The latitudinal diversity gradient (LDG) represents one of the most widespread patterns in nature, although some groups, such as mites, have shown inconsistent responses to its underlying predictions. Based on data on mites associated with rubber trees <em>Hevea brasiliensis</em> Muell. Arg. (Euphorbiaceae) in Brazil, our objective was to assess the impact of environmental and spatial factors on species diversity, specifically focusing on predators and phytophagous mite functional groups across a latitudinal gradient. Mite communities were sampled at 55 locations across four phytoecological regions. Species richness was analyzed according to environmental characteristics and spatial coordinates as explanatory variables. The LDG demonstrated a significant positive correlation for predatory mites, however, this pattern was not observed for phytophagous mites, likely due to their inherent association with the host plant, surpassing the influence of other processes. Spatial scale played a crucial role in shaping the composition of both groups, with a particularly strong influence on predators. Environmental factors, such as precipitation and forest formation, exhibited a more pronounced relationship with predators. Richness and composition of both groups varied across phytoecological regions. The functional approach further revealed variations in the relative influence of spatial and environmental processes, with predators responding mainly to abiotic drivers, including climatic and landscape factors, and exhibiting a latitudinal distribution pattern, while phytophagous mites appeared more influenced by biotic interactions with the host plant.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"129 ","pages":"Article 104133"},"PeriodicalIF":1.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145363186","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}

There are few studies that explicitly link plant biological traits and seasonal edaphic variability to colonization dynamics. The objective of this research was to evaluate the existence of patterns in the arbuscular mycorrhizal association of three Asteraceae family species of secondary vegetation, <em>Ageratina glabrata</em>, <em>Roldana angulifolia</em> and <em>Roldana barba-johannis</em>, explained by some biological traits of the plant species and some edaphic factors of the site. Significant differences in AMF colonization were detected. Hyphae and spore colonization increased during the rainy season, while arbuscule frequency increased during the dry season. Generalized linear model results showed that species identity and its interaction with the site significantly affected plant height and coverage. <em>R. barba-johannis</em> exhibited a significant and positive correlation between coverage and arbuscule colonization. Canonical correspondence analysis revealed that fungal colonization was primarily associated with higher soil moisture, organic matter, and nutrient availability during the rainy season. Conversely, arbuscule colonization and plant growth during the dry season were related to light availability and ammonium levels. It was shown that AMF colonization of Asteraceae shrubs is strongly influenced by a combination of biological, edaphic and seasonal factors.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"129 ","pages":"Article 104128"},"PeriodicalIF":1.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159434","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}

To address this knowledge gap, we selected a 420000-ha landscape consisting of MWs and TBSC to investigate the impact of anthropogenic disturbances on BPRs and the underlying mechanisms, while accounting for abiotic and biotic factors. MWs conversion to TBSC altered the diversity-biomass relationship from positive to neutral. Both MWs and TBSC showed a positive net biodiversity effect, which was mostly due to niche complementarity. In MWs, both stem density and basal area mediated the effect of diversity on tree C storage; however, in TBSC, stem density had a neutral mediation effect, resulting in a neutral BPR. Climatic water availability and fire frequency showed a positive and negative total effect on tree C storage in MWs, respectively, but had no effect in TBSC.

Movement is closely associated with the response of species to landscape changes, with more vagile species typically being less affected. In Odonata, movement capacity is strongly related to body morphology, such as wing and body size. In general, species in the suborder Anisoptera have larger wings and bodies than species in the suborder Zygoptera and are likely to move over greater distances. In this paper, we synthesize knowledge about the movement capacity of adult Odonata based on a literature review. We also assess whether travel distances differ between the suborders (Anisoptera and Zygoptera), and whether these movements are consistent with the spatial scales used in landscape studies (i.e., the spatial extent at which landscape metrics are measured). We found 34 articles published between 1978 and 2025, from which we obtained movement data for 32 species (17 Anisoptera and 15 Zygoptera). Most studies were developed in the northern hemisphere, with an increase since the early 2000s. Individual movement is usually assessed by mark-recapture, but telemetry has been applied for large-bodied species. Despite the literature suggesting a higher movement capacity in Anisoptera than in Zygoptera, we observed no significant difference between the two suborders. Our results showed a median distance of 731.5 m (range: 16 to 1790 m) for Zygoptera and 224 m (range: 89 to 1910 m) for Anisoptera. Landscape studies were rare, and some spatial scales used were small compared to the maximum travel capacity of Odonata. Based on these results, we emphasize the scarcity of data on dragonfly movements, especially in tropical regions. Understanding these factors is essential to identify needs and define conservation strategies, especially for species most sensitive to anthropogenic changes, threatened and low movement capacity.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"129 ","pages":"Article 104125"},"PeriodicalIF":1.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221673","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}
