Biogeochemical fluxes through microzooplankton

Global Biogeochemical Cycles, 2010
Microzooplankton ingest a significant fraction of primary production in the ocean and thus remineralize nutrients and stimulate regenerated primary production. We synthesized observations on microzooplankton carbon‐specific grazing rate, partitioning of grazed material, respiration rate, microzooplankton biomass, microzooplankton‐mediated phytoplankton

Microzooplankton herbivory in the Ross Sea, Antarctica

Deep Sea Research Part II: Topical Studies in Oceanography, 2000
Abstract Microplankton abundances and phytoplankton mortality rates were determined at six stations during four cruises spanning three seasons in the Ross Sea polynya, Antarctica (early spring, Oct.–Nov. 1996; mid-late summer, Jan.–Feb. 1997; fall, Apr. 1997; mid-late spring, Nov.–Dec. 1997).

Winter distribution of microzooplankton in the Nordic Seas

2002
No abstracts are to be cited without prior reference to the author.Winter investigations of both phytoplankton and microzooplankton in open oceans are few, hence we know very little about the processes taking place outside the traditional growth seasons.

Guilds of ciliate microzooplankton in the Chesapeake Bay

Estuarine, Coastal and Shelf Science, 1991
Abstract The composition and abundance of three major guilds, or different trophic groups, of ciliates are reported for the Chesapeake Bay. Ciliates were classified either (a) macrophagous (consumers of nanoplankton-size or larger prey), (b) microphagous (consumers of picoplankton-size prey), or (c) predatory (consumers of other ciliates).

Microzooplankton Feeding Behavior and the Levy Walk

1990
We propose a Levy random walk model for the grazing behavior of swimming microzooplankton. In this model the path of the organism consists of straight line segments which are traversed at constant speed. The segments are at random angles, which correspond to sudden changes in direction, and the lengths of the line segments are random, with probability ...

Microzooplankton and seston in Akkeshi Bay, Japan

Hydrobiologia, 1976
Microzooplankton populations and other seston components in the water column were sampled from a central station in Akkeshi Bay, Japan for a year. The measurements reported in the present study constitute the first work on seasonal variation of microzooplankton and other seston components in Akkeshi Bay.

Microzooplankton and their herbivorous activity in the northeastern Atlantic Ocean

Deep Sea Research Part II: Topical Studies in Oceanography, 1993
Microzooplankton and their herbivorous activity were studied at four stations between 60 and 47°N along the 20°W meridian in mid-summer, as part of the 1989 U.K. Biogeochemical Ocean Flux Study. Microzooplankton were abundant in the surface mixed layer at all stations, with concentrations ranging between 2000 and 14,000 organisms l−1. The community was

Microzooplankton bacterivory and herbivory in the NE subarctic Pacific

Deep Sea Research Part II: Topical Studies in Oceanography, 1999
Abstract Despite a multi-decade time series of observations in the high nutrient, low chlorophyll regions of the NE subarctic Pacific, remarkably little is known about heterotrophic microbial processes, especially the role of microbes in the cycling of heterotrophic carbon through the lower food web. In this study, we quantified the seasonal patterns

Trophic interactions between nano- and microzooplankton and the “brown tide”

1989
The topic of nuisance algal blooms such as the brown tide’ has become a focus of attention in recent years for both the general public and the scientific community (Nuzzi, 1986; Olsen, 1986; Smayda, 1986, 1988; Okaichi et al., 1988; Wise, 1988). Attention has been drawn to the possibility of a correlation between man’s activities in the coastal zone ...
