Explore the 5 main types of algae: Brown, Green, Red, Diatoms, Dinoflagellates. Algae, often overlooked and underestimated, are foundational organisms in marine ecosystems. With somewhere between 30,000 to more than 1 million types of algae in the world, it is a surprise how these tiny photosynthesising, plant-like organisms get overlooked.
Jul 30, 2011 · Macroalgae on the other hand, derive all their nutrients directly from the surrounding water through their tissue, a bit like a sponge soaks up moisture, and their holdfasts are purely for physically anchoring the thallus to the seabed While seaweeds do reproduce sexually, their reproductive structures are mostly microscopic and require fine ...
Aug 1, 2018 · Marine macroalgae are mostly benthic organisms that are divided into three major groups according to their photosynthetic pigments. The distribution of seaweeds depends on various environmental factors and most importantly the quality and quantity of sunlight. Several species of seaweed reproduced asexually by means of vegetative growth.

Jan 1, 2010 · Abstract. Porphyra is a marine red macroalga represented by more than 130 species distributed worldwide. Most species are regarded as “winter seaweeds,” thus requiring low temperatures and low irradiances for optimal growth. Paradoxically, these seaweeds may stand harsh conditions in their natural environments, including extreme ...

Nov 10, 2023 · In marine macroalgae, asexual recycling often leads to the loss of gametophytes either along environmental gradients (e.g., Gabrielson et al., 2002) or as a consequence of anthropogenic introductions (e.g., Krueger-Hadfield et al., 2016). As meiosis occurs on sporophytic thalli, it is possible to recover sexual cycling and complete the life ...

Aug 6, 2023 · Particular microhabitats such as crevices and the territories of damselfishes play important roles in locally increasing the diversity of fleshy and turf algae. Inter-reef areas and Halimeda beds. Macroalgae associated with seagrass beds, particularly in deep, soft-bottom areas of the northern GBR are quite abundant.
May 13, 2020 · In macroalgae, it is well-established that dissolved inorganic carbon (DIC) acts as the trigger for signaling low water motion. Hence, evolutionarily developed signals of low water motion, suited for gamete-release, may be misleading in the future, potentially favoring opportunistic species in a broad range of marine organisms.
