Severe Drought Drives Novel Community Trajectories in Desert Stream Pools

Creator:: Bogan, Michael T. and Lytle, David A.
Abstract:: 1. Ecological communities can be relatively stable for long periods of time, and then, often as a result of disturbance, transition rapidly to a novel state. When communities fail to recover to pre-disturbance configurations, they are said to have experienced a regime shift or to be in an alternative stable state....

Broad-scale patterns of invertebrate richness and community composition in temporary rivers : effects of flow intermittence

Creator:: Datry, T., Larned, S. T., Fritz, K. M., Bogan, M. T., Wood, P. J., Meyer, E. I., and Santos, A. N.
Abstract:: Temporary rivers are increasingly common freshwater ecosystems, but there have been no global syntheses of their community patterns. In this study, we examined the responses of aquatic invertebrate communities to flow intermittence in 14 rivers from multiple biogeographic regions covering a wide range of flow intermittence and spatial arrangements of...

Acid-sensing ion channels in mouse olfactory bulb M/T neurons

Creator:: Li, Ming-Hua, Liu, Selina Qiuying, Inoue, Koichi, Lan, Jinquan, Simon, Roger P., and Xiong, Zhi-Gang
Abstract:: The olfactory bulb contains the first synaptic relay in the olfactory pathway, the sensory system in which odorants are detected enabling these chemical stimuli to be transformed into electrical signals and, ultimately, the perception of odor. Acid-sensing ion channels (ASICs), a family of proton-gated cation channels, are widely expressed in...

Arrhinolemur scalabrinii Ameghino, 1898, of the late Miocene - a taxonomic journey from the Mammalia to the Anostomidae (Ostariophysi: Characiformes)

Creator:: Bogan, Sergio, Sidlauskas, Brian, Vari, Richard P., and Agnolin, Federico
Abstract:: The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order Arrhinolemuroidea within the Mammalia, our analysis indicates that the specimen is rather a...

Linking multidimensional functional diversity to quantitative methods: a graphical hypothesis-evaluation framework

Creator:: Boersma, Kate S., Dee, Laura E., Miller, Steve J., Bogan, Michael T., Lytle, David A., and Gitelman, Alix I.
Abstract:: Functional trait analysis is an appealing approach to study differences among biological communities because traits determine species' responses to the environment and their impacts on ecosystem functioning. Despite a rapidly expanding quantitative literature, it remains challenging to conceptualize concurrent changes in multiple trait dimensions (“trait space”) and select quantitative functional...

Dispersal strength determines meta-community structure in a dendritic riverine network

Creator:: Cañedo-Argüelles, Miguel, Boersma, Kate S., Bogan, Michael T., Olden, Julian D., Phillipsen, Ivan, Schriever, Tiffany A., and Lytle, David A.
Abstract:: AIM: Meta-community structure is a function of both local (site-specific) and regional (landscape-level) ecological factors, and the relative importance of each may be mediated by the dispersal ability of organisms. Here, we used aquatic invertebrate communities to investigate the relationship between local and regional factors in explaining distance decay relationships...

Lipid/bitumen maturation by hydrothermal activity in sediments of Middle Valley, leg 139

Creator:: Simoneit, Bernd R. T.
Abstract:: The accelerated diagenesis, maturation, and catagenesis of organic matter to hydrothermal petroleum was studied in sediments from Ocean Drilling Program Leg 139 in Middle Valley, northern Juan de Fuca Ridge. Sediments at Sites 855 and 856 have experienced high heat flow resulting in accelerated diagenesis of the immature organic matter...

Sediment depths determined by comparison of grape and logging denisty data during Leg 138

Creator:: Mix, Alan C., Harris, Sara E., Hagelberg, T. K., Pisias, Nicklas G., and Shackleton, N. J.
Abstract:: Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...

Abstract:: High resolution, continuous records of GRAPE wet bulk density (a carbonate proxy) from Ocean Drilling Program Leg 138 provide one the opportunity for a detailed study of eastern equatorial Pacific Ocean carbonate sedimentation during the last 6 m.y. The transect of sites drilled spans both latitude and longitude in the...

Dissolved organic carbon in interstitial waters from sediments of Middle Valley, leg 139

Creator:: Ran, Baiyun and Simoneit, Bernd R. T.
Abstract:: High-temperature combustion oxidation measurements of nonvolatile dissolved organic carbon (DOC) have been determined for pore waters from sediments of Middle Valley, Ocean Drilling Program Leg 139, as well as for overlying and near-bottom seawater. The DOC values in the interstitial waters are generally greater than those in the overlying water...
