AbstractIllustrated identification keys are given for the superfamilies/families of insect parasitoids and the subfamilies, genera, and species of Braconidae reared from species of Choristoneura Lederer in the Nearctic Region. Goniozus floridanus (Ashmead) (Chrysidoidea: Bethylidae) represents the third superfamily of Hymenoptera, and Colpoclypeus florus (Walker) (Hymenoptera: Eulophidae) is added to the list of Chalcidoidea recorded from Choristoneura. Fifty species of Braconidae in 18 genera and 9 subfamilies are recorded parasitizing 11 Choristoneura species; almost half belong to the Microgastrinae. Eight braconids (16%) were found for the first time as parasitoids of Choristoneura. The first host record is given for Oncophanes californicus (Ashmead) (Hormiinae). Known insect parasitoids of Choristoneura spp. in the Nearctic Region include 230 species in 106 genera, about 75% of which attack only 1 or 2 Choristoneura species each. An additional 36 species are considered incorrectly associated with Choristoneura, an error rate of 14%. The Banchinae (Ichneumonidae, especially Glypta Gravenhorst), Pimplinae (Ichneumonidae), and Microgastrinae (Braconidae) made up the greatest proportion of parasitoids. No parasitoids have yet been recorded from five Nearctic Choristoneura species.

Summary Population of Iranolacerta brandtii lizard including 56 (21♀, 34♂, 1 juvenile) samples were examined for helminths. 17 of them were found to harbour one or more helminth parasites, while 39 didn’t harbor any. Two helminth species were determined. These belong to Phylum: Nematoda, Spauligodon aloisei Casanova, Milazzo, Ribas & Cagnin, 2003 and Skrjabinodon medinae. García-Calvente, 1948. This study represents new host and locality records in both host lizard and the helminth species. Sp. aloisei is recorded for the first time; Sk. medinae is the third report from Turkey nevertheless Sk. medinae is a new host record for I. brandtii.

Vertebrate trace fossils are reported for the first time from red beds near the top of megacyclic sequence II at Prim Point in southwestern Prince Edward Island. They occur as casts of tetrapod trackways. The ichnocoenose also includes a rich invertebrate ichnofauna. The trackmakers thrived in an area of sparse vegetation and occupied out-of-channel river sediments, most likely crevasse-splay deposits.Amphisauropus latus, represented by three trackways, has been previously reported from Germany, Poland, and Czechoslovakia. It is here interpreted as the track of a cotylosaur. It occurs together with the track of Gilmoreichnus kablikae, which is either a captorhinomorph or possibly a juvenile pelycosaur. These facilitate the assignment of a late Early Permian (late Autunian) age to the strata. The third set of footprints, those of a small herbivorous pelycosaur, compare most closely with Ichniotherium willsi, known hitherto from the Keele beds (latest Stephanian) of the English Midlands.This ichnocoenose occurs in a plate-tectonically rafted segment of crust stratigraphically equivalent to the same association of ichnofauna in the English Midlands and central Europe. The community occupied piedmont-valley-flat red beds within the molasse facies of Variscan uplands.

AbstractThe 11 genera of Nearctic Braconini are keyed: two of them, Myosoma Brullé with a wide pantropical range and Alienoclypeus Shenefelt, new genus, are found chiefly in the Chihuahuan desert and shrub fauna of northern Mexico and the southwestern U.S.A. and are recorded as Nearctic for the first time. Four new species are described in Myosoma: eumystax, impexum, longius, and durango. R. D. Shenefelt describes a new genus and species, Alienoclypeus insolitus. The genus Atanycolimorpha Viereck, 1913 is synonymized with Ipobracon Thomson, 1892. The genus Coeloides is revised for the Nearctic Region; 12 species are described and illustrated. Five of these are new: mexicanus, durangensis, sympitys, tsugatorus, and sonora. One species, C. rossicus (Kokujev), is Holarctic, a new subspecies, betulae, is described from Canada. The following are new synonyms: C. rufovariegatus (Provancher) = (dendroctoni Cushman), C. vancouverensis (Dalla Torre) = (brunneri Viereck), C. crocator (Kirby) = (promontorii Dalla Torre).

AbstractThe Nearctic Idiocerini exclusive of the fauna of the Sonoran subregion are reviewed. The 68 recognized species are assigned to three genera: Idiocerus Lewis, Rhytidodus Fieber, and Balcanocerus Maldonado-Capriles. Three subgenera of Idiocerus are recognized, including I. (Liocratus) Dub. and I. (Populicerus) Dlab. (n. stat). Sahlbergotettix Zvk., 1953, Viridicerus Dlab., 1974, Tremulicerus Dlab., 1974, and Acericerus Dlab., 1974 are synonymized with Idiocerus Lewis, 1834.Sixteen new species of Idiocerus are described: aureus, carolina, cedrus, freytagi, gillettei, immaculatus, inebrius, iodes, lucidae, midas, pericallis, taiga, unicolor, vanduzeei, venosus, and xanthiops. I. varions n. n. is created for varias DeLong & Hershberger, 1947 (nec Germar, 1818). I. lunaris Ball (n. stat.), I. obsoletus (Wlk.) (n. stat.), and I. raphus Freytag (n. stat.) are recognized as valid species for the first time. Twelve other species are removed from synonymy. I. verrucosus Ball is placed as a subspecies of I. musteus Ball (n. stat.). Five new synonymies are created: alnirubratus Bliven, 1955 = I. couleanus Ball & Pkr., 1946; nigrens DeL. & Cld., 1937 = I. distinctus Gill & Bak., 1895; duzeei Prov., 1890 and vagus Ball, 1902 = obsoletus Walker, 1851; and apertus DeL & Hbr., 1947 = I. verticis (Say), 1831.Additional characters of the male antennae, male abdominal apodemes, and female ovipositor are described and illustrated. The phylogeny and hosts of the members of Idiocerus are discussed. Keys are provided to the genera of the Nearctic Idiocerini, and to the species of Idiocerus of the Nearctic region, exclusive of the Sonoran subregion, for both sexes.

AbstractA new technology for obtainment of amorphous single-component metals is presented.For the first time the reduction of molybdenum oxide with formation of its amorphous phase is realized in conditions of a given quantum-chemical technology by means of vibrationally excited to the third quantum level hydrogen molecules with 1.5 ± 0.2 eV energy. The evidences of formation of this nonequilibrium amorphous phase are presented along with certain physicochemical properties of the obtained amorphous molybdenum.A model is proposed for the origin of amorphous phase under the influence of nonequilibrium quantum-chemical technology.

"In the article under consideration are the ways of symphony genre transformation in the early works of Valentin Silvestrov (Ukraine). For the first time, the First, Second, Third, and Fourth symphonies by the genius composers of the 20th century are analyzed as a certain stylistic system. These compositions are endowed with the features of avant-garde poetics, and as a subject of musicological reflection, they are associated with a rethinking of the semantic paradigm of the genre. V. Silvestrov's early symphonies stand out from the classical practice of European symphonies. Scientific awareness of their phenomenal nature necessitated a methodological choice aimed at the most accurate identification of the philosophical concept of the new sound universum of V. Silvestrov's music. Deep correlation of the image of a human being as a factor of the symphony poetics (the influence of philosophical concepts of human ontology in the 20th century with the transformation of the genre canon) is considered. This refers to the nonmusical dimension of the genre semantics. The study of V. Silvestrov's early symphonies reveal a new philosophy of music through gradual movement – modulation: from the neo-baroque First Symphony and ""cosmic pastorals"" Musica Mundana of the Second Symphony through the history anthropologisation in the Third Symphony ""Eschatology"" to the monodrama Musica Humana in the Fourth Symphony. The dichotomy of Musica Mundana – Musica Humana is not accidental: in V. Silvestrov's creative method, remains relevant, which is confirmed by the dramaturgy of his latest work – the Ninth symphony (2019). Keywords: V. Silvestrov's early symphonies, evolution of style, worldview, Musica Mundana, monodrama. "

The Relationship

Abstract Since the third wave of democracy, term limits have become a popular fixture of most constitutions intended to constrain the executive. Yet, recent constitutional reforms around the world show that presidents seeking re-election sometimes overturn the entire constitutional order to extend their power. What is the impact of these constitutional manipulations on the longevity of the executive in office? Using survival analysis of all political leaders and national constitutions from 1875 to 2015, this article demonstrates, for the first time, that when ‘authoritarian-aspiring’ presidents remove constitutional term limits, they increase their stay in office by more than 40%. Our findings contrast with a widely held position in the comparative authoritarian literature suggesting that dictators survive longer under institutional constraints. On the contrary, we argue that by removing constitutional barriers, rulers consolidate more power at the expense of their most ambitious allies and can stay in power longer.
