Journal ArticleDOI
Universal temperature and body-mass scaling of feeding rates.
Björn C. Rall,Ulrich Brose,Martin Hartvig,Martin Hartvig,Gregor Kalinkat,Gregor Kalinkat,Florian Schwarzmüller,Olivera Vucic-Pestic,Owen L. Petchey +8 more
TL;DR: These body-mass- and temperature-scaling models remain useful as a mechanistic basis for predicting the consequences of warming for interaction strengths, population dynamics and network stability across communities differing in their size structure.
Journal ArticleDOI
Temperature, predator-prey interaction strength and population stability
TL;DR: The results suggest that warming has complex and potentially profound effects on predator–prey interactions and food-web stability, and suggests an increase in perturbation stability of populations.
Journal ArticleDOI
Warming up the system: higher predator feeding rates but lower energetic efficiencies
TL;DR: Environmental warming generally increases the direct short-term per capita interaction strengths between predators and their prey as described by functional-response models, which implies that warming of natural ecosystems may dampen predator–prey oscillations thus stabilizing their dynamics.
Journal ArticleDOI
Allometric functional response model: body masses constrain interaction strengths.
TL;DR: The results imply that predators of intermediate size impose stronger per capita top-down interaction strengths on a prey than smaller or larger predators, and the stability of population and food-web dynamics should increase with increasing body-mass ratios in consequence of increases in the scaling exponents.
Journal ArticleDOI
Foraging theory predicts predator-prey energy fluxes
Ulrich Brose,Roswitha B. Ehnes,Björn C. Rall,Olivera Vucic-Pestic,Eric L. Berlow,Stefan Scheu +5 more
TL;DR: Surprisingly, contrary to predictions of metabolic models, this suggests that for any prey species, the per link and total energy fluxes to its largest predators are smaller than those to predators of intermediate body size.
