Molecular characterization of extended-spectrum β-lactamases-producing Escherichia coli isolated from patients with bacteremiaNARA Subscribed
Bacteremia is a major health problem that affects millions of people worldwide. E. coli is one of the main pathogens associated with bacteremia and its resistance to the antimicrobial drugs, including β-lactams, has significantly increased in recent years. In view of the above, our objective was to determine the antimicrobial resistance profile of 60 E. coli isolates obtained from patients with bacteremia, as well as to charac...
Atta robusta is a narrow endemic leaf-cutting ant restricted to restinga habitats along Brazil’s southeastern coast. Despite its conservation status, little is known about its evolutionary history and genetic structure. Here, we investigate patterns of genetic variation in A. robusta using mitochondrial (COI–IGS–tRNALeu–COII) and nuclear (EF1alpha copy one) DNA markers sampled across its known range. We assess genetic diversit...
Potato yield is highly dependent on phosphorus (P) availability. Although high rates of P fertilizers are commonly applied to potatoes even in high P test soils, the efficiency of these practices is questionable. Foliar P fertilization, particularly during the tuber bulking stage, has emerged as a potential complementary strategy. This study aimed to evaluate whether adjusting the conventional P application rate at planting an...
Leaf herbivory is a ubiquitous ecological interaction that varies significantly in intensity across species, habitats, and biogeographic regions. Although quantification of leaf damage is crucial for understanding many ecological processes, the accuracy and precision of various damage estimation methods used by researchers, including visual estimation, digital image analysis, and artificial intelligence, have not been evaluate...
The sustainable supply of n-3 long-chain polyunsaturated fatty acids ( n -3 LC-PUFA) remains a major challenge for global aquaculture. Although plant oils, microalgae, genetically modified crops, insects, krill, and fish by-products have been explored as alternative sources, none currently provides a stand-alone solution for meeting the growing demand of n -3 LC-PUFA in aquafeeds’ production. Here, we present marine gammarids...
Soil property controls on plasticiser, antioxidant and UV absorber additive degradation across a global soil gradientNARA Subscribed
Additives in agricultural plastics can leach into the surrounding soil during use or improper disposal. Their subsequent degradation rates directly regulate whether they persist and accumulate to levels with ecotoxicological effects or are rendered benign. However, which soil properties primarily regulate the degradation of additives remains unclear (e.g. soil carbon, pH, available nutrients, microbial biomass and community st...
