Abstract Biodiversity generally increases productivity in ecosystems; however, this is mediated by the specific functional traits that come with biodiversity loss or gain and how these interact environmental conditions. Most studies evaluate effects of species richness alone, despite our increasing understanding intraspecific diversity can have equally strong impacts. Here, we manipulate both (i.e., number distinct strains) marine diatom communities to explicitly test relative importance strain for biomass trait six temperature/nutrient environments. We show significant on growth rates, but more importantly, they each other, indicating cross‐species depend within‐species vice versa. This intertwined relationship thus calls integrative approaches quantifying components context ecosystem functioning.

Abstract Environmental change profoundly alters biodiversity and, by extension, species contributions to ecosystem functioning. While it is well‐established that these impacts can be geographically and temporally nuanced, most assessments of ecosystems assume traits are spatially fixed, those do acknowledge intraspecific variability have failed fully determine its relevance Here, using three distinct populations sediment‐dwelling invertebrates, we combine a laboratory experiment with Bayesian hierarchical modelling empirically quantify the prevalence trait in relation geographic locality seasonal conditions. Furthermore, assessed role mediating sediment particle mixing, nutrient generation benthic oxygen uptake. We found body size reworking modified macrofaunal total uptake generation. These associations, however, were not consistent across all measured functions. Our findings highlight asymmetries both absolute magnitude and/or direction responses changing conditions, indicating relative functional make or transient may, therefore, diverge from expectations based on contemporary group typologies. critical knowledge gap our understanding key sources affecting functionally important aspects behaviour physiology call for development dynamic ecological assessment management approaches account individual as well environments.
