The Effect Of Leaf Movement On Algal Epiphytes In Seagrass Meadows, T. R. Reid
The Effect Of Leaf Movement On Algal Epiphytes In Seagrass Meadows, T. R. Reid
Theses : Honours
Artificial seagrass units were used to determine whether seagrass leaf movement influences the biomass, species richness and composition of epiphytic macroalgae on the leaves of seagrasses, and whether the influence of leaf movement is altered by the degree of exposure to water movement and to depth. The influence of leaf movement on epiphytic biomass is important from an environmental management perspective, as there is the potential for epiphytic productivity to be underestimated if leaf movement is reducing the standing crop of epiphytes on seagrass leaves. Two forms of artificial seagrass units were used in three experiments to achieve these objectives; …
Biogeography Of A Changing Landscape: Pipidinny Swamp, Yanchep National Park Western Australia, Bradley W. Boucher
Biogeography Of A Changing Landscape: Pipidinny Swamp, Yanchep National Park Western Australia, Bradley W. Boucher
Theses : Honours
The resources of Pipidinny Swamp were utilised by the Nyoongar Aboriginal people for possibly 40,000 years. Since the late 1800s, the resources of Pipidinny Swamp were used by non-Indigenous settlers. More recently, the wetland was incorporated in the Yanchep National Park in 1991.This study sought to reconstruct the changes to the natural and cultural environments within the wetland to provide background knowledge for the management board of the Park. Field investigations abo demonstrated the dynamic state of the wetland over a six-month period between low water (Feb-Apr) and high water (Aug-Oct) by monitoring the groundwater system, the vegetation system, and …
