Di Indonesia terdapat kurang lebih 506 jenis meranti, yang tersebar di Sumatera, Kalimantan, dan Maluku. Populasi meranti Maluku dijumpai Pulau Taliabu, Mangole, Sanana, Buru Seram. Pulau-pulau ini terletak paling Timur adalah Sebaran Seram Kabupaten Bagian Barat (Kecamatan Inamosol) Tengah Tehoru). Tujuan penelitian untuk mengetahui potensi populasi, karakteristik morfologi pola penyebaran mer...

Armophorean ciliates constitute an important component of microeukaryotic community in anaerobic or hypoxic environments. Yet, their diversity remains poorly known due to under-sampling the scarcity knowledge. In this study, three metopid ciliates, i.e., Metopus paraes sp. n., spiculatus and parapellitus collected from coastal sediments Qingdao Rizhao, China, were investigated using live observ...

Representatives of the genus Hedera L. have been cultivated in Nikitsky Botanical Gardens over two centuries. The inventory collection has revealed thirty five species, cultivars, and forms, including four relics cultivation – H. helix 'Angularis', 'Rugosa', 'Cavendishii', hibernica 'Scutifolia'. presence three thirty-two cultivars forms belonging to which species varieties reached generative s...

microorganisms are important components of soil. some soil filamentous fungi such aspenicilium produce many bioactive small molecules, or secondary metabolites, that range frombeneficial bioactive compounds to harmful toxins. in this study, the metabolites of threepenicillium species (p. goditanum, p. moldavicum and p. corylophilum) were extracted byadding ethyl acetate to liquid cultures. the ...

let $g$ be a finite $p$-soluble group‎, ‎and $p$ a sylow $p$-subgroup of $g$‎. ‎it is proved‎ ‎that if all elements of $p$ of order $p$ (or of order ${}leq 4$ for $p=2$) are‎ ‎contained in the $k$-th term of the upper central series of $p$‎, ‎then the $p$-length of‎ ‎$g$ is at most $2m+1$‎, ‎where $m$ is the greatest integer such that‎ ‎$p^m-p^{m-1}leq k$‎, ‎and the exponent of the image of $p$...

for a symmetric group $g:=sym(n)$ and a conjugacy class $mathcal{x}$ of involutions in $g$, it is known that if the class of involutions does not have a unique fixed point, then - with a few small exceptions - given two elements $a,x in mathcal{x}$, either $angbrac{a,x}$ is isomorphic to the dihedral group $d_{8}$, or there is a further element $y in mathcal{x}$ such that $angbrac{a,y} cong ang...
