Managing fragmentation and connectivity in River systems

"June 2005".

Project Number: MDRFC Project number M/03/2024 - CRCFE Project number B.250.

MDFRC item.

Project objectives a) To determine how populations of stream and river organisms are connected at different spatial and temporal scales in the landscape and to identify natural barriers to dispersal for a range of species, using modern genetic techniques. In addition, we wished to be able to predict, for a range of species, the scales at which natural recolonization would be expected in restored sites. b) To predict the impacts of disruption to natural patterns of connectivity, such as altered flow conditions and artificial barriers, on species with a range of dispersal abilities and in different landscape settings. c) To use fish as models to test hypotheses about current dispersal patterns arising from genetic data, by assessing evidence from otoloith microchemistry.
