Ecological speciation in phytophagous insects (2010, background): “Interspecific competition in insects has been documented, but its role in generating divergent selection between hosts has been less studied (Denno et al., 1995, 2002, 2003).”
Restoration of Arthropod Assemblages in a Spartina Salt Marsh following Removal of the Invasive Plant Phragmites australis (2005, background): “…Spartina habitats corresponded to areas that had no historical evidence of Phragmites invasion (back as far as 1955) and supported arthropod assemblages representative of pristine Spartina marshes found along the Atlantic coast (Davis & Gray 1966; Denno 1977; Döbel et al. 1990; Denno et al. 2003).”
Up or down in space? Uniting the bottom-up versus top-down paradigm and spatial ecology (2007, background): “By sharing common resources, herbivorous insects potentially compete with each other both at an intra- and an interspecific level (Denno et al. 2000, Ferrenberg and Denno 2003).”
Interactions between a hunting spider and a web‐builder: consequences of intraguild predation and cannibalism for prey suppression (2004, background): “Notably, Pardosa accumulates at very high densities in certain litter-rich habitats (> 500m 2) where it very effectively suppresses planthopper populations (Denno et al., 2002, 2003; Gratton & Denno, 2003).”
Stoichiometry of actual vs. potential predator–prey interactions: insights into nitrogen limitation for arthropod predators (2004, methodology): “This pattern likely results because the Spartina community is dominated by nitrogen poor sap-feeders such as planthoppers and leafhoppers that serve as the primary source of prey for many species of nitrogen-rich spiders (Döbel & Denno 1994; Denno et al. 2002, 2003).”
INTER-YEAR CARRYOVER EFFECTS OF A NUTRIENT PULSE ON SPARTINA PLANTS, HERBIVORES, AND NATURAL ENEMIES (2003, background): “Fertilization of Spartina has been shown to increase densities of herbivores such as planthoppers (Denno et al. 2002), mirids (Denno et al. 2003, Gratton and Denno 2003), and scale insects (Boyer and Zedler 1996) over the short term.”
