One of the work on this subieét come from John and Hewitt (1966). According to them, the karyotypic stability assumed for the species of the family Acrididae in studies made on chromosome number and structure is not true when the amount of DNA of spermatid nuclei are t-aken on accoun£.

The DNA content per nucleus in arbitrary units wa; determined according to Frazer and Davidson (1953). All the extintion~-values were taken in a Zeiss citophotometer at the wavelength of 560 nm fo`i each of 10 nuclei from 3 individuals in each specie. The extintion value for each nucleus was the mean of three values obtained at three different plugs. The values of the DNA content obtained for each species were arranged in histograms (Fig.1).

AL. FEE+REIRAL, DNA contents in Acrididae 39 DISCUSSION The results of DNA content obtained cytophotometrica]ly in species of the family Acrididae with similar karyotypes show that chromosomal rearrangement not detetable at chromosomal level ocurred in these species during the philogenetic process, since significant differences in DNA content was observed between them. Similar results were obtained by John and Hewitt (ig6ó).iThe nature of these chromosomal rearrangement is unknown at the moment, but the most probable hypotesis is concerned with the occurrence of duplication or dificiency (Rees and Jones,1967). In spite of the great chromosomal rearrangement that has modified its karyotype (Ferrcira, 1974, 1975) A/cG£¢s gy¢w./í.s has a DNA content not significant different from Rbcz77c77?¢£occrz/s co7¢spcr.s#s that has a karyotype without any aparent change in its organization® The similarity of DNA content observed in 077?c#ecb¢ scrt;z.//cÍ. in Xy/cc# sP iand in Rbcz77277?¢£occ7"s co7?s,')crs#s seems to shows a close phylogenetic relationship between the families Acrididae and Omexechidae thought more species should be studied. This point of view is in according with the cytological data. Mesa (1963, 1964) has claimed that the basic karyotype of the family Omexechidae is secondarely derived from the 23 acrocentric chromosomes normally found in the species of the family Acrididae by a pericentric inversion in its longes+¿ autosomes. Cepb¢/ococ77?cz borc//z., the single species of the family Proscopiidae here studied, has approximately half of the averaged DNA content found in the remaining five species, which belongs to the families Ommexechidae (1 sp), Acrididae (3 sp) and Rommaleidae (1 sp). Thought fragmentaries, sinc€ more species shoul be taken on account in future studies our observations seems to show no close relationships between Proscopiidae and the above mentioned families. Also from the citological point of view the species óf the family ProscQpiidae depart from the classical 2n= 23 -24 of the true grasshoppers. In fact, according to several papers published (Piza,1943,1945; De Castro,1946; Dasgupta, 1960; Santiago, 1968; Mesa, 1973; Ferreira, 1974), de most common number in Proscopiidae is 2n = 19-20, with all the chromos()mes acrocent..'ic. In a few species (Mesa, 1973 and Ferreira, 1974) this karyotype has been modified throught several structural rearragements. The above mentioned observations agree with the recent point of view of Kevan (1966') and Blackith and Blackith (19661967 a and 1967 b), that based on morphologiéal considerations removed Proscopiidae from Acridoidea. The authors placed it on Eumastacoidea and recently Descamps (1973) studyng the phallic complex of species belonring to 9 genus from the 14 álready known creat.ed the Super-family Proscopoidea with a single family Proscopiidae that possess all the species described.

  • Fossil Perspectives on the Evolution of Insect Diversity
    FOSSIL PERSPECTIVES ON THE EVOLUTION OF INSECT DIVERSITY Thesis submitted by David B Nicholson For examination for the degree of PhD University of York Department of Biology November 2012 1 Abstract A key contribution of palaeontology has been the elucidation of macroevolutionary patterns and processes through deep time, with fossils providing the only direct temporal evidence of how life has responded to a variety of forces. Thus, palaeontology may provide important information on the extinction crisis facing the biosphere today, and its likely consequences. Hexapods (insects and close relatives) comprise over 50% of described species. Explaining why this group dominates terrestrial biodiversity is a major challenge. In this thesis, I present a new dataset of hexapod fossil family ranges compiled from published literature up to the end of 2009. Between four and five hundred families have been added to the hexapod fossil record since previous compilations were published in the early 1990s. Despite this, the broad pattern of described richness through time depicted remains similar, with described richness increasing steadily through geological history and a shift in dominant taxa after the Palaeozoic. However, after detrending, described richness is not well correlated with the earlier datasets, indicating significant changes in shorter term patterns. Corrections for rock record and sampling effort change some of the patterns seen. The time series produced identify several features of the fossil record of insects as likely artefacts, such as high Carboniferous richness, a Cretaceous plateau, and a late Eocene jump in richness. Other features seem more robust, such as a Permian rise and peak, high turnover at the end of the Permian, and a late-Jurassic rise.

  • U1 Sndna Clusters in Grasshoppers: Chromosomal Dynamics and Genomic Organization
    Heredity (2015) 114, 207–219 & 2015 Macmillan Publishers Limited All rights reserved 0018-067X/15 www.nature.com/hdy ORIGINAL ARTICLE U1 snDNA clusters in grasshoppers: chromosomal dynamics and genomic organization A Anjos1, FJ Ruiz-Ruano2, JPM Camacho2, V Loreto3, J Cabrero2, MJ de Souza3 and DC Cabral-de-Mello1 The spliceosome, constituted by a protein set associated with small nuclear RNA (snRNA), is responsible for mRNA maturation through intron removal. Among snRNA genes, U1 is generally a conserved repetitive sequence. To unveil the chromosomal/ genomic dynamics of this multigene family in grasshoppers, we mapped U1 genes by fluorescence in situ hybridization in 70 species belonging to the families Proscopiidae, Pyrgomorphidae, Ommexechidae, Romaleidae and Acrididae. Evident clusters were observed in all species, indicating that, at least, some U1 repeats are tandemly arrayed. High conservation was observed in the first four families, with most species carrying a single U1 cluster, frequently located in the third or fourth longest autosome. By contrast, extensive variation was observed among Acrididae, from a single chromosome pair carrying U1 to all chromosome pairs carrying it, with occasional occurrence of two or more clusters in the same chromosome. DNA sequence analysis in Eyprepocnemis plorans (species carrying U1 clusters on seven different chromosome pairs) and Locusta migratoria (carrying U1 in a single chromosome pair) supported the coexistence of functional and pseudogenic lineages. One of these pseudogenic lineages was truncated in the same nucleotide position in both species, suggesting that it was present in a common ancestor to both species. At least in E. plorans, this U1 snDNA pseudogenic lineage was associated with 5S rDNA and short interspersed elements (SINE)-like mobile elements.

    C 1996 The Japan Mendel Society Cytologia 61: 169-178, 1996 Cytotaxonomic Characterization of the Genera Scleratoscopia and Tetanorhynchus (Orthoptera-Proscopiidae) R. C. Mour1 M. J. Souza1 and T. Tashiro2 1 Departamento de Genetica (CCB), 2Departamento de Educacao Fisica (CCS), Universidade Federal de Pernambuco, Recife-PE, 50732-970 Brazil Accepted March 13, 1996 Proscopiidae is an endemic family in South America and is considered to descend from acridomorphs or pre-acridomorphs inhabiting the South American region of Gondwana (Carbonell 1977). From a taxonomic viewpoint, proscopiids are quite distinct from other acridomorph families. However, some similarities in external morphology and phallic complex are detected when this family is compared to Eumastacidae, especially the Australian subfamily Morabinae. This evidence suggests that these families are phylogenetically related (Dirsh 1961, Randell 1963, Blackith and Blackith 1966). According to Amedegnato (1993), the similarities between morabines and proscopiids indicate that these groups are members of the same phyletic unit although descending from different eumastacids. Analysis of the structure of male genitals and of other traits indicates that proscopiids are derived from an ancestral group of Eumasta- cidae (Cryptophalli), the Teicophrynae subfamily of North America. The members of this subfamily present a structure of the phallic complex similar to that of Asian Gomphomastaci- nae, which probably gave origin to morabids. On the basis of a study of male genitals, Jago (1989) extensively reviewed the taxonomy of the family Proscopiidae. In this analysis, he reviewed and defined 21 genera, seven of them new (Astromascopia , Bolichohynchus , Carphoproscopia , Microcoema , Pseudastroma , Scopaeoscle- ratoscopia and Scleratoscopia). The description of the genus Scleratoscopia (Jago 1989) was based on the species type Cephalocoema protopeirae Amedegnato 1985 and comprises three species: S.

    www.nature.com/scientificreports OPEN Large‑scale comparative analysis of cytogenetic markers across Lepidoptera Irena Provazníková 1,2,3, Martina Hejníčková 1,2, Sander Visser 1,2,4, Martina Dalíková 1,2, Leonela Z. Carabajal Paladino 5, Magda Zrzavá 1,2, Anna Voleníková 1,2, František Marec 2 & Petr Nguyen 1,2* Fluorescence in situ hybridization (FISH) allows identifcation of particular chromosomes and their rearrangements. Using FISH with signal enhancement via antibody amplifcation and enzymatically catalysed reporter deposition, we evaluated applicability of universal cytogenetic markers, namely 18S and 5S rDNA genes, U1 and U2 snRNA genes, and histone H3 genes, in the study of the karyotype evolution in moths and butterfies. Major rDNA underwent rather erratic evolution, which does not always refect chromosomal changes. In contrast, the hybridization pattern of histone H3 genes was well conserved, refecting the stable organisation of lepidopteran genomes. Unlike 5S rDNA and U1 and U2 snRNA genes which we failed to detect, except for 5S rDNA in a few representatives of early diverging lepidopteran lineages. To explain the negative FISH results, we used quantitative PCR and Southern hybridization to estimate the copy number and organization of the studied genes in selected species. The results suggested that their detection was hampered by long spacers between the genes and/or their scattered distribution. Our results question homology of 5S rDNA and U1 and U2 snRNA loci in comparative studies. We recommend the use of histone H3 in studies of karyotype evolution. Cytogenetic studies aim at characterization of genome organization and its changes. Previously indispensable for the identifcation of genes of interest, cytogenetics may seem to struggle in the post-genomic era as it lags behind the resolution of molecular biology and genomics.
