The Trans-Mexican Volcanic Belt (TMVB) supports high reptile endemism, yet the degree to which species’ potential habitats intersect fire-prone environments remains poorly quantified. In this study, we analyzed the spatial and temporal relationships between fire occurrence and reptile habitat by integrating species distribution models, fire risk layers, land cover loss, and landscape metrics across 38 endemic reptile species. From 2001 to 2023, fire-related tree cover loss increased across the region. Associations between annual fire loss and broad-scale climatic indices (Oceanic Niño Index and SPEI) were weak, indicating that climate alone may be insufficient for explaining observed dynamics. These patterns are consistent with an important contribution of human land use, although causation cannot be directly inferred. Spatial overlays showed that notable fractions of the predicted distributions occurred in areas with elevated fire probabilities: ∼12% in the medium category and ∼6% in the high category. Some taxa exhibited particularly large exposures. In environmental space, principal component analyses revealed visible coincidence between reptile habitats and conditions associated with fire; however, the quantitative overlap metrics were generally low, and equivalency tests were nonsignificant. This suggests limited environmental similarity and indicates that fires tend to occur within broader tolerances rather than near predicted suitability optima. After the fire probability was incorporated, many species exhibited a reduction in the number of habitat patches. Taken together, these results highlight the widespread exposure of endemic reptiles to contemporary fire regimes. Integrating disturbance probability with climatic suitability may strengthen conservation planning in rapidly changing montane landscapes.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"130 ","pages":"Article 104157"},"PeriodicalIF":1.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147396699","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}

Wisents upon having been reintroduced to the Bieszczady Mountains, have remained in two separate subpopulations of slightly different habitats. In this study, we compared the affiliation to their home ranges. Using movement data obtained through radio-tracking and employing machine learning techniques (notably, eXtreme Gradient Boosting) for classification purposes, we were able to obtain a precise determination of the most intensively used habitats within their home ranges. We analysed 31,480 location records of wisent presence in the Bieszczady Mountains during the years 2002–2021, and correlated this with data on land use and land cover obtained from the Corine Land Cover inventory. The machine-learning algorithm XGBoost was then applied to identify the affiliation of individual wisents to habitats within the home range of the given subpopulation. The results showed very high classification performance, with a recognition accuracy of 92 % in the vegetative and 96 % in the winter seasons. We thus propose a new approach to recognizing the affiliation of particular individuals to their home ranges.

We conducted field and laboratory experiments to evaluate the seed-burial ability of dung beetles in parallel with investigations into the composition of seeds in dung and the capture of dung beetles. The experiments demonstrated that large tunnellers, mainly <em>Phelotrupes</em> spp. in summer and <em>Copris</em> spp. in fall, buried experimental seeds (plastic beads) at a depth of 0.5–5 cm regardless of size, implying that the buried seeds had a high probability of escaping predation and desiccation. Therefore, the large dung beetles at our study site seem to contribute more to secondary seed dispersal. We found that the percentage of seed-burying was greatest in summer when the abundance of <em>Phelotrupes</em> spp. was higher.

Numerous studies on food selection have identified the palatable plant species preferred by large herbivores. However, intra-specific food selection and the question why particular plants of a given species are ignored during foraging have been neglected. Blackthorns growing in abandoned pastures are an important component of the deer's diet. In areas densely populated by deer, annual shoot browsing produces dwarf shrubby forms of blackthorns. However, some blackthorns are not browsed by ungulates (resist or escape herbivore control) and adopt a tree-like form. The existence of distinct, browsing-dependent growth forms of blackthorns raises the question of inter-individual differences in the nutritional composition of plants. We discovered differences in nutritional composition between browsed (dwarf) and unbrowsed (tree-like) blackthorns that might explain the individual plant-related drivers of deer food preferences. The leaves of browsed blackthorns contained higher concentrations of C, N, P and Cu but lower levels of Ca and Mg than unbrowsed ones. Moreover, browsed blackthorns had a higher water content and higher concentrations of insoluble proteins, chlorophylls and carotenoids. The nutritional characteristics of an individual plant may explain the observed food selection pattern, leading to the unhindered growth of a fraction of the blackthorn population, in spite of severe pressure on the part of ungulate herbivores. The results underline the important role of herbivores in the dynamics of plant communities, in which ungulates may mediate the persistence of certain individuals of a given species.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"129 ","pages":"Article 104130"},"PeriodicalIF":1.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416963","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}

We used two MODIS products which provides GPP and net primary production (NPP) to quantify the photosynthetic activity and biomass of an urban forest in Tijuca National Park (Rio de Janeiro, Brazil) and a non-urban forest of comparable size and climate region between the years 2004 and 2024.

Urbanization and rainy seasons together positively influenced GPP and biomass increase, indicating a synergistic effect of urbanization and rainfall on the production dynamics.
