    • Effects of above-ground herbivory on soil microbial biomass in conventional and no-tillage agroecosystems 

      Holland, J Nat (1995)
      The effects of above-ground herbivory on soil microbial biomass associated with maize (Zea muys) roots were measured in field experiments. Different grazing intensities were established by placing grasshoppers (0, 5, 10 ...
    • Evaluating effects of habitat loss, hunting, and El Niño on a threatened lemur 

      Erhart, Elizabeth M.; Dunham, Amy E.; Wright, Patricia C.; Overdorff, Deborah J. (2008)
      Madagascar ranks as one of the world’s top extinction hotspots because of its high endemism and high rate of habitat degradation. Global climate phenomena such as El Nin˜ o Southern Oscillations may have confounding ...

      Zhu, Yun; Lin, Zhenguo; Nakhleh, Luay (9/18/2013)
      Gene duplication plays an important role in the evolution of genomes and interactomes. Elucidating how evolution after gene duplication interplays at the sequence and network level is of great interest. In this paper, we ...
    • The evolution of obligate pollination mutualisms: senita cactus and senita moth 

      Holland, J. Nathaniel; Fleming, Theodore H. (1998)
      We report a new obligate pollination mu- tualism involving the senita cactus, Lophocereus schottii (Cactaceae, Pachyceereae), and the senita moth, Upiga virescens (Pyralidae, Glaphyriinae) in the Sonoran De- sert and ...
    • Experimental evidence that both parties benefit in a facultative plant-spider mutualism 

      Whitney, Kenneth D (2004-06)
      Spiders are known to influence plant fitness, and vice versa. Yet, it has not been appreciated that these facultative relationships can be mutualistic. I examined the interaction between Phryganoporus candidus, a subsocial ...

      Myriapods (e.g., centipedes and millipedes) display a simple homonomous body plan relative to other arthropods. All members of the class are terrestrial, but they attained terrestriality independently of insects. Myriapoda ...
    • Fungal Symbionts as Manipulators of Plant Reproductive Biology 

      Gorischek, Alexander M.; Afkhami, Michelle E.; Seifert, Elizabeth K.; Rudgers, Jennifer A. (2013-04)
      Symbioses have shaped the evolution of life, most notably through the fixation of heritable symbionts into organelles. The inheritance of symbionts promotes mutualism and fixation by coupling partner fitness. However, ...
    • Genetic variation in anti-herbivore chemical defences in an invasive plant 

      Wang, Yi; Siemann, Evan; Wheeler, Gregory S.; Zhu, Lin; Gu, Xue; Ding, Jianqing (2012)
    • The Genome of the Ctenophore Mnemiopsis leidyi and Its Implications for Cell Type Evolution 

      Ryan, Joseph F.; Pang, Kevin; Schnitzler, Christine E.; Nguyen, Anh-Dao; Moreland, R. Travis; Simmons, David K.; Koch, Bernard J.; Francis, Warren R.; Havlak, Paul; NISC Comparative Sequencing Program; Smith, Stephen A.; Putnam, Nicholas H.; Haddock, Steven H.D.; Dunn, Casey W.; Wolfsberg, Tyra G.; Mullikin, James C.; Martindale, Mark Q.; Baxevanis, Andreas D. (2013)
      An understanding of ctenophore biology is critical for reconstructing events that occurred early in animal evolution. Toward this goal, we have sequenced, assembled, and annotated the genome of the ctenophore Mnemiopsis ...
    • Geographic and population variation in pollinating seed-consuming interactions between senita cacti (Lophocereus schottii) and senita moths (Upiga virescens) 

      Fleming, Theodore H.; Holland, J. Nathaniel (1999)
      Interspecific interactions can vary within and among populations and geographic locations. This variation can subsequently influence the evolution and coevolution of species interactions. We investigated population and ...
    • Ghosts of Habitats Past: Environmental Carry-Over Effects Drive Population Dynamics in Novel Habitat 

      Van Allen, Benjamin G.; Rudolf, Volker H.W. (2013-05)
      The phenotype of adults can be strongly influenced by the environmental conditions experienced during development. Consequently, variation in habitat quality across space and through time also leads to differences in the ...

      Liu, Kevin J.; Dai, Jingxuan; Truong, Kathy; Song, Ying; Kohn, Michael H.; Nakhleh, Luay (6/12/2014)
      One outcome of interspecific hybridization and subsequent effects of evolutionary forces is introgression, which is the integration of genetic material from one species into the genome of an individual in another species. ...
    • Insect seed predators as novel agents of selection on fruit color 

      Stanton, Maureen L; Whitney, Kenneth D (2004-08)
      The ecological and evolutionary dynamics of fruit color polymorphisms remain poorly known because patterns and agents of selection have rarely been identified. Here, we examine Acacia ligulata, a shrub of the Australian ...
    • Intraspecific priority effects and disease interact to alter population growth 

      Dibble, Christopher J.; Hall, Spencer R.; Rudolf, Volker H.W. (2014)
      Intraspecific variation may shape colonization of new habitat patches through a variety of mechanisms. In particular, trait variation among colonizing individuals can produce intraspecific priority effects (IPEs), where ...

      Nossa, Carlos W.; Havlak, Paul; Yue, Jia-Xing; Lv, Jie; Vincent, Kimberly Y.; Brockmann, H. Jane; Putnam, Nicholas H. (2014)
      Horseshoe crabs are marine arthropods with a fossil record extending back approximately 450 million years. They exhibit remarkable morphological stability over their long evolutionary history, retaining a number of ancestral ...
