Abstract

In 2017, we investigated the population dynamics and flying activity of the south-east European endemic dragonfly species Cordulegaster heros Theischinger, 1979. This research was conducted in the southern part of Central Slovakia in the Revúcka vrchovina Upland at a submountainous stream called Drienok. The mark-release-recapture method was applied to study the population. Cordulegaster heros was observed 775 times during the midsummer season. We found out that the species has bimodal diurnal activity pattern with a highest peak from 17:00 until 19:00 hours, but the species had a short peak before noon as well. The differences between sexes in the sense of entering new individuals to the population were low during the main flying period. Estimated population size for males surpassed the population size of females. Probability of capture decreased by the end of the flying season without differences in sexes. This article is the first on the flying activity and population dynamics of Cordulegaster heros.

1979年，斯洛伐克的小腹蛛苍鹭的飞行活动和种群动态（昆虫纲：蜻蜓目：小腹蛛科）

2017年，我们调查了东南欧特有蜻蜓Cordulegaster heros Theischinger, 1979的种群动态和飞行活动。这项研究是在斯洛伐克中部的Revúcka vrchovina高地的一条名为Drienok的亚山溪流的南部进行的。采用标记-释放-再捕获法对种群进行研究。在仲夏季节，人们观察到了775次灯芯绒英雄。结果表明，该物种的日活动呈双峰型，在17:00 - 19:00时段达到高峰，但在中午之前也有一个短高峰。在主要飞行期，进入新个体的性别差异较小。估计雄性的种群规模超过了雌性。在飞行季节结束时，无性别差异的捕获概率下降。这篇文章是第一个关于Cordulegaster英雄的飞行活动和种群动态的文章。

期刊介绍： International Journal of Odonatology (IJO) is aimed at providing a publication outlet for the growing number of students of Odonata. It will address subjects such as the ecology, ethology, physiology, genetics, taxonomy, phylogeny and geographic distribution of species. Reviews will be by invitation, but authors who plan to write a review on a subject of interest to the journal are encouraged to contact the editor.
