Speaker

Chloe Bentze
Phd Student
University Of South Australia

Using in situ microrefugia to safeguard stringybark eucalypts from hot droughts

Biography

I am a third-year PhD student at the University of South Australia, interested in biodiversity conservation and forest ecosystem response to anthropogenic change.
Dr Cal Bryant
Post-doc
Australian National University

Understanding and responding to climate change-mediated subalpine snow-gum woodland decline

Biography

Cal Bryant is an ANU-based post-doctoral researcher on the mitigation program of the Save Our Snow-gum ARC Linkage Project, led by Adrienne Nicotra, partnered with NSW DPIE, NSW NPWS, VIC PARKS, and ACT EPSDD. Cal also convenes the Dieback and Climate-Succession Network - an interdisciplinary, voluntary network of professionals working on research and responses to vegetation dieback and climate-driven vegetation change in Australia. The DCSN aims to foster collaboration and exchange between researchers, land managers, afforestation/ restoration NGOs and state environment departments to promote the uptake, research, and development of effective responses to dieback and climate-driven change in Australian ecosystems. The network hears from two presenters monthly. Cal also care-takes a 4000-acre Box-Gum Woodland on the Monaro tablelands, Ngarigo country.
Mr. Lachlan Byrnes
Phd Candidate
Yale University

Edge effect driven tree mortality drives community change in the Amazon-Cerrado edge

Biography

Lachlan Byrnes received his undergraduate degree in Honours Ecology from the University of British Columbia. While at UBC, he became interested in using plant ecophysiological traits to understand forest disturbance while working in the Michaletz Lab. His dissertation focuses on using ecophysiological traits to explain the changes in fortest structure and function in forest edges. These projects focus on the Amazon-Cerrado region, along the “Arc of Deforestation”. Lachlan’s current projects look at how plant water-use, access to water, and resource allocation can influence mortality in forest edges and as a result change forest structure and function over time.
Weerach Charerntantanakul
Phd Student
The Australian National University

Remote sensing shows that mature, long-unburnt snow-gum woodlands are declining

Biography

Weerach is a PhD student and Fenner School of Environment and Society, the Australian National University, ACT. His research focuses on applications of remote sensing technologies in mapping snow gum dieback in Australian subalpine woodlands. His works are part of a bigger project that looks at snow-gum dieback phenomena through multiple research approaches, from assessing the values of these woodlands to modeling future scenarios in response to climate change.
Prof Brendan Choat
Professor
Western Sydney University

Realtime sensor networks for monitoring ecological processes

Biography

Brendan Choat is a Professor at the Hawkesbury Institute for the Environment, Western Sydney University. He studies plant ecology with a focus on how climate change is affecting Australian forest and woodland ecosystems. This includes understanding the physiological tolerance of Australian tree species to extreme water stress and heat stress. His recent work covers the response of forests to the record 2019/20 drought and bushfires in south eastern Australia. Prof. Choat has held previous roles at Harvard University, the University of California, and the Australian National University. He was awarded a prestigious Alexander von Humboldt Fellowship in 2010 that allowed him to work in Germany for two years. In 2014, he was awarded an ARC Future Fellowship for his work on mapping drought response in trees. Prof. Choat has more than 125 peer-reviewed publications including articles in top-ranked international journals Nature, Science, and PNAS.
Mads Dwyer
Masters Candidate
La Trobe University

Shaded out or in the dark? Potential recovery routes for invaded heathlands.

Biography

Mads Dwyer is a master's candidate at La Trobe University, in Melbourne (Naarm), Australia. Following the first year of their masters, during which their research was centered around the biogeographic drivers of Coast Tea Tree’s invasion into sand heathland communities, Mads’ research has shifted to the heathland communities themselves, with a focus on determining the community’s ability to recover from said invasion. Outside of their research, Mads is involved in environmental education, floristic surveying and ecological restoration, and has enjoyed getting to know other systems, including grassland communities.
Mr Ryan Fisher
Ecologist / Researcher
Stantec / University Of Melbourne

Assessing Morphological Leaf Traits, and Hydraulic Vulnerability in Eucalyptus Species

Biography

Ryan completed his Masters of Environment at the University Of Melbourne prior to entering the ecological consulting industry as a botanist. Ryan has returned (Part time) to the research world to collect additional data for this research topic to increase the validity and robustness of his completed thesis. Ryan is a passionate ecologist, specialising mostly in botany (who doesn't love a quadrat!). However has extensive hands-on and research experience in various other ecological surveys. Ryan is an overtly proud queer and autistic person who aims to connect with people within the industry and community.
Ms Donna Fitzgerald
Phd Candidate
University Of South Australia

Analysis of eucalypt dieback: Fusion of spectral and structural aerial imagery data

Biography

Donna Fitzgerald holds a Bachelor’s Degree in Environmental Science, from the University of South Australia (Uni SA) with First-Class Honours. Donna is now completing her PhD at the University of South Australia. During her PhD, Donna has been developing methods for reviewing the dieback of eucalypt forests using various remote sensing methods, using aerial and satellite imagery. Two of her PhD chapters have now been published ( https://doi.org/10.3390/land12071271 and http://dx.doi.org/10.1111/aec.70061). During her PhD, Donna has been awarded the Playford Memorial Trust PhD Scholarship, The Peter Woodgate Scholarship for Earth Observation, SmartSat CRC scholarship for NASA JPL internship and the Maurice De Rohan International Scholarship.
