Avui hem rebut la visita de l\u2019alumnat de 2n de Batxillerat de l\u2019Institut Marti Dot <\/strong>de Sant Feliu de Llobregat per fer un estudi limnol\u00f2gic de la Riera de Vallvidrera<\/a> a la zona de Can Castellv\u00ed.<\/p>\n

\"\"Primer han contextualitzat l\u2019\u00e0rea a estudiar calculant la superf\u00edcie de la conca hidrogr\u00e0fica i esbrinant de quins materials geol\u00f2gics est\u00e0 formada. Despr\u00e9s s\u2019han organitzat en grups de treball i han revisat el material necessari per dur a terme l\u2019estudi de camp, tenint en compte tant els par\u00e0metres fisicoqu\u00edmics (bi\u00f2top) com els referents a la biodiversitat (biocenosi), per poder determinar la qualitat de l\u2019aigua de la riera.<\/p>\n

Un cop a la riera han registrat diverses dades in situ<\/em> (temperatures, fond\u00e0ria, velocitat, transpar\u00e8ncia, olor, granulometria…) i han agafat mostres d\u2019aigua per fer l\u2019an\u00e0lisi al laboratori. Tamb\u00e9 han valorat l\u2019estat de conservaci\u00f3 de la vegetaci\u00f3 del bosc de ribera. I finalment s\u2019han dedicat a capturar macroinvertebrats aqu\u00e0tics que posteriorment farien servir com a bioindicadors. Han sigut ca\u00e7adors aplicats i han aconseguit atrapar una bona diversitat d\u2019organismes com ef\u00edmeres, espiadimonis, cargols aqu\u00e0tics i sabaters. Incl\u00fas han enxampat un parell de barbs cua roja.<\/p>\n

\"\" Al laboratori han pogut acabar de calcular par\u00e0metres com la duresa, conductivitat, mineralitzaci\u00f3, concentraci\u00f3 de nitrits i fosfats, pH i oxigen dissolt amb l\u2019ajuda dels kits de valoraci\u00f3 del Projecte Rius<\/a>. Han estudiat els macroinvertebrats capturats amb l\u2019ajut de lupes binoculars i fitxes identificatives per determinar el seu \u00edndex biol\u00f2gic. Amb tota aquesta informaci\u00f3\u00a0 han determinat la qualitat de l\u2019aigua en base al protocol IBMWPC, que ha donat un resultat deficient. Per acabar s\u2019han tornat a alliberar sans i estalvis tots els animals capturats al seu h\u00e0bitat, on seguiran el seu cicle vital.<\/p>\n

Felicitats, han sigut un grup molt aplicat i que tamb\u00e9 ha col\u00b7laborat en recollir la brossa que han trobat a\u00a0 la riera.<\/p>\n","protected":false},"excerpt":{"rendered":"
