Klomp Green, D.G., Klomp, N.I., Rimmington, G. & Sadedin, S. (2006). Complexity in Landscape Ecology. Springer, Dordrecht. This 208-page book presents a new perspective on traditional ecology. We employed recent advances in modelling, artificial life and complexity theory to provide new insights into patterns and processes in landscapes and ecosystems. The text uses new and existing data to integrate disparate disciplines to better understand and manage complex landscapes. Voltier, S.C., Furness, R.W., Bearhop, S., Crane, J.E., Caldow, R.W.G., Catry, P., Ensor, K., Hamer, K.C., Hudson, A.V., Kalmbach, E., Klomp, N.I., Pfeiffer, S., Phillips, R.A., Prieto, I., Thompson, D.R. (2004). Changes in fisheries discard rates and seabird communities. Nature 427: 72-730. ISI 32.182, 25 citations. Published in one of the world’s most influential journals, our paper presented the results of a long-term, multinational study to dramatically illustrate how current fisheries and management policies adversely affect bird communities. The study has been cited as a classic example of the complex interactions within ecosystems, and illustrates how ill-informed policies or practices can have significant effects on the natural environment.

ISI 1.206, 11 citations. Published in one of the world’s leading ornithology journals, this paper is another example of the extent of my international collaborations, here with British and Spanish researchers. This paper provided data and new explanations of the factors that influence survival of long-lived animals. 1 Weerheim, M.S, Klomp, N.I., Brunsting, A.M.H. & Komdeur, J. (2003). Population size, breeding habitat and nest-site distribution of little penguins (Eudyptula minor) on Montague Island, New South Wales. Wildlife Research 30: 151-157. ISI 0.993, 0 citations. This study documents the habitat factors affecting the population of penguins on Montague Island—one of the world’s largest Little Penguin colonies, but previously poorly documented. This international collaboration between the CSU and staff and students from Wageningen University (Netherlands) examined the effects of current management practices on seabirds breeding on the island, drawing on historical and current data to establish the baseline and methodology against which all future studies can be compared.

In this paper my colleague and I analysed data from published papers to identify circumstances under which genetic differences among populations can develop in aquatic ecosystems. It was the 7th most downloaded paper on the MFR webpage in 2006. This paper follows on from several highly cited papers in internationally refereed journals where we examine factors affecting biodiversity, dispersal and gene flow in aquatic environments. (eg. Watts et al. 1990, Marine Biology 105, 145-152, 73 citations). This body of research has been cited by eminent authors in several review papers and has implications for managing fish stocks, designing aquatic reserves and conservation.

ISI 1.44, 2 citations. This paper presents results from an ARC project that developed ecological indicators for assessing environmental flows. It highlights the effects of flow regime, specifically water velocity, on river ecosystems. This research has underpinned recent changes to dam management practices, including several studies of cyclic flow releases from Dartmouth Dam by the Murray-Darling Basin Commission (Watts et al. 2005; http://www.csu.edu.au/ research/jcentre/reports/jcec_report97.pdf, Watts et al. 2006 http://www.csu.edu.au/research/ ilws/archive05/ILWSreports06.htm,). This research has been presented at three international conferences (Riverine Landscapes Sweden, TISORS Scotland, Riversymposium Brisbane) and has influenced dam management practices by demonstrating that improved river health can be achieved without increasing environmental water allocations. Watts, R. J. & Ryder, D.S. 2001. Developing biological indicators for the assessment of environmental flows. Australian Journal of Water Resources, 5(1): 119-122. SIS N/A, 2 citations This paper addresses the issue that there is poor river health downstream of dams and that appropriate indicators are required to assess the impacts of environmental flows. Published in a special issue focussing on environmental flows, this paper summarises findings from several multidisciplinary research projects. The indicators developed by these projects have been used to assess flow releases from Dartmouth Dam by the Murray-Darling Basin Commission (eg. Watts et al. 2006’ http://www.csu.edu.au/research/ilws/archive05/ILWSreports06.htm). This research has been presented at three international conferences (International Society for Limnology Melbourne, Riverine Landscapes Sweden, TISORS Scotland) and was featured during National Science Week in 2004 (http://news.csu.edu.au/director/features/science). 2 Watts R.J. & Wilson, A.L. 2004. Triage: Appropriate for prioritising community funded river restoration projects, but not for advancing the science of river restoration. Ecological Management and Restoration, 5: 73-75. (This journal is in an emerging field and is not yet listed on the ISI database). This paper discusses the issue of how to best prioritise river restoration projects and is an output of a project undertaken in collaboration with CSIRO and funded by a nationally competitive grant from Land and Water Australia. We collaborated with catchment management agencies in SA, Victoria, and NSW to trial the assessment techniques (Wilkinson et al. 2004, 2005a, 2005b http://www.clw.csiro.au/publications/technical2004/ tr37-04.pdf, http://www.clw.csiro.au/publications/consultancy/2005/ Goulburn Broken riparian.pdf; http://www.clw.csiro.au/publications/consultancy/2005/Mount Lofty Ranges riparian.pdf) and the results were used by one of the CMAs to implement river restoration programs costing in excess of $1M for fencing and replanting of riparian zones. This research was presented at the international Riverine Landscapes conference in Sweden. Dr. Iain R. Taylor Richardson, A.J., Taylor, I.R. & Growns, J.E. 2001. The foraging ecology of egrets in rice fields in southern New South Wales, Australia. Waterbirds. 24: 255-264. ISI: 0.5; 9 citations. Funded by a Natural Heritage Fund grant to Taylor, this was the first quantitative investigation in an on-going debate on the ecological adequacy of rice fields as a substitute for natural wetlands in Australia. The paper led directly to two research contracts to Taylor from Murrumbidgee Irrigation, which demonstrated conclusively that rice fields are not an adequate substitute and that environmental flows are needed to maintain natural wetland biodiversity. Five journal publications will be produced from this work and Taylor has been invited to contribute a chapter to a book on the international role of rice fields in biodiversity conservation. Taylor, I.R. & Grant, M. C. 2004. Long-term trends in the abundance of breeding Lapwing Vanellus vanellus in relation to land-use change on upland farmland in southern Scotland. Bird Study 51: 133-142. ISI: 0.99; 2 citations. The study concerned a waterbird whose populations have declined seriously. Its importance lies in its long-term nature, covering 25 years, enabling a direct quantitative linking of population change to specific aspects of land-use change. The study exemplifies some of the international links that have been established between the aquatic group and overseas researchers. Taylor conducted the research up to 1993 when he moved to Australia but it was deemed important enough for its continuation by Dr. Grant, senior researcher in the Royal Society of the Protection of Birds, UK to 2004. The research link continues with studies of other species. Taylor, I.R. & Roe, E. L. 2004. Feeding ecology of Little Terns Sterna albifrons sinensis in south-eastern Australia and the effects of pilchard mass mortality on breeding success and population size. Marine and Freshwater Research 55: 1-10. ISI: 1.48; 2 citations. This paper involves a species that at the time of the study was listed as endangered in Australia and investigated the effects of a human introduced disease of pilchard on the survival of the species. It is the only study of the species in Australia and provided essential information for its conservation, being used by the Department of Sustainability and Environment, Victoria. The findings have also been incorporated into a set of international rules and recommendations by Birdlife International, the recognised international authority, to define limits around seabird nesting areas that should be protected. 3 Hamilton, A.J., Robinson, W., Taylor, I.R. & Wilson, B. 2005. The ecology of sewage treatment gradients in relation to their use by waterbirds. Hydrobiologia 534: 91-108. ISI: 0.56; 1 citation. The effect of nutrient enrichment from human sources on biodiversity is a constant problem in aquatic ecosystems. Previously, there was no quantification of the direct links between chemical concentrations and the densities of higher vertebrates. This study made use of a gradient in nutrient concentrations in a series of ponds at a sewage treatment facility to quantify all steps in the process, including the numerical effects on selected waterbird species. It is the first study in Australia to do so and the first to demonstrate a direct link between the chemicals and numbers of higher organisms.

River Research and Applications, 22: 525-542. ISI: 1.645; 0 citations. This paper represents an important step forward in our understanding of riverine habitat and its management and is published in a leading international aquatic journal. It is one of the few riverine experiments investigating the manipulation of habitat in situ. Our results have major significance for the sustainability of fish populations in lowland rivers and are already contributing to the management of lowland rivers through state conservation agencies (e.g. DSE, Victoria) and catchment management authorities (e.g. Goulburn-Broken CMA) implementing works to provide flow refuge for young fish.

This paper was one of the first dealing with the early life history of the iconic Murray cod. Despite much work over an extended period of time, knowledge of this species’ early life history is still in its infancy. Although the paper has only been out for a short time, it is generating much interest from Australian researchers, since the results about spawning time and drifting behaviour have profound implications for river management and conservation of Murray cod. King, A.J., Humphries, P. and Lake, P.S. (2003). Use of floodplain environments during high and low flow conditions by larval and juvenile fish. Canadian Journal of Fisheries and Aquatic Sciences 69: 773-786. ISI: 1.882; 19 citations. This paper represents the first study to sample inundated floodplains for fish in the MurrayDarling Basin in a rigorous way, and is published in one of the top international aquatic journals. Despite conjecture, no studies had directly investigated whether fish used the floodplain and for what purpose. Our conceptual model on breeding and floodplain usage by fish showed that for many species, use of the floodplain for breeding does not make sense. This work has been taken up by managers and other Australian scientists (12 citations). The conceptual model is also being taken up by overseas workers (7 citations), as being relevant to temperate floodplain river systems generally. Humphries, P., Serafini, L.G. and King, A.J. (2002). River regulation and fish larvae: changes in space and time. Freshwater Biology 47: 1307-1331. ISI: 2.502; 22 citations. This paper, published in a leading international journal (6th of 79 in marine and freshwater biology), was important in showing that fish spawned every year, despite large inter-annual 4 variation in flow. This contradicted much of the current thinking and has huge implications for river management. The paper points to recruitment as being the major reason for declining fish populations, not spawning. Its impact is seen by the number of citations, 6 of which are from international researchers. Dr. Andrea Wilson.

Ecological Management & Restoration, 7(2): 123-129. (This journal is in an emerging field and is not yet listed on the ISI database). This publication detailed research work that was instrumental in the development of RARC, a rapid assessment technique for measuring riparian condition in south-eastern Australia (www.rivers.gov.au/acrobat/techupdate4.pdf). The RARC tool has been widely adopted by industry, natural resource managers, landholders and scientists (e.g. Land, Water & Wool program, www.rivers.gov.au/lww/rarc.htm). Workshops to provide practical demonstrations and training in its application have been held by Land & Water Australia throughout southern Australia. RARC has formed the basis of new assessment tools tailored for use in riparian condition assessments for Tasmania, South Australia and northern Australia (e.g. TRARC).

Aquatic Ecology, 39: 189-200. ISI 0.898, 0 citations. The research underpinning this publication has been disseminated to both agricultural and ecological audiences at local, national and international workshops and conferences (e.g. British Ecological Society, International Congress of Entomology, Societas Internationalis Limnologiae). This work formed an important component of rice field biodiversity studies in the research programs of the Cooperative Research Centre for Sustainable Rice Production. The Context Statement History and research objectives Australia’s rivers, floodplain wetlands, estuaries and marine near-shore ecosystems are ecologically interconnected and all have been adversely affected by the processes of agricultural development, river regulation and recurring drought. Problems of conflicting demand for water and consequent ecosystem dysfunction are likely to be exacerbated in the future by long term climate change. The objectives of the research group are to improve our understanding of the basic ecological functioning of these aquatic systems and to work with various end-users to improve the management of our aquatic resources for the benefit of all who value and rely on these resources. The work of our group is particularly targeted at understanding the ecological impacts of river flows, the effects of river regulation, and ways of ameliorating adverse effects. The aquatic group was started in 1994 and has grown steadily in size and influence since, within the former Johnstone Research Centre and current Institute of Land, Water and Society (ILWS) of CSU. The commitment of the University to the future of aquatic research and our group is reflected in the recent appointment of Professor Max Finlayson, an eminent international aquatic ecologist as a Strategic Professor and Director of ILWS. The strength of the group will be increased to seven in the coming months by the addition of Prof. Finlayson and Dr. Skye Wassens. Group members have expertise in water regimes and flows, plant productivity, invertebrate, fish, amphibian and waterbird populations. 5 Main achievements In 2001-2006 the group produced 51 peer reviewed publications (33.6 DEST points), and attracted $1,646,272 of research funding, including $387,252 in nationally competitive grants. Among the publications was a paper in Nature (N. Klomp). Group members initiated 26 separate funded research projects and produced 22 research reports for various clients. Group members have served on 15 advisory committees and panels concerned with wetland management. All group members act as referees for international journals. Group members were principal supervisors for 9 postgraduate degree completions. Three of these graduates are now university lecturers, two are postdoctoral fellows and four are employed in research organisations or river management agencies. Our research activities were linked to postgraduate training through the establishment by the group of a Postgraduate Certificate in River Restoration and Management in 2004 at CSU, supported by a nationally competitive grant from Land and Water Australia. This provides high level training in aspects of water management required by a variety of end-users. The international standing of the researchers in the group and the quality of the research undertaken by the group has been recognised in several ways. Robyn Watts and Andrea Wilson were members of a team that won the 2001 CSU Vice Chancellors Award for Team Research into river and floodplain ecology. Several members of the group have given invited presentations at international conferences, e.g. Iain Taylor received 5 invitations to present at overseas international wetland conferences. Robyn Watts and Iain Taylor contributed to a national conference on wetland management and the proceedings were edited by Iain Taylor. Collaboration There is extensive collaboration and cross linkages both within the group and between the group and other researchers and a wide range of end-users. This takes the form of funded and unfunded research projects, consultancies and other advisory positions, the supervision of postgraduate research projects, and the organisation of research meetings and conferences. Group members and their postgraduate students meet regularly both informally and formally to discuss our research activities and obtain group feedback on our work. Many of the group’s funded research projects have involved at least two members of the group. For example, Robyn Watts and Andrea Wilson have collaborated on four recent research projects. All members of the group contribute as supervisors and co-supervisors of the pool of postgraduate students. It is especially valuable that members of the group are able to collaborate with other academic staff within the Institute of Land, Water and Society of CSU. This gives added strength and dimension to the group, enabling a holistic approach to the management of aquatic resources and better guarantees for the future sustainability of the group. Thus, within CSU, aquatic ecology group members have collaborated with social scientists, hydrologists, geomorphologists and spatial scientists who have specialist interests in natural resource management. Examples of collaboration of this nature have been between Robyn Watts and Alan Curtis and between Nick Klomp and David Roshier. All members of the group have collaborated with researchers external to the university. We have undertaken projects with researchers at La Trobe Univeristy, Monash University, Murray-Darling Research Centre, University of New England, CSIRO Land and Water, the University of Tasmania and the University of Western Australia. Funded collaborative projects with agencies and end-users outside CSU have involved the Murray-Darling Basin Commission, Murray-Darling Freshwater Research Centre, Department of Sustainability and Environment, Murrumbidgee CMA, Sunraysia CMA, 6 Murrumbidgee Irrigation, NSW Dept of Environment and Climate Change (formerly Parks and Wildlife), NSW Fisheries Scientific Committee, Land and Water Australia and Fivebough and Tuckerbil Wetlands Trust. It is important to stress the nature of these collaborations: group members discuss and identify specific management requirements and design research projects with these end-users, and most importantly, are active with them in the implementation stage either as incorporation into policy or into on-ground works. This is exemplified by the very large number of research reports (22) written for these end-users. There is an international aspect to some of our collaborative research as the group has links with several international organisations. Paul Humphries has established international research links with colleagues at the University of Vienna and the Texas A & M University. Iain Taylor has co-authored a journal publication and initiated new research collaboration with members of the research branch of the Royal Society for the Protection of Birds in the UK. Several of his projects have involved Wetlands International and the Royal Society for the Protection of Birds, UK. Robyn Watts has links with civil engineers and ecologists from the Japan Water Resources Environment Technology Centre and hosted a visit by a delegation from this organisation in 2006. Iain Taylor is also involved in exploratory discussions with the president of Wetlands International on the provision of wetland training programs in Asia.

Our group’s research has had an impact in the management of all of these components. However, the impact of our research activities defined in terms of our engagement with end-users, the take up of research results and the benefits to society as a whole can be best illustrated by our collaborative work with various agencies and other endusers within the Murrumbidgee, Murray and other river catchments in New South Wales and northern Victoria. These catchments are places where people work, earn a living and meet their recreational needs as well as being areas within which Australia has to meet its national and international responsibilities in environmental management and conservation. Water is an essential resource in all of these aspects of human endeavour. The work of our group has been particularly targeted at understanding the ecological aspects of river flows, the effects of river regulation and ways to ameliorate adverse effects. Our group has very close working relations with agencies and organisations that are responsible for managing all aspects of aquatic resources within their catchments. This includes the Murrumbidgee, Murray, Sunraysia and Goulburn-Broken Catchment Management Authorities, Murrumbidgee Irrigation, Land and Water Australia, NSW Department of Primary Industries, Statewater Corporation, Murray-Darling Basin Commission, Natural Heritage Trust, NSW Fisheries Scientific Committee, Department of Environment and Climate Change, NSW, and Fivebough and Tuckerbil Wetlands Trust. Although we have had funded research projects with all of these organisations, the engagement has not simply been in the undertaking of funded research. Our group members discuss and identify specific management and knowledge requirements with these end-users, design research projects together, and most importantly, have been active with them in the implementation stage. We have researched and developed evidence-based management strategies on river flows, indicators of river health, the conservation of native fish, amphibian and waterbird populations and river restoration practices. We have produced 22 research reports on these aspects, specifically for these end-users. In the area of wetland management for biodiversity conservation our engagement with Fivebough and Tuckerbil Wetlands Trust, which operates within the Murrumbidgee Catchment, has been especially productive. One of the group (Taylor) is a Board Member of the Trust and has provided ecological advice and undertaken targeted joint research with Mr. M. Schultz, President of the Trust, over a period of 10 years. Improved management of Fivebough and Tuckerbil Swamps based directly on our research findings resulted in their successful nomination in 2001as a Ramsar site, that is, a wetland complex of international conservation importance. The requirement to produce an effective management plan for the 8 wetlands as part of the Ramsar nomination process was possible only as a result of our research. There are several novel aspects to the management of the site: it is normal for there to be community consultation in the management of conservation areas but in this case members of the local community through the Board of the Trust are actually responsible for all aspects of management. Controlled livestock grazing is used successfully as a management tool, apparently the first instance of this in Australia. The site won the New South Wales inland tourist destination award for 2007 based on its wildlife values. Fivebough Swamp is now used as a model of wetland management in New South Wales and has been presented as an Australian case study of river flows and river basin management to the international Ramsar Convention in Switzerland. Capacity building for catchment management The aquatic ecology group has a strong emphasis on using our knowledge and expertise to build capacity for better management of river catchments, estuaries and near shore ecosystems. One of the main limitations in the implementation of evidence-based management of aquatic resources within Australia and elsewhere is the shortage of suitably trained managers. Our group has been especially active in the use of our research results and experience gained through the research in the area of capacity building for improved river and wetland management both within Australia and overseas. A substantial number of postgraduate research students have been supervised and a Postgraduate Certificate in River Restoration and Management, which provides much needed training within Australia, was introduced at CSU by Robyn Watts and Andrea Wilson. This was supported by a nationally competitive grant from Land and Water Australia. A specialist subject in wetland and waterbird management was also introduced into a Postgraduate Diploma course in Ornithology at CSU by Iain Taylor in 2005. The emphasis in these courses is on a quantitative, evidence-based approach and our research feeds directly into the courses by the use of our specific case studies. Our group has been active in capacity building with management agencies throughout eastern Australia, acting as a catalyst to encourage the exchange of knowledge and ideas on wetland management among professional managers. For example, in 2006 Iain Taylor in collaboration with Fivebough and Tuckerbil Wetlands Trust and Murrumbidgee Catchment Management Authority, organised and edited the proceedings of a national conference on wetland management in production landscapes, which was attended by 150 delegates from agencies across south east Australia. Other examples are several field days and workshops organised by Robyn Watts and Andrea Wilson to engage the community in river management, and a sampling protocol for the assessment of algal responses to environmental flows developed for NSW DECC as part of an ARC funded project by Robyn Watts. There is also an international aspect to our capacity building: in 2003 Iain Taylor was invited to attend a workshop in India organised by Wetlands International on capacity building for wetland management in Asia. This will be developed further with Max Finlayson, President of Wetlands International, when he joins the aquatic group later in 2007. One of our group’s aims is to become a centre for aquatic ecosystem management capacity building for the Australia-Asia-Pacific region. 9 Contacts for reference Dr. Brendan Edgar, Program Coordinator, National Rivers Consortium, Land and Water Australia, GPO Box 2182, Canberra, ACT 2601.
