The genus Orobanche (Orobanchaceae) in Sicily
2011
The taxa of Orobanche occurring in Sicily and on the surrounding islets have been surveyed in the field and in herbaria. In total, 23 species occur in the region. O. litorea is found to be distinct from O. minor and O. thapsoides from O. canescens. O. crenata and O. ramosa are serious pests that cause heavy losses to broad bean and tomato cultures, respectively.
Lower Bashkirian fusulinoideans from the upper part of the Tagnana Formation (Carboniferous, NW Algeria)
2021
The upper member of the Tagnana Formation of the Djebel Bechar Group (informally the Tagnana-3 or Tagnana Ill member) yielded fusulinoideans and other related foraminifera of the genera Pseudoendothyra (rare), Pseudostajfella (Semistaffella) (rare), Millerella, Pseudonovel/a, Plectostaffella, Eostaffella and Mediocris. The presence of Eostaffellina (rare) and Endostaffella is doubtful. The difference between Millerella and Eostaffella cannot be adequately defined by evolute versus involute coiling. Pseudonovella Kireeva, 1949 is redefined to include Seminovella Rauzer-Chernousova, 1951. The foraminifera are from two samples, one from close to the top and the other from near the base of the …
Pleurotus eryngii var. thapsiae var. nov. from Sicily
2002
Field investigation in the Sicilian territory allowed the study of Pleurotus eryngii basidiomata growing in association with Thapsia garganica. The evaluation of morphological, ecological, distribution and isozyme, and PCR-RAPD data together with a revision of Bresadola's herbarium specimens kept in the Herbarium Botanische Staatssamlung (M) led to the description of a new variety, Pleurotus eryngii var. tahpsiae var. nov.
Molecular markers for systematic identification and population genetics of the invasive Ponto-Caspian freshwater gammarid Dikerogammarus villosus (Cr…
2006
The Ponto-Caspian amphipod, Dikerogammarus villosus, is an invasive species of many European rivers. First, we show that size difference of nrDNA ITS1 allows discriminating D. villosus from Dikerogammarus bispinosus, a closely related but morphologically hardly distinguishable species. Second, we present two types of polymorphic markers for D. villosus, three microsatellites and two single nucleotide polymorphisms (SNPs) of mtDNA COI gene, which were scored by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP). These markers will be very useful in studying population genetics of D. villosus.
Hieracium busambarense, a new species of the sect. Grovesiana (Asteraceae) from Sicily (Italy)
2013
Hieracium busambarense (Asteraceae), a new species from calcareous-dolomite cliffs of Rocca Busambra (western Sicily, Italy) is described and illustrated here.
