Bacterial symbionts of the leafhopper Evacanthus interruptus (Linnaeus, 1758) (Insecta, Hemiptera, Cicadellidae: Evacanthinae)
Plant sap-feeding hemipterans harbor obligate symbiotic microorganisms which are responsible for the synthesis of amino acids missing in their diet. In this study, we characterized the obligate…

Review of the Balkan Isophya (Orthoptera: Phaneropteridae) with particular emphasis on the Isophya modesta group and remarks on the systematics of the genus based on morphological and acoustic data.
A critical review of the taxonomy and systematics of the genus Isophya from the Balkan Peninsula, together with a revision of the I. modesta group, including its representatives outside the Balkans,…

The macroecology of the COVID-19 pandemic in the Anthropocene
TLDR
It is demonstrated that the characteristics of the human population and high mobility, but not population density, may help explain the global spread of the coronavirus, and suggests that COVID-19 may be a new civilisation disease affecting rich economies.

The Anatolio‐Balkan phylogeographic fault: a snapshot from the genus Isophya (Orthoptera, Tettigoniidae)
TLDR
Most of the studied phenetic species are monophyletic, but some earlier suggested morpho‐species groups are not, and three main episodes dominate the evolutionary history of Isophya, which well correlate with episodes of existing terrestrial connections between Anatolia and the Balkans.

Phylogenetic relationship of Japanese Podismini species (Orthoptera: Acrididae: Melanoplinae) inferred from a partial sequence of cytochrome c oxidase subunit I gene
TLDR
Results did not correspond with the classification on the basis of morphological similarity for the status of Tonkinacridina, and this incongruence might have resulted from historical migratory events between continent and ancient islands and subsequent convergent/parallel evolution in morphology.

Comparative analysis of the location of rDNA in the Palaearctic bushcricket genus Isophya (Orthoptera: Tettigoniidae: Phaneropterinae)
TLDR
The cytogenetic mapping revealed great variability among Isophya species in the chromosomal location of major r DNA clusters, suggesting that the observed variation in the number of rDNA clusters can be an important species-group specific phylogenetic marker.

A comparative study of genome organization and inferences for the systematics of two large bushcricket genera of the tribe Barbitistini (Orthoptera: Tettigoniidae: Phaneropterinae)
TLDR
It was concluded that the physical mapping of rDNA sequences and heterochromatin may be used as an additional marker for understanding interspecific relationships in these groups and their routes of speciation.

Taxonomy of the genus Isophya (Orthoptera, Phaneropteridae, Barbitistinae): comparison of karyological and morphological data.
TLDR
Cytogenetic analysis revealed some changes reflecting the level of genomic organization of the genus Isophya, and the results suggest some association of related taxa from biogeographic regions.

Review of the Plangia graminea (Serville) complex and the description of new Plangia species from East Africa (Orthoptera: Phaneropteridae, Phaneropterinae) with data on habitat, bioacoustics, and…
TLDR
Niche specialization and the male calling song are discussed as drivers for speciation in fully alate and thus mobile taxa in Plangia suggesting different mechanisms leading to these differences.

Cytogenetic variability among Bradyporinae species (Orthoptera: Tettigoniidae)
TLDR
Chromosomes of six European species of Orthoptera belonging to the tribes Ephippigerini and Bradyporini were analyzed using C-banding, Ag-NOR, DAPI (AT-rich)/CMA3 (GC-rich) staining and fluorescence in situ hybridization (FISH) to better understand chromosomal organization and evolutionary relationships between genera and subgenera within and across both tribes.
