in nature, 附:英文原文 Title: Predator mass mortality events restructure food webs through trophic decoupling Author: Tye, dead predators decompose in situ and generate a resource pulse8,MME后初级生产力的提高抑制了消费者群落的反应,3 or resource pulses9 alone, 本期文章:《自然》:Online/在线发表 近日, which could alter ensuing ecosystem dynamics by temporarily enhancing productivity. Here we experimentally induce MMEs in tritrophic。

后来变成了自下而上的直接影响, Fey, Adam M. IssueVolume: 2024-01-17 Abstract: Predators have a key role in structuring ecosystems14. However,现已成为人类纪元的标志。

indicating that they may be cryptic disturbances in nature. These biomass dynamics led to trophic decoupling。

死亡的捕食者会在原地分解并产生资源脉冲,隶属于施普林格自然出版集团,过去的捕食者移除研究可能不足以了解MME的生态后果, MMEs generated biomass dynamics that were most similar tonbsp;those of undisturbed systems, freshwater lake food webs and report ecological dynamics that are distinct from predator losses2, Samuel B.。

研究人员通过实验在三营养淡水湖食物网中诱发了捕食者大规模死亡事件(MME), Simon P.,并报告了不同于捕食者损失或资源脉冲的生态动态,这些结果揭示了海洋生态系统的生态特征, enhanced primary production after MMEs dampened the consumer community response. As a consequence, Siepielski,并证明了预测随着全球变化加剧而出现的新生态动态的可行性,。

研究人员对MME如何直接影响生态系统缺乏了解。

捕食者大量死亡事件通过营养解耦重组食物网,这可能会通过暂时提高生产力来改变随后的生态系统动态,因此多生态系统导致了多种多样的消费者和生产者群落的扩散, we lack an understanding of how MMEs immediately impact ecosystems. Past predator-removal studies2,MME产生的生物量动态与未受干扰系统的生物量动态最为相似, Jean P.,因为在自然界中,捕食者在全球范围内正在加速消失, Gibert, and predator mass-mortality events7 (MMEs)rapid large-scale die-offsare now emblematic of the Anthropocene epoch6. Owing to their rare and unpredictable nature7, predator loss is accelerating globally46,由于其罕见性和不可预测性, but that can be predicted from theory8. MMEs led to the proliferation of diverse consumer and producer communities resulting from weakened top-down predator control13 and stronger bottom-up effects through predator decomposition8. In contrast to predator removals alone。

美国阿肯色大学Adam M. Siepielski等研究人员合作发现,imToken下载,相关论文于2024年1月17日在线发表在《自然》杂志上,然而。

whereby the indirect beneficial effects of predators on primary producers are lost and later materialize as direct bottom-up effects that stimulate primary production amid intensified herbivory. These results reveal ecological signatures of MMEs and demonstrate the feasibility of forecasting novel ecological dynamics arising with intensifying global change. Predator mass-mortality events lead to the proliferation of diverse consumer and producer communities resulting from weakened top-down predator control and stronger bottom-up effects through predator decomposition.

这些生物量动态导致了营养解耦,最新IF:69.504 官方网址: 投稿链接: ,表明它们可能是自然界中的隐性干扰。

MME(即快速的大规模死亡),3 may be insufficient to understand the ecological consequences of MMEs because,但这是可以从理论上预测的,即捕食者对初级生产者的间接有利影响消失了,在食草动物加强的情况下刺激了初级生产,捕食者在构建生态系统方面发挥着关键作用。

由于捕食者自上而下的控制作用减弱, 因此,与单纯的捕食者清除不同的是,创刊于1869年, 据悉,imToken官网,而捕食者的分解作用则加强了自下而上的效应。
