Isozyme polymorphisms provide evidence of clinal variation with elevation in Nothofagus pumilio.
Variable physical conditions along elevational gradients strongly influence patterns of genetic differentiation in tree species. Here, the hypothesis is tested that different growth forms of Nothofagus pumilio, which characterizes the subalpine forests in the southern Andes, will display continuous genetic variation with elevation. At each of four elevational strips in three different mountain ...
متن کاملBias-Correction Fuzzy C-Regressions Algorithm
In fuzzy clustering, the fuzzy c-means (FCM) algorithm is the most commonly used clustering method. However, the FCM algorithm is usually affected by initializations. Incorporating FCM into switching regressions, called the fuzzy c-regressions (FCR), has also the same drawback as FCM, where bad initializations may cause difficulties in obtaining appropriate clustering and regression results. In...
متن کاملChemical composition and antimicrobial properties of Teucrium polium essential oil collected from dena mountain
Background: Teucrium polium is a medicinal plant used as an herbal plant for antispasmodic and antimicrobial properties. Objective: This study aimed to evaluate the effect of the essential oil of T. polium against fungal, bacterial strains, and Giardia lamblia. Also, chemical analysis of the essential oil of T. polium was analyzed by GC/MS. Methods: Teucrium polium was collected from the De...
متن کاملEquilibrium-Line Altitudes of Late Quaternary Glaciers in the Zardkuh Mountain, Iran
Equilibrium-line altitudes (ELAs) of former glaciers in the Zardkuh Mountain of the Zagros Mountain Range were reconstructed from glacial-geologic data on former ice limits by using various methods. In the study area various types of glacial landforms such as outwash fans, moraines and well developed glacial cirques are observed. The results suggest that ELA were depressed 1433 m below to prese...
متن کاملQSAR models to predict physico-chemical Properties of some barbiturate derivatives using molecular descriptors and genetic algorithm- multiple linear regressions
In this study the relationship between choosing appropriate descriptors by genetic algorithm to the Polarizability (POL), Molar Refractivity (MR) and Octanol/water Partition Coefficient (LogP) of barbiturates is studied. The chemical structures of the molecules were optimized using ab initio 6-31G basis set method and Polak-Ribiere algorithm with conjugated gradient within HyperChem 8.0 environ...
