    Rapid evolution of a geographic cline in size in an introduced fly (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-01-15
    Description: The introduction and rapid spread of Drosophila subobscura in the New World two decades ago provide an opportunity to determine the predictability and rate of evolution of a geographic cline. In ancestral Old World populations, wing length increases clinally with latitude. In North American populations, no wing length cline was detected one decade after the introduction. After two decades, however, a cline has evolved and largely converged on the ancestral cline. The rate of morphological evolution on a continental scale is very fast, relative even to rates measured within local populations. Nevertheless, different wing sections dominate the New versus Old World clines. Thus, the evolution of geographic variation in wing length has been predictable, but the means by which the cline is achieved is contingent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huey, R B -- Gilchrist, G W -- Carlson, M L -- Berrigan, D -- Serra, L -- New York, N.Y. -- Science. 2000 Jan 14;287(5451):308-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Washington, Box 351800, Seattle, WA 98195-1800, USA. hueyrb@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10634786" target="_blank"〉PubMed〈/a〉

    Allometric engineering: a causal analysis of natural selection on offspring size (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-12-18
    Description: Techniques of offspring size manipulation, "allometric engineering," were used in combination with studies of natural selection to elucidate the causal relation between egg size and offspring survival of lizards. The results experimentally validate premises underlying theories of optimal egg size: fecundity selection favoring the production of large clutches of small eggs was balanced by survival selection favoring large offspring. However, large hatchlings did not always have the highest survival, contrary to most theoretical expectations. Optimizing selection on offspring size per se was the most common pattern. Moreover, matches between average and optimal egg size were qualitative, not quantitative, perhaps reflecting known functional constraints on the production of large eggs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinervo, B -- Zamudio, K -- Doughty, P -- Huey, R B -- New York, N.Y. -- Science. 1992 Dec 18;258(5090):1927-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17836187" target="_blank"〉PubMed〈/a〉

    Allometric engineering: an experimental test of the causes of interpopulational differences in performance (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-06-01
    Description: Hatchling lizards (Sceloporus occidentalis) from a southern population are large and have high locomotor performance (speed and stamina) relative to hatchlings from northern populations. In order to determine whether differences in performance are an allometric consequence of interpopulation differences in size, yolk was removed from southern eggs, thereby producing miniaturized hatchlings equivalent in size to northern hatchlings. Miniaturized southern hatchlings no longer had higher speed than northern hatchlings, but maintained higher stamina. Interpopulation differences in speed but not in stamina are thus an allometric consequence of differences in egg size. Size manipulation adds an experimental dimension to aliometric analyses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinervo, B -- Huey, R B -- New York, N.Y. -- Science. 1990 Jun 1;248(4959):1106-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17733374" target="_blank"〉PubMed〈/a〉

    Hypoxia, global warming, and terrestrial late Permian extinctions (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-04-16
    Description: A catastrophic extinction occurred at the end of the Permian Period. However, baseline extinction rates appear to have been elevated even before the final catastrophe, suggesting sustained environmental degradation. For terrestrial vertebrates during the Late Permian, the combination of a drop in atmospheric oxygen plus climate warming would have induced hypoxic stress and consequently compressed altitudinal ranges to near sea level. Our simulations suggest that the magnitude of altitudinal compression would have forced extinctions by reducing habitat diversity, fragmenting and isolating populations, and inducing a species-area effect. It also might have delayed ecosystem recovery after the mass extinction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huey, Raymond B -- Ward, Peter D -- New York, N.Y. -- Science. 2005 Apr 15;308(5720):398-401.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Washington, Box 351800, Seattle, WA 98195, USA. hueyrb@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15831755" target="_blank"〉PubMed〈/a〉

    Global metabolic impacts of recent climate warming (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-12
    Description: Documented shifts in geographical ranges, seasonal phenology, community interactions, genetics and extinctions have been attributed to recent global warming. Many such biotic shifts have been detected at mid- to high latitudes in the Northern Hemisphere-a latitudinal pattern that is expected because warming is fastest in these regions. In contrast, shifts in tropical regions are expected to be less marked because warming is less pronounced there. However, biotic impacts of warming are mediated through physiology, and metabolic rate, which is a fundamental measure of physiological activity and ecological impact, increases exponentially rather than linearly with temperature in ectotherms. Therefore, tropical ectotherms (with warm baseline temperatures) should experience larger absolute shifts in metabolic rate than the magnitude of tropical temperature change itself would suggest, but the impact of climate warming on metabolic rate has never been quantified on a global scale. Here we show that estimated changes in terrestrial metabolic rates in the tropics are large, are equivalent in magnitude to those in the north temperate-zone regions, and are in fact far greater than those in the Arctic, even though tropical temperature change has been relatively small. Because of temperature's nonlinear effects on metabolism, tropical organisms, which constitute much of Earth's biodiversity, should be profoundly affected by recent and projected climate warming.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dillon, Michael E -- Wang, George -- Huey, Raymond B -- England -- Nature. 2010 Oct 7;467(7316):704-6. doi: 10.1038/nature09407.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology and Physiology, University of Wyoming, Laramie, Wyoming 82071, USA.

    Global genetic change tracks global climate warming in Drosophila subobscura (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-02
    Description: Comparisons of recent with historical samples of chromosome inversion frequencies provide opportunities to determine whether genetic change is tracking climate change in natural populations. We determined the magnitude and direction of shifts over time (24 years between samples on average) in chromosome inversion frequencies and in ambient temperature for populations of the fly Drosophila subobscura on three continents. In 22 of 26 populations, climates warmed over the intervals, and genotypes characteristic of low latitudes (warm climates) increased in frequency in 21 of those 22 populations. Thus, genetic change in this fly is tracking climate warming and is doing so globally.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Balanya, Joan -- Oller, Josep M -- Huey, Raymond B -- Gilchrist, George W -- Serra, Luis -- New York, N.Y. -- Science. 2006 Sep 22;313(5794):1773-5.

    Ecophysiology. Climate change tightens a metabolic constraint on marine habitats (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-06-06
    Description: Warming of the oceans and consequent loss of dissolved oxygen (O2) will alter marine ecosystems, but a mechanistic framework to predict the impact of multiple stressors on viable habitat is lacking. Here, we integrate physiological, climatic, and biogeographic data to calibrate and then map a key metabolic index-the ratio of O2 supply to resting metabolic O2 demand-across geographic ranges of several marine ectotherms. These species differ in thermal and hypoxic tolerances, but their contemporary distributions are all bounded at the equatorward edge by a minimum metabolic index of ~2 to 5, indicative of a critical energetic requirement for organismal activity. The combined effects of warming and O2 loss this century are projected to reduce the upper ocean's metabolic index by ~20% globally and by ~50% in northern high-latitude regions, forcing poleward and vertical contraction of metabolically viable habitats and species ranges.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deutsch, Curtis -- Ferrel, Aaron -- Seibel, Brad -- Portner, Hans-Otto -- Huey, Raymond B -- New York, N.Y. -- Science. 2015 Jun 5;348(6239):1132-5. doi: 10.1126/science.aaa1605.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Oceanography, University of Washington, Seattle, WA 98195, USA. cdeutsch@uw.edu. ; Department of Atmospheric and Oceanic Sciences, University of California, Los Angeles, CA 90095, USA. ; Biological Sciences Department, University of Rhode Island, Kingston, RI 02881, USA. ; Alfred Wegener Institute, D-27570 Bremerhaven, Germany. ; Department of Biology, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26045435" target="_blank"〉PubMed〈/a〉
