This article describes 12 species of rare and redlisted crustose lichens which are more or less common in the coastal pine forests in the southwestern part of Norway, normally referred to as boreonemoral rainforests due to their occurrence in the boreonemoral climatic zone. Many locations are relatively rich in deciduous trees where these specified...

The earth tongue Geoglossum hakelieri is a very rare species only known from Norway and Sweden, first described in 1967 by Hakelier and representing only three finds in Norway (Bendiksen et. al 1998, Artskart 2024), and it has not been found since 1993. In the first week of September 2024 a workshop on grassland fungi was held in Tjøtta, Alstadhaug...

Baldellia repens is a very rare species in Norway, restricted to the south-western part of the country. These populations represent the species' northern global distribution limit. The species is known from four individual lakes in Norway, most of which have a relatively high pH. In addition, the plant was, during the early 1960s, introduced to a s...

The semi natural grassland described in this paper, Hovaneset in Stord municipality, South- Western Norway, has been examined for grass- land fungi for 20 years, from 2003 until today (2022). This has resulted in the discovery of 92 different species after a total of 180 visits to the locality. Change in the frequency of survey to approximately a w...

Hemileucoglossum pusillum was first described from Slovakia in 2017 and is also known from Spain. The first record in Norway was collected as early as 2010 and is later found almost every year since on the same spot. At that time, little was done concerning revision of the genera in Geoglossaceae, and the fungus has remained undetermined until toda...

Asplenium scolopendrium is a very rare fern in Norway, where it has its northernmost global finds. It mainly grows along the western coast in deep crevices, often beneath protruding rocks. The populations are normally relatively small, and the different localities are often situated far apart. It is therefore legitimate to speculate if many of the...

The flavonoid content in leaves of Zostera marina and the endangered Zostera noltii, including mono- and disulphated flavonoids, from different sample localities were characterized. Seasonal variation of both individual and total flavonoid, as well as rosmarinic acid concentration were revealed. Minor amounts of luteolin 7-(6″-malonyl)glucoside (6)...

This report is an attempt to provide an overview of all red-listed species known from the municipalities of Stord and Fitjar, based on the last Norwegian Red List of 2015 and survey made by the author. In addition, some general information about the nature of South-Western Norway and rare and red-listed habitats found in the two municipalities, are...

Cephalanthera longifolia is redlisted as near threatened (NT) on the Norwegian redlist (2015), and is among one of 13 protected orchids in Norway. In South-Western Norway only a few localities with only a few plants of C. longifolia were known until 2014 when a new locality were discovered in the municipality of Tysnes. Here the plants were growing...

Dwarf eelgrass Zostera noltei Hornem. is a rare plant in Norway, and is on the Norwegian red list (2015) considered to be endangered (EN). It occurs today only at 13 known localities in Norway, while 10 occurrences seems to have become extinct the last 50 years (Lundberg 2013). South-Western Norway had until recent years four of the most northerly...

The report describes new discoveries of different plants and fungi in Sunnhordland and Nord Rogaland, Western Norway in 2013-14. A total of 14 localities in the municipalities of Stord, Tysnes, Bømlo and Rennesoy are described, where 11 are new and three are examined earlier. It resulted in 70 new discoveries of 43 different species listed on the N...

From 2007 and till today several new locations of Isolepis setacea have been found in Sunnhordland. One reason is that there has been an intensive investigation of cultural landscapes the last years. In 2013 the biggest known occurrence of Isolepis setacea in Stord was destroyed by covering it with huge amounts of stones and gravel by a constructio...

Hovaneset is located in the municipality of Stord and are one of the richest localities for grassland fungi in the southwestern part of Norway (Sunnhordland). All together 71 different grassland fungi are known from the area including 32 species which are found on the Norwegian red list. The area has been investigated several times the last 11 year...

The cultural landscape in the western part of the island of Spyssøya in the municipality of Bømlo is unique in containing a large number of red-listed vascular plants, oceanic lichens and mosses, and grassland fungi. The locality is a mosaic of steep hills with deciduous forests surrounding patches of old grasslands and steep vertical rocks towards...

Systematic surveys of macromycetes in old grasslands in West Norway, Sunnhordland have been performed during the last 10 years. In this paper the earthtongues (Geoglossaceae) are presented and their ecology is discussed. Their distribution in Norway is briefly commented on. Before 1999 only eight species of earthtongues were known from the area and...

The species dwarf eelgrass Zostera noltei has been recorded from 18 localities in Norway. By 2006 the number of localities had been reduced to eight, with the species having either disappeared or with unknown status at the remaining localities. Three of the eight known localities are situated in the municipality of Stord on the western coast of Nor...

Natural grasslands are environments in strongdecline all over Europe. Many grassland fungi are sensitive both to the application of artificial fertilizers and reduced grazing. Many grassland species are therefore listed on the national red-lists of different countries. In September 2008, during two days of fieldwork in the municipality of Karmøy in...

The research program Education, Curricula & Technology is supported by the Norwegian Research Council. The research group consists of researchers from different disciplines at Stord/Haugesund University College as well as international researchers, PhD and master students in ICT and learning. The aim is to study the complex relationship between ICT...

Eit utval av naturtypar i Fitjar og Stord kommunar er kartlagt og verdisett i samsvar med DN-handbok 13 ”Kartlegging av naturtyper. Verdisetting av biologisk mangfold”. Rapporten presenterer resultata frå dette arbeidet, som i hovudsak er basert på eige feltarbeid frå 2003 til 2008, samt redigering av eksisterande data. I Fitjar og Stord er det reg...

Several red-listed plants growing in or on freshwater shores have long been known to grow in the municipality of Stord. Stord is an island in the county of Hordaland in the western part of Norway. During the past 5 years, data from the National Database of Vascular Plants has been checked by field observations in four different lakes. Cladium maris...

The properties of a DNA-repair endonuclease isolated from mouse plasmacytoma cells have been further studied. It acted on ultraviolet-light-irradiated supercoiled DNA, and the requirement for a supercoiled substrate was absolute at ultraviolet light doses below 1.5 kJ m-2. At higher doses relaxed DNA could also serve as a substrate, but the activit...

A new procedure has been developed for the isolation of the chromosome complex, termed chromatin, from Escherichia coli. The bacteria were subjected to low ionic strength and T4 lysozyme, followed by detergent treatment analogous to that employed for the isolation of eukaryotic chromosomes. The chromatin was an insoluble viscous material which cont...

Sendai virus is haemolytic against erythrocytes from different species. Pre-treatment of Sendai virus with antibody and complement (C) enhances the haemolytic activity of the virus. This property was used to examine the pathway by which C is activated by Sendai virus antigen-antibody complexes. Antibody against the keratosulphate-like host antigen...

Sendai virus is haemolytic against erythrocytes from various species. Pretreatment of the virus with antibody and complement (C) resulted in a sixfold increase in the haemolysis. The viral haemolysin (HL) could be inactivated by heating the virus at 37 degrees C for 5 h. HL-inactivated virus became haemolytic again when pre-treated with antibody an...
