Fossil Chironomidae assemblages (with a few Chaoboridae and Ceratopogonidae) from Zagoskin and Burial Lakes in western Alaska provide quantitative reconstructions of mean July air temperatures for periods of the late-middle Wisconsin (w39,000–34,000 cal yr B.P.) to the present. Inferred temperatures are compared with previously analyzed pollen data from each site summarized here by indirect ord...
Large populations of non-biting midges (Chironomidae) that emerged from waste water stabilization ponds in central Israel created severe nuisance to nearby residents in 1998. A study was begun in summer 1998 to examine the dynamics and phenology of the population as a basis for a successful control strategy. The extensive waste pond area required the development of efficient, reliable and compe...
The purpose of this study was to document existing benthic organisms of the lower West River in New Haven and West Haven, Connecticut, in order to enable monitoring of salt marsh restoration. Seventeen sites were sampled between the Chapel Street Bridge and the mouth of the West River during the month of July 1995. All sites contained polychaete worms and other organisms typical of estuarine sy...
