Essential oil of ocimum gratissimum as a natural fungicide against pathogenic fungi of fruit crops and molecular docking studiesNARA Subscribed
Fungal diseases in fruit crops compromise productivity even when synthetic fungicides are applied. However, growing health and environmental concerns have made such products less attractive to consumers. In this context, the present study aimed to extract and characterise the essential oil (EO) from leaves and flowers of African basil ( Ocimum gratissimum L.) by hydrodistillation and to evaluate its bioactivity against the fun...
Biochar-driven shifts in the soil bacterial community structure of degraded semiarid soilsNARA Subscribed
Low biochar rates (5 Mg ha −1 ) increased bacterial richness and diversity in degraded soil. Biochar origin controlled microbial assembly and niche specialization patterns. Sewage-sludge biochar favored stress-tolerant and metal-adapted bacterial taxa. Cashew bagasse biochar enhanced nitrogen cycling and chemoheterotrophic functions. Network complexity peaked at intermediate biochar doses and declined at high rates. Biochar ha...
Inhabiting the host: ectoparasites and Vector-Borne pathogens in Phyllostomidae bats within urban forest fragmentsNARA Subscribed
While bats are known to harbor various viruses and bacteria, their role as hosts for hemoparasites has not been extensively studied. This research investigated the presence of ectoparasites and vector-borne pathogens—including Anaplasmataceae agents, hemoplasmas, apicomplexans, and kinetoplastids—in 74 Phyllostomidae bats sampled from an urban forest fragment in southeastern Brazil. Overall, 31.1% of the bats were infested wit...
Fast adsorption of Mn2+ and Zn2+ on commercial LTA zeolite: kinetics, equilibrium, and preliminary reuse assessmentNARA Subscribed
Commercial LTA-type zeolite was evaluated for the adsorption of Mn 2+ and Zn 2+ from aqueous solutions, with emphasis on the relationship between framework properties and adsorption behavior. Despite its very low BET surface area, the zeolite showed rapid and highly efficient uptake of both metal ions, reaching near-equilibrium within the first minute. Kinetic modeling indicated site-controlled adsorption consistent with pseud...
Isatin–pyridine oxime hybrids as potential reactivators of A-242-inhibited acetylcholinesteraseNARA Subscribed
Three new isatin–pyridine-2-oxime hybrids (AM01–03) were synthesized and experimentally evaluated as reactivators of acetylcholinesterase (AChE) inhibited by a surrogate of the nerve agent A-242, in comparison with their 4-oxime isomers previously reported by our research group. Furthermore, the interactions of these molecules within the AChE/A-242 complex were assessed through docking and molecular dynamics (MD) simulations....
Organomineral fertilization with sewage sludge: heavy metal content in the soil and bioaccumulation in Urochloa brizanthaNARA Subscribed
The use of sewage sludge as biochar or compost in organomineral fertilizers has been investigated as an alternative to mineral fertilizers, as it can maintain crop yields, reduce environmental impacts, and improve soil quality. Therefore, this study aimed to evaluate the efficiency of organomineral fertilizers derived from sewage sludge and lignolytic compounds, formulated through different technologies, on the bioaccumulation...
Viruses from wild plants may emerge as new economically important agricultural pathogens through spillover events. Blainvillea yellow spot virus ( Begomovirus blainvilleae , BlYSV) is a bipartite geminivirus which is ubiquitous in the non-cultivated plant Blainvillea rhomboidea . To better understand the ecological and evolutionary aspects of this virus, we sampled B. rhomboidea in three Brazilian states between 2020 and 2023....
Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120 sites using active search and litter sifting. Native vegetation cover was quantified...
Patterns of resource use in loggerhead turtle (Caretta caretta) from the Southwestern Atlantic OceanNARA Subscribed
The Southwestern Atlantic Ocean (SWAO) is an important feeding and developmental area for loggerhead turtle ( Caretta caretta ). However, long-term patterns of resource use across life stages and sexes remain poorly understood for the species in this region. Here, we used stable isotope analysis (SIA) of sequential layers of carapace scutes to investigate resource use of loggerhead turtles in the SWAO across life stages and se...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Amazon Dry Season Will Lengthen Under Future ClimateNARA Subscribed
The Amazon rainforest is a key component of the Earth system, regulating regional climate, sustaining high biodiversity and carbon stocks. However, it is threatened by climate and land‐use changes. In recent decades, the region has experienced intensified droughts and heatwaves, trends expected to worsen under future warming. In this study, we assess how the timing, length, and spatial distribution of the dry season across the...

Predictive validation of the repeated low-dose reserpine rodent model of parkinsonismNARA Subscribed
L-DOPA (LD) is the gold-standard treatment of motor symptoms in Parkinson’s disease (PD), conventionally used to prove the predictive value of PD animal models. This study aimed to investigate the predictive validity of an adaptation of the conventional reserpine model of PD: the repeated low-dose reserpine administration in rodents, which promotes progressive motor impairment in catalepsy, vacuous chewing behavior tests, and...
