Findings in Ecology Research Reported from University of Osnabrueck (Vegetation and climate determine ant-mound occupancy by a declining herbivorous insect in grasslands)
By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Current study results on Ecology Research have been published. According to news reporting originating in Osnabruck, Germany, by VerticalNews journalists, research stated, "There is considerable research on the effects of soil-disturbing ecosystem engineers in semi-natural Central European grasslands in terms of plant species diversity, soil properties and soil microorganisms. However, knowledge on the importance of such ecosystem engineers for animal diversity is still relatively rare."
The news reporters obtained a quote from the research from the University of Osnabrueck, "In this study we analyse the role of Lasius flavus nest mounds as habitats for larvae of the declining burnet moth species zygaena purpuralis in calcareous grasslands. We assumed that anthills act as preferred larval habitats in dependence on climate or vegetation structure. The analysis considers a macroclimatic gradient by comparing sites with differing elevation and, hence, local climates. Additionally, we analysed the importance of anthills for Z. purpuralis along a microclimatic gradient by comparing sites with different vegetation structures. The study clearly shows that anthills are important larval habitats when general microclimatic conditions in the grasslands are unfavourable due to a cool climate at higher elevation or dense vegetation. The likelihood of detecting larvae of the burnet moth species on sites where anthills were occupied was higher on the mounds than within the surrounding vegetation. Anthills were preferred as larval habitats by Z. purpuralis as they combine two essential elements for successful larval development: (i) a favourable microclimate thanks to an open vegetation structure and (ii) a sufficient amount of food."
According to the news reporters, the research concluded: "The study underlines the importance of L. flavus as an ecosystem engineer for maintaining habitat heterogeneity and biodiversity within semi-natural grasslands."
