Population Dynamics of a Riverine Shrimp: Paratya australiensis (Kemp, 1917) in an Urban Landscape

(2010 – current)
Tony Lovell (University of Melbourne)

Paratya australiensis occurs commonly in rural streams throughout the south-central region of Victoria. Within the Melbourne metropolitan area, it occurs in urbanised streams of the dry, basalt plains north-west of Melbourne, but is absent or rare from the wetter metropolitan streams of more variable geology to the east and south. This unusual distribution suggests an interaction between catchment influences of climate, geology and urbanization in factors driving the distribution and abundance of the species.

This project will explore these interactions, first testing for genetic and morphological differences between the two populations, then assessing interactions of Paratya with other species, and the physical and chemical effects of stormwater and other urban impacts on population dynamics.

This research will  feed into the Little Stringybark Creek project, within the Ecosystem Dynamics Program, which aims to protect and restore a stream (Little Stringybark Creek) through stormwater harvesting, integrated with stormwater filtration and infiltration techniques.  See the Little Stringybark Creek Section of this website for more information on this research program.
