The paper presents new records for 18 vascular plant species from six Eurasian countries. Three taxa (Lepidium densiflorum, Stipa czerepanovii, Xanthium albinum) are reported from Kazakhstan, one (Ranunculus schmakovii) from Mongolia, three (Dianthus campestris, Ranunculus kauffmannii, Viola suavis) from Poland, five (Eragrostis amurensis, Linum catharticum, Ludwigia peploides subsp. stipulacea, Pyrethrum mikeschinii, Solidago canadensis) from Tajikistan, five (Clinopodium menthifolium, Juncus effusus, Mollugo cerviana, Poa sphondylodes, Vulpia myuros) from Russia, and one (Orobanche alba subsp. xanthostigma) from Georgia. Ten of the taxa presented (Clinopodium menthifolium, Dianthus campes…

Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 8

The paper presents new records of 24 vascular plant species from 11 Eurasian countries. One taxon (Orobanche laxissima) is reported from Armenia ; one (Epipactis condensata) from Azerbaijan ; two (Phragmites americanus, Polygala multicaulis) from Belarus ; one (Stipa caucasica) from Egypt ; one (Puccinellia hauptiana) from Kyrgyzstan ; three (Aquilegia xinjiangensis, Geranium saxatile, Ranunculus songaricus) from Mongolia ; one (Stipa roborowskyi) from Pakistan ; three (Echinochloa muricata, Erigeron acris subsp. podolicus, Hypericum majus) from Poland ; six from Russia, whereof one (Zanthoxylum armatum) from the European part of Russia and five (Chaerophyllum aureum, Elsholtzia densa, Poa …

Czy Nysius huttoni (Hemiptera: Heteroptera: Lygaeidae), gatunek obcy dla Europy, może mieć w Polsce sprzyjające warunki do bytowania?

2020

Nysius huttoni, the species endemic to New Zealand, is regarded as a pest which feeding can seriously reduce crop establishment in forage brassicas. It was discovered for the first time in Europe in 2002 (the Netherlands) and has spread in several European countries (Belgium, France, United Kingdom, Germany). Although detailed data on the natural spread of N. huttoni is lacking, it can theoretically be transported over long distances with infested plants, and is often found on apple and kiwi fruit packages exported from New Zealand. The species was hitherto not reported from Poland, therefore its potential geographic distribution was modelled using maximum entropy (Max-Ent) in order to pred…

Fungi related to larvae of red palm weevil Rhynchophorous ferrugineus (Coleoptera: Curculionidae)

2010

As a first step to developing effective biocontrol strategies, we analyzed the pathogens and mainly the entomopathogenic fungal species, present into dead larvae of Rhynchophorous ferrugineus; a quarantine pest recently introduced and acclimated in Sicily (Italy). From 2008 to 2010, we estimated the natural larval mortality (> second instar) of R. ferrugineus collected from infested palm Phoenix canariensis; that was variable from 10 to 35%, according to the different seasons Among the different pathogens recorded the fungi seems have an important role, than in order to distinguish saprophytic or opportunistic species from potential pathogens (including the non cultivable ones) we applied d…

How do non-indigenous species affect native species and habitats?

Biological invasions are a key driver of global change, affecting biodiversity and natural ecosystem functioning. Non-indigenous species (NIS) with significant established and expanding populations have the potential to become invasive, with serious environmental, socio-economic, and/or human health consequences. Mediterranean Islands (including Marine Protected Areas “MPAs”), important hotspots of biodiversity, are particularly vulnerable to NIS invasions. Understanding the effects of NIS species on biodiversity, as well as their current distribution and expansion trends, is therefore critical for creating effective conservation strategies. Here, we present three different case studies fro…

Ocena możliwości potencjalnej ekspansji prześwietlika dębowego Corythucha arcuata (Say, 1832), inwazyjnego gatunku z rodziny Tingidae (Hemiptera: Het…

2020

Corythucha arcuata, the North American oak lace bug feeding on leaves of “white oaks” in its native range, was discovered in Europe in 2000 (in northern Italy). Since that time it has spread rapidly in several European countries where its population outbreaks have been observed. However, the species was not reported from Poland, so far. In this study the potential geographic distribution of Corythucha arcuata was modelled using maximum entropy (Max-Ent) in order to predict the regions of Poland where it would have found the best environmental conditions for its further spread. The results showed that the highest habitat suitability areas were located in the central-eastern parts…

L'espansione delle specie legnose esotiche negli habitat naturali e seminaturali: un problema di gestione forestale attuale

2018

Le specie esotiche invasive si diffondono soprattutto in aree antropizzate, dove riescono ad occupare spazi lasciati liberi dalle specie autoctone e dalle comunità da esse edificate. In questi ultimi anni, tuttavia, numerose specie arboree ed arbustive esotiche si stanno diffondendo in Italia, oltre che in ambienti disturbati, anche in aree naturali e semi-naturali. È questo il caso dell’ailanto (Ailanthus altissima (Mill.) Swingle), una delle specie arboree esotiche invasive più diffuse e dannose negli ecosistemi forestali temperati e mediterranei di tutto il mondo. Dal punto di vista ecologico, l’ailanto mostra tutti i caratteri tipici delle specie pioniere arboree: rapido accrescimento i…

Forest nurseries and the National Recovery and Resilience Plan: the case of Sicily and Apulia (Italy)

2023

In Italy, the National Recovery and Resilience Plan (NRRP) foresees the planting of ca. 6.6 million trees to establish urban and peri-urban forests in 14 metropolitan cities. This ambitious project requires a significant number of native trees and shrubs, currently unavailable in Italian public and private nurseries. This survey analyzes the state of forest nurseries in two administrative regions of southern Italy, i.e. the “Filici” forest nursery (province of Agrigento, Sicily) and the Gargano Mountain Reclamation Consortium (province of Foggia, Apulia), to evaluate the adequacy of Sicilian and Apulian forest nurseries as potential sources of plant material to meet the requirements of the …
