Naturalization and spread of the alien species Ozognathus cornutus (LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae) in Italy
2021
AbstractOzognathus cornutus(LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae), species native to North America, is a saproxylophagous species and is known to feed on decaying tissues within conspicuous galls and on vegetal decaying organic material such as dried fruits or small wood shavings and insect excrements in galleries made by other woodboring species. A few years after the first record in 2011, its naturalization in Italy is here reported. The insect was found as successor in galls ofPsectrosema tamaricis(Diptera Cecidomyiidae),Plagiotrochus gallaeramulorum,Andricus multiplicatusandSynophrus politus(Hymenoptera Cynipidae).The galls seem to have played an important ecological role in…
Nicodemia madagascariensis(Lam.) R. Parker (Family Scrophulariaceae), a casual alien plant new to Italy
2016
In this note the authors report the first case of naturalization of the Malagasy smoke bush within Italian territory. Along with a description of the abiotic and biotic characteristics of the invaded site, the current demographic and dynamic trends of the detected population by means of growth-ring analysis was also assessed. Moreover, an overview on the history of its introduction in Europe is provided, underlining the key role played by the Mediterranean cities with respect to the acclimatization and spread of alien tropical and subtropical plants. Due to its low frequency under cultivation, the Malagasy smoke bush should not behave as an invader in the future; on the other hand, its abil…

New records of Asteraceae for the non-native flora of Tunisia and north Africa with some nomenclatural remarks
2022
International audience; Sixteen new Asteraceae are added to the non-indigenous flora of Tunisia. Six of them (Dimorphotheca ecklonis, Gaillardia pulchella, Gazania linearis var. linearis, Guizotia abyssinica, Rudbeckia triloba and Tithonia diversifolia) are also new for the flora of North Africa. Chrysanthemum morifolium is here first reported for the Mediterranean Basin. Seven genera (Argyranthemum, Bidens, Dimorphotheca, Gaillardia, Guizotia, Rudbeckia and Tithonia) are recorded for the first time for the vascular flora of Tunisia. Most of these species escaped from gardens and pots and became casual along roadsides and/or disturbed areas after cypsela dispersion (except for Chrysanthemum…
The Biopolitical Logics of Settler Colonialism and Disruptive Relationality
2016
This essay argues that the biopolitical logics of settler colonialism function according to a naturalization in Western thought of politics as a project of hierarchically ordering life in relation to the sphere of politics. Significantly, such a mode of thinking discredits socio-political orders that operate on the basis of a non-hierarchical place-based relationality of all life forms including the land. Through a reading of Foucault and Agamben in their use of Aristotle, I want to show how hierarchy as a principle of the political is already implemented in the premise they draw upon for analyzing the biopolitical. In the same way it remains unrecognized in their analysis of biopolitics, …
First record of Heptapleurum arboricola Hayata (Araliaceae) as a casual non-native woody plant in the Mediterranean area
2021
I report here the first record of Heptapleurum arboricola Hayata (syn. Schefflera arboricola (Hayata) Merr.) (Araliaceae) as a casual non-native plant throughout the Mediterranean area. I observed the natural regeneration in urban areas at Castellammare del Golfo, a small coastal town in north-west Sicily (Mediterranean Italy). Due to the lack of self-sustaining populations and the short-term observational period, Heptapleurum arboricola should be considered as a casual species according to the classification of non-native plants. The detection of early signs of naturalization of non-native plants is of crucial importance for the management and control of invasive species. The main abiotic …
Notes about the naturalization in Sicily of Paulownia tomentosa (Paulowniaceae) and remarks about its global spread
2019
Paulownia tomentosa is native to different regions of East Asia. Here, the first case of natural regeneration in Sicily is reported. Although Paulownia is not still invading typically Mediterranean areas, mainly due to ecological constraints, its recognized invasiveness at a global level imposes the need to monitor the ongoing process.
Regole. Un saggio di psicodeontica
2022
In this article, I first introduce a naturalistic method of inquiry in meta-normative issues, that, following a suggestion by B. Celano, I call “psychodeontics”. I then provide an example of how the method works, focusing on three aspects of the phenomenon of rules and rule-guided behaviour: the fact that rules are reasons for action, the relation between rules and habits, and the “entrenchment” of rules.
Polityczność kwestii światopoglądowych w ujęciu dyskursywnym
2014
One of the dimensions of axiological values’ and agendas’ presence in the public sphere is seeing worldview as being political. Due to the nature of the phenomenon of belief as well as the category of politics, proposed consideration of these issues in the analysis of political science may be a discursive approach. Mechanisms which are revealing on the basis of discourse allow to specify categories of naturalization and pragmatism as the two basic types of articulation. As a result, we can identify examples of the implications of this phenomenon that have been identified in the form of SEP (somebody’s else problem) and tensions within the public-private dichotomy.
