Female roles during postcopulatory sexual selection. The project will evaluate the importance of postcopulatory sexual selection in the guppy, a polyandrous species of livebearing fish. The use of artificial insemination, which experimentally controls the relative contribution of sperm from competing males (as well as other confounding effects), will facilitate a powerful test of recent theoretical predictions in evolutionary biology.

The project will evaluate the importance of postcopulatory sexual selection in the guppy, a polyandrous species of livebearing fish. The use of artificial insemination, which experimentally controls the relative contribution of sperm from competing males (as well as other confounding effects), will facilitate a powerful test of recent theoretical predictions in evolutionary biology. The project will enable me to distinguish between competing hypotheses for postcopulatory paternity bias following female multiple mating (sperm competition, cryptic female choice, genetic compatibility) and provide additional insights into the selective forces promoting the evolution of female promiscuity.Read moreRead less

Summary
High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality c ....High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality changes, pollution histories, recent geomorphological change, land-use change, introduction of invasive species and the occurrence of bushfires. A better understanding of the occurrence and timing of these major environmental issues is of national and regional importance.Read moreRead less
