Abstract

This study provides a pioneering analysis of the structural and topological characteristics of one of nature's simplest food webs, using the Montaña Clara islet (Canary Islands) as a case study. Applying a multilayer network approach, which assesses multiple interaction types, we examined plant–animal and plant-fungi interactions during two seasons (humid and dry), comparing this oceanic island food web to one from Na Redona, a small continental island in the Balearic Islands. Data were collected through field observations, flower visitation records, fecal analysis, and DNA metabarcoding of root-associated fungi. The study identified 63 animal species and 367 fungal amplicon sequence variants interacting with 13 plant species, five of which (38%) were structurally significant, as indicated by high multilayer versatility values (>0.5). The network structure was modular, with 23 modules primarily representing single ecological functions, and most species were involved in only one interaction type. Notably, 73% of species shifted roles between interaction layers. Results reveal that Montaña Clara's food web is simpler but more modular and versatile than that of the continental island, aligning with island biogeography theory. The study suggests that the unique biodiversity composition of oceanic islands, particularly islets, influences their ecological network structures.

解开小岛屿多层网络:潜在的生态和进化模式
本研究以Montaña Clara岛(加那利群岛)为例,对自然界最简单的食物网之一的结构和拓扑特征进行了开创性的分析。应用多层网络方法,评估多种相互作用类型,我们研究了植物-动物和植物-真菌在两个季节(潮湿和干燥)的相互作用,并将这个海洋岛屿食物网与巴利阿里群岛的一个小大陆岛屿Na Redona的食物网进行比较。通过野外观察、访花记录、粪便分析和根相关真菌的DNA元条形码收集数据。研究发现63种动物和367种真菌扩增子序列变异与13种植物相互作用,其中5种(38%)结构显著,具有较高的多层通用性值(>0.5)。网络结构是模块化的,有23个模块主要代表单一的生态功能,大多数物种只参与一种相互作用类型。值得注意的是,73%的物种在相互作用层之间转换角色。结果表明Montaña Clara的食物网比大陆岛的食物网更简单,但更模块化和多样化,与岛屿生物地理学理论一致。研究表明,海洋岛屿特别是小岛独特的生物多样性构成影响了其生态网络结构。

期刊介绍: Ecology publishes articles that report on the basic elements of ecological research. Emphasis is placed on concise, clear articles documenting important ecological phenomena. The journal publishes a broad array of research that includes a rapidly expanding envelope of subject matter, techniques, approaches, and concepts: paleoecology through present-day phenomena; evolutionary, population, physiological, community, and ecosystem ecology, as well as biogeochemistry; inclusive of descriptive, comparative, experimental, mathematical, statistical, and interdisciplinary approaches.
