The Physiological Effects Of The Guanylin Peptides In The Intestine Of The Gulf Toadfish (Opsanus Beta), Ilan M. Ruhr

Open Access Dissertations

The findings in the present dissertation describe the regulatory role the guanylin peptides play in seawater teleost intestinal physiology through the use of the model organism, the Gulf toadfish (Opsanus beta). For the majority of the findings, renoguanylin (a guanylin peptide exclusive to teleost fish) is used as an experimental tool and elicits responses in the posterior intestine and rectum of the Gulf toadfish, but does not affect the anterior intestine. Both the posterior intestine and rectum display secretory short-circuit currents, reversed transepithelial potentials, and increased conductance in response to renoguanylin stimulation. These changes are driven primarily by chloride secretion …

Quantifying The Top-Down Effects Of Grazers On A Rocky Shore: Selective Grazing And The Potential For Competition, Diana Lascala-Gruenewald, Luke Miller, Matthew Bracken, Bengt Allen, Mark Denny

Faculty Publications, Biological Sciences

The effect of grazers on the diversity, distribution, and composition of their principal food source has rarely been described for the high intertidal zone of rocky shores, a model system for studying the potential effects of climate change. Along rocky, wave-swept shores in central California, the microphytobenthos (MPB) supports diverse assemblages of limpets and littorine snails, which, at current benign temperatures, could potentially partition food resources in a complementary fashion, thereby enhancing secondary productivity. Two limpet species in particular, Lottia scabra and L. austrodigitalis, may partition components of the MPB, and are likely to affect the composition of the …

Geographic Range Limits In Salamanders: Interactions Between Physiological And Behavioral Systems, Timothy Allen Clay

Theses and Dissertations

Understanding the relationship between species distributions and their underlying mechanisms is a major question in ecology and evolutionary biology. The mechanisms involved and the degree to which they affect distributions vary among and within species. Examining the diversity of these mechanisms through behavioral, physiological, and integrative approaches can further our knowledge of the evolution of such traits and the maintenance of biodiversity and geographic distributions. Many of these traits may be conserved after speciation, therefore examination should be thorough, involve many species, and incorporate a phylogenetic approach. The salamanders in the genus Plethodon are an ideal system to test predictions …

Safety Data Management: Gathering And Using The Data, Robert A. Perkins, F. Lawrence Bennett

INE Project Reports

How are roadway crash data acquired, stored, and utilized in engineering and management decisions regarding highway projects? This research answers that question by interviewing the engineers and professionals involved with that safety data management from six states and asking – How are safety (crash) data acquired and used in their states. Since most safety projects are funded by the federal FHWA, through the HSIP, the general flow of the safety data is similar in the states interviewed. But there are many differences in details, especially the computer hardware and software. The methods of data movement between the responder and the …

A Framework For Decision-Making In Cases Of Invasive Species, Peter A. Khaiter, Marina G. Erechtchoukova, Sina Roushan

International Congress on Environmental Modelling and Software

Invasion of nonindigenous species is one of the most pressing global challenges, causing substantial environmental, economic and social harm. Invasion of alien species alters the composition, structure and functioning of invaded ecosystems as well as the services they generated before the invasion. Decisions about the management of invasive cases are inherently difficult because of the multifactorial and multiattribute scope of the problem. In particular, the resilience limits of invaded ecosystems to fully recover original, pre-invaded states remain unclear. To facilitate management efforts, decision-makers and environmental practitioners require a framework integrating relevant knowledge and acting as a supporting expert system. The …

Simulating Spatial Changes In Vegetation-Livestock Interactions Under Different Landscape Structures: A Multi-Agent System Applied To Agro-Pastoral Territories, Mamadou Sané, Jonathan Vayssières, Myriam Grillot, Alassane Bah, Alexandre Ickowicz

International Congress on Environmental Modelling and Software

Free-range and common-grazing ruminants play a major role in the functioning and the provision of ecosystem services by agro- and silvo-pastoral ecosystems in sub-Saharan Africa. To assess how landscape structure affects the nature of environment-herd-services interactions, this paper describes a Multi-Agent System (MAS) that simulates daily herd movements in a dynamic environment. The model is used to study how the overall productivity of an agricultural territory is affected by the spatial organization of its different landscape units. The originality of this model lies in fine representation, in hourly time steps, of a herd’s movements and activities over the seasons depending …

Actor-Based System Dynamics Modelling Of Win-Win Climate Mitigation Options, Dmitry V. Kovalevsky, Klaus Hasselmann

International Congress on Environmental Modelling and Software

The actor-based system dynamics approach to Integrated Assessment modelling (IAM), seen as further development of ‘traditional’ system dynamics economic modelling, however with a stronger emphasis on describing the decision making of key aggregate economics actors, is a promising methodology for developing the comprehensive IAMs of next generations. The present paper is focused on application of actor-based system dynamics models to identification and assessment of win-win opportunities of climate mitigation policies. Modelling results outlined suggest that in a multi-country world properly designed climate mitigation policies can unite rather than divide different nations, therefore putting under question the ‘juggernaut’ of much discussed …

Plant Trait-Based Assessment Of The Pasture Simulation Model, Anne-Isabelle Graux, Katja Klumpp, Shaoxiu Ma, Raphaël Martin, Gianni Bellocchi

International Congress on Environmental Modelling and Software

We used a functional trait-based plant classification to improve the plant module of the biogeochemical grassland model PaSim. Based on four main classes (A, B, C, D) and two derived types (b, d) covering a gradient from high to low productive/fertile grassland vegetation types, we derived new classes of model plant parameters representing an evolution of a previous parameterization obtained by calibration without considering any plant diversity. Illustrative results are presented for the French grassland site of Laqueuille, by comparing two grazing management treatments: high animal stocking rate and fertilisation “intensive” (type B) and low animal stocking rate “extensive” (type …

International Trade Effects Of Regional Economic Integration In Africa: The Case Of The Southern African Development Community (Sadc), Mengesha Yayo, Sisay Asefa

International Journal of African Development

Empirical studies on regional economic integration process in Africa exhibit sluggish progress, and there by limited level of intra-trade. The existing literature in Africa, particularly in the Southern African regional integration bloc, has neglected the effects of regional economic integration dealing with disaggregated data. This study analyzes trade creation and diversion effects of the Southern African Development Community (SADC) using disaggregated data. The investigation estimates an augmented gravity model using panel data and random effect estimator methods applying instrumental variables where needed.

The results show that intra-SADC trade is growing in the fuel and minerals and the heavy manufacturing sectors …

Current Situation Of Agricultural Trade: What Effects Does It Have On Food Security In Africa?, Ismaelline Eba Nguema

International Journal of African Development

The history of food policy in Africa started with the beginning of independence with the adoption of the strategy based on the planned development model. However, the financial and administrative planning requirements were felt quickly. By the early 80s, the debt crisis led African economies to abandon the policy of self-sufficiency and to adopt a so-called liberal agro-food strategy. In this context, food security based on external trade and its requirements became integral parts of structural adjustment programs. Thus, Africa took a stand before the rest of the world in the controlling of extraversion. Despite mixed results, in January 1995, …

Reducing Marginalization Of Fishermen Through Participatory Action Research In The Zambezi Valley, Zimbabwe, Bernard Manyena, Andrew E. Collins, Frank Mudimba, Danisa Mudimba

International Journal of African Development

Equitable sharing of fishing resources has been the major source of tension between Zambezi Valley communities and the Zimbabwe government authorities since the 1950s following the Kariba Dam-induced resettlement. Using participatory action research, it was found that the fishing license system and criminalization of fishermen were the major sources of tension between fishermen and government authorities. Engaging with government authorities to address these tensions, fishermen were recognized as partners in the fishing industry. The conclusion was that enhancing community agencies through participatory action research would be fundamental towards creating socially just and equitable arrangements that could emancipate marginalized communities from …

Hdac6 Inhibition Prevents Tnf-Α-Induced Caspase 3 Activation In Lung Endothelial Cell And Maintains Cell-Cell Junctions, Jinyan Yu, Mengshi Ma, Zhongsen Ma, Jian Fu

Center for Research on Environmental Disease Faculty Publications

Pro-inflammatory mediators such as TNF-α induce caspase activation in endothelial cells, which leads to degradation of cellular proteins, induction of apoptotic signaling, and endothelial cell dysfunction. New therapeutic agents that can inhibit caspase activation may provide protection against inflammatory injury to endothelial cells. In the present study, we examined the effects of selective histone deacetylase 6 (HDAC6) inhibition on TNF-α induced caspase 3 activation and cell-cell junction dysfunction in lung endothelial cells. We also assessed the protective effects of HDAC6 inhibition against lung inflammatory injury in a mouse model of endotoxemia. We demonstrated that selective HDAC6 inhibition or knockdown of …

© 2016 The Author(s). Light is known to excite photosensitizers (PS) to produce cytotoxic reactive oxygen species (ROS) in the presence of oxygen. This modality is attractive for designing control measures against animal diseases and pests. Many PS have a proven safety record. Also, the ROS cytotoxicity selects no resistant mutants, unlike other drugs and pesticides. Photodynamic therapy (PDT) refers to the use of PS as light activable tumoricides, microbicides and pesticides in medicine and agriculture. Here we describe "photodynamic vaccination" (PDV) that uses PDT-inactivation of parasites, i.e. Leishmania as whole-cell vaccines against leishmaniasis, and as a universal carrier to …
