Sažetak:

The rate of urbanisation in many regions across the globe is accelerating and is predicted to continue well into the late 21^st century. Such urbanisation is drastically altering the conditions of aquatic habitats such as streams and lakes within those areas. Streams are easily influenced by changes to the surrounding land use, thus the reduction of riparian vegetation and more point and diffuse source pollutant inputs create a physically, chemically and ecologically altered system that has consequences for the taxonomic and functional composition of resident macroinvertebrate communities. Such changes alter the dynamics and flow of nutrients and energy through the entire food web. Using stable isotope ratios of ¹²C/¹³C and ¹⁴N/¹⁵N in whole tissues of macroinvertebrates and potential food sources, we can estimate how urbanisation may be changing the delicate balance of these food webs.
