Abstract

Abstract The reliance on visual cues can vary among ant species living in different habitats, and is mostly influenced by the level of ambient illumination and the morphological adaptations of ant species that can determine their period of daily activity. Thus, different illumination regimes might affect ant community composition in habitats with different ambient illumination intensities. Despite this, in the literature, information is scarce about the effects of ambient illumination on ant activity. In the present study, we investigated the effect of ambient illumination intensity on the activity of ant species and their community composition under herbaceous and woody plants in 24 localities from Kyiv and Kyiv region, Ukraine. Our results showed that the ambient illumination properties of the habitat type affect the presence of ant species and the activity of their workers. In open habitats, the maximum ambient illumination had a negative effect, whereas in closed, woody habitats the maximum ambient illumination and tree circumference generally had a positive effect on the number of non-dendrobiotic ant individuals found on individual plants. The dendrobiotic species were less affected by the maximum illumination intensity. Although, in closed habitats, the effect of the previous variables and their interaction had species-specific aspects. Based on the former, we can tell that more structured forest habitats can provide broader illumination intensity ranges, allowing more ant species to coexist. However, similar illumination intensity ranges can lead to overlaps in the activity of ant species under the same illumination conditions, especially in open habitats. The outcomes of these interactions are highly influenced by larger trees that besides lowering illumination intensities, can enhance ant worker activity and promote species coexistence.

光照制度对城市生境中膜翅目蚁(蚁科)群落结构的影响

生活在不同栖息地的蚂蚁对视觉线索的依赖程度各不相同，主要受环境光照水平和形态适应的影响，这些因素决定了蚂蚁的日常活动周期。因此，不同的光照制度可能会影响不同环境光照强度生境中蚂蚁群落的组成。尽管如此，在文献中，关于环境光照对蚂蚁活动的影响的信息很少。在乌克兰基辅和基辅地区的24个地点，研究了环境光照强度对草本植物和木本植物下蚂蚁物种活动及其群落组成的影响。结果表明，生境类型的环境光照特性影响蚁种的存在和工蚁的活动。在开放生境中，最大环境照度对非树栖蚂蚁个体数量有负面影响，而在封闭的木本生境中，最大环境照度和树周长对单株上发现的非树栖蚂蚁个体数量有积极影响。最大光照强度对树栖生物的影响较小。然而，在封闭生境中，上述变量及其相互作用的影响具有物种特异性。基于前者，我们可以知道，更结构化的森林栖息地可以提供更广泛的照明强度范围，允许更多的蚂蚁物种共存。然而，在相同的光照条件下，相似的光照强度范围会导致蚁种的活动重叠，特别是在开阔的栖息地。这些相互作用的结果受到大树的高度影响，大树除了降低光照强度外，还可以增强工蚁的活动，促进物种共存。

期刊介绍： Insectes Sociaux (IS) is the journal of the International Union for the Study of Social Insects (IUSSI). It covers the various aspects of the biology and evolution of social insects and other presocial arthropods; these include ecology, ethology, morphology, population genetics, reproduction, communication, sociobiology, caste differentiation and social parasitism. The journal publishes original research papers and reviews, as well as short communications. An international editorial board of eminent specialists attests to the high quality of Insectes Sociaux, a forum for all scientists and readers interested in the study of social insects.
