Tracheoesophageal fistula associated with paracoccidioidomicosis

Paracoccidioidomycosis is a systemic fungal disease caused byParacoccidioides brasiliensis, agent geographically distributed to certainareas of Central and South America. The infection by P. brasiliensis hasbeen reported from north Mexico to south Argentina. Paracoccidioidomycosispresents similar clinical findings of many other diseases whatever in acute or chronic scenarios. Chronic pulmonary paracoccidioidomycosis is frequentlymisdiagnosed as malignancy or tuberculosis. The authors present a caseof a 57 year-old man admitted to the hospital due to a chronic consumptivesyndrome. He underwent anti-tuberculous treatment with rifampin, isoniazid andpyrazinamide 1 year ago without resolution of the simptoms. During the clinicalinvestigation, pulmonary paracoccidioidomycosis with tracheoesophagealfistula was diagnosed. The systemic infection was treated with deoxicolate Bamphotericin followed by sulfametoxazole and trimetoprin due to acute renalfunction impairment. The fistula was endoscopically treated; inittialy with theprotection of left main bronchus with a tracheal prosthesis followed by theesophageal fistula’s ostium clipping.A paracoccidioidomicose é uma micose sistêmica causada peloParacoccidioides brasiliensis, que é encontrado em regiões da América doSul e Central, com casos relatados do norte do México ao sul da Argentina.As infecções causadas pelo P. brasiliensis frequentemente mimetizam outrasdoenças.

Especies de Monogenoidea de cíclidos con importancia comercial en la Amazonia peruana

In the Peruvian Amazon, species of the Cichlidae constitute a valuable resource for fisheries and aquaculture activities. Due to the importance of cichlids in this region and the constant interest in conduct studies focused on the biodiversity of monogenoids, the present study aimed to present a checklist of monogenoids from the gills of cichlids with importance in aquaculture in the Peruvian Amazon. Thirteen species of cichlids were analyzed from November 2020 to May 2023 from different water bodies in the Peruvian Amazon. There were identified five species of Gussevia Kohn & Paperna, 1964; eight morphospecies of Gussevia (Gussevia sp. 1 to sp. 8); four species of Sciadicleithrum Kritsky, Thatcher & Boeger, 1989; eight morphospecies of Sciadicleithrum; one species of Biotodomella Morey, Arimuya & Boeger, 2019 and one species of Trinidactylus Hanek, Molnár & Fernando, 1974. Taxonomic studies should continue in order to describe the 16 morpho-species recorded in this investigation, contributing to the knowledge of the biodiversity of monogenoids in the Peruvian Amazon.En la Amazonía peruana, las especies de Cichlidae constituyen un valioso recurso para las actividades pesqueras y acuícolas.

Local hydrological conditions influence tree diversity and composition across the Amazon basin

Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well-drained and potentially dry areas. While these conditions may be expected to influence species distribution, the impacts of local hydrological conditions on tree diversity and composition remain poorly understood at the whole Amazon basin scale. Using a dataset of 443 1-ha non-flooded forest plots distributed across the basin, we investigate how local hydrological conditions influence 1) tree alpha diversity, 2) the community-weighted wood density mean (CWM-wd) – a proxy for hydraulic resistance and 3) tree species composition. We find that the effect of local hydrological conditions on tree diversity depends on climate, being more evident in wetter forests, where diversity increases towards locations with well-drained soils. CWM-wd increased towards better drained soils in Southern and Western Amazonia. Tree species composition changed along local soil hydrological gradients in Central-Eastern, Western and Southern Amazonia, and those changes were correlated with changes in the mean wood density of plots. Our results suggest that local hydrological gradients filter species, influencing the diversity and composition of Amazonian forests. Overall, this study shows that the effect of local hydrological conditions is pervasive, extending over wide Amazonian regions, and reinforces the importance of accounting for local topography and hydrology to better understand the likely response and resilience of forests to increased frequency of extreme climate events and rising temperatures

estudos artísticos

A revista Gama, Estudos Artísticos estabeleceu-se como um instrumento para a disseminação do conhecimento em torno da arte e da cultura numa perspetiva que se crê inovadora, e que nos caracteriza: estudar arte e artistas através do olhar formado e privilegiado dos companheiros de profissão. Artistas estudam outros artistas. A revista Gama pertence assim a um projeto de resistência: resistência ao centrismo do artworld, ao esmagamento pelos discursos dominantes, às lógicas de reprodução da legitimação instituída. Há uma característica que prevalece em todos os 28 artigos reunidos na presente edição: a reflexão informada sobre autores e obras de arte, que propõe novas leituras e novas redes de conhecimento. Todas juntas constituem um tecido que descobre sentidos, na sua integração global na nova paisagem cultural.info:eu-repo/semantics/publishedVersio

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Geography and ecology shape the phylogenetic composition of Amazonian tree communities

Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location: Amazonia. Taxon: Angiosperms (Magnoliids; Monocots; Eudicots). Methods: Data for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran\u27s eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny. Results: In the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R$^{2}$ = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R$^{2}$ = 28%). A greater number of lineages were significant indicators of geographic regions than forest types. Main Conclusion: Numerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types
