“…Gnaphalium uliginosum L. is synonymous to Filaginella uliginosa (L.) Opiz. Potamogeton pectinatus, as still used in our Table 3, is assigned the new taxon Stuckenia pectinata (L.) Börner, when following Kaplan (2008).…”

Characterisation of the potamal Danube River and the Delta: connectivity determines indicative macrophyte assemblages

et al. 2011

The complexity of water bodies in the eupotamal river corridor and the main delta channels of the Romanian Danube is exemplified by the macrophyte vegetation. Two hypotheses provided the background for our study: (a) is the macrophyte vegetation of large, permanently connected branches significantly separated from that of the main river channel; (b) is the macrophyte composition of the Danube main stem significantly altered when the river divides into the three large navigable Delta channels. Water bodies considered were two contiguous sections of the main river channel, two large branches remaining from the historical floodplain, and the three main Delta channels. We quantified macrophyte diversity and floristic variation. Our data set was prepared from the MIDCC-project data base, in which macrophyte occurrence, abundance and habitat parameters are stored for contiguous survey units of the whole Danube river corridor. Field survey method followed that of Kohler and the European Standard EN14184. Results confirmed our first hypothesis: permanently connected side branches still support significantly different macrophyte assemblages, making them important indicators of floodplain connectivity. The diversion of the Danube into its three large navigable delta channels significantly alters the macrophyte vegetation from the c. 300 km of main stem up-river, substantially supporting our second hypothesis. Our results largely enhance the knowledge on aquatic plant biodiversity in the eu-potamal Danube, forming a solid base for long-term studies. We also discuss the relevance of our results regarding the ecological, as well as the conservational, quality of rivers and their floodplains.

“…This species occurs in Middle Asia, Pamir Mts, Karakorum Mts and Caucasus Mts at altitudes from about 1800 to 3800 m above sea level [32]. Considering frequent confusion of S. amblyphylla and S. pamirica, presently known distribution of both taxa will have to be revised.…”

“…Revision of the material from Dushanbe (TAD) and Tashkent (TASH) herbaria has shown that a significant part of stored specimens identified as S. pamirica belonged in fact to S. amblyphylla [35]. These species differ, among other traits, in the closure of the leaf sheath and in the blunt or rounded leaf ending in S. amblyphylla [32]. Taking all this into consideration, the community of Stuckenietum amblyphyllae will probably have more compact range in the middle Asian mountainous systems (Pamir-Alai, Kopet-Dag, Tien Shan) and more scattered in Caucasus and Elburs Mts.…”

This paper discusses the floristic structure, distribution and habitat requirements of a new aquatic syntaxon, Stuckenietum amblyphyllae ass. nova. Patches of the Stuckenietum amblyphyllae association occur in the Pamir Alai Mountains in Middle Asia (Tajikistan). The biotope of this community represent high mountain rivers and ponds at the bottom of glacial river valleys situ- ated at elevations between 1900 and 3800 m. Patches of the Stuckenietum amblyphyllae association are characterised by a clear predominance of the typical species, i.e. Stuckenia amblyphylla, which occupies an aerial extent of between near 40 up to 90% of the surface studied. Patches of the community are poor in species, comprising a maximum of five taxa. Among associated species mainly rush, aquatic, meadow and marsh taxa have been noted. The Stuckenietum amblyphyllae community prefers cold, open, alkaline waters with medium flow-rate, ranging in depth from 15 to 75 cm. It is also, but rarely, found in the mountain ponds. Together with the Stuckenia filiformis community it designates in the Pamir Alai Mountains the upper limit of aquatic vegetation.

“…Plants of both P. crispus and P. ochreatus were cultivated in the Experimental Garden at the Institute of Botany, Průhonice, Czech Republic, and tested for phenotypic plasticity in order to better understand the origin of morphological variation (see also Kaplan 2002). In addition, herbarium specimens from around the world were investigated (for the complete list of herbaria see Kaplan 2008 andKaplan 2010). Specimens included in the molecular analyses are summarised in …”

Potamogeton ×jacobsii (Potamogetonaceae) from New South Wales, Australia – the first Potamogeton hybrid from the Southern Hemisphere

Although more than 80 hybrids are documented for Potamogeton in the Northern Hemisphere, the hybrid diversity in the Southern Hemisphere is largely unknown. A taxonomically uncertain Potamogeton plant discovered in New South Wales, Australia, was subjected to detailed morphological investigation and molecular analyses to discover its exact identity. Both approaches resulted in the identification of the Potamogeton specimen as P. crispus × P. ochreatus, which is a previously unrecorded hybrid and is here described as Potamogeton × jacobsii nothosp. nova. Although P. crispus is known to hybridise with many other species, P. ×jacobsii is the first known hybrid involving P. ochreatus.
