Contribution to a Taxonomic Revision of the Sicilian Helichrysum Taxa by PCA Analysis of Their Essential-Oil Compositions

2016

The chemical profile of the essential oils in ten populations of the genus Helichrysum Mill. (Asteraceae), collected in the loci classici of the nomenclatural types of the taxa endemic to Sicily, were analyzed. Our results confirm that the analysis of secondary metabolites can be used to fingerprint wild populations of Helichrysum, the chemical profiles being coherent with the systematic arrangement of the investigated populations in three main clusters, referring to the aggregates of H. stoechas, H. rupestre, and H. italicum, all belonging to the section Stoechadina. The correct nomenclatural designation of the investigated populations is discussed and the following two new combinations ar…

Taxonomic identity, geographic distribution and commercial exploitation of the culinary-medicinal mushroom Pleurotus nebrodensis

This work provides an updated overview of an investigation carried out in Europe and elsewhere on the culinary-medicinal mushroom Pleurotus nebrodensis. In particular, the taxonomic identitiy of P. nebrodensis and other related oyster mushrooms with entirely white to cream basidiomata that grow on different plants of the family Apiaceae, is clarified. The differences in the cultivation techniques, the quality of product sold and the sales price in Europe and Asia are also highlighted. Taking also into consideration the importance of P. nebrodensis from the medicinal point of view, it appears appropriate to proceed with a verification of the commercial strains currently available in the inte…

A molecular study of Neophyllaphis varicolor (Hemiptera, Aphididae) in Costa Rica

2019

The genus Neophyllaphis (Takahashi) (Aphididae: Neophyllaphidinae) is composed of 18 species; however, in the Americas only nine species have been reported previously. A new species, Neophyllaphis varicolor Miller & Halbert, was described in 2014 in USA. Colonies resembling those of this new species have been observed in Costa Rica on Podocarpus spp. In order to determine if N. varicolor is also present in Costa Rica, we sampled Neophyllaphis colonies from Podocarpus falcatus and P. chinensis. Additionally, we sampled individuals from Podocarpus sp. in Spain and Vietnam. DNA of each sample was extracted and used to amplify and sequence the cytochrome c oxidase subunit I (COI) and elongation…

Historicizing Divergence: A Comparative Analysis of the Revolutionary Crises in Russia and Finland

2016

Beginning 1917, Russia and Finland both experienced revolutionary situations, the seizure of power by radical political groups, and civil wars. However, the ultimate outcomes of the revolutionary crises in the two countries turned out to be different: the Russian Bolsheviks won the struggle for power whereas the Finnish Red Guard suffered a defeat. Why did the radical socialists win in Russia but lose in Finland? This chapter argues that the Russian revolutionaries benefited from the existence of two coalition alliances that had not fully materialized in Finland: the workers–soldiers’ alliance, which was critical for the radicals’ seizure of power, and the workers–peasants’ alliance, which …

Precarious work and social protection: between flexicurity and social pollution

2019

The chapter explores the possibility of changing the way in which any social and legal system guarantees social protections for the weakest workers. To do so it elaborates a unique functional set for classifying all kind of precariat, which it names the ‘un[der]-protected workers’. The issue of the precariat is held as an imbalance in the flexicurity balance, considered akin to pollution in the social environment: so-called social pollution. The proposed method to counterbalance the lack of security/protection and rebalance flexicurity is a ‘(non-wage) Social Security (virtual or) Fake (Pigouvian) Tax’ (the SSFT). The idea is that this device either forces companies to hire through SERs (wh…

ICTV Virus Taxonomy Profile: Polycipiviridae

2019

Polycipiviridae is a family of picorna-like viruses with non-segmented, linear, positive-sense RNA genomes of approximately 10–12 kb. Unusually for viruses within the order Picornavirales, their genomes are polycistronic, with four (or more) consecutive 5′-proximal open reading frames (ORFs) encoding structural (and possibly other) proteins and a long 3′ ORF encoding the replication polyprotein. Members of species within the family have all been detected in ants or via arthropod transcriptomic datasets. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the Polycipiviridae, which is available at www.ictv.global/report/polycipiviridae.

Cracking the nut: Geographical adjacency of sister taxa supports vicariance in a polytomic salamander clade in the absence of node support

2008

The urodelan genus Lyciasalamandra, which inhabits a relatively small area along the southern Turkish coast and some Aegean islands, provides an outstanding example of a diverse but phylogenetically unresolved taxon. Molecular trees contain a single basal polytomy that could be either soft or hard. We here use the information of nuclear (allozymes) and mitochondrial (fractions of the 16S rRNA and ATPase genes) datasets in combination with area relationships of lineages to resolve the phylogenetic relationships among Lyciasalamandra species in the absence of sufficient node support. We can show that neither random processes nor introgressive hybridization can be invoked to explain that the m…

Análisis de las experiencias de presupuesto participativo de la Comunitat Valenciana a través de una taxonomía

2021

Después de casi treinta años de una de las experiencias de participación más innovadoras, al incluir en el proceso de decisión presupuestaria al ciudadano común, el Orçamento Participativo de Porto Alegre (Brasil) se ha paralizado y comienza a plantearse su futuro. Esta práctica que se inició con mucha euforia y esperanza (que se apreciaba incluso en las reflexiones académicas sobre ella), ha ido perdiendo a lo largo del tiempo impulso y adhesión en Brasil y, recientemente, ha empezado a cuestionarse su efectividad e impacto. En los últimos trabajos colectivos publicados en Brasil (Pires et al., 2011; Lavalle, 2011) se explica lo que empírica e intuitivamente ya se venía sospechando: no es …
