Ecological and phylogenetic aspects of the spring diet of three palaearctic species of swans

BMC Ecology and Evolution
The quality of swans' nutrition at spring migration stopovers is important for their successful breeding. It is of great interest to study the differences in nutrition of different swan species when sharing the same habitat.

Morphology And Anatomy Of Nuphar Lutea (L.) Smith. Terrestrial, Floating And Submersed Leaves

, 2012
The anatomy of the geterophyllous aquatic plant Nuphar lutea terrestrial, floating and submersed leaves was investigated. The anatomy of floating leaves is shown to be different from rosette leaves in the following: absence of stomata, cuticula, asterosclereids, differentiated parenchyma, reduce intercellular volume and leaf width.

Sulphoxides of thiobinupharidine thiohemiaminals from Nuphar lutea

Phytochemistry, 1986
Abstract From the rhizomes of Nuphar lutea four new alkaloids were isolated. Their structures were established as syn-6-hydroxythiobinupharidine sulphoxide, syn-6′-hydroxythiobinupharidine sulphoxide, syn-6,6′-dihydroxy thiobinupharidine sulphoxide and anti-thiobinupharidine sulphoxide.

Distinct diversity patterns of Planctomycetes associated with the freshwater macrophyte Nuphar lutea (L.) Smith

Antonie Van Leeuwenhoek, 2017
Members of the phylum Planctomycetes were originally described as freshwater bacteria. Most recent studies, however, address planctomycete diversity in other environments colonized by these microorganisms, including marine and terrestrial ecosystems.

Genetic diversity of Nuphar lutea in Lithuanian river populations

Aquatic Botany, 2020
Abstract Currently, in Europe, increasing attention is being paid to the genetic diversity of aquatic macrophytes. Insufficient information exists about the river plants of the Baltic states. Our study aimed to evaluate the genetic diversity of Nuphar lutea individuals growing in Lithuanian watercourses. Eighteen populations were studied in the river

Resorcinol in exudates ofNuphar lutea

Journal of Chemical Ecology, 1996
Resorcinol (1,3-dihydroxybenzene) was identified as one of the major constituents of the exudate ofNuphar lutea seedlings, which were raised from seeds and cultivated under axenic conditions. The compound is released from the plants in considerable amounts (up to 15 nmol/seedling/day).
