Effect of Salinity Differences on Phytoplankton Density (Skeletonema costatum)

open access: yesEdunity Kajian Ilmu Sosial dan Pendidikan, 2023
This study aims to determine the effect of differences in salinity on the density of phytoplankton (Skeletonema costatum). The method in this study used a completely randomized design with 4 treatments and 3 replications. The parameters tested included the density rate of Skeletonema costatum. Data analysis uses One Way Anova to see the significance of

Inhibitory effect of Salicornia europaea on the marine alga Skeletonema costatum [PDF]

open access: yesScience China Life Sciences, 2012
Exploiting the negative biochemical interference between plants and algal species has been suggested as a method to control harmful algal blooms. In this work, we investigated the inhibitory effect of the salt marsh halophyte Salicornia europaea against the marine alga Skeletonema costatum. S. europaea suppressed the growth of S. costatum in a nutrient-

Flexible C : N ratio enhances metabolism of large phytoplankton when resource supply is intermittent [PDF]

open access: yes, 2014
. Phytoplankton cell size influences particle sinking rate, food web interactions and biogeographical distributions. We present a model in which the uptake, storage and assimilation of nitrogen and carbon are explicitly resolved in different-sized ...
