%0 Journal Article %T MASTER AND PUPIL ¨C DR. J¨¢N BRTEK AND I %A Hidetoshi NAGANAWA %J Lakes reservoirs and ponds %D 2008 %I Romanian Limnogeographical Association %X Large branchiopod studies were born and bred in the Danube basin in some Eastern European countries (the former Czechoslovakia, Hungary, and Romania). The leading expert was the late Dr. J¨¢n Brtek in Slovakia. Large branchiopods are usually habitants of such temporary lakes and ponds as inland bodies of fresh, mineralized, salt water or hypersaline. This article has two distinct goals: (1) to review the history of large branchiopod studies and (2) to draw attention to some of the scientific interest and value of ephemeral aquatic habitats, introducing my reminiscences of Dr. Brtek. %K Crustacea %K large branchiopods %K living fossil %K Anostraca %K Spinicaudata %K temporary ponds %K underground mineral waters %K Mongolia %U http://www.limnology.ro/Lakes/2008/20081218.pdf
