We fit ongoing 40+-year mark-recapture databases from the thriving southern right whale (SRW), , and highly endangered North Atlantic right whale (NARW), , to candidate survival models to estimate their life spans. Median life span for SRW was 73.4 years, with 10% of individuals surviving past 131.8 years. NARW life spans were likely anthropogenically shortened, with a median life span of just 22.3 years, and 10% of individuals living past 47.2 years. In the context of extreme longevity recently documented in other whale species, we suggest that all balaenid and perhaps most great whales have an unrecognized potential for great longevity that has been masked by the demographic disruptions of industrial whaling. This unrecognized longevity has profound implication for basic biology and conservation of whales.
我们将来自数量不断增长的南露脊鲸(SRW)以及极度濒危的北大西洋露脊鲸(NARW)持续40多年的标记重捕数据库,与候选生存模型进行拟合,以估计它们的寿命。南露脊鲸的平均寿命为73.4岁,10%的个体存活超过131.8岁。北大西洋露脊鲸的寿命可能因人为因素而缩短,平均寿命仅为22.3岁,10%的个体存活超过47.2岁。鉴于最近在其他鲸鱼物种中记录到的极端长寿情况,我们认为所有露脊鲸科以及可能大多数须鲸都具有未被认识到的长寿潜力,这种潜力因工业捕鲸造成的种群结构破坏而被掩盖。这种未被认识到的长寿对鲸鱼的基础生物学和保护具有深远意义。
