Cím:A mechanistic approach to understanding range shifts in a changing world : What makes a pioneer? / J. C. Wingfield, J. S. Krause, J. H. Perez, H. E. Chmura, Z. Németh, K. R. Word, R. M. Calisi, S. L. Meddle
Megjegyzések:A species' range can be thought of as a manifestation of the ecological niche in space. Within a niche, evo-lution has resulted in traits that maximize fitness. Across millennia, natural oscillations in temperaturehave caused shifts in the geographic location of appropriate habitat and with corresponding changesin species' ranges. Contemporary climate change and human disturbance may lead to rapid range expan-sion or contractions with largely unknown consequences. Birds provide an excellent case study of thisphenomenon with some taxa expanding range and others contracting even to the point of extinction.What leads some populations to expand while others contract? Are there physiological and behavioralattributes of ♭♭pioneers" at the forefront of a range shift/expansion?The concept of allostasis provides a framework with which to begin to evaluate when a species will beable to successfully expand into new habitat. This tool allows the integration of normal energeticdemands (e.g. wear and tear of daily and seasonal routines) with novel challenges posed by unfamiliarand human altered environments. Allostasis is particularly attractive because it allows assessment ofhow individual phenotypes may respond differentially to changing environments. Here, we use allostasisto evaluate what characteristics of individuals and their environment permit successful range expansion.Understanding variation in the regulatory mechanisms that influence response to a novel environmentwill be fundamental for understanding the phenotypes of pioneers.
