      Doubek, Jonathan P.; Carey, Cayelan C.; Lavender, Michael; Winegardner, Amanda K.; Beaulieu, Marieke; Kelly, Patrick T.; Pollard, Amina I.; Straile, Dietmar; Stockwell, Jason D. (PLOS, 2019-01-09)
      Inherent differences between naturally-formed lakes and human-made reservoirs may play an important role in shaping zooplankton community structure. For example, because many reservoirs are created by impounding and managing ...
    • Can Humans Respond to a Long-term Shortage of Renewable Resources 

      Cairns, John (Virginia Tech, 2011)

      Cairns, John (Virginia Tech, 2005)
      The severity of the latest natural disasters and the increased probability of other major disruptions due to climate change mandate further examination of the consequences of such events on human society. Current unsustainable ...
    • Can the Cheap, Convenient, Readily Available Energy Party Continue 

      Cairns, John (Virginia Tech, 2006)
      Persuasive evidence indicates that oil supplies are peaking and therefore humans should expect for alternative fuels to play a major part in the future energy market.
    • Can we improve estimates of juvenile dispersal distance and survival? 

      Cooper, C. B.; Daniels, S. J.; Walters, J. R. (Ecological Society of America, 2008-12)
      Estimates of distributions of natal dispersal distances and juvenile recruitment rates in open populations are strongly influenced by the extent and shape of the areas sampled. Techniques to improve biased dispersal and ...
    • Cancer karyotypes: survival of the fittest 

      Nicholson, Joshua M.; Cimini, Daniela (Frontiers, 2013)
      Cancer cells are typically characterized by complex karyotypes including both structural and numerical changes, with aneuploidy being a ubiquitous feature. It is becoming increasingly evident that aneuploidy per se can ...
    • Candidate Gene Sequence Analyses toward Identifying Rsv3-Type Resistance to Soybean Mosaic Virus 

      Redekar, N. R.; Clevinger, E. M; Laskar, M. A.; Biyashev, R. M.; Ashfield, T.; Jensen, Roderick V.; Jeong, S. C.; Tolin, S. A.; Maroof, M. A. Saghai (Crop Science Society of America, 2016-05-13)
      Rsv3 is one of three genetic loci conferring strain-specific resistance to Soybean mosaic virus (SMV). The Rsv3 locus has been mapped to a 154-kb region on chromosome 14, containing a cluster of five nucleotide-binding ...
    • Carbon dioxide stimulates lake primary production 

      Hamdan, Mohammed; Byström, Pär; Hotchkiss, Erin R.; Al-Haidarey, Mohammed J.; Ask, Jenny; Karlsson, Jan (Springer Nature, 2018-07-18)
      Gross primary production (GPP) is a fundamental ecosystem process that sequesters carbon dioxide (CO2) and forms the resource base for higher trophic levels. Still, the relative contribution of different controls on GPP ...
    • Cast Changes on the Ecological Stage of Earth's Evolutionary Theater 

      Cairns, John (Virginia Tech, 2009)
      Change has been the Earth s most notable feature for the past 4 billion years. Earth has already passed two ecological tipping points with the acidification of the oceans and the melting glaciers and ice sheets, both caused ...
    • Cavity excavation and enlargement as mechanisms for indirect interactions in an avian community 

      Blanc, Lori A.; Walters, Jeffrey R. (Ecological Society of America, 2008-02)
      Direct and indirect species interactions within ecological communities may play a strong role in influencing or maintaining community structure. Complex community interactions pose a major challenge to predicting ecosystem ...
    • Cell Cycle Control by a Minimal Cdk Network 

      Gerard, C.; Tyson, John J.; Coudreuse, D.; Novak, B. (PLOS, 2015-02-01)
    • Cell Cycle Model System for Advancing Cancer Biomarker Research 

      Lazar, Iulia M.; Hoeschele, Ina; de Morais, Juliana; Tenga, Milagros J. (Springer Nature, 2017-12-21)
      Progress in understanding the complexity of a devastating disease such as cancer has underscored the need for developing comprehensive panels of molecular markers for early disease detection and precision medicine applications. ...
    • Cell cycle regulation by feed-forward loops coupling transcription and phosphorylation 

      Csikasz-Nagy, A.; Kapuy, O.; Toth, A.; Pal, C.; Jensen, L. J.; Uhlmann, F.; Tyson, John J.; Novak, B. (Nature Publishing Group, 2009-01-01)
    • Cell-cycle transitions: a common role for stoichiometric inhibitors 

      Hopkins, Michael; Tyson, John J.; Novak, Bela (2017-11-07)
      The cell division cycle is the process by which eukaryotic cells replicate their chromosomes and partition them to two daughter cells. To maintain the integrity of the genome, proliferating cells must be able to block ...
    • Cellulose digestion and assimilation by three leaf-shredding aquatic insects 

      Sinsabaugh, R. L.; Linkins, A. E.; Benfield, E. F. (Ecological Society of America, 1985)
