A species-level multi-trophic metaweb for Switzerland

Merin Reji Chacko, Camille Albouy, Florian Altermatt, Joan Casanelles‐Abella et autres

Understanding how species interact within ecological networks is essential for predicting the consequences of environmental change, from trophic cascades to broader changes in species distributions and ecosystem functioning across large spatial scales. To facilitate such explorations, we constructed trophiCH: a country-level trophic …

Species loss in key habitats accelerates regional food web disruption

Merin Reji Chacko, Camille Albouy, Florian Altermatt, Victor Boussange et autres

Understanding the robustness of ecological networks against sustained species losses is paramount to devising effective biodiversity conservation strategies. To explore the impacts of species losses on network robustness (the capacity of food webs to withstand primary extinctions), we used a trophic metaweb …

Environment‐driven plasticity in foraging behaviour: From individual‐level processes to community‐level consequences

Hsi‐Cheng Ho, Chi‐Yun Kuo

Abstract Plasticity describes the ability of a genotype to adaptively produce different phenotypes in response to environmental cues. Even though the concept of phenotypic plasticity was originally conceived for morphological characters, environmentally cued modification of behaviour has been recognized as an immediate …

Mechanistic insights on riverine meta-ecosystems: Network shape drives spatial biodiversity and trophic structures

Luca Carraro, Hsi‐Cheng Ho

Rivers exhibit hierarchical spatial structures of habitat and physical attributes, providing directed pathways for biological population and community dynamics and thus shaping the meta-ecosystems therein. While the River Continuum Concept has generalized the spatial patterns of abiotic and biotic components along rivers, …

Predicted community consequences of spatially explicit global change‐induced processes on plant–insect networks

Hsi‐Cheng Ho, Florian Altermatt

Abstract Plant–insect trophic systems should be particularly sensitive to processes altering species spatial co‐occurrences, as impacts on one level can cascade effectively through the strong trophic reliance to the other level. Here, we predicted the biogeography of Lepidoptera–plant communities under global‐change scenarios, …

trophiCH - a national species-level trophic metaweb of 23k species for Switzerland

Merin Reji Chacko, Camille Albouy, Florian Altermatt, Joan Casanelles‐Abella et autres

Environmental pressures on species can cascade within food webs and even extend beyond individual ecosystems to interconnected systems at large spatial scales. To facilitate the exploration of these dynamics, we construct a data-based national trophic meta-food web (henceforth metaweb), that includes well-documented …

The environment to the rescue: can physics help predict predator–prey interactions?

Mehdi Cherif, Ulrich Brose, Myriam R. Hirt, Remo Ryser et autres

Understanding the factors that determine the occurrence and strength of ecological interactions under specific abiotic and biotic conditions is fundamental since many aspects of ecological community stability and ecosystem functioning depend on patterns of interactions among species. Current approaches to mapping food …

Associating the structure of Lepidoptera‐plant interaction networks across clades and life stages to environmental gradients

Hsi‐Cheng Ho, Florian Altermatt

Abstract Aim The spatial‐structural patterns of plant‐insect interaction networks, particularly their associations with landscape‐scale environmental factors, remain poorly understood. We apply data‐driven network constructions that integrate biogeographic and trophic interaction knowledge to uncover how Lepidoptera‐plant networks vary across environmental gradients in a …

Coupled biological and hydrological processes shape spatial food-web structures in riverine metacommunities

Hsi‐Cheng Ho, Florian Altermatt, Luca Carraro

Introduction Understanding how species are distributed in space and how they interact with each other is central for scientific and conservation purposes. Species' distributions and interactions result from a complex interplay of local trophic dynamics, dispersal processes, resource availability, and abiotic factors …
