Welcome to Dalhousies Invasive Species Website. This site focuses on the spread of two recent invaders of Nova Scotias coastal waters: a seaweed - Codium fragile ssp. tomentosoides and a colonial invertebrate - Membranipora membranacea. Here you ll find information on what they are, where they are, how you can help monitor their spread, and lots more. This website was designed as part of my MSc thesis project which you can read more about here. Just click on the picture of your species of choice to find out more. And remember, if you have any information on either species you would like to share please feel free to contact me.
