© 2018, Springer Nature B.V. The combined effects of irradiance and temperature on photosystem II (PSII) photochemical efficiency were investigated in the microscopic sporophyte and macroscopic gametophyte stages of the cultivated red algae Pyropi...

© 2018, Springer Nature B.V. The effect of photosynthetically active radiation (PAR) and temperature on the photosynthesis of a temperate Japanese edible brown alga, Cladosiphon umezakii (Chordariaceae, Ectocarpales), from Honshu Island, Japan, wa...

© 2019 Japanese Society of Phycology The effects of irradiance, temperature, thermal- and chilling-light sensitivities on the photosynthesis of a temperate alga, Sargassum macrocarpum (Fucales) were determined by a pulse amplitude modulation (PAM)...

© 2018 International Phycological Society. The effect of photosynthetically active radiation (PAR) and temperature on the photosynthesis of an endangered Japanese freshwater red alga, Thorea okadae (Thoreaceae, Thoreales), was determined by using ...

The photosynthetic characteristics of five Sargassum species (Fucales): S. piluliferum, S. patens, S. fusiforme, S. crispifolium and S. alternato-pinnatum, were determined over a range of temperatures (10-36°C) by a dissolved oxygen meter and a pu...

The present study was designed to develop a technique for crossing and to gain insight into how sexual reproduction contributes to the maintenance of local populations of Ulva compressa L. To examine the durations of gamete motility and conjugatio...

In coastal marine ecosystems, the environmental stress model (ESM) predicts that the central measures (i.e.,the mean or median) of species richness are highest at intermediate stresses (e.g.,intermediate levels of light and wave exposure). It is n...

Environmental changes influence foraging behavior for most animals. Dolphinfish, Coryphaena hippurus, are epipelagic predators and have a cosmopolitan tropical to warm-temperate (>20°C) distribution. We simultaneously obtained the ambient temperat...

We determined the relationship between the residence times of water within the canopy of the intertidal macroalgae, Sargassum fusiforme (Harvey) Setchell to the energy caused by hydrodynamic mixing. We measured the residence times (t) of fluoresce...

The nutrient supply rates within the canopy of the economically important red algal species, Eucheuma serra J. Agardh were determined experimentally in a recirculating flow-chamber. A single individual was placed in the working section of the 2000...

Wave exposure is one of the fundamental variables of the coastal environment and many coastal processes are affected by waves and wave-induced water motion. Directly or indirectly, waves affect the lives of many coastal macroalgae and seagrasses. ...

Hydrodynamic models of mass transport assume that diffusive processes next to the surface limit transport and that there are no biological and chemical processes that control the supply and demand of the scalar. The validity of these assumptions w...

The biology of aquatic organisms determines the maximum rates of physiological processes, but the mass transport of nutrients determines the nominal rates at which these processes occur. Maximum O2 flux (P max) at 17.1 mmol m-3 CO2 was higher for ...

© 2014, by the Association for the Sciences of Limnology and Oceanography. The mass transfer of scalar quantities (e.g., O2 and nutrients) in aquatic environments is an important and complex process involving diffusion and advection. In a flowing ...

The combined effects of water velocity (U) and dissolved inorganic carbon (DIC) concentration on photosynthesis rates of Vallisneria americana were investigated. The net photosynthesis rate or O2 flux (J obs) from leaves increased with U from 0.20...

The seasonal change in biomass and morphology of Sargassum duplicatum Bory (Fucales, Phaeophyceae) was examined during January 2002 to May 2003 at Bandokorobana Park, Kagoshima, Japan, located on the southern coast of the Satsuma Peninsula. A 100-...

The effects of temperature (20, 24 and 28 °C) and irradiance (15 and 40 μmol photon m-2 s-1) on the nitrate and ammonium uptake rates of the subtropical red alga, Laurencia brongniartii, were investigated to prepare for tank cultivation. Nitrate u...

Laurencia brongniartii is usually found at depths below 4 m, but can be found in shallow subtidal areas in crevices and on the walls of a coral reef in Amami Oshima Island, Kagoshima Prefecture, Japan, where irradiances were significantly lower th...

The seasonal change in size of Laurencia brongniartii was observed for the year 2002 at Banshobana Park, Satsuma Peninsula and Tsuchihama Beach, Amami Oshima, both in Kagoshima Prefecture, Japan. Additionally, the vertical distribution of this spe...
