Integrating precipitation, grazing, past effects and interactions in long-term vegetation change

Creator:: Morris, Christo, Badik, Kevin J., Morris, Lesley R., and Weltz, Mark A.
Abstract:: Determining the causes of vegetation change in arid and semi-arid environments can be difficult and may involve multiple factors, including disturbance, inter-annual climatic variation, soils, effects from years past and interactions between these factors. Theoretical models describing vegetation change in these systems have generally focused on a single aspect as...

Intragenomic polymorphisms among high-copy loci: a genus-wide study of nuclear ribosomal DNA in Asclepias (Apocynaceae)

Creator:: Weitemier, Kevin, Straub, Shannon C. K., Fishbein, Mark, and Liston, Aaron
Abstract:: Despite knowledge that concerted evolution of high-copy loci is often imperfect, studies that investigate the extent of intragenomic polymorphisms and comparisons across a large number of species are rarely made. We present a bioinformatic pipeline for characterizing polymorphisms within an individual among copies of a high-copy locus. Results are presented...

Hyb-Seq: Combining target enrichment and genome skimming for plant phylogenomics

Creator:: Weitemier, Kevin, Straub, Shannon C. K., Cronn, Richard C., Fishbein, Mark, Schmickl, Roswitha, McDonnell, Angela, and Liston, Aaron
Abstract:: PREMISE OF THE STUDY: Hyb-Seq, the combination of target enrichment and genome skimming allows simultaneous data collection for low-copy nuclear genes and high-copy genomic targets for plant systematics and evolution studies. METHODS AND RESULTS: Genome and transcriptome assemblies for milkweed (Asclepias syriaca) were utilized to design enrichment probes for 3385...

Density dependence and population regulation in marine fish: a large-scale, long-term field manipulation

Creator:: Hixon, Mark A., Anderson, Todd W., Buch, Kevin L., Johnson, Darren W., McLeod, J. Brock, and Stallings, Christopher D.
Abstract:: dependence and regulation of relatively large local populations? If so, what are the causative mechanisms and their implications? We conducted an eight-year multigeneration study of population dynamics of bicolor damselfish (Stegastes partitus) inhabiting four large coral reefs in the Bahamas. After a four-year baseline period, it was clear that two...

The New Age of Hyperspectral Oceanography

Creator:: Chang, Grace, Mahoney, Kevin, Briggs-Whitmire, Amanda, Kohler, David, Mobley, Curtis, Lewis, Marlon, Moline, Mark, Boss, Emmanuel, Kim, Minsu, Philpot, William, and Dickey, Tommy
Abstract:: A multispectral optical sensor collects data at select wavebands or channels. An example is the Sea-viewing Wide-Field-of-view Sensor (SeaWiFS) ocean color satellite, which measures eight wavebands between 402 and 885 nm (20-40 nm bandwidth with peaks centered around 412, 443, 490, 510, 555, 670, 765, and 865 nm). Optical oceanographers...

Toward autonomous measurements of photosynthetic electron transport rates: An evaluation of active fluorescence-based measurements of photochemistry

Creator:: Silsbe, Greg M., Oxborough, Kevin, Suggett, David J., Forster, Rodney M., Ihnken, Sven, Komárek, Ondřej, Lawrenz, Evelyn, Prášil, Ondřej, Röttgers, Rüdiger, Šicner, Michal, Simis, Stefan G. H., Van Dijk, Mark A., and Kromkamp, Jacco C.
Abstract:: This study presents a methods evaluation and intercalibration of active fluorescence-based measurements of the quantum yield (ϕ'ₚₛᵢᵢ) and absorption coefficient (aₚₛᵢᵢ) of photosystem II (PSII) photochemistry. Measurements of ϕ'ₚₛᵢᵢ, aₚₛᵢᵢ, and irradiance (E) can be scaled to derive photosynthetic electron transport rates (Pₑ), the process that fuels phytoplankton carbon fixation...

Reconciling Conflicting Phylogenies in the Origin of Sweet Potato and Dispersal to Polynesia

Creator:: Muñoz-Rodríguez, Pablo, Carruthers, Tom, Wood, John R.I., Williams, Bethany R.M., Weitemier, Kevin, Kronmiller, Brent, Ellis, David, Anglin, Noelle L., Longway, Lucas, Harris, Stephen A., Rausher, Mark D., Kelly, Steven, Liston, Aaron, and Scotland, Robert W.
Abstract:: The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...

Combined treatment of rapamycin and dietary restriction has a larger effect on the transcriptome and metabolome of liver

Creator:: Fok, Wilson C., Bokov, Alex, Gelfond, Jonathan, Yu, Zhen, Zhang, Yiqiang, Doderer, Mark, Chen, Yidong, Javors, Martin, Wood, William H., III, Zhang, Yongqing, Becker, Kevin G., Richardson, Arlan, and Pérez, Viviana I.
Abstract:: Rapamycin (Rapa) and dietary restriction (DR) have consistently been shown to increase lifespan. To investigate whether Rapa and DR affect similar pathways in mice, we compared the effects of feeding mice ad libitum (AL), Rapa, DR, or a combination of Rapa and DR (Rapa + DR) on the transcriptome and...

Enteromius pinnimaculatus (Cypriniformes: Cyprinidae), a new species from Southern Gabon

Creator:: Mipounga, Hans Kevin, Cutler, Joseph, Mve Beh, Jean Hervé, Adam, Benjamin, and Sidlauskas, Brian L.
Abstract:: With more than 407 species of freshwater and brackish water fishes, Gabon is a country rich in ichthyological biodiversity, but its aquatic environments remain poorly explored. We present and describe a new species of Enteromius, adding to the 16 species of Enteromius currently recorded from that country. This new species...
