Bachelor of Science (Honours) thesis, Discipline of Geography and Spatial Sciences, School of Land and Food, University of Tasmania. Page iii Abstract Saltmarshes are an intriguing ecotone representing the transition between the marine and terrestrial environments. Much is understood in terms of zonation and vegetation communities in saltmarshes, however considerably less is understood about their edaphic factors. In Australian saltmarshes, terrestrial arthropod fauna and factors that determine invertebrate assemblages are largely unknown. The aim of this study was to understand the factors that influence the presence of epigeal spiders and beetles in a coastal saltmarsh. The chosen site at Long Point, a saltmarsh on Tasmania’s east coast, included adjacent woodland which enabled expansion of the study to incorporate a full environmental gradient. Moisture, salinity and pH gradients were analysed alongside vegetation community structure. During the 12 month study period 5 606 spiders (37 taxa) and 1 165 beetles (84 taxa) were caught in 141 pitfall traps. Indicator species (spider and beetle) were identified for each vegetation community within the saltmarsh zone and adjacent woodland zone. Spiders and beetles reacted in a similar fashion to edaphic factors and vegetation species. However, the sequential order of importance for spiders was moisture, salinity and vegetation, whereas, the response order for beetles was moisture, vegetation and salinity. Further investigation into the interaction between saltmarsh vegetation species and spider and beetle species will assist in our endeavours to understand the loss or gain of arthropod species due to climate change and sea-level rise. Key words Saltmarsh, landscape features, edaphic factors, vegetation communities, invertebrate assemblages, spiders, beetles, Tasmania Page iv Acknowledgments A project of this scale would not have been possible without the help of many people, and I gratefully acknowledge their assistance. Access to a very special research site was granted by the Tasmanian Land Conservancy with John and Jane Cotton permitting vehicular access. Stuart MacDonald, Colin Sumner, Ross Lucas, Jon Traynor, Christian Mackay and Mel Bottrill gave valuable assistance in the field. Professor Jamie Kirkpatrick and Vishnu Prahalad assisted with vegetation species identification. Dr Kevin Kiernan and Rob Anders contributed technical assistance, Kevin on the site geomorphology and Rob with a real time GPS survey. To those who read drafts and provided suggestions, corrections and the like, Mel Houghton, Christian Mackay, Kate Aalders and Colin Sumner, thank you. The School of Geography and Environmental Studies assisted with vehicle hire, and Dave Green from the School went out of his way to organise field and laboratory supplies, and provide assistance in the environmental laboratory. A special mention goes to Mel Humphries from the School of Maths and Physics. Mel taught me how to use the statistical analysis package R, was always there if I needed guidance with coding and held a genuine interest in my project. Finally, a very special thank you to Dr Peter McQuillan, my supervisor. His untiring enthusiasm for the study, continuous encouragement and support, never wavered over the course of the project. We collected nearly 38 000 invertebrates over 12 months, which Peter identified, many to genus and species level. Peter was constantly surprised with some of the specimens we collected and often expressed “Good grief!” at some of our finds. He was never short on suggestions, maintained an open door and was always happy to discuss the project and read chapters of this thesis. Peter, thank you.

L. Ledeganckstraat 35, 9000 Ghent, Belgium 4 University of Antwerp, Evolutionary Ecology Group, Department of Biology, Groenenborgerlaan 171, 2020 Antwerpen, Belgium Abstract Salt-marsh invasions by the grass Elymus athericus (Poaceae) recently transformed usual areas dom- inated by Atriplex portulacoides (Chenopodiaceae) into homogeneous meadows. Two wolf spider species, Pardosa purbeckensis and Arctosa fulvolineata, show contrasting densities and habitat prefer- ences in salt marshes (respectively dominant and co-dominant ground-living spiders) and oppositely respond to the grass invasion. This allowed us to test whether invasive species that alter habitat struc- ture affect reproduction in addition to previously recorded changes in density. Reproductive traits (female mass, cocoon mass, number and volume of eggs, hatched cocoon as a proxy of reproduc- tion date) were studied in both invaded and natural salt marshes during 2007 and 2008 in the Mont St-Michel Bay (France). In both species, reproductive outputs (cocoon mass) were higher in optimal habitats and volume of eggs was found to be independent from female mass, whereas the latter sig- nificantly influenced the number of eggs.

Brown Figure 6.1: Saltmarsh with samphire, in NY NRM Region. (A) Point Davenport; (B) Winninowie Conservation Park. Photos (c) A. Brown. (B): (c) Google Earth. Asset Saltmarsh and Samphire Description Areas of saline, mineral-rich, organic-rich, and low oxygen coastal soils within and above high tide level, often fronted by mangroves, and backed by saltbush shrubland. Saltmarsh supports various salt-tolerant plants, with samphires being the most common and significant in terms of cover in South Australia. There are distinct assemblages of salt-tolerant invertebrates associated with saltmarsh habitats. Saltmarshes provide habitat for fishes, including juveniles of species which utilise other marine habitats, and are an important feeding area for various bird species, including migratory shore birds. Examples of Birds Main Species Cormorant species (e.g.; Pied, Little Pied, and Black-faced) Caspian Tern and Little Tern Pied Oystercatcher and Sooty Oystercatcher Black-winged Stilt, Banded Stilt, Great Egret, White-faced Heron, Little Egret the threatened species Hooded Plover Little Stint Red-capped Plover Slender-billed Thornbill (Samphire Thornbill) Rock Parrot The raptors Eastern Osprey and White-bellied Sea Eagle Migratory shorebirds listed under international treaties, such as Bar-tailed Godwit, Curlew Sandpiper and Sharp-tailed Sandpiper, Red-necked Stint, Grey Plover , Red Knot, Common Greenshank, Ruddy Turnstones Bony Fishes juvenile Yelloweye Mullet juvenile Greenback Flounder juvenile Southern Blue-spotted Flathead Western Striped Grunter Congolli Glass Goby Small-mouthed Hardyhead Silver Fish Smooth Toadfish Goby species such as Blue-spotted Goby and Southern Longfin Goby Adelaide Weedfish Baker, J.

  • Waterloo Urban and Industrial Expansion Flora and Fauna Survey
    Shire of Dardanup Waterloo Urban and Industrial Expansion Flora and Fauna Survey March 2015 Executive summary This report is subject to, and must be read in conjunction with, the limitations set out in Section 1.4 and the assumptions and qualifications contained throughout the Report. The Greater Bunbury Strategy and Structure Plan identified a potential significant urban expansion area located to the east of the Eaton locality and an industrial expansion area in Waterloo, in the Shire of Dardanup. The Shire of Dardanup (the Shire) and the Department of Planning have commenced preparation of District Structure Plans (DSP) for the urban expansion area and the industrial expansion area. The DSP will be informed by several technical studies including flora and fauna surveys. The Shire has commissioned GHD Pty Ltd (GHD) to undertake a flora and fauna survey and reporting for the Project. The Project Area is situated in the locality of Waterloo in the Shire of Dardanup. The Project Area includes the urban development area to the north of the South- west Highway (SWH) and the industrial development area to the south of the SWH. GHD undertook a desktop assessment of the Project Area and a flora and fauna field assessment with the first phase conducted from 13 to 14 August, 2014 and the second phase conducted from 29 to 31 October 2014. The purpose of this assessment was to identify the parts of the Project Area that have high, moderate and low ecological values so that the Shire can develop the DSP in consideration of these ecological values. This assessment identified the biological features of the Project Area and the key results are as follows.
