Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the ....Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the minimum population sizes and habitat areas required for long-term survival. My prior research has validated the predictive accuracy of PVA. This research will deliver practical guidelines for managing threatened species.Read moreRead less
Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by provid ....Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by providing evidence-based support for minimum viable population size targets to avoid extinction; (2) responding to climate change by determining the species- and environmentally specific contexts leading to elevated risks of extinction; and (3) protecting Australia from invasive diseases and pests by determining density targets that maximise eradication success.Read moreRead less
