Extension of typha laxmannii new record range in the south of the ukrainian ssr ussr in relation to construction of large canals


, : Extension of typha laxmannii new record range in the south of the ukrainian ssr ussr in relation to construction of large canals. Ukrayins'kyi Botanichnyi Zhurnal 34(6): 612-616

T. laxmannii Lepech. occurred previously only on the coastal zone of the Black Sea [USSR]. Data was preserved on its advance northward in connection with canal construction. The species was found before along the Dnieper reservoir cascade, the Kremenchung one being included. It is now found along the large irrigation canals in the filtration zone. Five groups of procenoses with a predominance of T. laxmannii are distinguished, with brief characteristics and distribution type dependent on soil moisture and salinity content. Two definite ecological series of communities with the presence of T. laxmannii are presented. Species advance beyond the former area of distribution provides evidence for noticeable changes in ecological conditions resulting from canal construction. The index of biotic dispersion (according to Koch) for T. laxmannii communities is compared with that for steady cenoses of real bogs.
