Cephalanthera damasonium (Mill.) Druce is rare and protected species. It is also placed in the "red list" of vascular plants threatened in Poland (V category) and of the Małopolska Upland (VU category). The new locality of C. damasonium was found in 2014 on remnants of former iron-ore mining in the Suchedniów Forest Inspectorate (Małopolska Upland, ATPOL grid square EE5502) (Fig. 1). A population of the species counted 30 individuals (10 specimens in generative and 20 in vegetative state) which grew in phytocoenosis of the Querco-Fagetea class. To protect the new locality of C. damasonium and also an old extraction site (which is interesting from environmental viewpoint) - the part of forest compartment with fertile beech forest community should be excluded from forest management.

The paper is a review of the literature, including the authors'own studies, concerning the thermal stability, flammability and mechanical properties of elastomeric nanocomposites containing montmorillonite clay or halloysite nanotubes. The thermal decomposition of elastomeric nanocomposites was investigated, taking into account the type and quantity of the nanoadditive, its barrier properties, the structure of carbon layer as well as the interactions between the nano-additive and reactive groups in the elastomer.

The paper is a continuation of literature review on thermal stability, flammability and mechanical properties of elastomeric nanocomposites containing montmorillonite clay, halloysite nanotubes, attapulgite as well as carbon nanotubes and nanofibres. The mechanism of degradation and thermal decomposition of elastomeric nanocomposites was examined from the point of view of: the type and amount of nanoaddititve, structure formed during the combustion of carbon layer, barrier properties of the nanoparticles as well as the interactions between a specific additive and reactive groups in the elastomer.

This paper is the first part of cycle of articles concerning information about protected, threatened and rare vascular plants species growing in forest communities which emerging on old iron-ore extraction sites situated in the northern outskirts of the ͆więtokrzyskie Mountains (the Małopolska Upland). The paper gives localities of 41 taxa recorded in years 2010-2013:12 mountain species, 15 protected species and 19 threatened species. The last taxa are the rare plants in the region. All of the taxa represent native element in the Polish flora. Source


This paper contains information about protected and threatened vascular plant species of the Garb Gielniowski Hummock. In flora of the mesoregion there are: 80 protected species (including 65 strictly protected species and 15 partially protected species) and 158 threatened species (therein 154 species are placed on the red list of the Wyżyna Małopolska Upland and 39 species are threatened in Poland). Original local red list of vascular plant species of the Garb Gielniowski Hummock contains 133 species in seven individual threat categories: 18 species extinct in the mesoregion (RE category); 25 critically endangered species (CR category); 19 endangered species (EN category); 44 vulnerable species (VU category); 15 near threatened species (NT category); 10 least concern species (LC category); 2 data deficient species (DD category). Share of these species in habitat groups shows domination of forest and shrubs species (46 species). Quite numerous are also peat-bog species (18 species), meadow species (17 species) and species occur on waterside and muddy sites (14 species) - these habitat groups are the most typical for all native flora of mesoregion.
