ABSTRACT.

This talk will present an overview of Si biogeochemistry in aquatic ecosystems. The availability of silica can help structure aquatic phytoplankton communities with Si-requiring diatoms being an abundant and important group supporting food webs in marine and freshwater communities. Lake Michigan is a large freshwater lake within the Great Lakes which is showing long term increases in Si over the last decade. This cannot be explained in terms of changes to inputs, or changing Si demand by diatoms.

This talk with present some of our research to better understand Si cycling in the Lake, and to define the ‘players’ in freshwater Si cycles. Comparisons will be made with recent work on Si incorporation and labelling in marine macroalgae and phytoplankton species in Tasmania.

BIO.

Erica completed a BS with first class honors in Botany at University of Western Australia before heading to Sweden to work with symbiotic cyanobacteria. She returned to Monash University for a PhD in microalgal physiology of photosynthesis and nitrogen metabolism. After a post-doc in Ireland working on large kelps, she moved to University of Wisconsin on the shores of Lake Michigan.

Her current research spans microbial biodiversity and community analysis, nutrient transformations by key enzyme activities in algal and microbial communities, to biogeochemical cycling of macronutrients in lakes, ponds and coastal oceans. Recent work on silica cycling has brought her to Hobart for a sabbatical at Institute for Marine and Antarctic Studies at University of Tasmania.

ABSTRACT.

One of the main mechanisms in Australia’s Commonwealth climate change policy is the Emissions Reduction Fund (ERF). It is an auction where prescribed actions that reduce or offset CO2 emissions can be offered in tender rounds and least cost per tonne CO2 offset offers are funded. Whilst activities across the economy such as building energy efficiency, land fill methane emissions reduction are possible, most credits issued through the ERF to date involved avoided deforestation (17 percent of registered credits) and assisted natural regeneration of native vegetation (64 percent of registered credits (Evans, 2018). Further credits were very concentrated in one part of northern New South Wales and southern Queensland where the removal of stock from low economic return, open forest/grazing land to acquire carbon credits was possible (Evans, 2018). Less than a fraction of one percent of credits came from South Australia intensive agriculture (i.e. areas cleared for broad acre cropping/grazing) representing approximately 10 million hectares (11 percent of South Australia’s area).

Professor Connor will present an overview of a project undertaken in collaboration with the South Australian Government to assess carbon offset supply and co-benefit potential for more future South Australian participation in the ERF. The presentation is in three parts covering the three themes researched for the project. One part provided an informed scientific and economic basis to understand the spatially varying economics of supplying carbon abatement opportunities though land use change across South Australia’s intensive agricultural zone. Another component assessed the often discussed potential that value of co-benefits from carbon plantings in addition to supplying carbon offset markets can provide additional incentives to encourage wider adoption of environmentally and economically beneficial behavior. A final component assessed policy context and stakeholder perceptions to understand how details of implementation of the ERF that may be limiting potential for South Australian landholder participation.

BIO.

Professor Connor specialises in quantitative economic, environmental and social integrated systems modelling often working closely with governments at local, state, national and international levels to provide economic policy advice based on rigorous economics. Jeff worked as an economist and group leader at CSIRO from 2001-2016 where he provided research and advise to the Murray Darling Basin Authority, natural resource management boards and state departments for water, agriculture and natural resource management in South Australia, Victoria, and Western Australia and in Bangladesh, Indonesia, China and Laos. He has secured and/or managed over $6 million worth of externally funded research and published over 60 peer reviewed articles and book chapters in water resource and environmental economics.

ABSTRACT.

The Australian Wet Tropics World Heritage Area is the highest biodiversity region in Australia (45% of all vertebrate species) and was recently described as the second most important World Heritage Area in the world because of the unique concentration of endemic, rare and ancient species. The vertebrate fauna of the Wet Tropics has outstanding and exceptionally high levels of endemism and diversity with the highest concentration in the mountain rainforests.

Unfortunately, the amazing biodiversity of the Wet Tropics World Heritage Area is in trouble. Long-term monitoring demonstrates that many species have already declined in both distribution area and population size and these trends are continuing. Declines are particularly obvious in the endemic, rare, ancient and rainforest specialized species that are the key components of the regions outstanding value. Climate change is already causing significant impacts with many species disappearing at the lower elevation, warmer part of their range – Ringtail Possums and approximately 50% of the rainforest birds already show changes in abundance and distribution in accord with expectations associated with climate change. In fact, impacts are happening earlier and faster than predicted. There is a very real potential for significant biodiversity loss, especially of the high conservation value species that the region was originally protected to preserve.

BIO.

I founded the Centre for Tropical Biodiversity & Climate Change research (CTBCC) at James Cook University in 2006 and was the inaugural Director for six years (2006-2012) and subsequently the program leader for the Global Change Program. I was the convenor/director of the NCCARF National Adaptation Research Network – Terrestrial Biodiversity (2009-2013) and then directed the Natural Ecosystems Network under NCCARF II (2014-2017). I was the founding Chair of the IUCN Climate Change & Biodiversity Specialist Group and Chaired the Wet Tropics Management Authority Science Advisory Committee for five years.

My research is focused on understanding biodiversity, assessing the vulnerability of ecosystems to global change and using this knowledge to maximise the positive benefits of natural resource management and policy.

ABSTRACT.

Climate warming is one of the most prominent driver of community change in regions relatively unaffected by direct human impact. The largely pristine high altitude and high latitude regions of the N hemisphere are warming at much higher rates than the global average.

To investigate how and at which rates global changes affected European high-altitude plant communities over the past century, we assembled a long-term (>100 years) dataset of plant community re-surveys on over 300 European mountain summits. I will present how high-alpine plant communities changed in richness and functional composition, which types of species are prone to local extinctions, and how changes relate to different climate change drivers.

RESEARCH INTERESTS.

Due to the narrow climatic constraints, the strong environmental gradients and the relative naturalness, alpine and arctic ecosystems have been a major playground for generations of researchers. My research deals with the impacts of climate change, agriculture and tourism on alpine and arctic plants and soils, and the interaction between the two.

ABSTRACT. The red fox (Vulpes vulpes) is a mammalian mesopredator with global relevance for conservation and often subject to control efforts. One such example comes from grouse conservation in the forest-farmland mosaic landscapes of Europe. Although not threatened at a global scale, many Central European grouse populations are red-listed and suffer from low reproductive success. Predators of eggs and chicks, especially generalist predators that benefit from landscape fragmentation, have been implicated in this development. While intensive control of predator abundance can benefit prey populations, in practice the effectiveness of predator control is rarely quantified, contesting the appropriateness of predator control as a conservation measure. Our current research focusses on this topic, zooming in on a declining remnant population of capercaillie (Tetrao urogallus) in the Black Forest, Germany. We first assessed how range contractions of capercaillie in the area may be linked to landscape configuration and predator abundance before looking at potential pathways, the suitability of predator control as a conservation tool and the effectiveness of the currently applied restricted-area culling in lowering fox abundance and predation pressure by foxes.

BIO. Lino is currently with the Chair of Wildlife Ecology and Management at the University of Freiburg in south-western Germany, where he is completing his PhD on the effectiveness of restricted-area fox culls while also conducting a research project with a wider focus. Apart from his doctorate work, Lino works for the State Forest Research Institute (FVA-BW) as a data analyst in a research project studying the effects of wind turbine development on capercaillie. Lino holds a Master’s degree in Environmental Science and a Bachelor in Wildlife Management. He is interested in applied ecological research with practical relevance at the interface of people and wildlife.
