In the context of global climate change and rising anthropogenic loads, outbreaks both endemic invasive pests, pathogens, diseases pose an increasing threat to health, resilience, productivity natural forests forest plantations worldwide. The effective management such threats depends on opportunity for early-stage action helping limit damage expand, which is difficult implement large territories. Recognition technologies based analysis Earth observation data are basis tools monitoring spread degradation processes, supporting pest population control, management, conservation strategies in general. this study, we present a machine learning-based approach recognizing damaged using open source remote sensing images Sentinel-2 supported with Google example bark beetle, Polygraphus proximus Blandford, polygraph. For algorithm development, first investigated annotated channels corresponding color perception—red, green, blue—available at Earth. Deep neural networks were applied two problem formulations: semantic segmentation detection. As result conducted experiments, developed model that quantitative assessment changes target objects high accuracy, achieving 84.56% F1-score, determining number trees estimating areas occupied by withered stands. obtained masks further integrated medium-resolution achieved 81.26% opened operational systems recognize region, making solution rapid cost-effective. Additionally, unique dataset has been collected polygraph region study.

Disturbances, both natural and anthropogenic, affect the configuration, composition, function of forested ecosystems. Complex system behaviors emerge from interactions between disturbance regimes, vegetation response to those disturbances, their interplay with multiple drivers (climate, topography, land use, etc.) across spatial temporal scales. Here, we summarize conceptual advances empirical approaches interaction investigation, used insights evaluate categorize 146 landscape modeling studies emerging a systematic review literature published since 2010. Recent include formal disaggregation disturbances into constituent components, embedding processes dynamics, clarifying terminology for factors, types, ecosystem responses. Empirical investigating now span wide range approaches, including (most recently) advanced statistical methods applied an expanding set datasets. Concurrent development in spatially-explicit models, informed by these insights, integrate among anthropogenic coupling account stochasticity, within scales, non-linear responses climate change. Still, trade-offs model elegance complexity remain. We developed index degree process integration (i.e., balance static vs. dynamic components) given agent it our review. Contemporary applications this line research have integration, depending on specific question, but also limited part data knowledge.

Understanding planning uncertainty behavior—including interactions—is paramount at time accelerated While progress area is evident, work remains increase transparency confidence, especially understudied processes.

Insect pollination establishes an ecosystem service around the globe, providing compelling budgetary and creative profits along with developmental values to humans vital eco-friendly measures for environment. It is, therefore, essential understand how insect pollinator populations communities respond rapidly changing environments if we are maintain healthy effective services. Although pollinators known provide services more than 80% of world's flowering plants (including cultivated crops), a steep decline (∼20–40%) in their population has created alarming situation global biodiversity. Threats bee recent years have increased awareness about critical role life on earth, as predicted persist only when all animal-pollinated plant species persist. Additionally, usage chemical pesticides may result collapse which leads decrease food resource density also facilitates increasing isolation natural habitats. So, overcome pollinators' decline, joint efforts stakeholders needed increase numbers planet. We cut down use synthetic pesticides, ban highly toxic tackle problems related colony disorder (CCD), climate change, habitat loss much-needed help native revive this paper aims focus appreciating rescuing them from threats leading extinctions turn will enhancing production.

Abstract Trees contribute greatly to urban environments and human well-being, yet relatively little is known about the extent which a rising incidence of tree insect pests pathogens may be affecting these contributions. To address this issue, we undertook systematic review synthesis diverse global empirical evidence on impacts pathogens, using bibliographic databases. Following screening appraisal over 3000 articles from wide range fields, 100 studies 28 countries, spanning 1979–2021, were conceptually sorted into three-part framework: (1) environmental impacts, representing 95 studies, including those reporting damage, mortality, reduced growth, changes in function; (2) social reported by 35 aesthetics, health, safety hazards; (3) economic 24 costs pest management, losses. There has been considerable increase impact since 2011. Evidence gaps exist climate-regulating capacity, temperature regulation, water retention, soil erosion, wind protection, but also specific hazards, nuisances, property damages, hazard liabilities. As knowledge synthesis, article presents best available / pathogen guide policy, management further research. It will enable us better forecast how growing threats affect forest plan for eventualities.

Forest canopies host an abundant but often neglected diversity of arthropods, which requires careful attention in times ongoing biodiversity loss. Yet, how tree species composition interacts with canopy structure shaping arthropod communities remains largely unknown. Here, by combining mobile laser scanning and insecticidal fogging a machine learning algorithm, we studied architectural properties affect monospecific mixed stands broadleaved European beech the coniferous Norway spruce non-native Douglas fir Germany. Evaluating abundances ecological guild ∼ 90,000 arthropods 27 partly novel high-resolution structural variables, identified vegetation volume identity as weak predictors abundance diversity. In contrast, heterogeneity, i.e. complexity, vertical layering variability gaps—which were highest stands—were strong positive drivers. Despite this, was lower fir. Mixed had intermediate Our study shows that habitat heterogeneity species-identity are closely interlinked associated communities. Positive effects on uncoupled from resource availability, key role our intra-canopy gap indices suggests they should be considered indicators future research forest heterogeneity-diversity relationships. Broadleaf-conifer mixtures may suitable to mediate negative tree-species when adapting forests global change.

Abstract Natural disturbances are important drivers of forest dynamics, and canopy gaps their fingerprints in ecosystems. Gaps form persist because the interplay tree mortality regeneration. They can have long‐lasting impacts on ecosystems, yet temporal dynamics gap formation closure remains poorly quantified. We analysed 11,331 changes through time across 3999 ha unmanaged temperate mountain forests at Berchtesgaden National Park (Germany). assessed using three repeat lidar acquisitions between 2009 2021, analysing height 1 m horizontal resolution. Our objective was to determine dominant mode formation, distinguishing creation new from expansion existing ones. Additionally, we studied rate closure, considering regeneration lateral crown expansion. Gap primarily driven by rather than initiation gaps. accounted for 81.3% although were average twice as large expansions. Only 1.4% did not expand over 12‐year study period, Norway spruce had highest Overall, (0.74 100 −1 year ) higher (0.58 our system. Ingrowth regenerating cohort primary with accounting 20% all area closed. Mixed‐species stands <0.1 closed faster larger Synthesis . While openings generally small European Alps, show that they keep growing multiple years, underlining is an driver dynamics. Canopy created, highlighting resilience natural disturbances. However, projected increase under climate change, this might be challenged future, requiring a continuous monitoring early warning indicator change.
