Editorial: The Science of Citizen Science Evolves
Podeu consultar el llibre complet a: http://hdl.handle.net/2445/173349Citizen science broadly refers to the active engagement of the general public in scientific research tasks. Citizen science is a growing practice in which scientists and citizens collaborate to produce new knowledge for science and society. Although citizen science has been around for centuries, the term citizen science was coined in the 1990s and has gained popularity since then. Recognition of citizen science is growing in the fields of science, policy, and education and in wider society. It is establishing itself as a field of research and a field of practice, increasing the need for overarching insights, standards, vocabulary, and guidelines. In this editorial chapter we outline how this book is providing an overview of the field of citizen science
Response of bats and nocturnal insects to urban green areas in Europe
Animal biodiversity in cities is generally expected to be uniformly reduced, but recent studies show that this is modulated by the composition and configuration of Urban Green Areas (UGAs). UGAs represent a heterogeneous network of vegetated spaces in urban settings that have repeatedly shown to support a significant part of native diurnal animal biodiversity. However, nocturnal taxa have so far been understudied, constraining our understanding of the role of UGAs on maintaining ecological connectivity and enhancing overall biodiversity. We present a well-replicated multi-city study on the factors driving bat and nocturnal insect biodiversity in three European cities. To achieve this, we sampled bats with ultrasound recorders and flying insects with light traps during the summer of 2018. Results showed a greater abundance and diversity of bats and nocturnal insects in the city of Zurich, followed by Antwerp and Paris. We identified artificial lighting in the UGA to lower bat diversity by probably filtering out light-sensitive species. We also found a negative correlation between both bat activity and diversity and insect abundance, suggesting a top-down control. An in-depth analysis of the Zurich data revealed divergent responses of the nocturnal fauna to landscape variables, while pointing out a bottom-up control of insect diversity on bats. Thus, to effectively preserve biodiversity in urban environments, UGAs management decisions should take into account the combined ecological needs of bats and nocturnal insects and consider the specific spatial topology of UGAs in each city.info:eu-repo/semantics/publishedVersio
SISTEMA DE PROCEDIMIENTOS POR PROYECTOS PARA EL PROCESO DE ENSEÑANZA-APRENDIZAJE DE LA COMPRENSIÓN LECTORA EN LENGUAS EXTRANJERAS CON FINES ACADÉMICOS
The dynamics of the teaching-learning process of reading comprehension in foreign languages for academic purposes in Cuban universities leads to search for didactic alternatives for its improvement. Hence, in the present work, it is proposed a system of procedures through the method of project work, which allowed students to process textual information from different sources in an effective way and communicate this knowledge in diverse formative contexts. It was also carried out a partial exemplification of this contribution, whose process of evaluation corroborated the feasibility and relevancy for its application, as well as its possibility of adaptation and implementation in other subjects of the English Language Discipline and other foreign languages studied in Cuban Higher Education. In this sense, the qualitative interpretation of the reached results showed an evolution in the teaching-learning process object of investigation, strengthening this way, the apprentices’ level of access to information through the analysis and contextualization, in order to achieve a better academic and professional formation.
La dinámica del proceso de enseñanza-aprendizaje de la comprensión lectora en lenguas extranjeras con fines académicos en las universidades cubanas conlleva a una búsqueda de alternativas didácticas para su perfeccionamiento. Es por ello, que en el presente trabajo se propone un sistema de procedimientos a través del método de trabajo por proyectos, que les permitió a los estudiantes procesar información textual proveniente de diferentes fuentes de manera efectiva y comunicar estos conocimientos en diversos contextos formativos. Se realizó, de igual forma, una ejemplificación parcial de dicho aporte, cuyo proceso evaluativo corroboró la factibilidad y pertinencia para su aplicación, así como su posibilidad de adaptación e implementación en otras asignaturas de la Disciplina Idioma Inglés y otras lenguas extranjeras estudiadas en la Educación Superior en Cuba. En este sentido, la interpretación cualitativa de los resultados alcanzados demostró una evolución en el proceso de enseñanza-aprendizaje objeto de investigación, fortaleciendo así el nivel de acceso a la información de los aprendices mediante el análisis y la contextualización, para lograr una mejor formación académica y profesional
Biomagnetic monitoring of atmospheric pollution: a review of magnetic signatures from biological sensors
Biomagnetic monitoring of atmospheric pollution is a growing application in the field of environmental magnetism. Particulate matter (PM) in atmospheric pollution contains readily measurable concentrations of magnetic minerals. Biological surfaces, exposed to atmospheric pollution, accumulate magnetic particles over time, providing a record of location-specific, time-integrated air quality information. This review summarizes current knowledge of biological material (“sensors”) used for biomagnetic monitoring purposes. Our work addresses the following: the range of magnetic properties reported for lichens, mosses, leaves, bark, trunk wood, insects, crustaceans, mammal and human tissues; their associations with atmospheric pollutant species (PM, NOx, trace elements, PAHs); the pros and cons of biomagnetic monitoring of atmospheric pollution; current challenges for large-scale implementation of biomagnetic monitoring; and future perspectives. A summary table is presented, with the aim of aiding researchers and policy makers in selecting the most suitable biological sensor for their intended biomagnetic monitoring purpose
