Lectotypification of the name Scrophularia tenuipes Coss. (Scrophulariaceae)
2019
The present contribution is part of an ongoing project for the investigation of the Algerian-Tunisian Flora (see e.g., El Mokni et al. 2014, 2015a, 2015b, 2015c; El Mokni & Iamonico 2018, El Mokni & Domina 2019). Special attention is dedicated to the endemic component of this flora and its type localities (loci classici), that are considered a rich source of biogeographical information (Brundu et al. 2015).

Forty-five years later: The shifting dynamic of traditional ecological knowledge on Pantelleria Island, Italy
2016
In 1969, Galt and Galt conducted an ethnobotanical survey in the community of Khamma on the volcanic island of Pantelleria, Italy. Since then, a number of botanical studies concerning the local wild flora and cultivation of the zibibbo grape and capers have been conducted, but none have investigated traditional ecological knowledge (TEK) regarding the use of wild plants and fungi. We documented the current TEK and practices concerning wild plants and fungi on the island, focusing on uses related to food and medicine with 42 in-depth interviews in six communities in June 2014. Our aim was to examine shifts in TEK, represented in terms of loss or gain of specific species uses, in comparison t…
Dimensions of invasiveness: Links between local abundance, geographic range size, and habitat breadth in Europe's alien and native floras.
2021
Understanding drivers of success for alien species can inform on potential future invasions. Recent conceptual advances highlight that species may achieve invasiveness via performance along at least three distinct dimensions: 1) local abundance, 2) geographic range size, and 3) habitat breadth in naturalized distributions. Associations among these dimensions and the factors that determine success in each have yet to be assessed at large geographic scales. Here, we combine data from over one million vegetation plots covering the extent of Europe and its habitat diversity with databases on species' distributions, traits, and historical origins to provide a comprehensive assessment of invasive…
Poa jubata (Poaceae), a rare Balkan species, first record for the Italian flora
2019
Abstract Poa jubata A. Kern., an annual South-eastern European species, is reported for the first time from Italy. It is a therophyte linked to temporary ponds with soils flooded during the winter period. It is a very rare and enigmatic species, currently known only from a few localities of the Balkan Peninsula. Recently, it was surveyed in an Apulian wetland, near Brindisi, where it grows with several other annual hygrophytes. For its taxonomical isolation, it is included in a monospecific section, as P. sect. Jubatae. In addition to a detailed description, the chromo-some complement (2n = 14) of this species is examined for the first time and a new iconography is provided.

A preliminary approach for modelling the effects of cropping systems on the dynamics of broomrape ( Phelipanche ramosa) in interaction with the non-p…
2011
International audience; The current decrease in herbicide use may increase and diversify weed flora in crops as well as companion bioagressors spreading via weeds. Among these bioagressors is Phelipanche ramosa (L.) Pomel, a parastic plant which is very harmful on oilseed rape. The objective of the present work was to develop a new model (called PheraSys) of the effects of cropping systems on parasite dynamics, in interaction with non-parasitic weed hosts. The structure of this first model version was based on models developed for other parasitic plants and on FlorSys which quantifies the effects of cropping systems on non-parasitic weed flora. PheraSys was parametrized with preliminary val…
An updated checklist of the vascular flora alien to Italy
2018
An updated inventory of the vascular flora alien to Italy, providing details on the occurrence at regional level, is presented. The checklist includes 1597 species, subspecies, and hybrids, distributed in 725 genera and 152 families; 2 taxa are lycophytes, 11 ferns and fern allies, 33 gymnosperms, and 1551 angiosperms. 157 taxa are archaeophytes and 1440 neophytes. The alien taxa currently established in Italy are 791 (570 naturalized and 221 invasive), while 705 taxa are casual aliens, 4 are not assessed, 7 are of unknown regional distribution, 47 have not been confirmed in recent times, 3 are considered extinct or possibly extinct in the country, and 40 are doubtfully occurring in Italy. …
