Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal...
With many ecosystems now supporting multiple nonnative species from different trophic levels, it can be challenging to disentangle the net effects of invaders within a community context. Here, we combined wetland surveys with a mesocosm experiment to examine the individual and combined effects of nonnative fish predators and nonnative bullfrogs...
Flavin-containing monooxygenase (FMO) oxygenates drugs/xenobiotics containing a
soft nucleophile through a C4a hydroperoxy-FAD intermediate. Human FMOs 1, 2 and
3, expressed in Sf9 insect microsomes, released 30-50% of O₂ consumed as H₂O₂
upon addition of NADPH. Addition of substrate had little effect on H₂O₂ production.
Two common FMO2 (the major...
In the late 1850s, few young Jews, recently arrived in the United States from Poland, chose to live in Florida. Fortunately, one who did, Max White, wrote down his memoirs of those years, leaving us a remarkable, very personal account of life on the Florida frontier as well as a...
Community structure and function in ecosystems are dependent on top‐down and bottom‐up factors, which vary across local, regional, and temporal scales. In estuaries of the U.S. Pacific Northwest coast, eelgrass (Zostera marina) ecosystems are exposed to latitudinally varying oceanographic inputs in the form of ocean upwelling. Previous research suggests that...
The amount and type of carbon (C) in a forest soil reflects the past balance between C accumulation and loss. In an old-growth forest soil, C is thought to be in dynamic equilibrium between accumulations and losses. Disturbance upsets this equilibrium by altering the microclimate, the amount and type of...
AIM: Landscape management and conservation planning require maps of vegetation
composition and structure over large regions. Species distribution models
(SDMs) are often used for individual species, but projects mapping multiple species
are rarer. We compare maps of plant community composition assembled by
stacking results from many SDMs with multivariate maps...
