Extensive gene flow within sibling species in the deep-sea Beryx splendens
Molecular markers allow insights into the population biology and ecology of deep-sea organisms, which are usually hardly accessible to direct observation and poorly known. Such a study was undertaken here for the deep-sea fish Beryx splendens, a species of growing interest to fisheries. B. splendens populations were sampled on seamounts and continental margins in the southwestern Pacific (New C...

متن کاملPathology of Piscinoodinium sp. (Protozoa: Dinoflagellida), parasites of the ornamental freshwater catfishes Corydoras spp. and Brochis splendens (Pisces: Callichthyidae).
Piscinoodinium sp. (Protozoa, Dinoflagellida) was commonly found on routine smears of samples of Brochis splendens and Corydoras spp. imported into Britain from South America, and on samples of the same group of fish examined at the exporters' holding facilities in Brazil. Infected fish had trophonts of different sizes on the gills and skin. In histological sections of the skin, the trophonts w...
متن کاملHeteromorphic a Chromosomes of the Tomato Differing in Satellite Size.
In cultivated tomato plants which were largely but not exclusively derived from triploids, chromosomes of two distinct sizes were found associated with the nucleolus in the pollen mother cells. Since a trivalent was found on the nucleolus in the simple trisomic type, triplo-A only, evidently it is the A or first chromosome which is dimorphic. At somatic metaphase this chromosome has a distinct ...
متن کاملHeteromorphic Change of Adult Fibroblasts by Ribonucleoproteins
Cultures of subcutaneous areolar fibroblasts from adult rats, when confronted in vitro with microsomes from rat liver or kidney, are changed heteromorphically so as to resemble cultures of nervous tissue. Similar effects follow exposure to the deoxycholate-insoluble fraction of microsomes, and to purified RNA from rat liver or from yeast. An equivalent ribonucleoside mixture has no heteromorphi...
