Body size patterns of Pholidoptera frivaldskyi (Orthoptera) in very isolated populations

Effects of Abiotic Factors on the Geographic Distribution of Body Size Variation and Chromosomal Polymorphisms in Two Neotropical Grasshopper Species (Dichroplus: Melanoplinae: Acrididae)

“…Despite their isolation, all three populations did not show consistent differences in body size apart from the intrapopulational ones. This may indicate a similar environmental effect of ambient conditions on the phenotypic plasticity of the populations and a genetic uniformity aided by the small size of the populations and a relatively recent origin before fragmentation [63].…”

“…In a study of species composition and body size of Tettigoniid species in Atlantic coast salt marshes on Spartina alterniflora (Poaceae) communities (latitudinal range, 13.19 • ), Fabriciusová et al [63] showed converse Bergmannian patterns for two species, Orchelimum fidicinium and Conocephalus spartinae. O. fidicinium, the largest species, dominated the tettigoniid community at low latitudes and C. spartinae, the smallest species, at high latitudes.…”

Isolated populations of the bush-cricket Pholidoptera frivaldszkyi (Orthoptera, Tettigoniidae) in Russia suggest a disjunct area of the species distribution

“…Genetic structure (mitochondrial DNA) and variation of morphological traits as individually specific pattern of black spots on the light green shield and head in fragmented and isolated populations of this flightless sedentary insect occurring in central and south-eastern Europe confirm the species’ relict-like character (Fabriciusová et al 2008; Kaňuch et al 2014). Scarce records have determined its main distribution area in the Carpathian Mountains and mountains on the Balkan Peninsula, with an emphasis on the former (e.g.…”

“…are considered as typical habitat for P. frivaldszkyi (e.g. Nagy 2005; Fabriciusová et al 2008; Iorgu et al 2008; Krištín et al 2013); thus, one could have expected that lowland populations in the remote (1300–2400 km) East European Plain should be founded by unintentional vector-born or human-mediated introductions. Similar events have already been confirmed in some Orthoptera species (Wagner 2004; Kaňuch et al 2013).…”

“…Scarce records have determined its main distribution area in the Carpathian Mountains and mountains on the Balkan Peninsula, with an emphasis on the former (e.g. Harz 1969; Nagy 2005; Warchałowska-Śliwa et al 2005; Fabriciusová et al 2008; Iorgu et al 2008; Chobanov and Mihajlova 2010; Krištín et al 2013; Hochkirch et al 2016). Findings further to the north-east, beyond the Carpathian massif, reported from Ukraine and Russia were relatively old, unlocalised or incomplete (e.g.…”
