Abstract
Gran parte de la superficie de la Tierra está cubierta por montañas, que albergan una gran proporción de la biodiversidad, incluso más de lo esperado para un área determinada. Podemos acotar, más en sintonía con nuestro estudio, las denominadas zonas de alta montaña, que comprenden una serie de territorios de distribución mundial presentes en ambos hemisferios, se encuentran situados por encima del límite forestal, una barrera climática a partir de la cual solo pueden subsistir determinados ecosistemas vegetales no arbóreos, adaptados a factores ambientales extremos. Uno de los factores más limitantes de la vida vegetal de estas zonas son las bajas temperaturas, ya que además de producir daños por deshidratación o por congelación del agua en los tejidos de las plantas, limita la energía disponible para su desarrollo y reproducción. El capítulo I responde a preguntas sobre los patrones térmico-climáticos que adopta la vegetación, así como sus consecuencias ecológicas y las alteraciones en los patrones climatológicos asociados al cambio global, buscando las causas por las que este tipo de vegetación es sensible a los cambios ambientales. Por tanto, es un objetivo clave conocer la influencia del microclima en el desarrollo y crecimiento de la vegetación y aportar datos relacionados con la integral térmica vegetativa...
Much of the Earth's surface is covered by mountains, which are home to a large proportion of biodiversity, even more than expected for any given area. We can delimit, more in tune with our study, the so-called high mountain areas, which include a series of territories with a global distribution present in both hemispheres, located above the timberline, a climatic barrier from which only subsist certain non-tree plant ecosystems. One of the most limiting factors for plant life in these areas is low temperatures, in addition to produce damages by dehydration or freezing of water in plant tissues; it limits the energy available for their development and reproduction. Chapter I answer questions about the thermal-climatic patterns of vegetation, as well as its ecological consequences and changes in weather patterns associated with global change, looking for the reasons why this type of vegetation is sensitive to environmental changes. Therefore, it is a key objective to know the influence of the microclimate on the development and growth of vegetation and to provide data related to the vegetative thermal integral...
