The aim of this study was to evaluate the chemical control of this invasive species within a Private Natural Reserve located in the Tandilia Hill System and to assess the natural succession of vegetation after tree removal. To achieve this, an experiment was conducted using a Randomized Complete Block Design with four replications and four treatments. In three treatments, different herbicides were applied, while one treatment served as a control. From November 2016 to October 2018, vegetation species were recorded. The variables analyzed included green foliar coverage of the acacias, green foliar coverage of the Poaceae assemblage, and vascular species richness. Significant differences in green foliar coverage of acacias were detected between treatments on all sampling dates. An increase in the average green foliar coverage of the Poaceae assemblage was observed in the Picloram + Triclopyr treatment. No significant differences in species richness were detected between treatments at the final sampling date. This study demonstrated the effectiveness of the chemical treatments in controlling young <em>A. melanoxylon</em> trees. Furthermore, after a considerable time had passed since the application of the treatments, the Poaceae group and the percentage of native species were not negatively affected. This suggests that chemical control can not only be useful for managing this invasive tree species but can also contribute to the recovery of native ecosystems in the Tandilia Hill System.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"86 ","pages":"Article 126931"},"PeriodicalIF":2.2,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 distribution data for 1,123 plant species and 18 environmental predictors (climate, soil and altitude) to project species response to two radiative forcing scenarios: SSP2-4.5 and SSP5-8.5 using MaxEnt. The species responses were analysed by the species range and richness in climate change scenarios compared to the current climate. In both forcing scenarios, the number of species expected to decrease their geographic ranges was twice the number expected to increase. The species range decrease varied by growth form, with averages from 4.19 % to 10.31 % in SSP2-4.5 and 11.9 % to 21.79 % in SSP5-8.5. We observed an 8 % and 41 % decrease in species richness under the SSP2-4.5 and SSP5-8.5 scenarios, respectively. Trees and herbs had the highest average species loss per area in both scenarios. The species loss was primarily observed in the southern and southeastern regions, where an increase in average annual temperature and the greatest decrease in average annual precipitation is expected.

Our findings reveal that pumas in this landscape did not consume prey in proportion to their abundance. Wild species, particularly capybaras (<em>Hydrochoerus hydrochaeris</em>) and giant anteaters (<em>Myrmecophaga tridactyla</em>), were the primary prey items. This suggests a specialized diet, potentially influenced by prey availability and accessibility. The estimated mean kill rate was 0.94 ± 0.5 prey/week, and pumas hunted every 2.8 ± 1.15 day. The mean weight of prey was 2.3 kg (range: 1–100 kg), which is lower than reported in temperate regions. Our models suggest that total time spent at a kill site was the primary predictor of predation events.
