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...

The future of how we understand and manage ecosystems largely depends on direct and continuous observations that connect local territories to planetary processes. Latin America (LATAM: Mexico, Central and South America, and the Caribbean) hosts ecosystems critical for regulating global carbon, water, and energy cycles. However, persistent underinvestment in science and technology hampers the long‐term monitoring capacity neede...

Introduction Marine macroalgae are increasingly recognized as promising sources of bioactive compounds for sustainable plant disease management. This study evaluated the anti-phytopathogenic potential of organic extracts from three intertidal macroalgal species, Ulva fasciata , Gracilaria khanjanapajiae , and Sargassum wightii , collected from Thalpe Reef, Sri Lanka. Methods Chloroform, ethyl acetate, and methanol extracts wer...

Aim Elevational gradients are excellent systems to study biodiversity variation, yet the ecosystem functions performed by animals along these gradients are poorly understood. We assessed tropical elevational patterns of ant‐mediated seed removal, insect predation and the phylogenetic diversity of the local ant assemblages performing these functions as well as the effects of climate and productivity. Location Southeast Brazil,...

Air pollution is a critical environmental issue influenced by both natural and anthropogenic sources. We hypothesized that PM 2.5 chemical composition varies spatially due to local anthropogenic sources, soil resuspension, and biomass burning. This study analyzed particulate matter (PM 2.5 ) concentrations and chemical composition (black carbon (BC), elements, and ions) in three locations in Rio de Janeiro state: Gávea (urban...

Over the last decades, climate change biology has become a central field in global science, yet knowledge production and its inclusion in global strategies remain profoundly unequal. Our bibliometric analysis of over 580,000 records shows that ~80% of author affiliations come from Global North institutions, meaning that research agendas, theoretical frameworks, and priorities are still largely shaped outside the regions with t...

The proportion of individuals that are found to have empty stomachs during a survey of a predator population's diet has been used as an indicator of the average individual's state of energy balance and of the degree to which its feeding rate (i.e., its functional response) is saturated with respect to prey availability. As such, the proportion of empty stomachs provides insights into the effects of prey on predators and vice v...

Aim Plant functional traits can influence interaction outcomes between nurse and target plants through a “functional trait match”, which occurs when the traits of nurse plants ameliorate their environment, and target plants possess traits that allow them to benefit from this ameliorated environment. We investigated how the traits of putative nurse species affect interaction outcomes across global drylands and determined the fu...

Dehydroepiandrosterone-sulfate (DHEAS) is the most abundant steroid in humans and some nonhuman primates. This adrenal androgen contributes to immune enhancement, neuroprotection, and reproduction. In humans and apes, DHEAS levels increase before puberty, a phenomenon called adrenarche. However, a postnatal increase in the levels of these hormones is not apparent in cercopithecoids. In marmosets, DHEAS is only synthesized from...
