Range expansion pattern of Carabus granulatus Linnaeus, 1758 (Coleoptera: Carabidae) in eastern North America and a new northern range record

Abstract

The invasion history of alien Prosopis (mesquite) in Israel and Jordan is presented, with a detailed description of the introduction, background and the habitats now infested with Prosopis in these countries. While the number of escaped individuals in Israel is still limited, Prosopis has invaded large areas in Jordan and has become the main invasive alien tree in the Jordan valley. It is also now spreading in the canyons of south Jordan. The distinct prosopis invasion patterns in Israel and Jordan are discussed. Control programs are urgently needed in order to contain the proliferation of Prosopis, which now poses a major threat to natural habitats as well as to fallow fields. The ongoing establishment of dense thickets of Prosopis along wadis with year-round water flow is likely to displace native species such as Acacia raddiana Savi, and to alter the function of natural ecosystems.

New records and range extensions of Carabidae of Ontario’s boreal forest

“…We found eight species not native to North America, including the two nonnative species discussed above (species new to Ontario) and one, Carabus granulatus, discussed in Fleming and Beresford (2017). Of the remaining five species, three species exhibited range extensions, one species had gap infills (i.e., in the interstices of its known range), and the remaining species, Clivina fossor, was found within its known range.…”

“…In total, 644 specimens were collected from 112 sites across Northern Ontario (Table 2; Fig. 1; see Fleming and Beresford 2017 for Carabus granulatus and Fleming and Beresford 2019 for Elaphrinae). There were 335 specimens collected as part of the Far North Biodiversity Project, of which six were damaged and could not be identified.…”

“…Including specimens first reported elsewhere, Carabus granulatus (Fleming and Beresford 2017), and five species of Elaphrinae (Fleming and Beresford 2019), we identified 638 specimens representing 105 species from 31 genera that were collected from Ontario's Far North. Of these 105 species, one species was new to Canada, 11 species were new to Ontario (including the species new to Canada), and 70 range extensions at least 100 km from known range limits were identified.…”

“…Entries represent the number of specimens. For Carabus granulatus, seeFleming and Beresford (2017) and for the five species of Elaphrinae, seeFleming and Beresford (2019).…”
