To test this theory, we developed a food web model using stable isotopes (d13C, d15N) for the high-latitude Vestfold Hills shallow-water benthic community and compared it to the isotopic food web model developed for the Windmill Islands, located over 1000 km away. For the Vestfold Hills food web, carbon sources were generally well separated by d13C, and lower-order consumers could be grouped according to their feeding guild and main dietary sources as determined by d13C and d15N. Higher-order consumers occupied the full range of d13C ratios and had similar d15N values, although predators were weakly, but significantly, enriched in d15N compared to scavenger/predators and omnivores. When comparing with the Windmill Islands food web, we found similar d13C ratios for several co-occurring carbon sources and consumers, whilst the d15N ratios in consumers from the Vestfold Hills were consistently enriched compared to those from the Windmill Islands by 1 to 2‰. The relative positions of feeding guilds on the d13C and d15N planes were similar for both food webs. These results suggest there is considerable merit in developing a representative food web model for Antarctic shallow-water communities. Such a model would provide a trophic benchmark against which modification in these communities brought about by climate change or other human impacts could be compared.Progress Code: completedStatement: The original datasheet was reformatted to fit IPT Biodiversity.AQ standard.

From the abstract of the referenced paper:

Shallow-water benthic communities throughout coastal Antarctica share many species and are governed by similar physico-oceanographic processes. This suggests community structure and function may be similar among communities despite being geographically separated by up to 15 degrees of latitude and 18000 km of coastline. To test this theory, we developed a food web model using stable isotopes (d13C, d15N) for the high-latitude Vestfold Hills shallow-water benthic community and compared it to the isotopic food web model developed for the Windmill Islands, located over 1000 km away. For the Vestfold Hills food web, carbon sources were generally well separated by d13C, and lower-order consumers could be grouped according to their feeding guild and main dietary sources as determined by d13C and d15N. Higher-order consumers occupied the full range of d13C ratios and had similar d15N values, although predators were weakly, but significantly, enriched in d15N compared to scavenger/predators and omnivores. When comparing with the Windmill Islands food web, we found similar d13C ratios for several co-occurring carbon sources and consumers, whilst the d15N ratios in consumers from the Vestfold Hills were consistently enriched compared to those from the Windmill Islands by 1 to 2‰. The relative positions of feeding guilds on the d13C and d15N planes were similar for both food webs. These results suggest there is considerable merit in developing a representative food web model for Antarctic shallow-water communities. Such a model would provide a trophic benchmark against which modification in these communities brought about by climate change or other human impacts could be compared.
