This study analyses the bark beetle species spectrum (Scolytinae) in supranational migration across the Czech Republic (2020–2025) using a Johnson-Taylor suction trap network. Out of 2 129 identified individuals (45 species), Pityogenes chalcographus (Linnaeus, 1761) and Crypturgus cinereus (Herbst, 1793) were dominant, with their 2021 outbreak temporarily altering the community's proportional abundance. Ecological indices (H', J') confirmed an acute internal asymmetry caused by massive pest flights. The findings support the dispersal flight phenomenon, where individual scattering into vast air volumes explains the...

Uneven-aged forest management and Continuous Cover Forestry (CCF) are increasingly discussed as adaptive silvicultural approaches capable of improving forest resilience under climate change, increasing disturbance frequency, and growing uncertainty in forest ecosystems. However, the conversion of structurally homogeneous stands into uneven-aged structures represents a complex optimisation problem involving economic performance, structural stability, regeneration continuity, and long-term sustainability. This study presents a multi-period optimisation framework based on size-class dynamics, transition matrices, and Liocourt-based structural regulation....

Forest fires are becoming an increasingly serious environmental and social problem, driven by climate change and growing anthropogenic pressure. While their ecological aspects have been widely studied, less attention has been paid to social perception and its impact on fire management. The aim of this study is to analyse the social perception of forest fires among respondents residing in Poland, with particular emphasis on levels of knowledge, attitudes, and perceived risk. A quantitative (Computer-Assisted Web Interview, CAWI) survey was conducted between November 2025 and February 2026, involving 246 participants. Statistical analyses included non-parametric...
Differential responses of BVOC emissions in Pinus massoniana to drought stress and rehydration: Implications for climate change and air qualityOriginal Paper

Drought has been demonstrated to exert a substantial influence on the growth of plants and the chemical emissions thereof. The present study aims to examine the alterations in biogenic volatile organic compound (BVOC) emissions and chemical compounds in Pinus massoniana seedlings under the conditions of drought stress and subsequent rehydration. The findings revealed that drought stress and rehydration significantly altered the emission of total BVOCs, monoterpenes, and sesquiterpenes, with isoprene emission showing only a marginal decrease. Under conditions of drought stress, the emission of total BVOCs, monoterpenes and sesquiterpenes increased...
