Pleurotus opuntiae revisited e An insight to the phylogeny of dimitic Pleurotus species with emphasis on the P. djamor complex

2018

Abstract The name Pleurotus opuntiae is indiscriminately used for describing mushrooms with white to off-white to white-grey pilei with short or absent stipe and dimitic hyphal system, which grow on plants of the genera Opuntia, Yucca, Agave, Phytolacca etc. However, the outcome of the present study evidences that this name should be reserved for specimens deriving from the Mediterranean area only; an epitype originating from Italy on Opuntia ficus-indica is designated. Pertinent material was sequenced by using the internal transcribed spacer region (ITS) and found to be phylogenetically related to P. djamor from Kenya and Nigeria, while members of the P. djamor complex from other continent…

A formal classification of the Lygeum spartum vegetation of the Mediterranean Region

2019

Aims: We examined all available literature and some unpublished data on the We examined all available literature and some unpublished data on the grasslands dominated by Lygeum spartum from Southern Europe and North Africa to produce a formalised classification of this vegetation and to identify the main factors determining its plant species composition. Location: Mediterranean Basin and Iberian Peninsula. Methods: We used a dataset of 728 releves, which were resampled to reduce unbalanced sampling effort, resulting in a dataset of 568 releves and 846 taxa. We classified the plots by TWINSPAN, interpreted the resulting pools, and used them to develop formal definitions of phytosociological …

Multivariate morphometric analysis of the Stipa turkestanica group (Poaceae: Stipa sect. Stipa)

2015

Based on numerical analyses of macromorphological characters (cluster analysis, principal coordinate analysis and principal component analysis), scanning electron microscopy observation of lemma and lamina micromorphology, as well as field observations, five taxa belonging to the Stipa turkestanica group have been recognized in the mountain area of Central Asia. They are S. turkestanica subsp. turkestanica, S. turkestanica subsp. trichoides, S. macroglossa subsp. macroglossa, S. macroglossa subsp. kazachstanica and S. kirghisorum. As a result of this study, we propose one new combination, S. macroglossa var. pubescens, and designate lectotypes for S. turkestanica subsp. trichoides and S. ma…

Stipa ×fallax (Poaceae: Pooideae: Stipeae), a new natural hybrid from Tajikistan, and a new combination in Stipa drobovii

2017

Stipa ×fallax nothosp. nov . (Poaceae), from western Pamir Alai Mts (Tajikistan), is described and illustrated. Field observation, numerical analyses of morphology, and pollen grain viability data show that it originated from hybridization between S. drobovii and S. macroglossa subsp. macroglossa , species representing sections Smirnovia and Stipa , respectively. Stipa ×fallax is morphologically close to S. ×alaica and S. ×hissarica , but is distinguished by its shortly pilose lower part of the awn and densely pubescent leaves. Characters distinguishing S. ×fallax from its parental species as well as similar hybrid taxa in section Smirnovia that also grow in Central Asia are presented. The …

Work places with stipend programme and its impact on poverty risk decrease: Case of Latvia

2012

The aim of the paper is to analyze theoretical concepts of poverty risk and to estimate the impact of the Workplaces with Stipend Programme (hereinafter WWS) on poverty risk decrease in Latvia. In order to assess the effects of the WWS three different surveys were carried out: of households with WWS participants, of experts in Latvian labour market issues, and of municipality representatives. The results were analyzed, together with analysis of statistical data. The paper concludes that in general the WWS has a very positive impact on WWS participants? household budgets (more than 95% of the WWS participants in all Latvian regions noted a significant impact of the WWS on their household bud…

Un nuovo sacello da Gela: fasi di frequentazioni e ipotesi sulla destinazione del culto

2020

L'articolo presenta un sacello suburbano lungo le pendici meridionali della collina dell'antica Gela, emerso a seguito delle indagini archeologiche condotte dalla Scrivente tra il 2001 e il 2002. Lo studio della stratigrafia archeologica e muraria ha permesso di identificarne le fasi di vita e il rapporto con le strutture sacre finitime. Vengono presentati anche i materiali rinvenuti, tra cui una stipe votiva, che consentono di avanzare delle riflessioni circa la destinazione del culto e il sistema delle pratiche rituali.
