Global Diversity of Brittle Stars (Echinodermata: Ophiuroidea)
This review presents a comprehensive overview of the current status regarding the global diversity of the echinoderm class Ophiuroidea, focussing on taxonomy and distribution patterns, with brief introduction to their anatomy, biology, phylogeny, and palaeontological history. A glossary of terms is provided. Species names and taxonomic decisions have been extracted from the literature and compi...
متن کاملPresence of spawn-inducing pheromones in two brittle stars (Echinodermata: Ophiuroidea)
Possible roles of pheromones in inducing spawning of 2 brittle stars, Ophiocoma dentata and Ophiocoma scolopendrina, were tested with gonad homogenates. In both species, the ovary homogenate induced conspecific, competent males to spawn. The potential pheromone was speciesspecific and had no effect on conspecific females. The testis homogenate did not have any effect. Of the males 50% could be ...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Population genetic structure of North American Ophiactis spp. brittle stars possessing hemoglobin
With the discovery of previously unreported populations of hemoglobin-possessing Ophiactis from the Texas coast in the Gulf of Mexico, an investigation into its population structure, including populations of O. simplex from the PaciWc coast of California and O. rubropoda from the Atlantic coast of Florida, was undertaken using DNA sequence data from the mitochondrial COI gene. The reconstructed...
متن کاملcoordination of protective schemes in distribution and subtransmission systems including distributed generation
نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
