BACKGROUND The success of human societies depends intimately on the living components
of natural and managed systems. Although the geographical range limits of species are …

Antarctic terrestrial biodiversity occurs almost exclusively in ice-free areas that cover less than
1% of the continent. Climate change will alter the extent and configuration of ice-free areas…

Globally, collapse of ecosystems—potentially irreversible change to ecosystem structure,
composition and function—imperils biodiversity, human health and well‐being. We examine …

Plants collected from diverse sites on subantarctic Macquarie Island varied by up to 30‰ in
their leaf δ 15 N values. N natural abundance of plants, soils, animal excrement and …

The Antarctic Treaty System, acknowledged as a successful model of cooperative regulation
of one of the globe's largest commons ( 1 ), is under substantial pressure. Concerns have …

Millions of birds migrate to and from the Arctic each year, but rapid climate change in the
High North could strongly affect where species are able to breed, disrupting migratory …

Antarctica is widely regarded as one of the planet's last true wildernesses, insulated from
threat by its remoteness and declaration as a natural reserve dedicated to peace and science. …

Antarctic biodiversity faces an unknown future with a changing climate. Most terrestrial biota
is restricted to limited patches of ice‐free land in a sea of ice, where they are adapted to the …

Biological invasion is one of the key threats to the conservation of the broader Antarctic
region. We provide an evidence-based assessment of the status of biological invasion in the …

Environmental conditions and plant size may both alter the outcome of inter‐specific plant–plant
interactions, with seedlings generally facilitated more strongly than larger individuals in …
