“…According to our ndings, we conclude that active conservation management strategies are essential to preserve and maintain the post-re early-successional beetle assemblages in locales where these species are found. Wild res play a pivotal role in psammophilous assemblages by creating favorable environmental conditions (Toman 1988). Therefore, increasing forest canopy closure in these habitats should not be viewed simply as regeneration or a return to a natural state, but rather as a potential threat to their richness and diversity.…”

Psammophilous beetles, a group endangered in temperate ecosystems, are mainly threatened by habitat loss. These beetles thrive in areas formed by the weathering of marine or fluvial sediments. Historically, practices such as slash-and-burn method or litter raking have exposed and destabilized sediments. In Europe, the Scots pine (Pinus sylvestris) has been used to stabilize sand dunes, improve soil composition and create shadier environments. This has led to the degradation of psammophilous communities and a decline in biodiversity. Our study examines whether fire can help restore and maintain psammophilous beetle populations. Our research focused on two aspects: (i) the long-term effects of wildfire in 2012 on beetles (Coleoptera: Carabidae) in the "Moravská Sahara–Bzenec district" of South Moravia (period 2013–2021), and (ii) the effects of environmental factors, influenced by the aforementioned wildfire on the distribution of these beetles in the period 2016 to 2021. The study compared species composition, life-history traits, and functional diversity between three forest stages: (i) newly disturbed areas with Coarse Wood Debris (CWD) left to naturally decay; (ii) semi-decayed mid-aged stands and (iii) reference mid-aged stands. Our findings indicate that fire was important factor influencing species assemblages. Interestingly, post-fire changes in food availability emerged as the second important factor, leading to the formation of two distinct species clusters: granivorous species thrived on site dominated by graminoids, and site with accumulated CWD was attracted predominantly by carnivorous species. We propose, that fire management could be an effective strategy for conserving and promoting the diversity of psammophilic beetles.

“…We suggest that re management is an effective strategy for conserving and enhancing the functional diversity of post-re beetle assemblages in areas where these species exist (Toman 1988). We recommend employing a combination of repeated prescribed burning (Hamřík and Košulič 2021) and slash-and-burn techniques (Koivula and Vanha-Majamaa 2020), avoiding the vegetation season in order to preserve early-successional re-colonizers (Wiesbauer 2007;Götmark 2013;Kędzior et al 2020).…”

Psammophilous beetles, a group endangered in temperate ecosystems, are mainly threatened by habitat loss. These beetles thrive in areas formed by the weathering of marine or fluvial sediments. Historically, practices such as slash-and-burn method or litter raking have exposed and destabilized sediments. In Central Europe, the Scots pine (Pinus sylvestris) has been used to stabilize sand dunes, improve soil composition and create shadier environments. This has led to the degradation of psammophilous communities and a decline in biodiversity. Our study examines whether fire can help restore and maintain psammophilous beetle populations. Our research focused on two aspects: (i) the long-term effects of wildfire in 2012 on beetles (Coleoptera: Carabidae) in the "Moravská Sahara–Bzenec district" of South Moravia (period 2013–2021), and (ii) the effects of environmental factors, influenced by the aforementioned wildfire on the distribution of these beetles in the period 2016 to 2021.

Interestingly, post-fire changes in food availability emerged as the second important factor, leading to the formation of two distinct species clusters: granivorous species thrived on site dominated by graminoids, and site with accumulated CWD was attracted predominantly by carnivorous species. Implications for insect conservation: We suggest that fire management is an effective strategy for conserving and enhancing the diversity of post-fire early-successional beetle assemblages in areas where these species exist. Consequently, the increase in forest canopy closure in these habitats should not be solely regarded as regeneration or a return to a natural state. Instead, it should be considered a potential threat to their richness and diversity.

“…However, individual phytosociological studies of dry grasslands have always been restricted to either Bohemia (e.g. Kolbek, 1975Kolbek, , 1978Kolbek, , 1979Studnička, 1980;Toman, 1981Toman, , 1988 or Moravia (Vicherek & Unar, 1971;Chytrý & Vicherek, 1996;Chytrý et al, 1997;Tichý et al, 1997), which resulted in different associations being described in these regions. Of the total number of 68 associations of the FestucoBrometea class listed in the national synopsis (Kolbek in Moravec et al, 1995), only two are reported to occur both in Bohemia and Moravia.…”

Local ranges of phytosociological associations: are they reflected in numerical classification?

In the tradition of European phytosociology, delimitations of vegetation units such as associations are mostly based on data from small areas where more detailed vegetation sampling has been carried out. Such locally delimited vegetation units are often accepted in large-scale synthetic classifications, e.g. national vegetation monographs, and tentatively assigned to a small geographical range, forming groups of similar (vicarious) vegetation units in different small areas. These vicarious units, however, often overlap in species composition and are difficult to recognize from each other. We demonstrate this issue using an example of the classification of dry grasslands (Festuco-Brometea) in the Czech Republic. The standard vegetation classification of the Czech Republic supposes that the majority of accepted associations (66 out of 68) have a restricted distribution in one of the two major regions, Bohemia or Moravia. We compared the classification into traditional associations with the numerical classification of 1440 phytosociological relevés from the Czech Republic, in order to test whether the traditionally recognized associations with small geographical ranges are reflected in numerical classification. In various comparisons, the groups of relevés identified by numerical analysis occupied larger areas than the traditional associations. This suggests that with consistent use of total species composition as the vegetation classification criterion, the resulting classification will usually include more vegetation units with larger geographical ranges, while many of the traditional local associations will disappear.
