The Poecilimon bosphoricus species group, representing the most diverse lineage of the bushcricket genus Poecilimon, has been studied in the Basin of Marmara Sea. Two new species, P. warchalowskae sp. n. and P. canakkale sp. n., are described morphologically and acoustically in comparison to their related taxa of the P. bosphoricus species group. S...

Although the high-latitude range margins in Europe and North America are intensively studied, attention is gradually turned towards the taxa/populations inhabiting glacial refugia. Here, we evaluate the genealogical history of the cold-adapted Anatolio-Balkan genus Anterastes especially to test the possible effects of intrarefugial vertical range s...

The Quaternary biogeography of Anatolia has received considerable interest recently. Here, the genealogical history of the Anatolio−Balkan lineage of the Poecilimon luschani species group was evaluated. Using concatenated data from 16S rDNA and cytochromec oxidase subunit I (COI) sequences, the timings of inter- and intraspecies radiations were est...

The Poecilimon luschani species group (Orthoptera, Tettigonioidea, Phaneropterinae), ranging along a narrow line in West Anatolia and the Balkan mountains, has been revised using integrated data from morphology, bioacoustics, and DNA sequences of two matrilineal markers. A taxonomic approach neutral with respect to existing species/subspecies was a...

Active tectonic history of the Eastern Mediterranean, especially around Aegean area, through the Neogene led to interesting radiation patterns of animal lineages, allowing intriguing biogeographical hypotheses to be tested. Descendants of the ancestral stock in the Miocene Aegean Plate presently occur in the Anatolia, Aegean islands and the Balkan...

Cryptic species are black boxes of taxonomy and need to be addressed with an integrative taxonomic approach. Simulium (Diptera: Simuliidae) may contain a substantial amount of cryptic species diversity due to its large cross-continental distribution and habitat-based canalization in taxonomic characters. Except for Simulium sergenti, the following...

High-density genomic data analyzed by accurate statistical methods are of potential to enlighten past breeding practices such as selection by unraveling fixed regions. In this study, four native Turkish sheep breeds (80 samples) were genotyped via 296.097 single nucleotide polymorphisms (SNPs) detected by double-digest restriction site-associated D...

Via long‐term natural and artificial selection pressure, homozygosity may extend across the genome, leaving genomic patterns called selection signatures. This study is the first attempt to assess genome‐wide selection signatures in six native Turkish and two cosmopolitan cattle breeds by 211.119 bi‐allelic SNPs recovered using the double digest res...

This is the first comprehensive study to reveal genetic variation and population structure at genome level in six Anatolian (Anatolian Black, East Anatolian Red, South Anatolian Red, South Anatolian Yellow, Turkish Grey Steppe, and Zavot) and two cosmopolitan (Brown Swiss and Holstein Friesian) cattle breeds reared in Türkiye. Being 20 samples from...

Simple Summary The chukar partridge (Alectoris chukar) is an important bird species with significant economic and ecological value. Every year, thousands of partridges raised in Ministry of Agriculture and Forestry breeding farms are released into nature for hunting purposes. Our investigation of the gene pools of different A. chukar populations us...

Mitochondrial DNA has been the preferential genome biodiversity studies. However, several factors contribute to its inadequacy. Numts constitute one of the main complications that prevent obtaining orthologous mitochondrial sequences. Orthoptera have been a model group in numt studies because of their huge genome size. In this study we aimed to; (i...

Poecilimon Fischer (Orthoptera, Tettigoniidae) consists of about 130 species and a functional taxonomy of the genus re- quires arranging species into phylogenetic groups. However, this is a task that requires detailed empirical testing. This paper documents data on Poecilimon species with an inflated pronotum. The Poecilimon (Poecilimon) inflatus g...

Poecilimon Fischer (Orthoptera, Tettigoniidae) is the most species-rich genus of the respective order and family in Anatolia. However, intrageneric diversity still needs to be documented. Poecilimon zonatus Bolívar is a species with a relatively wide range of distribution in Anatolia compared to other congeners. The present study aims to examine th...

High mountain ranges within and around Anatolia have played an important role in the biogeography of mountainous organisms, which are threatened by climate change. Using the Psorodonotus caucasicus species group (PCG), whose range is the Caucasus, Anatolia and the Balkans, as a model group, this study aims to determine the importance of Anatolian m...

Due to active tectonic evolution of the Aegean Area during Miocene and Pleistocene, the Balkans and Anatolia have repeatedly connected and disconnected causing isolation and secondary contact of populations along the present Dardanelles – Sea of Marmara – Bosphorus waterway. This has led to an outstandingly rich fauna and a reticulate biogeography...

The peripatric or budding species model has remained theoretical until recently. The habitat preference and range pattern of the mountainous Psorodonotus venosus species group, distributed in Anatolia and Caucasus, offered potential to test the predictions of the model. The study aimed to confirm the parameters and to provide evidence for peripatri...

A review of the Balkan representatives of the genus Psorodonotus was made with the aim of revealing the relationships between taxa and their systematic arrangement. For this purpose we used morphological (qualitative and quantitavive), acoustic (amplitude- temporal song parameters) and molecular (mtDNA COI gene sequence) data. The analyses and comp...

The Anatolio-Caucasio-Balkan genus Psorodonotus (Orthoptera, Tettigoniidae) presently includes 13 species belonging to three species groups. In the present study we review the Specularis group and describe two new species-P. rize Kaya & Ciplak sp. n. and P. giresun Kaya & Ciplak sp. n.. Data obtained of 21 different populations from the North-easte...

Psorodonotus (Orthoptera, Tettigoniidae) includes 11 species distributed in Caucasus, Anatolia and Balkans. Although its present taxonomy is problematic, mainly three species groups can be distinguished; (i) The Specularis Group, (ii) The Caucasicus Group and (iii) The Venosus Group. Our recent studies on the genus have revealed presence of two new...

Although changes in biodiversity and in ecosystems are surely caused by a range of interacting drivers, such as natural or human-induced factors, one of the important drivers having major impacts on climate and biodiversity and leading to range changes and fragmentation is global warming. Defining past range changes/fragmentations during interglaci...

The new species Anterastes davrazensis sp. n. (Orthoptera, Tettigoniidae) is described from south-eastern Turkey. Description, diagnosis and relationships of the new species were studied utilizing morphology, male calling songs and 16S rDNA sequence data from all species in the genus. Morphology and song syllable structure indicate A. davrazensis s...

More than 20 species were reported under the circum Black Sea lineage Poecilimon bosphoricus group (Orthoptera, Tet-tigonioidea, Phaneropterinae). The taxonomy of the group has for a long time been controversial; once these species were transferred to Eupoecilimon and many new species have been described since the revision by Ramme (1933) or synony...

Among the Anatolian Tettigoniinae (Orthoptera, Tettigoniidae) the genera Anterastes, Koroglus, Sureyaella and Rhaco-cleis are distinguishable from the others by presence of one pair of spurs on the apico-ventral end of hind tibiae. The last two can be easily distinguished from the others by several distinct features, but the separation of the first...

Ten species of the genus Anterastes Brunner von Wattenwyl (Orthoptera, Tettigoniidae) show insular distribution in mountain meadows of Anatolia and the Balkans. Current understanding of the taxonomy and species relationships within the genus is based on morphological characters. However, the extent to which morphological characters are phylogenetic...

We examined size clines for various external body structures in two grasshopper species (Chorthippus vagans and Oedipoda miniata) and one katydid species (Poecilimon birandi), along an altitudinal gradient ranging from sea level to 1,980 m in southwest Anatolia (Turkey). In O. miniata and P. birandi all measured structures (body, tegmina, pronotum,...
