Bergmann's Rule In Ectotherms: A Test Using Freshwater Fishes, Mark C. Belk, Derek D. Houston
Bergmann's Rule In Ectotherms: A Test Using Freshwater Fishes, Mark C. Belk, Derek D. Houston

Understanding patterns of variation in body size within and among species is a central question in evolutionary ecology (Schlichting and Pigliucci 1998). The most well known pattern of variation in body size is Bergmann's rule (Bergmann 1847; Mayr 1956). The intraspecific version of Bergmann's rule holds that within endothermic species, body size increases with increasing latitude (or decreasing temperature; Blackburn et al. 1999; Ashton et al. 2000). In general, mammals conform to this rule (Ashton et al. 2000).

Isolation And Characterization Of Atriplex Hortensis And Sweet Chenopodium Quinoa Starches, K. H. Wright, K. C. Huber, Daniel J. Fairbanks, C. S. Huber
Faculty Publications
Starches from garden orach (Atriplex hortensis) and sweet quinoa (Chenopodium quinoa Willd. "Surumi") seeds were isolated, examined for compositional characteristics, and compared with bitter quinoa (Cheno-podium quinoa Willd.) starch. Garden orach and sweet quinoa seeds were similar in fat and ash contents, while garden orach seeds contained 10% more protein. Starches were isolated from seeds following a 12-hr soak in dilute alkaline solution using a series of grinding, screening, centrifugation, and washing steps. Isolated starches viewed by scanning electron microscopy yielded angular, polygonal granules 2 m in diameter. Starches displayed typical A-type crystalline packing arrangements as determined by X-ray powder …
Investigating The Mechanism Of Acoustically Activated Uptake Of Drugs From Pluronic Micelles, Ghaleb A. Husseini, Christopher M. Runyan, William G. Pitt
Investigating The Mechanism Of Acoustically Activated Uptake Of Drugs From Pluronic Micelles, Ghaleb A. Husseini, Christopher M. Runyan, William G. Pitt
Faculty Publications
This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and without the action of ultrasound, while drug uptake was increased with the application of ultrasound. Methods In this study, the amount of uptake of two fluorescent probes, Lysosensor Green (a pH-sensitive probe) and Cell Tracker Orange CMTMR (a pH-independent probe), was measured in HL-60 and HeLa cells. Results: The results of our experiments show that the increase in drug accumulation in the cells as a result of ultrasonication is not …
Quality Attributes Of Dried Milk Products Packaged For Long-Term Storage, Michelle A. Lloyd, J. Zou, H. Farnsworth, Oscar A. Pike
Quality Attributes Of Dried Milk Products Packaged For Long-Term Storage, Michelle A. Lloyd, J. Zou, H. Farnsworth, Oscar A. Pike
Faculty Publications
There is a market for dehydrated foods, such as nonfat dry milk (NFDM), that are packaged for long-term storage in case of natural disasters or other emergencies. To maintain quality and optimize shelf-life, NFDM must be properly processed from good quality milk, well-packaged (minimizing moisture, light and oxygen), and stored appropriately. Research is needed to determine the variation in quality that exists in dried milk products intended for retail sale. The objective of this research was to evaluate and compare the quality of several types of dried milk products packaged for long-term storage. Ten brands of dried milk products (5 …
Creation Of Three Nutritional Mixes Based On Amaranth (Amaranthus Caudatus) And Other Andean Crops For School-Aged Children (Cochabamba-Bolivia), Sandra Carola Delgadillo Barriga
Creation Of Three Nutritional Mixes Based On Amaranth (Amaranthus Caudatus) And Other Andean Crops For School-Aged Children (Cochabamba-Bolivia), Sandra Carola Delgadillo Barriga
Theses and Dissertations
In Bolivia we have three very valuable Andean grains: amaranth (Amaranthus caudatus), quinoa (Chenopodium quinua), and canihua (Chenopodium pallidicaule), which combined with cereals and legumes can become a complete and balanced food in order to combat the malnutrition that is so widespread in our region. In this study, various nutritional mixes were formulated, based on amaranth and other Andean crops, and the three best were chosen according to nutrition, palatability, and cost. They were: Andean Baby Food, Mixicereal, and Amaranth Cookie, which have an amino acid complement between 79% and 100% and give satisfactory amounts of protein, energy, and minerals …
Determination Of The Protein Fraction And Presence Of Antibodies In The Seminal Fluid Of Llama (Lama Glama), Francisco Flores Lopes
Determination Of The Protein Fraction And Presence Of Antibodies In The Seminal Fluid Of Llama (Lama Glama), Francisco Flores Lopes
Theses and Dissertations
At an international level, Bolivia possesses the largest population of llamas followed by Peru. This makes our country a power, in this renewable resource, to create and generate economic development primarily for the quality of llama meat which has nutritional properties superior to other species of animals used for food. The development of the investigation of llamas in our country has not been very far-reaching. In other countries, advances have been made for quite some time, specifically in the area of reproduction, which presents problems in bringing about an intensive repopulation due to the unique characteristics of llama copulation and …

Determination Of Protein Profile And Presence Of Antibodies In Llama Seminal Plasma (Llama Glama), Francisco Flores Lópes
Theses and Dissertations
Internationally, Bolivia has the largest llama population followed by Peru. This makes our country a power in this renewable resource for working and generating economic development. This is mainly because of the quality of llama meat, which has nutritional properties superior to other animal species. The development and research in our country of llamas is not very significant. But in other countries advanced studies have been done for years, specifically in the area of reproduction, which represents problems for intensive repopulation because of singular characteristics of semen and copulation. The present research work was done at the UAC in Tiahuanacu …

Fiber Performance And Quality Of Angora Rabbits (Oryctolagus Cuniculus) In Different Trims, Juan Jaime Blacutt Toledo
Theses and Dissertations
In 132 rabbits belonging to the Cunicola La Esperanza Farm of the city of El Alto in the department of La Paz, the principle physical characteristics of the angora rabbit fiber were determined in a period of 3 shearings. As such they were organized into 2 groups, clearly differentiated by their sex (female and male). The obtained fiber of the different shearings were weighed in order to determine the performance of each animal and subsequently analyzed the wool in the Experimental Station of Patacamaya, where they determined the diameter, length of hair and marrow composition. The results were subjected to …
