有種鳥，生活在被燒毀的森林里

Even animals that thrive in wildfires can’t cope with California’s mega-fires

即使是在野火中茁壯成長(zhǎng)的動(dòng)物，也無(wú)法應(yīng)對(duì)加州的特大火災(zāi)

Northern California’s raging wildfires have become “too extreme” even for certain types of birds that typically thrive in burned out forests, scientists say.

科學(xué)家說(shuō)，即使對(duì)某些鳥類來(lái)說(shuō)，北加州肆虐的野火也變得“太極端”，而這些鳥類通常生活在被燒毀的森林里。

Researchers are trying to understand how the increasingly common megafires, some of which span thousands of hectares, are impacting the surrounding ecosystem.

研究人員正試圖了解越來(lái)越普遍的特大火災(zāi)，其中一些跨越數(shù)千公頃，是如何影響周圍的生態(tài)系統(tǒng)。

Black-backed woodpeckers, which generally favor burned trees where they can enjoy the larvae of wood-boring beetles that live in dead wood, were found to choose the edges of “high severity” burn patches, according to the study’s authors.

研究報(bào)告的作者說(shuō)，黑背啄木鳥通常喜歡被燒毀的樹木，因?yàn)樗鼈兛梢栽谀抢锵硎苌钤谒滥绢^里的蛀木甲蟲的幼蟲。研究發(fā)現(xiàn)，黑背啄木鳥會(huì)選擇生活在“嚴(yán)重”燒毀區(qū)域的邊緣。

The scientists collected data on 118 nests near six large wildfires over a period of eight years, according to the study.

根據(jù)這項(xiàng)研究，科學(xué)家們?cè)?年的時(shí)間里，收集了6處大型野火附近118個(gè)巢穴的數(shù)據(jù)。

“However, it seems that the landscapes created by extra large, intense mega-fires are too extreme,” he explained. “Even fire-associated species need variation in habitat and access to both live and dead trees.”

作者解釋說(shuō)：“然而，似乎特大火災(zāi)造成的后果過(guò)于極端。”“即使是與火災(zāi)有關(guān)的物種，也需要改變棲息地，以及獲得活樹和死樹的途徑。”

The researchers predict that as these new megafires become more common, there will increasingly be more threats to forest wildlife and less and less pyrodiversity.

研究人員預(yù)測(cè)，隨著這些新的特大火災(zāi)變得越來(lái)越普遍，對(duì)森林野生動(dòng)物的威脅將會(huì)越來(lái)越大，而森林的生物多樣性將會(huì)越來(lái)越少。
