Dynamic measurements of black oystercatcher (Haematopus bachmani) predation on mussels (Mytilus californianus)

A black oystercatcher foraging in central California

Myself and co-author Wes Dowd have a new paper out in the journal Invertebrate Biology detailing a set of observations we made of black oystercatchers attacking a set of mussels that were part of an experiment we were running. The mussels in our experiment were wearing a set of sensors, including an internal temperature sensor, a valve gape sensor (aka a ‘valvometer’), and a 3-axis accelerometer and magnetometer sensor. These mussels were part of a bed of live mussels (image below) … Continue Reading

Waterproofing sensors for mussel monitoring

We have recently published two new papers in the Journal of Experimental Biology detailing the results of field experiments we carried out. Our goal was to monitor the behavior and internal temperatures of sea mussels (Mytilus californianus) on the shoreline, and link their recent experiences to their physiological status. There can be substantial variation in the environmental experience of mussels sitting only a few centimeters away from each other, and this project was an attempt to catalog that variation for the first time in a wave-swept rocky intertidal environment. This project involved the development of a new datalogger system (MusselTracker) … Continue Reading
