Spatial patterns in estuarine fish faunas in tropical Queensland: a reflection of interaction between long-term physical and biological processes?

摘要: Spatial differences in the distribution and abundance of fish faunas structurally complex habitats subtidal areas three tropical estuaries were investigated by using modified Antillean-Z traps. The overall species compositions similar; however, differed substantially both within among estuaries. Although most declined an upstream direction, assemblages different similar. In contrast, seaward regions quite distinct. Neither temperature nor turbidity correlated with catch rates abundant species. some significantly deviation away from normal seawater salinity, cases correlation maximum salinity was much stronger. Thus, decreased catches absence common may be related to influence long-term (months years) patterns salinity. Some only one region a single creek. This reflect close proximity nearby which recruits come.
