Effects of ultraviolet and photosynthetically active radiation on five seagrass species (Page 1)

Effects of ultraviolet and photosynthetically active radiation on five seagrass species

Dawson SP and Dennison WC ·
1996

Five seagrass species [Halophila ovalis (R.Br) Hook. f., Halodule uninervis (Forsk.) Aschers., Zostera capricorni Aschers., Cymodocea serrulata (R.Br) Aschers. (ed.) and Syringodium isoetifolium (Aschers.) Dandy] from Moreton Bay, Australia, were grown under increased (+25%) and ambient levels of ultraviolet (UV) radiation and photosynthetically active radiation (PAR), and various morphological and physiological responses were examined.

Light intensity and the interactions between physiology, morphology and stable isotope ratios in five species of seagrass (Page 1)

Light intensity and the interactions between physiology, morphology and stable isotope ratios in five species of seagrass

Grice AM, Loneragan NR, and Dennison WC ·
1996

The effects of light intensity on stable isotope ratios, physiology and morphology of five seagrass species were investigated in an outdoor, light controlled experiment. Seagrasses were maintained in flowing seawater aquaria, with each seagrass species exposed to different light regimes (5, 15, 20, 30, 50, and 100% full sunlight) using shade screens.

Toward a national agenda for research in the coastal zone: Where are we?

Malone TC and Nemazie DA ·
1996

In response to the complex challenges of understanding and managing the effects of human activities on coastal ecosystems, the research establishment has produced a plethora of reports and implemented a bewildering array of government-sponsored research and monitoring programs that are not cost-effective on regional or national scales.

Latitudinal Variations in Mesozooplankton Grazing and Metabolism in the Central Tropical Pacific During the Us Jgofs Eqpac Study

Zhang X, Dam HG, White JR, and Roman MR ·
1995

Pigment ingestion rates by three size classes of mesozooplankton (200-500 mu m, 500-1000 mu m and 1000-2000 mu m) within the euphotic zone were measured during the Survey 1 (February/March) and Survey 2 (August/September) cruises of the 1992 United States Joint Global Ocean Flux Study (U.S. JGOFS) in the central equatorial Pacific (EqPac).
