This study assessed these services in the São Francisco Xavier Environmental Protection Area in Brazil. The objective was the economic value of aspects of biodiversity, considering the conservation of ecosystems. The method involved identifying relevant ecosystem services associated with local biodiversity and the corresponding economic indicators, then assessing the biodiversity status of the area and integrating this as a weight in the valuation equation. The total economic value of ecosystem services in EPA-SFX was US$4,684.81 per hectare. The study concluded that current financial incentives for biodiversity conservation, such as the Payment for Environmental Services programs, were insufficient compared to the intrinsic value of ecosystem services. The findings emphasize the need to reform valuation models and establish effective financial mechanisms for biodiversity conservation. They also demonstrated that incorporating habitat quality into the valuation equation enhanced the accuracy of the results, bringing them closer to the local context, representing an innovative contribution to this study.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 3","pages":"e20240775"},"PeriodicalIF":1.2,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148723153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated phenological patterns in naturally regenerating areas following bauxite mining, compared with altered primary forests in a degraded landscape of the eastern Amazon. From August 2022 to July 2023, we monitored flowering (flower buds and flowers at anthesis) and fruiting (immature and mature fruits) phenophases, calculated activity and intensity indices, applied circular statistics, and categorized species by trophic resource type (nectar, pollen, fleshy fruits). Phenophases occurred year-round, with more species and individuals active in regenerating areas than in primary forests. Similar flowering and fruiting periods across habitats suggest climatic control, while higher phenophase intensity in regenerating areas likely reflects reproductive strategies and environmental conditions. These findings underscore the complementary role of regenerating and primary forests in sustaining resource supply, which is critical for maintaining fauna and trophic interaction networks during habitat recovery.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20250907"},"PeriodicalIF":1.2,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148719453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data on the number and total area of farms with AGF from the 2006 and 2017 Agricultural Censuses, data on the values and number of contracts allocated to the ABC Program, and those specific to the integrated systems credit line from the Rural Credit Data Matrix of the Central Bank of Brazil were analyzed. The findings revealed an expansion of AGF areas, particularly in Northeast Brazil, and dispersion to other regions, notably Mato Grosso and Mato Grosso do Sul states. Econometric estimates confirmed that this expansion was heterogeneous across regions but not significantly associated with ABC Program credit. Most microregions did not access these resources, with those that did primarily in the Midwest and South. Consequently, the AGF expansion in Northeast Brazil was not driven by the ABC Program's rural credit.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20251287"},"PeriodicalIF":1.2,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148722412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method was secondary data analyses using national datasets in the public domain. Only records of disasters recognised by the Federal Government were selected. In total, 19,026 records of disasters and their impacts were analysed, including 949 Brazilian municipalities. The results showed that as the number of dead, injured, and ill people grows, the number of damaged health facilities also tends to increase for all years. However, the correlation coefficient was weak, except for the years 2013, 2014 and 2015, which was moderate. The spatial distribution of municipalities with the highest disaster-related expenditures is concentrated in the states of Amazonas, Pará, Acre, Mato Grosso do Sul, and in some states in the Northeast. Hydrological (flooding and flash floods) have caused the most damage and destruction of health services. The indicators of disaster risk management do not explain the variation in the occurrence of damaged or destroyed facilities, because the coefficient values indicated a very weak correlation.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 suppl 1","pages":"e20250681"},"PeriodicalIF":1.2,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148720302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the therapeutic effects of a hyaluronic acid (HA) hydrogel associated with silver (HA+Ag) on partial-thickness burn wounds in mice, through macroscopic, morphometric, microscopic, and molecular analyses. Seventy-two BALB/c mice were divided into four groups: Control (saline), SSD (1.0% silver sulfadiazine cream), HA (1.0% hyaluronic acid hydrogel), and HA+Ag (1.0% hyaluronic acid hydrogel + 0.5% silver). At 7 days after injury (DAI), the HA+Ag group showed significantly greater wound contraction compared to the Control. Microscopic analysis revealed increased angiogenesis and fibroblast presence in the HA and HA+Ag groups, suggesting enhanced granulation tissue formation. No significant differences were observed in collagen fiber deposition. Gene expression analysis at 7 DAI showed higher levels of IL-1β, TNF-α, and IL-10 in the Control group, indicating a more intense inflammatory response in untreated animals. These differences were transient and were no longer observed at later time points. Therefore, the findings suggest that HA-based hydrogels, particularly when combined with silver, promote wound healing during the initial phase and represent a promising therapeutic alternative for partial-thickness burns.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 3","pages":"e20250641"},"PeriodicalIF":1.2,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148683274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated how fructooligosaccharide (FOS) treatment affects microbial fermentation, intestinal function, inflammation, and hepatic bile acid synthesis in G. lamblia-infected gerbils. Gerbils were divided into four groups: uninfected control, infected control, uninfected and FOS-treated, and infected and FOS-treated. Cecal short-chain fatty acids (SCFAs), intestinal disaccharidase activities, serum and intestinal cytokines, and hepatic expression of Cyp7a1 and Cyp8b1 were analysed. Giardia infection increased cecal acetate, reduced butyrate, elevated serum TNF-α, and increased hepatic Cyp7a1 expression. FOS supplementation increased cecal propionate and other SCFAs and elevated IL-10 levels in serum and intestinal tissue. Notably, FOS reduced intestinal maltase activity regardless of infection status, without affecting lactase activity. Together, these data indicate that giardiasis alters microbial fermentation and inflammatory responses, whereas FOS supplementation primarily promotes a more regulatory immune profile, characterized by increased IL-10 levels, alongside shifts in microbial fermentation, without directly modifying hepatic bile acid-related gene expression. These findings highlight complex diet-microbiota-host interactions during intestinal parasitic infection and support further mechanistic studies.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 3","pages":"e20250973"},"PeriodicalIF":1.2,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148683323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, available population estimates lack methodological transparency, undermining their application in public policies and conservation strategies. This study aims to rigorously estimate the number of inhabitants living within the limits of the Atlantic Forest Biome, considering two official territorial boundaries: the area defined by the Atlantic Forest Law, 2006 and the domain defined by Brazilian Institute of Geography and Statistics, 2019. Using data from the 2022 Demographic Census and a standardized criterion for municipal inclusion, results indicate that approximately 57% of the Brazilian population resides within the Atlantic Forest Biome. This figure is lower than those reported in the literature but still represents a significant number, considering the biome covers approximately 15% of Brazil's continental territory.
