The Paraguayan hairy dwarf porcupine ( Coendou spinosus , Cuvier, 1823) is a rodent species (Rodentia, Erethizontidae) widely distributed in the Brazilian Atlantic forest. However, little is known about their viral diversity. In this study, we aimed to evaluate, using high-throughput sequencing (HTS), the virome of the feces of seven healthy adult free-living porcupines from Silva Jardim, Rio de Janeiro, Brazil. Total viral nu...

Urban stormwater runoff is an important pathway for transporting microplastics (MPs) from urban environments to marine ecosystems. However, studies investigating how socio-spatial characteristics influence MP abundance and composition remain scarce, particularly in South America. This study evaluated the influence of population density and land use on MP abundance and morphology in stormwater runoff in the coastal zone of Fort...

Rhodococcus equi is an important bacterium that affects foals up to six months of age, especially those that are immunocompromised. The main manifestation is pyogranulomatous pneumonia; nevertheless, extrapulmonary lesions have not only been reported, but are not uncommon, including arthritis and osteomyelitis. Despite the widespread occurrence of rhodococcosis, the macro- and microscopic lesions in the musculoskeletal system...

The anesthetic management of female dogs with mammary neoplasia, usually classified as ASA II and undergoing invasive procedures such as mastectomy and ovariohysterectomy, requires effective sedation and anesthetic stability due to the increased anesthetic risk associated with advanced age and underlying disease. In this context, this study aimed to evaluate the sedative effects and reduction in anesthetic requirements of a fu...

Tachigali vulgaris has potential for energy purposes in the Amazon, but the relationship between several silvicultural factors and wood quality requires further investigation. This study evaluated the variation in the apparent density of T. vulgaris wood in two pure plantations in the Amazon. The tested factors were diameter, height, stem forking, fertilization, and soil texture. Two 11-year-old trial plantations located on ye...

Background Central nervous system (CNS) candidiasis is a rare but life-threatening complication of invasive candidiasis. However, current knowledge derives mainly from isolated case reports, and no comprehensive synthesis has been previously performed. Methods We conducted a systematic review of published cases of CNS candidiasis. PubMed and Embase were searched without language or date restrictions. Eligible cases required mi...

Sandy beaches are dynamic ecotones where beach-profile morphology, sediment properties, and allochthonous organic subsidies interact with intertidal benthic communities. We assessed seasonal variation in beach morphology, sediment granulometry, beach-cast macroalgal wrack, and associated macrofaunal assemblages at two tropical sandy beaches on the central Brazilian coast: Putiri Beach and Fifteen Beach. Both beaches were class...

Urbanization is a leading driver of change in freshwater ecosystems worldwide, directly altering biodiversity and ecosystem services. We systematically reviewed how urban ecology examines freshwater ecosystems and organism–environment relationships. We searched databases and synthesized evidence to examine associations among environments, biological groups, and urbanization. We also applied structural topic modeling to identif...

Aims Silicate rock powders can enhance nutrient availability through rhizosphere-mediated mineral weathering. Although organic acids mediate this process, how soil fertility shapes their interactions with rhizosphere microbial communities and nutrient release remains poorly understood. He, we evaluated how contrasting soil fertility influences rhizosphere organic acids, microbial communities, and nutrient release from silicate...
