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...

Host phenology is an important determinant of the microbial community, yet how it shapes the evolution and function of endophytic fungi in native plants of the Cerrado remains poorly understood. We investigated cultivable foliar fungal communities in Connarus suberosus (evergreen) and Diospyros lasiocalyx (deciduous) using an integrative approach. A total of 365 isolates were obtained, and most belonged to the genus Diaporthe...

Knowledge of owls' vocal activity is essential for understanding their responses to environmental change. We investigated patterns of vocalizations in the tropical screech-owl ( Megascops choliba ) and the spectacled owl ( Pulsatrix perspicillata ) in forest patches in the far north of the Atlantic Forest, Brazil, from September 2022 to January 2023. We sampled 88 sites in 11 patches using autonomous recording units over three...

The objective of this study was to evaluate the impact of Terminalia catappa powder consumption on biochemical, morphometric, cardiovascular risk, and hepatic markers in aged Wistar rats. Three groups were formed (n = 10): the control group (CG) was treated with distilled water, and the P500 and P1000 groups were treated with 500 and 1000 mg/kg of Terminalia catappa powder, respectively. Animal body weight and food intake were...

The purpose of this research was to assess the effectiveness of a combination of monoterpenes (thymol and carvacrol) in treating juvenile Nile tilapia ( Oreochromis niloticus ) infected with Edwardsiella tarda as a potential substitute for the antibiotic oxytetracycline. The study utilised different concentrations of the monoterpenes blend (MTs): 0.4, 0.6 and 0.8 g kg −1 of feed. A negative control group received a diet withou...

Aquaculture is a rapidly growing industry that supplies fish for global consumption. However, the intensive production practices have resulted in disease outbreaks, largely driven by the misuse of antibiotics. Natural alternatives, such as monoterpenes, which are biocompounds derived from essential oils obtained from plants like thyme and oregano, are being investigated for their antimicrobial properties. Research has shown th...

Floods and fires are part of the ecological regime in many wetlands, yet their interconnectedness is poorly explored. Climate extremes, such as droughts and heatwaves, are increasing fire frequency and intensity, while changing rainfall patterns make floods more unpredictable. These events shape wetland physiognomy, species composition, and functioning. Different wetlands experience varying fire exposure; seasonally inundated...

Purpose This study examined the effect of 3 and 6 weeks of intensity domain-based exercise training on $${\dot{\text{V}}\text{O}}_{{2}}$$ V ˙ O 2 kinetics changes and their relationship with indices of performance. Methods Eighty-four young healthy participants (42 M, 42 F) were randomly assigned to six groups (14 participants each, age and sex-matched) consisting of: continuous cycling in the (1) moderate (MOD)-, (2) lower he...
