AUS MARINES<\/strong><\/h1>\n<\/div>
<\/div><\/div><\/div><\/div><\/div>

Les\u00a0aus marines<\/strong>\u00a0agrupen esp\u00e8cies de fam\u00edlies molt diverses que comparteixen un mateix territori, el mar i el litoral. S\u00f3n aus que passen la major part de la seva vida (sovint m\u00e9s del 90 %) en el medi mar\u00ed; tot i aix\u00f2,\u00a0 estan estretament lligades a la terra, lloc on es reuneixen per criar, generalment en col\u00f2nies que poden acollir diversos milers de parelles.<\/p>\n

Les\u00a0aus marines<\/strong>\u00a0posseeixen adaptacions especials per poder sobreviure en el medi aqu\u00e0tic, tals com la seva dieta, basada principalment en animals aqu\u00e0tics (peixos, invertebrats, pl\u00e0ncton\u2026) o el seu cos, adaptat al busseig (plomes hidr\u00f2fobes, capacitat d\u2019apnea, fisonomia apta per a la nataci\u00f3\u2026).<\/p>\n

Avui dia, les\u00a0aus marines<\/strong>\u00a0s\u00f3n considerades el grup d\u2019aus m\u00e9s amena\u00e7at del planeta. Segons la Uni\u00f3 Internacional per a la Conservaci\u00f3 de la Naturalesa (UICN), el 28% de les esp\u00e8cies d\u2019aus marines es troben amena\u00e7ades, i un altre 10% de les esp\u00e8cies estan catalogades com a \u201cQuasi amena\u00e7ades\u201d. La pesca accidental, la contaminaci\u00f3 o la construcci\u00f3 d\u2019infraestructures als mars i al litoral s\u00f3n les principals causes de regressi\u00f3 d\u2019aquestes singulars esp\u00e8cies d\u2019aus.<\/p>\n<\/div>
