Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez

Cal Poly Humboldt theses and projects

The conservation and recovery of anadromous salmonids (Oncorhynchus sp.) depend on stream restoration and protection of freshwater habitats. In-stream large wood dictates channel morphology, increases retention of terrestrial inputs such as organic matter, nutrients and sediment, and enhances the quality of fish habitat. Historic land use/land cover changes have resulted in aquatic systems devoid of large wood. Restoration by placement of large wood jams is intended to restore physical and biological processes. An important question for scientists and restoration managers, in addition to the initial effectiveness of restoration, is the persistence and fate of large wood installations. In this …

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

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 beyond the …

Ecological And Organic Life Safety Concerns Of Hfo-1234yf, Alberni V. Ruiz

STAR Program Research Presentations

While at NOAA my research was directed by the inquiry of whether or not HFO-1234yf, a new compound being introduced into coolant system and replacing greenhouse gases HFC, is harmful to organic life. Using the computer program Matlab I was able to develop figures that represented the concentration of HFO-1234yf (HFO) in 12 different tower locations throughout the country. Comparing and contrasting concentrations of this HFO compound at each site led me to the question the possible harmful side effects this compound could bring to organic life due to the fact that concentration levels are increasing, with one factor being …

The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry

DePaul Discoveries

Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however, …

Herpetoplogical Survey Across Three Distinct Habitats In Ankarana National Park: Long-Term Effects Of Past Land Use On Species Composition In And Around The Park, Julia Park

Independent Study Project (ISP) Collection

Ankarana National Park is home to a diverse population of herpetofauna. In this study, three distinct habitats in and around Ankarana National Park were surveyed for herpetological diversity. These habitats were defined as the deciduous forest located within the “tsingy” limestone karst canyons, the dry deciduous forest outside of the canyons, within the borders of the park, and the anthropogenically affected forest outside of the park’s borders, which is subject to logging and fruit tree harvesting. A total of 27 species of herpetofauna – six amphibian and 21 reptile species were found over the course of twelve days of surveying …

The Effects Of Disturbance And Species Specific Interactions On Diversity In An Agent Based Forest Simulation, Matthew E. Mills

Theses and Dissertations

In ecology literature, there is much data which suggests that conspecific negative density dependence (CNDD) and abiotic disturbances increase biodiversity in forests. This thesis elucidates the notion that not only do these two forces increase diversity, but they may also interact with one another in order to achieve higher levels of biodiversity. Abiotic disturbances, like fires and hurricanes, can indirectly impact conspecific effects because when these forces remove individuals from the landscape, the role of the conspecific effects will change. The interaction of these two factors in biodiversity are explored in an agent based forest simulation through a resource surface. …

Breeding Season Avian Community Composition And Prey Availability In Eucalyptus And Slash Pine Plantations Of Southwestern Louisiana, Elizabeth J. Messick

Electronic Theses and Dissertations

The increased demand for wood products related to industries such as bioenergy and paper has resulted in a need for a consistent supply of raw materials. Eucalyptus (Eucalyptus spp.) plantations have the potential to boost wood production for pulpwood and biomass feedstocks. Species characteristics such as rapid, indeterminate growth, coppice regrowth, resistance to disease and insects, and tolerance of a range of environmental conditions make these species successful short-rotation woody crops (SRWCs). Camden white gum (Eucalyptus benthamii), a more cold tolerant species, has made management of eucalyptus plantations viable in southern portions of the United States such …

Changes In Floristic Composition In The State Forests In Worcester County (Massachusetts) Over 34 Years, Flor A. Monroe

Sustainability and Social Justice

ABSTRACT

CHANGES IN FOREST DIVERSITY OF STATE FOREST IN WORCESTER COUNTY, MASSACHUSETTS, OVER 34 YEARS PERIOD

The forest in Massachusetts has changed since the earliest colonial settlement and today the floristic composition is more homogeneous. This study investigates the potential change in the floristic composition over thirty years in Worcester County State Forests. Shannon, richness and evenness indices for two periods were compared, and Jaccard index was used to analyze similarity in composition between the periods. The possible influence of severe weather events was also analyzed.

It was found Changes in the floristic composition, but the magnitude of the changes …

An Illustrated Id Guide To The Crayfishes Found In Nebraska Native And Non-Native, Steve Schainost

Nebraska Invasive Species Program

There are five crayfishes native to Nebraska. These are:

Orconectes immunis (papershell crayfish)

Orconectes virilis (northern crayfish)

Orconectes neglectus neglectus (ringed crayfish)

Cambarus diogenes (Devil crayfish)

Procambarus gracilis (prairie crayfish)

Three additional non-native crayfishes have also been found here:

Orconectes rusticus (rusty crayfish) [bait tanks and established in two ponds in Omaha]

Procambarus clarkii (red swamp crayfish) [bait tanks]

Procambarus acutus (White River crayfish) [bait tanks]

I will attempt here to provide a photographic guide to field identification, one species per page.

Rex ' 96 : An Expert Guide To Revegetation, David Bicknell

Journal of the Department of Agriculture, Western Australia, Series 4

Agriculture Western Australia has provided coordination and technical input to a powerful source of information on plants for Australian conditions. David Bicknell outlines some of its features and uses.

Farmers, local government, advisers and even gardeners often have trouble finding the right plant for the right place for a given purpose. Rather than spend a lot of time, money and effort looking through scattered sources of information, many people stick with a limited number of species year after year. This neglects plants that may be much better suited to the purpose, and also fails to develop Australia's huge range of …

Protecting The Remnants, Glenis Ayling

Journal of the Department of Agriculture, Western Australia, Series 4

Our native flora and fauna do best in their own environment, so one way of protecting them is to conserve and maintain areas of remnant vegetation throughout our farmlands. This is the aim of the Remnant Vegetation Protection Scheme in which the State Government helps private landholders to voluntarily fence off and manage areas of native vegetation on farms.
