Typification of the Presl’s name Calamintha canescens (Lamiaceae)

2021

Calamintha canescens is a taxon described in the “Flora Sicula” by K. B. Presl (1826), following the visit made to Sicily a few years earlier (March-July 1817). In the protologue Presl does not report any data on the distribution in Sicily of this taxon that will be almost completely forgotten in later floristic works. Only Nyman (1881) and later Šilić (1979) consider it as a variety respectively of Calamintha nepeta (L.) Savi and C. glandulosa (Req.) Benth. Following the review of a group of critical European taxa belonging to the genus Clinopodium L., lately Melnikov (2016) recovers the ancient taxon Calamintha canescens C. Presl and transfers it to the genus Clinopodium L. Also, the auth…

New Light on Parasorex Depereti (Erinaceomorpha: Erinaceidae: Galericini) from the Late Messinian (MN 13) of the Monticino Quarry (Brisighella, Faenz…

2019

Abstract A large-sized species of Parasorex is common in the MN 13 mammal assemblages from the uppermost Messinian sandy-marly fissure fillings within the Gessoso Solfifera Formation at Brisighella (Northern Apennine). This erinaceid has been classified as Galerix sp. in the first papers on the Brisighella fauna. Later, it was described in detail in an unpublished Ph.D. dissertation by Fanfani (1999), who referred it to Galerix depereti. Van den Hoek Ostende (2001) included G. depereti in the genus Parasorex, Parasorex depereti has been described by Crochet (1986) on scarce material from a few Early Pliocene (MN 14–15) localities of southern France and Spain. Parasorex cf. depereti has been…

Prvi nalazi dinoflagelata roda Dicroerisma (Actiniscales, Dinophyceae) na Sredozemnom moru

2011

This study is the first to describe and illustrate the dinoflagellate genus Dicroerisma in the Mediterranean Sea. Twenty individuals ascribed to Dicroerisma psilonereiella were encountered. The highest abundance (12 cells L-1) was recorded in the Balearic Sea at 50 m depth. Other specimens were found in subsurface waters (>75 m depth, with some records at 250 m depth) in the Ionian and Levantine Basin. These findings suggest that Dicroerisma is a widespread genus and its presence has gone unnoticed due to its small size, deep water distribution and misidentification with other gymnodinioid cells.

Fine-grain beta diversity in Palaearctic open vegetation: variability within and between biomes and vegetation types

2021

Aims: To quantify how fine-grain (within-plot) beta diversity differs among biomes and vegetation types. Study area: Palaearctic biogeographic realm. Methods: We extracted 4,654 nested-plot series with at least four different grain sizes between 0.0001 m² and 1,024 m² from the GrassPlot database spanning broad geographic and ecological gradients. Next, we calculated the slope parameter (z-value) of the power-law species–area relationship (SAR) to use as a measure of multiplicative beta diversity. We did this separately for vascular plants, bryophytes and lichens and for the three groups combined (complete vegetation). We then tested whether z-values differed between biomes, ecological-physi…

What have we learnt about board gender diversity as a business strategy? The appointment of board subcommittees

2018

This is the pre-peer reviewed version of the following article: What have we learnt about board gender diversity as a business strategy? The appointment of board subcommittees, which has been published in final form at https://doi.org/10.1002/bse.2226. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions. This paper explores whether a board's gender diversity influences the voluntary formation of its board subcommittees. Female board directorship may become a business strategy for firms if it affects the appointment of board subcommittees. We hypothesize that the voluntary creation of board subcommittees is affe…

The body fables in Babrius, Fab. 134 and 1 Corinthians 12: Hierarchic or democratic leadership in crisis management?

2021

Body metaphors and body fables were frequently used in ancient discourse for social communities and politics. This article will examine a body fable by the Greek fabulist Babrius (Babrius, Fab . 134) that has been overlooked in research so far. It shows a remarkable similarity to 1 Corinthians 12 through the use of central terms such as σῶμα and μέλος or personified speaking body parts such as an eye and head. Even if no literary direct dependence is claimed, the text, which was written at about the same time as 1 Corinthians, sheds light on Paul’s understanding of the body fable. It becomes apparent, however, that the rhetorical function is fundamentally different in the two texts. Whilst …

Właściwości negocjacji w Unii Europejskiej: wybrane aspekty teoretyczne

2015

Artykuł koncentruje się na wybranych, najbardziej znaczących, aspektach teoretycznych właściwości negocjacji w Unii Europejskiej. Wśród nich znajdują się właściwości dotyczące: dużej liczby i różnorodności aktorów negocjacji; specyficznego przedmiotu negocjacji skutkującego wielopoziomowością i wieloaspektowością negocjacji w UE; wieloetapowością procesu negocjacji w UE, który angażuje różnorodnych aktorów na różnych poziomach i w zależności od tych płaszczyzn wymaga odmiennych aktywności negocjacyjnych i wreszcie procesów top-down i bottom-up jako determinant negocjacji w Unii Europejskiej. The focus of the paper is the selected, most significant theoretical aspects of negotiations conduct…

The genetic heritage of Alpine local cattle breeds using genomic SNP data

2020

Abstract Background Assessment of genetic diversity and population structure provides important control metrics to avoid genetic erosion, inbreeding depression and crossbreeding between exotic and locally-adapted cattle breeds since these events can have deleterious consequences and eventually lead to extinction. Historically, the Alpine Arc represents an important pocket of cattle biodiversity with a large number of autochthonous breeds that provide a fundamental source of income for the entire regional economy. By using genotype data from medium-density single nucleotide polymorphism (SNP) arrays, we performed a genome-wide comparative study of 23 cattle populations from the Alpine Arc an…

On the origin and diversification of Podolian cattle breeds: testing scenarios of European colonization using genome-wide SNP data

2021

AbstractBackgroundDuring the Neolithic expansion, cattle accompanied humans and spread from their domestication centres to colonize the ancient world. In addition, European cattle occasionally intermingled with both indicine cattle and local aurochs resulting in an exclusive pattern of genetic diversity. Among the most ancient European cattle are breeds that belong to the so-called Podolian trunk, the history of which is still not well established. Here, we used genome-wide single nucleotide polymorphism (SNP) data on 806 individuals belonging to 36 breeds to reconstruct the origin and diversification of Podolian cattle and to provide a reliable scenario of the European colonization, throug…
