This study assessed patterns of species abundance and diversity of street trees based on origin, fruit-bearing status, and tree size classes in Macapá, Northeastern Brazilian Amazon. Street trees were systematically inventoried along urban blocks across all administrative zones of the city. We recorded 52 species, most of them exotic (75%) and fruit-bearing (52%), reflecting colonial legacies and local preferences for utilitarian species, especially those used for food production. Notably, none of the native species identified were endemic to the Amazon biome, indicating predominance of widely distributed taxa even among natives used in urban landscaping. Species richness was similar between small (41 species) and medium-sized trees (41), but declined markedly among large trees (24). This is the first study in the region to apply a systematic field inventory of street trees, revealing a concerning trend: mature, tall species are being replaced by smaller, fast-growing ones. This shift suggests a reduction or potential loss of important ecosystem services typically associated with large-canopy trees, such as shade provision, carbon storage, and habitat availability for urban fauna. We also found low average tree density (9.78 ± 2.16 individuals km⁻¹; mean ± standard deviation), emphasizing the need for afforestation planning that prioritizes biodiversity, ecological functionality, and climate resilience. Our findings underscore the importance of management strategies that consider species composition, functional traits, and spatial distribution to effectively meet socioenvironmental demands in tropical urban settings.</p>","PeriodicalId":11434,"journal":{"name":"Ecological Research","volume":"41 2","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esj-journals.onlinelibrary.wiley.com/doi/epdf/10.1111/1440-1703.70059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147584997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Testate amoebae, a diverse group of microbial eukaryotes driving important ecological functions, are particularly suited for trait-based analysis due to their considerable morphological variability. However, traditional classifications of testate amoebae rely primarily on morphology, potentially overlooking ecologically relevant information. This study developed a novel system of functional groups for testate amoebae based on 18 functional traits and assessed its ecological significance. We used hierarchical clustering on a trait database encompassing 372 species from the Northern Holarctic realm. Our analysis identified seven distinct functional groups, which reflect adaptive strategies linked to shell size, aperture traits, and feeding modes: large-bodied predators (Groups 1 and 2), medium-sized bacterivores (Groups 3–5), patelliform generalists (Group 6), and small, highly adaptable taxa (Group 7). A case study in the Eastern European Plain revealed that organic soils harbored greater functional diversity, with species spanning all groups, while mineral soils were dominated by Group 5 (hemispheric, drought-tolerant bacterivores). Functional space ordination highlighted habitat-driven divergence, with organic soil communities characterized by traits optimizing resource exploitation (e.g., straight terminal apertures, idiosome shells) and mineral soils favoring desiccation-resistant morphologies (central ventral apertures, compact shells). The new functional classification provides a more comprehensive understanding of the testate amoebae's ecological functions and improves our ability to predict their responses to environmental change.</p>\u0000 </div>","PeriodicalId":11434,"journal":{"name":"Ecological Research","volume":"41 2","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
