Moartea recifelor de corali este o problem\u0103 enorm\u0103 cu care se confrunt\u0103 oceanologii \u00een prezent. O echip\u0103 interna\u021bional\u0103 de cercet\u0103tori de la Universitatea Exeter \u0219i Universitatea Bristol din Marea Britanie, precum \u0219i de la Universitatea James Cook din Australia \u0219i Institutul Australian de \u0218tiin\u021be Marine, sus\u021bin c\u0103 \u201e\u00eembog\u0103\u021birea acustic\u0103\u201d ar putea deveni un instrument valoros \u00een ajutorul restaur\u0103rii recifelor de corali deteriorate.<\/p>\n

\"Acustica<\/p>\n

\u00cen timpul analizei Marii Bariere de Corali din Australia, cercet\u0103torii au instalat difuzoare subacvatice care reproduc \u00eenregistr\u0103ri ale recifelor s\u0103n\u0103toase \u00een zone cu corali mor\u021bi \u0219i au observat de dou\u0103 ori mai multe pe\u0219ti care au venit \u2014 \u0219i au r\u0103mas \u2014 \u00een compara\u021bie cu zonele similare \u00een care nu se reproducea sunetul. \u201ePe\u0219tii sunt esen\u021biali pentru a face ca recifele de corali s\u0103 func\u021bioneze ca ecosisteme s\u0103n\u0103toase\u201d, a spus Tim Gordon de la Universitatea Exeter. \u201eCre\u0219terea popula\u021biei de pe\u0219ti \u00een acest mod poate ajuta la reluarea proceselor de restaurare natural\u0103, contracar\u00e2nd daunele pe care le observ\u0103m pe multe recife de corali din \u00eentreaga lume.\u201d<\/p>\n

Aceast\u0103 nou\u0103 metod\u0103 func\u021bioneaz\u0103 prin reproducerea sunetelor care dispar atunci c\u00e2nd recifele se degradeaz\u0103. \u201eRecifele s\u0103n\u0103toase de corali sunt locuri incredibil de zgomotoase: ciripitul creve\u021bilor, morm\u0103itul \u0219i chicotelile pe\u0219tilor creeaz\u0103 un peisaj sonor biologic str\u0103lucitor. Aceste sunete atrag pe\u0219tii tineri atunci c\u00e2nd caut\u0103 un loc \u00een care s\u0103 se a\u0219eze,\u201d a spus profesorul Steve Simpson de la Universitatea Exeter. \u201eRecifele devin incredibil de t\u0103cute pe m\u0103sur\u0103 ce se degradeaz\u0103, deoarece creve\u021bii \u0219i pe\u0219tii dispar, dar cu ajutorul difuzoarelor care restabile\u0219te acest peisaj sonor pierdut, putem atrage din nou pe\u0219tii tineri.\u201d<\/p>\n

Biologul pe\u0219tilor de la Institutul Australian de \u0218tiin\u021be Marine, doctorul Mark Meekan, a ad\u0103ugat: \u201eDesigur, atragerea pe\u0219tilor c\u0103tre un recif mort nu \u00eel va reveni automat la via\u021b\u0103, dar restaurarea este sus\u021binut\u0103 de pe\u0219ti care cur\u0103\u021b\u0103 reciful \u0219i creeaz\u0103 spa\u021biu pentru cre\u0219terea coralilor.\u201d<\/p>\n

<\/center><\/p>\n

Cercetarea a ar\u0103tat c\u0103 transmiterea sunetului unui reef s\u0103n\u0103tos a dublat num\u0103rul total de pe\u0219ti care ajung \u00een zonele experimentale ale habitatului reef-ului \u0219i a crescut num\u0103rul speciilor prezente cu 50%. Aceast\u0103 diversitate a inclus specii din toate segmentele lan\u021bului trofic \u2014 ierbivore, detritivore, planctofage \u0219i pr\u0103d\u0103tori. Diversele grupuri de pe\u0219ti \u00eendeplinesc func\u021bii diferite \u00een recifele de corali, ceea ce \u00eenseamn\u0103 c\u0103 o popula\u021bie abundent\u0103 \u0219i diversificat\u0103 de pe\u0219ti este un factor important pentru men\u021binerea unui ecosistem s\u0103n\u0103tos.<\/p>\n

\"Acustica<\/p>\n

Profesorul Andy Radford de la Universitatea Bristol a spus: \u201e\u00cembog\u0103\u021birea acustic\u0103 este o metod\u0103 promi\u021b\u0103toare de gestionare la nivel local. \u00cen combina\u021bie cu restaurarea habitatului \u0219i alte m\u0103suri de conservare, recrearea comunit\u0103\u021bilor de pe\u0219ti \u00een acest mod ar putea accelera revitalizarea ecosistemelor. Cu toate acestea, trebuie s\u0103 continu\u0103m s\u0103 ne confrunt\u0103m cu numeroase alte amenin\u021b\u0103ri, inclusiv schimb\u0103rile climatice, pescuitul excesiv \u0219i poluarea apei, pentru a proteja aceste ecosisteme fragile\u201d.<\/p>\n

Domnul Gordon a ad\u0103ugat: \u201eDe\u0219i atragerea unui num\u0103r mai mare de pe\u0219ti nu va salva recifele de corali de una singur\u0103, metodele noi, precum aceasta, ne ofer\u0103 mai multe instrumente \u00een lupta pentru salvarea acestor ecosisteme pre\u021bioase \u0219i vulnerabile. Progrese semnificative la toate nivelurile, de la inova\u021biile \u00een managementul local p\u00e2n\u0103 la ac\u021biunile politice interna\u021bionale, sunt necesare pentru a asigura un viitor mai bun pentru recife \u00een \u00eentreaga lume.\u201d<\/p>\n
