Antarctic Research

Buildings were constructed and artefacts left behind on sub-Antarctic Heard Island, associated with Antarctic research expeditions since 1926. Both bryophytes and vascular plants are colonising many parts of the now derelict buildings. On these structures and artefacts, the authors recorded four species of vascular plants out of the 11 that occur on Heard Island and nine species of mosses out of the 37 recorded from Heard Island. The vascular plant species most frequently recorded colonising structures and artefacts was Pringlea antiscorbutica (288 occurrences), with the area colonised varying from 0.3 cm2 to 430.0 cm2. Muelleriella crassifolia was the moss species that was most frequently recorded (14 occurrences), colonising areas from 2.1 cm2 to 12.9 cm2. The highest number of bryophyte species (seven) was recorded on the stone and cement of the ‘water tank.’ Pringlea antiscorbutica, Poa cookii, Azorella selago, Muelleriella crassifolia, Bryum dichotomum, Dicranoweisia brevipes and Schistidium apocarpum are all expected to continue to colonise the ANARE ruins, as well as areas that have become available since building removal and also possibly areas bared by further deglaciation.

Tasmania is the south-eastern island state of Australia. It is geographically isolated and is recognised for both its rich diversity of plant species and high degree of endemism. Although 530 endemic Tasmanian vascular plant species are known, natural products have only been isolated from 27 of these species (~5.1 %), representing 3 classes (Dicotyledonae, Monocotyledonae, and Gymnospermae), 12 families, and 14 genera. Terpenoids, flavonoids, and alkaloids are the major classes of compound that have been isolated from these species. This report provides the first review of the natural products isolated from endemic Tasmanian plant species and covers ~70 years of research in this area.

Abstract The paper presents data on the occurrence and secondary spreading of rare and threatened vascular plant species in railway habitats of Slovakia. We recorded 17 threatened vascular plant species and other 9 species that we considered to be rare in Slovakia. They grew at railway stations, mainly directly in the rail yard and also at the platforms or other similar facilities. Records of further 39 species were excerpted from literature sources. More native thermophilous species were represented among the recorded species as railway substrates provide suitable conditions for their growth. Also some archaeophytic segetal species were found quite frequent in the studied biotopes due to spreading of their seeds together with cereals transported by trains. Various habitats of railway transport facilities often provide suitable conditions for the secondary occurrence and further spreading not only of synanthropic or adventive, but also of rare and threatened plant species.

Vascular Plant Species

The paper presents the occurrence of vascular plant species in the southern part of the Pilzno commune based on monographic studies from the area of Ciężkowice and Strzyżów Foothills (Western Carpathians). The study contains a list of plant species, both native and of alien origin. For each species its habitat and sites in the ATPOL network were given.

The flora at Tan Trao historical site, Tuyen Quang province is quite rich and varied. Initially, there were 726 species, 462 genera, 137 families, belonging to 6 vascular plant species. Among them, Magnoliophyta has the largest number of 669 species (accounting for 92.15%), 427 (accounting for 92.42%) and 115 families (accounting for 83.94%). Followed by the Polypodiophyta with 39 species (5.37%), 25 genera (5.41%), 13 families (9.49%). Psilotophyta, Lycopodiophyta, Equisetophyta, Pinophyta are the rest. The Magnoliophyta is the most diversified, with 5.82 species per family and 3.71 families per family. The survival spectrum of the Tan Trao historical flora was determined as SB = 73.55 Ph + 3.17 Ch + 9.78 He + 8.40 Cr + 5.10 Th. For the value of use, medicinal plants have the most abundant species with 470 species, timber trees have 188 species, 142 species are eatable, 99 species are ornamental plants, 64 species are for animal feed,  50 species are giving attar , 28 species  are fibre plants,11 species are used for handicrafts, 5 species of dyes, and the lowest of 3 species for sap plants.
