The following symposia will be offered at ESA19; You are welcome to submit an abstract for any of the symposia listed below; alternatively, you can send your abstract under the theme of “open forum” for inclusion in the general scientific program.
New Methods and Applications in Urban Ecology
Conveners: Ms Monika Egerer, Dr Emily Flies, Dr Caragh Threlfall, Dr Dave Kendal
Urban environments are now home to over 50% of the human population and a significant proportion of Australia’s threatened plant and animals (Ives and Lentini et al. 2016). Cities are a confluence of sociocultural, physical and biological environments that are a non-traditional but increasingly important home for ecological research. Urban ecologists are developing new techniques, adapting traditional ones to study complex urban social-ecological systems. Given this complexity, interdisciplinary collaboration and communication of new research approaches, methods, and applications are critical. However, there are few platforms to exchange ideas among researchers. This symposium will highlight the latest and evolving research approaches and techniques in urban systems drawing from empirical, theoretical and modelling studies and highlight how these novel techniques are leading to solutions. In this symposium, we will examine questions such as:
-What new approaches and methods in natural and social sciences are being applied to answer urban social-ecological questions?- How can commonly used ecological means be adapted to study urban ecosystems better?
– Which tools and techniques from other fields can answer questions and create solutions in urban ecology?
– What are the strengths and weaknesses of different methodologies when applied to interdisciplinary and practitioner applications?
– Can novel methods characterise and explain the spatial, temporal, and social variation across urban systems in new ways?
The goal of this symposium is to present recent research approaches, techniques and methods that address interdisciplinary questions in urban areas. It will have a strong focus on methodologies, applications and theoretical frameworks used by researchers working on both natural and social science issues in urban ecology. By doing so, it will aim to highlight novel methods and their research application to inspire future investigations and collaborations.
Integrated Landscape Management in the Tasmanian Midlands Agricultural Region and Biodiversity Hotspot.
Conveners: Associate Professor Menna Jones
Aboriginal peoples managed the savannas of the Midlands region of Tasmania for 35,000 years. Two hundred years of European pastoralism and agriculture, with associated tree clearing, fertilisation and the introduction of exotic grasses has led to tree decline, faunal loss and degradation and fragmentation of native vegetation, with <10% woodland and <3% native grassland remaining.
The Midlands is an Australian Biodiversity Hotspot, supporting endemic plants and CWR mammals, with a limited extent of government nature reserves. Remnant vegetation on private land is of high conservation value and is being managed via innovative arrangements with conservation organisations such as Bush heritage Australia and Tasmanian Land Conservancy. Additionally, Greening Australia is leading a restoration project intending to restore and connect remnant woodland to provide habitat and connectivity for wildlife.
With the audacious goal to restore a functional trophic network dominated by native species of mammals and birds, presented will be an animal-centric approach to determining how essential species interact within the landscape in the presence of high densities of feral cats.
Understanding and managing the plant pathogen Phytophthora cinnamomi and other invasive pathogens in natural and managed ecosystems for biodiversity values
Conveners: Professor Giles Hardy
Phytophthora cinnamomi is recognised as a Key Threatening Process to Australia’s biodiversity by the Environment Protection and Biodiversity Conservation Act 1999. It is having a significant impact across southern Australia, including Tasmania and up the eastern seaboard; causing the extinction of species and impacting on Australia’s biodiversity assets. There remain substantial gaps in knowledge and challenges for effective and sustained management to stop its spread and impact.
As part of the Dieback Working Group (an incorporated not-for-profit organisation), an annual Dieback Information Group (DIG) meeting in Western Australia has been run since 2000. The emphasis of DIG is to disseminate research and management findings, listen to stakeholder concerns and to develop ways to manage the pathogen across landscapes collaboratively. It is about ‘Science for Practical Solutions’. DIG is attended by up to 300 stakeholders (researchers, government and non- government agencies, NRM groups, ‘friends of’ groups and industry). Contributors/speakers are from all of the stakeholder groups to ensure all issues and concerns are covered. At least one speaker from overseas or the Eastern States contributes.
Furthermore, such training is relevant to anyone working in the natural environment, including many ESA attendees. There is a need for restoration ecologists, botanists, plant physiologists, climate change scientists, fire ecologists and zoologists/native fauna ecologists, social scientists, on-ground practitioners and others to get involved.
Using ecological traits of invertebrates to understand ecosystems
Conveners: Associate Professor Heloise Gibb, Professor Nigel Andrew
This symposium will explore the evidence that we are heading in the right direction, examine the variety of traits used, their links with ecological function and their effectiveness in predicting responses to environmental change. We will also consider statistical and modelling approaches to trait analysis, the availability of trait data and the critical steps to advancing our understanding of ecosystems through invertebrate trait ecology.
Functional traits are considered essential to the development of a general theory of ecology. Invertebrates are an ideal group for which to ask questions about relationships between assemblage structure and the environment because of their diversity, but invertebrate ecologists struggle with the quirks of species responses. They are therefore extremely well suited to a trait-based approach to understanding ecological communities. Trait-based ecology has been overwhelmingly focussed on plants, but different lifeforms likely have very different insights to offer in this field.
A range of disciplines will be closely aligned to ecologies such as statistics, behaviour, physiology, and mathematical modelling. Speakers will be asked to present their latest findings within the framework of the symposium.
1. Linking traits with function: morphological, behavioural, physiological, life history;
2. Trait responses to the environment;
3. Statistical and modelling approaches to trait analysis,
4. Advances in trait data availability and databases.
Speakers will be invited that will address one or more of the four key symposium themes. This symposium would appeal to members studying invertebrates and any researchers working on traits in other taxonomic groups, particularly plants.
Science-in-practice: challenges, successes and lessons learnt
Conveners: Dr Chloe Sato, Dr Karen Ikin
This symposium is intended as a critical reflection of the design, communication, and implementation of applied ecology. The symposium will involve case-study presentations from academics and government and non-government practitioners on the challenges and successes they have experienced in researching or implementing evidence-based land management.
Following these presentations will be a facilitated discussion of the common themes to identify key ways to address the challenges of getting science into practice for improved biodiversity conservation outcomes. The anticipated results of the symposium will be a summary document provided to the ESA Practitioners Working Group to develop into an ESA document for broader dissemination.
This symposium is motivated by our personal experiences of working as both academic researchers and government environmental land managers; seeing first-hand the logistical gulf between “science” and “practice”. Much ecological research is termed “applied” because it addresses a practical management question. However, it is difficult to: (1) design studies that are transferable to the scale and constraints of real-world land management; or (2) to publish, in high-ranking international journals, the detail necessary to implement research findings.
This symposium is intended to raise this awareness and kick-start the discussion. The symposium will be structured, so 90 minutes is allocated to presentations, followed by 30 minutes to discuss the common themes raised and identify critical points for lessons moving forward. All speakers will be asked to critically reflect on their experiences, through case studies of their research or land management programs. We will open and provide a synthesis of the presentations, and contribute one presentation.
From the nominations received a career-stage and diverse gender representation of researchers and practitioners working in applied ecology will be picked.
Field-based manipulative experiments for understanding environmental change
Conveners: Dr Susanna Venn, Professor Sally Power
Documenting change, and demonstrating biological responses to the environment, is essential work that will continue to build our understanding of ecosystems and reveal gaps in our ecological knowledge.
But what’s going on?
Manipulative experiments, especially those conducted in-suit in the field, perhaps along environmental gradients, can be a powerful tool for isolating the various environmental parameters and identifying the underlying mechanisms that are driving biological responses.
Insights gained from such experiments can then be used to build more accurate models of environmental change, which may ultimately lead to policy change and practical solutions for conservation efforts.
Demonstrated will be the commonalities among experimental approaches, data analyses, experimental artefacts and outcomes, regardless of the target species, expected responses or ecosystem, whether it be terrestrial, freshwater or marine.
Practitioner Insights into Ecology
Conveners: Dr Sacha Jellinek
Ecological practitioners are employed in a large number of public and private sector jobs, and this symposium will highlight the importance of these positions in applying and informing ecological science. It will highlight the different work that ecological practitioners undertake as consultants, teachers, staff for non- government organisations and those working for Government agencies and research bodies. Some of the presentations on the roles that practitioners undertake will include using best practice ecological monitoring and assessment techniques in the field in collaboration with University staff and students; using legislation to protect ecological systems, modelling species movements and prioritising conservation works, and engaging our next generation of scientists and conservationists.
The PEWG aims to facilitate practitioner engagement in high quality and relevant research in ecology; encourage practitioners to engage with and become members of ESA and develop mechanisms to engage ESA with non-member practitioners effectively.
Using new research results to manage Tasmanian devil facial tumour disease better
Conveners: Professor Hamish McCallum, Dr Rodrigo Hamede
This symposium will present new research from several groups across Australia and internationally working on Tasmanian facial tumour disease (DFTD) using a range of disciplines and aims to generate a lively and meaningful discussion on how to use this new knowledge to improve practical conservation strategies for the Tasmanian devil.
It is now more than 20 years since the emergence of Tasmanian devil facial tumour disease, a bizarre infectious cancer that threatened to cause the extinction of this iconic species. Recent developments have made it critical to re-evaluate management strategies for the Tasmanian devil and DFTD. The disease now covers almost the entire range of the devil, having recently reached the west coast of Tasmania.
The challenge now is how best to manage the long-term coexistence of devils and the disease, including managing impacts on the rest of the Tasmanian ecosystem.
This symposium will be structured around six 15 minute talks, followed by three 5 minute speed presentations from PhD students, finishing with a 15-minute panel discussion combining managers and researchers to evaluate future management actions Symposium justification.
Communicating ecology through art
Conveners: Dr Kirsten Parris, Dr Ayesha Tulloch
This symposium will highlight innovative ways to express ecology through performance and participatory art, including music, dance, soundscapes, crafting and the visual arts. The creative use of these media often allows audiences and participants to connect with biodiversity, place-based nature and ecological principles in ways that more traditional approaches to communicating ecology do not.
The symposium will include a combination of,
1) presentations about recent events or activities at which ecology was successfully communicated through art and,
2) on-the-spot communication of ecological ideas and information through performance or participatory art. Students and early- career researchers will be particularly encouraged to participate. Prizes for best paper by a student and best paper by an ECR will be offered (currently employed at Level A or B or < 5 years FTE post-PhD). The symposium will be a vital activity of the ESA’s Research Chapter for Science Communication, which was launched in 2017.
This symposium relates directly to the conference theme of “Science for Practical Solutions”. Implementation of practical solutions to environmental problems will require effective communication of ecological principles and research findings to diverse audiences, both in Australia and internationally.
The symposium will focus on approaches to science communication for ecologists that are both innovative and interdisciplinary, with an active, creative component. Conference sessions on science communication resonate strongly with ecologists; previous symposia at EcoTAS 2017 and ESA2018 were very well attended and very well received.
Ecologists Weaving Knowledge on Country
Conveners: Dr Rosemary Hill
Ecology in the 21st Century recognises that multiple sources of evidence from diverse knowledge systems contribute to humanity’s understanding of the interactions among all forms of life and the environments they inhabit, and in turn, change and shape. The ecological knowledge embedded in the Indigenous Knowledge Systems (IKS) of Australia’s Aboriginal and Torres Strait Islanders is of growing importance in natural resource management, and protected areas.
Ecological understanding from both science and IKS is fundamental to Australia ecology and environmental policy.
Management of overabundant macropods
Conveners: Dr John Read
Overabundant kangaroos and in some cases smaller macropods pose a significant threat to the conservation or restoration of native vegetation remnants and their flora and fauna.
Unsustainably high macropod densities can also be detrimental to animal welfare outcomes (evidenced by many starving kangaroos) and agricultural productivity.
This symposium aims to highlight several case studies where these threats have been measured and to showcase examples of how such risks can be managed.
Solutions from above and below: Plant-soil research addressing climate change and biodiversity loss
Conveners: Dr Adam Frew, Dr Anna Hopkins
Interactions between soil and plants are fundamental to ecosystem function and resilience. As we face the challenges of climate change and biodiversity loss, the ability to apply our understanding of plant-soil interactions towards the development of solutions is becoming increasingly important.
As part of the Plant-Soil Ecology Research Chapter, this Symposium will showcase recent advancements in our understanding of plant-soil interactions under climate change, and how current knowledge can contribute towards solutions addressing the consequences of anthropogenic-driven disturbance and biodiversity loss.
The symposium builds on the successful symposium in the plant-soil space held at ESA in 2018 (as part of the Plant-Soil Ecology Research Chapter) as well as the successful microbial ecology symposia held at ESA in 2016 and 2017. This symposium brings together an exciting collection of ecologists working in the plant-soil space from a diverse range of perspectives. It aims to continue the theme of previous symposia bringing the ideas of soil and microbial ecology to mainstream ecology by showcasing cutting-edge research being carried out in plant-soil interactions.
Although broad in scope, this symposium will synthesise new knowledge from plant and soil research (ranging from reductional experimental approaches to long-term field studies) and apply it to manage our increasingly anthropogenically-modified environment better.
Adaptive management: walking the talk
Conveners: Dr Vanessa Westcott
Adaptive control is a phrase often used in ecological research and conservation programs but seldom implemented using high quality, transparent data analysis as a foundation for altered practices.
Private landholders want and need to be able to measure, evaluate and share the benefits they see from their conservation efforts to leverage ongoing support. Improvements in the adaptive management space include the use of standard language and symbology, a broader strategic vision that goes beyond a project by project approach, structured monitoring plan development, regular stakeholder engagement and robust question-based data analysis.
In this symposium, there will be speakers providing an overview of the theory as well as multiple best-practice examples of adaptive management tools and projects currently underway.
Vegetation science for decision-making
Conveners: Ms Sarah Luxton, Dr John Hunter
This symposium aims to bring together a multi-disciplinary group of ecologists, analysts and policy-makers to discuss:
• The gaps between Australia’s current vegetation system and international standards,
• Innovative solutions to data-deficiencies,
• State, territory and federal developments; and
• Examples of modern techniques in vegetation classification in the Australian context.
Without adequate data and the development of international-level methodologies which allow cross-jurisdictional analyses and robust hierarchical classification, professional assessments cannot be made relatively or scientifically. The goal of our symposia is to bring together ecologists who are interested in the intersect between vegetation data, classification, map-products and decision-making.
