Experimental Test of the Effects of a Non‐Native Invasive Species on a Wintering Shorebird
Abstract: The abundance of nearly one‐quarter of the world's shorebird species is declining. At the same time, the number of non‐native species in coastal ecosystems is increasing rapidly. In some cases, non‐native species may affect negatively the abundance and diversity of shorebird prey spec...

At the same time, the number of non‐native species in coastal ecosystems is increasing rapidly. In some cases, non‐native species may affect negatively the abundance and diversity of shorebird prey species. We conducted an experimental study of the effects of the introduced European green crab (Carcinus maenas) on prey consumption by wintering Dunlin (Calidris alpina) in a central California estuary. We placed green crabs and Dunlin sequentially in field enclosures and measured changes in density of benthic invertebrate prey (e.g. polychaetes and small clams), Dunlin biomass, and gut contents of both Dunlin and crabs and observed foraging behavior of Dunlin. Green crabs significantly affected Dunlin foraging success through both direct and indirect multitrophic linkages. In enclosures with high densities of green crabs, crab foraging reduced the availability of polychaetes, and Dunlin consumed significantly fewer polychaetes compared with Dunlin in enclosures without crabs. High densities of green crabs were also associated with increased availability of small clams. Dunlin consumed significantly more small clams compared with Dunlin in enclosures without crabs. In our literature survey of studies of effects of non‐native invasive species on shorebirds, we found three prior experiments that addressed the effect of non‐native invasive species on shorebirds. Results of two of these studies showed positive direct effects of non‐native invertebrates on shorebirds, 1 showed negative direct effects of a non‐native plant on shorebirds through habitat conversion, and none showed indirect effects of non‐native invertebrates. We suggest future management of shorebirds explicitly examine how non‐native marine species, particularly invertebrates, directly and indirectly affect shorebirds .
