Historical Changes in Macroalgal Communities in Hardangerfjord (Norway)
Marine Biology Research, 2014 Vol. 10, No. 3, 226Á240, http://dx.doi.org/10.1080/17451000.2013.810751 ORIGINAL ARTICLE Historical changes in macroalgal communities in Hardangerfjord (Norway) VIVIAN HUSA1*, HENNING STEEN2 & KJERSTI SJØTUN3 1Institute of Marine Research, Bergen, Norway, 2Institute of Marine Research, His, Norway, and 3University of Bergen, Department of Biology, Bergen, Norway Abstract Hardangerfjord is the second largest fjord in Norway and is situated on the southwest coast. During the last century the fjord has been influenced by a variety of anthropogenous activities such as industry, hydro-electrical power plants and since 1980 an increase in fish farming. This study was carried out in order to investigate whether changes in the macroalgal communities of Hardangerfjord have taken place since the 1950s. The macroalgal composition at a number of stations investigated in 2008Á2009 was compared to recordings from the same stations during the 1950s. While the distribution and abundance of dominant groups (fucoids, kelps) showed a high resilience when compared to recordings from the 1950s, some changes in the macroalgal communities in the fjord were evident. The present study showed higher species richness and a higher frequency of species with a warm-water affinity. Since the first part of the 1990s an increase in summer sea surface temperatures has taken place in the area, and the observed algal changes suggest a pronounced temperature effect on macroalgal communities. A number of red algal species was observed to protrude further into the fjord in the present study than in the 1950s, probably caused by altered salinity regime due to the electrical power industry. -

Department of Biology (Pdf)
Department of Biology 26 Summary The Department of Biology at the University of Louisiana at Lafayette took its current form in the late 1980s, with the merger of the Biology and Microbiology Departments. In Spring of 2019, the department has 28 professorial faculty members, 6 emeritus faculty members, and 7 instructors. Almost all professorial faculty members are active in research and serve as graduate faculty. Our graduate programs are also supported by 8 adjunct faculty members; their affiliations include the United States Geological Survey, the National Oceanographic and Atmospheric Administration, and the Smithsonian Institution. In this report, we summarize research accomplishments of our departmental faculty since 2013. The report is focused on our research strengths; however, faculty members have also been awarded considerable honors and funding for educational activities. We also briefly summarize the growth and size of our degree programs. Grant Productivity From 2013 through 2018, the Department of Biology has secured over 16 million dollars of new research funding (the total number of dollars associated with these grants, which are often multi- institutional, is considerably higher). Publications The faculty has a strong record of publication, with 279 papers published in peer-reviewed journals in the last 5 years. An additional 30 papers were published in conference proceedings or other edited volumes. Other Accomplishments Other notable accomplishments between 2013 and 2018 include faculty authorship of five books and edited volumes. Faculty members have served as editors, associate editors, or editorial board members for 21 different journals or as members of 34 society boards or grant review panels. They presented 107 of presentations as keynote addresses or invited seminars. -

Lyczkowski Thesis Advisor: Dr. Lee Karp-Boss An Abstract of the Thesis Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science (in Oceanography) December, 2012 Production of allelopathic chemicals by the toxic dinoflagellate Alexandrium fundyense is one suggested mechanism by which this relatively slow grower outcompetes other phytoplankton, particularly diatoms. Despite well documented allelopathic potential of Alexandrium spp., the potency is variable. -

The species has been in tufts, intercalary in loose upright filaments (Fig. 1, tentatively placed in Ralfsiaceae, but its ordinal b and c). It was first placed in the Ralfsiaceae, how- assignment has been uncertain. The molecular ever the ordinal position of the family was controver- phylogeny of brown algae based on concatenated sial at the time. Nakamura (1972) established the DNA sequences of seven chloroplast and order Ralfsiales to accommodate brown algal taxa mitochondrial gene sequences (atpB, psaA,psaB, having crustose thalli, an isomorphic life history, dis- psbA, psbC, rbcL, and cox1) of taxa covering most of coidal early development of the thallus, and each cell the orders revealed the most related phylogenetic containing a single, plate-shaped chloroplast without relationship of Z. leiomorpha to Nemoderma tingitanum pyrenoids. However, the validity of the order has (Nemodermatales) rather than Ralfsiaceae been questioned because a number of taxa exhibit- (Ralfsiales). -
2004 University of Connecticut Storrs, CT
Welcome Note and Information from the Co-Conveners We hope you will enjoy the NEAS 2004 meeting at the scenic Avery Point Campus of the University of Connecticut in Groton, CT. The last time that we assembled at The University of Connecticut was during the formative years of NEAS (12th Northeast Algal Symposium in 1973). Both NEAS and The University have come along way. These meetings will offer oral and poster presentations by students and faculty on a wide variety of phycological topics, as well as student poster and paper awards. We extend a warm welcome to all of our student members. The Executive Committee of NEAS has extended dormitory lodging at Project Oceanology gratis to all student members of the Society. We believe this shows NEAS members’ pride in and our commitment to our student members. This year we will be honoring Professor Arthur C. Mathieson as the Honorary Chair of the 43rd Northeast Algal Symposium. Art arrived with his wife, Myla, at the University of New Hampshire in 1965 from California. Art is a Professor of Botany and a Faculty in Residence at the Jackson Estuarine Laboratory of the University of New Hampshire. He received his Bachelor of Science and Master’s Degrees at the University of California, Los Angeles. In 1965 he received his doctoral degree from the University of British Columbia, Vancouver, Canada. Over a 43-year career Art has supervised many undergraduate and graduate students studying the ecology, systematics and mariculture of benthic marine algae. He has been an aquanaut-scientist for the Tektite II and also for the FLARE submersible programs. -

Smithsonian Contributions to Botany, number 34, 22 pages, 13 figures, 1976.-Six species of benthic marine algae (one Chlorophyta, two Phaeophyta, and three Rhodophyta) are newly reported from the Gulf of California, hfexico. Species of Halicystis, Sporochnus, Bonnemaisonia, Dudresnnya, and Sebdenia represent genera new to the Gulf, with the last being new to North America. The distribu~ionof twelve other species is extended. Two new nomenclatural combinations, Dasya bailloziviana var. nudicaulus and Dasya baillouviana var, stanfordiana, are proposed. The morphological variation of some species is discussed. Spermatangia of Dudresnnya colombiana, and tetrasporangia and spermatangia of Kallymenia pertusa are re- ported and described for the first time.

Based on 2 sampling campaigns on the Greek island of Lesvos in 2009 and 1 in northern Greece in 2012, this study provides first records of 3 intracellular eukaryotic pathogens infecting filamentous brown algae at these locations: Eury - chas ma dicksonii, Anisolpidium sphacellarum, and A. ectocarpii. Field and microscopic observa- tions of the 3 pathogens are complemented by the first E. dicksonii large subunit ribosomal RNA (LSU rRNA) gene sequence analyses of isolates from Lesvos and other parts of the world.
