This, however, remains elusive due to the sheer complexity of ecological processes. The maximum entropy-based Community Assembly via Trait Selection (CATS) model was designed to quantify the relative contributions of trait-based filtering, dispersal mass effects, and stochastic processes on community assembly. As a maximum entropy model, it does so without introducing additional bias or assumptions. Despite its increasing use, questions regarding its robustness and potential limitations remain. Here, we compared model predictions using either local or database-derived trait values, across different levels of species richness and between different taxonomic levels. A total of 19 datasets and 790 plots were analysed, spanning multiple habitat types (n = 18) and biomes (n = 7). Results indicate trait value origin does indeed influence model outcomes, warranting caution in selecting the method for obtaining trait data. We hypothesise that, for example, intraspecific trait variation combined with trait-based filtering or stochastic processes causes local and database trait values to deviate, potentially even further exacerbated by imputing missing trait data. Furthermore, trait-related information obtained from the model decreased with increasing species richness. We further hypothesise this could signal that stochastic processes are more dominant within species-rich systems, for example, due to functional redundancy or the existence of multiple fitness strategies. This general pattern was conserved across biomes, although with varying strength, showing CATS’ robustness despite these challenges.</div></div>","PeriodicalId":51024,"journal":{"name":"Ecological Informatics","volume":"86 ","pages":"Article 103031"},"PeriodicalIF":5.8,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143227477","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}

Typically, it is based on multispectral satellite images with low (∼250 m) to moderate ground pixel resolution (∼20 m). However, in small, fine-scale ecosystems such as peatlands, the representation of CO₂ fluxes heterogeneity across microhabitats is very limited by the ground pixel resolution of satellites. In this context, high ground pixel resolution of drone imagery might prove useful, alone or in synergy with large-scale satellite data, to better support field investigations and carry out rapid carbon assessment at a relatively low cost. Here, we carried out a survey of CO₂ exchanges over 4 ha of peatland during the growing season using chamber measurements, as well as simultaneous aerial multispectral orthophotographs acquired by drone. To assess the ability of drone multispectral images at providing relevant information for the prediction of CO₂ fluxes, we developed robust linear regression models and used drone imagery to map net ecosystem exchange, ecosystem respiration and gross ecosystem productivity at a very fine scale (∼5 cm). Our predictions were in the range of those found in the satellite remote sensing literature with errors lesser than 0.5 gCO₂.m⁻².h⁻¹. Our study offers new opportunities to refine large scale satellite assessment of CO₂ fluxes on small, valuable peatland areas that can be easily flown over by drone.

The aim of this study was to define reef benthic habitat states and explore their spatial and temporal variability on a global scale using an innovative clustering pipeline. For this purpose, we used substrate cover data collected along 6554 transects worldwide by citizen scientists contributing to the <em>Reef Life Survey</em> program. We applied an innovative clustering pipeline that combines three algorithms — <em>Uniform Manifold Approximation and Projection</em> (<em>UMAP</em>) for dimension reduction; <em>Hierarchical Density-Based Spatial Clustering of Applications with Noise</em> (<em>HDBSCAN</em>) — to identify benthic habitat states and Shapley values to interpret the clusters identified. This unsupervised pipeline identified 17 distinct clusters worldwide, representing typical temperate and tropical benthic habitats such as large canopy forming algae and branching corals, respectively, as well as transitional states between different habitat states. Temporal site-specific analyses further demonstrated the pipeline's effectiveness in capturing fine-scale habitat dynamics. By providing a standardised, scalable approach, this work enables consistent tracking of benthic habitat changes across spatial and temporal scales worldwide.

Accurate prediction of pasture availability is critical for effective farm management, livestock growth, and maintaining the supply chain.

However, different pasture species respond to climate attributes with varying time lags; for example, one species might be more influenced by last week’s weather while another by the previous month’s highlighting the nuanced temporal dependencies. This time-lagging effect complicates the development of machine-learning models that can learn the temporal dependencies to predict pasture yield.
