Abstract: Long time series of sea surface height (SSH), sea surface temperature, and wind stress curl are used to determine the main modes of low-frequency variability of the Southern Ocean (SO) circulation. The dominant mode is a trend of increasing SSH at an average rate of 3.3 mm yr(-1). Similar...
Abstract: Tide-topography interactions dominate the transfer of tidal energy from large to small scales. At present, it is poorly understood how low-mode internal tides reflect and scatter along the continental margins. Here, the coupling equations for linear tides model (CELT) are derived to determine the independent modal solutions to Laplace's...
Abstract: We prove that for all ergodic extensions S-1 of a transformation by a locally compact second countable group G, and for all G-extensions S₂ of an aperiodic transformation, there is a relative speedup of S₁ that is relatively isomorphic to S₂. We apply this result to give necessary and...
Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems
and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide
Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean
ecosystems. Changes in the surface chlorophyll concentration, the primary...
In western conifer-dominated forests where the abundance of old-growth stands is decreasing, species
such as the Brown Creeper (Certhia americana) may be useful as indicator species for monitoring the health
of old-growth systems because they are strongly associated with habitat characteristics associated with old growth
and are especially sensitive to...
In the current research we tested a comprehensive model of spirituality, religiosity, compassion, and altruism, investigating the independent effects of spirituality and religiosity on compassion and altruism. We hypothesized that, even though spirituality and religiosity are closely related, spirituality and religiosity would have different and unique associations with compassion and...
Transcriptome analysis of Pseudomonas fluorescensSBW25 showed that 702 genes were differentially regulated in a gacS::Tn5 mutant, with 300 and 402 genes up- and downregulated respectively. Similar to the Gac regulon of other Pseudomonas species, genes involved in motility, biofilm formation, siderophore biosynthesis and oxidative stress were differentially regulated in the...
Swiss needle cast (SNC), an important fungal disease of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), has increased in severity throughout its natural and introduced range over the last half century. The role of climate change and forest management practices in the increase is unclear. We analyzed tree-ring chronologies from six late-successional...
The Myristicaceae is a member of the early diverging angiosperm order Magnoliales, however the family is poorly represented by fossil collections. We describe Virola dominicana sp. nov. (Myristicaceae), the first record of fossilized Myristicaceae flowers, from mid-Tertiary (45-15 mya) Dominican amber. The description is based on 24 male flowers in...
