A total of 180 algal and 36 seagrass records, exclusively collected from the Andaman Sea area off the coast of Thailand, are deposited in the Reference Collection of the Phuket Marine Biological Center (PMBC). The collection consists of 113 algal species representing 37 families and 10 seagrass spec...

For livers of lake trout from three Great Lakes sites, the 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) equivalent concentrations (TEQs) were determined in four ways. Bioassay-derived (BD) TEQs were measured with rat (H4IIE) and rainbow trout (RTL-W 1) cell lines, and chemistry-derived (CD) TEQs were ...

The acute and chronic effects of secondary-treated effluent from a New Zealand pulp and paper mill were assessed using both long-term adult and early life stage (ELS) laboratory exposures of rainbow trout. The relative impact of maternal exposure versus ELS exposure was assessed by a comparison of d...

We have previously reported that neonatal rats display enhanced sensitivity to domoic acid relative to adults, and that perinatal injections of low doses of domoic acid alter early associational learning in the newborn rat. The current study was designed to further investigate the effects of low dos...

A biological expedition jointly organized by the National University of Singapore-Raftics Museum of Biodiversity Research and the Indonesian Institute of Sciences collected marine algae and seagrasses in the Anambas and Natuna Islands (Kepulauan Anambas and Kepulauan Natuna), Indonesia. A total of 2...

An outbreak of food poisoning in Canada during autumn 1987 was traced to cultured blue mussels (Mytilus edulis ) from the Cardigan Bay region of eastern Prince Edward Island (P.E.I.). The toxin, identified as domoic acid, had not previously been found in any shellfish and this outbreak represents th...

Japanese medaka (Oryzias latipes) were exposed to octylphenol, a known oestrogen agonist, to assess its effects on reproductive success. Male and female medaka were exposed to nominal concentrations of 10, 25, 50, and 100 micro g/litre octylphenol from 1 day after hatching to 6 months after hatching...

In this study, the immune reactions of rainbow trout (Oncorhynchus mykiss) were examined, after exposure to 10, 30 and 70% of tertiary-treated municipal sewage effluent for 27 days. Exposures were conducted concurrently with and without an immune challenge using intraperitoneal injections of inactiv...

While it is known that glutamate is critical to CNS development and function, less is known about the role of kainate receptors, a subclass of ionotropic glutamate receptors, during ontogeny. This is especially true with respect to the emergence and expression of behaviour. It is also known that the...

In order to test the viability of oil sands aquatic reclamation techniques, yellow perch (Perca flavescens) were stocked into three experimental ponds. Pond substrates consisted of either oil sands fine tailings or clay and lean oil sands deposited by the mining operations. Yellow perch were stocked...

Japanese medaka (Oryzias latipes) were exposed to concentrations of 0.01, 0.10, or 1.0 micro g/litre of the pesticide endosulfan for 24 h beginning either 4-6 h postfertilization or 4-6 h posthatch to determine effects on hatching time, growth, mobility, foraging ability, and reproduction. Eggs expo...

A modified mathematical model based on the concept of generative centres is proposed to describe organogenesis in young leaf primordia of Murraya paniculata. Measurements of specific parameters on leaf primordia at different stages of development support the basic assumptions of the model. These ass...

Previous studies on palm phyllotaxis deal mainly with the mature trunk. The goals of this study are (i) to determine the relationship between the number of parastichies, the divergence angle, and the plastochrone ratio at the level of the shoot apical meristem; (ii) to examine whether there are fluc...

This study examined the hypothesis that chlorine dioxide bleaching used in pulp and paper production causes the formation of reproductive-endocrine disrupting compounds from plant sterols. This was tested by conducting a laboratory simulation of the chlorine dioxide oxidation of two plant sterols, b...
