Evaluating The Performance Of Leucaena Accessions For Agroforestry In Sub-Humid Environment, Southern Tanzania, A. E. Majule

Tanzania Journal of Science

The performance of Leucaena accessions on acid soils in eastern coast Tanzania for agroforestry was evaluated for three years. Plant tree parameters assessed were fodder yield and plant stem height, stem girth, the number of total branches and poles production. Also, Leucaena psyllid, a common pest threatening the plants was also counted. Soil parameters assessed were pH organic carbon, total nitrogen, exchangeable calcium and magnesium. Result showed significant difference in growth between Leucaena accessions. Leucaena leucocephal cv K8 and Leucaena diversifolia were able to grow fast reaching 4.7 and 3.3 m respectively within a period of three years. Leucaena diversifolia …

Spatial Variation In The Chemical Composition Of Natal Otholiths From A Reef Fish In The Galápagos Islands, Benjamin I. Ruttenberg, Robert R. Warner

Biological Sciences

Over the past decade, researchers have used variation in the chemical composition of fish otoliths (earstones) to address a number of ecological questions, such as stock assessment and assessing rates of movement of individuals among habitats or life-history stages. However, these methods have yet to be applied successfully to the study of larval connectivity, a major unanswered question in marine ecology. Accomplishing this task requires a reference collection of pre-pelagic natal otoliths and accurate measurement of the chemical signatures of otoliths cores of recruits. We analyzed the chemical composition of natal otoliths from near-term benthic eggs of a damselfish (Stegastes …

Temporal And Spatial Distribution Of Grazers And Kelp Phlorotannins In Kachemak Bay, Alaska, Angela M. Dubois

Marine Biology

The potential influence of grazers on the density and distribution of kelp thalli is substantial and may be mediated by kelp phlorotannins serving in a defensive role. The purpose of this study was to determine how temporal and spatial phlorotannin patterns in four kelp species in Kachemak Bay, Alaska, are influenced by density and distribution of the gastropod grazer Lacuna vincta and environmental variables. Temporal phlorotannin patterns from June 2004 through December 2005 were mainly explained by the life history of particular kelp species as well as strong correlations with light attenuation and nitrate concentration. The Optimal Defense Theory of …

Long-Term Effects Of Tebuthiuron On Bromus Tectorum, Dana M. Blumenthal, Urszula Norton, Justin D. Derner, Jean D. Reeder

Western North American Naturalist

Use of herbicides to thin dense stands of Artemisia spp. (sagebrush) can free up resources for herbaceous plants and increase forage production, but may also facilitate weed invasion. We revisited a sagebrush thinning experiment in a north central Wyoming big sagebrush–grassland 11 years after application of tebuthiuron (N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-N-N′-dimethylurea) to determine the long-term responses of shrubs, available soil resources, perennial grasses, and Bromus tectorum L. (downy brome). Tebuthiuron reduced shrub cover by more than half, from 31% in untreated plots to 15% in treated plots (P = 0.002), and increased downy brome cover approximately 4-fold, from 0.9% in untreated plots …

Functional Trait Niches Of North American Lotic Insects: Traits-Based Ecological Applications In Light Of Phylogenetic Relationships, N. Leroy Poff, Julian D. Olden, Nicole K.M. Vieira, Debra S. Finn, Mark P. Simmons, Boris C. Kondratieff

College of Natural and Applied Sciences

The use of species traits to characterize the functional composition of benthic invertebrate communities has become well established in the ecological literature. This approach holds much potential for predicting changes of both species and species assemblages along environmental gradients in terms of traits that are sensitive to local environmental conditions. Further, in the burgeoning field of biomonitoring, a functional approach provides a predictive basis for understanding community-level responses along gradients of environmental alteration caused by humans. Despite much progress in recent years, the full potential of the functional traits-based approach is currently limited by several factors, both conceptual and methodological. …

Blood Parasite Infection In Mice From Cloud Forest And Nearby Disturbed Habitats, December 2006, Jesse A. Blumenstock

Monteverde Institute: Tropical Ecology and Conservation

Conversion of habitat by humans is pervasive, increasing, and the root of serious environmental problems. This study was performed to find differences in blood parasite infections of host mice in neotropical cloud forest versus nearby disturbed habitat. In Monteverde, Costa Rica, mice were trapped and examined for blood parasite species richness and abundance in primary forest and disturbed areas near houses. Twenty-eight mice were captured: 15 from the forest and 13 from the disturbed habitats. Eighty-six percent of these mice were of the species Peromyscus nudipes. There was no significant difference of parasite species richness between mice from the forest …

Responses To Salinity Of Color Polymorphs In Two Populations Of The Sea Star, Pisaster Achraceus, Viren Johann Perumal

Loma Linda University Electronic Theses, Dissertations & Projects

Pisaster ochraceus was analyzed to determine if varying salinities, animal color, or location affect the physiology of these sea stars. The three responses analyzed were aerobic respiration, ammonia excretion, and self-righting. The tested variables included two different color morphs (orange and purple) of P. ochraceus, two different locations (open coast and inland straits) in Washington State, and three salinities (22, 30, and 40 psu).

Wet mass-specific oxygen consumption rates were not significantly affected by color, location, or salinity, and Dry mass-specific oxygen consumption rates showed no significant differences for main effects, but a three-way interaction was identified. Similarly, ammonia …

An Interpolation Method For Stream Habitat Assessments With Reference To The Crystal Darter, Kenneth Richard Sheehan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Crystallaria asprella spp. (Elk River crystal darter) is documented only in Elk River, West Virginia. Little life history detail is known about this lotic, benthic-dependent species. Previous studies have led to a very basic understanding of the use of depth, flow and substrate of the crystal darter (Crystallaria asprella), and less is known about the Elk River crystal darter. Due to substrate-specificity in crystal darters (which reportedly bury in sand), a study concerning benthic stream habitat modeling was undertaken. Substrate and depth modeling using >5% of an area sampled at a resolution of 0.093 m2 square spatial data in a …

The Impact Of Organization Destruction On Social Capital Value, R. Drew Sellers

Student Scholarship

This paper links social capital dynamics and value with organization destruction. It produces the finding that organizational destruction may in some cases increase the value of social capital. A key theoretical contribution of this study is extending the metaphor of social capital to encompass asset recoverability. Based upon cases studies of 15 individuals who lived through the destruction of Arthur Andersen, this paper examines the persistence and value of an individual's social capital when an organization destructs. It explores the question, "Is the value of an individual's investment in organization-specific social capital a recoverable asset post-destruction?" Interviews with Andersen alumni …

Statistical Analysis Of Air Pollution Panel Studies: An Illustration, Holly Janes, Lianne Sheppard, Kristen Shepherd

UW Biostatistics Working Paper Series

The panel study design is commonly used to evaluate the short-term health effects of air pollution. Standard statistical methods for analyzing longitudinal data are available, but the literature reveals that the techniques are not well understood by practitioners. We illustrate these methods using data from the 1999 to 2002 Seattle panel study. Marginal, conditional, and transitional approaches for modeling longitudinal data are reviewed and contrasted with respect to their parameter interpretation and methods for accounting for correlation and dealing with missing data. We also discuss and illustrate techniques for controlling for time-dependent and time-independent confounding, and for exploring and summarizing …

Feasibility Of Developing Exposure Estimates For Use In Epidemiological Studies Of Radioactive Emissions From The Santa Susana Field Laboratory, Jan Beyea Ph.D.

Santa Susana Field Laboratory (SSFL)

This report provides exposure estimates to assist epidemiologists in deciding on the effectiveness of studies of radiation-induced disease around the Santa Susana Field Laboratory (SSFL). Developing such estimates was a difficult challenge, because the site is extremely complex from the meteorological perspective, there is limited information available about releases of radioactivity in the 1950s and 60s, and some meteorological data is withheld by the plant owner. As a result, the estimates in this report are limited to scoping calculations that carry a wide range of uncertainty, complicating their use for estimation of statistical power. Nevertheless, they represent the current state …

Book Review Of Twilight Of The Mammoths: Ice Age Extinctions And The Rewilding Of America By Paul S. Martin, Michael Fosha

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Applying ecological studies to the adaptations of prehistoric human hunter-gatherer groups has greatly increased our abilities to interpret effects of an ever-changing environment and our access to critical resources on these populations. The Pleistocene/Holocene transition, its climate and human genesis in the new world, draws intensive interest from a number of scientific communities. In Twilight of the Mammoths, Paul Martin adds his views, which are of no surprise, on the megafaunal extirpations during a cultural period referred to in North America as Clovis.

Liana Habitat Associations And Community Structure In A Bornean Lowland Tropical Forest, Saara J. Dewalt, Kalan Ickes, Reuben Nilus, Kyle E. Harms, David F.R.P. Burslem

Faculty Publications

Lianas (woody vines) contribute substantially to the diversity and structure of most tropical forests, yet little is known about the importance of habitat specialization in maintaining tropical liana diversity and the causes of variation among forests in liana abundance and species composition. We examined habitat associations, species diversity, species composition, and community structure of lianas at Sepilok Forest Reserve, Sabah, Malaysia in northeastern Borneo among three soil types that give rise to three distinct forest types of lowland tropical rain forest: alluvial, sandstone hill, and kerangas (heath) forest. Alluvial soils are more nutrient rich and have higher soil moisture than …

A Review Of Urinary Stone Analysis Techniques, Rabie E. Abdel-Halim, Mostafa R. Abdel-Halim

Knowledge of the chemical composition and structure of urinary stones is of great value in the choice of treatment and prevention of recurrence. This is a brief review and a comparative study of the principles and practical application of various chemical and physical techniques used for urinary stone analysis. The different methods of classifying and grouping urinary stones by results of chemical analytic techniques are, also, compared and evaluated. In addition to reviewing various techniques used for the in-vitro analysis of removed stone samples, the newly emerging physical and radiological techniques for the in-vivo intact-stone analysis are, also, evaluated. These …

Evaluating The Long-Term Metacommunity Dynamics Of Tree Hole Mosquitoes, Alicia M. Ellis, L. Philip Lounibos, Marcel Holyoak

Dartmouth Scholarship

Four different conceptual models of metacommunities have been proposed, termed “patch dynamics,” “species sorting,” “mass effect,” and “neutral.” These models simplify thinking about metacommunities and improve our understanding of the role of spatial dynamics both in structuring communities and in determining local and regional diversity. We tested whether mosquito communities inhabiting water-filled tree holes in southeastern Florida, USA, displayed any of the characteristics and dynamics predicted by the four models. The densities of the five most common species in 3–8 tree holes were monitored every two weeks during 1978–2003. We tested relationships between habitat variables and species densities, spatial synchrony, …
