Melampsora allii-fragilis f. sp. galanthi-fragilis reported for first time to cause rust on Galanthus plicatus in Latvia

2010

In Europe, Melampsora allii-fragilis f. sp. galanthi-fragilis (syn. Melampsora galanthi-fragilis) has been reported on leaves of snowdrop (Galanthus nivalis) in Romania (Savulescu, 1953; Bagyanarayana, 2005) and on Galanthus plicatus in Ukraine (Gutsevich, 1952). The GBIF Database has additional records of this fungus on G. nivalis from Austria, Czech Republic and France but the USDA SMML Specimens Database has also records from Hungary and Poland. According to this database, the established distribution area of M. allii-fragilis f. sp. galanthi-fragilis is ‘Central Europe’. Melampsora allii-fragilis f. sp. galanthi-fragilis belongs to the heteroecious rust fungi that require two hosts to c…

Dataset of trace elements concentrations in snow samples collected in Jelgava City (Latvia) in December 2020

2021

Abstract The data set provided in this article consist of two repeated data sets of chemical elements concentrations in snow samples. The snow samples were collected in Jelgava city at December 15th with 5 day exposition time. Snow samples were collected in 59 monitoring points in Jelgava city and in one sample in rural area monitoring point as control. The collected snow samples were melted, acidified with HNO3 and analysed with ICP-MS. The samples were analysed Aluminium (Al), Silicon (Si), Chrome (Cr), Manganese (Mn), Iron (Fe), Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As), Molybdenum (Mo), Cadmium (Cd), Barium (Ba), Tungsten (W), Lead (Pb). The collected data are with fundamental s…

Monitoraggio e controllo di insetti infestanti le collezioni dell’erbario dell’orto botanico di Palermo

2021

Gli erbari sono strumenti d’importante rilevanza scientifica che conservano esempi di piante rare, endemiche o estinte, e assumono essi stessi notevole interesse come beni culturali per il loro valore storico ed estetico. Gli erbari possono essere soggetti all’attacco di diverse specie d’insetti che danneggiano le piante essiccate (exsiccata) con la loro attività di alimentazione. Il controllo di queste infestazioni è spesso aggravato dalla difficoltà di poter mettere in atto trattamenti insetticidi. In tale contesto è opportuno adoperare adeguati strumenti di monitoraggio e controllo basati su sostanze attrattive feromonali o alimentari per una corretta gestione integrata degli erbari.…

TAXONOMIC, ECOLOGICAL AND CHOROLOGICAL REMARKS ON CLINOPODIUM MINAE (LAMIACEAE), CRITICAL AND RARE PLANT OF THE SICILIAN FLORA

2017

In a previous contribution (1) the finding in the wild of Clinopodium minae (Lojac.) Peruzzi & F.Conti [Bas. Calamintha minae Lojac.], a critical species close to Clinopodium corsicum (Pers.) Govaerts and well distinct from Clinopodium alpinum (L.) Kuntze subsp. nebrodense (A.Kern. & Strobl) Bartolucci & F.Conti was reported. It is a critical taxon, described by Lojacono, author of the most extensive work on the Sicilian flora (2) based on the examination of the collections of the Herbarium of Palermo (PAL!) (3). In the above cited note, the specific characters as well as the taxonomic relationships with other taxa were highlighted. At the same time, the location of a small population of C.…

Nomenclatural notes on the Polycarpon tetraphyllum aggregate (Caryophyllaceae)

2015

Nomenclatural notes on the aggregate Polycarpon tetraphyllum (Caryophyllaceae) are discussed. The names Hagaea alsinifolia, H. polycarpoides, Poycarpon colomense, P. diphyllum, and P. floribundum are typified, respectively, on an iconography by Boccone (lectotype), and specimens preserved in PAL (neotype), JE (lectotype), MA (Herbarium Cavanilles, lectotype), and COI (Herbarium Willkomm, lectotype). For the nomenclatural purposes, the names P. bivonae (nom. nov. pro P. polycarpoides), P. herniarioides (holotype in K), P. peploides (nom. superfl. et nom. illeg. according to the Arts. 52.1 and 52.2 of the ICN), P. polycarpoides subsp. catalaunicum (holotype in BC), and P. rotundifolium (holot…

Utilisation of barium-modified analcime in sulphate removal: Isotherms, kinetics and thermodynamics studies

2017

Abstract Analcime and commercial zeolite were employed as a precursor for preparing sorbent material for SO42− removal over barium modification. Three sorbents were prepared: barium-modified analcime (ANA-Na-Ba), barium-modified acid-washed analcime (ANA-Ac-Na-Ba) and barium-modified zeolite (ZSM5-Na-Ba). Of the prepared materials, ANA-Ac-Na-Ba was the most efficient sorbent material for SO42− removal, with a maximum sorption uptake of 13.7 mg g−1 at room temperature. Batch sorption experiments were performed to evaluate the effect of initial pH, initial SO42− concentration, sorbent dosage, temperature and contact time of sorption. Several isotherms were applied to describe the experimental…
