Do growing degree days predict phenology across butterfly species?
Global climate change is causing shifts in phenology across multiple species. We use a geographically and temporally extensive data set of butterfly abundance across the state of Ohio to ask whether phenological change can be predicted from climatological data. Our focus is on growing degree days (GDD), a commonly used measure of thermal accumulation, as the mechanistic link between climate cha...
متن کاملCan Growing Degree Days and Photoperiod Predict Spring Wheat Phenology?
Wheat (Triticum aestivum) production in the rainfed area of Pothwar Pakistan is extremely vulnerable to high temperature. The expected increase in temperature due to global warming should result in shorter crop life cycles, and thus lower biomass and grain yield. Two major factors control wheat phenological development: temperature and photoperiod. To evaluate wheat development in response to t...
متن کاملGrowing degree-days: one equation, two interpretations
Heat units, expressed in growing degree-days (GDD), are frequently used to describe the timing of biological processes. The basic equation used is GDD = [(T,,, + TM,,)/2] T,,,,, where T, and T,,, are daily maximum and minimum air temperature, respectively, and T,, is the base temperature. Two methods of interpreting this equation for calculating GDD are: (1) if the daily mean temperature is les...
متن کاملCoping with shorter days: do phenology shifts constrain aphid fitness?
Climate change can alter the phenology of organisms. It may thus lead seasonal organisms to face different day lengths than in the past, and the fitness consequences of these changes are as yet unclear. To study such effects, we used the pea aphid Acyrthosiphon pisum as a model organism, as it has obligately asexual clones which can be used to study day length effects without eliciting a season...
متن کاملPhenology, reproductive biology and growing degree days of the grapevine 'Isabel' (Vitis labrusca, Vitaceae) cultivated in northeastern Brazil.
Phenology and reproductive biology of cultivated species are important for the comprehension of the requirements for fruit and seed production and the management of pollinators. This study aimed to characterise the phenology, reproductive biology and growing degree days of the grapevine 'Isabel' (Vitis labrusca) in northeastern Brazil during January 2011 (P1), Augst 2011 (P2), April 2012 (P3) a...
