Climate change studies have long focused on effects of increasing temperatures, often without considering other simultaneously occurring environmental changes, such as browning waters. Resolving how the combination warming and aquatic ecosystems affects fish biomass production is essential for future ecosystem functioning, fisheries, food security. In this study, we analyzed individual- population-level data from 52 temperate boreal lakes in Northern Europe, covering large gradients water...
Abstract A challenge facing ecologists trying to predict responses climate change is the few recent analogous conditions use for comparison. For example, negative relationships between ectotherm body size and temperature are common both across natural thermal gradients in small‐scale experiments. However, it unknown if short‐term representative of long‐term responses. Moreover, understand population warming, we must recognize that individual may vary over ontogeny. To enable predictions how...
Abstract Body size is a key trait in ecology due to its influence on metabolism and many other life‐history traits that affect population community responses environmental variation as well ecosystem properties. The spectrum represents the relationship between abundance (or biomass) body size, independent of species identity. Size parameters, such slope or intercept, have been applied extensively indicators ecological status across multiple types. GLOSSAQUA dataset includes data from mainly...
Abstract Trophic transfer efficiency (TTE) is usually calculated as the ratio of production rates between two consecutive trophic levels. Although seemingly simple, TTE estimates from lakes are rare. In our review, we explore processes and structures that must be understood for a proper lake estimate. We briefly discuss measurements positions mention how ecological efficiencies, nutrients (N, P) other compounds (fatty acids) affect energy levels hence TTE. Furthermore, elucidate linked with...
Abstract Browning of waters, coupled to climate change and land use changes, can strongly affect aquatic ecosystems. Browning‐induced light limitation may have negative effects on consumers via shifts in resource composition availability by negatively affecting foraging relying vision. However, the extent which caused browning affects fish either these two pathways is largely unknown. Here we specifically test if growth responses a pelagic food web are best explained changes due limitation,...
Size-specific body growth responses to warming are common among animal taxa, but sex-specific poorly known. Here we ask if sex-dependent, and such vary with size age. This was tested data of back-calculated individual trajectories, in European perch ( Perca fluviatilis) from a long-term whole-ecosystem experiment (6.3 °C above the surrounding sea). Warming led both size- differences responses. had consistent positive effect on females, negative effects male at > 10 cm age 2 years. These...
Abstract Organisms are facing global climate change and other anthropogenic pressures, but most research on responses to such changes only considers effects of single drivers. Observational studies physiological experiments suggest temperature increases will lead faster growth small fish. Whether this effect warming holds in more natural food web settings with concurrent drivers, as darkening water color (“browning”) is, however, unknown. Here, we set up a pelagic mesocosm experiment large...
An organism's body size plays an important role in ecological interactions such as predator-prey relationships. As predators are typically larger than their prey, this often leads to a strong positive relationship between and trophic position aquatic ecosystems. The distribution of sizes community can thus be indicator the strengths interactions. aim study was gain more insight into fish wide range European lakes. We used quantile regression examine species' log-transformed maximum mass for...
Abstract Ongoing climate change is leading to browning of many lakes and coastal areas, which can impair fish body growth biomass production. However, whether how effects light limitation caused by on vary over early ontogeny unknown. In this study, we set up a mesocosm experiment test roach ( Rutilus rutilus ) responses depend size, if findings are robust densities. We also studied potential mechanism for size‐specific conducting an aquaria prey selectivity in changes with browning. found...
