Abstract The study about the diversity and structure of treelet vegetation in three slope areas on mountainous forest mount Bawakaraeng, Regency Gowa, Province South Sulawesi had been done. There were 17 species treelets throughout area, from 13 families 16 genera. Asteraceae family has highest number with 3 species, followed by Fabaceae Solanaceae which each 2 species. Pteridium aquilinum , Ch...

One of the drawbacks of typical dye-sensitized solar cells (DSCs) is their high cost and the high electrical resistance of the transparent conducting substrate. In conventional sandwich-type DSCs, only one of the FTO substrates can be replaced by a metal substrate. We investigated an all-metal-electrode single-sided DSC in which interpenetrated bracken-like Cr electrodes were created using phot...

Isolated oceanic islands are characterized by patterns of biological diversity different from that on nearby continental mainlands. Isolation can provide the opportunity for evolutionary divergence, but also set the stage for hybridization between related taxa arriving from different sources. Ferns disperse by haploid spores, which are produced in large numbers and can travel long distances in ...
