The major gut bacteria of the worker caste of nine species of Australian termites, belonging to four families, were isolated and identified to generic level. All species were either facultative anaerobes or strict aerobes. A correlation appears to exist between the major gut bacterium and the family to which the termite belongs. The major bacterium from the two lowest termites, Mastotermes darw...

A revision of the genus Ateralphus Restello, Iannuzzi & Marinoni, 2001, based on the detailed study of the morphology of the type-species and on the external morphology and terminalia of the others species is presented. The genus and species are redescribed and three new species are described. The genus is composed of nine species: A. dejeani (Lane, 1973), A. javariensis (Lane, 1965), A. lacteu...

The nemerteans belong to a phylum of coelomate worms that display a highly conserved pattern of cell divisions referred to as spiral cleavage. It has recently been shown that the fates of the four embryonic cell quadrants in two species of nemerteans are not homologous to those in other spiralian embryos, such as the annelids and molluscs (Henry, J. Q. and Martindale, M. Q. (1994a) Develop. Gen...

Coptotermes travians (Haviland) is one of the most important subterranean termite pest species attacking urban buildings and structures in Malaysia. Two colonies of C. travians infesting residential premises (Colony A & B), and another one in a natural habitat (Colony C) were characterized. Foraging territories ranged between 125 384 m2, with maximum foraging distances of 17 32 m per colony. At...

Mitochondrial small subunit ribosomal DNAs of Cerrena unicolor and Trametes consors were sequenced and compared with those of known mushroom taxa. Trametes consors is a species recently transferred from Irpex, and Cerrena is a genus closely related to Trametes. The present phylogenetic tree showed that Cerrena unicolor and Trametes consors clustered together and made an independent lineage from...

The positions of the disulfide bonds in Cerebratulus lacteus toxin B-IV were investigated by hydrolysis of the unreduced protein with a variety of proteases. The resulting peptides were purified by gel filtration, ion exchange chromatography, and preparative paper electrophoresis and chromatography. Determination of the amino acid compositions of the cystine-containing peptides purified demonst...

Plastic waste has become a hot topic in sustainability and conservation, helped part by popular documentaries which have highlighted the issue to general public. Much of current literature focuses on effect microplastics marine environment, with very little information macroplastic interactions or terrestrial environment. In this report, management digit constriction due debris Verreaux’s eagle...
