Isozyme Polymorphism in Natural Populations of a Liverwort, PLAGIOCHILA ASPLENIOIDES.
Assays of five Polish populations of Plagiochila asplenioides (Hepaticae, Plagiochilaceae) for peroxidase isozymes revealed three bands differing in electrophoretic mobility. The phenotypes observed appear to be governed by three loci; each locus has two alleles, one of which produces a band and the other no band, i.e., the second allele is silent, or null. Marked variability in enzyme phenotyp...
متن کاملBreeding biology of Grey Wagtail Motacilla cinerea canariensis on Tenerife, Canary Islands
The paper reports on the breeding biology of the endemic subspecies of the Grey Wagtail in a human transformed area (banana plantations) on Tenerife (Canary Islands). Clutch size (3.96 ± 0.6) was lower than in continental zones, probably because of the climatic stability of the islands. Furthermore, the distance from the nest to the nearest water source and the length of the breeding season (la...
متن کاملOpportunistic nectar-feeding birds are effective pollinators of bird-flowers from Canary Islands: experimental evidence from Isoplexis canariensis (Scrophulariaceae).
Insular floras, characterized by simple pollination networks, sometimes include novel mutualistic agents such as nonspecialist nectarivores. In this study we confirmed the effective pollination of Isoplexis canariensis by opportunistic nectar-feeding birds in Tenerife, Canary Islands, Spain. This plant is among the ornithophilous species of the Canarian flora that lack past and present speciali...
متن کاملGenetic Diversity of Natural Populations of Medicago truncatula in Morocco Using Isozyme Polymorphism
Nine natural populations of Moroccan Medicago truncatula were analysed using enzymatic markers to identify useful phytogenetic resources for their integration in programmes of safeguard and conservation. Starch gel electrophoresis was used to examine genetic variation within and among natural populations. According to our estimates of genetic variation analysed by five loci detected for three e...
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...
