espanolEl libro que aqui se presenta tiene aportes fundamentales en la construccion del curriculo en ciencias naturales, una reflexion que dinamiza los elementos de las ciencias y los relaciona con experiencias que muestran el contexto real en la ensenanza y aprendizaje, ademas da una vision fresca del desarrollo en los ultimos anos, de investigaciones formativas y de orden estructural guiadas primero, a la formacion y actualizacion constante del profesorado y segundo, a las reflexiones de la ensenanza de las ciencias. Es importante resaltar que todas las conclusiones que alli suscitan parten de la experiencia de investigadores de diferentes contextos educativos, centralizando los esfuerzos en la actualizacion de un curriculo que tienda a la flexibilizacion y que genere espacios de encuentro real con la ciencia. En este sentido, los capitulos del libro estan organizados en tres partes: tendencias, intersticios y posibilidades, los cuales presenta la exploracion, observacion, planteamientos y definiciones de acciones a desarrollar con el fin de realimentar desafios que se vislumbran en los diversos contextos. EnglishThe book presented here, has fundamental contributions to the construction of the curriculum in natural sciences. A reflection that energizes the elements of science and relates them to experiences that show the real context in teaching and learning, as well as giving a fresh vision of development in recent years, formative and structural research guided first, to the training and constant updating of teachers and second, to the reflections of science teaching. It is important to highlight that all the conclusions that arise there are based on the experience of researchers from different educational contexts, centralizing efforts in updating a curriculum that tends to be more flexible and that generates spaces for real encounters with science. In this sense, the chapters in the book are organized into three parts: trends, interstices and possibilities, which present the evploration, observation, approaches and definitions of actions to be developed in order to respond to challenges that are seen in the various contexts.

espanolLa explotacion minera a cielo abierto conduce a impactos sobre los ecosistemas y sus componentes bioticos, abioticos y sociales, de manera que dejan zonas semiaridas por periodos prolongados de tiempo. Este estudio realizo un inventario con el fin de conocer la diversidad y la riqueza de aves aso-ciadas a tres sitios: Belencito, Chameza y Malsitio (Boyaca, Colombia), en donde se practica mineria a cielo abierto para la obtencion de piedra caliza. Los muestreos se realizaron de septiembre del 2018 a enero del 2019, estableciendo en cada lugar un area de 1000 m2 y nueve puntos de observacion con una distancia de 500 m entre punto y punto. Se identificaron 50 especies de aves, incluyendo algunas migratorias y endemicas. En Belencito se registro la mayor diversidad alfa (q0 = 42 y q1 = 26,6 especies) y en Chameza la menor diversidad (q0 = 17 y q1 = 11,87 especies). EnglishOpen pit mining leads to impacts on ecosystems and their biotic, abiotic and social components, leaving semi-arid areas for prolonged periods of time. This study carried out an inventory in order to under-stand the diversity and richness of birds at three sites: Belencito, Chameza and Malsitio (Boyaca, Colom-bia), where open-pit mining is practiced in order to extract limestone. The samples were obtained from September 2018 to January 2019, and in each location an area of 1000 m2 and nine observation points with a distance of 500 m between each point were established. 50 species of birds were identified, including some migratory and endemic species. In Belencito the highest alpha diversity was recorded (q0 = 42 and q1 = 26.6 species), while in Chameza the lowest diversity was recorded (q0 = 17 and q1 = 11.87 species). portuguesA mineracao a ceu aberto ocasiona impactos nos ecossistemas e seus componentes bioticos, abioti-cos e sociais, deixando zonas semiaridas por periodos prolongados de tempo.
