ON THE OCCURRENCE OF A CONTINENTAL ELEMENT IN THE GROUND-BEETLE FAUNA OF EASTERN CANADA (COLEOPTERA: CARABIDAE)
Published online by Cambridge University Press: 31 May 2012
Abstract
Several species of ground-beetles, with main area in the interior of North America, have more or less isolated occurrences in eastern Canada. Some of them have clearly expanded their area in recent years and are no doubt late immigrants into the east; others may be old relicts. The geographical instability of the former group is explained as an eastward movement of a steppe element following the deforestation of the country, notably within the U.S.A., south of the Great Lakes.
