Molecular Phylogeny of Dipetrocarpaceae in Southeast Asia Based on Nucleotide Sequences ofmatK,trnL Intron, andtrnL-trnF Intergenic Spacer Region in Chloroplast DNA
Tadashi Kajita,Koichi Kamiya,Kaho Nakamura,Hidenori Tachida,Ratnam Wickneswari,Yoshihiko Tsumura,Hiroshi Yoshimaru,Tsuneyuki Yamazaki +7 more
TL;DR: This result suggests that the chromosome number changed from x = 11 to x = 7 after Dipterocarpus branched in the latter cluster, and other evolutionary changes of morphological characters are also discussed.

Phylogenetic relationships of Diploxylon pines (subgenus Pinus) based on plastid sequence data
TL;DR: The plastid DNA sequences of rbcL, matK, the trnV intron, and the rpl20‐rps18 spacer in 38 species of subgenus Pinus, representing all recognized subsections, were analyzed and relationships with maximum parsimony, neighbor joining, and maximum likelihood algorithms were assessed.

Phylogeny of PgiC gene in Shorea and its closely related genera (Dipterocarpaceae), the dominant trees in Southeast Asian tropical rain forests
TL;DR: Partial sequences of the PgiC gene from species of Shorea, Hopea, Neobalanocarpus, and Parashorea were determined to elucidate phylogenetic relationships among the species of these genera and generated a gene tree with better resolution than previous cpDNA trees.

Monitoring levels of cyanobacterial blooms using the visual cyanobacteria index (VCI) and floating algae index (FAI)
Yoichi Oyama,Takehiko Fukushima,Bunkei Matsushita,Hana Matsuzaki,Koichi Kamiya,Hisao Kobinata +5 more
TL;DR: Application of the thresholds for VCI classifications to three Landsat/ETM+ images showed that the volume of cyanobacterial blooms can be effectively classified into the six VCI levels.

TL;DR: Methods for extracting and analyzing DNA from wood products, such as veneers and sawn timbers made from dipterocarps, in order to identify the species from which they originated, and a chloroplast DNA database for classifying Shorea species.
