چکیده

The morphologies of the cerebral ganglia (brains) of three infraorders of the decapod crustaceans (Astacura-crayfish; Brachyura-crabs; Palinura-spiny lobsters) are described. A common nomenclature is proposed for homologous nerve roots, brain regions, tracts, commissures, neuropils, and cell body clusters.

Comparative Analysis of Neurogenesis in the Central Olfactory Pathway of Adult Decapod Crustaceans by Irt Viva BrdU Labeling

To examine the distribution of neurogenesis in the central olfactory pathway of adult decapod crustaceans, we labeled, in vivo, six species of decapod crustaceans representing most infraorders (shrimps, spiny lobsters, clawed lobsters, crayfish, hermit crabs, true crabs) with the proliferation marker 5-bromo-2’-deoxyuridine (BrdU). In all tested species a group of small, neuron-like nuclei in t...

The aim of this study was to evaluate the accumulation of Lead, Copper, Cadmium and Mercury in the soft tissues of brown algae (Sargassum ilicifolium) and muscle of spiny lobster (Panulirus homarus) in a five different stations along the northern coasts of the Oman Sea during pre and post monsoon seasons. A number of 50 specimens of each sample were collected from stations of Jask port, Darak ...

Discovery of four natural clones in a crayfish species Procambarus clarkii

Self-cloning is quite rare in shrimp, lobsters, crayfish and crabs. Here we report the discovery of four natural clones of red swamp crayfish (Procambarus clarkii), each containing 2-6 genetically identical individuals, during the genotyping of 120 individuals with five microsatellites. The four clones were heterozygote at most of the five microsatellite loci. Phylogenetic analysis using micros...

Movement patterns and shelter choice of spiny-cheek crayfish (Orconectes limosus) in a large lake’s littoral zone

The study of individual movement patterns and habitat choice is a fundamental step to assess an invasive species’ range extension and to inform possible management options. The spiny-cheek crayfish is an invasive species currently spreading in Europe and also in Lake Constance. This is of concern because the greater Lake Constance area still holds refugial populations of native crayfish that mi...

Gill Na,K-ATPase in the spiny lobster Palinurus elephas and other marine osmoconformers. Adaptiveness of enzymes from osmoconformity to hyperregulation.

Haemolymph inorganic osmolyte changes and Na,K-ATPase activities in trichobranchiate and epipodite tissues were examined in the spiny lobster Palinurus elephas gradually acclimated from seawater (SW; 38 ppt, salinity; 1291 mOsmol/l) down to dilute seawater (DSW; 20 ppt, salinity; 679 mOsmol/l). During acclimation to DSW haemolymph was only transiently hypoosmotic, becoming isosmotic to the medi...
