Assessing the drivers of adaptive radiation in a complex of gall midges: A multitrophic perspective on ecological speciation
… goldenrod (<i>Solidago</i>). This galler uses a symbiotic fungus (<i>Botryosphaeria dothidae</i>) as a food source and as the major structural component of its gall. Use of this symbiont may be the key innovation that allowed colonization of its host plant and began the process of adaptive …

Effects of Felled Shortleaf Pine (Pinus Echinata Mill.) Moisture Loss on Oviposition Preferences and Survival of Sirex Nigricornis F. (Hymenoptera: Siricidae)
… drill through pine bark to deposit eggs, a symbiotic fungus, <em>Amylostereum</em>, and phytotoxic mucus into the tree. In their native range, these insects are not viewed as primary pests because they attack dead or dying trees. Over the last century, this woodwasp has been accidentally …

Sensory Ecology of Carbon Dioxide Perception in Leaf-cutting Ants
… of CO2 are produced by the ants and their symbiotic fungus. Measurements in field nest at different depths revealed that CO2 concentrations do not exceed 2 per cent in mature nests. These findings indicate effective ventilation even at depths of 2 m. Small colonies often face the situation …

Biotic and Abiotic Characteristics Influencing Nest Location and Trophic Relationships of the Fungus-Growing Ant <i>Trachymyrmex septentrionalis</i> (Formicidae: <i>Attini)</i>
… represents the only species of fungus-growing ant in the southeastern United States. <em>T. septentrionalis </em>cultivates a symbiotic fungus on which the ants feed. Worker ants collect plant and animal debris to feed the fungus. These ants are common in Florida, but …
