Molecular phylogeny and biogeography of the nasute termite genus Nasutitermes (Isoptera: Termitidae) in the pacific tropics.
The phylogenetic relationships among 17 Nasutitermes species from the Pacific tropics were inferred from sequences of mitochondrial cytochrome oxidase II and 16S ribosomal RNA genes, showing almost the same topology and in good agreement with reconstructions based on morphological or behavioral characters.

Genetic variation of symbiotic fungi cultivated by the macrotermitine termite Odontotermes formosanus (Isoptera: Termitidae) in the Ryukyu Archipelago
It is demonstrated that horizontal transmission of symbiotic fungi among termite colonies occurred during the evolutionary history of this symbiosis, and that fungus combs are probably a monoculture within a single termite colony. Expand
Molecular phylogeny of the Rhinotermitidae
A number of disagreements were found between the molecular tree and traditional classifications of genera within subfamilies among the termite family Rhinotermitidae, however relationships were not well defined. Expand
Caste‐specific cytochrome P450 in the damp‐wood termite Hodotermopsis sjostedti (Isoptera, Termopsidae)
In the damp‐wood termite Hodotermopsis sjostedti, differentiation into the soldier caste is induced by using juvenile hormone analogue treatment and specific gene expression appeared during the hormonal response and triggered caste differentiation, using fluorescent differential display. Expand
Divergence times in the termite genus Macrotermes (Isoptera: Termitidae).
Sequences of the mitochondrial COII gene and Bayesian dating are used to investigate the time frame of the evolution of Macrotermes, an important genus of fungus-growing termites, and it is found that the genus Macro termes consists of at least 6 distantly related clades. Expand
The evolution of soil-burrowing cockroaches (Blattaria: Blaberidae) from wood-burrowing ancestors following an invasion of the latter from Asia into Australia
Soil–burrowing cockroaches appear to have evolved from a lineage of wood burrowers that invaded Australia from the north some time after the merging of the Asian and Australian tectonic plates ca. Expand
Changes in Cretaceous ammonoid diversity and marine environments of the Japanese Islands
This study surveys 902 species of Cretaceous ammonoids in Japan, and identifies species diversity changes during 29 Japanese Cretaceous substages. The species diversity, fluctuates between the peakExpand
