Narrow endemic species Bellevalia webbiana shows significant intraspecific variation in tertiary CSR strategy

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology (2018)

Giovanni Astuti Daniela Ciccarelli Francesco Roma‐Marzio Alberto Trinco Lorenzo Peruzzi

Insufficient attention has been devoted to inter-population and inter-individual variability of CSR strategy. Hence, we selected Bellevalia webbiana as a case study for answering the following questions: (1) is there a significant intraspecific variability in leaf traits determining a significant intraspecific variability in CSR parameters, even in a narrow endemic species with a relatively homogeneous habitat? (2) If yes, does this provide a significant intraspecific CSR strategy variation? For five populations, we calculated C, S, and R parameters using leaf area, leaf fresh weight, and leaf dry weight for 10 individuals each. We found that Bellevalia webbiana is a "CS" species considering single individuals, populations or the "whole species". However, our data suggest a significant loss of information if the species is plotted as a single average point, and attest for population-based plasticity, highlighting the applicability of CSR theory at micro-evolutionary scale. When heterogeneity in coefficients of variation (CVs) is higher for the "whole species", "deviant" populations should be retained as additional points. Hence, we advise to perform CSR analyses on more populations and verify the applicability of a single ternary set to represent the "whole species" using PERMANOVA, complemented by simple CV comparison for each parameter.

Distribution of the genus Sternbergia Waldst. & Kit. (Amaryllidaceae) in Tuscany (central Italy)

Flavio Frignani Francesco Geri G. Gestri Lorenzo Peruzzi

The authors report an updated distribution of the genus Sternbergia Waldst. & Kit. (Amaryllidaceae) in Tus- cany by the analysis of herbarium specimens, bibliographic references and records in the field. S. colchiciflora occurs in six localities, four in southern Tuscany and two in northern Tuscany. One out of them, the first in Firenze province, is here recorded. On the contrary, S. lutea is widespread in the region, but the distinction between natural populations and those escaped from cultivation is not always certain. Habitat suitability model at regional level for S. colchiciflora is also reported. Sternbergia Waldst. & Kit. ( Amaryllidaceae) in Toscana, tramite l'analisi di campioni d'erbario, riferimenti bibliografici ed indagini di campo. S. colchiciflora risulta presente in sei localita, quattro nella Toscana meridionale e due nella Toscana settentrionale. Una di queste stazioni, la prima in provincia di Firenze, viene qui segnalata. S. lutea risulta invece maggiormente diffusa, ma non e sempre agevole distinguere tra popolamenti naturali ed altri sfuggiti alla coltivazione. Viene inoltre presentato un modello di distribuzione potenziale a livello regionale per S. colchiciflora. Parole chiave - Flora, fitogeografia, distribuzione potenziale, Sternbergia, Toscana.

Different observers introduce not negligible biases in comparative karyomorphological studies

Comparative Cytogenetics (2024)

Lorenzo Peruzzi Jacopo Franzoni Manuel Tiburtini Emanuela Abidi Emiliano Alù

Within a practical course of cytotaxonomy organized in Pisa (Italy) on February 2024 by the Group for Floristics, Systematics and Evolution of the Italian Botanical Society, we tested whether using image analysis softwares possible biases are still introduced by different observers. We conclude that observer bias selectively applies in possibly overestimating the length of short arms in a karyotype. As a consequence, the parameters most sensitive to these possible errors are CV CI and CV CL , and to a less degree M CA and THL. To achieve more stable results among observers, a still lacking standardized measurement protocol could be helpful.

An updated checklist of the vascular flora native to Italy

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology (2018)

Fabrizio Bartolucci Lorenzo Peruzzi Gabriele Galasso Antonella Albano Alessandro Alessandrini

An updated inventory of the native vascular flora of Italy, providing details on the occurrence at regional level, is presented. The checklist includes 8195 taxa (6417 species and 1778 subspecies), distributed in 1092 genera and 152 families; 23 taxa are lycophytes, 108 ferns and fern allies, 30 gymnosperms and 8034 angiosperms. The taxa currently occurring in Italy are 7483, while 568 taxa have not been confirmed in recent times, 99 are doubtfully occurring in the country and 19 are data deficient. Out of the 568 not confirmed taxa, 26 are considered extinct or possibly extinct.

Was Charles Darwin right in his explanation of the ‘abominable mystery’?

Italian Botanist (2018)

Sergio Sgorbati Marco D’Antraccoli Sandra Citterio Rodolfo Gentili Lorenzo Peruzzi

The site and time of origin of angiosperms are still debated. The co-occurrence of many of the early branching lineages of flowering plants in a region somewhere between Australia and the SW Pacific islands suggests a possible Gondwanan origin of angiosperms. The recent recognition of Zealandia, a 94% submerged continent in the east of Australia, could explain the discrepancy between molecular clocks and fossil records about the age of angiosperms, supporting the old Darwinian hypothesis of a “lost continent” to explain the “abominable mystery” regarding the origin and rapid radiation of flowering plants.

From Bullettino della Società Botanica Italiana to Italian Botanist, passing through Informatore Botanico Italiano. A 128 years-long story

Italian Botanist (2016)

Lorenzo Peruzzi Consolata Siniscalco

In 1888, concomitant with the foundation of the Italian Botanical Society, a section called Bullettino della Società Botanica Italiana appeared in the last pages of each issue of volume 20 of the Nuovo Giornale Botanico Italiano (currently the international journal Plant Biosystems).Since the very beginning, this was the place where the formal proceedings of the Society and a summary of the scientific contents of the Society meetings were published.Since then, albeit without an autonomous numbering, the bulletin was regularly published several times a year.From 1894 and until 1926, along with the first volume of the new series of Nuovo Giornale Botanico Italiano, the bulletin started to appear only once a year, at the end of the last issue.Between 1927 and 1961 its name was changed to Rendiconti delle Sedute e Brevi Comunicazioni, but its publication continued.Further details on these intricate and puzzling first decades of the bulletin can be found in Maugini (1988).When, in 1962, the journal changed its name again to Giornale Botanico Italiano, the bulletin also changed its name back to Bollettino della Società Botanica Italiana, and remained as such up to 1968.During the Congress of the Italian Botanical Society held in Piacenza in September 1968, the General Assembly voted for a full separation of the bulletin from Giornale Botanico Italiano, so that it became an
