Green‐brown polymorphism in alpine grasshoppers affects body temperature
Ecology and Evolution, 2020 Ectothermic animals depend on external heat sources for pursuing their daily activities. However, reaching sufficiently high temperature can be limiting at high altitudes, where nights are cold and seasons short.

Natura Sloveniae, 2004 In summer 2004, Chorthippus apricarius was found on Bloke plateau. This finding confirms the presence of this species in Slovenia, which was previously only documented in two unpublished camp reports.

Chromosomal mapping of rDNAs and H3 histone sequences in the grasshopper
Molecular Cytogenetics, 2011 Background Supernumerary B chromosomes occur in addition to standard karyotype and have been described in about 15% of eukaryotes, being the repetitive DNAs the major component of these chromosomes, including in some cases the presence of multigene ...

A NEW SPECIES OF THE GENUS AEROPEDELLUS FROM HOVSGOL PROVINCE (ORTHOPTERA, ACRIDIDAE: GOMPHOCERINAE)
Proceedings of the Mongolian Academy of Sciences, 2016 We have described a new species of genus Aeropedellus from Mongolia. We collected the specimens from near the Tunamalnuur, Tsagaanuul Sum, Hovsgol Province, Mongolia. The diagnosis and the detail description of the species are provided in this paper.

Genomic evidence of speciation by fusion in a recent radiation of grasshoppers. [PDF]
Evolution, 2022 Abstract Postdivergence gene flow can trigger a number of creative evolutionary outcomes, ranging from the transfer of beneficial alleles across species boundaries (i.e., adaptive introgression) to the formation of new species (i.e., hybrid speciation). Although neutral and adaptive introgression has been broadly documented in nature, hybrid speciation

Replicated Differential Expression Analysis in a Green-Brown Polymorphic Grasshopper Reveals Role of Beta-Carotene-Binding Protein in Body Coloration. [PDF]
Mol EcolABSTRACT Orthoptera provide a well‐documented case of transspecies colour polymorphism, with green and brown morphs coexisting in many species. This colour polymorphism is likely under long‐term balancing selection, but the genetic and molecular mechanisms underlying the variation remain poorly understood.

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection. [PDF]
Insect SciDistinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

Tracking nutrients in space and time: Interactions between grazing lawns and drought drive abundances of tallgrass prairie grasshoppers. [PDF]
Ecol Evol, 2021 Tallgrass prairie grasshoppers live surrounded by their food, but much of the available forage is nutrient poor. We report increases in grasshopper abundance and shifts in composition in response to both grazing lawns, high nutrient patches created by mammalian grazers, and drought, which concentrates nutrients in tallgrass prairie foliage. Abstract We

Body Temperature Differences Between Green And Brown Grasshoppers Do Not Result From Thermal Physiology or Thermal Preferences. [PDF]
Ecol EvolColour morphs could represent different life‐history strategies, maximising their fitness locally in the trait space through trade‐offs between different biological functions. This mechanism could play a role in the maintenance of the green–brown polymorphism in Orthoptera.
