Developing biogeographic know-how: Improving species divergence and dispersal estimations to examine geological and climatic evolutionary drivers. Anthropogenic activity over the last 150 years is now dramatically changing our global climate and ecosystems. The impact on biodiversity is already evident, and large-scale floral and faunal extinctions are predicted. This study unites a cohort of international experts in an interdisciplinary team to develop new molecular and mathematical methods to ....Developing biogeographic know-how: Improving species divergence and dispersal estimations to examine geological and climatic evolutionary drivers. Anthropogenic activity over the last 150 years is now dramatically changing our global climate and ecosystems. The impact on biodiversity is already evident, and large-scale floral and faunal extinctions are predicted. This study unites a cohort of international experts in an interdisciplinary team to develop new molecular and mathematical methods to expand our fundamental knowledge on how geological and global climate change have affected our world's species components and ecosystems in the past. This research is of environmental significance and global importance as it will improve our ability to predict how species behave under future predicted climate scenarios.Read moreRead less
The ancient symbiosis of crayfish and temnocephalan flatworms in Australian freshwaters investigated using molecules, morphology and biogeography. Freshwater parastacid crayfish are widespread and diverse in Australia's freshwaters. Associated with them (living on external surfaces) since their origins on Gondwana are very many species of temnocephalan flatworms. We will elucidate the molecular, morphological and biogeographic history of this association which appears to be ancient and specific. ....The ancient symbiosis of crayfish and temnocephalan flatworms in Australian freshwaters investigated using molecules, morphology and biogeography. Freshwater parastacid crayfish are widespread and diverse in Australia's freshwaters. Associated with them (living on external surfaces) since their origins on Gondwana are very many species of temnocephalan flatworms. We will elucidate the molecular, morphological and biogeographic history of this association which appears to be ancient and specific. The study will shed light on Australia's biological links with New Zealand and South America. It will also use the association between crayfish and temnocephalans as a model to investigate general features of symbioses, including molecular and morphological evolutionary responses and phenomena such as host-switching and cospeciation.Read moreRead less

Summary
Biodiversity, biogeography and molecular evolution on tropical reefs. This project aims to discover how evolutionary processes, biogeography and molecular change drive biodiversity patterns. Coral reefs support over 800,000 plant and animal species on <0.1% of the ocean. This project will examine how this biodiversity was formed by generating genomic data for reef building corals and reef associated fishes to reconstruct their evolutionary history. It will compare models of speciation, extinctio ....Biodiversity, biogeography and molecular evolution on tropical reefs. This project aims to discover how evolutionary processes, biogeography and molecular change drive biodiversity patterns. Coral reefs support over 800,000 plant and animal species on <0.1% of the ocean. This project will examine how this biodiversity was formed by generating genomic data for reef building corals and reef associated fishes to reconstruct their evolutionary history. It will compare models of speciation, extinction and range change among regions to determine how those processes contribute to the formation of biodiversity gradients and regional assemblage differences. The project expects that better understanding of evolutionary dynamics will inform conservation priorities.Read moreRead less
