Methods are needed to predict the spatial distribution pattern(s) of forest harvests to improve large-scale timber inventories through the incorporation of spatial distribution information. In this study, land cover type change detection methods were carried out using information from 1972 thru 2005 east-central Mississippi Landsat TM data to detect the spatial distribution of clearcut forest harvests. A random pattern was observed for clearcut harvests and this and other statistical data gathered in the study will be integrated into an existing forest inventory and transportation network database. The resulting harvested and forested area predictions generated by the database will assist with determining the sustainability and availability of forest resources for existing and future forest product mills and the creation of transportation networks needed to supply raw materials and distribute end products. Other implications include assessment of the quality and spatial components of wildlife habitat and a tool for forest certification programs.

Spotted Salamanders, Ambystoma maculatum, are a widely distributed pond-breeding amphibian that spends an estimated 95% of its life in woodlands surrounding breeding ponds. Their terrestrial ecology remains poorly understood. Few studies have tracked the movement patterns of Spotted Salamanders, and they have given limited information on fine scale patterns. Studies of distribution around vernal pool environments have brought increased attention to their terrestrial ecology. To this end I tracked a sample of Passive Integrated Transponder (PIT) tagged animals with a Radio Frequency Identification Device (RFID). Quadrat-variance methods and a Poisson distribution were used to analyze spatial distribution patterns over 2 years. The home range size of 10 Spotted Salamanders was calculated using the revised minimum area method. A clumped distribution was found at larger spatial scales, except in the first year of the study. Home range size was shown to be limited and highly variable among 10 individuals (Mean=4.29m2, Standard Deviation=6.25).

The human cell is complex, with countless processes ongoing in parallel in specialized compartments, the organelles. Cells can be studied in vitro by using immortalized cell lines that represent cells in vivo to a varying degree. Gene expression varies between cell types and an average cell line expresses around 10,000-12,000 genes, as measured with RNA sequencing. These genes encode the cell’s proteome; the full set of proteins that perform functions in the cell. In paper I we show that RNA sequencing is a necessary tool for studying the proteome of the human cell. By studying the proteome, and proteins’ localization in the cell, information can be assembled on how the cell functions. Image-based methods allow for detailed spatial resolution of protein localization as well as enable the study of temporal events. Visualization of a protein can be accomplished by using either a cell line that is transfected to express the protein with a fluorescent tag, or by targeting the protein with an affinity reagent such as an antibody. In paper II we present subcellular data for a majority of the human proteins, showing that there is a high degree of complexity in regard to where proteins localize in the cell. Cellular energy is generated in the mitochondria, an important organelle that is also active in many other different functions. Today approximately only a third of the estimated mitochondrial proteome has been validated experimentally, indicating that there is much more to understand with regard to the functions of the mitochondria. In paper III we explore the mitochondrial proteome, based on the results of paper II. We also present a method for sublocalizing proteins to subcompartments that can be performed in a high-throughput manner. To conclude, this thesis shows that transcriptomics is a useful tool for proteome-wide subcellular localization, and presents high-resolution spatial distribution data for the human cell with a deeper analysis of the mitochondrial proteome. / <p>QC 20170512</p>

Comets are important for solar system studies because their interiors hold evidence of the conditions in which they formed in the outer solar system. However, the coma obscures the nucleus from view when observations are most easily performed, thus it is important to understand the nature of cometary comae. This study examines the spatial distribution of CN radicals in the coma of comet Encke and determines the likelihood that CN is a photodissociative daughter of HCN in the coma. Observations of CN were obtained from October 22-24, 2003, using the 2.7 m Cassegrain telescope at McDonald Observatory in Fort Davis, TX. The classical vectorial model was modified by introducing a fan-like feature in order to explain Encke’s aspherical coma. The results are consistent with HCN being the photodissociative parent of CN, based on the OH/CN ratios and the physical parameters used to match the model profiles with the observations.

The Mesolithic period in Sweden lasted generally between 9500-4000 BC and is characterised by the dynamic landscape. People usually lived in smaller groups by the coast, sustained by the forests and the sea’s resources. The study is limited to central Sweden, specifically the province of Västmanland. Fourteen settlements are analysed through an archaeological analysis with an ecological perspective in order to answer how the Mesolithic people utilised the landscape resources and how this is reflected in said landscape. In conclusion, people used the landscape in order to accommodate their current needs long term or short term.

Grande parte desta região está protegida no Parque Estadual do Morro do Diabo (PEMD), considerada insuficientemente conhecida, mas de provável importância biológica em relação a herpetofauna. O presente estudo objetivou-se por estudar os padrões de distribuição espacial e temporal da anurofauna do PEMD, e também verificar como a heterogeneidade dos corpos d’água influencia na composição e riqueza de espécies de anfíbios. De maneira geral, as espécies de anfíbios registradas no PEMD (tanto adultos em atividade de vocalização quanto girinos) ocorreram diferentemente entre os variados tipos de corpos d’água amostrados, sendo principalmente relacionado com tipo de correnteza e hidroperíodo dos corpos d’água. Assim, a composição da anurofauna foi diferente entre corpos d’água lóticos, lênticos permanentes/semi-permanentes e lênticos temporários. A ocorrência temporal das espécies foi restrita aos meses quente e úmido do ano (com exceção de uma espécie que ocorreu durante os meses frio e seco), o que resultou em alta sobreposição temporal no período de vocalização dos machos e ocorrência de girinos. Grupos de espécies ocorreram diferentemente ao longo dos meses quente e úmido, com espécies características de início, meio e fim da estação chuvosa. A análise macro-espacial da distribuição da anurofauna no PEMD evidenciou uma baixa similaridade entre as diferentes fitofisionomias amostradas. Na verdade, esta baixa similaridade faunística foi consequência da baixa eficiência de captura das armadilhas de interceptação e queda, o que resultou em uma baixa riqueza de espécies nas fitofisionomias estudadas. No entanto, alta similaridade na composição de espécies foi encontrada... / Occidental region of São Paulo state shelters the largest continuous remnant of Mesophytic Semideciduous Forest (Atlantic domain). Most of this region is legally protected by the Morro do Diabo State Park (MDSP), considered insufficient known but with probable biological importance concerning amphibians and reptiles. The present study aimed to study the spatio-temporal patterns of anuran distribution at MDSP, as well as to verify how environmental heterogeneity of breeding ponds influences on richness and anuran species composition. In general, recorded species (either calling males or tadpoles) occurred differentially among the studied breeding habitats, which was mainly related to the water flow and hidroperiod of breeding habitats. Thus, lotic, lentic permanent/semipermanent, and lentic temporary breeding habitats presented different anuran species composition. Temporal distribution of individuals was restricted to the moist and hot months (with exception to one species that occurred during the dry and cold months), resulting in a high temporal overlap of calling males and tadpoles distribution. Groups of species distributed differentially through the hot and moist months, where typical species of beginning, middle, and end of the rainy season could be identified. A macro-spatial analysis of anuran distribution evidenced low similarity among different sampled phytophysiognomies. Actually, the low faunistic similarity is rather a consequence of the low efficiency of capture by pitfall traps with drift fences, resulting in low species richness in the phytophysiognomies studied. However, a high similarity on species composition was found only among the most preserved areas of MDSP, due to the presence of Rhinella ornata. This species was indicative of the most preserved area of the MDSP, while two other species from the Leiuperidae family (Eupemphix nattereri and Physalaemus cuvieri)...
