European Red List of Grasshoppers, Crickets and Bush-crickets
The European Red List of Grasshoppers, Crickets and Bush- Crickets, which provides the first ever comprehensive assessment of the extinction risk of all Orthoptera species native to Europe, highlights that 25.7% of OrthopterA species are threatened with extinction in Europe.
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 Anatolio‐Balkan phylogeographic fault: a snapshot from the genus Isophya (Orthoptera, Tettigoniidae)
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.
Orthoptera and Mantodea in the collection of the Macedonian Museum of Natural History (Skopje) with an annotated check-list of the groups in Macedonia
The updated check list of the orthoptera fauna of Macedonia comprises four species of Mantodea, 167 Orthoptera taxa and two additional subspecies, and it is revealed that two OrthopterA species must be eliminated from the list ofThe Serbian fauna.
DIET AND FORAGING HABITATS OF NON-BREEDING WHITE STORKS (CICONIA CICONIA) IN BULGARIA
The roosting of non-breeding White Storks appeared when their preferred feeding habitats were ploughed up in the following years, and the number of innutritious materials in the pellets rose when the White Stork hunted on nippy and agile grasshoppers and decreased when the main pray was slower beetles taken from the ground.
Separation of Isomeric Triacylglycerols by Silver Ion Thin-Layer Chromatography
Abstract A procedure for the separation of positionally isomeric triacylglycerols by silver ion thin-layer chromatography at ambient temperature is described. The low silver ion content in the silica…
Comparative analysis of the location of rDNA in the Palaearctic bushcricket genus Isophya (Orthoptera: Tettigoniidae: Phaneropterinae)

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)

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.
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.
Cytogenetic variability among Bradyporinae species (Orthoptera: Tettigoniidae)
- E. Warchałowska-Śliwa, B. Grzywacz, A. Maryańska-Nadachowska, T. Karamysheva, D. Chobanov, K. Heller
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.
