ULTIMATE COSTS OF SPOROPHYTE PRODUCTION IN THE CLONAL MOSS HYLOCOMIUM SPLENDENS

A New Biflavone and Further Flavonoids from the Moss Hylocomium splendens

Whereas many reports now exist on flavonoids of liverworts only few publications are concerned with the flavonoid pattern of mosses [1—5]. The detection of an apigenin 7-O-rhamnoglucoside from H yloco­ mium splendens was reported [6]. Screening chroma­ tograms of samples of H. splendens collected at about 20 different localities showed however a much richer flavonoid pattern as supposed previou...

Clonal structure and genet-level sex ratios suggest different roles of vegetative and sexual reproduction in the clonal moss Hylocomium splendens

Critical remarks on the use of terrestrial moss (Hylocomium splendens and Pleurozium schreberi) for monitoring of airborne pollution.

Duplicate samples of the two terrestrial moss species Hylocomium splendens and Pleurozium schreberi, which are widely used to monitor airborne heavy metal pollution, have been collected from eight catchments spread over a 1,500,000 km2 area in northern Europe. These were analysed for a total of 38 elements by inductively coupled plasma-mass spectrometry, inductively coupled plasma-atomic emissi...

Testate amoebae (Protista) communities in Hylocomium splendens (Hedw.) B.S.G. (Bryophyta): relationships with altitude, and moss elemental chemistry.

We studied the testate amoebae in the moss Hylocomium splendens along an altitudinal gradient from 1000 to 2200 m asl. in the south-eastern Alps of Italy in relation to micro- and macro-nutrient content of moss plants. Three mountainous areas were chosen, two of them characterised by calcareous bedrock, the third by siliceous bedrock. A total of 25 testate amoebae taxa were recorded, with a mea...

Physiological responses of bryophytes Thuidium tamariscinum and Hylocomium splendens to increased nitrogen deposition.

BACKGROUND AND AIMS Increased levels of nitrogen (N) deposition lead to enhanced N contents and reduced productivity of many bryophyte species. This study aimed at elucidating the mechanisms by which enhanced N uptake may cause growth reduction of bryophytes, focusing on the effects of N addition on carbon (C) metabolism of bryophytes. METHODS Plantlets of Thuidium tamariscinum and Hylocomium...
