Patterns in Root Phenology of Woody Plants Across Climate Regions: Drivers, Constraints, and Ecosystem Implications
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2025) Guo, Qiwen; Rewald, Boris; Sandén, Hans; Godbold, Douglas Lawrence
Root phenology significantly influences ecosystem processes yet remains poorly characterized across biomes. This study synthesized data from 59 studies spanning Arctic to tropical ecosystems to identify woody plants root phenological patterns and their environmental drivers. The analysis revealed distinct climate-specific patterns. Arctic regions had a short growing season with remarkably low temperature threshold for initiation of root growth (0.5-1 degrees C). Temperate forests displayed pronounced spring-summer growth patterns with root growth initiation occurring at 1-9 degrees C. Mediterranean ecosystems showed bimodal patterns optimized around moisture availability, and tropical regions demonstrate seasonality primarily driven by precipitation. Root-shoot coordination varies predictably across biomes, with humid continental ecosystems showing the highest synchronous above- and belowground activity (57%), temperate regions exhibiting leaf-before-root emergence (55%), and Mediterranean regions consistently showing root-before-leaf patterns (100%). Winter root growth is more widespread than previously recognized (35% of studies), primarily in tropical and Mediterranean regions. Temperature thresholds for phenological transitions vary with climate region, suggesting adaptations to environmental conditions. These findings provide a critical, region-specific framework for improving models of terrestrial ecosystem responses to climate change. While our synthesis clarifies distinct phenological strategies, its conclusions are drawn from data focused primarily on Northern Hemisphere woody plants, highlighting significant geographic gaps in our current understanding. Bridging these knowledge gaps is essential for accurately forecasting how belowground dynamics will influence global carbon sequestration, nutrient cycling, and ecosystem resilience under changing climatic regimes.
Effects of tree features on hydrophysical soil properties in European agroforestry systems: systematic review
(Springer Netherlands, 2025) Mitrová, Anna Mária; Vichta, Tomáš; Zapletal, Petr; Volánek, Jiří; Neubauer, Štěpán; Vranová, Valerie
Hydrophysical soil properties are critical determinants of agricultural sustainability and ecosystem resilience. These properties influence soil-water dynamics, nutrient cycling, and overall soil health. Although the potential of agroforestry to mitigate soil degradation is well-established, a comprehensive synthesis of its effects on hydrophysical properties in European contexts has been lacking. This review systematically analyzes 40 studies examining the effects of woody vegetation in European Agroforestry Systems (EAFS). Findings reveal that woody components generally enhance hydrophysical soil properties across diverse EAFS. A consistent decrease in bulk density and increase in porosity were reported, leading to improved water infiltration, retention, and storage capacities. Hedgerows and shelterbelts were particularly effective in increasing hydraulic conductivity and mitigating surface runoff and erosion, with positive effects localized near woody vegetation. Silvopastoral systems demonstrated significant improvements in soil water content and infiltration rates, particularly in Mediterranean regions. However, variability was evident, influenced by tree age, species composition, spatial configurations, and management practices. Critical research gaps were identified, including limited data on subsoil dynamics, geographic biases favouring Mediterranean systems, and methodological inconsistencies across studies. Addressing these gaps through standardized protocols and multidisciplinary approaches is essential to fully realise the potential of EAFS in enhancing soil functions and adapting agro-ecosystems to climate challenges. Implementing tailored management practices that consider local climatic and edaphic conditions is essential for maximizing the hydrological and ecological benefits of EAFS.
Fire Management and Preparedness in the Czech Republic
(Springer International Publishing AG, 2024) Martínez Barroso, Petra; Winkler, Jan; Vaverková, Magdalena Daria
Fire management and preparedness in the Czech Republic (CR) is evaluated based on a broad knowledge platform consisting of official documents of the Fire and Rescue Service of the Czech Republic (FRS CR), laws of the CR, as well as scientific works from Czech universities and professional publications. The composition of the forests, mostly composed of coniferous tree species, has been conditioned by historical events and closely connects to the current health state of the Czech forests, which has been seriously affected by the bark beetle calamity. The most common types of forest fires in the CR are due to its geographical location surface fires. The main cause of fire ignition is human carelessness. The number of forest fires in the Czech Republic has an increasing tendency, however, the burnt area does not grow proportionally to the number of fires thanks to the high-quality technical equipment of the Czech firefighters and their timely response. The forest fire prevention strategy belongs to the competency of the state-owned enterprise Lesy of the Czech Republic which in cooperation with scientific institutions and universities focuses on optimizing collaboration with the Fire and Rescue Service of the Czech Republic; creation of methodologies and recommendations in the field of fire prevention; enlightenment and education of the public; and recovering the landscape capacity to maintain water. Due to changing climatic conditions, the fire regime in the CR will likely change and the current approach will need to be adjusted.

Workshop věnovaný prvnímu roku řešení projektu zabývajícího se volně žijícími zvířaty na území města Brna
(2024-02-29) Drimaj, Jakub
Workshop pojednával o průběhu řešení a prvních poznatcích projektu zabývajícího se výzkumem volně žijících savců ve městě. Tým z Mendelovy univerzity prezentoval výsledky z nočních monitoringů veřejné zeleně, monitoringu krizových situací spojených s výskytem savců v Brně a informoval o zahájení monitoringu pomocí fotopastí a odchytu netopýrů. Byla také podána zpráva o vzorkování a monitorování výskytu invazních druhů (např. mývala severního, psíka mývalovitého, nutrie říční). Tým SocioFactor, s.r.o., seznámil s výsledky monitoringu médií a přístupu občanů k volně žijícím zvířatům. Tým z Masarykovy univerzity prezentoval výsledky hodnocení zdravotního stavu volně žijících savců.
