Modelling Approach

This study adopts a spatial perspective to analyse the complex commuting patterns of the Beijing metropolitan region. By combining measures of the built environment, neighbourhood characteristics and development time periods, a four-fold neighbourhood classification was derived by cluster analysis to reflect different urbanisation contexts. Commuting flows were mapped to illustrate the spatial mismatch of home–work locations during the rampant urbanisation process. The novel use of a multilevel modelling approach shows how individual socio-economic attributes and neighbourhood factors, and their interactive effects, explain the varied commuting patterns. The cross-level interactions of variables highlight the predominant influence of individual attributes, which also interact with locational conditions of neighbourhood with differential explanatory power, on commuting patterns.

And Control

The impacts of river regulation on aquatic biota have been extensively studied, but long-term assessments of the restoration of biota by environmental flows and the principal mechanisms of recovery have rarely occurred. We assessed whether the provision of an environmental flow regime (EFR) via the decommissioning of an aqueduct on a tributary stream altered downstream macroinvertebrate assemblages in the highly regulated Snowy River, Australia. Macroinvertebrate assemblages of the Snowy River, reference and control sites remained distinct despite the provision of environmental flows. Invertebrate assemblages detrimentally affected by regulation probably remained impaired due to either constraints on colonisation from the tributary stream (dispersal constraints) or unsuitable local environmental conditions in the Snowy River caused by flow regulation (e.g. high levels of fine sediments, elevated temperature regime) suppressing new colonists or recovery of extant populations. Our study showed that restoration may be ineffective if EFRs are too small to ameliorate local environmental factors constraining the recovery of affected biota. Other barriers to recovery, such as dispersal constraints, also need to be overcome. Successful restoration of regulated rivers using environmental flows requires an understanding of the mechanisms and pathways of recovery, together with identification and amelioration of any potential barriers to recovery.
