Introducing the concepts of range-pinning and Allee effects to explain reduced temperature sensitivity of global treeline dynamics

Popis výsledku v původním jazyce

Treeline studies are often motivated by the general assumption that cold distribution limits of the lifeform tree represent a universal biogeographic margin that is particularly sensitive to recent global warming. But the existing body of scientific literature is less consistent and raises more questions than it provides answers. Not only is the rate of treeline advancement in response to rising temperatures poorly understood, but interactions between biotic and abiotic drivers of treeline dynamics, as well as ecological mechanisms behind surprisingly stable treeline positions also remain unclear. Here, we argue that natural treeline ecotones in undisturbed alpine and arctic settings are less sensitive to the ongoing anthropogenic warming trend than commonly assumed. To foster our hypothesis, we first recognize that the conceptual distinction between actual (realized) and potential (theoretical) treeline positions requires an additional differentiation of actual treelines into those that are undisturbed natural versus those that are created artificially (i). We also suggest that the growth sensitivity of individual treeline trees to climate should not be confused with the climate dependency of recruitment rates and age structures of entire treeline populations (ii). We then introduce the concept of range-pinning, an emergent property resulting from the interactions of dispersal with the Allee effect (ie a positive relationship between population density and individual fitness), which also may constrain species ranges from expanding at the edge of suitable habitats.
