“…In particular, post-mining sites, which are typically highly degraded or even destroyed, represent habitats where succession starts on bare substrate. Conservation potential of post-industrial sites was already demonstrated for butterflies (Beneš et al 2003;Turner et al 2009;Lenda et al 2012), dragonflies (Harabiš and Dolný 2012), spiders (Wheater et al 2000), certain beetle species (Eyre et al 2003;Warren and Büttner 2008;Boukal 2010;Topp et al 2010), ants (Ottonetti et al 2004(Ottonetti et al , 2006, and the aquatic invertebrates (Dumnicka and Galas 2006). Contrary to that, post-industrial sites were found to be only slowly colonized by taxa with low migration ability such as nematodes (Háněl 2004(Háněl , 2008, and are considered as potentially deleterious (mostly due to the presence of residual contaminants) for the taxa migrating from the surrounding landscape unaffected by the industrial activities (Lefcort et al 2010;.…”

Evidence-based conservation allows the evaluation of both the collateral benefits and the drawbacks of a wide range of human activities, like quarrying. In this study, the community structure of bees and wasps (Hymenoptera:Apocrita) in Central European sandpits was investigated, focusing on the changes caused by quarrying cessation and technical reclamation, as well as on the changes caused by spontaneous succession leading to the increased availability of food resources but also to the loss of the number and size of available bare sand patches. The bees and wasps demonstrated an exceptional ability to colonize the newly emerging sand quarrying areas, and to survive in them unless these were quarried as intensively as to not allow the development of any early successional vegetation. Both active and closed sandpits were found to serve as important regional refuges for the persistence of many rare species. In total, 221 species were detected, 53 of those were red-listed, with two species thought to be regionally extinct. Typically, active quarrying was associated with the presence of Bembecinus tridens, Halictus subauratus, H. maculatus, and Andrena nigroaenea. The list of the species of conservation interest is provided, and so is the detailed analysis of the life-history traits of the species in relation to the presence of bare sand patches, vegetation cover, quarrying intensity, and time elapsed since the formation of each artificial habitat patch. Sandpits as refuges for xerothermophilous and psammophilous hymenopterans are usually completely and irreversibly lost if the current legislature enforcing the technical reclamation over spontaneous or assisted succession is applied in all or most of the post-mining areas.

“…Morphological differences between species of tiger beetles are apparently affected by selection for specific habitat requirements (Cardoso & Vogler 2005). Therefore, the discovery of tiger beetles in the Tiger beetles are predatory insects that prefer riverine habitats with sandy soils and minimal vegetation, where periodic disturbance by wind and water removes encroaching vegetation (Warren & Buttner 2008). Female tiger beetles are specific in choosing oviposition sites, as larval stages are soil dwelling and spend their entire life in the same location (Brust et al 2006).…”

Abstract:The reservoir ecosystems of Sri Lanka are ancient man-made riparian habitats. Adequate food supply and suitable climatic and soil parameters make these habitats ideal for tiger beetles. Twenty-six reservoirs were investigated for the presence of tiger beetles, and four species were recorded: Calomera angulata (Fabricius, 1798), Myriochila (Monelica) fastidiosa (Dejean, 1825), Cylindera (Oligoma) lacunosa (Putzeys, 1875) and Lophyra (Lophyra) catena (Fabricius, 1775). Calomera angulata is the most common species, occurring in the majority of reservoir habitats. Key environmental factors of climate and soil were examined and linked to habitat preferences of tiger beetle species.

“…There are several other studies which highlight the importance of small-scale soil disturbance for the conservation of rare and endangered species (e.g. Fleischer et al 2013;Gröning et al 2007;Tschöpe and Tielbörger 2010;Warren and Büttner 2008). Within mesotrophic grasslands where bare ground is usually rare, mound-building ecosystem engineers, such as T. europaea, play an important role for L. phlaeas.…”

“…Furthermore, such sites act as important microhabitats for disturbance-dependent invertebrate species (e.g. Gröning et al 2007;Warren and Büttner 2008;Wünsch et al 2012). Many butterfly species require a specific vegetation structure as they are dependent on certain microclimatic conditions for larval development (García-Barros and Fartmann 2009).…”

Both land use intensification and abandonment within grasslands lead to a homogenisation of vegetation structure. Therefore, specially structured microsites such as vegetation gaps with bare ground play an important role for species conservation within grasslands. Vegetation gaps are crucial for the establishment of low-competitive plant species and offer special microclimatic conditions essential for the development of the immature stages of many invertebrate species. The influence of small-scale soil disturbance in the form of mounds created by ecosystem engineers such as ants or moles on biodiversity is therefore of special scientific concern. The effects of mound-building species on plant species diversity have been extensively studied. However, knowledge on the significance of these species for the conservation of other animals is rare. In this study we analyse the importance of mounds created by the European mole (Talpa europaea) as an oviposition habitat for the small copper (Lycaena phlaeas) within Central European mesotrophic grasslands. Our study showed that host plants occurring at molehills were preferred for oviposition. Oviposition sites were characterised by an open vegetation structure with a high proportion of bare ground (with a mean coverage of about 50 %), a low cover of herbs and low-growing vegetation (mean height: 4.5 cm). Our study clearly illustrates the importance of small-scale soil disturbance for immature stages of L. phlaeas and the conservation of this species within mesotrophic grasslands. Mound-building ecosystem engineers, such as T. europaea, act as important substitutes for missing dynamics within mesotrophic grasslands by diversifying vegetation structure and creating small patches of bare soil.
