Notes on Shore Flies (Diptera: Ephydridae) from Finland and north-western Russia
2015
The recent checklist of the Ephydridae of Finland by Zatwarnicki and Kahanpää (2014) mentioned 13 ephydrid species as new for Finland without further details. This paper presents detailed records for those species and a few other species of interest. Four species are recorded for the first time from Russia. Trimerina indistincta Krivosheina, 2004 is herein considered as a new junior synonym of Trimerina microchaeta Hendel, 1932, syn. nov.
Notes on Selected Genera of Shore Flies (Diptera: Ephydridae), with Removals to Drosophilidae, Heleomyzidae and Milichiidae
2022
The following new taxonomic changes in nine tribes of Ephydridae are proposed: status at species level: Ditrichophora amoena (Duda, 1942); 2 resurrections from synonymy: Ptilomyia madeirensis Stuke, 2012, bona species, and P. orsovana (Enderlein, 1922), bona species; 10 new combinations: Allotrichoma communis (Malloch, 1934), comb. nov., Athyroglossa bettelai (Canzoneri, 1995), comb. nov., Ceropsilopa africana (Canzoneri & Meneghini, 1969), comb. nov., Ceropsilopa flavescens (Frey, 1958), comb. nov., Diclasiopa affinis (Tonnoir & Malloch, 1926), comb. nov., Diclasiopa flavitarsis (Tonnoir & Malloch, 1926), comb. nov., Diclasiopa senegalensis (Canzoneri, 1981), comb. nov., Ditrichophora amoe…
A revision of the Old World species of Leptopsilopa Cresson (Insecta: Diptera: Ephydridae)
2016
Diagnoses and illustrations of three Leptopsilopa species known in the Old World: L. africana Cresson, L. mutabilis Cresson and L. pollinosa (Kertesz) are provided. Three new synonyms are proposed: L. aurata (Canzoneri and Meneghini) and L. tibialis (Canzoneri and Meneghini) = L. africana; Psilopa confeteae Canzoneri and Munari = L. pollinosa. Three other species are removed from Leptopsilopa and combined with Athyroglossa, as A. leonensis (Canzoneri and Rampini), new combination, A. mianii (Canzoneri) new combination and A. rossii (Canzoneri and Raffone), new combination.
Study of the impact of viticultural practices on arbuscular mycorrhizal fungi associated with vines
2021
Arbuscular mycorrhiza, a mutualistic symbiosis established between plants andarbuscular mycorrhizal fungi (AMF), providesmany ecosystem services such as improved soilstructure, increased plant growth and nutrition,and improved tolerance to biotic and abioticstresses. However, intensive agricultural practicesand the use of phytosanitary products as forexample herbicide and fungicides, have a strongimpact on communities of soil microorganisms,including arbuscular mycorrhizal fungi, as well ason biological mechanisms within the ecosystem.This thesis wotk is part of the European Biovineproject supported by the European Commissionthrough the CORE Organic Cofund.The aim of this research work was …
Visual Literacy From the Perspective of the VTS Method
2017
The purpose of this article is to investigate visual literacy from the perspective of the VTS (Visual Thinking Strategies) method. The authors examine the viewpoints of seven American elementary school teachers on visual literacy and its meanings in the context of the VTS method. Data collection was done using a semi-structured questionnaire, which was followed by theory-driven content analysis. The authors emphasize that when supporting holistic development in a teaching context, it is the interconnected nature of aesthetics, growth and the learner’s learning which is more important than developing special skills, like visual literacy. In the teaching context visual literacy and language d…
Validation of chasmophytic syntaxa of colline and montane zones in Tajikistan (Middle Asia)
2016
AbstractEight syntaxa are validated with the previous names regarded as invalidly published according to the International Code of Phytosociological Nomenclature. The validation concerns syntaxa of rock plant communities of the Campanuletalia incanescentis order reported from the Pamir Alai mountains in Tajikistan. The majority of validated syntaxa represents association level, one is an alliance. All validations are conducted due to the invalidity of tables with typus releves according to art. 1 of the Code: they were not distributed as printed matter. The validated syntaxa are as follows: Caricion koshewnikowii, Scutellarietum hissaricae, Scutellarietum schugnanicae, Scutellarietum zaprja…
New syntaxa of tall-forb vegetation in the Pamir-Alai and western Tian Shan Mts. (Tajikistan and Kyrgyzstan, Middle Asia) – an addendum to Nowak et a…
2021
We validate eleven syntaxa (eight associations and three alliances) of tall-forb vegetation that were published earlier as nomina provisoria according to the International Code of Phytosociological Nomenclature. The validation concerns syntaxa of tall-forb vegetation of the class Prangetea ulopterae Klein 1987 reported from Pamir-Alai and western Tian Shan Mountains (Tajikistan and Kyrgyzstan). Taxonomic reference: Cherepanov (1995). Abbreviations: ICPN = International Code of Phytosociological Nomenclature.
The vegetation of mining dumps in SW-Sardinia
2005
The vegetation of mining dumps of SW-Sardinia includes several endemic or rare species, that have been confined to such artificial habitats by a millennial mining activity. The extreme edaphic specialisation of these species reflects with unusual fidelity the heterogeneity of substrata, therefore creating a system of plant communities that largely contributes to the environmental diversity of this part of the island. The phytosociological study presented in this paper recognized eight associations, distinguished by the cluster analysis in two main groups, the first including hemicrypto-chamaephytic vegetation, the second including nanophanerophytic garigues. Six associations are belonging t…
Are Red Lists really useful for plant conservation? The New Red List of the Italian Flora in the perspective of national conservation policies
2013
La nuova Lista Rossa della flora Italiana comprende tutte le "policy" specie italiane e altre specie di nota conservazione e comprende 400 taxa di cui il 65% sono minacciate di estinzione. La Lista Rossa si basa su un enorme data-set georeferenziato utile per gli scopi di conservazione. - The New Red List of the Italian Flora includes all the Italian policy species and other species of known conservation concerns for a total of 400 taxa, 65% of which are threatened with extinction. The Red List is based on a huge georeferenced data-set useful for conservation purposes. -
