Predator-prey relationships on islands are often profoundly altered by invasive species. Brown skuas Catharacta antarctica are predator-scavengers at sub-Antarctic islands, where their population dynamics are linked to food availability. On Marion Island, skua population size and breeding distribution appear to have shifted in response to changes in burrowing petrel populations, which were severely impacted by feral cat Felis...

Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char ( Salvelinus alpinus )—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous life‐history type supporting many subsistence and small‐scale commercial fisheries...

Coastal wetlands are being transformed by global change, impacting the ecological and societal benefits provided by these ecosystems. Synthesizing knowledge of historical and expected future transformations in coastal wetlands can help inform forward-looking planning and stewardship efforts. Here, we review anticipated future ecological transformations in coastal wetlands of the conterminous United States and contrast them wit...
