Zooplankton distribution and dynamics in a temperate shallow estuary

Synchronous dynamics of zooplankton competitors prevail in temperate lake ecosystems.

Although competing species are expected to exhibit compensatory dynamics (negative temporal covariation), empirical work has demonstrated that competitive communities often exhibit synchronous dynamics (positive temporal covariation). This has led to the suggestion that environmental forcing dominates species dynamics; however, synchronous and compensatory dynamics may appear at different lengt...

Zooplankton sample variability in a tidal estuary :

A series of 347 vertical zooplankton hauls was made at a 175-h anchor station in the upper St. Lawrence estuary, Quebec, and current meter profiles were recorded. The 95% confidence interval of a single observation in most of the copepod time series was about 25400% of the mean. Temporal variability consisted for the most part of semidiurnal fluctuations superimposed on a long term trend. Other...

The distribution and speciation of dissolved trace metals in a shallow subterranean estuary

Sediment transport and dispersion in a cool-temperate estuary and embayment, Saco River estuary, Maine, USA

Article history: Received 11 June 2007 Received in revised form 12 February 2008 Accepted 20 February 2008 The Saco River flows through a rock bound, mid-latitude estuary recognized as the primary source of sand to the Saco Bay barrier beach system. To better constrain the conditions under which the Saco River contributes sand to Saco Bay, three moorings equipped with current meters and a CTD w...

Contaminants of emerging concern in a large temperate estuary.

This study was designed to assess the occurrence and concentrations of a broad range of contaminants of emerging concern (CECs) from three local estuaries within a large estuarine ecosystem. In addition to effluent from two wastewater treatment plants (WWTP), we sampled water and whole-body juvenile Chinook salmon (Oncorhynchus tshawytscha) and Pacific staghorn sculpin (Leptocottus armatus) in ...
