Experimental manipulation of the winter surface ice layer: the effects on a High Arctic soil microarthropod community
The effect of patch size on the tolerance of the soil microarthropod population to an experimentally induced environmental catastrophe, a thick surface ice layer, was studied at a High Arctic site (78°55 ‘N, 11°53’ E). Such an ice layer currently occurs infrequently; however, climate change models s...

The effect of patch size on the tolerance of the soil microarthropod population to an experimentally induced environmental catastrophe, a thick surface ice layer, was studied at a High Arctic site (78°55 ‘N, 11°53’ E).
