Abstract:
... Quinoa is an Andean grain that is attracting attention worldwide as a high-quality protein-rich food. Nowadays, quinoa foodstuffs are susceptible to adulteration with cheaper cereals. Therefore, there is a need to develop novel methodologies for protein characterization of quinoa. Here, we first developed a matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) ...

Abstract:
... Foodscapes are the sum of all places where food and eating are actualized, as well as the institutional arrangements, discourses, cultural practices, trends and meanings that shape the relationship between individuals and food. However, limited research is available on how the different elements of foodscapes (physical, social, institutional) interact to influence children's and adolescents' eatin ...

Egg capsules had a glossy black or dark brown color, with a subrectangular shape, slightly wider at posterior end than at anterior end. Egg capsules when observed under a stereoscope revealed a finely striated surface. Egg capsul ...

Abstract:
... The bat fauna from the extreme north of Chile is poorly known, principally due to a lack of dedicated surveys. To better assess the diversity of bats there, we conducted acoustic surveys at Arica city and three coastal valleys (Azapa, Lluta and Camarones) in the Arica and Parinacota region, Chile. We obtained 82 acoustic records of the Peale’s free-tailed bat (Nyctinomops aurispinosus) in nine sit ...

Abstract:
... Artisanal and small-scale gold mining (ASGM) is the leading global source of mercury pollution. Efforts to reduce or eliminate mercury use in ASGM have produced limited results, in part because they do not engage the complex socio-technical nature of mercury issues in ASGM. The paper takes a multidisciplinary approach to understand the mercury issue with a socio-technical lens, pairing sampling of ...

AIM: How species respond to climate change is influenced by their sensitivity to climatic conditions (i.e. their climatic niche) and aspects of their adaptive capacity (e.g. their dispersal ability and ecological niche). To date, it is largely unknown whether and how species’ sensitivity to climate change and their adaptive capacity covary. However, understanding this relationship is important to ...
