Mechanisms for marine ecological protection and recovery, including area-based conservation tools like ‘Marine Protected Areas’ (MPAs) are necessary tools to reach the Aichi Target or the forthcoming 30x30 target set by the Kunming-Montreal Biodiversity Framework. However, full ecosystem recovery takes years to manifest and the idea that MPA protection alone will foster human well-being is frequently contradicted by socio-econ...
Anthropogenic-driven environmental changes are pushing species to the limits of their habitats. More often species are restricted to relic or suboptimal habitats that present the minimum requirements to sustain species populations. In this scenario of accelerated environmental change and biodiversity loss, is fundamental to understand why species can survive in such suboptimal conditions. In this study, we show how the Tenerif...
A global analysis of field body temperatures of active squamates in relation to climate and behaviourNARA Subscribed
Aim Squamate fitness is affected by body temperature, which in turn is influenced by environmental temperatures and, in many species, by exposure to solar radiation. The biophysical drivers of body temperature have been widely studied, but we lack an integrative synthesis of actual body temperatures experienced in the field, and their relationships to environmental temperatures, across phylogeny, behaviour and climate. Locatio...
Spent coffee grounds as feedstock for the production of biosurfactants and the improved recovery of melanoidinsNARA Subscribed
Spent coffee grounds (SCG) are wastes generated in high amounts worldwide. Their composition makes them a promising feedstock for biotechnological processes. Here we show that the production of the biosurfactant surfactin by submerged culture of a Bacillus subtilis strain growing on SCG is possible, reaching concentrations up to 8.8 mg/L when using SCG at 8.3 g/L in the medium. In addition, we report a synergy between the prod...
Environmental impact assessment of nanofluids containing mixtures of surfactants and silica nanoparticlesNARA Subscribed
Due to widespread use of nanoparticles in surfactant-based formulations, their release into the environment and wastewater is unavoidable and toxic for biota and/or wastewater treatment processes. Because of concerns over the environmental impacts of nanofluids, studies of the fate and environmental impacts, hazards, and toxicities of nanoparticles are beginning. However, interactions between nanoparticles and surfactants and...
