Effects of Soil Nutrients and Fire on Seedling Establishment of Native Prairie Species

Creator:: Clark, Deborah Louise, 1950-
Abstract:: We sought to determine 1) the relationship between seedling establishment rates of target native prairie species and field levels of three soil nutrients (phosphate, nitrate, and ammonium) recorded in fall, winter, and summer, 2) the effect of fire on these three nutrients, and 3) the overall effect of fire on...

The Genome of Tolypocladium inflatum: Evolution, Organization, and Expression of the Cyclosporin Biosynthetic Gene Cluster

Creator:: Bushley, Kathryn E., Raja, Rajani, Jaiswal, Pankaj, Cumbie, Jason S., Nonogaki, Mariko, Boyd, Alexander E., Owensby, C. Alisha, Knaus, Brian J., Elser, Justin, Miller, Daniel, Di, Yanming, McPhail, Kerry L., and Spatafora, Joseph W.
Abstract:: The ascomycete fungus Tolypocladium inflatum, a pathogen of beetle larvae, is best known as the producer of the immunosuppressant drug cyclosporin. The draft genome of T. inflatum strain NRRL 8044 (ATCC 34921), the isolate from which cyclosporin was first isolated, is presented along with comparative analyses of the biosynthesis of...

Mutualistic Co-evolution of Type III Effector Genes in Sinorhizobium fredii and Bradyrhizobium japonicum

Creator:: Kimbrel, Jeffrey A., Thomas, William J., Jiang, Yuan, Creason, Allison L., Thireault, Caitlin A., Sachs, Joel L., and Chang, Jeff H.
Abstract:: Two diametric paradigms have been proposed to model the molecular co-evolution of microbial mutualists and their eukaryotic hosts. In one, mutualist and host exhibit an antagonistic arms race and each partner evolves rapidly to maximize their own fitness from the interaction at potential expense of the other. In the opposing...

Testing the metabolic theory of ecology

Creator:: Price, Charles A., Weitz, Joshua S., Savage, Van M., Stegen, James, Clarke, Andrew, Coomes, David A., Dodds, Peter S., Etienne, Rampal S., Kerkhoff, Andrew J., McCulloh, Katherine, Niklas, Karl J., Olff, Han, and Swenson, Nathan G.
Abstract:: The metabolic theory of ecology (MTE) predicts the effects of body size and temperature on metabolism through considerations of vascular distribution networks and biochemical kinetics. MTE has also been extended to characterise processes from cellular to global levels. MTE has generated both enthusiasm and controversy across a broad range of...

Origins and evolution of viruses of eukaryotes: The ultimate modularity

Creator:: Koonin, Eugene V., Dolja, Valerian V., and Krupovic, Mart
Abstract:: Viruses and other selfish genetic elements are dominant entities in the biosphere, with respect to both physical abundance and genetic diversity. Various selfish elements parasitize on all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In prokaryotes, the great majority...

Simulated Evolution of Protein-Protein Interaction Networks with Realistic Topology

Creator:: Peterson, G. Jack, Pressé, Steve, Peterson, Kristin S., and Dill, Ken A.
Abstract:: We model the evolution of eukaryotic protein-protein interaction (PPI) networks. In our model, PPI networks evolve by two known biological mechanisms: (1) Gene duplication, which is followed by rapid diversification of duplicate interactions. (2) Neofunctionalization, in which a mutation leads to a new interaction with some other protein. Since many...

EvoDevo meets ecology: the Ninth Okazaki Biology Conference on Marine Biology

Creator:: Technau, Ulrich and Weis, Virginia M.
Abstract:: The “9th Okazaki Biology Conference: Marine Biology II” held at the National Institute for Basic Biology (NIBB) in Okazaki, Japan and at the Okinawa Institute of Science and Technology (OIST) in Okinawa, Japan (14–19 October 2012) bridged the fields of EvoDevo, symbiosis and coral reef ecology.

Eyespots deflect predator attack increasing fitness and promoting the evolution of phenotypic plasticity

Creator:: Prudic, Kathleen L., Stoehr, Andrew M., Wasik, Bethany R., and Monteiro, Antónia
Abstract:: Some eyespots are thought to deflect attack away from the vulnerable body, yet there is limited empirical evidence for this function and its adaptive advantage. Here, we demonstrate the conspicuous ventral hindwing eyespots found on Bicyclus anynana butterflies protect against invertebrate predators, specifically praying mantids. Wet season (WS) butterflies with...

The genome of the truffle-parasite Tolypocladium ophioglossoides and the evolution of antifungal peptaibiotics

Creator:: Quandt, C. Alisha, Bushley, Kathryn E., and Spatafora, Joseph W.
Abstract:: Background Two major mycoparasitic lineages, the family Hypocreaceae and the genus Tolypocladium, exist within the fungal order, Hypocreales. Peptaibiotics are a group of secondary metabolites almost exclusively described from Trichoderma species of Hypocreaceae. Peptaibiotics are produced by nonribosomal peptide synthetases (NRPSs) and have antibiotic and antifungal activities. Tolypocladium species are...

Biodiversity and ecology of lichens of Katmai and Lake Clark National Parks and Preserves, Alaska

Creator:: McCune, B., Arup, U., Breuss, O., Di Meglio, E., Di Meglio, J., Esslinger, T. L., Magain, N., Miadlikowska, J., Miller, A. E., Muggia, L., Nelson, P. R., Rosentreter, R., Schultz, M., Sheard, J. W., Tonsberg, T., and Walton, J.
Abstract:: We inventoried lichens in Lake Clark (LACL) and Katmai (KATM) National Parks and Preserves. We assembled the known information on lichens in these parks by combining field, herbarium, and literature studies. Our results provide baseline data on lichen occurrence that may be used in resource condition assessments, vulnerability assessments, long-term...
