Soothing Shrimp Posted June 12, 2014 Report Share Posted June 12, 2014 Found a neat scientific paper written about comparative study between Marmokrebs and Procambarus fallax. In short, the research concludes that Marmorkrebs is actually a form of Procambarus fallax, and NOT alleni or a cross. This form of Procambarus fallax obviously has the ability of parthenogenesis- and although it exists in aquariums and said to be found in the wild of Japan, Germany, Italy, Madagascar, and the Netherlands- a natural population of them are currently unknown. Here's the paper if anyone wants to delve that far: http://www.ctoz.nl/cgi/t/text/text-idx?c=ctz;sid=85b8cb4e58ea2be46fd44ad7733e3272;rgn=main;idno=m7903a03;view=text So, although the paper does not mention a correct way of labeling them, I suppose it could be something like: Procambarus fallax var.

chibikaie Posted June 12, 2014 Report Share Posted June 12, 2014 http://faculty.utpa.edu/zfaulkes/marmorkrebs/ Procambarus fallax f. virginalis is cited as the current scientific name on that site. Author is legit as far as I can tell; as I research them, he pops up on message boards that lead me back to his page. Quote Link to comment Share on other sites More sharing options...

zfaulkes Posted June 12, 2014 Report Share Posted June 12, 2014 It's still possible that Marmorkrebs is a hybrid of some sort. The Martin et al. (2010) paper uses only mitochondrial DNA for the test, which you only get from the mother. Nuclear DNA is inherited from both parents, and might tell a more complicated story. Asexual species often turn out to have some sort of hybrid origin. Zen Faulkes Biology, UTPA Apparently legit Quote Link to comment Share on other sites More sharing options...
