Compensation due to density-dependent mechanisms is essential for the maintenance of an exploited fish stock. Understanding compensation is important for understanding population regulation and responses to added mortality. We examined possible densi

Three decades of discussion and study have not resolved the apparent discrepancy between N-limitation of primary production and the ability of marine ecosystems to fix N. We use a simple model as a heuristic tool to examine controls on nutrient cycli

In Westernport and Port Phillip Bays, Victoria, Australia, copepods previously identified as Acartia clausi Giesbrecht or Acartia tranteri Bradford form polymodal length-frequency distributions at some times of the year. The three size morphs of Acar

Infection of copepods by parasitic dinoflagellates has been known for many years, but the ecological consequences of this parasitism have been largely neglected. We estimated mortality rates in the copepodParacalanus indicus Wolfenden due to parasiti

Spatial patterns of abundance of the zooplankton of Tomales Bay, California, were studied over one year from August 1987 to September 1988. Samples were taken on six transects up the long axis of the bay, and the species composition and abundance of

Definitions and mathematical expressions currently used to calculate secondary production are based on the observation of development in cohorts. Most populations of marine zooplankton and many benthic populations do not meet the strict conditions ne

Egg production rate of the copepod Acrocalanus inermis was measured at 3 stations in south Kaneohe Bay, Hawaii in August 1977 and July–October 1979. The egg production rates were significantly variable spatially, but temporal variability over a tim

We measured the growth rate of Acartia tranteri and related variables in Westernport Bay, Australia, on 19 occasions in 1982-1984. Acartia tranteri is numerically dominant in the bay zooplankton, with a mean abundance of all life stages of 12,000 m-3
