A Preliminary Study on the Mechanisms of Growth and Physiological Changes in Response to Different Temperatures in Neopyropia yezoensis (Rhodophyta)

The results suggest that downregulation of Cyclin B and inactivation of ERK might be involved in negatively regulating the survival and division of protoplasts and the growth of gametophyte blades of N. yezoensis at high temperatures.

Indoor culture scaling of Gracilaria chilensis (Florideophyceae, Rhodophyta): The effects of nutrients by means of different culture media

In this study, the biomass, growth rate, and productivity of indoor cultures of G. chilensis were evaluated using various culture media and the positive results using the VS/BF-A medium could be attributed to the fact that BF provides different elements that are crucial, since they are involved in numerous physiological functions in the algae, and to the N:P ratio utilized, which positively affects growth and productivity.



Ocean acidification alleviates low-temperature effects on growth and photosynthesis of the red alga Neosiphonia harveyi (Rhodophyta).

Interactions between ocean acidification and temperature on the performance of a non-calcifying macroalga are demonstrated for the first time and the effects of low temperature on photosynthesis can be alleviated by increasing pCO2.

Effects of ocean acidification on growth and physiology of Ulva lactuca (Chlorophyta) in a rockpool‐scenario

The results indicated a slight enhancement of photosynthetic performance and significantly elevated growth of U. lactuca at future CO2‐concentrations and under conditions of limited water exchange when living in rockpools.

An Ocean Acidification Acclimatised Green Tide Alga Is Robust to Changes of Seawater Carbon Chemistry but Vulnerable to Light Stress

Future ocean acidification might impose depressing effects on green tide events when combined with increased light exposure, according to Ulva linza.

Responses of elevated CO2 on photosynthesis and nitrogen metabolism in Ulva lactuca (Chlorophyta) at different temperature levels

The results suggest that the responses to elevated CO2 in U. lactuca were temperature-dependent, and elevatedCO2 alone was less effective than temperature levels.

Zinc toxicity alters the photosynthetic response of red alga Pyropia yezoensis to ocean acidification

It is suggested that ocean acidification could alleviate the damage caused by Zn exposure, thus providing a theoretical basis for a better prediction of the impact of global climate change and heavy metal contamination on marine primary productivity in the form of seaweeds.

Effects of elevated CO2 on the photosynthesis and nitrate reductase activity of Pyropia haitanensis (Bangiales, Rhodophyta) grown at different nutrient levels

Results show that in CO2-enriched thalli, relative growth rate (RGR) was enhanced under nutrient enrichment, and it is proposed that accelerated photosynthesis could result in growth increment.

Photosynthetic activity and proteomic analysis highlights the utilization of atmospheric CO2 by Ulva prolifera (Chlorophyta) for rapid growth

Stress‐tolerance proteins appeared to have an important role in the response to salinity stress, whereas the abundance of proteins related to metabolism showed no significant change under low salinity treatments, which may be one of the main reasons for the extremely high growth rate of free‐floating U. prolifera when green tides occur.

Saturating light and not increased carbon dioxide under ocean acidification drives photosynthesis and growth in Ulva rigida (Chlorophyta)

Increased levels of CO2(aq) predicted for the future will not, in isolation, stimulate Ulva blooms and the shift in δ13C signatures from –22‰ toward –10‰ under saturating light but not under elevated CO2 (aq) suggest preference and substantial use to support photosynthesis and growth.

Impacts of increased atmospheric CO2 concentration on photosynthesis and growth of micro- and macro-algae

Altered physiological performances under high-CO2 conditions may cause genetic alteration in view of adaptation over long time scale, and marine algae may adapt to a high CO2 oceanic environment so that the evolved communities in future are likely to be genetically different from the contemporary communities.
