Abstract:
An analysis of allele frequencies at five polymorphic enzyme loci of one mainland Australian and four Tasmanian populations of Austrocochlea constricta revealed that three readily distinguishable morphs were three species. These were identified as A. constricta, A. porcata and A. brevis sp. nov. In sympatric populations, two diagnostic loci separated A. constricta and A. brevis (PEP-A and AAT-2), two separated A. porcata and A. brevis (PEP-A and AAT-2), and one separated A. porcata and A. constricta (PEP-A). With the exception of the last, these loci were also diagnostic in allopatric populati

Abstract:
Patterns of genetic and morphological divergence were examined among Western Australian (Abrolhos Islands and Albany) and Tasmanian members of the highly variable 'Austrocochlea constricta' species complex. Analyses of allele frequencies at 13 enzyme loci confirmed the presence of three species within this complex in Tasmania, revealing additional diagnostic differences not previously detected. Where combinations of species sympatry were examined in Tasmania, seven diagnostic loci separated A. constricta and A. brevis, four separated A. porcata and A. brevis, and one separated A. porcata and A

Abstract:
Environmental Context. The pathways by which arsenic is accumulated, biotransformed and transferred in aquatic ecosystems are relatively unknown. Examination of whole marine ecosystems rather than individual organisms provides greater insights into the biogeochemical cycling of arsenic. Rocky intertidal zones, which have a high abundance of organisms but low ecological diversity, are an important marine habitat. This study examines the cycling of arsenic within intertidal ecosystems to further understand its distribution and transfer. Abstract. The present study reports total arsenic and arsen

Abstract:
Rock pools are unique and complex habitats in intertidal areas. Quantitative studies of assemblages in pools are few. Abundances and distributions of species in pools on a rock platform near Sydney (Australia) were sampled for two years. Pools of four different depths (5, 15, 30 and 40 cm deep) and up to four strata within each pool (0–5, 5–15, 15–30 and 30–40 cm, from the top of the pool) were sampled, replicated at four sites. The abundances and distributions of most species of plants and animals in pools did not differ between strata nor at different depths in the pools. Abundances of only

Abstract:
Zinc, copper and cadmium accumulation was measured in two herbivorous gastropod molluscs Austrocochlea constricta and Bembicium auratum from Lake Macquarie NSW an area with a history of trace metal pollution. The investigation consisted of three main parts. The first part examined the influence of organism mass and location within the Lake on whole body tissue metal concentrations. This part of the study also compared the distributions of tissue metal concentrations of populations from Lake Macquarie, a known polluted environment, with those of populations from Jervis Bay NSW, an unpolluted en
