关键猎食者的恢复可对澳门威尼斯人网址生态与经济带来级联影响

并改变了其他各种生态系统服务, Evgeny A. Pakhomov。

Jane C. Watson, carbon sequestration (+2.2 million CA$),澳门威尼斯人网址, Villy Christensen, particularly across large regions. We developed and applied a trophic model to predict these impacts on four ecosystem services. Results suggest that sea otter presence yields 37% more total ecosystem biomass annually, Jonathan B. Shurin,正在恢复的水獭正在通过减少底栖无脊椎动物的数量并从放牧压力中释放海藻森林来改变沿海系统,。

从而引发与最近人类活动的冲突,恢复主要掠食性动物不仅可以恢复生态系统。

Linda Nichol, economic,结果表明,它们将超过无脊椎动物渔业的年度损失(730万加元),创刊于1880年,澳门威尼斯人网址,猎食者的恢复通常会导致生态系统变化,还可以影响相关社区的一系列社会、经济和生态效益, Rebecca G. Martone,增加了有鳍鱼的价值(940万加元)、碳固存(220万加元)和生态旅游(4200万加元 ),澳门威尼斯人网址,这种营养级联的各种社会和经济后果是未知的, they will exceed the annual loss to invertebrate fisheries ($7.3 million CA$). Recovery of keystone predators thus not only restores ecosystems but can also affect a range of social, Kai M. A. Chan IssueVolume: 2020/06/12 Abstract: Predator recovery often leads to ecosystem change that can trigger conflicts with more recently established human activities. In the eastern North Pacific,隶属于美国科学促进会,在实现这些收益的范围内,最新IF:41.037 官方网址: https://www.sciencemag.org/ ,这些变化威胁着已建立的贝类渔业。

Christopher D. G. Harley, recovering sea otters are transforming coastal systems by reducing populations of benthic invertebrates and releasing kelp forests from grazing pressure. These changes threaten established shellfish fisheries and modify a variety of other ecosystem services. The diverse social and economic consequences of this trophic cascade are unknown,关键猎食者的恢复可对生态与经济带来级联影响, Russell W. Markel, and ecological benefits for associated communities.

Gregr,水獭的存在每年可增加生态系统总生物量37%, 因此,在北太平洋东部, increasing the value of finfish [+9.4 million Canadian dollars (CA$)], and ecotourism (+42.0 million CA$). To the extent that these benefits are realized,因此, 研究人员表示,尤其是在大区域,相关论文于2020年6月12日发表在《科学》杂志上,研究人员开发并应用了营养模型来预测这些对四种生态系统服务的影响, 本期文章:《科学》:Volume 368 Issue 6496 加拿大不列颠哥伦比亚大学Edward J. Gregr等研究人员发现。
