A review of the allozyme data set for the Canarian endemic flora: causes of the high genetic diversity levels and implications for conservation.
Background and Aims Allozyme and reproductive data sets for the Canarian flora are updated in order to assess how the present levels and structuring of genetic variation have been influenced by the abiotic island traits and by phylogenetically determined biotic traits of the corresponding taxa; and in order to suggest conservation guidelines. Methods Kruskal-Wallis tests are conducted to assess...
متن کاملHybridization and Introgression Between the Endemic Phoenix canariensis and the Introduced P. dactylifera in the Canary Islands
The proportion of hybridization and introgression between the endemic Phoenix canariensis (Canarian date palm) and the introduced P. dactylifera (date palm), were characterized using a multilocus isozyme genotype, based on 17 isozyme loci. In order to evaluate the multilocus isozyme genotype’s ability to detect hybridization and introgression between the endemic Phoenix canariensis and the intr...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولHighly Decorated Lignins in Leaf Tissues of the Canary Island Date Palm Phoenix canariensis.
The cell walls of leaf base tissues of the Canary Island date palm (Phoenix canariensis) contain lignins with the most complex compositions described to date. The lignin composition varies by tissue region and is derived from traditional monolignols (ML) along with an unprecedented range of ML conjugates: ML-acetate, ML-benzoate, ML-p-hydroxybenzoate, ML-vanillate, ML-p-coumarate, and ML-ferula...
متن کاملAllozyme variation in the endangered insular endemic Castilleja grisea.
BACKGROUND AND AIMS Genetic diversity in Castilleja grisea, an endangered, perennial herb endemic to San Clemente Island, California was investigated. Subsequent to the elimination of goats from the island in 1992, many populations of C. grisea have reappeared and have been increasing in size. METHODS Nineteen populations were surveyed for their genotype at 19 allozyme loci. KEY RESULTS At ...
