TIPPC Declares Position on H.B. 338
The Texas Invasive Plant and Pest Council is in opposition to Texas H.B. 338. H.B.338 represents a great step backwards in Texas’s long and ongoing battle to prevent and limit the introduction and spread of noxious and invasive species. The language of H.B. 338 undermines the validity of concerns about invasives expressed by other government agencies, universities, and organizations; diminishes the intellectual value of research and publications on invasive species; is ambiguous on the definition of “invasive species”; and would place an undue financial burden on organizations wishing to inform the public about noxious and invasive species. TIPPC encourages you to act quickly and contact your legislators and express your opinion on H.B. 338. - For More Information

Invasive Spotlight: Island Applesnail
(Pomacea insularum)
Native to South America and introduced through the dumping of aquariums into freshwater ecosystems, the island Applesnail (Pomacea insularum) has historically been confused with the channeled Applesnail. The shell of the island applesnail varies from 1.5 - 2.3 inches wide and 1.75 - 3 inches high (about the size of a baseball or human fist). Patterning on the shell varies, but is usually banded brown, yellow-tan, or even blackish. Body color of applesnails vary from yellow to brownish black, with or without dark spiral bands. Their presence is often first noted by observation of their bright pink egg masses.
Negative ecological effects of this herbivorous snail include impacts on wetlands and wetland restoration, competition with native snails, and the introduction of exotic parasites. Serious economic loss from damage to rice crops has been documented in Asia, and, in Texas, rice farmers experience increased maintenance costs for levees in fields with large populations of applesnails due to the constant burrowing by snails.

Citizen Science Success
In 2007, astronomer Chris Lintott and his colleagues were drowning in data, 1 million images of galaxies to characterize and only one graduate student to do it. So Lintott and his collaborators set up a Web site in hopes of attracting some volunteers. Hoping for a few thousand helpers, the site Galaxy Zoo "went viral," and the current count is 375,000 people working from the comfort of their own homes. More than 20 astronomical papers have come out of the project, including the discovery of two astronomical phenomena. Now Lintott's team has expanded its citizen-science efforts to other projects, including studies of the moon and an analysis of old ship logs for climate data. - Learn More
