Monitoring the occurrence and distribution of rare fish species is essential, especially in a semi-closed basin such as Mediterranean Sea. Biologically interesting often represent fishing waste (being part by-catch) therefore are not retained, leading to huge gap data collection. Here we report about Ionian Sea Zu cristatus (Bonelli, 1819) specimen, mesopelagic from order Lampriformes considere...

Background: Histomoniasis is a disease caused by Histomonas meleagridis, flagellated protozoan that can cause severe necrotizing hepatitis and typhlitis in several bird species. The has cosmopolitan distribution. In experimental infection, peacocks (Pavo spp.) showed susceptibility to histomoniasis, however there are few reports on natural histomoniasis this northeastern Brazil, about its occur...

Theories concerning the mode of origin of peripheral nucleoli in amphibian oocytes have been examined and tested. In Triturus cristatus the giant fusing loops of the 3 shortest lampbrush bivalents resemble nucleoli when viewed in phase contrast and may be considered as possible sites of production of nucleoli. Giant fusing loops, however, differ from peripheral nucleoli in certain important res...

Myxomycetes are protists whose life cycle depends on aerially dispersed spores that germinate into motile myxamoebae, which then pair and fuse to form a larger, motile plasmodium. The plasmodium seeks out a suitable fruiting site (usually atop vegetative material or detritus) and transforms into fruiting bodies that release the spores. In this paper we report the first known instance of a myxom...

The structure of supernumerary limbs formed following 180° ipsilateral blastema rotations in the arm of the newt Triturus cristatus is analysed. Both the skeletal pattern and the muscle patterns are examined. As is the case after comparable experiments in the axolotl (see, for example, Maden & Mustafa, 1982) the extra limbs which form show a range of anatomies. Limbs symmetrical about the dorsa...

Denatured 3H-labelled DNAs containing Xenopus or human globin sequences hybridize to RNA transcripts on a single pair of lateral loops on lampbrush chromosome IX of Triturus cristatus carnifex, and to no other loops on this chromosome or the rest of the complement. However they do so, not because of the globin sequences in the probes, but rather because the plasmids from which the probes were p...
