Recent Regulation Changes Regarding Invasive Species In Mexico And The Development Of Mexico’S National Strategy On Invasive Species, Francisco Abarca Jan 2010

Recent Regulation Changes Regarding Invasive Species In Mexico And The Development Of Mexico’S National Strategy On Invasive Species, Francisco Abarca

National Invasive Species Council

Between November 2008 and February 2010, Mexico made several modifications to existing environmental and wildlife regulations regarding invasive species.

On November 2008, the Deputy Chamber made several modifications to the Ecological Equilibrium and Environmental Protection General Law (LGEEPA by its Spanish acronym; equivalent to NEPA), and the Wildlife General Law. These modifications were published in the Federal Register until February 2010.

The intent of these modifications was to strengthen existing regulations by incorporating more specific language dealing with invasive species and make these regulations more in tune with other regulations outside of the wildlife arena, such as the Forestry, …

Chemistry Faculty Publications and Presentations

During the 2006 Texas Air Quality Study and Gulf of Mexico Atmospheric Composition and Climate Study (TexAQS-GoMACCS 2006), the optical, chemical and microphysical properties of atmospheric aerosols were measured on multiple mobile platforms and at ground based stations. In situ measurements of the aerosol light extinction coefficient (σep) were performed by two multi-wavelength cavity ring-down (CRD) instruments, one located on board the NOAA R/V Ronald H. Brown (RHB) and the other located at the University of Houston, Moody Tower (UHMT). An AERONET sunphotometer was also located at the UHMT to measure the columnar aerosol optical depth (AOD). The σep data …


Identifying Potential Carbon Flux Responses To Shifting Hydroecological And Climactic Regimes In The Peace-Athabasca Delta, Caleb W. Light Jan 2010

Identifying Potential Carbon Flux Responses To Shifting Hydroecological And Climactic Regimes In The Peace-Athabasca Delta, Caleb W. Light

Theses and Dissertations (Comprehensive)

The CO2 flux response of organic carbon stored in lake sediments and littoral peat contained in sensitive, northern wetlands may contribute to accelerating atmospheric CO2 concentrations. Temperature and moisture conditions are important variables that affect the rate and quantity of CO2 released to the atmosphere from organic matter stored in lake sediments and peat. Antecedent hydroecological conditions also influence the direction and magnitude of CO2 fluxes to the atmosphere in a changing environment. To better understand and characterize the role of antecedent conditions on CO2 fluxes, this study combines paleolimnological reconstructions with laboratory incubations of littoral peat and lake sediment …


Characterization Of Secondary Organic Aerosol (Soa) Formed By The Reaction Of Β-Caryophyllene, Soot And Ozone: Climate Impact, A. Sarkar, N. A. Marley, J. S. Gaffney Jan 2010

Characterization Of Secondary Organic Aerosol (Soa) Formed By The Reaction Of Β-Caryophyllene, Soot And Ozone: Climate Impact, A. Sarkar, N. A. Marley, J. S. Gaffney

Journal of the Arkansas Academy of Science

Diesel soot (black carbon, BC) is an important light absorbing aerosol component in atmosphere that can cause tropospheric heating. Laboratory studies have found it to be unreactive to ozone at ambient temperature. The low uptake coefficient i.e., γ 300 K = 2× 10-7 , of the soot-O3 reaction indicates a low probability of irreversible O3 loss from gas phase to surface-adsorbed product (Particle phase). This shows clearly that at low temperature soot is not reactive with atmospheric oxidants. In contrast, sesquiterpenes (SQT) such as β-caryophyllene (C15H24), which are produced primarily by plants, are extremely reactive with ozone. For example, the …


Physiological And Biochemical Attributes Of Red-Fleshed Dragon Fruit, Hylocereus Polyrhizus., Punitha R. Vasanthan Jan 2010

Physiological And Biochemical Attributes Of Red-Fleshed Dragon Fruit, Hylocereus Polyrhizus., Punitha R. Vasanthan

Student Works (2010-2019)

An understanding of the postharvest parameters is essential for the successful market introduction of red-fleshed dragon fruit, Hylocereus polyrhizus, which has been recently developed as fruit crop. In this study, fruit at three different harvest maturities were evaluated in terms of physiological and biochemical aspects. Fruit which were harvested at complete red stage maintained their quality for up to one week. On the other hand, fruit harvested at early maturity attained the physical properties of fruit ripened on the plant (firmness reduced, peel colour changes, pH increased) but they contained noticeably lower concentrations of soluble sugars suggesting that fruit can …

National Drought Mitigation Center: Faculty Publications

Increasing surface temperatures and climatic variability associated with global climate change are expected to produce more frequent and intense heat waves and droughts in many parts of the world. Our goal was to elucidate the fundamental, but poorly understood, effects of these extreme weather events on avian communities across the conterminous United States. Specifically, we explored: (1) the effects of timing and duration of heat and drought events, (2) the effects of jointly occurring drought and heat waves relative to these events occurring in isolation, and (3) how effects vary among functional groups related to nest location and migratory habit, …

Native Species Interactions With Red Brome: Suggestions For Burn-Area Revegetation, Scott R. Abella Jan 2010

Native Species Interactions With Red Brome: Suggestions For Burn-Area Revegetation, Scott R. Abella

Public Policy and Leadership Faculty Research

In deserts, native perennial plants often actually facilitate the establishment of exotic annual grasses. One of our focal areas of research is to identify native species for use in revegetation projects that reduce the establishment of exotic annual grasses, or at least do not strongly facilitate exotic species establishment. An initial research effort involving a competition experiment of red brome with native species and a correlational field study of brome distribution among native perennial plants is in press with the journal Invasive Plant Science and Management.

Trying To Beat The Brome: Understanding Establishment Thresholds And Choosing Competitive Native Species At Parashant National Monument, Scott R. Abella, E. Cayenne Engel

Public Policy and Leadership Faculty Research

Desert fires fueled by exotic grasses like the omnipresent red brome (Bromus rubens) can be intense and cause widespread mortality of native vegetation. Native desert scrub communities such as those dominated by blackbrush (Coleogyne ramosissima) do not readily reestablish after fire (Abella 2009) and may even become more abundant in the post-burn landscape initiating a fire cycle that occurs at a greater frequency than the recovery time of the long-lived desert perennial community.

Biological Sciences Faculty Publications

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the …

Development Of The Mask Scentometer, A Comparison Of Ambient Odor Assessment Methods, And Their Application In Ground Truthing Atmospheric Dispersion Models, Christopher G. Henry

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

This dissertation is organized as four stand-alone papers. Paper No. 1 describes the development of the Mask Scentometer and reports dilution ratios measured during use by twelve different people. Dilution ratios at the Mask Scentometer’s five dilution-to-threshold (D/T) settings were found to be 0.35, 1, 2, 4.5 and 18. In Paper No.’s 2 and 4, ambient odor assessment methods were compared in both controlled laboratory conditions and in the field. Laboratory analysis of ambient air samples using dynamic triangular forced-choice olfactometry (DTFCO) did not correlate well with any of the ambient odor assessment methods. Average intensity-predicted D/T was roughly five …

Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer Dec 2009

Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer

Earth and Soil Sciences

Human induced disruption of the environment is prevalent in every culture. In Brazil, the effects of massive deforestation have become apparent since the nineteen eighties. However, along with deforestation, and a coinciding loss in an economic resource for the country, is a significant loss of natural habitat and species extinction. The Amazon in Brazil contains a large proportion of the world’s species diversity that is threatened by the socio-economic activities of modern Brazilian culture. Historically and presently, indigenous groups have contributed to insignificant levels of ecological disruption and are themselves threatened by the activities of modern Brazilians. The effects of …

Provenance Signatures Of The Antarctic Ice Sheets In The Ross Embayment During The Late Miocene To Early Pliocene: The Andrill And-1b Core Record, Franco M. Talarico, Sonia Sandroni Nov 2009

Provenance Signatures Of The Antarctic Ice Sheets In The Ross Embayment During The Late Miocene To Early Pliocene: The Andrill And-1b Core Record, Franco M. Talarico, Sonia Sandroni

ANDRILL Research and Publications

Significant down-core modal and compositional variations are described for granule- to cobble-sized clasts in the Early Pliocene to Middle/Late Miocene sedimentary cycles of the AND-1B drill core at the NW edge of the Ross Ice Shelf (McMurdo Sound).

Long-term shifts in compositional patterns outline an evolving provenance which is interpreted as reflecting the combined effects and complex interactions among variations in ice volume, ice flow patterns and paleogeographic changes linked to the local tectonic and volcanic activity. High-frequency variations and the petrological features of the basement clast fraction provide direct information about the potential source regions during both glacial maxima …
