Environmental factors can influence ecological networks, but these effects are poorly understood in the realm of phylogeny host-parasitoid interactions. Especially, we lack a comprehensive understanding ways that biotic factors, including plant species richness, overall community phylogenetic and functional composition consumers, abiotic such as microclimate, determining host–parasitoid network structure dynamics. To address this, leveraged five-year dataset trap-nesting bees wasps their parasitoids collected highly-controlled, large-scale subtropical tree biodiversity experiment. We tested for diversity, on diversity both host parasitoid communities interaction networks. show multiple components canopy cover impacted both, hosts parasitoids. Generally, associations between reflected non-randomly structured interactions trees Further, was influenced by cover. Our study indicates higher trophic levels corresponding networks determined especially via links species-rich ecosystems.
