Effects of experimental reduction of light availability on the seagrass Amphibolis griffithii
The response of the meadow-forming seagrass Amphibolis griffithii (Black) den Hartog to light reduction was examined over a 3 mo period and a subsequent 1 mo recovery period. Morphological and physiological variables were measured in meadows subjected to an average reduction in photosynthetic photon flux density (PPFD) of 88% relative to unshaded controls. Leaf biomass, leaf cluster density and...
متن کاملRecovery from the impact of light reduction on the seagrass Amphibolis griffithii, insights for dredging management.
A large-scale, manipulative experiment was conducted to examine the extent and rate of recovery of meadows of the temperate Australian seagrass, Amphibolis griffithii to different light-reduction scenarios typical of dredging operations, and to identify potential indicators of recovery from light reduction stress. Shade cloth was used to mimic different intensities, durations and start times of...
متن کاملSeagrass Canopy Photosynthetic Response Is a Function of Canopy Density and Light Environment: A Model for Amphibolis griffithii
A three-dimensional computer model of canopies of the seagrass Amphibolis griffithii was used to investigate the consequences of variations in canopy structure and benthic light environment on leaf-level photosynthetic saturation state. The model was constructed using empirical data of plant morphometrics from a previously conducted shading experiment and validated well to in-situ data on light...
متن کاملIn situ submarine pollination in the seagrass Amphibolis antarctica: research notes
Field observations, carried out as part of a hydrodynamic study on submarine pollen dispersal in dioeclous Arnphibol~s antarct~ca (Labill.) Sonder et Aschers. ex Aschers., showed that pollen release and subsequent pollinatlon events occur In stages over a period of approximately 1 mo, from late October to early December, a t 32" 16 'S, 115' 41' E on the coast of Western Australia. Examination o...
متن کاملFlow Regime: habitat and macroinvertebrate response
Introduction: Rivers are complex linear features, (Petts, 1994). Assessing habitat quality and composition has traditionally focused on reaches of 10s metres, recently interest has moved to the mesoscale (100s of metres) e.g. Paraseiwicz (2001); Maddock and Bird (1996). Assessment at the catchment scale is the ultimate goal, e.g. European Water Framework Directive (Bragg et al, 2005) and will p...
