Abstract The recognition of broad biogeographic provinces provides an important framework for ecological and conservation biological research. Marine biologists have long recognized distinct in southern Australia, primarily on the basis qualitative differences intertidal species assemblages. Here we provide a priori test these traditional eastern (Peronian), western (Flindersian) south‐eastern (Maugean) provinces. Specifically, analyse distributional data approximately 1500 algal using newly...
Abstract Tasmania is an island state in south-eastern Australia that has a long and rich history of seaweed use, research, development. It cool-temperate system with 750 macroalgal species currently described. Tasmanian Aboriginal peoples have lived on this land for at least 40,000 years utilising as food, shelter, water carriers medicine, well ceremonial reasons. Modern taxonomic investigations began French naturalist Jacques-Julien Houtou de La Billardière 1791, there are 184 type...
Seaweed cultivation is gaining interest world-wide for both food and non-food applications. Global seaweed aquaculture production currently exceeds 32 Mt WW per annum but dominated (86% of total) by Asian countries. To meet future demand products, regions beyond Asia with potential are being explored. The goal this study was to assess the suitability native kelp Macrocystis pyrifera (Phaeophyceae, Laminariales), in Tasmania, south-eastern Australia. M. cultivated on seeded twine loops (1 – 5...
Climate-driven incursion of the long-spined sea urchin (Centrostephanus rodgersii) in eastern Tasmania has prompted calls for strong management intervention given urchins’ capacity to overgraze kelp beds and cause local collapse valuable reef fisheries. We examined effectiveness commercial divers culling C. rodgersii while undertaking otherwise normal fishing black-lip abalone (Haliotis rubra). Diver effort appears be driven by yield not opportunity maximise numbers urchins culled; greatest...
Abstract We found that an innovative nursery approach, where Lessonia corrugata seeded spools were cultivated by spinning to increase the water motion relative non-spinning spools, had higher growth in both and at-sea stages. Using this method, we compared of sporophytes on at different depths (1 m, 3 5 m) seasons (timing out-planting). Finally, vs. 3-m depth. In nursery, developed significantly faster than those spools: blade length was 4.6 2.5 cm, holdfast area 0.10 0.03 cm 2 for...
Abstract Kelp aquaculture is an emerging industry outside of Asia. To be successful, this requires a reliable production seedstock, the optimisation which greatly benefits from detailed physiological understanding microscopic life-cycle stages cultured species. This study investigated impact six zoospore densities (10–278 mm −2 ) on subsequent development Ecklonia radiata gametophytes and sporophytes. The results showed that germination rates sex ratio were unaffected by initial density, but...
Abstract Rapid ocean warming is affecting kelp forests globally. While the sporophyte life stage has been well studied for many species, microscopic stages of laminarian kelps have understudied, particularly regarding spatial and temporal variations in thermal tolerance their interaction. We investigated growth, survival, development, fertilization Ecklonia radiata gametophytes, derived from zoospores sampled two sites Tasmania, Australia, throughout a year, over temperature gradient...
Abstract Kelp forests provide vital ecosystem services such as carbon storage and cycling, understanding primary production dynamics regarding seasonal spatial variations is essential. We conducted surveys at three sites in southeast Tasmania, Australia, that had different levels of water motion, across four seasons to determine living biomass for kelp beds Lessonia corrugata (Order Laminariales). quantified blade growth, erosion rates, the variation population density estimated both net...
Abstract Community descriptions and distributions of the dominant subtidal macroalgae were recorded for D'Entrecasteaux Channel, Tasmania. These related to major environmental parameters light, water movement, substrate depth. Six communities recognized subjectively: ( 1 ) Durvillaea, 2 Phyllospora, 3 Macrocystis, 4 Ecklonia, 5) Fucoid (6) Seagrass ‐Cauterpa. divisions supported by cluster analysis data from Tinderbox, a site at northern end Channel. Detrended correspondence community...
Abstract Varying conditions that are encountered in power-plant substructures illustrated by discussing the problems arose construction of four power plants at Mexico City, Pekin, Ill., Cincinnati, Ohio, and Chicago, Ill. The first was on soil low bearing capacity, second water-bearing sand with a special cofferdam construction, third required deep foundation gravel, fourth clay foundation.
