Item The biology of the oyster community and its associated fauna in Delaware Bay(Newark, College of Marine Studies, University of Delaware., 1973) Maurer, Don; Watling, LesThe purpose of this account is to describe the composition of the associated invertebrate fauna of Delaware Bay oyster beds, and to determine the effect of salinity, substrate, and season on this fauna. The dependence of the number of species in a bed community on maximum salinity is discussed, together with its temporal variability. The associated oyster fauna of Delaware Bay is very similar to estuaries throughout the world and thus this report may have more than local interest.Item Ecological studies on benthic and planktonic assemblages in lower Delaware Bay(College of Marine Studies University of Delaware, Lewes, Delaware, 1976) Watling, Les; Maurer, DonThis study was undertaken to obtain baseline ecological data in Delaware Bay. During the summers of 1972 and 1973 the first bay-wide quantitative survey of benthic organisms was conducted. The survey consisted of 207 samples distributed over 26 transects from the bay mouth to Woodland Beach, Delaware. Based on the results of the bay-wide survey reported herein, it was decided to conduct an intensive study in the oil lightering area in lower Delaware Bay (1974-1975). The intensive study included quantitative monthly investigations of phytoplankton and zooplankton together with quarterly investigations of the benthos. Two 12hour plankton studies were also conducted. In addition to the quantitative benthic studies, there were extensive samples with dredge hauls. Data from dredge hauls and grabs were compared to determine whether a useful method of community analysis could be developed based on dredge data alone. It was concluded, that such a method was feasible but that it required additional refinement. Some of the survey data were never reported for Delaware Bay prior to this study.Item Guide to the macroscopic estuarine and marine invertebrates of the Delaware Bay region(Newark, College of Marine Studies, University of Delaware., 1973) Watling, Les; Maurer, DonThis volume represents the first major compilation of invertebrate species for the Delaware Bay region. Included in the volume are: a key to the major kinds of invertebrates in this region; taxonomic listings of over 300 species collected by the authors or referred to in other published papers; keys to these species; lists of species which, because of their known geographic distribution, may be expected to occur in this region; and a comprehensive bibliography of papers dealing with the species listed.
