Evaluating barriers to dispersal: weirs and tributaries in the montane rivers of the Australian alps
Funding: NSW Office of Water, Holsworth Wildlife Research Grant
Andrew is investigating the effects that weir walls and weir pools have on the dispersal of stream invertebrates. When weirs are over-topped, are invertebrates able to disperse over weir walls downstream to recolonise degraded sections of rivers? Do tributaries below dams offset the effects of regulation by supplying new colonists?
Dynamics of CPOM in Hughes Creek
Arturo is investigating the routes (by wind and water) by which terrestrially sourced leaves, bark and wood end up in Hughes Creek, the sizes of detritus patches that result, and the implications this has for invertebrate communities in the creek.
