AI Article Synopsis
- The study compares the effectiveness of hand-nets versus automatic traps for capturing diurnally active mosquitoes during disease outbreaks in Brazil, specifically in Vassununga State Park.
- Over 27 days, researchers collected 1,555 mosquitoes from both the ground and canopy, yielding a variety of taxa with the hand-net showing the highest diversity and abundance.
- Despite some limitations with collector biases, the hand-net remains the preferred method for capturing arbovirus vectors, particularly for yellow fever, during the daytime.
Article Abstract
The hand-net is the standard method for capturing mosquitoes with sylvatic diurnal activity in disease outbreaks in Brazil. However, occupational risks and biases related to the collectors' abilities and attractiveness are important limitations. In this study, we compared hand-nets with automatic traps (CDC) associated to CO and BG-Lure in the Vassununga State Park, a Brazilian Savanna protection area. The collections carried out over 27 days on the ground and the forest canopy. A total of 1555 mosquitoes were obtained in 20 taxa. The diversity index ranged between 1.12 and 1.79 and the dominance index from 0.22 to 0.40. The dominant species on the ground was (46.0%), and in the canopy, (31.9%). was rare ( = 2). The hand-net resulted in the greatest diversity and abundance of species in both strata, followed by the traps associated with CO. A low degree of similarity was observed between the hand-net on the ground compared to the other capture methods. The use of BG-Lure alone resulted in a low number of specimens. In conclusion, the hand-net is still the method of choice for collecting arbovirus vectors in the diurnal period, especially yellow fever vectors.

Introduction: The Bovine Viral Diarrhea Virus 1 (BVDV1) and HoBi-like virus (BVDV3), both within the same genus, share genomic homology and exhibit low antigenic cross-reactivity despite presenting similar clinical manifestations. In 2021, a bovine respiratory disease complex (BRDC) outbreak on two cattle farms in the Inner Mongolia Autonomous Region of China resulted in ten fatalities.
Methods: Metagenomic and metatranscriptomic analyses were used to identify viral agents, including a co-infection case.

Water availability and light during the dry and rainy seasons in the Cerrado may influence plants' stomatal movement and the entry of CO for organic synthesis, which is the main electron drain. A lower stomatal conductance may contribute to the energy accumulated in the chloroplasts being directed towards the synthesis of compounds, which contributes to the activity of antioxidant enzymes to neutralize reactive oxygen species. is a characteristic Cerrado species, and it is often recommended for recovering degraded areas.

Article Synopsis
- - A new bacterial strain, identified as Comamonas sp., has been isolated from the Brazilian Cerrado biome and is classified as a novel species within the Comamonas genus, proposed to be named Comamonas brasiliensis nov.
- - Genetic analyses, including dDDH and ANI, suggested that this strain has a close relationship with Comamonas testosteroni but is distinct enough to be considered a separate species.
- - The strain is characterized as a Gram-negative, non-spore-forming, motile bacterium, with optimal growth conditions at 30°C and a pH range of 5-8, along with unique fatty acid profiles related to its metabolism.

Ecological restoration is crucial to counter global ecosystem degradation. The Brazilian Pampa, home to significant biodiversity, has been overlooked in research and conservation policies. This study involved a comprehensive literature review of 26 articles on restoration in the Brazilian Pampa, including 17 on grasslands and nine on forests, to understand the current state of knowledge on the subject.
