Importance Of Scale, Land Cover, And Weather On The Abundance Of Bird Species In A Managed Forest, Alexis R. Grinde, Gerald J. Niemi, Brian R. Sturtevant, Hannah Panci, Wayne Thogmartin, Peter Wolter 2017 University of Minnesota - Duluth

Importance Of Scale, Land Cover, And Weather On The Abundance Of Bird Species In A Managed Forest, Alexis R. Grinde, Gerald J. Niemi, Brian R. Sturtevant, Hannah Panci, Wayne Thogmartin, Peter Wolter

Natural Resource Ecology and Management Publications

Climate change and habitat loss are projected to be the two greatest drivers of biodiversity loss over the coming century. While public lands have the potential to increase regional resilience of bird populations to these threats, long-term data are necessary to document species responses to changes in climate and habitat to better understand population vulnerabilities. We used generalized linear mixed models to determine the importance of stand-level characteristics, multi-scale land cover, and annual weather factors to the abundance of 61 bird species over a 20-year time frame in Chippewa National Forest, Minnesota, USA. Of the 61 species modeled, we were ...

Riparian buffers are a promising tool in efforts to reduce sediment contribution to streams. Models that predict the capacity of buffers to trap sediment have recently been developed. A number of parameters that are required to conduct such modeling efforts are derived from the topography of the site. In this study, three topographic data sources were used to generate the model input for an agricultural field with a riparian buffer. The runoff and sediment transport in the system was then simulated for three years. As a result, the area that contributed runoff and sediment to the buffer was substantially different ...

The elevational gradient in plant defense (EGPD) hypothesis posits that natural enemy pressures increase alongside temperature across elevational climatic gradients, thereby selecting for enhanced defenses at lower elevations while leaving plants less defended at higher elevations. Phylogenetically constrained tests of this hypothesis are uncommon, with tests focused on defenses of mature trees in natural settings being exceedingly rare. In the absence of this information, predicting the spatiotemporal dynamics of forest pests that preferentially attack mature trees is rendered more difficult. Tree properties such as age, growth rate, and size have all been correlated with levels of tree defenses against insect ...

Establishing Pine Monocultures And Mixed Pine-Hardwood Stands On Reclaimed Surface Mined Land In Eastern Kentucky: Implications For Forest Resilience In A Changing Climate, Geoffrey Bell, Kenton L. Sena, Christopher D. Barton, Michael French

Forestry and Natural Resources Faculty Publications

Surface mining and mine reclamation practices have caused significant forest loss and forest fragmentation in Appalachia. Shortleaf pine (Pinus echinata) is threatened by a variety of stresses, including diseases, pests, poor management, altered fire regimes, and climate change, and the species is the subject of a widescale restoration effort. Surface mines may present opportunity for shortleaf pine restoration; however, the survival and growth of shortleaf pine on these harsh sites has not been critically evaluated. This paper presents first-year survival and growth of native shortleaf pine planted on a reclaimed surface mine, compared to non-native loblolly pine (Pinus taeda), which ...

Forest understory fuels can have profound effects on fire behavior and crown fire initiation. Accurate fire behavior prediction in understory fuels is an essential component for estimating fire intensity and severity during wildfire and prescribed fire events. This study focused on estimating temporal and seasonal changes in fuel loading parameters associated with the expansion of invasive yaupon (Ilex vomitoria), Chinese privet (Ligustrum sinense), and Chinese tallow (Triadica sebifera) in East Texas pine and hardwood ecosystems. Fuel loading data of invasive species infested sites indicated significant increases in understory biomass when compared to 1988 estimates, suggesting a clear need to revise ...

Initial Development Of Surface Fuel Models For The Netherlands, Brian P. Oswald, Nienke Brouwer, Ester Willemsen

Faculty Publications

Estimating the spread of wildland fire is growing concern in the Netherlands, where fire events at the wildland urban interface is a growing concern with a changing climate. A multi-year project was initiated in 2012 to obtain field-based fuel measurements to be used to estimate wildland fire spread for surface fire. The overall objective was to develop either custom fuel models or utilize existing Northern American fuel models to fuel conditions in some of the hazardous vegetation in the Netherlands. Over a four-year period, 96 plots were established, a wide variety of fuel parameters measured, and ANOVA (p ≤ 0.1 ...

Effects Of Salinity And Wet–Dry Treatments On C And N Dynamics In Coastal-Forested Wetland Soils: Implications Of Sea Level Rise, Xijun Liu, Alexander Ruecker, Bo Song, William H. Conner, Alex T. Chow

Publications

Forested wetlands dominated by baldcypress (Taxodium distichum) and water tupelo (Nyssa aquatica) are commonly found in coastal regions of the southeastern United States. Global climate change and in particular sea level rise will alter the frequency and magnitude of wet/dry periods and salinity levels in these ecosystems. Soil microcosm experiments were set up to identify the effects of water level variations (0.4–3.0 g-water g-soil−1) and salinity changes (0, 1 and 5 ppt of NaCl) on greenhouse gas emissions (CH4, CO2, and N2O) and dissolved organic carbon (DOC) characteristics from forested wetland soils. Our results indicate ...

Landowners' Willingness To Supply Woody Biomass For Biofuel In West Alabama, Gilbert Adjoyi, Ellene Kebede 2017 Tuskegee University

Landowners' Willingness To Supply Woody Biomass For Biofuel In West Alabama, Gilbert Adjoyi, Ellene Kebede

Professional Agricultural Workers Journal

Abstract

The Concern for national energy security, rural development, and climate change has created a wider attention for biofuels from woody biomass in recent times. For instance, West Alabama is an area of interest for stakeholders regarding the production of woody biomass. Therefore, the main objective of this study was to examine landowners’ willingness to supply woody biomass for biofuel in West Alabama. A mail survey of randomly selected landowners was conducted in eight selected counties. The results indicated that the average forestland owner is male, between ages of 40 and 57, with an average of 27 years of land ...


Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro 2017 The Graduate Center, City University of New York

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space ...

Reconstruction Of Piñon-Juniper Forest Structure To Examine Historic Wildlife Habitat Characteristics In The Davis Mountains, Usa, Brian P. Oswald, John R. Lanham, James C. Kroll, Mohammed M. Bataineh, Yanli Zhang

Faculty Publications

Changes in piñon-juniper (Pinus spp., Juniperus spp.) communities across the southwestern United States have often decreased ecological diversity of the understory and increases of exotic species. Reconstructing age and establishment patterns provides essential understanding to guide treatments and management for anthropogenically-altered forests. The goal of this study was to determine how patterns of piñon and juniper growth in the Davis Mountains, Texas, varied over time and how this pattern influenced wildlife habitat of several indicator species. Establishment patterns and basal area growth progression were identified, canopy cover estimates regressed from pre-developed canopy regression equations to re-construct historic forest stand structure ...


Evaluating The Influence Of Stem Form And Vigor On Product Potential, Growth, And Survival For Northern Commercial Hardwood Species, Mark Castle 2017 The University of Maine

Evaluating The Influence Of Stem Form And Vigor On Product Potential, Growth, And Survival For Northern Commercial Hardwood Species, Mark Castle

Electronic Theses and Dissertations

Northern hardwood and mixed-wood forest types occupy a considerable percentage of the forest landscape across the Northeastern United States and portions of eastern Canada. While capable of producing valuable saw timber and veneer products, hardwood species demonstrate a wide range of stem quality resulting from the large variety of stem forms and defects that these species can manifest. The effect of different stem forms and damage has largely not been accounted for in predictions of volume, growth, and mortality. In addition to potential bias in growth and yield applications, the lack of quantification of these features has left the efficacy ...


Irrigation For Vegetable Crops In Iowa, A. T. Erwin, E. S. Haber 2017 Iowa State College

Irrigation For Vegetable Crops In Iowa, A. T. Erwin, E. S. Haber

Bulletin

Does it pay to irrigate vegetable crops in Iowa?

What does it cost to irrigate? and under what conditions are these costs, plus a profit, returned to the vegetable grower?

No complete answer to these questions can be given, because of the widely varying conditions involved—differences of rainfall, of crops, of costs, of soil, of topography. But considerable light is thrown on them by experiments which the Vegetable Crops Subsection of the Iowa Agricultural Experiment Station has conducted during several years at Ames and on “Muscatine Island.’’


The Peppers, A. T. Erwin 2017 Iowa State College

The Peppers, A. T. Erwin

Bulletin

Peppers are native plants of tropical America, one of the few vegetables which still abound in the wild state. The earliest mention of them was in a report of Columbus’ first voyage.

The garden peppers are regarded as dwarf, early maturing forms of Capsicum frutescens. They are either annuals or perennials, according to climatic conditions.

The peppers are both self and cross-fertilized.

The collection of peppers grown in securing the data for this bulletin, included over 200 varieties, a large proportion of which were synonyms, secured from the American and European seed trade.


The Effect Of Various Containers On The Growth Of Vegetable Plants, E. S. Haber 2017 Iowa State College

The Effect Of Various Containers On The Growth Of Vegetable Plants, E. S. Haber

Bulletin

The experiments indicate that clay pots are superior, as a general rule, to composition pots, paper bands or flats as a growing medium for vegetable plants. If the plants in these substitute containers, however, are watered, about every week or 10 days with a solution of nitrate of soda, sulfate of ammonia or any other nitrogenous fertilizer at the rate of 1 ounce to 1 gallon of water, plants equal to those produced in clay pots are possible. A few species may do as well without nitrates; cabbage plants grown in peat pots were slightly better than those in clay ...
