Grazing-related, intraspecific, morphological variation was studied in four North American grasses (Bouteloua gracilis, Agropyron smithii, Schizachrium scoparium, and Andropogon gerardii) from eight locales in Wind Cave National Park, South Dakota: three locales currently occupied and heavily grazed by prairie dogs (Cynomys ludovicianus), colonized (since settlement) for 2-100 years, where native ungulates concentrate grazing activities; an extinct colony locale from which prairie dogs were removed 30 yeras previously, moderately to lightly grazed by ungulates; two noncolony locales, moderately to lightly grazed by ungulates; and two locales from within a 50-yeras-old grazing exclosure, with no known history of grazing by prairie dogs nor any recent grazing by ungulates. Data were collected both in situ and in common environments. Active-colony plants were more frequently and more heavily grazed than those at other grazed localles. In situ, plants from heavily grazed populations were smaller and more prostrate than those from populations, with little or no grazing (including the extinct colony) and interpopulation variation corresponded to current grazer use. After several growing seasons in common environments, there were still significant interpopulations differences; however, variationn often corresponded with grazing history. Although differences between active-colony and noncolony plants were somewhat reduced (indicanting some phenotypic plasticity), active-colony plants were still smaller and more prostrate. However , extinct-colony plants more closely resembled active-colony plants than noncolony plants. Morphological variation among these populations is the result of more than simple grazer use; historical factors and the dynamics nature of the grazing regimes are also contributing factors.

Given the need to satisfy the demand for fish consumption, canned native fish has emerged as a market alternative, but it is necessary to determine the nutritional aspects of this product. The aim of this study was to characterise the lipid profile and evaluate the nutritional quality of matrinxã preserved in vegetable oil and compare these results with freshwater sardines obtained from the same type of processing and canning. Matrinxã species had higher protein content than sardines, but sardines had higher levels of moisture, lipids and total minerals. The predominant fatty acid in the canned fish samples was linoleic acid, followed by oleic acid and palmitic acid. In terms of nutritional quality, matrinxã showed higher indices of atherogenicity and thrombogenicity and lower values of the following ratios: hypocholesterolemic and hypercholesterolemic fatty acids; polyunsaturated/saturated and omega 6/omega 3 ratio in relation to sardines. In view of the results, it can be affirmed that Matrinxã, from a nutritional point of view, presents itself as a good alternative for the canned fish industry. |
