POLLINATION BIOLOGY OF GNETUM (GNETACEAE) IN A LOWLAND MIXED DIPTEROCARP FOREST IN SARAWAK
The prevalence of entomophily inthe Gnetales (i.e., Gnetum, Ephedra, and Welwitschia) may suggest that unspecialized insect pollination originated before the divergence between the G netales and angiosperms.

It is confirmed that at least three Glochidion species are pollinated only by their respective seed-parasitic moth species, which could be distinguished by genitalic morphology and mitochondrial DNA sequences, and suggested that speciation based on the highly specialized GlochIDion stylar structure and moth oviposition behavior have promoted species diversification in Glochids and its pollinators.

Nocturnal flying insects were collected monthly for 13 months using ultra violet light-traps set at various vertical levels in a weakly-seasonal, tropical lowland dipterocarp forest in Sarawak, Malaysia to detect non-random, seasonal trends of insect abundance.
Preparation and Mechanical Properties of Polypropylene−Clay Hybrids

Polypropylene (PP)−clay hybrids (PPCH) have been prepared by simple melt-mixing of three components, i.e., PP, maleic anhydride modified polypropylene oligomers (PP-MA), and clays intercalated with…

It is concluded that gaps are an exceptionally reliable source of phylogenetic information that can be used to corroborate and refine phylogenies hypothesized by base substitutions, at least at lower taxonomic levels.
Nonuniform concerted evolution and chloroplast capture: heterogeneity of observed introgression patterns in three molecular data partition phylogenies of Asian Mitella (saxifragaceae).
This finding indicates that the use of multiple molecular tools has the potential to reveal detailed organismal evolution processes involving interspecific hybridization, as an individual locus varies greatly in its potential to introgress between species.
Adaptive radiation of gobies in the interstitial habitats of gravel beaches accompanied by body elongation and excessive vertebral segmentation

This is the first study to document the adaptation to interstitial habitats by a vertebrate and suggest that microhabitat partitioning has been an important mechanism facilitating speciation in these fishes.
Synthesis of polypropylene oligomer—clay intercalation compounds
The synthesis of polypropylene (PP) oligomer—clay intercalation compounds was studied by using three kinds of PP oligomers and organophylic clay. PP oligomers were two types of…
Repeated independent evolution of obligate pollination mutualism in the Phyllantheae–Epicephala association
It is shown that, in Phyllantheae, specialization to pollination by Epicephala moths evolved at least five times, involving more than 500 Phyllalae species in this obligate association.
