Environmental and ecological changes associated with a marina.

摘要: Anthropogenic modifications to waterways are common and their ecological consequences must be understood effectively conserve local biodiversity. The facilitation of recreational boating activities often requires substantial alteration natural areas, however the environmental such alterations rarely described in scientific literature. In this study, physico-chemical conditions were investigated a marina, located inside marine park on south-east coast Australia. Recruitment panels deployed for 8 weeks both outside differences composition developing fouling communities observed. recruitment taxa, which have short-lived larvae, was increased marina (bryozoans, spirorbids sponges) while longer-lived reduced or absent (barnacles, solitary ascidians non-spirorbid polychaetes). Differences also observed cf. directly outside. environment had higher turbidity, temperature pH along with concentrations lead copper suspended sediments, flow rates trapped sediment loads marina. study suggest that there may marked changes associated developments. potential these should primary consideration during planning process, particularly developments locations notable value.
