Recent research in island biogeography has highlighted the important role of late Quaternary sea-level fluctuations in shaping biogeographic patterns in insular systems but focused on oceanic systems. Through this study, we aim investigate how late Quaternary sea-level fluctuations shaped species richness patterns in continental-shelf island systems. Focusing on the Aegean archipelago, we first compiled maps of the area\&$\#$39;s geography using published data, under three sea-level stands: (a) current; (b) median sea-level over the last nine glacial\–interglacial cycles (MSL); and (c) Last Glacial Maximum (LGM). We gathered taxon\–island occurrences for multiple chorotypes of angiosperms, butterflies, centipedes, and reptiles. We investigated the impact of present-day and past geographic settings on chorological groups by analyzing island species\–area relationships (ISARs) and using generalized linear mixed models (GLMMs) selection based on multiple metrics of goodness of fit. Our results confirm that the Aegean\&$\#$39;s geography has changed dramatically since the LGM, whereas the MSL only modestly differs from the present configuration. Apart for centipedes, paleogeographic changes affected both native and endemic species diversity through altering connections between land-bridge islands and the mainland. On land-bridge islands, we detected over-representation of native species and under-representation of endemics. Unlike oceanic islands, sea-level-driven increase of isolation and area contraction did not strongly shape patterns of species richness. Furthermore, the LGM configurations rather than the MSL configuration shaped patterns of endemic species richness. This suggests that even short episodes of increased connectivity with continental populations are sufficient to counteract the genetic differentiation of insular populations. On the other hand, the over-representation of native nonendemic species on land-bridge islands reflected MSL rather than LGM mainland connections. Our study shows that in terms of processes affecting species richness patterns, continental archipelagos differ fundamentally from oceanic systems because episodic connections with the mainland have profound effects on the biota of land-bridge islands.

In the year 2014, succession of plants, spiders and other invertebrates was studied in the middle and on the border of the quarry as well as on the rocks. Sites with dense and sparse vegetation cover were examined in the first two biotopes. In total, 77 plant, 102 spider, seven diplopod, three isopod, two harvestman and two pseudoscorpion species were found. Among the spider species, 20 of them were newly discovered in the quarry and 21 of them were of significant ecological importance. This number confirms that limestone quarries are important as a refuge for rare species whose habitats are disappearing from our country. The most important finding, beside that of Pardosa wagleri, is Pseudomaro aenigmaticus. In the case of the latter species, it is the third record in the Czech Republic.

In 2013, population density of critically endangered wolf spider Pardosa wagleri was charted and two localities at the northern parts of the quarry of {\v C}ertovy schody \– West was investigated. Population of P. wagleri is relatively rich and occurs along the whole western, north-western and south-western margin of the bottom of the quarry. The spiders inhabit namely moist cavities under stones. A humid depression hosts an indifferent arachnofauna. Thus, a small lake planned at this place will not negatively affect the spider population. In addition, biodiversity will be enriched by hygrophilous species. Despite rare and endangered species are currently present, technical reclamation is wasting of natural potential because these rare and endangered species have no chance to survive. Therefore, natural succession has to be preferred to technical reclamation. This approach will result in development of mosaic landscape with sparse vegetation. Technical reclamation (namely planting coniferous monocultures) is disadvantageous due to its high costs and because it decreases biodiversity.
