In this study, Sentinel-2 and Sentinel-3 Copernicus satellite data resampled to 20 m<sup>2</sup> spatial resolution was used to characterize the annual cycle of spectral eco-physiological traits in 176 patches invaded by <em>Ailanthus altissima</em> (Mill.)

Moreover, in the competition term we take into account the fact that the two populations of plant interact in a 3D space and the interaction occurs on the borders of the vegetation patch and/or volume, meaning that both densities will be characterized also by two exponents. A complete mathematical analysis of the proposed model was done by studying also some particular cases of it.

This study assessed the beekeeping suitability of the Amazonas region and its variation under climate change scenarios in two projected periods (2041–2060 and 2081–2100), according to Shared Socioeconomic Pathways (SSP). The methodological framework integrated the Analytical Hierarchy Process (AHP) with Geographic Information Systems (GIS), and the Hadley Centre Global Earth Model - Global Coupled configuration 3.1 (HadGEM3-GC31-LL) was used for future climate analysis. The beekeeping suitability of the region was determined based on eleven criteria: four climatic, three topographic, and four environmental. The results indicate that beekeeping suitability is distributed as follows: 3.4 % (1417.90 km<sup>2</sup>) with ‘High’ suitability, 79.2 % (33,318.61 km<sup>2</sup>) with ‘Moderate’ suitability, 17.2 % (7230.26 km<sup>2</sup>) with ‘Marginal’ suitability, and 0.2 % (83.64 km<sup>2</sup>) as ‘Not suitable’. Moreover, the average temperature across the region is projected to increase by approximately 3 °C under the SSP2–4.5 scenario and between 6 °C and 8 °C under the SSP5–8.5 scenario during the projected periods. Precipitation will decrease in the northern part of the region, while the southwestern part will experience an increase.

Additionally, a reduction in precipitation up to 311 mm/year is projected, with predominant variations ranging from −49.5 to −32.8 mm/year over approximately 600 km<sup>2</sup>.Therefore, it is suggested to implement strategies to mitigate these upcoming challenges, particularly if the modeled economic development under the SSPs continues.

Remote sensing offers a promising tool for monitoring these impacts, but challenges persist in heterogeneous grassland systems. This study combines radiative transfer model (RTM) and machine learning algorithms to assess the efficacy of the model inversion in predicting plant functional traits under different grassland management regimes. The model was applied to intensively and extensively managed grasslands using field-collected hyperspectral data. Results show that while RTM inversion effectively predicts traits such as leaf area index (LAI) and pigment concentrations in homogeneous, intensively managed systems, its accuracy diminishes in diverse, extensively managed grasslands, particularly for traits like leaf mass per area (LMA) and pigment content. These limitations stem from the model’s assumption of homogeneous canopy scattering, which fails to account for the heterogeneity in mixed green and brown vegetation, especially at senescence. Despite these challenges, the study highlights the potential of hyperspectral remote sensing to capture grassland management based on a solely empirical approach. Future research should focus on refining models to better account for canopy heterogeneity and integrating in-situ data to improve trait prediction in complex ecosystems.</div></div>","PeriodicalId":51024,"journal":{"name":"Ecological Informatics","volume":"87 ","pages":"Article 103068"},"PeriodicalIF":5.8,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
