Continent-wide risk assessment for the establishment of nonindigenous species in Antarctica
Invasive alien species are among the primary causes of biodiversity change globally, with the risks thereof broadly understood for most regions of the world. They are similarly thought to be amongExpand

Human activities, ecosystem disturbance and plant invasions in subantarctic Crozet, Kerguelen and Amsterdam Islands
Abstract Recent floristic surveys of the French islands of the southern Indian Ocean (Ile de la Possession, in the Crozet archipelago, Iles Kerguelen and Ile Amsterdam) allow a comparison of theExpand

Variable temperature effects of Open Top Chambers at polar and alpine sites explained by irradiance and snow depth.
Environmental manipulation studies are integral to determining biological consequences of climate warming. Open Top Chambers (OTCs) have been widely used to assess summer warming effects onExpand

The significance of the sub-Antarctic Kerguelen Islands for the assessment of the vulnerability of native communities to climate change, alien insect invasions and plant viruses
The suite of environments and anthropogenic modifications of sub-Antarctic islands provide key opportunities to improve our understanding of the potential consequences of climate change andExpand

Recovery of native plant communities after eradication of rabbits from the subantarctic Kerguelen Islands, and influence of climate change
The introduction of rabbits in 1874 into the Kerguelen archipelago had a significant impact on plant communities: the most sensitive species Pringlea antiscorbutica and Azorella selago disappearedExpand

Microclimate impacts of passive warming methods in Antarctica: implications for climate change studies
Passive chambers are used to examine the impacts of summer warming in Antarctica but, so far, impacts occurring outside the growing season, or related to extreme temperatures, have not been reported,Expand

Variation of morphometric traits in populations of an invasive carabid predator (Merizodus soledadinus) within a sub-Antarctic island
Invasive predators may change their own trophic conditions by progressively displacing or reducing diversity and abundance of native prey. As food quality and quantity are two main factorsExpand

Food for thought: Risks of non-native species transfer to the Antarctic region with fresh produce
To understand fully the risk of biological invasions, it is necessary to quantify propagule pressure along all introduction pathways. In the Antarctic region, importation of fresh produce is aExpand

Is dispersal promoted at the invasion front? Morphological analysis of a ground beetle invading the Kerguelen Islands, Merizodus soledadinus (Coleoptera, Carabidae)
As a biological invasion proceeds, the spread of the alien may promote dispersal ability at the front by direct and indirect selection, thereby altering the dynamics of the invasion. MorphologyExpand
