To understand the effects of variable water masses in northeastern East China Sea (Korea South Sea), planktonic copepods were seasonally sampled. Out a total 106 copepod species, 85 oceanic warm-water and number species varied summer, autumn, spring, winter. The study area was divided into two or three regions according to degree influence masses. Canthocalanus pauper, Clausocalanus furcatus, O...

Zooplankton play a pivotal role in connecting primary producers and high trophic levels, changes their temporal spatial distribution may affect the entire marine ecosystem. The seasonal taxonomic composition patterns of mesozooplankton Bohai Bay were investigated relation to number water parameters. is eutrophic semi-enclosed bay with dynamic physico-chemical conditions influenced by terrestria...

This paper presents information from different sampling surveys carried out along the Santa Catarina coast in order to outline the biogeographical characteristics of the zooplankton in this region and identify species or groups of species with potential use as bioindicators. Based on a checklist of species of the zooplankton community in the state, it was observed that, in the warmer months of ...

Zooplankton has a non-random distribution in the pelagic community and exhibits various levels of patchiness (HAURY et al., 1978). Recently, particular attention has been focused on investigating the small-scale vertical and horizontal distribution of zooplankton assemblages which are important for monitoring marine processes and disturbances to marine ecosystems (PAFFENAn investigation into th...

The estuarine planktonic copepods have a wide geographical distribution and commendable tolerance to various kinds of contaminants. The primary aim of the present study was to contrast the impacts of model POPs (TBBPA and HBCD) on three common estuarine planktonic copepods (Oithona similis, Acartia pacifica and Pseudodiaptomus inopinus) and establish a protocol for the assessment of acute toxic...

Understanding the impact of climate change on zooplankton populations is of major importance, as they represent the basis for higher trophic levels in the marine food web. In this study we analyze the 36-year copepod abundance time series in the Gulf of Trieste, northern Adriatic, to investigate its interannual variability, with particular attention to species trends and phenology. Following th...

Copepods swim either continuously by vibrating their feeding appendages or erratically by repeatedly beating their swimming legs, resulting in a series of small jumps. The two swimming modes generate different hydrodynamic disturbances and therefore expose the swimmers differently to rheotactic predators. We developed an impulsive stresslet model to quantify the jump-imposed flow disturbance. T...
