The temperature dependence of predation rates is a key issue for understanding and predicting the responses ecosystems to climate change. Using simple mechanistic model, we demonstrate that differences in relative performances predator prey can cause strong threshold effects attack rates. Empirical data on rate northern pike ( Esox lucius ) feeding brown trout Salmo trutta confirm this result. Attack fell sharply below +11°C, which corresponded shift performance with respect maximum escape...
Summary Climate change is expected to not only raise water temperatures, but also cause brownification of aquatic ecosystems via increased inputs terrestrial dissolved organic matter. While efforts have been made understand how temperature and separately influence food webs, their interactive effects less investigated. Further, although climate on likely will propagate consumers changes in insect emergence, this has rarely studied. We investigated the effect a large‐scale outdoor pond...
Abstract In shallow lakes, pelagic and benthic producers engage in spatially asymmetrical resource competition. Pelagic intercept the flux of light to habitat sediment‐derived nutrients habitat. boreal subarctic regions, climate change is affecting this interaction both directly through warming indirectly increased loading with colored dissolved organic matter ( cDOM ) from catchment (“brownification”). We use a dynamical ecosystem model explore consequences these changing environmental...
Productivity and trophic structure of aquatic ecosystems result from a complex interplay bottom-up top-down forces that operate across benthic pelagic food web compartments. Projected global changes urge the question how this will be affected by browning (increasing input terrestrial dissolved organic matter), nutrient enrichment warming. We explored with process-based model shallow lake consisting components (abiotic resources, primary producers, grazers, carnivores), compared expectations...
In northern climates, winter is a bottleneck for many organisms. Low light and resource availability constrains individual foraging rates, potentially leading to starvation increased mortality. Increasing input of humic substances aquatic ecosystems causes brownification water hence further decrease availability, which may lead decreased rates mortality during winter. To test this hypothesis, we measured the effects experimentally on consumption survival young-of-the-year three-spined...
