Early detection and rapid response are essential to deal effectively with new introductions of invasive alien species (IAS). Citizen science platforms for opportunistic recording of species are increasingly popular, and there is potential to harvest their data for early detection of IAS, but this has not been tested.
We evaluated the potential of d...
In this contribution, new data concerning the distribution of vascular flora alien to Italy are presented. It includes new records, exclusions, and status changes from casual to naturalized or invasive for Italy or for Italian administrative regions for taxa in the genera Acacia, Akebia, Allocasuarina, Aloë, Brachychiton, Convolvulus, Freesia, Gled...
Inventorying non-native species in continental Ecuador is still in its infancy. The only attempt to date to produce a list of non-native species for continental Ecuador is the one published in the Global Register of Introduced and Invasive Species database, reporting 737 alien species, of which 577 species were vascular plants. The aim of this stud...
Monitoring the expansion of invasive non-native plants under current and future climatic conditions is crucial for understanding biodiversity threats, addressing the ecological impact, and developing effective management strategies. This study focuses on modelling the expansion and distribution of Senecio inaequidens DC. on the island of Sardinia (...
Given the high number of non-native plants that are being introduced worldwide and the time required to process formal pest risk analyses, a framework for the prioritization of management actions is urgently required. We therefore propose a framework for a replicable and standardized prioritization for management actions (eradication, control and m...
A large number of non‐native trees (NNTs) have been introduced globally and widely planted, contributing significantly to the world's economy. Although some of these species present a limited risk of spreading beyond their planting sites, a growing number of NNTs are spreading and becoming invasive leading to diverse negative impacts on biodiversit...
The decline of pollinator insects in various parts of the world has increased the interest in studies on bee sampling. Because pollinator management and conservation policies depend on data representing their communities, knowledge of the systematic bias of sampling methods in relation to surrounding habitat is fundamental. This study examined the...
Standardized terminology in science is important for clarity of interpretation and communication. In invasion science – a dynamic and rapidly evolving discipline – the proliferation of technical terminology has lacked a standardized framework for its development. The result is a convoluted and inconsistent usage of terminology, with various discrep...

Acacia dealbata and A. mearnsii are two invasive species found in coastal, mountain, and riparian Mediterranean habitats. Seed biology and germination traits are important drivers of the competitive performance of plants and may significantly contribute to biological invasions. The seeds of Acacia s.l. have physical dormancy due to an impermeable e...
Natural and anthropogenic disturbances are key factors in forest vegetation dynamics. Forest disturbance regimes are rapidly changing, with increasing magnitude and frequency of extreme events such as pathogen invasions , wildfires and windstorms, possibly as a consequence of climate change [1]. In October 2018, the "Vaia" storm hit the Eastern Ita...

L’ateneo di Sassari, le scuole secondarie superiori di città e provincia, la rete di associazioni scientifiche Scienza in Movimento, insieme come una unica squadra, si sono preparati a vincere la sfida che la situazione di pandemia ha proposto organizzando la versione online dell’atteso evento di Public Engagement Scienza in Piazza, arrivato quest’...
In this study, we analyzed the effects of grazing on native and endemic plant diversity, as well as its relationship with pastoral value along a gradient of abiotic and biotic factors and types of land management in a mountainous area of central-eastern Sardinia, Italy. Plant diversity was estimated by conducting a floristic survey within plots. In...
Biological invasions and climate pose two of the most important challenges facing global biodiversity. Certainly, climate change may intensify the impacts of invasion by allowing invasive plants to increase in abundance and further expand their ranges. For example, most aquatic alien plants in temperate climate are of tropical and subtropical origi...
The number of alien species arriving within new regions has increased at unprecedented rates. Managing the pathways through which alien species arrive and spread is important to reduce the threat of biological invasions. Harmonising information on pathways across individual sectors and user groups is therefore critical to underpin policy and action...
Sustainably managed non-native trees deliver economic and societal benefits with limited risk of spread to adjoining areas. However, some plantations have launched invasions that cause substantial damage to biodiversity and ecosystem services, while others pose substantial threats of causing such impacts. The challenge is to maximise the benefits o...

The integration of international, national and local regulations is one of the fundamental steps for preventing, controlling and managing biological invasions. The aim of the present study is to present and analyse, for the first time, the list of all non-native plant species that are regulated in Italy by the European, Italian and regional legisla...
Emerging technologies such as high-resolution Unmanned Aerial Vehicles (UAVs) surveys combined with object-based image analysis, and field surveys could represent a reliable, precise, and effective tool to support land management in agricultural systems. The technological advances of UAVs can also promote the detection and regular monitoring of inv...
Among the main objectives of “Precision Farming”, there is a more rational use of plant protection products, including a better application in the field. The benefits that can be achieved are various: from best product quality and reduced costs, up to an increase in productivity with considerable advantages both from an economic point of view and i...
The accidental introduction of alien plants through contaminated seed is a source of new incursions and subsequent invasions that can impact natural habitats, agriculture and forestry. While seed lots for agricultural crops are often well regulated through a certification process, the trade of many other types of seeds is largely unregulated. Here...

Le due specie, native della zona sud-orientale dell' Australia, sono state introdotte nel Mediterraneo durante il XIX secolo, principalmente a scop...
Acacia mearnsii De Wild. (De Wildeman 1925), chiamata anche mimosa nera, è una fanerofita originaria dell’Australia sudorientale, appartenente alla famiglia delle Fabaceae, sottofamiglia Caesalpinioideae (The Legume Phylogeny Working Group 2017). Ha generalmente portamento arboreo, un ciclo vitale relativamente breve (<100 anni) e in Sardegna raggi...
One of the most important issues for controlling the spread of invasive species is public awareness (Dehnen-Schmutz et al. 2018). Passively, the public are responsible for the spread of invasive species, for example by moving dirty boats from one water body to another. But they also actively spread invasive species by releasing them in the wild. Th...

It includes new records, confirmations, and status changes for Italy or for Italian administrative regions of taxa in the genera Abies, Actinidia, Aloe, Amaryllis, Anredera, Arctotheca, Bidens, Cardiospermum, Celosia, Commelina, Cotoneaster, C...
Standardized tools are needed to identify and prioritize the most harmful non-native species (NNS). A plethora of assessment protocols have been developed to evaluate the current and potential impacts of non-native species, but consistency among them has received limited attention. To estimate the consistency across impact assessment protocols, 89...
Species in the grass family (Poaceae) have caused some of the most damaging invasions in natural ecosystems, but plants in this family are also among the most widely used by humans. Therefore, it is important to be able to predict their likelihood of naturalisation and impact. We explore whether plant height is of particular importance in determini...
The present Technical Note addresses “Acacia saligna” and/or “Acacia saligna s.l.” (s.l. = sensu lato - in the broad sense) (also abbreviated as A. saligna) both indicating the species complex, i.e. the whole group of subspecies (or lower taxa, such as, e.g. cultivated varieties, cultigens and provenances) that have been described for the entity Ac...

Action pour Limiter les risques de diffusion des espèces Introduites Envahissantes en Méditerranée
Forty South American aquatic plant species were selected and categorised in four a priori status classes (alien naturalised, alien invasive, native and absent) according to expert opinion, for 16 South American regions (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Falklands Islands, French Guiana, Galapagos, Guyana, Paraguay, Peru, South G...
The Global Biodiversity Information Facility (GBIF) is at the moment one of the largest and most widely used biodiversity databases. Nevertheless, there are still some limitations, e.g. in terms of plant species status (native vs. non-native) and geographic resolution of records. At the same time, it is well known that alien plant invasions in inla...
Much has been done to address the challenges of biological invasions, but fundamental questions (e.g., which species invade? Which habitats are invaded? How can invasions be effectively managed?) still need to be answered before the spread and impact of alien taxa can be effectively managed. Questions on the role of biogeography (e.g., how does bio...
Presentation of poster in the SIL 2016, 32nd Congress of the International Society of Limnology, 31July-5 August 2016,Torino (Italy)
Alien plant invasions in inland freshwaters can alter community structure, ecosystem functions and services with significant negative impacts on biodiversity and human activities. National inventories of aquatic alien plants are a fundamental basis for prioritization, risk analysis and management and provide substantial insights to our understandin...
Prevention and early detection are considered to be the most effective means of managing non-native invasive species that have serious ecological and economic impacts. Consequently, the study of those taxa that are still in an early stage of invasion but are highly likely to spread and to have a significant adverse impact in future is becoming an i...
