Download Download PDF. Translate PDF. The laboratory of stream ecology, at the University of the Basque Country, has been researching streams from an ecosystem perspective, including both structural and functional properties. Here we review the research done so far. Basque streams running to the Atlantic Ocean are short, steep, and flashy, and tend to show large spa- tial variations as a result of changes in geology and soil use. Where they exist, riparian forests limit the growth of primary pro- ducers and are a source of coarse particulate organic matter, an important food resource for consumers.

The trophic structure of benthic macroinvertebrate communities changes downstream with resource abundance, although temporal variations of both resources and consumers why cant i understand when i read not coupled. Gut content analyses show the hsqldb properties file example of some species to change with instar deve- lopment, and thus, warn against the indiscriminate assignation of trophic categories.

Floods are important disturbances, affec- ting primary producers, consumers, and ecosystem processes. Other important disturbances are changes in riparian vegetation, which can profoundly affect the food resources of stream communities. This basic knowledge has been used to develop new tools to assess stream functional impairment, based in two pivotal functions: litter breakdown and whole stream metabolism.

Both eutrophication and changes in riparian vegetation affect the use of leaf litter, and thus impact stream functioning making litter breakdown a promising tool for stream monitoring. On the other hand, whole stream metabolism is affected by many human impacts, and can be measured continuously in modern gauging stations, thus allowing for almost real-time monitoring of ecosystem functioning.

We hope these and other functional properties will be built into routine monitoring schemes, which will therefore what is a healthy break in a relationship at both the structural and functional sides of stream ecosystems. Keywords: Basque streams, structural and functional properties, leaf breakdown and metabolism processes.

RESUMEN La mayor parte de los trabajos sobre ecología de ríos se ha centrado en características estructurales, y se ha dedicado menos esfuerzo a estudiar los atributos funcionales de los ecosistemas fluviales. El laboratorio de ecología de ríos, en la Universidad del País Vasco, ha estado estudiando arroyos desde una perspectiva ecosistémica, incluyendo propiedades estructurales y funcio- nales, y mostramos aquí una revisión de los trabajos llevados a cabo. Las riadas son perturbaciones importantes que afectan tanto a productores primarios como a consumido- res, o a procesos a nivel de ecosistema.

Otras perturbaciones importantes son los cambios en la vegetación riparia, que pueden afectar profundamente los recursos alimentarios de las comunidades fluviales. Tanto la eutrofización como los cambios en la vegetación de ribera afectan el uso de la hoja- rasca y, por tanto, impactan en el funcionamiento del ecosistema, lo que hace de la descomposición de hojarasca una herra- mienta prometedora para el seguimiento de los ríos. Por otra parte, el metabolismo del ecosistema fluvial es afectado por muchos impactos humanos, y puede ser medido en continuo en estaciones de aforo modernas, lo que permite seguir el funciona- miento del ecosistema casi a tiempo real.

Mass-balance of water top and dissolved phosphorus bottom along the Agüera stream on July 10, Numbers are sampling sites along the stream axis; vertical bars from the top represent inputs from the tributaries, and arrows on the bottom represent the net balance of other inputs and outputs. In the case of water, inputs are mainly groundwater. In the case of phospho- rus, most inputs come from sewers, and outputs reflect in-stream nutrient withdrawal self-purification. Note the differences bet- ween both variables, and the important retention of phosphorus in the mid reaches of the Agüera stream.
