The spatial energetics of pollination failure in habitat restoration. This project addresses the reasons for pollination failure of threatened plant species during habitat restoration. Specifically, the project will determine the role of energetic constraints on pollinator movement in the hostile landscape matrix surrounding urban woodland remnants, and model future scenarios for restoring natural functioning woodland ecosystems.
Ants, plants, diversity and function: trophic interactions and ecosystem function in a large-scale restoration experiment. Food and clean water are but two of the benefits we reap from functioning ecosystems, but we know little about how individual species contribute to making ecosystems work. This project capitalises on the diversity of Australia's ant fauna by using ants as a model taxon to explore the link between biodiversity and ecosystem functioning.
Fire regimes and demographic responses interact to threaten woody species. This project aims to extend and test an Interval Squeeze conceptual model which predicts fire-climate interaction effects on plant species persistence. Complex processes affect future species persistence, and an evidence-based conceptual framework is needed. Working across two continents, this project will quantify the effects of projected shortening of fire intervals, lower rainfall and elevated temperatures on woody pla ....Fire regimes and demographic responses interact to threaten woody species. This project aims to extend and test an Interval Squeeze conceptual model which predicts fire-climate interaction effects on plant species persistence. Complex processes affect future species persistence, and an evidence-based conceptual framework is needed. Working across two continents, this project will quantify the effects of projected shortening of fire intervals, lower rainfall and elevated temperatures on woody plant species. Field evidence spans global change predictions, ecosystems and species representing key system dominants and functional response types. The project will synthesise this data into larger simulation models and extend its conceptual framework to directly inform conservation and fire management.Read moreRead less
Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competit ....Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competitors. Toad tadpoles produce chemicals that have devastating effects on younger members of their own species, but not on native species. By deploying those chemicals, this project could develop a novel and powerful form of invader control.Read moreRead less
