RED ALGAE · RHODOPHYTA Rhodophyta Are Cosmopolitan, Found from the Artic to the Tropics
RED ALGAE · RHODOPHYTA Rhodophyta are cosmopolitan, found from the artic to the tropics. Although they grow in both marine and fresh water, 98% of the 6,500 species of red algae are marine. Most of these species occur in the tropics and sub-tropics, though the greatest number of species is temperate. Along the California coast, the species of red algae far outnumber the species of green and brown algae. In temperate regions such as California, red algae are common in the intertidal zone. In the tropics, however, they are mostly subtidal, growing as epiphytes on seagrasses, within the crevices of rock and coral reefs, or occasionally on dead coral or sand. In some tropical waters, red algae can be found as deep as 200 meters. Because of their unique accessory pigments (phycobiliproteins), the red algae are able to harvest the blue light that reaches deeper waters. Red algae are important economically in many parts of the world. For example, in Japan, the cultivation of Pyropia is a multibillion-dollar industry, used for nori and other algal products. Rhodophyta also provide valuable “gums” or colloidal agents for industrial and food applications. Two extremely important phycocolloids are agar (and the derivative agarose) and carrageenan. The Rhodophyta are the only algae which have “pit plugs” between cells in multicellular thalli. Though their true function is debated, pit plugs are thought to provide stability to the thallus. Also, the red algae are unique in that they have no flagellated stages, which enhance reproduction in other algae. Instead, red algae has a complex life cycle, with three distinct stages. -
Red Algae (Bangia Atropurpurea) Ecological Risk Screening Summary
Red Algae (Bangia atropurpurea) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, February 2014 Revised, March 2016, September 2017, October 2017 Web Version, 6/25/2018 1 Native Range and Status in the United States Native Range From NOAA and USGS (2016): “Bangia atropurpurea has a widespread amphi-Atlantic range, which includes the Atlantic coast of North America […]” Status in the United States From Mills et al. (1991): “This filamentous red alga native to the Atlantic Coast was observed in Lake Erie in 1964 (Lin and Blum 1977). After this sighting, records for Lake Ontario (Damann 1979), Lake Michigan (Weik 1977), Lake Simcoe (Jackson 1985) and Lake Huron (Sheath 1987) were reported. It has become a major species of the littoral flora of these lakes, generally occupying the littoral zone with Cladophora and Ulothrix (Blum 1982). Earliest records of this algae in the basin, however, go back to the 1940s when Smith and Moyle (1944) found the alga in Lake Superior tributaries. Matthews (1932) found the alga in Quaker Run in the Allegheny drainage basin. Smith and 1 Moyle’s records must have not resulted in spreading populations since the alga was not known in Lake Superior as of 1987. Kishler and Taft (1970) were the most recent workers to refer to the records of Smith and Moyle (1944) and Matthews (1932).” From NOAA and USGS (2016): “Established where recorded except in Lake Superior. The distribution in Lake Simcoe is limited (Jackson 1985).” From Kipp et al. (2017): “Bangia atropurpurea was first recorded from Lake Erie in 1964. During the 1960s–1980s, it was recorded from Lake Huron, Lake Michigan, Lake Ontario, and Lake Simcoe (part of the Lake Ontario drainage). -

University of Lausanne, Switzerland A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Biology in the College of Arts and Sciences at the University of Central Florida Orlando, Florida Spring Term 2006 ABSTRACT Invasions of exotic species are one of the primary causes of biodiversity loss on our planet (National Research Council 1995). In the marine environment, all habitat types including estuaries, coral reefs, mud flats, and rocky intertidal shorelines have been impacted (e.g. Bertness et al. 2001). Recently, the topic of invasive species has caught the public’s attention. In particular, there is worldwide concern about the aquarium strain of the green alga Caulerpa taxifolia (Vahl) C. Agardh that was introduced to the Mediterranean Sea in 1984 from the Monaco Oceanographic Museum. -

Morphometric Analysis of Surface Utricles in Halimeda Tuna (Bryopsidales, Ulvophyceae) Reveals Variation in Their Size and Symmetry Within Individual Segments
S S symmetry Article Morphometric Analysis of Surface Utricles in Halimeda tuna (Bryopsidales, Ulvophyceae) Reveals Variation in Their Size and Symmetry within Individual Segments Jiri Neustupa * and Yvonne Nemcova Department of Botany, Faculty of Science, Charles University, Prague, 12801 Benatska 2, Czech Republic; [email protected] * Correspondence: [email protected] Received: 26 June 2020; Accepted: 20 July 2020; Published: 1 August 2020 Abstract: Calcifying marine green algae of genus Halimeda have siphonous thalli composed of repeated segments. Their outer surface is formed by laterally appressed peripheral utricles which often form a honeycomb structure, typically with varying degrees of asymmetry in the individual polygons. This study is focused on a morphometric analysis of the size and symmetry of these polygons in Mediterranean H. tuna. Asymmetry of surface utricles is studied using a continuous symmetry measure quantifying the deviation of polygons from perfect symmetry. In addition, the segment shapes are also captured by geometric morphometrics and compared to the utricle parameters. The area of surface utricles is proved to be strongly related to their position on segments, where utricles near the segment bases are considerably smaller than those located near the apical and lateral margins. Interestingly, this gradient is most pronounced in relatively large reniform segments. The polygons are most symmetric in the central parts of segments, with asymmetry uniformly increasing towards the segment margins. Mean utricle asymmetry is found to be unrelated to segment shapes. Systematic differences in utricle size across different positions might be related to morphogenetic patterns of segment development, and may also indicate possible small-scale variations in CaCO3 content within segments. -
Divergence Time Estimates and the Evolution of Major Lineages in The
www.nature.com/scientificreports OPEN Divergence time estimates and the evolution of major lineages in the florideophyte red algae Received: 31 March 2015 Eun Chan Yang1,2, Sung Min Boo3, Debashish Bhattacharya4, Gary W. Saunders5, Accepted: 19 January 2016 Andrew H. Knoll6, Suzanne Fredericq7, Louis Graf8 & Hwan Su Yoon8 Published: 19 February 2016 The Florideophyceae is the most abundant and taxonomically diverse class of red algae (Rhodophyta). However, many aspects of the systematics and divergence times of the group remain unresolved. Using a seven-gene concatenated dataset (nuclear EF2, LSU and SSU rRNAs, mitochondrial cox1, and plastid rbcL, psaA and psbA genes), we generated a robust phylogeny of red algae to provide an evolutionary timeline for florideophyte diversification. Our relaxed molecular clock analysis suggests that the Florideophyceae diverged approximately 943 (817–1,049) million years ago (Ma). The major divergences in this class involved the emergence of Hildenbrandiophycidae [ca. 781 (681–879) Ma], Nemaliophycidae [ca. 661 (597–736) Ma], Corallinophycidae [ca. 579 (543–617) Ma], and the split of Ahnfeltiophycidae and Rhodymeniophycidae [ca. 508 (442–580) Ma]. Within these clades, extant diversity reflects largely Phanerozoic diversification. Divergences within Florideophyceae were accompanied by evolutionary changes in the carposporophyte stage, leading to a successful strategy for maximizing spore production from each fertilization event. Our research provides robust estimates for the divergence times of major lineages within the Florideophyceae. This timeline was used to interpret the emergence of key morphological innovations that characterize these multicellular red algae. The Florideophyceae is the most taxon-rich red algal class, comprising 95% (6,752) of currently described species of Rhodophyta1 and possibly containing many more cryptic taxa2. -
