Interactive eVects of light and nutrients on phytoplankton stoichiometry
The stoichiometric composition of autotrophs can vary greatly in response to variation in light and nutrient availability, and can mediate ecological processes such as C sequestration, growth of herbivores, and nutrient cycling. We investigated light and nutrient eVects on phytoplankton stoichiometry, employing Wve experiments on intact phytoplankton assemblages from three lakes varying in prod...
متن کاملEffects of salinity, temperature, light intensity and light regimes on production, growth and reproductive parameters of Apocyclops dengizicus
The effects of salinity, temperature, and light conditions on production and development, longevity, survival and sex ratios of the cyclopoid copepod, A. dengizicus were determined. Seven different salinity levels (5, 10, 15, 20, 25, 30, 35 psu), four temperatures (20, 25, 30, 35 °C), three different light intensities (33.3, 85.3, 162.1 μmol photons/ m2/ s) and light regimes (24:0, 0:24, and 12...

متن کاملPhytoplankton communities and stoichiometry are interactively affected by light, nutrients, and fish
We examined the separate and interactive effects of light, nutrients, and zooplanktivorous fish on phytoplankton nutrient stoichiometry, taxonomic richness, community composition, and the associations among these variables. We manipulated light supply, nutrient supply, and zooplanktivorous fish (presence or absence), in a factorial design using mesocosms containing regional phytoplankton and zo...
متن کاملGrowth rates of phytoplankton under fluctuating light
1. The effect of light fluctuations on the growth rates of four species of freshwater phytoplankton was investigated. Experimental light regimes included constant irradiance and fluctuations of a step function form, with equal proportion of high (maximum of 240 mmol photons m s) and low light (minimum of 5 mmol photons m s) (or dark) in a period. Fluctuations of 1, 8 and 24-h periods were impos...
