reduce the country's gross domestic product (GDP) by 1.36% per year. [109] [114] The management of biological invasions can be costly.
