Chlorophyll Turnover in Skeletonema costatum, a Marine Plankton Diatom [PDF]

open access: yesPlant Physiology, 1979
[(3)H]- and delta-[(14)C]Aminolevulinic acids were incorporated into the chlorophylls of Skeletonema costatum, a marine plankton diatom. In the stationary phase of growth, the tetrapyrrole-based pigments reached steady-state labeling after 10 hours. Under conditions of exponential cell division and chlorophyll accumulation, (3)H was rapidly lost from ...

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-

Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed biodiversity monitoring across taxa from bacteria to mammals, yet sample collection remains a major bottleneck. Passive sampling via adsorption and entrapment has emerged as a promising alternative to overcome the limitations of conventional active filtration.
