Forest fires represent a natural element in the dynamics of forest ecosystems. This study investigated impact large-scale fire 2022 (ca. 1300 ha) on epigeic ground beetles (Coleoptera: Carabidae). The research was conducted coniferous forests at six pairwise sites: burnt and unburnt dead spruce from bark beetles, clear cut, healthy sites. Each site replicated four plots, with two pitfall traps deployed within each plot. In total, 48 (6 × 4 2) were installed April 2023. It tested how individual sites affected similarity beetle communities, whether they contained similar life guilds, significantly affects abundance pyrophilous beetles. A total 5952 individuals 63 species recorded. We observed significant decline clear-cut (73% 77.5%, respectively) compared to Conversely, increased by 88% site. Additionally, differences number per trap richness diversity (q = 0, q 1, found only between general, highest comparison all Communities responded considerably fire, differing sites, demonstrating high degree similarity. original stands had highly homogeneous communities.

Understanding post-fire processes can provide important guidance for management areas designated biodiversity enhancement.

Deadwood plays a key role for biodiversity in forests. A significant number of beetles from this group are currently listed as endangered the Red List. In addition to other management recommendations, there have been recent efforts enrich stands with dead wood promote biodiversity. An important parameter forestry enterprises is optimization these interventions. The study investigated abundance, species richness, gamma diversity, conservation value and biomass saproxylic natural forests using window traps. total 89 traps were used beetle monitoring, which 29 placed on lying logs, 30 snags controls forest stand space. 35,011 recorded 564 (61 families). Notably, 20,515 belong (59%) 311 (55%), 62 classified Red-List (20%). 'all beetles', results indicate that α diversity γ (q = 0) remain consistent across various deadwood types, while β showed differences. Significant differences found group, where differed, higher values observed snags. Rarefaction based richness site was estimated 391 species, including 74 Red-Listed species. Comparing sample coverage studied categories all exhibit pronounced preference inhabiting areas featuring logs. Conversely, mainly inhabit snags, being more similar both (weighted average by status) significantly highest whereas space show lowest measured indices. Furthermore, use set poles resulted an underestimation actual 20%–25%. Our support conclusion indispensable feature beech forests, playing promoting high especially among supporting beetles. Consequently, it becomes crucial incorporate percentage standing managed or actively create equivalent environments introducing stumps.

Snags are an important component of beech forests that promote biodiversity. However, their occurrence is completely marginal in managed stands. Creating snags these stands would greatly enhance We investigated whether snag dimensions were for saproxylic beetle richness since they easily transferable parameters to forest management and assessed the presence other microhabitats affecting communities. Data collection was performed using passive flight traps placed on thirty a recent reserve. A total 6706 adults belonging 231 species (53 Red List species, 23%) captured. The results showed most diameter (thickness) canopy openness surrounding Fomes fomentarius, volume decay class 3 marginally significant terms preference all species. Alpha diversity reduced by advanced degree surprisingly deep stem cavity. After dividing thickness into categories (<35; 35–70; >70 cm DBH), we found with greater than 35 little differences indices exhibited highest similarity Regarding recommendations managers optimization simplification practical procedures, suggest actively creating high stumps act as DBH biodiversity

The saproxylic beetles (deadwood-dependent) belong to frequently studied groups of forest insects. Eucnemidae is a rare and poorly family with hidden life strictly related deadwood. We the in beech reserve, using 59 window traps placed on standing deadwood (snags) lying logs. A total 348 specimens eight species were recorded two seasons. identified included one critically endangered (CR): Hylis cariniceps; five (EN): H. olexai, foveicollis, Isorhipis melasoides, Eucnemis capucina, Microrhagus lepidus; new found Bohemia (a region Czech Republic): Clypeorhagus clypeatus; common species: Melasis buprestoides. Most preferred logs, but E. capucina M. buprestoides snags. Species richness (q = 0) was higher logs than snags, similarly, Shannon diversity 1) significantly compared C. clypeorghagus, cariniceps, lepides moist while drier snags cavities. results suggest that forests, serve as fundamental habitat for existence Eucnemids. This could be due more stable microclimatic conditions inside From this perspective, our study may help better understand biology understudied
