This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: To assess the interactive effects of prescribed fire on small mammals in these altered ecosystems, we performed a randomized experiment where we applied prescribed fire on 36 of 54 plots. The effects of fire on many small mammal populations and the composition of the small mammal community varied along the invasion gradient, suggesting that fire functions differently in areas dominated by nonnative plants relative to those dominated by native plants. Invasion by this nonnative grass has clearly shifted the composition of faunal communities in semi-desert grasslands and has altered ecosystem processes, therefore reestablishing fire is not likely to be an omnibus solution for restoration.

Book Synopsis Cheatgrass Invasion of Sagebrush Steppe by : Daniel Allen Bachen
Download or read book Cheatgrass Invasion of Sagebrush Steppe written by Daniel Allen Bachen and published by . This book was released on 2014 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonnative plants can affect habitat quality for native animals directly, through changes in resources like cover or food, and indirectly, through changes in access to resources or predation risk. Understanding these effects is crucial to develop management techniques and maintain ecosystem processes. In sagebrush steppe, brome grasses such as cheatgrass (Bromus tectorum) can invade and form dense stands, increasing the depth and persistence of litter, as well as the density of standing vegetation. These structural changes alter abundance and composition of the small mammal community. We used a series of experiments to explore whether changes in vegetation structure associated with the invasion of cheatgrass would alter foraging and predation risk of small mammals, to better understand mechanisms driving documented population- and community-level effects. In the first experiment, we placed a measured amount of grain at stations with either increased litter or stem density, and examined how much grain was removed nightly. We found that adding litter reduced the amount of grain removed in 2 of our 3 study areas. In the second experiment, we timed animals fleeing a simulated predator through various depths of litter or densities of stems. We found that dense stems impeded movement more than litter. In the third experiment, we recorded animals moving through native sagebrush steppe and cheatgrass monocultures, and analyzed these recordings to detect differences in the volume of noise created, especially for frequencies detected by common predators. We found that animals moving through cheatgrass made more noise at high frequencies, compared to native sagebrush steppe. Based on these experiments, cheatgrass monocultures may reduce habitat quality for small mammals by decreasing foraging efficiency and increasing vulnerability to predators. Mitigation strategies should focus on reducing the density of standing vegetation where predation is a limiting factor and litter depth where small mammals are food-limited.

Book excerpt: Biological invasions are driving environmental state changes on a global scale. Exotic plant species must be successful at passing several abiotic and biotic filters to establish and disrupt the native plant community assembly. Understanding where exotic plants are on a regional scale and being able to characterize how exotic plants are generally interacting with their environment is crucial information for exotic species management (chapter 1). In the western United States human-related activities are augmenting the spread of exotic plant species by increasing the ignitions of wildfire. Wildfire can lead to nutrient pulses through the removal of intact native communities and returning some mineral content into the soil. Exotic plant species that have traits that efficiently acquire nutrients accompanied by rapid growth rates may outcompete native plants. In chapters 2, 3, and 4 experimental fires demonstrated that the direct effect of fire may not be as critical as the potential indirect effects of fire such as altering the behavior of consumers (chapter 2) and reducing competition (chapters 3 and 4). In the Mojave desert, rodent consumers can have strong top-down effects on plant community assembly through foraging selection preferences. Life history traits such as seedling and seed size can lead to differential herbivory and positively benefit some plant species while inhibiting others (chapter 1) which could indirectly alter plant-plant interactions. Plant competition is a biotic filter than can determine establishment success or failure. Species that with rapid growth rates and plastic growth responses are likely to be able to capitalize on fluctuations in available resources. In the Great Basin, forecasts in climate change models predict that precipitation timing will lead to heavier fall rains and more rain than snow in the winter. Water availability is one of the main limiting factors in semi-arid and arid ecosystems where native plants have adaptive traits to maximize resource use. The interaction of wildfire and changes in climate, specifically timing of precipitation is critical to understand to be able to predict and protect against increasing wildfire frequency and severity. In chapter three, the responses by a key exotic annual grass, Bromus tectorum, and keystone native perennial shrub Artemisia tridentata subsp. wyomingensis, were positive for increased early fall precipitation but much more pronounced for B. tectorum. Exotic annual plants are able to respond to changes in timing of fall precipitation and have extreme growth which leads to superior competitive abilities through interference and priority effects (chapter 4). Native plants can compete with exotics but the magnitude of the effects are diminished compared to the negative interaction from exotics. Together these findings demonstrate that across several regions exotic annual grasses are capable of passing through abiotic filters and disrupting biotic interactions of the native plant community. This is likely to lead to increased spread of exotic annual species and may indicate potential and availability of fine fuel production supporting increases in size and frequency of wildfires in the western United States.
Book Synopsis Indirect Effects of Fire on the Small Mammal Community of a Tallgrass Blackland Prairie Remnant in Texas by : Brianna N. Kirchner

This book was released on 2009 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated effects of fire on vegetation and small mammals in a tallgrass blackland prairie remnant. At Leonhardt Prairie, vegetation and small mammals were monitored from February 2007 through May 2008 with a burn occurring Fall 2007. Pre-burn, dense litter and vegetative cover accommodated two dominant species, Baiomys taylori and Sigmodon hispidus, with a relative abundance (captures/100 trapnights) of 5.85 and 4.99, respectively. Post-burn, removal of vegetation led to an increase of Peromyscus maniculatus from a relative abundance of 0.12 pre-burn to 5.23 post-burn. Baiomys taylori and Sigmodon hispidus were not captured on burned sections for 7 months, though the unburned section maintained capture rates similar to pre-burn data. Shift in species composition has occurred from Baiomys taylori and Sigmodon hispidus to Peromyscus maniculatus, suggesting short-term fire response of small mammals in tallgrass prairies. This secondary successional cycle of 7 months suggests the prairie's natural fire frequency was high.

Book Synopsis Fire Behavior in Experimental Grass Fires by : Darko R. Veljkovic
Download or read book Fire Behavior in Experimental Grass Fires written by Darko R. Veljkovic and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasslands and other types of grass dominant ecosystems account for the majority of global fire events. Under climate change towards less humid and extended hot and dry periods, vulnerability of grass dominated ecosystems to a fire is projected to increase. Fire behavior is one of the key factors for understanding fire patterns and effects. This small-scale grass-fire experiment sought to explain how fire behavior properties of two bunchgrass species respond to increase in fuel density and composition. Although the results confirmed that higher fuel load and increased percentage of cheatgrass abundance leads to the increase in total mass consumption, rate of consumption and flame length, the relation with the decrease in the burning time is less defined. The burning properties of Idaho fescue were less influenced by increase in cheatgrass presence. These results highlight that changing fire behavior due to the increase in cheatgrass abundance is species specific and that more research is needed to understand the dynamics of both cheatgrass and other invasive species on fire behavior in grass dominated ecosystems.

Download or read book The Cascading Effects of Invasive Grasses in North American Deserts written by Tiffanny R. Sharp Bowman and published by . This book was released on 2015 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small mammals are primarily granivores; however, they also have strong impacts on the plant community via folivory. We tested for small mammal impacts on seedling survival in burned and unburned habitat. Small mammal access, burned vs. unburned habitat, and plant species were all important determinants of survival. Small mammals greatly reduced survival at both sites in burned and unburned habitat and often had a stronger impact in unburned than burned plots. Accounting for small mammal folivory may be a crucial step in successful post-fire rehabilitation.
