三、阅读理解
Scientists Dieg Kersting and Cristina Linares have fund that sme cral species are able t recver frm harmful warming events thrugh a unique survival strategy (策略)—knwn as “rejuvenescence(复壮)” —amng crals in the Mediterranean Sea.The findings represent sme rare gd news fr crals arund the wrld,which are facing numerus severe threats—mst ntably,climate change.
“The main threats are climate change,verfishing,pllutin and castal urbanisatin,” Kersting said.“But currently,climate change is prbably the ne causing the mst cral cver declines.Warming stresses crals up t a pint that may cause death.Sme crals bleach (白化) befre dying.Other crals d nt bleach but die directly.” He went n,“Our findings are significant because this survival strategy was nly knwn frm fssil crals that existed hundreds f millins f years ag.It is the first time that it has been fund in a living cral.Thanks t ur findings,we knw nw that sme crals are able t recver,but unfrtunately this is nt enugh in the current climate change cntext.”
Fr their research,Kersting and Linares mnitred 243 clnies f the endangered reef-building cral Cladcra caespitsa(丛生) in Spain’s Clumbretes Islands Marine Reserve ver 16 years,starting in 2002.The mnitring revealed that Cladcra caespitsa in the Mediterranean uses rejuvenescence t cpe with warming events.This prcess invlves the plyps(息肉) — r the individual cral animals in a clny—shrinking inward and abandning their skeletns(骨骼) during warm perids,befre rejuvenating at a later pint.“What happens is that sme plyps in a cral clny—smetimes just ne—reduces cmpletely its dimensins and partially retreats frm its skeletn,” Kersting said.“Once the stressful event is ver,the shrunken r rejuvenated plyp recvers its size and builds up a new skeletn.Eventually,it begins t reprduce itself thrugh budding and begins t cver the dead clny surfaces.”
He cntinued,“The results were very surprising because I started t bserve clnies that were dead years ag,that were shwing living parts many years after their death.”
