Abstract Globally, freshwater ecosystems are warming at unprecedented rates and northern temperate lakes simultaneously experiencing increased runoff of humic substances (brownification), with little known consequences for future conservation biodiversity ecosystem functioning. We employed an outdoor mesocosm experiment during spring summer to investigate the combined effects gradually increasing brownification perturbations on phytoplankton community structure (biodiversity composition) functioning (biomass). While we did not observe overall significant treatment total biomasses, show that predicted increases in can reduce considerably, occasionally up 90% Shannon diversity estimates. Our results demonstrate loss is driven by dominance mixotrophic algae ( Dinobryon Cryptomonas ), whereas several other taxa may be temporarily displaced from community, including Cyclotella , Desmodesmus Monoraphidium Tetraedron Nitzschia Golenkinia . The observed coincided increase bacterial production providing resources potential mixotrophs along gradient brownification. This coupling between was likely a major cause behind competitive displacement obligate phototrophs supports evidence importance consumer–prey dynamics shaping environmental impacts communities. conclude profound indirectly affecting interactions among taxa. Importantly, our abrupt biodiversity; instead reduction richness levelled off after exceeding threshold These exemplify complex nonlinear responses provide further insights predicting patterns freshwaters.

Climate warming can destabilize interactions between competitors as smaller organisms gain advantages in warmer environments. Whether and how warming-induced effects on competitive are modified by predation remains unknown. We hypothesized that will offset the advantage of prey species environments because their greater vulnerability to predation. To test this, we assembled a litter arthropod community with two Collembola ( Folsomia candida Proisotoma minuta ) different body sizes across temperature gradient (three thermal environments) presence absence predatory mites. Predatory mites reduced coexistence increasing temperatures. Contradicting our hypothesis, larger always outperformed predators. Larger probably benefited they expressed trait (body length) plasticity warming. Warming thus magnify reduce probability coexistence.
