Abstract
El Simposio Internacional "Ecohydraulics" es, con diferencia, el evento de máximo nivel en el ámbito de estudio en que el grupo de investigación Hidrobiología. Es un foro internacional sobre la ciencia de la ecología y la hidráulica, así como la aplicación de los principales avances en la gestión. Con más de 200 comunicaciones, entendemos que a pesar de no tener ISSN, esta actividad está de sobra justificada como relevante a efectos del Plan de Calidad. http://www.ntnu.edu/ecohydraulics2014/ecohydraulics-2014#.VXFdY9KqpBc Resumen: Water temperature is a central issue in freshwater ecology because it influences on physical, chemical and biological processes and, therefore, on organisms that live all the time or part of this in water. Therefore, climate change might drive the availability of suitable habitat for many fish species including brown trout. This paper deals with the mechanics of the effects of Climate Change on thermal performance in two streams in the centre of the Iberian Peninsula (Duero basin) and its consequences on brown trout (Salmo trutta) distribution. Water temperature data were collected by means of 11 thermographs located along the altitudinal gradient of the trout range in the streams. Trout abundance was studied using electrofishing samplings conducted at 37 sites. A high resolution spatio-temporal model was developed to reconstruct the temperature regime of the streams in the past and to simulate its behaviour in the future, using air temperature as the independent variable. The thermal behaviour simulations of the streams were based on the most recent climate change scenarios used in the 5th Assessment Report of the Intergovernmental Panel on Climate Change. According to observations in this study, climate warming might drive a retraction up to 56% of the current brown trout thermal habitat in the studied streams.
