Freshwater ecosystems are among the most susceptible to biological invasions. The South American Ludwigia hexapetala is an aquatic plant that becoming increasing threat in many European waterbodies, recently including Italy. This study aimed define main parameters influencing early colonization stage of L. by overlapping percentage cover this species with environmental parameter data collected at 24 sites from six waterbodies north-central At each site, chemical and physical characteristics water (temperature, pH, dissolved oxygen, conductivity, nitrates, phosphates, ammonia, depth, transparency), grain size substrate level anthropogenic disturbance were evaluated. results showed although prefers shallow, warm, alkaline, moderately rich ions nutrients (especially phosphates) oxygen-poor waters, it can grow a wide range conditions. Moreover, as typical invasive alien species, spreads opportunistically disturbed, unstable sites. Thus, invade freshwater habitats different conditions subjected disturbance. However, suggest depth may be limiting factor which does not seem able colonise waters deeper than 1 m investigated sites, while has been observed significantly other countries longer invasion history. Detecting influence growth becomes crucial both identify at-risk initiate timely monitoring actions for develop better management control have already invaded.

Knowledge on alien species is needed nowadays to protect natural habitats and prevent ecological damage. The presence of new plant in Italy increasing every day. Calabria, its southernmost region, not yet well known with regard this aspect. Thanks fieldwork, sampling, observing many exotic plants here, we report data 34 taxa. In particular, found three taxa for Europe (Cascabela thevetia, Ipomoea setosa subsp. pavonii, Tecoma stans), (Brugmansia aurea, Narcissus ‘Cotinga’, ‘Erlicheer’), one the Italian Peninsula (Luffa aegyptiaca), 21 Calabria (Allium cepa, Asparagus setaceus, Bassia scoparia, Beta vulgaris vulgaris, Bidens formosa, Casuarina equisetifolia, Cedrus atlantica, Chlorophytum comosum, Cucurbita maxima maxima, Dolichandra unguis-cati, Fagopyrum esculentum, Freesia alba, Juglans regia, Kalanchoë delagoënsis, Passiflora caerulea, Portulaca grandiflora, Prunus armeniaca, dulcis, Solanum tuberosum, Tradescantia sillamontana, Washingtonia filifera). Furthermore, provide first geolocalized record Araujia sericifera, confirmation Oxalis stricta, propose a change status four (Cenchrus Salpichroa origanifolia, Sesbania punicea, Nothoscordum gracile) Calabria. updated knowledge could allow prevention other entries eliminate potential threat habitats.

High-elevation mountain communities are progressively threatened by habitat fragmentation and climate change resulting in shift biodiversity loss. Despite it, very few studies have focussed on niche distribution diversity pattern of non-native native plant species high communities, their role identifying endemic with extinction risk Himalayas. To determine width based the nativity, ascertain conservation prioritization endemic/native species, four sites were selected western We analysed indices (based native, non-native, total species) such as Species richness, Simpson index, Chao-1 Whittaker index (βw), across elevational gradient study sites. Non-native found to thrive lower elevations. The declined increase elevation, but a had broad (habitat generalist). Such generalist may lead displacement or specialist (having narrow width). like Aconitum heterophyllum, violaceum, Bergenia stracheyi, Dactylorhiza hatagirea, Jurinea dolomiaea, Sinopodophyllum hexandrum, Morina longifolia, Roscoea alpina etc. width. will face an due upward species. more susceptible accelerated spread influenced change. This emphasizes crucial need implement strategies for control describing compositional changes at higher elevations, aids efficiently identify conserve under risk.

The first inventory of casual and naturalised alien plants Kyrgyzstan is based on an overview published data, which were re-assessed re-evaluated using modern standards. Altogether, 151 species registered in the country, nearly 40% became naturalised. total number plant proportion aliens are relatively low due to harsh climatic conditions (high aridity continentality) predominantly high elevations. highest originated from Mediterranean, can be explained by some common features between this area Central Asia, but half ten most harmful Americas. intensity invasions was greatest during period Russian Empire USSR, rapid accumulation continues independent Kyrgyzstan. uneven distribution different elevations across its regions, as well concentration agricultural activities human population along warm lowland depressions.

Further research can clarify whether round due confusion recently introduced cryptic new genotype, post-introduction evolution, or just increased scientific interest biological invasions.

In this paper, based on fieldwork and herbaria surveys, new data concerning the presence of 32 native alien vascular species for Sicily (Italy) are provided. Among species, occurrence following taxa is reported first time or confirmed after many decades non-observation: Aira multiculmis, Arum maculatum, Carex flacca subsp. flacca, Mentha longifolia, Oxybasis chenopodioides, Najas minor Xiphion junceum. Furthermore, we document three (Cornus mas, Juncus foliosus Limonium avei) that, despite being repeatedly observed in literature, inexplicably omitted by most recent authoritative checklists regarding flora Italy. Finally, fifteen to (including one Europe, i.e., Pyrus betulifolia) seven poorly documented allochthonous island, two them, a status change proposed. These records allow us better define European national distribution targeted offer insights Sicily.
