Animal genomes vary widely in size, and much of their architecture content remains poorly understood. Even among related groups, such as orders insects, may size by magnitude–for reasons unknown. The largest known insect were repeatedly found Orthoptera, e.g., Podisma pedestris (1C = 16.93 pg), Stethophyma grossum 18.48 pg) Bryodemella holdereri 18.64 pg). While all these species belong to the suborder Caelifera, ensiferan Deracantha onos 19.60 was recently have genome. Here, we present new...
Lissencephaly is a neuronal migration disorder leading to absent or reduced gyration and broadened but poorly organized cortex. The most common form of lissencephaly isolated, referred as classic type 1 lissencephaly. Type mostly associated with heterozygous deletion the entire LIS1 gene, whereas intragenic mutations hemizygous DCX in males are less common.Eighteen unrelated patients were clinically genetically assessed. In addition, subcortical band heterotopia (n = 1) cerebellar hypoplasia...
Mitochondrial gene order has contributed to the elucidation of evolutionary relationships in several animal groups. It generally found its application as a phylogenetic marker for deep nodes. Yet, Orthoptera limited research been performed on order, although group represents one oldest insect orders. We comprehensive study mitochondrial genome rearrangements (MTRs) within context mitogenomic sequence-based phylogeny. used 280 published mitogenome sequences from 256 species, including three...
Mongolia, a country in central Asia, with its vast grassland areas represents hotspot for Orthoptera diversity, especially the Acrididae. For 128 Acrididae species have been documented so far, of which 41 belong to subfamily Oedipodinae (band-winged grasshoppers). Yet, few studies concerning distribution and diversity conducted this country. Molecular genetic data is almost completely absent, despite value identification discovery. Even, simplest most used data, DNA barcodes, far not...
Abstract Orthoptera have some of the largest genomes all insects. At same time, architecture their remains poorly understood. Comparative cytological data across a wide range taxa, even for basic parameters such as chromosome number, may provide important insights into evolution these and help answer question why species attained large genome sizes. We collected compiled more than 1,000 records numbers 339 genera (13.8% 2,452 known genera) 769 (6.2% 12,250 species) Caelifera, suborder that...
Habitat destruction and fragmentation are among the major current threats to global biodiversity. Fragmentation may also affect species with good dispersal abilities. We study heath bushcricket Gampsocleis glabra, a specialist of steppe-like habitats across Europe that highly fragmented, investigating if these isolated populations can be distinguished using population genomics there any traces admixture or them. try answer questions genome-wide SNP data generated ddRAD sequencing. calculated...
DNA barcoding represents an objective tool for fast species identification, especially taxa which morphological identification is difficult. One current limitation of the lack reference sequences many groups. While European and North American countries have started their own initiatives to generate complete local inventories databases, such efforts are sparse African, Asian South countries, despite high biodiversity comparably poorly explored faunas. Therefore, it important start in...
Abstract The genus Thalpomena Saussure comprises nine species and four subspecies is largely endemic to the Atlas Mountains (North Africa). Here, we used an evolutionary taxonomic approach differentiate of reconstruct their biogeographic history. Phylogenetic tree reconstruction based on five molecular markers revealed distinct clades within . These are not fully in line with current taxonomy but rather seem represent lineages defined by distribution hind wing banding patterns. All...
Abstract Isophya modestior (Orthoptera: Tettigoniidae) is a species distributed in central and south-eastern Europe, where its distribution largely separated by two large rivers (Sava Danube). Since previous studies on the song morphology of stridulatory file across complete geographic range showed that into main groups, we decided to use phylogenetic karyological analyses order evaluate status previously analysed populations. Phylogenetic existence major clades within I. with very high...
Zoological collections remain the main archive of animal life on earth, especially in times mass extinctions. The most important animals these are type specimens, which represent original reference for a species. While full digitization museum currently remains utopic, lists types an essential resource researchers to perform taxonomic revisions. Here, we provide updated catalogue short-horned grasshoppers (Caelifera) housed Museum Hamburg (ZMH), now part Center Natural History (CeNak). This...
The yellow-legged, or Asian hornet, Vespa velutina , has invaded large parts of South-Western Europe and now starts spreading further north. Recently, it been reported from Hamburg, Northern Germany. Yet, the origin this new invasion is not clear as founders may have come either Southern Asia. We here use COI sequences to test these alternatives find that specimens Hamburg share same haplotype with all European samples. This suggests species transported long distance other Germany shows its...
Types represent the ultimate taxonomic information of a species and hence most important specimens in museums. The entomological collections Zoological Museum Hamburg (now part Centrum für Naturkunde) hold several thousand primary types insects. However, despite their importance currently no type database exists catalogues have not been updated since almost 50 years are only available German. Following publication our catalogue Caelifera types, we here present an for Ensifera held collection...
Abstract The evolutionary history and biogeography of species is strongly influenced by climatic conditions geomorphology. Most thermophilic organisms in Europe have survived colder periods Mediterranean refugia, which can be inferred from their genetic structure. band-winged grasshopper genus Oedipoda occurs with nine the Mediterranean. We phylogeny western Palaearctic using gene sequences (two mitochondrial one nuclear) a comprehensive sample most species. Our results show that...
Abstract Sphingonotus (Sphingonotus) rubescens (Walker, 1870) occurs from the Atlantic Islands to central and southern Asia, but its ecological preferences potential drivers that shaped currently extensive distribution remain unknown. We review known occurrence data for S. reconstruct current palaeoclimatic niche (Last Glacial Maximum mid-Holocene) using species modelling (SDM). examine how climatic suitability might have created past migratory pathways shaping distribution. Moreover, we...
During recent decades, increasing research of the taxonomy genus Isophya resulted in taxonomic descriptions several new species. The delimitation these species is mainly based on oscillographic song analysis male combination with morphological characters, such as shape cerci, tegmina and ovipositor. In present paper, we used an integrative approach order to resolve status four recently described taxa from Serbia. Based our molecular bioacoustic analyses, all analyzed belong a single species:...
A type catalogue of Oedipodinae in the collection Naturalis Biodiversity Center is presented altogether 82 specimens including 13 primary types and 5 junior synonyms: holotypes (4 species), neotype (1 lectotypes (2 species, 1 subspecies), syntypes (5 species). Furthermore 50 additional secondary were recorded. Here, we present full material a locality map all species pictures 15 species.
