Abstract

Abstract: Recent reports of Najas marina L. (Hydrocharitaceae) from Sicily have been interpreted as a confirmation of its presence on the island, where it was earlier mentioned in the 1800s. However the recent finds do not represent “N. marina” (currently N. major All.) but N. marina subsp. armata Horn (= N. delilei Rouy), a different taxon, previously not recorded from Sicily. According to those reports and several new finds presented here, it appears to be invading reservoirs and lakes in southern Sicily and seems to be naturally expanding its range. Climate change is suggested as possible cause of this shift. The same trend appears to be taking place across the whole N Mediterranean area, from Portugal to Cyprus. The old Sicilian record of “N. marina” (i.e. N. major) remains unconfirmed: the only site where it was collected was completely destroyed to make space for houses and touristic exploitation.

Najas marina subsp。地中海地区的armata（水藻科）：气候变化的影响？

摘要：最近关于西西里岛的Najas marina L.（水藻科）的报道被解释为证实了它在该岛的存在，19世纪就有人提到过它。然而，最近的发现并不代表“N.marina”（目前为N.majorAll.），而是N.marina亚种。armata Horn（=N.delilei Rouy），一个不同的分类单元，以前没有从西西里岛记录。根据这些报告和这里的几项新发现，它似乎正在入侵西西里岛南部的水库和湖泊，并且似乎正在自然地扩大其范围。气候变化被认为是这种转变的可能原因。从葡萄牙到塞浦路斯，整个地中海北部地区似乎也出现了同样的趋势。西西里岛关于“N.marina”（即N.major）的旧记录尚未得到证实：唯一收集它的遗址被完全摧毁，为房屋和旅游开发腾出空间。引文：Troia A.2022：Najas marina subsp。地中海地区的armata（水藻科）：气候变化的影响Willdenowia 52：91–101。该记录的版本于2022年4月5日首次在线发布，随后将收录在2022年4月刊中。

期刊介绍： Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
