Prosopis juliflora was introduced to the Brazilian semi-arid region as a forage and firewood plant and spontaneously dispersed to valley areas and now forms almost pure stands in more than 500,000 ha of the region. Since eradication is not being considered, studies on the advantages and disadvantages are necessary. One of the potential advantages is the capability of symbiotically fixing atmospheric N 2 . We determined P. juli...

Dry stacking has emerged as a safer alternative to conventional tailings dams for gold tailings (GT) disposal. Despite growing interest in mine tailings stabilization, much research has focused on conventional binders or alkali-activated binders (AABs) using the two-part method. However, studies on one-part AABs for filtered GT in dry stacking applications remain scarce. This study evaluates the unconfined compressive strength...

The introduction of pines in Southern America to supply the wood industry has promoted interactions with native fauna, including the black-horned capuchin ( Sapajus nigritus [Goldfuss, 1809]). In southern Brazil, this species feeds on pine sap, causing significant economic losses. We used the maximum entropy algorithm (MaxEnt) to model the current and future potential distribution of S. nigritus under different climate change...

This study aims to provide an integrated assessment of recombinant protein bioprocessing by combining technological maturity frameworks (TRL/BRL) with environmental sustainability indicators. A structured literature-based analysis was conducted, covering recent advances in bioprocess engineering, including precision fermentation, artificial intelligence-assisted control, and sustainability assessment tools such as life cycle a...

Mercury (Hg), a highly toxic metal, continues to be widely used in artisanal and small-scale gold mining (ASGM), particularly in the Amazon region. Its improper use and disposal contribute to the contamination of aquatic ecosystems, impacting fish and the human populations that rely on them for food. This study evaluated mercury contamination, measuring total mercury (THg) in the Peixoto de Azevedo River Basin, located in the...

Invasive alien species can significantly impact the environment, public health, and food production. Identifying high-risk areas is essential for implementing preventive measures, especially for species with several traits linked to invasive behavior, such as Spodoptera litura (F.). This study aimed to predict the potential global distribution of S. litura and assess its implications for five major crops in Brazil. Climatic su...
