    • Contrasting responses within a single neuron class enable sex-specific attraction in Caenorhabditis elegans 

      Narayan, Anusha; Venkatachalam, Vivek; Durak, Omer; Reilly, Douglas K.; Bose, Neelanjan; Schroeder, Frank C.; Samuel, Aravinthan DT; Srinivasan, Jagan; Sternberg, Paul W. (Proceedings of the National Academy of Sciences, 2016)
      Animals find mates and food, and avoid predators, by navigating to regions within a favorable range of available sensory cues. How are these ranges set and recognized? Here we show that male Caenorhabditis elegans exhibit ...

    • Effects of the Distribution of Female Primates on the Number of Males 

      Carnes, Laurel Mariah; Nunn, Charles Lindsay; Lewis, Rebecca J. (Public Library of Science, 2011)
      The spatiotemporal distribution of females is thought to drive variation in mating systems, and hence plays a central role in understanding animal behavior, ecology and evolution. Previous research has focused on investigating ...

    • General Intelligence in Another Primate: Individual Differences across Cognitive Task Performance in a New World Monkey (Saguinus Oedipus) 

      Tsao, Fritz; Banerjee, Konika; Chabris, Christopher F; Johnson, Valen E.; Lee, James J.; Tsao; Hauser, Marc David (Public Library of Science, 2009)
      Background: Individual differences in human cognitive abilities show consistently positive correlations across diverse domains, providing the basis for the trait of “general intelligence” (g). At present, little is known ...

    • The Genetic Signature of Sex-Biased Migration in Patrilocal Chimpanzees and Humans 

      Langergraber, Kevin E.; Siedel, Heike; Mitani, John C.; Reynolds, Vernon; Hunt, Kevin; Vigilant, Linda; Wrangham, Richard W. (Public Library of Science, 2007)
      A large body of theoretical work suggests that analyses of variation at the maternally inherited mitochondrial (mt)DNA and the paternally inherited non-recombining portion of the Y chromosome (NRY) are a potentially powerful ...

    • Molecular Organization of Vomeronasal Chemoreception 

      Isogai, Yoh; Si, Sheng; Pont-Lezica, Lorena; Tan, Taralyn Marie; Kapoor, Vikrant; Murthy, Venkatesh N.; Dulac, Catherine (Nature Publishing Group, 2011)
      The vomeronasal organ (VNO) has a key role in mediating the social and defensive responses of many terrestrial vertebrates to species- and sex-specific chemosignals. More than 250 putative pheromone receptors have been ...

    • The mystery of language evolution 

      Hauser, Marc D.; Yang, Charles; Berwick, Robert C.; Tattersall, Ian; Ryan, Michael J.; Watumull, Jeffrey; Chomsky, Noam; Lewontin, Richard C. (Frontiers Media S.A., 2014)
      Understanding the evolution of language requires evidence regarding origins and processes that led to change. In the last 40 years, there has been an explosion of research on this problem as well as a sense that considerable ...

    • Neurobiology of Caenorhabditis elegans Locomotion: Where Do We Stand? 

      Gjorgjieva, Julijana; Biron, David; Haspel, Gal (Oxford University Press, 2014)
      Animals use a nervous system for locomotion in some stage of their life cycle. The nematode Caenorhabditis elegans, a major animal model for almost all fields of experimental biology, has long been used for detailed studies ...

    • Spatial Pattern Enhances Ecosystem Functioning in an African Savanna 

      Pringle, Robert Mitchell; Doak, Daniel F.; Brody, Alison K.; Jocqué, Rudy; Palmer, Todd M. (Public Library of Science, 2010)
      The finding that regular spatial patterns can emerge in nature from local interactions between organisms has prompted a search for the ecological importance of these patterns. Theoretical models have predicted that ...
