Changes in soil C and N pools following wildfire are
quite varied, but there is little understanding of the
causes of the variation. We examined how the
legacies of prefire ecosystem structure may explain
the variation in soil trajectories during the first
decade following wildfire. Five years prior to

Early-successional stages have been truncated and altered in many western U.S. forest landscapes by
planting conifers, controlling competing vegetation, suppressing fire, and focusing on maintaining late-seral
species and undisturbed riparian zones. Declining area of early-successional stages may be reducing
resilience and sustainability on landscapes that experience elevated disturbance related to...

We use autonomous gas measurements to examine the metabolic balance (photosynthesis
minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations
capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and
biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...

Hybridization has been identified as a significant factor in the evolution of plants as groups of interbreeding species retain their phenotypic integrity despite gene exchange among forms. Recent studies have identified similar interactions in animals; however, the role of hybridization in the evolution of animals has been contested. Here we...

Four decades after the passage of the US Clean Air Act, air-quality standards are set to protect ecosystems from damage caused by gas-phase nitrogen (N) and sulfur (S) compounds, but not from the deposition of these air pollutants to land and water. Here, we synthesize recent scientific literature on the...

We have recently reported that cell-penetrating peptides (CPPs) and novel chimeric peptides containing CPP (referred as
B peptide) and muscle-targeting peptide (referred as MSP) motifs significantly improve the systemic exon-skipping activity
of morpholino phosphorodiamidate oligomers (PMOs) in dystrophin-deficient mdx mice. In the present study, the general
mechanistic significance of the...
