UN CORAL CENTENARI MOR EN POCS DIES<\/h2>\n<p>A la Cima, a Castell-Platja d\u2019Aro, SILMAR ha detectat la mort accelerada d\u2019una col\u00f2nia de Cladocora caespitosa, d\u2019edat estimada superior als 150 anys, en menys d\u2019una setmana. Segles de vida perduts en pocs dies. Les anomalies t\u00e8rmiques afavoreixen la necrosi d\u2019aquest coral mediterrani i poden alterar-ne la microbiota, amb un possible paper dels pat\u00f2gens oportunistes. La causa concreta d\u2019aquest episodi requereix an\u00e0lisis. El seguiment de temperatura i teixit viu \u00e9s essencial per documentar la p\u00e8rdua i orientar la conservaci\u00f3.<\/p>\n<p><a href=\"https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0070820\" target=\"_blank\" rel=\"noopener\"><strong>+Info: Calor i mortalitat coral\u00b7lina<\/strong><\/a><\/p>\n<h2>III.

Amb el seu bec raspa el substrat per alimentar-se: si augmenta la seva abund\u00e0ncia, pot modificar les comunitats d\u2019algues i les relacions amb altres herb\u00edvors. Una observaci\u00f3 no prova una poblaci\u00f3 establerta ni un impacte local.

La reproducci\u00f3 sexual pot aportar diversitat gen\u00e8tica i afavorir la dispersi\u00f3.
