Research Journal of Ecology and Environmental Sciences <p>Research Journal of Ecology and Environmental Sciences(RJEES) is an openly accessible journal published monthly. The goal of this journal is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and perspectives in diverse areas of ecology &amp; environment and to keep a record of state-of-the-art research.</p> en-US (Robert Williams) (Robert Williams) Sat, 11 Nov 2023 00:00:00 +0000 OJS 60 New records for the alien vascular flora of Calabria (S-Italy) <p>While alien organisms, vascular plants included, are progressively increasing their worldwide impact on habitats, the present research confirms a similar dangerous trend for Calabria, the southernmost and floristically richest region of Italian Peninsula. The set of additional alien taxa here recorded for the vascular flora of Calabria includes: <em>Acacia melanoxylon</em>, <em>Bidens subalternans</em>, <em>Buddleja davidii</em>, <em>Cucurbita moschata</em>, <em>Cyclospermum leptophyllum</em>, <em>Erigeron annuus </em>subsp.<em> annuus</em>, <em>Hesperocyparis glabra, </em><em>Ligustrum ovalifolium</em>, <em>Mahonia aquifolium, Morus indica</em>, <em>Oenothera speciosa, </em><em>Prunus serotina</em>, <em>Pyracantha fortuneana</em>, <em>Rudbeckia laciniata, Solanum nitidibaccatum, Sparaxis bulbifera, Tradescantia cerinthoides, </em><em>Ulmus pumila</em>. These additional 18 taxa bring the total number of alien species from 382 to 400. The most represented biological forms are scapose therophyte and scapose phanerophyte with 5 species (27.8% of the total). The most frequent biogeographic origins of the surveyed species are North America (6 species; 33.3%), followed by Asia and South America both with 4 species (22.2%). The most common habitats hosting the recorded alien taxa are roadsides (8 species; 44.4%), although all surveyed plants have been found in deeply anthropized environments. The altitude of occurrence, extending 3 to 1,286 m a.s.l., together with other ecological data provided, demonstrate the ability of aliens to potentially colonize a wide range of environments in the region.</p> Alberto Capuano, Giuseppe Caruso Copyright (c) 2023 Research Journal of Ecology and Environmental Sciences Fri, 10 Nov 2023 00:00:00 +0000
