“…Both species are at the extreme northern edge of their range in Cape Breton. Lusioglossum comugenense occurs much farther north than the study locality: it has been recorded north of the Arctic Circle (Sakagami and Toda 1986), but its biology has hitherto not been studied. Cape Breton is fairly central in the latitudinal range of true Lusioglossum laevissimum, which also extends across North America to the Pacific coast (G. C. Eickwort, personal communication).…”

Augochlorella striata, Lasioglossum (Evylaeus) cinctipes, Lasioglossum (Evylaeus) comagenense, and Lasioglossum (Dialictus) laevissimum were studied on Cape Breton Island, Nova Scotia, throughout their flight season in 1987. The weather during the summer was unusually good, with above-average temperatures and hours of sunshine but very low rainfall. Conversely, the previous summer had been very poor for bees, with comparatively few days suitable for foraging, particularly in July. Augochlorella striata was basically solitary but some nests produced one or, at most, two workers, thereby becoming eusocial. In other localities, L. cinctipes is known to be eusocial with well-developed morphological and physiological caste differentiation. However, most foundresses observed in 1987 were extremely small, smaller than usual for workers elsewhere, and none of the more than 100 nests produced adult workers or a reproductive brood. Most foundresses were either survivors of the worker brood from the previous year or unusually small reproductive brood females produced as a result of the bad weather in 1986. Lasioglossum comagenense was solitary or semisocial with one to four females occupying a nest. Lasioglossum laevissimum exhibited significant levels of pleometrosis and an extended period of worker foraging in summer. A comparison of the productivities of these four species indicates the importance of a flexible social system in a marginal climate.

“…Monitoring range limits for selected species (see also Marker Species below) would therefore indicate the rapidity of change. For example, species of several distinctive groups, such as solitary bees (Sakagami and Toda, 1986) and psyllids (Hodkinson, 1978), currently drop out at or near the tree line and might be instructive indicators.…”

Arctic Insects as Indicators of Environmental Change

ABSTRACT. The great diversity of terrestrial arthropods in the Arctic suggests that these organisms are especially useful to monitor environmental change there, where warming as a result of climatic change is expected to be especially pronounced and where current conditions are limiting for many organisms. Based on existing information about arctic faunas and how they differ from temperate ones, this paper suggests several elements, including ratios and other quantitative indexes, that can be used for long-term evaluations of change. These elements include composition indexes, range limits, marker species, interspecific ratios, relationship shifts, phenological and physiological indicators, and key sites. Using such elements in a planned way would exploit the diversity of arctic insects and emphasize their importance in arctic systems. Key words: arctic arthropods, arctic insects, arctic fauna, climatic change, environmental change, monitoring, indicator species, long-term research RÉSUMÉ. La grande diversité d'arthropodes terrestres dans l'Arctique suggkre que ces organismes se prêtent particulièrement bien à la surveillance des changements qui prennent place dans cet environnement, où l'on s'attend à un réchauffement assez prononcé suite aux changements climatiques et où les conditions actuelles sont défavorables à beaucoup d'organismes. En s'appuyant sur l'information actuelle concernant les espèces arctiques et la façon dont elles diffèrent des espèces tempérées, cet article propose divers Cléments, y compris des rapports et d'autres index quantitatifs, à utiliser pour effectuer une évaluation à long terme des changements. Ces Cléments comprennent les index de composition, les limites de territoire, les espkces repères, les rapports interspécifiques, les modifications des liens, les indicateurs phénologiques et physiologiques ainsi que les sites clés. L'utilisation planifiée de ces éléments permettrait d'exploiter la diversité des insectes arctiques et de souligner leur importance dans les systèmes arctiques.
