![]() ![]() This study contributes to the understanding of human influences on southwest Australian plant taxa that have been present since the late Pleistocene, but to date have received little scientific attention. ![]() trachymenioides over the southeastern part of its range are consistent with anthropogenic influences. In contrast, higher gene flow estimates, less divergence between populations and common haplotypes in P. Platysace effusa showed a pattern of high population divergence, low gene flow and multiple refugia, consistent with a long evolutionary history, past climatic oscillations and persistence in a highly fragmented landscape. We found differences between utilized and non-utilized taxa, particularly when considered against the generally complex phylogeographical patterning in southwest Australian plant taxa. Edible tubers of Platysace deflexa and Platysace trachymenioides have been harvested historically by Noongar traditional owners, whereas Platysace effusa has no known cultural significance. We examined variation in geographical structure and gene flow estimates based on three non-coding regions of plastid DNA in three southwest Australian members of the Platysace genus to identify whether a human influence on dispersion of utilized taxa was detectable. High gene flow and a population structure corresponding to human rather than geographical drivers are likely to be genetic patterns of human-dispersed plant taxa. This study contributes to the understanding of human influences on south-west Australian plant taxa that have been present since the late Pleistocene, but to date have received little scientific attention. trachymenioides over the south-eastern part of its range are consistent with anthropogenic influences. We found differences between utilized and non-utilized taxa, particularly when considered against the generally complex phylogeographical patterning in south-west Australian plant taxa. We examined variation in geographical structure and gene flow estimates based on three non-coding regions of plastid DNA in three south-west Australian members of the Platysace genus to identify whether a human influence on dispersion of utilized taxa was detectable. On this basis we propose the existence of an Eastern Noongar rock art tradition. The analysis seeks to determine the prominent formal characteristics of the art at Marbaleerup and Boyatup: do they share some or all of the characteristics of Noongar rock art? The results suggest that Esperance Nyungar rock art is consistent with that clustered around the north-eastern periphery of Noongar country. The peripheral location of the Esperance Nyungar lands and their proximity to neighbouring non-Noongar groups gives rise to questions about how its rock art compares to other Noongar rock art. ![]() The Esperance region lies at the eastern edge of the traditional lands of the Noongar people, a language and landholding group who occupy the southwest corner of the Australian continent - Noongar country. This paper presents a formal analysis of the two known rock art sites in the Esperance region of Western Australia - Marbaleerup and Boyatup - and compares and contrasts them with the characteristics of 43 other known rock art sites in the Noongar lands. ![]()
