Abstract

In 1990–2020, long-term field observations in the Transbaikal region (Siberia, Russia) revealed a range expansion of the nemoral butterfly species Limenitis sydyi (Lepidoptera, Nymphalidae) further into Siberia (120° E to 110° E). This species had not been registered to the west of the Chita–Kyra longitudinal line (112° E) before the 2000s, but subsequently became rather common in the environs of the city of Chita. Its first occurrence in the Republic of Buryatia (110° E) was recorded in 2012. This species prefers the sparse-growth forests dominated by larch (Larix sp.) and birch (Betula pendula Roth) that commonly occur in the second-order river valleys at elevations of 400–600 m, whereas the broader and narrower river valleys are only marginally suitable for this nemoral species. Additionally, rather high air humidity levels are critical to L. sydyi during particular periods of its life cycle (May–June and September), as well as a snow depth of at least 10–20 cm.

鳞翅目蛱蝶科）在外贝加尔地区扩展的原因

摘要 1990-2020 年间，在外贝加尔地区（俄罗斯西伯利亚）进行的长期实地观察发现，蛱蝶物种 Limenitis sydyi（鳞翅目，蛱蝶科）的分布范围进一步扩展到西伯利亚（东经 120° 至东经 110°）。在 2000 年代之前，赤塔-凯拉纵线（东经 112°）以西地区还没有记录到该物种，但后来在赤塔市周边地区变得相当常见。该物种首次出现在布里亚特共和国（东经110°）是在2012年。该物种喜欢生长在海拔 400-600 米的二阶河谷中以落叶松和桦树为主的稀疏森林中，而较宽和较窄的河谷则不太适合该物种生长。此外，在 L. sydyi 生命周期的特定时期（5-6 月和 9 月），相当高的空气湿度以及至少 10-20 厘米的积雪深度对其至关重要。

期刊介绍： Russian Journal of Biological Invasions publishes original scientific papers dealing with biological invasions of alien species in both terrestrial and aquatic ecosystems and covers the following subjects:description of invasion process (theory, modeling, results of observations and experiments): invasion corridors, invasion vectors, invader species adaptations, vulnerability of aboriginal ecosystems;monitoring of invasion process (reports about findings of organisms out of the limits of natural range, propagule pressure assessment, settling dynamics, rates of naturalization);invasion risk assessment; genetic, evolutional, and ecological consequences of biological invasions of alien species; methods, means of hoarding, processing and presentation of applied research data (new developments, modeling, research results, databases) with factual and geoinformation system applications;use of the results of biological invasion research (methods and new basic results) under the study of marine, fresh-water and terrestrial species, populations, communities and ecosystems; control, rational use and eradication of the harmful alien species..
