英文摘要: Biological effects of climate change are expected to vary geographically, with a strong signature of latitude. For ectothermic animals, there is systematic latitudinal variation in the relationship between climate and thermal performance curves, which describe the relationship between temperature and an organism's fitness. Here, we ask whether these documented latitudinal patterns can be generalized to predict arthropod responses to warming across mid- and high temperate latitudes, for taxa whose thermal physiology has not been measured. To address this question, we used a novel natural experiment consisting of a series of urban warming gradients at different latitudes. Specifically, we sampled arthropods from a single common street tree species across temperature gradients in four US cities, located from 35.8 to 42.4° latitude. We captured 6746 arthropods in 34 families from 111 sites that varied in summer average temperature by 1.7–3.4 °C within each city. Arthropod responses to warming within each city were characterized as Poisson regression coefficients describing change in abundance per °C for each family. Family responses in the two midlatitude cities were heterogeneous, including significantly negative and positive effects, while those in high-latitude cities varied no more than expected by chance within each city. We expected high-latitude taxa to increase in abundance with warming, and they did so in one of the two high-latitude cities; in the other, Queens (New York City), most taxa declined with warming, perhaps due to habitat loss that was correlated with warming in this city. With the exception of Queens, patterns of family responses to warming were consistent with predictions based on known latitudinal patterns in arthropod physiology relative to regional climate. Heterogeneous responses in midlatitudes may be ecologically disruptive if interacting taxa respond oppositely to warming. © 2016 John Wiley & Sons Ltd

Permission to sample arthropods in street trees was granted by the Raleigh Parks, Recreation, and Cultural Resources Department, the City of Baltimore Department of Recreation and Parks, the New York State Department of Environmental Conservation (scientific collecting license #1820), the New York City Department of Parks and Recreation, and the Boston Parks and Recreation Department. Sally Thigpen (Raleigh), Erik Dihle (Baltimore), Jaqueline Lu and Nancy Falxa-Sonti (Queens), and Kyle Greaves, Greg Mosman, and Carl Spector (Boston) facilitated permissions and provided helpful local information and street tree inventories. This study was supported by an NSF RAPID (1318655) to S.D.F. and R.R.D. and by an Agriculture and Food Research Initiative Competitive Grant (2013-02476) from the USDA National Institute of Food and Agriculture to S.D.F. and E.Y.
