the  12 Days of Christmas - Aquatic Invasive Species version


Revisiting Darwin
     
 
To many of us it seems like invasive species are a relatively new issue. However, even as he was developing his theory of evolution, Charles Darwin was thinking about the impacts of invasion. Darwin held that the ability of a species to become an effective invader would depend on how closely related the invader is to the native species present.

Known now as "Darwin's naturalisation conundrum", he thought that if the new species is closely related it would have a tough time establishing. On the other hand, species not closely related to those already in the habitat would establish more easily, and might become invasive.

New research now shows that the ability of a species to invade a new habitat is much more dependent upon the existing species relationships with each other. In brief, they found that in a system where there is strong existing competition between species an invader is less likely to thrive.  Read More

     We review news stories on a daily basis and post stories of interest on Facebook as we find them. However, we know that many of you are not using Facebook so here are the links we posted during October on our Facebook pages.

   Happy Holidays! I hop that you all enjoy a happy and healthy holiday season and wish you all the best in 2014. This issue of the Clean Angling News is our annual Holiday issue that combines November and December. We have found a lot of great links that are included. Be sure to check out the variety of stories we have featured in this issue.

   I want to take a minute to highlight one of the stories that really illustrates the many ways we spread invasives without ever thinking about it. In this case, the famous American singer, Katy Perry found that her latest album sent to Australia was considered to be a "Biohazard" and all copies were confiscated to prevent the introduction of exotic species. It turns out the albums came in a package designed to be planted. The packaging material was filled with embedded flower seeds designed to be planted to produce a flower garden. Unfortunately, no one ever considered the invasion risk until Australian authorities confiscated the entire shipment. Read More

   We get more questions about felt bans than anything else and word has reached us that South Dakota is implementing a ban in 2014. For those who are concerned, our Status of US Felt Restrictions page is where we track every felt ban or proposal that we know of. We update this page whenever we get new info (note that we have not included the South Dakota ban until we get more info).

   I hope you will get in touch with me if you have questions or invasive species stories to share.
