Multiple sediment cores were used to address how metals contamination and eutrophication has changed over the last 200 years in the Great Salt Lake. The cores from Gilbert and Farmington Bay were sectioned in 0.5-cm intervals, and analyzed for...

Farmington Bay, is a large (100 mi2; 260 km2) and very shallow (mean depth ~3 ft) embayment at the SE corner of the Great Salt Lake, bordering greater metropolitan Salt Lake City. The embayment is largely enclosed by an automobile causeway so that...

Farmington Bay is a hypereutrophic embayment of the Great Salt Lake. Monitoring of brine shrimp (Artemia franciscana Kellogg) populations had indicated that brine shrimp densities in Farmington Bay are only 61% of those in the Great Salt Lake....

In September 2012 the Aquatic Ecology Practicum class from Utah State University studied the 51km river continuum of the Little Bear River located in northern Utah (Figure 1). The relatively pristine headwaters of the river begin in the Wasatch...

Deep chlorophyll layers (DCL) are a common feature of oligotrophic lakes, yet the mechanisms that form and maintain them are not understood fully. These phytoplankton populations occur in the metalimnia of lakes where light levels are moderate to...

The limnology of Jackson Lake has been studied very little, despite the fact that it is the uppermost large lake on the headwaters of the Snake River, one of the larger rivers in the country (Hayden 1969). It is also an important fishery, largely...

Natural geography and causeways have divided the Great Salt Lake into four bays with limited, but important connections. Most pollutants from cities in Utah flow into Farmington Bay, and to a lesser extent, into Bear River Bay before entering...

Salinity is a driving force for change in hypersaline community structure. The Great Salt Lake is populated at high salinities by the salt-tolerant brine shrimp (Artemia Franciscana) and brine fly (Ephydra gracilis), and lake management decisions...

Farmington Bay of Great Salt Lake has been studied extensively over the last two decades and observations indicate high levels of both nutrients and the toxic cyanobacteria Nodularia spumigena. During 2012-2013 we measured the physical, chemical,...

• Premise of the study: The characteristics of clonal growth that are advantageous in invasive plants can also result in native plants’ ability to resist invasion. In Maine, we compared the clonal architecture and diversity of an invasive lineage...

Studies on invasive plant management are often short in duration and limited in the methods tested, and lack an adequate description of plant communities that replace the invader following removal. Here we present a comprehensive review of...

Physiological ecology and plant functional traits are often used to explain plant invasion. To gain a better understanding of how traits influence invasion, studies usually compare the invasive plant to a native congener, but there are few...

Background and Aims Mediterranean forests are vulnerable to numerous threats including wildfires due to a combination of climatic factors and increased urbanization. In addition, increased temperatures and summer drought lead to increased risk of...

We tested the performance of Plant Root Simulator (PRS) probes as a tool to determine plant nutrient availability across the semiarid environments of the central Rocky Mountains. We used PRS probes in a lab-field comparison representing the...

The concepts of diagnostic species and fidelity have been used frequently in European phytosociology but rarely in North American vegetation classification. We developed a classification of the vegetation of a mountainous area of northern Utah and...

This study compares the amount, distribution, and stability of soil organic carbon (SOC) in six paired quaking aspen (Populus tremuloides Michx) and conifer plots at three locations in northern Utah, to assess the influence of vegetation cover and...

Enhancement of forest growth through silvicultural modification of stand density is one strategy for increasing carbon (C) sequestration. Using the Fire and Fuels Extension of the Forest Vegetation Simulator, the effects of even-aged, uneven-aged...

We compared soil organic carbon (SOC) stocks and stability under two widely distributed tree species in the Mediterranean region: Scots pine (Pinus sylvestris L.) and Pyrenean oak (Quercus pyrenaica Willd.) at their ecotone. We hypothesised that...

Near-infrared reflectance spectroscopy (NIRS) and partial least squares regression were used to develop prediction models for identifying the species of origin of soil organic C (SOC) in semiarid montane forests of quaking aspen (Populus...

To assess the potential impact of conifer encroachment on soil organic carbon (SOC) dynamics and storage in montane aspen-conifer forests from the interior western US, we sampled mineral soils (0–15 cm) across the aspen-conifer ecotones in...

A meta-analysis using 77 studies from 28 countries was performed to assess the effect of hardwood vs. conifer overstory on soil organic C (SOC) storage in forest floor (FF), mineral soil, and whole soil (FF + mineral soil). Overall, FF stocks were...

In this chapter we summarize current state-of-knowledge on the impact of natural and anthropogenic disturbances on SOC stocks and CO2 emissions from forest soils. We consider the relative impact of various harvesting regimes that differ on...

Mountain areas in Europe have been experiencing greater changes in climate over the last century than other European landscapes. This considerable shift in the climate towards warmer conditions together with substantial labile soil carbon stocks...
