Many Antarctic macroalgae synchronize their reproductive processes to cope with the seasonal variations in daylengths. In algae exhibiting a heteromorphic life-history, the development of small gametophytes and large sporophytes is seasonally determined and involves different physiological adaptations.

This strategy ensures the completion of the life-cycle under seasonally changing light conditions. Low light requirements for growing and photosynthesizing are developed to cope with Antarctic seasonality and constitute adaptations to expand depth zonation of macroalgae.

The paper summarises the present knowledge of seaweeds from both polar regions with regard to the following topics: the history of seaweed research in polar regions; the environment of seaweeds in polar waters; biodiversity, biogeographical relationships and vertical distribution of Arctic and Antarctic seaweeds; life histories and physiological thallus Cited by: from book Life in Extreme Environments (pp) Life strategy, ecophysiology and ecology of seaweeds in polar waters Article January with Reads.
At lower latitudes, e.g. close to the northern limit of the Antarctic region, in the South Shetland Islands, daylength varies between 5 h in winter and 20 h in summer (Wiencke a). This extreme light regime has strong implications for primary productivity in general and for the seasonal development of seaweeds.

In addition to their extreme ecological importance they are also of high economic relevance. Complementing available textbooks with its more research-oriented approach, this volume contains 22 3/5(1). Seaweeds (macroalgae) represent the most striking living components in the Antarctic’s near-shore ecosystems, especially across the West Antarctic Peninsula and adjacent islands.
Due to their abundance, their central roles as primary producers and foundation organisms, and as sources of diverse metabolically active products, seaweed. Macroalgae samples.
Samples of macroalgae C. jacquinotii, I. cordata, H. grandifolius, and P. endiviifolia were collected during the expeditions integrating the Brazilian Antarctic Program, between January and Februaryin Admiralty Bay, at different sites on King George Island, Antarctica.

Before this, the life history of Antarctic seaweeds was mostly unknown and eco-physiological data fragmentary.

Part II covers seaweed ecophysiology, including the relationships of light, temperature, salinity, and .Light (PAR; photosynthetically active radiation) is generally considered the most important environmental variable for Antarctic macroalgae, particularly since inorganic nutrient levels are rarely, if ever, growth limiting and annual temperature variations are small [7,26].
