Feeling the pulse of Mumford Cove

Posted on by

23 March 2023. For almost 8 years now, the Evolutionary Fish Ecology Lab has conducted research in nearby Mumford Cove, a small, eelgrass covered embayment on eastern Long Island Sound. Using a set of battery-powered probes we have continuously measured temperature, pH, oxygen, salinity, and depth in 30 min intervals in the Cove - almost 120,000 times. This ongoing effort is not funded by any grant or institution; instead, it has been sustained over all these years by the firm belief in the prescient, if undervalued societal service of monitoring, an activity without short-term reward but important long-term benefits in understanding how ecosystems change on short and long time-scales. To commemorate the effort, we simply thought that it is time to show you some data, some pictures, and draw some early, cautious conclusions about the very interesting case of Mumford Cove. Have a look!

Fig.1: Schematic section of the upper part of Mumford Cove, showing the deployed probe (blue) between the bottom anchor (grey) and a subsurface float (orange), marked by a surface float (white). The probe sits in the deepest part of the Cove (Channel), at constant 50 cm distance to the bottom, but variable water level above (red histogram).

"Future generations will certainly have better theories, tools, models, and computers, but they will still depend on the data and measurements taken here and now."

[New publication] Complex CO2 x temperature effects in Menidia offspring

20 July 2018. We are happy to announce that Diversity just published Chris Murray’s paper on complex CO2 x temperature effects in Atlantic silverside offspring. The paper synthesizes 5 large multistressor experiments conducted since 2014, finding evidence for the large CO2 tolerance in this species across a large temperature range.

Congrats, Chris, to the second chapter published!

    M. menidia. Offspring responses to control (blue), high (red), and extreme (green) CO2 conditions at four temperatures across five CO2 × temperature factorial experiments. Traits include embryo survival (A–E), hatch length (F–I), larval survival (J–N) and larval growth rate (O–R). Individual replicates are represented by small faded circles. Treatment means (±SD) are depicted by large, bold circles and connected by dotted lines. Note: different scales used for hatch length measurements due to differences in sample timing; panels F and G use 1dph length Y axis (left) while panels H and I use hatch length Y axis (right).
