“…The alternating dominance of diatoms and dinoflagellates is consistent with the general theme of Margalef's mandala (Margalef, 1983). A transition from diatom to dinoflagellate dominance coincided with a shift from P-to Si-limitation in both lakes, which agrees with the results of Escaravage et al (1996).…”

SUMMARY: Phytoplankton and physical-chemical parameters were investigated for the first time in the only natural hyperhaline marine lakes (salinity >40) along Croatia's Adriatic coast, Mala Solina and Velika Solina. Two periods were recognized during the one-year investigation: one euhaline-mesotrophic from December to May and one hyperhalineeutrophic from June to November. Nutrient limitation appears to have been important in defining the lakes' seasonal phytoplankton composition. Phosphate was most likely limiting from October to December, silicate from January to April, and nitrogen from June to September when nitrate was depleted. Diatoms were most abundant in November to January, when temperature and salinity were low and nitrate and ammonium were high. They collapsed in March when silicate was depleted. Amphora, Navicula, and other naviculoid diatoms were the most frequent genera. Nitzschia longissima was the most abundant species. Dinoflagellate dominance began in June in Mala Solina and in March in Velika Solina. It continued while temperature, salinity, phosphate, and silicate were high. Oxyrrhis marina was the most abundant dinoflagellate (3.2 × 10 6 cells L -1 ). Nanophytoplankton was the dominant size fraction. Chroococoid cyanobacteria were most abundant from May to October, reaching 2.9 × 10 7 cells L -1 in July. Both nanophytoplankton and small microphytoplankton, such as Oxyrrhis, Scrippsiella, and Tetraselmis, were most abundant under hyperhaline, N-depleted conditions. Toxic and harmful taxa (e.g. Alexandrium, Dinophysis), expanding in Mediterranean waters, were not recorded in the lakes.Keywords: phytoplankton, hydrography, nutrients, eutrophication, marine lakes, Adriatic Sea. RESUMEN: Respuesta del fitoplancton a la limitación de nutrientes y salinidad elevada en lagunas hipersalinas en el Adriático oriental. -El fitoplancton y diversos parámetros físico-químicos fueron estudiados por primera vez en dos lagunas hiperhalinas naturales (salinidad >40) de la costa de Croacia, Mala Solina y Velika Solina. El estudio se llevó a cabo durante 1 año, y pudieron distinguirse dos períodos: uno euhalino -mesotrófico, de diciembre a mayo, y el otro hiperhalino -eutrófico, de junio a noviembre. La limitación por nutrientes resultó ser un factor determinante para las variaciones estacionales en la composición del fitoplancton de las lagunas. El fosfato fue limitante de octubre a diciembre, el silicato de enero a abril, y el nitrógeno de junio a septiembre, una vez consumido el nitrato. Las diatomeas fueron especialmente abundantes entre noviembre y enero, cuando la temperatura y la salinidad eran bajas y la concentración de nitrato y amonio eran altas. El número de diatomeas disminuyó en marzo, tras el agotamiento del silicato. Amphora, Navicula y otras diatomeas naviculares fueron el género más frecuente, y Nitzschia longissima fue la especie más abundante. La dominancia de dinoflagelados comenzó en junio en Mala Solina y en marzo en Velika Solina, y se mantuvo mientras la temperatura, la salinidad, y la...

“…In contrast, waters in northern Chesapeake Bay had a light-phosphorus-nitrogen limitation, and in some cases silica limitation as well. Escaravage et al (1996) filled mesocosms with seawater from the Oosterschelde estuary, The Netherlands. Resource limitation in these mesocosm experiments alternated between nitrogen, phosphorus, and silica limitation (Escaravage et al 1996).…”

Abstract. We investigate biological mechanisms that generate oscillations and chaos in multispecies competition models. For this purpose, we use a competition model concerned with competition for abiotic essential resources. Because phytoplankton and plants consume quite a number of abiotic essential resources, the model is particularly relevant for phytoplankton communities and terrestrial vegetation. We show that the predicted dynamics depend crucially on the relationship between the resource requirements and the resource consumption characteristics of the species. More specifically, the model predicts that competition generates (1) stable coexistence if species consume most of the resources for which they have high requirements, (2) oscillations and chaos if species consume most of the resources for which they have intermediate requirements, and (3) competitive exclusion with a winner that depends on the initial conditions if species consume most of the resources for which they have low requirements. The theoretical predictions are compared with available data on resource utilization patterns of phytoplankton species.

“…Phytoplankton successions are known to be linked to and regulated by nutrients (e.g. Escaravage et al 1996, Estrada et al 2003, Lagus et al 2004). However, the succession process of phytoplankton community structures, and their relationship to nutrient stoichiometry after typhoon passage are still relatively unknown.…”

Climate change has the potential for intensification of typhoons, which will cause stronger effects on aquatic ecosystems in the future. The effect of typhoon Mawar (T0511), passing Manazuru Port located in the western part of Sagami Bay, Japan, was investigated from August to September 2005. Immediately after the passage of Mawar, photosynthetically available radiation showed high values, salinity decreased dramatically and nutrient concentrations (NO 2 +NO 3 , PO 4 and Si(OH) 4 ) increased. Skeletonema spp. and Leptocylindrus spp. were dominant after the passage of Mawar, and their succession was linked to the variability of the N/P ratio. Primary production was highest at 349 mg C m 3 day 1 three days after Mawar, and high assimilation numbers lasted for nine days. The integrated primary production during the nine days after Mawar was 2.1 10 3 mg C m 3 , which accounted for 7.2-9.1% of the annual primary production in the upper waters of Sagami Bay. The study confirms that enhanced primary production induced by episodic typhoon events in temperate coastal regions are significant, and should be considered in annual primary production estimates.
