Colonization history of Metrioptera roeselii in northern Europe indicates human‐mediated dispersal

Journal of Biogeography, 2012
AbstractAimThe bush‐cricket Metrioptera roeselii is an example of an insect which has expanded its indigenous range beyond expectations based on its natural dispersal potential. Understanding how species colonize new areas is vital for formulating effective species conservation programmes and managing invasive species.

Effect of temperature on spontaneous interneuron activity in grasshoppers Tettigonia cantans and Metrioptera roeselii (Orthoptera, Tettigoniidae)

Journal of Evolutionary Biochemistry and Physiology, 2006
Using electrophysiological methods, effects of temperature on rhythmic impulsation of spontaneously active neurons of thoracic ganglia was studied in grasshoppers Tettigonia cantans and Metrioptera roeselii. Several types of response to temperature changes were observed.

Changes in land use and habitat availability affect the population genetic structure of Metrioptera roeselii (Orthoptera: Tettigoniidae)

Journal of Insect Conservation, 2008
The impact of temporal changes in habitat availability and land use on the present genetic diversity of the grassland katydid species Metrioptera roeselii was investigated in an extensively used agricultural landscape (Lahn-Dill-Bergland, Germany) based on six microsatellite loci.

Limited gene flow may enhance adaptation to local optima in isolated populations of the Roesel’s bush cricket (Metrioptera roeselii)

Journal of Evolutionary Biology, 2010
AbstractVariation in morphological traits along latitudinal gradients often manifests as size clines. In insects, both positive and negative correlations are seen, and the mechanism behind the response is unclear. We studied variation in seven morphological traits of Roesel’s bush cricket,Metrioptera roeselii, sampled from seven latitude‐matched‐pair ...

SOME OBSERVATIONS ON METRIOPTERA ROESELII (GRYLLOPTERA: TETTIGONIIDAE) IN MAINE, NEW HAMPSHIRE, AND MASSACHUSETTS

The Canadian Entomologist, 1974
AbstractMetrioptera (Roeseliana) roeselii (Hgb.) was first introduced into the Montreal, Que., area before 1952. By 1965 it had been collected in western and southern New York State. This paper records it from Maine, Massachusetts, and New Hampshire for the first time, and discusses the populations. Eventual establishment of M. roeselii over all of New
