摘要:

生态网络使我们能够研究生态系统的结构和功能,并深入了解物种的恢复力/稳定性。对这种生态网络的研究通常是集中在有限的特定空间和时间范围内的快照,阻碍了我们感知生态过程的真实动态。根据定义,外来物种具有一些生态策略和特征,使其能够比本地物种更好地竞争(例如没有捕食者,不同的开花期,高生长率等)。植物-传粉者网络为整个生态系统提供了宝贵的服务,外来物种的引入可能对本地网络产生不同的影响(竞争促进、本地物种灭绝等)。虽然科学家们承认网络连接在推动生态系统服务方面的重要性,但将临时网络纳入生态模型仍处于起步阶段。我们建议使用现有的季节性数据来开发一个模拟平台,显示网络的时间性和入侵特征之间的推理。我们的重点只是拿起一些简单的模型来表明,理论上的时间方面发挥作用(不同的灭绝模式),鼓励生态学家参与时间网络。此外,衍生的模拟可以进一步扩展和调整到其他生态问题。

英文摘要:

Ecological networks allow us to study the structure and function of ecosystems and gain insights on species resilience/stability. The study of this ecological networks is usually a snapshop focused in a limited specific range of space and time, prevent us to perceive the real dynamics of ecological processes. By definition, an alien species has some ecological strategies and traits that permit it to compete better than the native species (e.g. absence of predators, different bloom period, high grow rate, etc.). Plant-pollinator networks provide valuable services to whole ecosystems and the introduction of an alien species may have different effects on the native network (competitive facilitation, native species extinction, etc.). While scientists acknowledge the significance of network connectivity in driving ecosystem services, the inclusion of temporary networks in ecological models is still in its infancy. We propose to use existing data on seasonality to develop a simulation platform that show inference between temporality of networks and invasions traits. Our focus is only to pick up some simple model to show, that theoretically temporal aspect play a role (different extinction patterns) to encourage ecologist to get involved in temporal networks. Moreover, the derived simulations could be further extended and adjust to other ecological questions.
