Synthesizing the relationships between food web structure and robustness

Species are being lost from ecosystems, and for more than 20 years, ecologists have sought to understand the extent to which these species losses trigger secondary extinctions—i.e., the additional loss of species following lost resources or key interactions—measured as robustness. In particular, ecologists aim to identify generalizable rules that explain which types of food webs are more or less robust to secondary extinctions. Food web structure, or the patterns formed by species and their interactions, has been extensively studied as a potential factor that influences robustness. However, there has not yet been a review of our understanding of the relationships between food web structure and robustness. We systematically reviewed 28 studies to identify the relationships between food web structures and robustness, and how the conclusions depend on methodological differences. More than 20 food web structures were reported to determine robustness, but the shape and direction of these rel..., We conducted a systematic literature review following the Reporting standards for Systematic Evidence Synthesis (ROSES) protocol from Haddaway et al. (2017), we described our process in full in Supporting Fig.1. This review involved two stages: 1. abstract screening, and 2. full paper review. We queried the Web of Science Core Collection on April 22, 2021, using the search string: TS= (((“food web” OR food-web) AND (robustness OR persistence OR fragility OR “cascad* extinction*” OR “second* extinction*”))), which yielded 1,107 papers. Our choice of search terms is likely biased towards English language studies, which we acknowledge as an important caveat. Our search terms intentionally do not include network structure or properties given the diverse vocabulary used to describe these ideas (e.g., complexity, structure, properties, attributes). Instead, we queried for all papers that considered the interactions we were interested in (i.e., trophic interactions in food webs) and the simula..., , # Data from: Synthesizing the relationships between food web structure and robustness

This dataset includes data from each step of our literature review that aimed to identify whether there are relationships between food web structure and robustness. There are 5 files included.

## Description of the data and file structure

There are 5 files included in this repository:

Supplementary File 1: This file includes all of the papers and references considered at each stage of our review including 1. the 1,107 papers that we queried from the Web of Science Database, the first round filter of papers based on whether the abstracts met our inclusion requirements: 1. the authors studied food webs, 2.  authors simulated species losses (either computationally or by experimental removal of species), and 3. authors studied at least one food web property or structure in relation to robustness, the second round filter...

生态系统中正经历物种丧失，二十余年来，生态学家一直致力于探究物种丧失在多大程度上会引发次生灭绝（secondary extinctions）——即因资源丧失或关键交互作用消失而导致的额外物种消亡，这一过程以稳健性（robustness）进行量化衡量。具体而言，生态学家旨在发掘可推广的规律，以阐释哪些类型的食物网（food web）对次生灭绝的抵抗能力更强或更弱。食物网结构（food web structure），即由物种及其交互作用所构成的模式，作为影响稳健性的潜在因素已得到广泛研究，但目前尚无综述对学界关于食物网结构与稳健性之间关联的认知进行梳理。我们系统性综述了28项研究，以明确食物网结构与稳健性之间的关联，以及研究结论如何因方法学差异而有所不同。已有研究报道了20余种可决定稳健性的食物网结构，但这些关联的形式与方向……
我们遵循Haddaway等人（2017）提出的《系统性证据综合报告标准（Reporting standards for Systematic Evidence Synthesis, ROSES）》流程开展了系统性文献综述，完整的研究流程已在补充图1中予以说明。本次综述分为两个阶段：1. 摘要筛选；2. 全文审阅。我们于2021年4月22日在Web of Science核心合集（Web of Science Core Collection）中进行检索，检索式为：TS= ((("food web" OR food-web) AND (robustness OR persistence OR fragility OR "cascad* extinction*" OR "second* extinction*"))), 共检索得到1107篇文献。我们承认，检索词的选择可能会偏向英文文献，这是本研究的一项重要局限。考虑到用于描述此类概念的词汇存在多样性（如复杂性、结构、属性、特征等），我们的检索词刻意未包含网络结构或网络属性。取而代之的是，我们检索了所有涉及我们关注的交互作用（即食物网中的营养级交互作用（trophic interactions））以及模拟……的文献。
