Metabolomics data is rich and often large, containing far more variables than samples while many features remain unannotated. Therefore, the analysis of metabolomics data is not trivial and calls for approaches complementary to (multivariate) statisticial analyses not only to overcome the metabolite annotation bottleneck, but more importantly, to facilitate the rapid exploration of the...

Agricultural fields are a habitat type which can exhibit a high amount of biodiversity depending on the management intensity.

International commitments promote large-scale forest restoration as a nature-based solution to mitigate climate change through carbon (C) sequestration.

Survival of wild bees is threatened by multiple factors such as agricultural intensification, scarcity of food resources and diseases. Many pathogens are shared between managed and wild bee species, with flowers as the most likely route of interspecific transmission. An increased density of managed pollinators in the landscape may therefore aggravate pathogen spillover among communities of...

Symbionts are integral to arthropod biology, profoundly shaping their hosts' phenotypic traits and playing a pivotal role in speciation. While these associations can be costly for insect hosts, they are typically stable and maternally transmitted with high fidelity. However, the absence of co-cladogenesis suggests that many symbiont-host relationships are transient over evolutionary...

Trait-based ecology assumes that functional traits help to understand how organisms influence ecosystem processes.
