A provincial aquatic invasive species survey conducted by DFO in October has confirmed that Violet Tunicate is present in Belleoram, Fortune Bay, Newfoundland, Canada. The tunicate was detected on boat hulls, wharf pilings and rocks in Belleoram. Full Article

Ailanthus Research: Please Send Seeds

Hello all. My name is Emmi Felker-Quinn, and I am a graduate student at the University of Tennessee. I am starting a research project on the invasive plant tree-of-heaven (Ailanthus altissima). I am interested in looking at how traits related to invasability vary inpopulations across the United States. To that end, I am interested in collecting seeds from tree-of-heaven from different locations. However, as a first-year graduate student my opportunities for travel are fairly limited, so I am asking for help from people interested in invasive plants. If you have tree-of-heaven growing near you and can easily collect seeds and mail them to me, I would greatly appreciate your help. More Information
