    • The importance of plant genotype and contemporary evolution for terrestrial ecosystem processes 

      Fitzpatrick, C. R.; Agrawal, Anurag A.; Basiliko, N.; Hastings, Amy P.; Isaac, M. E.; Preston, M.; Johnson, Mark T. (Ecological Society of America, 2015-10-01)
      Plant genetic variation and evolutionary dynamics are predicted to impact ecosystem processes but these effects are poorly understood. Here we test the hypothesis that plant genotype and contemporary evolution influence ...

    • The interaction of photoperiod and temperature in diapause timing: a copepod example 

      Hairston, Nelson G., Jr.; Kearns, C. M. (University of Chicago Press, 1995-08)
      In many organisms, photoperiod and temperature are thought to be the most significant token cues for seasonally timed life history events, including diapause in arthropods. A common pattern in many species of terrestrial ...

    • The raison d'etre of chemical ecology 

      Raguso, Robert A.; Agrawal, Anurag A.; Douglas, Angela E.; Jander, Georg; Kessler, Andre; Poveda, Katja; Thaler, Jennifer S. (Ecological Society of America, 2015-03-01)
      Chemical ecology is a mechanistic approach to understanding the causes and consequences of species interactions, distribution, abundance, and diversity. The promise of chemical ecology stems from its potential to provide ...

    • The role of technology and policy in mitigating regional nitrogen pollution 

      Gu, Baojing; Zhu, Yimei; Chang, Jie; Peng, Chanhui; Liu, Dong; Min, Yong; Luo, Weidong; Howarth, R. W.; Ge, Y. (Institute of Physics Publishing, 2011-03-01)
      Human activity greatly influences nitrogen (N) pollution in urbanized and adjacent areas. We comprehensively studied the N cycling in an urban-rural complex system, the Greater Hangzhou Area (GHA) in southeastern China. ...

    • The timing of copepod diapause as an evolutionarily stable strategy 

      Hairston, Nelson G., Jr.; Munns, Wayne R. (University of Chicago, 1984-06)
      Diaptomus sanguineus, a small freshwater copepod, avoids periods of intense fish predation by producing diapausing eggs. We developed a computer simulation of the copepod's life history and used it to compete populations ...

    • Toward a better understanding and quantification of methane emissions from shale gas development 

      Caulton, D.R.; Shepson, P. B.; Santoro, R.L.; Sparks, J.P.; Howarth, R. W.; Ingraffea, A.; Camaliza, M.O.; Sweeney, C.; Karion, A.; Davis, K.J.; Stirm, B.H.; Montzka, S.A.; Miller, B. (National Academy of Sciences, 2014-04-29)
      The identification and quantification of methane emissions from natural gas production has become increasingly important owing to the increase in the natural gas component of the energy sector. An instrumented aircraft ...

    • Toward a Predictive Framework for Convergent Evolution: Integrating Natural History, Genetic Mechanisms, and Consequences for the Diversity of Life 

      Agrawal, Anurag A. (University of Chicago Press, 2017-08)
      A charm of biology as a scientific discipline is the diversity of life. Although this diversity can make laws of biology challenging to discover, several repeated patterns and general principles govern evolutionary ...

    • Transgenerational Consequences of Plant Responses to Herbivory: An Adaptive Maternal Effect 

      Agrawal, Anurag A. (University of Chicago Press, 2000-12-21)
      Herbivory has many effects on plants, ranging from shifts in primary processes such as photosynthesis, growth, and phenology to effects on defense against subsequent herbivores and other species interactions. In this study, ...

    • Vascular Plant Species of the Cayuga Region of New York State 

      Wesley, F. Robert; Gardescu, Sana; Marks, P. L. (2008-01-01)
      This dataset lists the vascular plants found in a region of central New York State extending from 42 N to 43 N, and 76 W to 77 W (the USGS "Cayuga Quadrangle"), plus a small area north of 43 degrees in the "Cayuga Lake ...

    • Water resources, agriculture and the environment. 

      Pimentel, David; Berger, Bonnie; David, Filiberto; Newton, Michelle; Wolfe, Benjamin; Karabinakis, Elizabeth; Clark, Steven; Poon, Elaine; Abbett, Elizabeth; Nandagopal, Sudha (2004-07)
      In this article, water utilization by individuals and especially agricultural systems is analyzed. Interrelationships exist among population growth, water use and distribution, the status of biodiversity, the natural ...
