Short-term variability of photosynthesis in natural marine phytoplankton populations
Harmonic regression analysis has been used to determine the short-term variability in the photosynthetic rate (mgC/mg chlorophyll a/h) of phytoplankton in three inlets of Japan. In natural water without large zoo...

Influence of termite treatment in the home on the chlordane concentration in human milk
An increase of chlordane contamination in humans after termite treatment of their homes was investigated by analyzing human milk samples of breast-feeding women. Chlordane in human milk was analyzed by gas chr...

Effects of hypobaric hypoxia on the oxidative capacity of the extensor digitorum longus motor units in the rat
The fiber number, fiber type distribution, and succinate dehydrogenase activity were investigated from the fast-twitch extensor digitorum longus muscle of male rats exposed to 7 weeks of hypobaric hypoxia. The...

Ecological impact of a fresh-water “reef kill” in Kaneohe Bay, Oahu, Hawaii
Storm floods on the night of December 31, 1987 reduced salinity to 15‰ in the surface waters of Kaneohe Bay, resulting in massive mortality of coral reef organisms in shallow water. A spectacular phytoplankton...

Modeling of spring bloom in the western subarctic Pacific (off Japan) with observed vertical density structure
Effects of vertical stability on spring blooms of phytoplankton were investigated for the western subarctic Pacific ocean using a one-dimensional (depth) ecosystem model. In the model, vertical stability was e...

Characterization of a hemichordate fork head/HNF-3 gene expression
Based on anatomical and developmental similarities, hemichordates are thought to be most closely related to chordates. However, so far very few developmental genes have been characterized from hemichordates. T...

Characteristics of TEC variations observed at Chofu for geomagnetic storms
Since the middle of 1996, we have made a routine observation of TEC using GPS in Chofu (35.65°N, 139.54°E), Tokyo. We examine in this paper the relationship between the perturbation components of TEC and geoma...

Growth of zooxanthellae in culture with two nitrogen sources
Physiological characteristics of zooxanthellae were examined under nutrient-saturated conditions created by mixing ammonium (15NH4) with nitrate (15NO3) to give 0.88 mM total nitrogen. Growth rate varied with th...

Consequences of the neural network investigation for Dst-AL relationship
Several recent studies have suggested that most of the Dst main phase variations and of the AL variations similarly respond to a certain type of solar wind condition although the processes are independent of each...

Rapid response to changing light environments of the calanoid copepod Calanus sinicus
Calanus sinicus is a large calanoid copepod and a dominant species in the coastal waters of Japan. During a research cruise in Sagami Bay on 18 June 1996, we found C. sinicus performing an “unusual” diel vertica...
