Plastid behavior in reciprocally different crosses between two races of Medicago truncatula Gaertn.
(1962)
During my mork on the inheritance of symmetry characters in Medicago (1956), chance played into my hands a case of fairIy pronounced reciprocal differentes in the behavior of plastids in a cross between two local races of Medicago truncatula GAERTN. which so far I know are not given even varietal rank. The facility in producing the hybrids encouraged me to investigate the material, and the results are reported in this paper.
Introductory chapters on the geography, vegetation and history of botanical ex loration are followed by a catalogue of 331 species of wild vascular plants, 90% of which represent first records for the island. Synonymy, references, localities and ecological data are given for each species in a condensed form. The taxonomy, nomenclature and distribution of some taxa are discussed; in one case (Silene cythnia) a drawing and a distribution map are supplied. Nomenclatural novelties are validated in the genera Centaurea, Matricana, Melica (by W. Hempel) and Trifolium. A phytogeographical and ecological analysis of the flora demonstrates its striking banality and the unexpectedly high proportion of anthropophytes. No pliytogeographical link with tlie other E. Aegean Isiands and Anatolia exists, but there are some affinities with the Cyclades. The observations are consistent with the hypotliesis of a long insular isolation leading to a strong depletion or even destruction of the original flora, which has been replaced by long-distance dispersed and anthropophytic elements.
A world revision of the four entedonine (Hymenoptera: Eulophidae: Entedoninae) genera of larval parasitoids of thrips (Thysanoptera) is presented: Ceranisus Walker, 1841, Entedonomphale Girault, 1915 stat. rev. (reinstated as a valid taxon from previous synonymy under Ceranisus, with type species E. margiscutum Girault, 1915 stat. rev.), Goetheana Girault, 1920, and Thripobius Ferrière, 1938. The following new generic synonymies are proposed: Cryptomphale Girault, 1917, Entedonastichus Girault, 1920, Pirenoidea Girault, 1922, and Thripoctenoides Erdös, 1954 under Entedonomphale. The proposed new combinations are as follows: Entedonomphale bicolorata (Ishii, 1933), E. nubilipennis (Williams, 1916), and Thripobius javae (Girault, 1917) from Ceranisus; Entedonomphale carbonaria (Erdös, 1954), E. dei (Girault, 1922), E. kaulbarsi (Yoshimoto, 1981), and E. mira (Girault, 1920) from Entedonastichus. New synonymies are proposed for the following species: Ceranisus vinctus (Gahan, 1932) under Ceranisus menes (Walker, 1839), Diglyphus aculeo Walker, 1848 under Ceranisus pacuvius (Walker, 1838); Ceranisus maculatus (Waterston, 1930) and Thripobius semiluteus Boucek, 1976 under Thripobius javae (Girault, 1917); Entedonastichus albicoxis (Szelényi, 1982) under Entedonomphale carbonaria (Erdös, 1954), and Entedonastichus gaussi (Ferrière, 1958) under Entedonomphale bicolorata (Ishii, 1933). Eleven new species are described: Ceranisus barsoomensis and C. votetoda (Australia), C. udnamtak (Nepal); Entedonomphale boccaccioi (USA), E. esenini (Madagascar), E. lermontovi (South Africa), E. quasimodo and E. zakavyka (Australia); Goetheana pushkini (Japan and Republic of Korea) and G. rabelaisi (Australia); and Thripobius melikai (China). Three species are excluded from Ceranisus: C. ancylae (Girault, 1917) (mistakenly listed in Ceranisus) as well as C. nigricornis Motschulsky, 1863 and C. semitestaceus Motschulsky, 1863, both taxa incertae sedis. New data are provided on the distribution and host associations of many of the species included in this review.
In dieser Arbeit werden vorwiegend taxonomische und nomenklatorische Angaben zu Cryptini und in einem Fall auch zu Phygadeuontini gemacht. Aus der Westpaläarktis sind derzeit etwa 35 Gattungen von Cryptini bekannt. Einige davon wurden in den letzten Jahrzehnten bereits revidiert (z.B. HORSTMANN 1984, 1987, 1990a, VAN ROSSEM 1966, 1969a, 1969b, 1971, SCHWARZ 1988, 1989, 1990a, 1990b, 1997). Inzwischen konnte weiteres Material untersucht werden, wodurch in einigen Fällen neue Erkenntnisse gewonnen werden konnten. In dieser Arbeit werden vor allem Ergänzungen von Revisionen westpaläarktischer Cryptini gemacht. In einigen Fällen erstrecken sich die Angaben auch auf andere Gebiete (Ostpaläarktis, Orientalis, Äthiopis), Zusätzlich werden Ergebnisse von Typenuntersuchungen angeführt. Bei den untersuchten Typen werden wahlweise die genauen Angaben auf den Etiketten wiedergegeben oder, wenn diese in anderen neueren Publikationen erwähnt sind, weggelassen. Nach den Angaben zum Typus bzw. zu den Funddaten bei zusätzlichem Material wird jeweils der Aufbewahrungsort angegeben. Die Reihung der hier behandelten Gattungen und Arten erfolgt alphabetisch. Bei der Auflistung des untersuchten Materials werden entweder die genauen Funddaten, besonders bei Material außerhalb von Europa, oder nur die Länder aufgelistet. Inseln werden, da tiergeografisch besonders interessant, gesondert angeführt.
Gli Autori segnalano per il territorio delle Alpi Liguri 144 specie di Molluschi terrestri e 25 specie di Molluschi acquidulcicoli. L'elenco sistematico riporta, per ciascuna specie, eventuali sinonimie, segnalazioni di letteratura e di collezione e i risultati di ricerche di campagna effettuate dagli Autori negli anni 1977-84; inoltre, vengono fornite la geonemia e brevi considerazioni sulla distribuzionc geografica, le caratteristiche ecologichc ed eventuali problemi tassonomici. Segue un esame critico dei taxa di pteseilza dubbia o di incerta collocazione sistematica, ed un breve elenco delle specie presenti nelle aree circostanti l'area in esame, ma assenti in Alpi Liguri. La malacofauna terrestre delle Alpi Liguri (considerate in toto o nei tre Settori del Cuneese, Imperiese e Savonese) viene confrontata con quella di tre settori piu interni delle Alpi Occidentali (Alpi Marittime settentrionali, Alpi Cozie, Alpi Graie), di un settorc alpino meridionale (Alpi Marittime francesi) e di due settori appenninici (Appennino Ligure ed Aipi Apuane), mediante indici di similarit i di tipo binario (presenza-assenza di specie). Vengono inoltre confrontati tra loro gli spettri corologici delle aree sopracitate. L'area studiata non appare uniforme da1 punto di vista faunistico, ma diversamente caratterizzata nei diversi settori. Per la particolare posizione geografica e le peculiari caratteristiche paleoclimatiche, geomorfologiche ed ambientali, il popolamento malacologico delle Alpi Liguri si presenta qualitativamente vario ed ariicchito da correnti rnigratorie di diversa provenienza (alpina, W-mediterranes, appenninicii). Nella caratterizzazione della fauna e degli endemismi, sembra importante il ruolo di area di rifugio assunto dalle Alpi Liguri in epoca glaciale.
The cirripeds sampled by the N. O. Jean Charcot from the Azores region include thirty-four species: twenty lepadomorphs, eight verrucomorphs and six balanomorphs. Among these are two new species: Arcoscalpellum eponkos n.sp. and Tesseropora arnoldi n.sp. and several little known species. The family Verrucidae is revised, and a key to the genera is included. Verruca and Metaverruca are rediagnosed, two new genera are proposed: Newmaniuerruca n.g. and Costatoverruca n.g. A list of recent species of Verrucidae is provided, reported with keys to all of the species. Forty-five species of cirripeds are reported from the Azores region, of which one third are endemic.
