Opis:: Nutrients are substances that are used by living organisms in the growth and survival of organisms. On the basis of this background, the aim of this study was to assess the concentration of nutrients (macro and micronutrients) and chlorophyll in the Menjer lake and to examine the relationship between nutrient concentration and algal biomass to identify the determinants of algal development in tropical lakes (Menjer Lake Wonosobo, Indonesia). The research was conducted using a survey method at Menjer Lake Wonosobo. Observations and sampling were carried out 3 times with intervals of 1 month at 7 locations in the photic zone. The concentrations of macronutrients and micronutrients in the Menjer Lake were spatially even in all locations and the temporally slightly increased concentrations were relatively the same during the measurement period. The Cu, NO2, Si, and Na macronutrients are the determining factors for algal blooming in Menjer Lake Wonosobo. The effect of Cu, NO2 and Si concentrations was inversely related to the algal abundance, while the Ca, Na and Mo concentrations were in line with the abundance of algae.

Opis:: A dinoflagellate identified as Prorocentrum dentatum, P. shikokuense or P. donghaiense is responsible of massive harmful events. Blooms of a species identified as P. shikokuense have been recently reported in the Mediterranean Sea, and an exotic origin, tentatively introduced by ballast waters from Asia, has been hypothesized. The molecular data based on the small-, large subunit, and internal transcriber spacers ribosomal RNA gene (SSU-, LSU-, ITS rRNA) sequences confirmed P. shikokuense in the Mediterranean Sea. The Mediterranean ribotype is identical to a subtropical North Atlantic ribotype, and with slight divergence from the numerous sequences from the Pacific Ocean. To revisit the relationship between P. shikokuense (=P. donghaiense) and P. obtusidens, we provide the first micrographs of P. dentatum and P. obtusidens, the latter collected from the type locality. Our observations indicate that P. dentatum, P. obtusidens, and P. shikokuense are three different species. Their diagnostic morphological characters are: Prorocentrum dentatum is 44–60 μm long, leaf-shaped, pointed and central posterior end, conspicuous anterior shoulder; P. obtusidens is 33–41 μm long, irregular parallelepiped, almost paralel valve margins, eccentric and pointed posterior end, moderate anterior shoulder; and P. shikokuense is <25 μm long, sunflower seed-shaped, round and centric posterior end, inconspicuous anterior shoulder.
