FAGAN, W.F.; SIEMANN, E; MITTER, C.M.; DENNO, R.F.; HUBERTY, A.F.; WOODS, H.A.; University of Maryland; Rice University; University of Maryland; University of Maryland; University of Maryland; University of Texas: Nitrogen in insects: Implications for trophic complexity and species diversification Disparities in nutrient content (nitrogen and phosphorus) between herbivores and their plant resources have lately proven […]

HARRISON, J.F.*; WOODS, H.A.; FAY, M.L.; PERKINS, M.C.; Arizona State University, Tempe; Univ. of Texas, Austin; Arizona State University, Tempe; Orange Coast College, Costa Mesa: Is phosphate an important nutrient influencing the growth, physiology and behavior of herbivorous insects, or a generally overabundant micronutrient? Studies of the nutritional ecology of herbivorous insects have focused on […]

ELSER, JJ; Arizona State University: Biological stoichiometry from genes to ecosystems: ideas, plans, and realities Biological stoichiometry is the study of the balance of energy and multiple chemical elements in living systems. This approach grows out of work in the arena of aquatic ecosystem science but in our ongoing IRCEB project we are extending these […]

COTNER, J.B.*; MAKINO, W.; HALL, E.K.; Univ. Minnesota- Twin Cities; Kyoto University; Univ. Minnesota- Twin Cities: Biological stoichiometry: From bacteria to ecosystems to global change The growth rate of an organism has been described as a master variable that regulates intra-organismal and intra-cellular processes, but it is also responsive to environmental cues. Therefore, much of […]

LOVEJOY, N; University of Manitoba: Phylogeny and Ontogeny of Needlefishes Heterochrony, defined as evolutionary change in ontogenetic timing, can play an important role in morphological innovation. However, the relative importance of paedomorphosis and peramorphosis remains unclear. The beloniform fishes, including needlefishes, halfbeaks, flyingfishes, ricefishes, and sauries, have long been considered examplars of paedomorphosis. As needlefishes […]

PERES-NETO, Pedro R.; University of Quebec at Trois-Rivieres: Patterns in the co-occurrence of fish species in streams: the role of site suitability, morphology and phylogeny versus species interactions A number of studies at large scales have pointed out that abiotic factors and recolonization dynamics appear to be more important in structuring stream-fish assemblages than biotic […]

SANTINI, F.*; YBAZETA, G.; University of Toronto; University of Toronto: Patterns and processes in the evolution of fishes: an introduction to the symposium Fishes comprises over 50% of all described species of vertebrates. They are present in, and constitute a large part of, the biodiversity of every aquatic ecosystem, and often play a dominant ecological […]

CHOUDHURY, A*; PEREZ-PONCE DE LEON, G; St. Norbert College, DePere; Universidad Nacional Autonoma de Mexico, Mexico D.F.: Parascript studies and the historical biogeography of North American freshwater fishes The historical biogeography of enduring associations between North American freshwater fishes and their metazoan parasites is explored in the tradition of parascript studies (using the language of […]

ARRATIA,, G.; Museum fuer Naturkunde, 10115 Berlin, Germany. gloria.arratia@rz.hu-berlin.de: Origin and Early Radiation of Teleostei The Telesotei and its sister-group the Halecomorphi are currently included in the Division Halecostomi. During the last 30 years, fundamental work concerning the monophyly of the Teleostei, as well as of the Halecomorphi, and the phylogenetic relationships among halecostome subgroups […]
