This is a story of success and failure. It is a story where a good thing becomes and bad thing and back again, maybe. This is the story of the tamarisk bush and it's spread through the American southwest.Read More
Imagine you’re walking along the banks of a river in Maine, listening to the twittering of birds and marveling at the beautiful view across the meadows of marsh grass to the sparkling water. Something catches your eye. It’s bright! As you walk closer to investigate, it starts to take on a familiar shape, but… it can’t be…Read More
Not all non-native species become invasive. Most do not. Many, many plants have been introduced to new areas for agriculture, horticulture, ornamentals, etc., without a problem. So what makes some plants invade, while others never do?Read More
The history of the rocky intertidal of the northeastern coast of North America is a history of alien invasion. A stroll, or more realistically scramble, along the coast today reveals a community that is dramatically different than that observed by the early European colonists in New England.Read More
This is an update to my previous post: On the look for invasive species.
Have you ever wondered what was growing under the docks up and down our coast?
Well 25 scientists set out to answer just that. Scientists (including Sara, Seth, and myself), in a six-day sweep, scoured the docks from Maine to Rhode Island looking for and identifying introduced species.Read More
Scientists, people with yards, and nature lovers generally all agree that invasive plants are the worst. Mention buckthorn or multiflora rose at a party and I bet you won’t hear anyone say how much they like them. Before we go on, check out Christopher Wells’ post, Why Study Invasive Species?
So, does anyone have a reason to like invasive plants? I’m looking for a silver lining, to help me sleep at night. I have nightmares of Japanese knotweed gradually covering the New England area, such that wildflowers and trees are merely a memory.Read More
I’ve always been interested in community ecology: the study of the organization
and interactions within a group of organisms (predation, herbivory, symbiosis). Interactions within a biological community
fluctuate around equilibrium until they are disturbed...
On a survey looking for introduced (non-native) species carried out in 2000 they found this beautiful sea anemone (Sagartia elegans).
It was only found in one marina: Hawthorne Cove Marina in Salem Harbor,
MA (along with quite a few other neat introduced animals and plants).
