Abstract

The distribution of butterflies was mapped throughout entire Estonia in 2016 and 2017. Butterflies were surveyed during three phenologically targeted visits at more than 1200 pre-selected sites. In total, over 180 000 individuals belonging to 97 species were recorded. We compare the resulting distribution maps with historical records, and discuss changes in the species' distribution. We conclude that, within the time frame of century, the changes in the Estonian butterfly fauna were moderate. For about 75% of species, there was no conclusive evidence of a change in distribution or abundance. In case of the remaining 25%, there were more butterfly species with an increasing rather than a decreasing trend in abundance and/or distribution. Some but not all of those changes could be associated with ongoing climate change. The decline of several dry-meadow specialists can be regarded as the most urgent conservation concern.

爱沙尼亚蝴蝶（鳞翅目：蝶形目）的分布：一项系统测绘项目的结果揭示了长期趋势

2016年和2017年绘制了整个爱沙尼亚的蝴蝶分布图。在1200多个预先选定的地点进行了三次以酚类物质为目标的访问，对蝴蝶进行了调查。总共记录了97个物种的18万多个个体。我们将由此产生的分布图与历史记录进行比较，并讨论物种分布的变化。我们得出的结论是，在本世纪的时间框架内，爱沙尼亚蝴蝶种群的变化是适度的。对于大约75%的物种，没有确凿的证据表明分布或丰度发生了变化。在剩下的25%的情况下，蝴蝶物种的数量和/或分布呈增加而非减少的趋势。其中一些但并非全部的变化可能与持续的气候变化有关。几位干旱草地专家的减少可以被视为最紧迫的保护问题。

期刊介绍： Annales Zoologici Fennici publishes mainly original research reports, but also in-depth reviews and commentaries on all aspects of animal ecology and evolution, and fields related to them. Our aim is to promote papers which focus on the interactions among various components in the past and present environments by using integrative and cross-disciplinary approaches. This may be achieved by employing tools from different fields of research, such as (but not restricted to): ecology and paleoecology, molecular ecology and phylogeography, conservation biology, human-induced contemporary evolution and wildlife management, animal behaviour and interactions (including recognition systems and mechanisms), paleontology (except systematics and taxonomy) and evolution, bioenergetics.
