How Effective Are DNA Barcodes in the Identification of African Rainforest Trees?

Creator:: Parmentier, Ingrid, Duminil, Jérôme, Kuzmina, Maria, Philippe, Morgane, Thomas, Duncan W., Kenfack, David, Chuyong, George B., Cruaud, Corinne, and Hardy, Olivier J.
Abstract:: Background: DNA barcoding of rain forest trees could potentially help biologists identify species and discover new ones. However, DNA barcodes cannot always distinguish between closely related species, and the size and completeness of barcode databases are key parameters for their successful application. We test the ability of rbcL, matK and...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

A Phylogenetic Perspective on the Individual Species- Area Relationship in Temperate and Tropical Tree Communities

Creator:: Yang, Jie, Swenson, Nathan G., Cao, Min, Chuyong, George B., Ewango, Corneille E. N., Howe, Robert, Kenfack, David, Thomas, Duncan, Wolf, Amy, and Lin, Luxiang
Abstract:: Ecologists have historically used species-area relationships (SARs) as a tool to understand the spatial distribution of species. Recent work has extended SARs to focus on individual-level distributions to generate individual species area relationships (ISARs). The ISAR approach quantifies whether individuals of a species tend have more or less species richness...

Post-fire tree establishment and early cohort development in conifer forests of the western Cascades of Oregon, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Early‐seral ecosystems make important contributions to regional biodiversity by supporting high abundance and diversity of many plant and animal species that are otherwise rare or absent from closed‐canopy forests. Therefore, the period of post‐fire tree establishment is a key stage in forest stand and ecosystem development that can be viewed...

Closing a gap in tropical forest biomass estimation: taking crown mass variation into account in pantropical allometries

Creator:: Ploton, Pierre, Barbier, Nicolas, Takoudjou Momo, Stéphane, Réjou-Méchain, Maxime, Boyemba Bosela, Faustin, Chuyong, Georges, Dauby, Gilles, Droissart, Vincent, Fayolle, Adeline, Goodman, Rosa Calisto, Henry, Matieu, Kamdem, Narcisse Guy, Mukirania, John Katembo, Kenfack, David, Libalah, Moses, Ngomanda, Alfred, Rossi, Vivien, Sonké, Bonaventure, Texier, Nicolas, Thomas, Duncan, Zebaze, Donatien, Couteron, Pierre, Berger, Uta, and Pélissier, Raphaël
Abstract:: Accurately monitoring tropical forest carbon stocks is a challenge that remains outstanding. Allometric models that consider tree diameter, height and wood density as predictors are currently used in most tropical forest carbon studies. In particular, a pantropical biomass model has been widely used for approximately a decade, and its most...

MTB-3, a Microtubule Plus-End Tracking Protein (+TIP) of Neurospora crassa

Creator:: Mourino-Perez, Rosa R., Linacre-Rojas, Lorena P., Roman-Gavilanes, Ariana I., Lew, Thomas K., Callejas-Negrete, Olga A., Roberson, Robert W., and Freitag, Michael
Abstract:: The microtubule (MT) "plus end" constitutes the platform for the accumulation of a structurally and functionally diverse group of proteins, collectively called "MT plus-end tracking proteins" (+TIPs). +TIPs control MT dynamics and link MTs to diverse sub-cellular structures. Neurospora crassa MicroTubule Binding protein-3 (MTB-3) is the homolog of yeast EB1,...

Evaluating Paratransgenesis as a Potential Control Strategy for African Trypanosomiasis

Creator:: Medlock, Jan, Atkins, Katherine E., Thomas, David N., Aksoy, Serap, and Galvani, Alison P.
Abstract:: Genetic-modification strategies are currently being developed to reduce the transmission of vector-borne diseases, including African trypanosomiasis. For tsetse, the vector of African trypanosomiasis, a paratransgenic strategy is being considered: this approach involves modification of the commensal symbiotic bacteria Sodalis to express trypanosome-resistance-conferring products. Modified Sodalis can then be driven into...

Predicting foundation bunchgrass species abundances: model-assisted decision-making in protected-area sagebrush steppe

Creator:: Rodhouse, Thomas J., Irvine, Kathryn M., Sheley, Roger L., Smith, Brenda S., Hoh, Shirley, Esposito, Daniel M., and Mata-Gonzalez, Ricardo
Abstract:: Foundation species are structurally dominant members of ecological communities that can stabilize ecological processes and influence resilience to disturbance and resistance to invasion. Being common, they are often overlooked for conservation but are increasingly threatened from land use change, biological invasions, and over‐exploitation. The pattern of foundation species abundances over...

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...

Differential surface activation of the A1 domain of von Willebrand factor

Creator:: Tronic, Elaine H., Yakovenko, Olga, Weidner, Tobias, Baio, Joe E., Penkala, Rebecca, Castner, David G., and Thomas, Wendy E.
Abstract:: The clotting protein von Willebrand factor (VWF) binds to platelet receptor glycoprotein Ibα (GPIbα) when VWF is activated by chemicals, high shear stress, or immobilization onto surfaces. Activation of VWF by surface immobilization is an important problem in the failure of cardiovascular implants, but is poorly understood. Here, the authors...
