Congrats to Sam Peña, Matassa Lab REU student, for receiving an undergraduate travel award to present her salt marsh research at ASLO Aquatic Sciences 2019! Sam did a fantastic job during her REU and presenting her research poster. Nice work, Sam!
I have the best field crew. This team persevered through some unexpected circumstances to crush 12 field sites in 5 days and many, many miles. Thanks for your hard work! -Catherine
Check out our new paper in Functional Ecology: 'Cascading effects of a top predator on intraspecific competition at intermediate and basal trophic levels'
On rocky shores, crowded, fast-growing barnacles (Semibalanus balanoides) compete for space and form clusters of elongated individuals called "hummocks." By consuming barnacles, carnivorous snails (Nucella lapillus) limit competition hummock development. However, by consuming snails or causing them to change their feeding behavior, predatory green crabs (Carcinus maenas) enhance barnacle competition and hummock development. Interestingly, crabs cause more hummocking even when they heave little or no indirect effects on barnacle density.
The pilot stand is built, and the tank fits!
Step 2: pilot plumbing. Then we replicate, replicate, replicate!
Research technician Emily L. and the "barnacle crusher" set up an experimental plot at the southern edge of Great Wass Island.
Sarah Donelan successfully defended her dissertation research investigating transgenerational effects of predation risk. Check out the first chapter from Sarah's dissertation in Ecology.
We have a new paper out this week in Proceedings of the Royal Society-B looking at food web complexity and predation risk. Check it out here!
