CLIMATE CHANGE AND ANTHROPOGENIC FOOD MANIPULATION INTERACT IN SHIFTING THE DISTRIBUTION OF A LARGE HERBIVORE AT ITS ALTITUDINAL RANGE LIMIT

Climate change and anthropogenic food manipulation interact in shifting the distribution of a large herbivore at its altitudinal range limit

Abstract Ungulates in alpine ecosystems are constrained by winter harshness through resource limitation and direct mortality from weather extremes.However, little empirical evidence has definitively established how current climate change and other anthropogenic modifications of resource availability affect ungulate winter distribution, especially a

A numerical approach for detecting switch-like bistability in mass action chemical reaction networks with conservation laws

Abstract Background Theoretical analysis of signaling pathways can provide a substantial amount of insight into their function.One particular area of research considers signaling pathways capable of assuming two or more stable states given the same amount of signaling ligand.This phenomenon of bistability can give rise to switch-like behavior, a me
