Hulina, N.: Rare, endangered or vulnerable plants and neophytes in a drainage system in Croatia, Nat. Croat., Vol. 7, No. 4., 279–289, 1998, Zagreb In an extensive network of field and lateral drain channels, in the area of Turopolje and ^rnec Polje, seven locally and generally rare, endangered or vulnerable plants were noted. These are: Riccia fluitans L., Marsilea quadrifolia L., Utricularia ...
During an investigation on pteridophytes (ferns) of Guilan province (N Iran), 402 specimens were studied. Of these, 44 species, under 21 genera, belonging to 13 families, were identified. Based on the approved instruction given by the "International Union for the Conservation of Nature and Natural Resources (IUCN)", after performing the filtering stage, 17 species were identified as endangered...
Aim Whether richness patterns and determinants are consistent between common and rare species remains controversial, and the answer is fundamental for the conservation of species in vulnerable habitats. Although effects of climate and geological history on species richness have been widely explored, their relative contribution among common and rare species is poorly understood. Here, using a va...
biglar permo-triassic bauxite deposit is located in ~15 km northwest of abgarm, southwest of ghazvin province, west of central iran. it consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of ruteh (permian) and elika (triassic) carbonate formations. petrographically, the bauxite ores exhibit collomorphic-fluidal, pseudo-breccia, pseudo-porphyritic, panidio-morphic-...
background recent studies suggest that rare codon clusters are functionally important for protein activity. methods here, for the first time we analyzed and reported rare codon clusters in hepatitis c virus (hcv) genome and then identified the location of these rare codon clusters in the structure of hcv protein. this analysis was performed using the sherlocc program that detects statistically ...
UNLABELLED • PREMISE OF THE STUDY Mountainous regions support high plant productivity, diversity, and endemism, yet are highly vulnerable to climate change. Historical records and model predictions show increasing temperatures across high elevation regions including the Southern Rocky Mountains, which can have a strong influence on the performance and distribution of montane plant species. Ra...
