In order to study the effect of temperature, irradiance, and salinity on the asexual reproduction of Caulerpa lentillifera, we conducted the indoor culture to study these factor effects on the regeneration of C. lentillifera, together with the measurement of photosynthetic parameters such as chlorophyll content, fluorescence characteristics, and rbcL(More)
Twenty-seven diterpenes of six chemical classes, including seven new diterpenes (1, 2, 6, 10, 11, 16, and 19), have been isolated from a collection of the brown alga Dictyota plectens from the South China Sea. The structures of the new diterpenes were elucidated by extensive spectroscopic analysis and by comparison with reported data. In the in vitro(More)
Science popularization level evaluation contributes to measuring science popularization effect. An evaluation method for science popularization level based on analytic hierarchy process (AHP) and grey relational analysis (GRA) is proposed in this paper. 6 first-level evaluation indexes including science popularization personnel, science popularization(More)
Part of the definition of Psammodiscus is that there is always a small pore and sometimes a rimoportula present on the valve centre. A new species Psammodiscus calceatus Tsuy.Watanabe, Nagumo & J. Tanaka is described, which lacks a central small pore. And the valves of P. nitidus were found that have two marginal rimoportulae. Living cell of P. nitidus(More)
Four new xenicanes, namely 4α-hydroxyisodictyohemiacetal (1), 4α-hydroxyisodictyoacetal (2), 13,18-diacetoxy-4-hydroxyisodictyo-19-al (3), and 4α-hydroxypachylactone (8), were isolated from a Chinese collection of the brown alga Dictyota plectens, along with four known analogues (4-7). The structures of the new diterpenes were determined by extensive(More)
The tropical to warm-temperate marine brown macroalgal genus Lobophora (Dictyotales, Phaeophyceae) recently drew attention because of its striking regional diversity. In this study we reassess Lobophora global species diversity, and species distributions, and explore how historical factors have shaped current diversity patterns. We applied a series of(More)
Many studies classifying Gracilaria species for the exploitation of agarophytes and the development of the agar industry were conducted before the prevalence of molecular tools, resulting in the description of many species based solely on their morphology. Gracilaria firma and G. changii are among the commercially important agarophytes from the western(More)
