Evaluating Tree Height Using Pictometry® Hyperspatial Imagery, Daniel Unger, David Kulhavy, Matthew A. Wade

Faculty Publications

This study evaluated the use of Pictometry® hyperspatial 4-inch (10.2 centimeters) multispectral imagery to estimate height of baldcypress trees on the campus of Stephen F. Austin State University (SFASU), Nacogdoches, Texas. Actual tree heights of 60 baldcypress trees measured with a telescopic height pole were compared to Pictometry® estimated tree height. Linear correlation coefficients (r) and coefficient of determinations (R2) between actual tree height and Pictometry® estimated tree height for all 60 tress, and the shortest 30 and tallest 30 trees, were calculated. A paired t-test (alpha = 0.05) was calculated for all 60 tress, and the shortest 30 and …

A Remote Sensing And Gis-Based Wetland Analysis In Canaan Valley, West Virginia, Yisha Shi

Theses, Dissertations and Capstones

With the increasing influence in climate change and human activity, more and more people have begun to recognize the benefits of wetlands. However, there was a continuous annual net loss in the wetlands area since 1980s. Many programs have been implemented to monitor the status and trend of wetlands recently. In West Virginia, the wetlands area is a small portion of the State’s land, but it plays a key role in the whole ecosystem. This research aimed to detect the land cover and vegetation changes focusing on Canaan Valley area, which represents the greatest wetlands area of West Virginia. Remote …

Parallel Changes In Genital Morphology Delineate Cryptic Diversification Of Planktonic Nudibranchs, Alvin Alejandrino, Celia K. C. Churchill, Ángel Valdés, Diarmaid Ó. Foighil

Biology

The relative roles of geographical and non-geographical barriers in the genesis of genetic isolation are highly debated in evolutionary biology, yet knowing how speciation occurs is essential to our understanding of biodiversity. In the open ocean, differentiating between the two is particularly difficult, because of the high levels of gene flow found in pelagic communities. Here, we use molecular phylogenetics to test the hypothesis that geography is the primary isolating mechanism in a clade of pelagic nudibranchs, Glaucinae. Our results contradict allopatric expectations: the cosmopolitan Glaucus atlanticus is panmictic, whereas the Indo-Pacific Glaucus marginatus contains two pairs of cryptic species …

A Macrophysiological Analysis Of Energetic Constraints On Geographic Range Size In Mammals, Salvatore J. Agosta, Joseph Bernado, Gerardo Ceballos, Michael A. Steele

Biology Publications

Physiological processes are essential for understanding the distribution and abundance of organisms, and recently, with widespread attention to climate change, physiology has been ushered back to the forefront of ecological thinking. We present a macrophysiological analysis of the energetics of geographic range size using combined data on body size, basal metabolic rate (BMR), phylogeny and range properties for 574 species of mammals. We propose three mechanisms by which interspecific variation in BMR should relate positively to geographic range size: (i) Thermal Plasticity Hypothesis, (ii) Activity Levels/Dispersal Hypothesis, and (iii) Energy Constraint Hypothesis. Although each mechanism predicts a positive correlation between …

Wallace: The Review, And Wallace: The Preview, Charles H. Smith

DLPS Faculty Publications

In this essay commemorating the one hundred year anniversary of his death, Alfred Russel Wallace (1823–1913) is remembered for his main contributions to biogeography, and pointed to as a possible source of inspiration for future work in that field. As one of the science’s “fathers,” Wallace established both methods for study and a long-lived geographical systemization of animal distribution patterns. His efforts, moreover, may yet have the potential to inspire further new studies in the subject.

Using spatial analysis techniques, I …

A Further Look At The 1858 Wallace-Darwin Mail Delivery Question, Charles H. Smith

DLPS Faculty Publications

Recent investigations have led to a conclusion that Alfred Russel Wallace probably mailed his ‘Ternate’ paper on natural selection to Darwin a month later than some have thought, thus freeing Darwin from possible accusations of plagiarism. Further examination of the question suggests this conclusion is premature, as the evidence in favor of the later mailing date appears to be shakier than first thought.

Explaining China’S Wildlife Crisis: Cultural Tradition Or Politics Of Development, Peter J. Li

Threatened and Endangered Animal Populations Collection

This chapter is about China’s wildlife crisis. As the following sections attempt to demonstrate, abuse of and assault on wildlife in captivity and in the wild have reached an unprecedented level on the Chinese mainland in the reform era (1978–present). Shocking brutality against wildlife animals has been frequently exposed by Chinese and international media. To readers outside East Asia, they ask if the Chinese are culturally indifferent to animal suffering. Indeed, does the Chinese culture sanction cruelty to animals? Or is it the contemporary politics of economic development that is more directly responsible for the crisis?

Associations Of Housing, Management, Milking Activity, And Standing And Lying Behavior Of Dairy Cows Milked In Automatic Systems, Justine A. Deming, Renée Bergeron, Kenneth E. Leslie, Trevor J. Devries

Farm Animal Husbandry Collection

The objective of this cross-sectional study was to describe the housing, feeding management, and characteristics (parity and stage of lactation) of cows on commercial automatic milking system (AMS) dairies and their associations with the standing and lying behavior patterns and milking activity (frequency and yield) of lactating dairy cows. Thirteen AMS herds were enrolled in the study, with an average herd size of 71 ± 30 (mean ± SD; range: 34 to 131) lactating cows. All of the herds used freestall barns, each set up for free cow traffic to the AMS. On-farm measurements were taken to determine stocking density …

Interpretation Of Gypsy Moth Frontal Advance Using Meteorology In A Conditional Algorithm, K. L. Frank, P. C. Tobin, H. W. Thistle Jr., Laurence S. Kalkstein

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The gypsy moth, Lymantria dispar, is a nonnative species that continues to invade areas in North America. It spreads generally through stratified dispersal where local growth and diffusive spread are coupled with long-distance jumps ahead of the leading edge. Longdistance jumps due to anthropogenic movement of life stages is a well-documented spread mechanism. Another mechanism is the atmospheric transport of early instars and adult males, believed to occur over short distances. However, empirical gypsy moth population data continue to support the possibility of alternative methods of longrange dispersal. Such dispersal events seemed to have occurred in the mid- to …

Genetic Testing For Tmem154 Mutations Associated With Lentivirus Susceptibility In Sheep, Michael P. Heaton, Theodore S. Kalbfleisch, Dustin T. Petrik, Barry Simpson, James W. Kijas, Michael L. Clawson, Carol G. Chitko-Mckown, Gregory P. Harhay, Kreg A. Leymaster, International Sheep Genomics Consortium

Roman L. Hruska U.S. Meat Animal Research Center: Reports

In sheep, small ruminant lentiviruses cause an incurable, progressive, lymphoproliferative disease that affects millions of animals worldwide. Known as ovine progressive pneumonia virus (OPPV) in the U.S., and Visna/Maedi virus (VMV) elsewhere, these viruses reduce an animal’s health, productivity, and lifespan. Genetic variation in the ovine transmembrane protein 154 gene (TMEM154) has been previously associated with OPPV infection in U.S. sheep. Sheep with the ancestral TMEM154 haplotype encoding glutamate (E) at position 35, and either form of an N70I variant, were highly-susceptible compared to sheep homozygous for the K35 missense mutation. Our current overall aim was to characterize TMEM154 in …

An Investigation Of The Differences Between Real Time Mesoscale Analysis And Observed Meteorological Conditions At Raws Stations In The Northeast United States, Joseph J. Charney, Shiyuan Zhong, Michael T. Kiefer, Xiaoqing Zhu, Greg Soter, Adam Cinderich

Joint Fire Science Program Research Project Reports

This project investigates the differences between the gridded meteorological fields produced by the Real Time Mesoscale Analysis (RTMA) and observed meteorological conditions at Remote Automated Weather Stations (RAWS) for two years in the northeastern United States. National Weather Service (NWS) fire weather forecasts are produced using the National Digital Forecast Database (NDFD), which is a gridded analysis of meteorological fields generated by forecasters at NWS forecast offices nationwide. The NDFD is verified by comparing its gridded meteorological fields against the RTMA, which is an advanced modeling and data assimilation system that provides the best-available hourly gridded estimate of surface and …

Development Of Modeling Tools For Predicting Smoke Dispersion From Low-Intensity Fires, Warren E. Heilman, Shiyuan Zhong, John L. Hom Dr., Joseph J. Charney

Joint Fire Science Program Research Project Reports

Of particular concern to fire and air-quality management communities throughout the U.S. are the behavior and air-quality impacts of low-intensity prescribed fires for fuels management. For example, smoke from prescribed fires, which often occur in wildland-urban interface (WUI) areas and in areas where forest vegetation has a significant impact on the local meteorology, can linger for relatively long periods of time and have an adverse effect on human health. Smoke from wildland fires can also reduce visibility over roads and highways in the vicinity of and downwind of these fires, reducing the safety of our transportation system. The planning for …

The Economic Effects Of Large Wildfires, Cassandra Mosley Dr., Krista Gebert, Pamela Jakes Dr., Laura Leete Dr., Max Nielsen-Pincus Dr., Emily Jane Davis Dr., Autumn Ellison, Cody Evers, Branden Rishel, Shiloh Sundstrom

Joint Fire Science Program Research Project Reports

Large wildfires disrupt the lives of workers, families, and employers. However, fire suppression and recovery efforts may provide economic opportunities. Unlike with other natural hazards, there has been little research about how wildfires affect local economies. The purpose of this project was to analyze the effects of large wildfires on labor markets and examine how fire suppression spending may mediate these effects. Main findings from this research suggest that (1) in the short term, labor market impacts from large wildfires are positive during the course of a fire, (2) in the long-­‐term, large wildfires lead to greater economic instability by …

Human impacts have seriously damaged mangroves, and conservation of mangroves will require information on local and regional population genetic structures. Here, we report the development and polymorphism of eleven novel microsatellite markers, developed using next- generation sequencing on 56 samples of widespread man- grove species Xylocarpus granatum (Meliaceae) from nine populations across the Indo-West Pacific region. All loci were found to be polymorphic, with the number of alleles per locus ranging from four to 19. In a population from Sabah (Malaysia), the mean observed and expected heterozygosity per locus was 0.59 and 0.58, respectively. No null allele, significant linkage disequilibrium …

Horses were domesticated from the Eurasian steppes 5,000–6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F_ST calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely …

Five Year Carbon Storage Analysis In The Gordon Natural Area, Joy Fritschle, Chad Hudson, Catherine Spahr, Andy Tamez

Forest Carbon Storage Study Documents

The Gordon Natural Area (GNA) serves as a natural laboratory for a range of class research projects. In a Geography Field Methods course led by Dr. Fritschle, students established five permanent carbon-study plots in 2008. Since then, students have returned to these plots to measure the carbon stock of standing trees in five plots located along a topographic gradient: floodplain, ridge-top, lower mid-slope, mid-slope and upper mid-slope. Using U.S. Forest Service established guidelines, all trees greater than 5 cm and up to 73 cm in diameter at breast height (DBH) were measured and identified within each 40 m circular plot. …

The Mid-Domain Effect: It’S Not Just About Space, Andrew D. Letten, S. Kathleen Lyons, Angela T. Moles

School of Biological Sciences: Faculty Publications

Ecologists and biogeographers have long sought to understand how and why diversity varies across space. Up until the late 20th century, the dominant role of environmental gradients and historical processes in driving geographical species richness patterns went largely undisputed. However, almost 20 years ago, Colwell & Hurtt (1994) proposed a radical reappraisal of ecological gradient theory that called into question decades of empirical and theoretical research. That controversial idea was later termed the ‘the mid-domain effect’: the simple proposition that in the absence of environmental gradients, the random placement of species ranges within a bounded domain will give rise to …

Different Modes Of Evolution In Males And Females Generate Dichromatism In Fairy-Wrens (Maluridae), Allison E. Johnson, J. Jordan Price, Stephen Pruett-Jones

School of Biological Sciences: Faculty Publications

Sexual dichromatism in birds is often attributed to selection for elaboration in males. However, evolutionary changes in either sex can result in plumage differences between them, and such changes can result in either gains or losses of dimorphism. We reconstructed the evolution of plumage colors in both males and females of species in Maluridae, a family comprising the fairy-wrens (Malurus, Clytomias, Sipodotus), emu-wrens (Stipiturus), and grasswrens (Amytornis). Our results show that, across species, males and females differ in their patterns of color evolution. Male plumage has diverged at relatively steady rates, whereas …

Large-Scale Spatial Synchrony And Cross-Synchrony In Acorn Production By Two California Oaks, Walter D. Koenig, Johannes M.H. Knops

School of Biological Sciences: Faculty Publications

Seed production that varies greatly from year to year, known as ‘‘masting’’ or ‘‘mast-fruiting’’ behavior, is a population-level phenomenon known to exhibit geographic synchrony extending, at least in some cases, hundreds of kilometers. The two main nonexclusive hypotheses for the driver of such geographically extensive synchrony are (1) environmental factors (the Moran effect), and (2) the mutual dependence of trees on outcrossed pollen (pollen coupling). We tested 10 predictions relevant to these two hypotheses using 18 years of acorn production data on two species of California oaks. Data were obtained across the entire ranges of the two species at 12 …
