Recent work has suggested that plants differ in their relative reliance on structural avoidance of embolism versus maintenance of the xylem water column through dynamic traits such as capacitance, but we still know little about how and why species differ along this continuum. It is even less clear how or...
Polyoxoniobates are exceptional amongst polyoxometalates in that
they can potentially perform base catalysis in water, a process in
which a proton is bonded to an oxo ligand, and a hydroxyl is
released. Catalytic decomposition of chemical warfare agents such
as organofluorophosphates that were used recently in the infamous
civilian attacks...
Western juniper (Juniperus occidentalis ssp.
occidentalis Hook) encroachment into mountain big sagebrush
(Artemisia tridentata spp. vaseyana (Rydb.) Beetle)
steppe has reduced livestock forage production, increased
erosion risk, and degraded sagebrush-associated wildlife
habitat. Western juniper has been successfully controlled
with partial cutting followed by prescribed burning the next
fall, but the...
Feedback loops involving soil microorganisms can
regulate plant populations. Here, we hypothesize that microorganisms
are most likely to play a role in plant–soil feedback
loops when they possess an affinity for a particular plant and
the capacity to consistently affect the growth of that plant for
good or ill. We...
Global electromagnetic (EM) induction studies have been the focus of increasing attention during the past few years. A primary stimulus for this interest has been increased quality, coverage and variety of the newly available data sets especially from recent low-Earth-orbiting satellite missions. The combination of traditional ground-based data with satellite-borne...
Discusses the benefits of having a management plan for your property. Describes how to prepare a management plan, including describing the property, setting goals, identifying resources, making recommendations, and keeping records. Includes additional sources for information.
Disease control of soilborne pathogens by biological control agents
(BCAs) is often inconsistent under field conditions. This inconsistency
may be partly influenced by pathogen diversity if there is a differential
response among pathogen species and isolates to selected BCAs. The
responses of 148 Pythium isolates obtained from soil at three...
We examined the multivariate life-history trajectories of age 0 and age 1 female Gambusia affinis to determine relative effects of age-based and environment-based cues on reproductive investment. Age 0 females decreased reproductive investment prior to the onset of fall and winter months, while age 1 females increased reproductive investment as...
