Altering host-parasite interactions through wildlife conservation strategies. Disease outbreaks are heightened in endangered animals but strategies used to conserve these species often increase risk of disease; nowhere is this more critical than in species recovery programs. The project will study disease in a recovery program to improve conservation practice and protect Australia's wildlife, ensuring our ecosystems are sustained.
Latitudinal gradients and beyond: understanding the drivers of global patterns in plant ecology. There are astonishing gaps in our understanding of global patterns in the way plants grow, and the factors that underlie these patterns. We don’t know whether mean climatic conditions or extreme events are more important in shaping plant traits. We don’t know which environmental variables are most important in shaping most aspects of plant ecological strategy, and we don’t know what shape the relatio ....Latitudinal gradients and beyond: understanding the drivers of global patterns in plant ecology. There are astonishing gaps in our understanding of global patterns in the way plants grow, and the factors that underlie these patterns. We don’t know whether mean climatic conditions or extreme events are more important in shaping plant traits. We don’t know which environmental variables are most important in shaping most aspects of plant ecological strategy, and we don’t know what shape the relationship between latitude and most plant traits takes. This project will address these knowledge gaps, substantially improving our ability to predict the potential impacts of climate change on plants, and providing the basis for exciting new theory about the mechanisms driving the evolution of plant form and function in Australia, and around the world.Read moreRead less
Dimensions of ecological strategy for plants. A more fundamental understanding will be sought about the architecture and ecology of vegetation and why it varies around the world. Under a high- CO2 future, models will be needed that operate through fundamental mechanisms of evolution, competition and physiology, rather than through extrapolation from present-day plants.
Putting adaptation into vegetation models: towards a predictive theory of trait diversity and stand structure. By incorporating natural selection into models of vegetation, this project will help to predict what sorts of plants are found where and why. This will greatly improve the ability to predict the likely outcomes of human impacts (changing climates, increased disturbance, logging) for future vegetation and species diversity.

Summary
Evolutionary ecology of vegetation. A more fundamental understanding will be developed about the architecture and ecology of vegetation and why it varies around the world. Understanding confers benefits for land management as well as cultural value. Under a high carbon dioxide future scenario, models will be needed that operate through fundamental mechanisms of evolution, competition and physiology, rather than through extrapolation from present-day plants.

A more fundamental understanding will be developed about the architecture and ecology of vegetation and why it varies around the world. Understanding confers benefits for land management as well as cultural value. Under a high carbon dioxide future scenario, models will be needed that operate through fundamental mechanisms of evolution, competition and physiology, rather than through extrapolation from present-day plants. Australia is a leader in globalising plant trait ecology, and the program will develop that role further. Through intensive short courses within the Sydney basin and at national scale, research capacity will be developed towards the coming four-way fusion among functional ecology, earth system science, comparative genomics and palaeobiology.Read moreRead less
A framework linking tree species coexistence, zonation and patterns of species richness in forests. Our curiosity-driven proposal capitalizes on a superb opportunity afforded by the occurrence of forest vegetation across a wide range of climates and soils in eastern Australia, an ideal setting for testing ideas about how environment shapes plant evolution as well as forest structure and dynamics. This research will contribute to international interchange of ideas by promoting interaction with co ....A framework linking tree species coexistence, zonation and patterns of species richness in forests. Our curiosity-driven proposal capitalizes on a superb opportunity afforded by the occurrence of forest vegetation across a wide range of climates and soils in eastern Australia, an ideal setting for testing ideas about how environment shapes plant evolution as well as forest structure and dynamics. This research will contribute to international interchange of ideas by promoting interaction with collaborators in New Zealand, and will generate a series of publications in high-impact international journals. We will help Australians better understand the forces that shape patterns of woody vegetation across local landscapes, and our carbon-balance framework may shed light on the causes of rarity of some tree species with conservation problems.Read moreRead less
Latitudinal gradients in biotic processes affecting plant growth and establishment. The idea that plant-animal interactions are more intense in the tropics underpins much thinking about tropical ecology, global patterns in plant traits, and latitudinal gradients in biodiversity. In this project, we will provide the first direct and global test of this idea by quantifying the intensity of herbivory, seed predation and density-dependent seedling mortality at approximately 100 study sites around th ....Latitudinal gradients in biotic processes affecting plant growth and establishment. The idea that plant-animal interactions are more intense in the tropics underpins much thinking about tropical ecology, global patterns in plant traits, and latitudinal gradients in biodiversity. In this project, we will provide the first direct and global test of this idea by quantifying the intensity of herbivory, seed predation and density-dependent seedling mortality at approximately 100 study sites around the world. We will also investigate the causes of these latitudinal gradients by determining which environmental variables are most closely associated with the strength of biotic interactions.Read moreRead less
Mobility, stasis or extinction? The response of plants to long-term environmental change. This study of Australian plants will improve our ability to predict how plants and vegetation will respond to climate change by investigating the ability of plants to survive climate change. In particular, this project is designed to generate simple principles that can be used in management of species and vegetation at risk from climate change.
The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to unde ....The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to understand the genetic potential of organisms to adapt to anthropomorphic change in the environment connected with the resources industry. Our work, will bring new insight into the future management of environmental contamination, and the mitigation of adverse effects arising from resource extraction.Read moreRead less
Watching evolution in action using transitional forms of lizard pregnancy. By using newly developed epigenomic techniques and two Australian lizards that exhibit egg-laying, pregnancy and a rare transitional form of reproduction, this Project aims to watch “evolution in action” to determine how genetic changes enable the evolution of complex traits. The expected outcomes are a new synthesis of how genomic architecture underpins the transition from egg-laying to live-birth, and the first computat ....Watching evolution in action using transitional forms of lizard pregnancy. By using newly developed epigenomic techniques and two Australian lizards that exhibit egg-laying, pregnancy and a rare transitional form of reproduction, this Project aims to watch “evolution in action” to determine how genetic changes enable the evolution of complex traits. The expected outcomes are a new synthesis of how genomic architecture underpins the transition from egg-laying to live-birth, and the first computational model illustrating how transitional reproductive forms are maintained. The benefits include development of Australian expertise in state-of-the-art technologies, new international collaborations between the University of Sydney and Harvard, and significantly enhanced knowledge of vertebrate evolution and diversity.Read moreRead less
