SUMMARY The phenotype of an organism is determined by the genes, environment and stochastic developmental events. Although recognized as a basic biological principle influencing life history, susceptibility to diseases, probably evolution, variation (DV) has been only poorly investigated due lack suitable model organism. This obstacle could be overcome using recently detected, robust highly fecund parthenogenetic marbled crayfish experimental animal. Batch-mates this clonal crayfish, which...
Recently, we briefly reported on the first case of parthenogenesis in decapod Crustacea which was found Marmorkrebs or marbled crayfish, a cambarid species unknown geographic origin and identity. Curiously, this animal is known only from aquarium populations, where it explosively propagates. By means light electron microscopic techniques have now investigated reproductive components using more than 100 specimens ranging hatchling to repeatedly spawned adult. Additionally, documented its...
ABSTRACT The parthenogenetic all-female marbled crayfish is a novel research model and potent invader of freshwater ecosystems. It triploid descendant the sexually reproducing slough crayfish, Procambarus fallax, but its taxonomic status has remained unsettled. By cross-breeding experiments parentage analysis we show here that P. fallax are reproductively separated. Both copulate readily, suggesting reproductive barrier set at cytogenetic rather than behavioural level. Analysis complete...
Abstract Model organisms have contributed significantly to the understanding of basic biological phenomena. Suitable animal models are at hand for some research disciplines like genetics, development and cell biology but still sought after others epigenetics. Research last years has revealed that marbled crayfish (Marmorkrebs), which was discovered in mid‐1990s, meets researchers' demands a vigorous, genetically identical eurytopic laboratory model very well. Its most prominent advantages...
The hepatopancreas of decapod crustaceans is used as an example to illustrate the range cytopathologies, detoxification mechanisms, and immune responses that environmental toxicants pathogens can induce in a single organ. central metabolic organ decapods consists hundreds blindly-ending tubules intertubular spaces. tubular epithelium contains 5 structurally functionally different cell types, interstitium haemolymph, haemocytes, connective tissue, fixed phagocytes. Some physiological...
Abstract Prolonged brood care is one of the evolutionary clues for successful colonization freshwater habitats by crayfish (Astacida). By means macrophotography, light microscopy, and scanning electron microscopy we investigated all phases in crayfish, with particular emphasis on morphological structures involved. We selected recently discovered parthenogenetic marbled (species identity not yet known) as a model organism due to its fast reproduction high resistance handling stress. In order...
The late embryonic and early post-embryonic life period of freshwater crayfish, which is the main time organogenesis, poorly investigated because protective brooding behavior crayfish mothers. A combination in vitro culture, behavioral observations, microscopic investigations organs involved hatching, attachment, exploration environment, searching processing food yielded deeper insights this important life. Experiments were performed with robust parthenogenetic marbled crayfish. following...
