The effects of temperature, salinity and irradiance on the growth harmful red tide dinoflagellate Cochlodinium polykrikoides were examined in laboratory. From 60 different combinations temperature (10–30°C) (10–40) under saturated irradiance, C. exhibited its maximum specific rate 0.41 day−1 at a combination 25°C 34. Optimum rates >0.3 observed temperatures ranging from 21 to 26°C salinities 30 36. organism did not grow ≤10°C only grew >30 if was >15°C. It able 15 30°C 20 These values...
The rising demand of ecosystem services, due to the increasing human population in coastal areas, and subsequent need secure healthy sustainable seas constitute a major challenge for marine ecosystems management. In addition, global anthropogenic changes have transformed realm, thereby challenging health services necessary welfare. These opened ecological space opportunistic organisms, such as jellyfish, resulting ecosystem-wide economic implications that threaten services. Here, we used...
We investigated long-term variations in the dominant phytoplankton groups with improvements water quality over 11 years Yeongil Bay on southeastern coast of Korea. River discharge declined during study period but TN from river remained stable, indicating input enriched nutrients to bay was fairly consistent. NH 4 + levels decreased a decrease POSCO industrial complex. While region characterized by P-limited and deficient environment, cryptophytes dominated intensified P-limitations. The...
The prolonged rainy season in 2020 was classified as the second-largest rainfall event since 1961. In this study, we conducted a survey to assess fluctuations zooplankton community structure of northern East China Sea (nECS) after August 2020. We examined 24 stations and observed several environmental factors, including water temperature, salinity, chlorophyll-a concentration, suspended particulate matter (SPM), phytoplankton density. Zooplankton samples were collected from 12 using MOCNESS...
Brackish-water calanoid copepods, defined as those predominantly inhabiting oligo- and mesohaline waters, were investigated at 45 rivers in western Japan during 2006–2009 to review their faunas and, for comparison, 4 of Korea 2006. Eight species (Acartia ohtsukai, A. sinjiensis, tsuensis, Pseudodiaptomus inopinus, P. ishigakiensis, Sinocalanus sinensis, S. tenellus Tortanus derjugini) identified brackish-water copepods from Japan. Among them, inopinus was most often collected; it occurred 38...
A new species, Pseudodiaptomus koreanus sp. nov. (Calanoida, Pseudodiaptomidae), which has so far been identified as P. inopinus Burckhardt, 1913, is described from Korean estuaries. This species differs in the broad and short posterior process of female genital flap, rounded posteriocentral projection between gonopores, presence a posterodorsal spinule on fifth pediger male, row fine ventral spinules male second urosomite. The also distinguishable nansei Sakaguchi Ueda, 2010 by along...
Microcystis aeruginosa , a freshwater microalga, is capable of producing and accumulating different types sugars in its biomass which make it good feedstock for bioethanol production. Present study aims to investigate the effect factors increasing growth rate carbohydrates productivity M. . MF media (modified BG11 media) additional ingredients such as aminolevulinic acid (2 mM), lysine (2.28 alanine (1 Naphthalene acetic mM) cytokine promoted sugar contents. Salmonella showed...
서 론 해양의 기초생산자인 식물플랑크톤은 태양에너지를 이용 하여 무기물로부터 유기물을 합성한다.식물플랑크톤의 광 합성과 성장은 빛의 성질에 따라 크게 영향을 받게 되며,
울진 동해바다목장 해역의 식물플랑크톤 군집의 시·공간적 분포특성을 파악하기 위하여 2008년 4월부터 11월까지 9개 정점의 표층과 10 m 수심에서 4회 현장조사를 실시하였다. 출현한 식물플랑크톤은 67속 123종으로 다양하였다. 군집은 규조류가 60.5%, 와편모조류가 34.6%를 차지하였고, 가을에 가장 많은 종이 출현하였다. 현존량은 9월 1.8 × 10SUP3/SUP cells·L-1에서 4월 2.4 10SUP5/SUP cells·LSUP-1/SUP의 범위로 연평균 4.8 10SUP4/SUP cells·LSUP-1/SUP로 낮았다. 최우점 및 차우점종은 소형인 Thalassiosira sp., Pseudo-nitzschia pungens. 6월은 Leptocylindrus danicus, Guinardia striata, 9월은 Cheatoceros cirvisetus, Ch. decipiens 그리고 11월은 Skeletonema costatum -ls (like...
Paralytic shellfish toxin contents and profiles were investigated using toxin-producing dinoflagellate Gymnodinium catenatum strains isolated from Inokushi Bay during the March July 2002 outbreak.The strains, which 72 bloom water, exhibited average growth rates of 0.25 divisions day -1 due to sub-optimal temperature.The content was 321 f mole cell - 1 .The principal C1+2 (79.8 mole%) GTX 5+6 (18.0 mole%), minor components characterized as 2+3, dcGTX2+3, neoSTX+STX.Interestingly, 7 clearly...
The Nemopilema nomurai a very large jellyfish that has been found in the East China Sea and is now are migrating to Korea Japan. To investigate occurrence of N. based on changing marine environment Sea, we conducted field survey early summer from 2006-2008. We observed using CTD FMT bottom trawling. caught most 2007 fewest 2008 factors influencing its more sensitive temperature than salinity. Large quantities with small bell diameter were individuals significant 2008. This appeared which...
