Deserts Are Bee Hotspots

犹他州沙漠是蜜蜂的聚集地

As all of you know, today we are keeping faith with the future. I'm about to sign a proclamation that will establish the Grand Staircase–Escalante National Monument."More than 20 years ago, President Bill Clinton stood on the south rim of the Grand Canyon, announcing his intention to set aside nearly two million acres of Utah land. Land that his proclamation said was home to, quote, "many different vegetative communities and numerous types of endemic plants and their pollinators."

“大家都知道,今天我们对未来充满信心。我要签署一项公告,建立宏伟的阶梯-埃斯卡兰特国家纪念碑。” 20多年前,比尔·克林顿总统站在大峡谷的南缘,宣布要在犹他州拨出将近200万英亩的土地。他在公告中说这片土地是“许多不同的植物群落和许多种地方性植物及其传粉者”的家园。

Just how many pollinators was an open question at the time. So, a handful of intrepid entomologists set out, season after season, to observe and classify wild bees in every corner of the monument… and they got 660 of them. "So 660 bees represents about half the species known in Utah, and about one fifth of the species known from the United States." Joseph Wilson, an entomologist at Utah State University involved in the efforts. "So there's a big proportion of the bees known from North America are found in the Grand Staircase National Monument."

究竟有多少传粉者在当时是一个悬而未决的问题。因此,一些勇敢的昆虫学家一季又一季地出发,在纪念碑的每一个角落,观察和分类野生蜜蜂……他们得到了660只。“因此660只蜜蜂代表了犹他州已知物种的一半,以及美国已知物种的1/5。”犹他州立大学的昆虫学家约瑟夫·威尔逊参与了这项研究。“因此,在大阶梯国家纪念碑中发现了大量来自北美的蜜蜂。”

But then, he says, just as they were publishing those big results, his team got word the Trump administration was going to shrink the monument to half its size. So they reanalyzed their data in light of the new maps. And found that the new monument left 84 of the 660 wild bee species outside its bounds. "So what does it mean for these 84 species now that they're no longer in these protected lands? We really don't know."

但后来,他说,就在他们公布这些重大成果时,他的团队得到消息,特朗普政府将把这座纪念碑缩小到原来的一半。所以,他们根据新的地图,重新分析了他们的数据,发现新的纪念碑将660种野生蜜蜂中的84种,留在了它的领地之外。“那么,这84个物种现在已经不在这些受保护的土地上了,这意味着什么呢?”我们真的不知道。

Their analysis—and maps of the monument and its bees—are in the journal PeerJ. [Joseph S. Wilson et al., Reducing protected lands in a hotspot of bee biodiversity: bees of Grand Staircase–Escalante National Monument]"One of our main goals is just to make people aware that this area is a hotspot of bee diversity and that pollinators, including all of these native bees, should probably be considered as management plans for these areas get developed."Just as they were considered in the monument's creation.

他们的分析——以及纪念碑及其蜜蜂的地图——发表在《PeerJ》杂志上。“我们的主要目标之一,就是让人们意识到这个领域,是一个热点的蜜蜂多样性和传粉者,包括所有这些本地蜜蜂,应该被认为是管理这些地方被开发的计划。”就像他们在纪念碑的建造中被考虑的那样。
