Tight species cohesion among sympatric insular wild gingers (Asarum spp. Aristolochiaceae) on continental islands: Highly differentiated floral characteristics versus undifferentiated genotypes
The Amami Island group of the Ryukyu Archipelago, Japan, harbors extensive species diversity of Asarum in a small landmass. The fine-scale population genetic structure and diversity of nine insular endemic Asarum species were examined using nuclear DNA microsatellite loci and ITS sequences. High population genetic diversity (HS = 0.45-0.79) was estimated based on the microsatellites, implying o...
متن کاملPhylogenetic relationships in Asarum(Aristolochiaceae) based on morphology and ITSsequences.
A cladistic analysis of Asarum was conducted using data frommorphology and nuclear ribosomal internal transcribed spacer sequences(ITS) to examine the relationships among several groups of taxa thathave often been treated as segregate genera. Morphological andmolecular data were analyzed simultaneously for a set of 36 terminalsrepresenting the taxonomic, morphological, and geographic diversity ...
متن کاملSympatric bromeliad species (Pitcairnia spp.) facilitate tests of mechanisms involved in species cohesion and reproductive isolation in Neotropical inselbergs.
The roles of intra- and interspecific gene flow in speciation and species evolution are topics of great current interest in molecular ecology and evolutionary biology. Recent modelling studies call for new empirical data to test hypotheses arising from the recent shift from a 'whole-genome reproductive isolation' view to a 'genic' view of species and speciation. Particularly scarce (and thus of...
متن کاملAn Evolutionary Analysis of Insular and Continental Species.
-In four tetraploid (n = 36) varieties of cultivated Gaillardia aristata the last premeiotic mitosis is shown to be similar to any other mitosis, each anaphase and telophase chromosome containing two chromonemata spiraled in the same direction and about each other. The last division before meiosis is located by finding delayed somatic mitoses in sporogenous tissue of an anther sac which is cons...
متن کاملPathogenic Leptospira spp. in Wild Rodents, Canary Islands, Spain
To the Editor: Leptospirosis is a major emerging infectious disease with a worldwide distribution (1). It is a systemic disease of humans and domestic animals (2). Regarded globally as a zoonosis because it is acquired by humans from contact with animals or from water contaminated with the urine of infected animals, it is presumed to be the most widespread zoonotic disease in the world (1,2). S...
