The effects of soil salinity and soil temperature, initial planting density, and removal of competition on survival and growth of outplanted species were examined. Germination response of four native wetland sedges to different water, salinity and temperature regimes was also investigated. Final survival exceeded 70 percent in four of the seven outplanted species. Soil salinity and soil temperature were negatively correlated with survival in only one species. Planting density and removal of competition had little effect on final survival and growth of outplanted species. Germination under experimental conditions exceeded 25 percent in only two of the four sedge species studied. Overall, seeds germinated to a higher percentage under lower temperatures and salinities than under higher temperatures and salinity levels. Water level had little effect on final germination percentage. xi, 113 leaves Mon, 01 Dec 2003 00:00:00 GMT http://hdl.handle.net/10125/7022 2003-12-01T00:00:00Z Brimacombe, Karen A http://hdl.handle.net/10125/7014 xii, 79 leaves Fri, 01 Aug 2003 00:00:00 GMT http://hdl.handle.net/10125/7014 2003-08-01T00:00:00Z Stephens, Sonia H http://hdl.handle.net/10125/6989 Experiments were conducted to determine the effects of soil disturbance on arbuscular mycorrhizal fungi root colonization and the growth of invasive and native Hawaiian plants, predicting higher AMP dependency in native species than invaders, with consequent decreased root colonization and plant growth with disturbance. Six species were grouped into 3 pairs (1 native: 1 invasive) and plants were grown in disturbed and undisturbed treatments in the greenhouse and field for 4/6 weeks. Root colonization, root length, stem and seedling height, leaf number, shoot and root biomass, and mycorrhizal dependency (MD) were measured. Root colonization was not affected by disturbance. Disturbance hindered growth of Acacia confusa, Acacia koa, Eidens pilosa, and Eidens sandvicensis. Data from only 1 pair (Acacia sp.) showed native plant MD greater than invader MD. The relationship between soil disturbance, root colonization, and plant growth may be species specific, and no native or invasive species trends were detected. vii, 76 leaves Thu, 01 May 2003 00:00:00 GMT http://hdl.handle.net/10125/6989 2003-05-01T00:00:00Z Weisenberger, Lauren A http://hdl.handle.net/10125/6909 Algal blooms on tropical reefs have become increasingly common over the last several decades. Reduced herbivore pressure, eutrophication and the introduction of exotic species have all been posited as factors that may drive these transitions in organism dominance. Several different types of algal blooms have been identified on reefs in the Hawaiian Islands including multispecies algal assemblages, monospecific algal blooms and seasonal or ephemeral blooms. This study sought to determine the causes of these different types of algal blooms by conducting both field and laboratory experiments and quantitative field assessments. In a factorial nutrient enrichment and herbivore exclusion experiment conducted for 6 months on the island of Hawaiʻi significant changes in algal biomass, community structure, sediment accumulation and mobile microinvertebrate abundance were found. Results of this study show that benthic reef communities can change rapidly in response to changes in both top down and bottom up factors. From field assessments across the main Hawaiian Islands a total of five (Acanthophora spicifera, Hypnea musciformis, Graci/aria salicornia, Kappaphycus spp. and Avranvillea amadelpha) species of nonindigenous algae can now be considered highly successful. Detailed studies on the ecology of select nonindigenous marine algae (NIMA) have identified particular concerns and highlighted the need for management action. In summary management of these invasive species will be challenging as a result of unique ecological and physiological strategies that each NIMA possesses. The ephemeral bloom forming native alga Cladophora sericea was studied during a bloom cycle during 2001 on the island of Maui. Results of ambient and sediment pore water sampling and algal physiological parameters suggest that ground water intrusion is occurring at this site and the alga appears to be utilizing this terrestrial based nutrient source. Upwelling and internal tides can naturally deliver nutrient rich water into coral reef ecosystems. In an area where internal tidal upwelling occurs in the Florida Keys, one of the most common benthic reef algae Halimeda tuna reflected patterns associated with natural nutrient enrichment. This study provides evidence that rich and highly productive benthic algae may thrive in deep water coral reef environments in response to naturally elevated nutrient conditions. xviii, 409 leaves Mon, 01 Dec 2003 00:00:00 GMT http://hdl.handle.net/10125/6909 2003-12-01T00:00:00Z Smith, Jennifer E
