Mats Lindegarth, professor vid institutionen f\u00f6r marina vetenskaper vid G\u00f6teborgs universitet, och forskar om musslor, s\u00e4ger att det \u00e4r just den stora spridningen som g\u00f6r \u00e5rets mussels\u00e4ttning unik.<\/p>\n\n\n\n

– Det \u00e4r inte om\u00f6jligt att man kan ha en l\u00e5ngsiktig nedg\u00e5ng av musslor samtidigt som man under enstaka \u00e5r och p\u00e5 enstaka platser f\u00e5r v\u00e4ldigt mycket rekrytering. Nu snackas det om att det varit extremt i \u00e5r. Vi f\u00e5r v\u00e4l se, det h\u00e4r kanske s\u00e4tter sp\u00e5r i populationen under m\u00e5nga \u00e5r fram\u00f6ver men det \u00e4r det som vi hoppas kunna f\u00f6lja upp.<\/p>\n\n\n\n

– \u00c5lgr\u00e4s\u00e4ngarna \u00e4r fullkomligt nedtyngda av sm\u00e5 bl\u00e5musslor. Och livet tycks frodas runt omkring. F\u00f6r mig \u00e4r det \u00f6verraskande. Ska man se det som ett kvitto p\u00e5 att havet b\u00f6rjar \u00e5terh\u00e4mta sig eller \u00e4r det en signal p\u00e5 en obalans med dessa abnorma m\u00e4ngder?<\/p>\n","protected":false},"excerpt":{"rendered":"
