Caterpillars benefit from thermal ecosystem engineering by wandering albatrosses on sub-Antarctic Marion Island
Wandering albatrosses (Diomedea exulans) nest on Southern Ocean islands, building elevated nests upon which they incubate eggs and raise chicks, and which the chicks occupy through winter. The nests support high invertebrate biomass, including larvae of the flightless moth Pringleophaga marioni. Her...
