Modelling the distribution of the invasive Roesel’s bush-cricket (Metrioptera roeselii) in a fragmented landscape [PDF]
NeoBiota, 2011 The development of conservation strategies to mitigate the impact of invasive species requires knowledge of the species ecology and distribution. This is, however, often lacking as collecting biological data may be both time-consuming and resource ...

Sexual selection on bushcricket genitalia operates in a mosaic pattern. [PDF]
Ecol Evol, 2020 In most species with internal fertilization, male genitalia evolve faster than other morphological structures. This holds true for genital titillators, which are used exclusively during mating in several bushcricket subfamilies.

Gene flow relates to evolutionary divergence among populations at the range margin [PDF]
PeerJ, 2020 Background Morphological differentiation between populations resulting from local adaptations to environmental conditions is likely to be more pronounced in populations with increasing genetic isolation. In a previous study a positive clinal variation in

Does wing dimorphism affect mobility in Metrioptera roeselii (Orthoptera: Tettigoniidae)? [PDF]
European Journal of Entomology, 2011 Range shifts are among the most conspicuous effects of global warming. Marked changes in distribution are recorded both for highly mobile species of insects, which are capable of flight, and wing-dimorphic species with predominantly short-winged ...

Two Species with an Unusual Combination of Traits Dominate Responses of British Grasshoppers and Crickets to Environmental Change. [PDF]
PLoS ONE, 2015 There are large variations in the responses of species to the environmental changes of recent decades, heightening interest in whether their traits may explain inter-specific differences in range expansions and contractions.

Evaluating range-expansion models for calculating nonnative species' expansion rate. [PDF]
Ecol Evol, 2014 Species range shifts associated with environmental change or biological invasions are increasingly important study areas. However, quantifying range expansion rates may be heavily influenced by methodology and/or sampling bias. We compared expansion rate

Genetic diversity of a successful colonizer: isolated populations of Metrioptera roeselii regain variation at an unusually rapid rate. [PDF]
Ecol Evol, 2014 AbstractNewly founded isolated populations need to overcome detrimental effects of low genetic diversity. The establishment success of a population may therefore depend on various mechanisms such as assortative mating, purging of deleterious alleles, creation of new mutations and/or repeated inflow of new genotypes to reduce the effects of inbreeding ...

Copulatory courtship by internal genitalia in bushcrickets. [PDF]
Sci Rep, 2017 Male genital organs are among the fastest evolving morphological structures. However, large parts of the male’s genitalia are often hidden inside the female during mating.

Dynamics of Reintroduced Populations of Oedipoda caerulescens (Orthoptera, Acrididae) over 21 Years. [PDF]
J Insect Sci, 2017 Conservation programs increasingly involve the reintroduction of animals which otherwise would not recolonize restored habitats. We assessed the long-term success of a project in which the Blue-winged grasshopper, Oedipoda caerulescens (L., 1758), was ...

What triggers colour change? Effects of background colour and temperature on the development of an alpine grasshopper. [PDF]
BMC Evol Biol, 2015 BackgroundColour polymorphisms are a fascinating facet of many natural populations of plants and animals, and the selective processes that maintain such variation are as relevant as the processes which promote their development.
