Influence of host anemia on blood-feeding rate and egg production of Aedes aegypti (L.) (Diptera : Culicidae)

Creator:: Shieh, Jong-Neng
Abstract:: I tested a theoretical model proposing that anemia favors transmission of blood-borne parasites to vectors by accelerating the blood-feeding rate. Using Aedes aegypti, the yellow fever mosquito, initially, I was not able to confirm this phenomenon either in an artificial or a live system; anemia did not correlate with blood-feeding...

Antibacterial activities in the salivary glands of female mosquitoes Aedes aegypti

Creator:: Deng, Lanqian
Abstract:: Antibacterial activities in the salivary glands of female mosquitoes Aedes aegypti were investigated in this study. The mean salivary bacteriolytic activity, during a period of 14-day of female mosquitoes exposed to five different concentrations of Gram-positive bacteria Micrococcus lysodeikticus in the sucrose meal, was detected by a lysoplate method. A...

Stability and complexity : a reappraisal of the Competitive Exclusion Principle

Creator:: Duran, Israel N.
Abstract:: Elton (1927) realized that, intuitively at least, nature was complex and stable. And that the last property contributed to the first. This idea was challenged mathematically by Gardner and Ashby (1970) and May (1972), and in the years following various models have attempted to reconcile these opposing views. Unlike previous...

A model of trophic evolutionary pathways

Creator:: Morris, A. Kimo
Abstract:: Calow (1983) realized that differences between parasites and their free-living relatives can be explained by the differences in nutrient richness. I propose a model that is based on Calow's idea which identifies the relative position of different trophic strategies (e.g. predation, grazing, parasitism and others) based on (1) the differences...

The European union directive on packaging and packaging waste management : potential effect on seafood exporters of the Pacific Northwest

Creator:: Latriche, Philippe
Abstract:: This study examines the impact on Pacific Northwest seafood exporters of the European Union Directive on packaging and packaging waste management. The study of the official text of the proposed Directive was the starting point of our analysis. This allowed us to give a presentation of the EU Directive and...

Mortality threshold for juvenile Chinook salmon (Oncorhynchus tshawytscha) in an epidemiological model of Ceratomyxa shasta

Creator:: Ray, R. Adam
Abstract:: The myxozoan parasite, Ceratomyxa shasta, is the most significant pathogen of juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Klamath River, CA, USA. This parasite requires two hosts - a freshwater polychaete (Manayunkia speciosa) and a salmonid - to complete its life cycle. The complex life cycle and large geographic area...

Biology of the two external Acarapis species of honey bees : Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler (Acari: Tarsonemidae)

Creator:: Ibay, Lilia Armendez
Abstract:: The biology of the two external Acarapis mites of honey bees, Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler was studied. It was observed that both Acarapis species have similar developmental period (8-9 days) with males emerging earlier than females. Mite load and infestation rate of A. dorsalis decreased as bees...

Investigation of Nematocyst Discharge in Parasitic Cnidarians (Myxozoa)

Creator:: Americus, Benjamin E.
Abstract:: Myxozoans are an enigmatic group of obligately parasitic, microscopic cnidarians. They diverged from their free-living relatives over 600 million years ago and have highly reduced genomes. However, they have retained nematocyst stinging cells which characterize the phylum Cnidaria. Free-living cnidarians utilize this cellular weaponry for defense and predation whereas the...

The Use of Terrestrial Laser Scanning and Computer Vision in Tree Level Modeling

Creator:: Gabriel, Richard S.
Abstract:: Laser Scanning represents a new opportunity in forestry to effect meaningful change in the methods used for collection and analysis of inventory data. With the ability to collect spatial information in 360 degrees, while fluidly tracking the sensor and building the final point cloud, large tracks of terrestrial LiDAR based...
