Dr Pieter Arnold
Research Fellow
Australian National University

Resilience and sensitivity of Australian native plants to increasing heat load

Biography

Pieter Arnold is a plant ecophysiologist and global change biologist with broad research interests. His research career has spanned many fields within ecology and evolution, where he investigates how organisms function and respond to environmental changes and challenges. Pieter's current primary research area is plant ecophysiology: determining how the form and functions of plants influences their capacity to tolerate thermal extremes and chronic suboptimal environments.
Prof. Jane Catford
Professor
ANU & KCL

Plant invasions and environmental change drive biodiversity loss in grasslands worldwide

Biography

Jane is a plant community ecologist with interests in biological invasions, environmental change and biodiversity. She currently holds a joint position at the Australian National University in Canberra and King's College London in the UK where she is Professor of Ecological Change. Thanks to an ARC Future Fellowship, she'll be moving to the Fenner School of Environment & Society at ANU "in full" in 2026.

Hawkesbury Institute For The Environment, Western Sydney University

Warming offsets productivity losses from high evaporative demand in C3 pasture grass

Biography

I am an ecosystem ecologist focusing on the interaction between plants and soil. Specifically, I am interested in the mechanisms that allow plants to adapt to environmental changes and how plant communities influence the impacts of climate and global change on ecosystem processes. With increasing variability in precipitation patterns and rising temperatures, understanding strategies for adaptation—often species-specific—has become a vital area of research. This knowledge is crucial for developing sustainable plant production systems in future climates. As a research fellow in the Pastures and Climate Extremes project, I study forage plant responses to predicted climate changes through both mesocosm and field-scale experiments. My primary methods involve trait-based and ecophysiological approaches to examine how plants adjust to changing environmental conditions.
Lisa Danzey
Phd Candidate
University Of Technology Sydney

Do elevated night-time temperatures during heatwaves help or hinder sub-alpine plant communities?

Biography

Lisa's research focuses on how vegetation in alpine ecosystems respond to extreme and variable environmental conditions that are becoming more intense and frequent. Lisa's PhD applies fundamental concepts in plant physiology, landscape ecology and biogeography to explore plant responses under natural conditions. Lisa's projects bring together methodologies of population genetics, manipulative in-situ experiments, field physiological and microclimatic measurements, and predictive modelling.
Dr Nic Delnevo
Research Scientist
Dbca

Future-proofing flora: Genomic insights for climate adaptation in Southwest Australia

Biography

Nicola Delnevo is an early career researcher with interests in applied genomics and population genetics for conservation research. He has also developed a strong background in plant ecological responses to climate change through research conducted in Northern Italy and in Norway.
Mr Matt Elmer
PhD Student
Monash University

Warm range margin populations are less genetically diverse in a native bee

Biography

Matt is a PhD student who is interested in studying how environments and evolutionary processes have shaped populations and species, and applying this information to predict how species will respond to climate change. He is particularly interested in integrative approaches that combine measures of key physiological traits, genomics, and ecological modelling to address questions in these research areas.
Mr Josh Nitschke
PhD student
Flinders University

An extreme climate event drastically shifted prey energy density in the Coorong

Biography

Josh is currently undertaking a PhD in ecology, examining the structure and functioning of food webs under varying environmental conditions. He is based in the Coastal Ecosystem Ecology Lab (CEEL) at Flinders University in Adelaide. He also works in data analytics for Invertebrates Australia, a non-profit committed to the conservation of Australian invertebrates. He is dedicated to understanding and protecting the often-forgotten little critters that underpin the healthy ecosystems we rely on. He digs worms, literally.
Inna Osmolovsky
Post-doc

Introducing the Interaction Opportunists Hypothesis: Biotic interactions may drive counterintuitive range shifts

Biography

I am a Postdoctoral Researcher at the Evolution and Ecology Research Centre at UNSW Sydney. I investigate how species shift their geographic ranges in response to climate change, with a particular emphasis on the role of biotic interactions in shaping these shifts. My research seeks to unravel why some species shift toward lower elevations, equatorward regions, or shallower waters, rather than simply tracking cooler climates.
