TheWater Framework Directive 2000/60/EC proposes macrophytes as biological indicators for assessing the ecological status of rivers. It also indicates the need to establish reference conditions for that indicator in each of the types of surface water bodies. In the Ebro Basin, the macrophyte index IVAM-G has been applied since 2006, a trophic index...

The freshwater red alga Batrachospermum gelatinosum inhabits streams of Europe and North America and has been collected frequently on both continents. A study of this species in North America showed evidence of a glacial refugium in the southeastern United States with little genetic variation throughout its more northern range in eastern North Amer...

The implementation of the Water Framework Directive (2000/60/CE) in the Ebro River Basin and the evaluation of the ecological status of rivers, lakes and wetlands are increasing the knowledge about the distribution and ecology of aquatic organisms, including the red algae (Rhodophyta). In this work we show new data concerning the distribution, habi...

During the implementation of the biological samplings in the CEMAS network (Control of the Status of Surface Water Bodies) in the Ebro River Basin, in application of the Water Framework Directive (period 2006-2010), the presence of the chlorophycean alga Tetrasporidium javanicum M¨obius, 1893 was detected in the middle reaches of Ebro River, in low...

del Agua 2000/60/CE propone a los macrófitos como indicadores biológicos para la evaluación del estado ecológico de los ríos. También establece la necesidad de definir las condiciones de referencia de dicho indicador para cada una de las tipologías de masas de agua superficial. En la Cuenca del Ebro se viene aplicando desde el año 2006 el índice de...

This paper is the first attempt to compile a list of the non-indigenous aquatic invertebrate species currently known to occur in the Ebro River basin (Northeast Spain). A total of 23 exotic aquatic species have been recorded in this area, and one more (the branchiobdellida Xironogiton victoriensis) may also be present in this Iberian basin. Due to...

This paper presents the distribution and the ecological parameters of Didymosphenia geminata in the Ebro River basin (North-East Spain) during the period 2006-2009. The presence of blooms in some rivers in 2009, as in Cinca River in Las Pilas bridge, is reported. D. geminata was found in summer at 24 localities, forming blooms in three of them. It...

New records of Eunapius fragilis (Leidy, 1851) and Ephydatiauviatilis (Linnaeus, 1759) (Porifera, Spongillidae) in the Ebro River Basin (N Spain) This note represents a contribution to the knowledge of the presence of some species of freshwater sponges (Porifera, Spon- gillidae) in the Ebro River Basin. Two species (Eunapius fragilis and Ephydatiau...
