Limited Effects of Grazer Exclusion on the Epiphytes of Posidonia Sinuosa
Aquatic Botany 78 (2004) 3–14 Limited effects of grazer exclusion on the epiphytes of Posidonia sinuosa in South Australia Dominic Keuskamp∗ School of Biological Sciences, Flinders University of South Australia, GPO Box 2100, Adelaide SA 5001, Australia Received 8 August 2002; received in revised form 10 July 2003; accepted 22 August 2003 Abstract The role of grazing in regulating the abundance and biomass of epiphytes of the seagrass Posidonia sinuosa Cambridge et Kuo was investigated at an oligotrophic site in lower Spencer Gulf, South Australia. Prosobranch gastropods >7 mm in size were excluded from 0.25 m2 plots of seagrass for 3 months with four steel mesh cages, compared with four partial cages used to control for cage artefacts, and also four uncaged control plots. Abundances of epiphytic algae, invertebrates and epiphytic mass (DW, AFDW and calcium carbonate) were recorded regularly. The indirect effect of grazer exclusion on seagrass leaf mortality (necrosis) was also measured. Grazing effects on the epiphytic assemblage were detected despite some cage artefacts. Filamentous algal abundance and epiphytic biomass (AFDW) increased in response to grazer exclusion. Caging per se reduced crustose coralline algal cover and calcium carbonate during the experimental period but, after 3 months, no artefact or treatment effect was discernible. Abundances of invertebrate taxa were little affected by grazer exclusion although caging per se reduced the density of spirorbid polychaetes. Grazer exclusion did not affect seagrass necrosis. In comparison with similar studies and given the duration of exclusion, the sum of treatment effects on epiphytes and seagrass was small. Rather, the role of epiphyte grazing in this nutrient-poor area appears to be limited to the maintenance of an epiphytic assemblage that is free of filamentous algae and dominated by crustose corallines. -

HÉRA ZOLTÁN H-7400 Kaposvár Tamási Áron utca 9, Hungary, e-mail:[email protected] HÉRA Z.: Enrichment of the malacological (Mollusca) collection in Somogy County Museum I. Abstract: A small but old collection of mollusc from Dr. Wiesinger's legacy got to the collection of the Natural History Department of Somogy County Museum. Altogether 2600 items, 18000 specimens can be found in the revised collection, the bigger part of the collection (Tolnai's coll.) date from the first part of 20th century. Now the author published the date of Tolnai's collection in this paper. There are collection materials not only from Dr. Tolnai but also his famous contemporary malacologists: Streda R., H. Barthelmes, Geyer, Hässlein, W. Klemm, Schlickum, W. R., Jaeckel, S., Modell, H. Waldén, H. W.

Monophyly, Distance and Character–Based Multigene Barcoding Reveal Extraordinary Cryptic Diversity in Nassarius: a Complex and Dangerous Community
Monophyly, Distance and Character–Based Multigene Barcoding Reveal Extraordinary Cryptic Diversity in Nassarius: A Complex and Dangerous Community Shanmei Zou1,QiLi2*, Lingfeng Kong3 1 Key Laboratory of Mariculture Ministry of Education, Ocean University of China, Qingdao, China, 2 Key Laboratory of Mariculture Ministry of Education, Ocean University of China, Qingdao, China, 3 Key Laboratory of Mariculture Ministry of Education, Ocean University of China, Qingdao, China Abstract Background: Correct identification and cryptic biodiversity revelation for marine organisms are pressing since the marine life is important in maintaining the balance of ecological system and is facing the problem of biodiversity crisis or food safety. DNA barcoding has been proved successful to provide resolution beyond the boundaries of morphological information. Nassarius, the common mudsnail, plays an important role in marine environment and has problem in food safety, but the classification of it is quite confused because of the complex morphological diversity. Methodology/Principal Findings: Here we report a comprehensive barcoding analysis of 22 Nassarius species. We integrated the mitochondrial and nuclear sequences and the morphological characters to determine 13 Nassarius species studied and reveal four cryptic species and one pair synonyms. Distance, monophyly, and character–based barcoding methods were employed. Conclusions/Significance: Such successful identification and unexpected cryptic discovery is significant for Nassarius in food safety and species conversation and remind us to pay more attention to the hidden cryptic biodiversity ignored in marine life. Distance, monophyly, and character–based barcoding methods are all very helpful in identification but the character-based method shows some advantages.

The recent Expression of Interest process for Parks Victoria manages Point Nepean National Park development of the Quarantine Station highlights including the Point Nepean Quarantine Station, the planning challenges and the delicate balance on behalf of the government and the Victorian between conservation, appropriate development community. Protection of this significant piece and adaptive reuse of its heritage buildings. of Australia’s heritage is of primary importance to Parks Victoria, to ensure that its beauty, heritage On behalf of the Victorian Government, Parks Victoria and stories are conserved for future generations is undertaking three tasks: to enjoy. 1. Re-engaging with the community and stakeholders This paper outlines the master planning principles to re-affirm their aspirations for Point Nepean that Parks Victoria understands to be current and 2. Expressing those aspirations in a renewed master relevant. It summarises what we have heard during plan for public comment consultation so far and seeks your input. 3. Finalising a master plan that the government will This document is structured as follows: use as the clear and unequivocal parameters for • Purpose future management and development. • Background Over a number of years, the community, stakeholders, local businesses and industry have contributed generous • Draft master plan: key elements amounts of knowledge, time and energy which Parks • Engagement Victoria has captured in the Point Nepean National Park Master Plan. -

NATIONAL PARKS ACT ANNUAL REPORT 2019–2020 Traditional Owner Acknowledgement Victoria’s network of parks and reserves form the core of Aboriginal cultural landscapes, which have been modified over many thousands of years of occupation. They are reflections of how Aboriginal people engaged with their world and experienced their surroundings and are the product of thousands of generations of economic activity, material culture and settlement patterns. The landscapes we see today are influenced by the skills, knowledge and activities of Aboriginal land managers. Parks Victoria acknowledges the Traditional Owners of these cultural landscapes, recognising their continuing connection to Victoria’s parks and reserves and their ongoing role in caring for Country.

Submission Re Proposed Cooloola World Heritage Area Boundary
Nearshore Marine Biodiversity of the Sunshine Coast, South-East Queensland: Inventory of molluscs, corals and fishes July 2010 Photo courtesy Ian Banks Baseline Survey Report to the Noosa Integrated Catchment Association, September 2010 Lyndon DeVantier, David Williamson and Richard Willan Executive Summary Nearshore reef-associated fauna were surveyed at 14 sites at seven locations on the Sunshine Coast in July 2010. The sites were located offshore from Noosa in the north to Caloundra in the south. The species composition and abundance of corals and fishes and ecological condition of the sites were recorded using standard methods of rapid ecological assessment. A comprehensive list of molluscs was compiled from personal observations, the published literature, verifiable unpublished reports, and photographs. Photographic records of other conspicuous macro-fauna, including turtles, sponges, echinoderms and crustaceans, were also made anecdotally. The results of the survey are briefly summarized below. 1. Totals of 105 species of reef-building corals, 222 species of fish and 835 species of molluscs were compiled. Thirty-nine genera of soft corals, sea fans, anemones and corallimorpharians were also recorded. An additional 17 reef- building coral species have been reported from the Sunshine Coast in previous publications and one additional species was identified from a photo collection. 2. Of the 835 mollusc species listed, 710 species could be assigned specific names. Some of those not assigned specific status are new to science, not yet formally described. 3. Almost 10 % (81 species) of the molluscan fauna are considered endemic to the broader bioregion, their known distribution ranges restricted to the temperate/tropical overlap section of the eastern Australian coast (Central Eastern Shelf Transition).
