Climate change helps polar invasives establish and flourish: evidence from long-term monitoring of the blowfly Calliphora vicina

Long-term meteorological monitoring (temperature, precipitation, snow, sun) at the Kerguelen Islands (Port aux Français). The files also report the invasion trajectory of the blowfly <em>Calliphora vicina</em> Robineau-Desvoidy (1830) from the sub-Antarctic Kerguelen Islands. In the 1970s, it is thought to have persisted only in sheltered microclimates for several decades. The phenology and invasion dynamics was monitored at the Kerguelen Islands since it has been first recorded using baited traps and opportunitic observation from 1978 onwards.
