Fish Production in Streams With and Without Natural Broan Trout Populations

Brown trout (Salmo trutta) have been introduced into the waterways throughout the United States, including Pennsylvania, since the 1800’s. They may have limited interactions with native fish species in regions where they do not reproduce successfully, but where they do concerns have arisen regarding the impact they have on native species. Are brown trout having a negative effect on the native fish? If so, could they be outcompeting the natives to the point of localized extirpation? This project compared fish communities, densities, biomass and production in two similar stretches of stream in the White Clay Creek, one known to hold brown trout (the East Branch) and the other without (the Middle Branch). Fish in each branch were collected in June and October 2009 using backpack electrofishing equipment to determine species composition and abundance, population densities and community diversity. Fish were aged using scales and further examination revealed biomass and production of the species present. The fish communities within the branches were stable between June and October (Jaccards index = 0.75 for both branches), but differed between branches (Jaccards index = 0.64 in June and 0.58 in October). The stream without brown trout showed much lower density, biomass, and production of most species, which went counter to our hypothesis that fish would show lower levels of these factors in the presence of brown trout. Only the common shiner and longnose dace showed effects in each of these categories while favoring the branch without brown trout over the branch with brown trout. Although the results do show a possible negative correlation between these species and the brown trout, our study design did not allow us to rule out other factors. Also, the fewer number of fish in the Middle Branch as compared to the East Branch leads us to believe that something may be wreaking havoc with the natural balance of this section (e.g. land-use changes, environmental stressors or climatic factors). Continued research regarding brown trout interactions on the East Branch and stream quality of the Middle Branch is highly recommended

Effect of dietary omega-3 fatty acid deficiency on heart rate variability in hooded rats

Introduction: Recent reports in adult humans suggest that heart rate variability is modulated by the concentration of omega-3 polyunsaturated fatty acids (PUFA) contained in blood cell membranes. Material and methods: Hurst analysis of ECG data was conducted on 12 male adult hooded (Long-Evans) rats, representing the 3rd generation to be fed diets that were either deficient in, or supplemented with, omega-3 PUFA. ECG data were obtained from surface electrodes and 4000 beats were analyzed for each animal. Results: Dietary manipulation, despite leading to large changes in tissue omega- 3 PUFA levels, did not significantly affect the complexity of heart rate dynamics, with Hurst exponent (H) values of 0.15&plusmn;0.02 and 0.12&plusmn;0.03, for animals fed omega- 3 fatty acid-adequate and -deficient diets, respectively. Mean heart rate was also unaffected by the diets. A power calculation revealed that about one hundred animals per group would have been required to avoid a type II error. Conclusions: According to this model of dietary PUFA manipulation, omega-3 fatty acids are unlikely to exert a large effect on the autonomic functions that control heart rate variability. Prospective studies into the effect of omega-3 fatty acids on HRV should consider the need for large sample size as estimated by the results contained in this report.<br /

Technology in the Elementary Art Program

The advancement of technology use in todays\u27 schools has provided teachers with new teaching resources. This applies to all teachers in every curricular area at every grade level. One area of instruction in which technology has had an overwhelming effect is the visual arts. Technology has created a new art form with which artists young and old may express themselves visually. Technology has also provided art educators with a unique teaching tool to promote visual learning

El Tango y los Bailes del Internado 1914 - 1924

De todas las actividades profesionales, pocas tuvieron tan estrecha relacióncon el tango como la medicina. Los Bailes del Internado fueronorganizados desde 1914 por los estudiantes internos de la Facultad deMedicina. Estaban destinados a amenizar, una vez al año, la velada en elDía de la Primavera, coincidente con el Día del Estudiante. Se inspirabanen los que realizaron los estudiantes de medicina franceses en la salaBullier en París durante más de un siglo y que sólo fueron interrumpidosen 1870 y 1914 debido al inicio de la Guerra Franco-prusiana y de laPrimera Guerra Mundial, respectivamente.El presente trabajo describe los bailes realizados en Buenos Aires, relacionándoloscon sus inspiradores en París, tomando como ejemplo el quetuvo lugar en dicha ciudad en la sala Bullier en 1913, un año antes delprimer baile homónimo en nuestro país
