Soviet Union fishing fleets found Patagonian toothfish in 1985 off the Kerguelen Islands in the Southern Ocean. In a few short years, toothfish became heavily fished and the viability of the fishery was put in question. This pressure largely arose from illegal, unreported, and unregulated (IUU) fishing that undermined fisheries management by coastal states and the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) Commission. The International Southern Oceans Longline Fisheries Information Clearing House (ISOFISH), based in Hobart, Tasmania, Australia, raised awareness about IUU fishing among governments, fishers, and the community. This article presents a case study of ISOFISH and the influence this nongovernment organization coalition exerted on the international community, including the deep-sea fishing in...

Bushfires pose a significant threat to lives and property. Fire management authorities aim to minimise this threat by employing risk management procedures. This paper proposes a process of implementing, in a Geographic Information System environment, contemporary integrated approaches to bushfire risk analysis that incorporate the dynamic effects of bushfires. The system is illustrated with a case study combining ignition, fire behaviour and fire propagation models with climate, fuel, terrain, historical ignition and asset data from Hobart, Tasmania, and its surroundings. Many of the implementation issues involved with dynamic risk modelling are resolved, such as increasing processing efficiency and quantifying probabilities using historical data. A raster-based, risk-specific bushfire simulation system is created, using a new, efficie...
The Gunns Plains karst comprises an area of Ordovician limestone, now largely coverted to
farmland, that lies in the Leven River Valley about 30 minutes drive from Ulverstone on
Tasmania's north western coastline. A commercial tourist cave has been in operation in the
area for many years. In recent years numerous previously unknown caves have been
documented by members of the Savage River Caving Club; overviews of the karst have been
compiled by Kiernan
For pest management of introduced marine species to succeed, a thorough understanding of reproductive patterns is essential. Undaria pinnatifida is an invasive macroalga that has been introduced into at least ten countries. Reproductive phenological studies in Tasmania, Australia were undertaken to provide much-needed quantitative information to support pest management. Zoospore release of U. pinnatifida, an annual kelp, was limited to the larger size-classes of sporophytes (> 55 cm length) for most of the growing season, with the proportion of mature sporophytes increasing towards the end of the season. Small sporophytes with mature sporophylls were not observed until late in the growing season, i.e., after November. The maximum zoospore release of U. pinnatifida was 62 x 103 zoospores cm-2 sporophyll tissue h-1, corresponding to a m...
Human leucocyte antigen (HLA)-DRB1*15 is
associated with predisposition to multiple sclerosis (MS),
although conjecture surrounds the possible involvement of
an alternate risk locus in the class I region of the HLA
complex. We have shown previously that an alternate MS
risk allele(s) may be encompassed by the telomerically
extended DRB1*15 haplotype, and here, we have attempted
to map the putative variant.
Following mass mortalities of sea urchins, Strongylocentrotus droebachiensis (Mueller), in the rocky subtidal of the Atlantic coast of Nova Scotia, dense seaweed beds dominated by the canopy-forming kelp Laminaria longicruris de la Pylaie developed for the first time in several years. The numerically abundant grazers in the seaweed beds when sea urchins were rare were the mesogastropod Lacuna vincta (Montagu), the limpet Notoacmaea testudinalis (Mueller), and the chiton Tonicella rubra (Linne). The limpet and chiton are unable to graze the macroscopic sporophytes of Laminaria, and a manipulation experiment showed that they have no significant effect on the recruitment of this kelp. In contrast, Lacuna grazes the macroscopic sporophyte and several of its population characteristics suggested that it might be a potentially important graze...
Comparisons of hydrographic conditions in the North and South Pacific Oceans in the 1960s and 1985–94 have been made along five World Ocean Circulation Experiment sections. Below the seasonal mixed layer, statistically significant temporal differences in salinity and temperature have been detected in the water masses that occur in the upper 2000 dbar of the water column. These water mass property differences have been used to estimate the freshwater and heat storage trends in the Pacific over the study period. Along 248N, 108N, and 178S, where either North Pacific Intermediate Water or Antarctic Intermediate Water is present, the upper waters have increased in salinity, while the intermediate and deep waters have decreased in salinity. Although the depthintegrated salinity changes observed along these sections are small, the regional r...
