Translocation of 14 C in Macrocystis pyrifera ( Giant Kelp ) 1
The pattern of import and export of IC-labeled assinuates in Macrocystis pyrifers (L) C. A. Agardh in southern California was studied by labeling single blades on frods, in situ, with I'4CINaHCO3 for 24 bours. The pattem was found to be similar to that known in dicotyedons: actively growing tissue imported and did not export. As a blade reached maturity it began to export, at first only acropet...
متن کاملTranscriptomic analysis of metabolic function in the giant kelp, Macrocystis pyrifera, across depth and season
To increase knowledge of transcript diversity for the giant kelp, Macrocystis pyrifera, and assess gene expression across naturally occurring depth gradients in light, temperature and nutrients, we sequenced four cDNA libraries created from blades collected at the sea surface and at 18 m depth during the winter and summer. Comparative genomics cluster analyses revealed novel gene families (clus...
متن کاملCopper tolerance and distribution of epibiotic bacteria associated with giant kelp Macrocystis pyrifera in southern California
Kelp forests in southern California are important ecosystems that provide habitat and nutrition to a multitude of species. Macrocystis pyrifera and other brown algae that dominate kelp forests, produce negatively charged polysaccharides on the cell surface, which have the ability to accumulate transition metals such as copper. Kelp forests near areas with high levels of boating and other indust...
متن کاملDensity derived estimates of standing crop and net primary production in the giant kelp Macrocystis pyrifera
Assemblages of macroalgae are believe to be among the most productive ecosystems in the world, yet difficulties in obtaining direct estimates of biomass and primary production have led to few macroalgal data sets from which the consequences of long-term change can be assessed. We evaluated the validity of using two easily measured population variables (frond density and plant density) to estima...
متن کاملBioaccumulation of copper and zinc by the giant kelp Macrocystis pyrifera
This study examined the bioaccumulation of the heavy metals copper (Cu) and zinc (Zn) by the giant kelp, Macrocystis pyrifera, by exposing meristematic kelp tissue to elevated metal concentrations in seawater within laboratory aquaria. Specifically, we carried out two different experiments. The first examined metal uptake under a single, ecologically-relevant elevation of each metal (30 ppb Cu ...
