The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013).

The southern California populations had substantial resprouting with some seedling recruitment. The Monterey populations had no resprouting ability and recovery was entirely by seedlings. However, there is an age effect in that when young these northern California populations fail to recruit seedlings due to lack of a seed bank buildup in the short interval since the last fire. These populations likely will be extirpated. I hypothesize that this obligate seeding mode has been selected for because seed reproduction is more...

It is the longest known continuous trawl survey in Lake Erie. In addition to spanning over 50 years, the data series is unique for three prominent design elements: 1) sampling was conducted at three depth strata; 2) replicate trawl samples were collected at each depth stratum; and 3) sampling was conducted during both day and night. Unlike other trawl series collected in Lake Erie, and throughout the Great Lakes, the East Harbor program is the only one to combine these sampling practices in a single survey.
