“…since the vast majority of recorded species preferred microhabitats where all these variables were present. As suggested earlier by Potts et al (2005) and Cruz-Sánchez et al (2011) for the burnt areas, the community structure and relative abundances of bees and wasps was driven by the variation in availability of suitable resources, highlighting the availability of bare soil, the abundance of stemmed plants and the presence of pre-existing cavities. Active sandpits are important for those species, which build their nests entirely or mostly in loose sand, e.g., Bembecinus tridens, Alysson spinosus and Andrena barbilabris of the numerous species, and certainly for many very rare species found only in one or several specimens (e.g., genus Oxybelus).…”

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.

Forest fire remains among the most controversial topics in nature conservation. Here, we address changes in abundance and species composition of the bee and wasp community following a temperate forest crown fire that led to nearly complete defoliation and dieback of trees within 2 years. We found a highly dynamic community of 252 bee and wasp species (representing 18.8 % of total bee and wasp species known from the Czech Republic) that utilized 1-7-year-old burned forest stands. Species richness in the burned forest stands was significantly higher than that recorded in nearby forest that had been unaffected by any recent fire. The unburned forest hosted only 88 species. We found 42 red-listed species, of which 40 were present in the burned forest, while only 12 were present in the control forest. Numerous early-and late-responding species were detected, but maximum species diversity was reached 3 years after the fire. Only 7 of the total of 261 species were limited to the forest that was unaffected by any recent fire. A management regime that supported the presence of bare sand and heather patches, and removal of all but solitary pine trees, was found to be insufficient to support the full spectrum of forest fire-dependent species. This was mainly due to the absence of charred or decaying dead wood, which is otherwise utilized by numerous redlisted cavity adopters that are absent in the surrounding cultural landscape. Retaining part of the charred trunks is suggested as a novel post-fire conservation measure.

“…Numerous studies have addressed the biotic variables, such as floral diversity (Tepedino and Stanton 1981;Gathmann et al 1994;Taki et al 2008), floral abundance (Banaszak 1996), availability of pollen and nectar resources (Petanidou and Vokou 1990;Polidori et al 2010a), changes in availability of the preferred prey (O'Neill 2001;Polidori et al 2007;Polidori et al 2010b), or more of these driving factors combined (Potts et al 2003a(Potts et al , 2005. Several indirect modifiers were also identified, these include changing land use practices including agricultural intensification (Banaszak 1995), habitat fragmentation or isolation (Jennersten 1988;Steffan-Dewenter and Tscharntke 1999), grazing (Potts et al 2003a), gardening (Gotlieb et al 2011, fire (Lockwood et al 1996;Potts et al 2001Potts et al , 2003bPotts et al , 2005Campbell et al 2007;Cruz-Sánchez et al 2011), disease and parasite spread (Polidori et al 2010c, d), climate change (Dejean et al 2010;Klapwijk et al 2010;Tryjanowski et al 2010), introduction of nonnative species (Wilson and Holway 2010;Kraus et al 2011), and competition of solitary bees with managed pollinators (Paini and Roberts 2005;Kondo et al 2009;Nagamitsu et al 2010;Tsuchida et al 2010).…”

Microhabitat selection based on abiotic factors was examined in five species of digger wasps (Sphex funerarius, Ammophila heydeni, Ammophila pubescens, Ammophila sabulosa, Bembix tarsata), four of which are of high conservation interest. All the study sites were located in areas affected by anthropogenic disturbance (reclaimed brown-coal mining areas, and railway dykes) in Central Europe. The individual species responded differentially to the variability in each of the physical characteristics measured, which resulted in site-specific exclusion of individual sphecid species. The sphecids were found to discriminate between available microhabitats based on ground inclination (slope) and vegetation cover. All but A. heydeni segregated the microhabitats according to the content of gravel and sand particles. S. funerarius and B. tarsata were limited by their preferences of low soil compactness, whereas A. pubescens utilized highly compacted soils, which were predominant in the study area. Soil shear strength (cohesiveness) was driving the level of gregariousness of the sphecids. In B. tarsata, number of cells per burrow was found to be higher in soils with increased penetration resistance. Experimental increase in soil compactness led to the abandonment of nesting microhabitats in the subsequent nesting seasons. Besides the well-known biotic factors, such as specialization at different size or type of prey, variability in abiotic factors between individual microhabitats (e.g. patches of sand) was found to be both necessary and sufficient to allow the parallel presence of viable populations of several sphecid species.
