Phytoplankton control by grazing zooplankton: A study on the spring clear-water phase l
We tested the hypothesis that a clear-water period, regularly observed in many mesoand eutrophic lakes, is caused by grazing herbivorous zooplankton. Such a clear-water phase occurs during mid-May in the moderately eutrophic Schiihsee and involves a rapid increase in Secchi transparency, and a drop in chlorophyll and particulate organic carbon in size fractions ~35 Nm. Maxima of zooplankton bio...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
The Impact of Zooplankton Grazing on Phytoplankton Species Composition and Biomass in Lake Champlain (USA-Canada)
Rates of grazing on phytoplankton by macrozooplankton (cladocerans and copepods > 220 μm in length) and microzooplankton (animals < 220 μm, mostly rotifers and nauplii) were determined for Lake Champlain on three occasions using a modified version of the Lehman-Sandgren method. Gradients in grazer density were created in fertilized cubitainers incubated in situ, and clearance rates on specific ...
متن کاملModeling migratory grazing of zooplankton on toxic and non-toxic phytoplankton
Migratory grazing of zooplankton between non-toxic phytoplankton (NTP) and toxic phytoplankton (TPP) is a realistic phenomena unexplored so far. The present article is a first step in this direction. A mathematical model of NTP–TPPzooplankton with constant and variable zooplankton migration is proposed and analyzed. The asymptotic dynamics of the model system around the biologically feasible eq...
