It provides details on occurrence at administrative regional level and, for first time, floristic data San Marino. The checklist includes 1782 taxa (1673 species, 28 subspecies, 69 hybrids 12 cultivar groups not attributable specific binomial), distributed in 786 genera 159 families; 2 lycophytes, 13 ferns fern allies, 37 gymnosperms 1730 angiosperms. Among these, 154 archaeophytes 1628 neophytes. currently established 899 (649 naturalized 250 invasive), while 796 casual aliens, 1 assessed, 38 have been confirmed recent times, 4 considered extinct or possibly country, 40 doubtfully occurring Italy, unknown distribution 110 reported by mistake be excluded national level.

Prioritizing management actions for invasive non-native plants through expert-based knowledge and species distribution models

Ecological Indicators, Journal Year: 2024, Volume and Issue: 166, P. 112279 - 112279

Published: July 2, 2024

Given the high number of non-native plants that are being introduced worldwide and time required to process formal pest risk analyses, a framework for prioritization management actions is urgently required. We therefore propose replicable standardized (eradication, control monitoring) invasive plants, combining expert knowledge, current future climatic suitability estimated by species distribution models (SDMs), clustering ordination techniques. Based on consultation using Italy as case study, plant were selected three categories identified: eradication, containment, monitoring. Finally, two further classes priorities proposed each actions: "high" "low" priority. Overall, SDMs highlighted very Continental Mediterranean bioregions most plants. Cluster analysis revealed distinct clusters with varying levels Italian bioregions. 1 exhibited higher across all bioregions, whereas grouped in 2 predominantly featured areas. 3 showed lowest values. Two variability bioclimatic within cluster, well their pattern. Lastly, third ordination, integrating spatial patterns, has allowed differentiation at both national bioregional scales. Specifically, seven earmarked eradication action, six monitoring while remaining deemed suitable containment. Our results methodology meet demand new early warning tools; predict location outbreaks, establish monitor species.

Plant distribution and conservation in mediterranean islands’ lentic wetlands: there is more than aquatic species

Biodiversity and Conservation, Journal Year: 2024, Volume and Issue: 33(4), P. 1373 - 1392

Published: Feb. 7, 2024

Abstract This study investigates the distribution and conservation status of plant species in lentic wetlands Mediterranean islands. Field data on vascular macrophytes were collected from online national databases “Conservation island Basin” (MedIsWet). A comprehensive inventory was conducted, information main anthropogenic impacts priorities compiled. In addition to all hygro- hydrophytes, we retained those typically adapted environments with intermittent or temporary wetness. significant knowledge gap regarding found. lower endemism rate observed particularly coastal wetlands. However, approximately 25% species, mainly relatively wide distribution, identified as endangered unknown status. Including seasonal wetness is crucial when considering wetland efforts. The research emphasised importance diverse types, including permanent, natural artificial, for effective conservation. Artificial emerged potential habitats considerable biodiversity value. provides a valuable insights into ecology, relevance aquatic enhances our understanding biogeographic patterns processes, offers critical management wetlands, presents replicable approach that can be applied other contexts.

Invasive Traits of Symphyotrichum squamatum and S. ciliatum: Insights from Distribution Modeling, Reproductive Success, and Morpho-Structural Analysis

Biology, Journal Year: 2025, Volume and Issue: 14(1), P. 47 - 47

Published: Jan. 9, 2025

Understanding the drivers of invasive species' success is essential for predicting and managing their ecological impacts. Symphyotrichum squamatum, a South American species first recorded in Bucharest 2015, currently expanding into urban peri-urban areas Romania, raising concerns about its potential. This study provides comprehensive assessment invasiveness by integrating distribution modeling, reproductive trait analysis, morpho-structural evaluations. To deepen our understanding, we compare S. squamatum with ciliatum, already to identify shared traits potentially driving invasiveness. Using R software (version 4.3.0) bioclimatic variables, modeled potential both species. The was evaluated through germination tests on seeds from distinct Romanian populations, while anatomical analyses revealed adaptations linked Our findings indicate that shares successful invaders, as highlighted comparison ciliatum. However, expansion Romania appears be constrained environmental factors, continentality emerging key determinant influencing highlights importance combining modeling trait-based assess potential, offering robust framework alien

Dunes under attack: untangling the effects of landscape changes on Iceplant invasion (Carpobrotus spp., Aizoaceae) in Mediterranean coasts

NeoBiota, Journal Year: 2025, Volume and Issue: 98, P. 269 - 295

Published: April 30, 2025

Invasive alien plants (IAPs) are a great challenge for biodiversity conservation and management. Temporal landscape analysis has potential describing plant invasion process; however, solutions accounting of dynamics still limited. This research aims to explore the spatial-temporal pattern Carpobrotus spp. by analysing IAP expansion reduction processes in relation with changes on Mediterranean coastal dunes. Based detailed local land-cover maps years 2011 (T0) 2019–20 (T1), we described dune invaded areas using transition matrices identified reduction.

Coastal areas are biodiversity hotspots, providing essential ecosystem services, yet they among the most threatened systems, particularly by alien species invasion. The European regulation on invasive (IAS) highlights early detection as a key prerequisite for effective containment or eradication strategies. Traditional monitoring methods costly and time-consuming, Citizen Science (CS) may be promising alternative. We assessed contribution of generalist CS project “Wild Coast Adriatic” (WCA) developed iNaturalist platform to (AS) along Central Adriatic coast. Using WCA, we extracted occurrences explored AS seasonal patterns, geographic origins, dangers (EU regulation), distributions inside protected (Natura 2000 LTER sites).
