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...

Simulating dynein’s powerstroke using Brownian dynamics

Creator:: Capek, Elliott
Abstract:: Dynein is a motor protein which transports cargo along tracks inside the cell. Like related motor proteins kinesin and myosin, dynein uses cellular energy to take steps with its two foot domains. Unlike kinesin or myosin, dynein’s stepping pattern is highly varied: it can take steps between zero and 60nm...

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...

Convergent diversity and trait composition in temporary streams and ponds

Creator:: Schriever, Tiffany A. and Lytle, David A.
Abstract:: Hydrology is the main environmental filter in aquatic ecosystems and may result in shared tolerances and functional traits among species in disparate ecosystems. We analyzed the associations between taxonomic and functional facets of diversity within aquatic ecosystems (ponds vs. streams) across a hydroperiod gradient (1–365 d) to untangle the hydrologic...

Amplification and dampening of soil respiration by changes in temperature variability

Creator:: Sierra, C. A., Harmon, M. E., Thomann, E., Perakis, S. S., and Loescher, H. W.
Abstract:: Accelerated release of carbon from soils is one of the most important feedbacks related to anthropogenically induced climate change. Studies addressing the mechanisms for soil carbon release through organic matter decomposition have focused on the effect of changes in the average temperature, with little attention to changes in temperature variability....

A new species of Bembidion (Ecuadion) from Ecuador (Coleoptera, Carabidae, Bembidiini), with a key to members of the georgeballi species group

Creator:: Maddison, David R. and Toledano, Luca
Abstract:: A new species of ground beetle, Bembidion ricei, is described from the Andes mountains of Ecuador east of Quito. It belongs to the georgeballi species group of subgenus Ecuadion, and is most similar to Bembidion georgeballi. A key to the species of the group is provided.

Phylogeny of minute carabid beetles and their relatives based upon DNA sequence data (Coleoptera, Carabidae, Trechitae)

Creator:: Maddison, David R. and Ober, Karen A.
Abstract:: The phylogeny of ground beetles of supertribe Trechitae is inferred using DNA sequences of genes that code for 28S ribosomal RNA, 18S ribosomal RNA, and wingless. Within the outgroups, austral psydrines are inferred to be monophyletic, and separate from the three genera of true Psydrina (Psydrus, Nomius, Laccocenus); the austral...

Genetic Identification of Chinook Salmon: Stock-Specific Distributions of Juveniles along the Washington and Oregon Coasts

Creator:: Teel, David J., Burke, Brian J., Kuligowski, David R., Morgan, Cheryl A., and Van Doornik, Donald M.
Abstract:: We used microsatellite DNA data and genetic stock identification methods to delineate the temporal and spatial distributions of juvenile Chinook Salmon Oncorhynchus tshawytscha occupying coastal habitats extending from central Oregon to northern Washington. Juveniles were collected in trawl surveys conducted during spring, summer, and autumn over 15 years. Distributions (mean...

Ultraviolet Radiation Influences Perch Selection by a Neotropical Poison-Dart Frog

Creator:: Kats, Lee B., Bucciarelli, Gary M., Schlais, David E., Blaustein, Andrew R., and Han, Barbara A.
Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...
