Redescription of Capitella capitata (Fabricius) from West Greenland and designation of a neotype (Polychaeta, Capitellidae)
Capitella capitata (Fabricius, 1780), the type species of the genus, was originally described from the SW coast of Greenland; however, current definitions of the species are largely based on Eisig (1887), who described specimens from Naples on the Mediterranean coast. Eisig’s excellent account of the morphology of a sexually dimorphic species has subsequently been applied to specimens collected...
متن کاملMetabolism of the polycyclic aromatic hydrocarbon fluoranthene by the polychaete Capitella capitata species I.
Previous studies have shown that infaunal deposit feeders may enhance the loss of organic contaminants from sediments. However, the extent to which this occurs as a result of sediment microbial stimulation, porewater flushing, or biotransformation by infauna remains unclear. The purpose of this study was to determine whether the infaunal polychaete Capitella sp. I is able to metabolize the poly...
متن کاملDemystifying the Capitella capitata complex (Annelida, Capitellidae) diversity by morphological and molecular data along the Brazilian coast
The sibling species of Capitella capitata are globally known for their tolerance to disturbed habitats and the C. capitata complex is often used as an ecological indicator. A recent re-description proposed that C. capitata, originally described in Greenland is restricted to the Artic and Subarctic regions. Given their ecological relevance, we conducted a morphological and molecular analyses bas...
متن کاملCaryologic Study of Some Species of )Astragalus spp.( in Different Habitats of Iran
Astragalus with more than 800 species is one of the largest plant species in Iran and most of its species are medicinal and native. In this study, karyotypic characteristics of 21 populations from 13 species including A. vegetus, A. iranicus, A. vanillae, A. chrysostachys, A. glycyphyllos, A. bombycinos, A. campylorrhynchus, A. macrourus, A. caragana, A. ebenoides, A. pseudocyclophyllus, A. ste...
متن کاملVariation in sulfide tolerance of photosystem II in phylogenetically diverse cyanobacteria from sulfidic habitats.
Physiological and molecular phylogenetic approaches were used to investigate variation among 12 cyanobacterial strains in their tolerance of sulfide, an inhibitor of oxygenic photosynthesis. Cyanobacteria from sulfidic habitats were found to be phylogenetically diverse and exhibited an approximately 50-fold variation in photosystem II performance in the presence of sulfide. Whereas the degree o...
