Chemotaxis Toward Amino Acids in Escherichia coli
TLDR
Two essentially nonoxidizable amino acid analogues, alpha-aminoisobutyrate and alpha-methylaspartate are shown to be attractants for E. coli, demonstrating that extensive metabolism of attractants is not required for amino acid taxis. Expand
The Range of Attractant Concentrations for Bacterial Chemotaxis and the Threshold and Size of Response over This Range
TLDR
Although the data are inadequate, it appears that the Weber law may be observed over a wide range of concentrations for some attractants but not for others. Expand
Diversity and abundance of some ground-dwelling invertebrates in plantation vs. native forests in Tasmania, Australia
TLDR
Invertebrate conservation may be assisted by specific forestry operations, including windrowing, mound ploughing, and leaving waste prunings and thinnings to rot, reducing the risk of local extinctions. Expand
Escherichia coli mutants defective in chemotaxis toward specific chemicals.
TLDR
Mutants of Escherichia coli K12 have been found which fail to carry out chemotaxis toward certain chemicals only, and there is a correlation between the galactoseChemotaxis defect and a defect in galactOSE uptake, perhaps indicating a common component for chemot axis and uptake systems. Expand
Relative efficiency of pitfall trapping and hand-collecting from plots for sampling of millipedes
TLDR
Millipedes were sampled by hand-collecting from plots and by pitfall trapping at three forest sites in central Tasmania to provide more accurate data on species diversity and relative abundance for a range of litter invertebrates. Expand
New species of Prosopodesmus Silvestri, 1910 (Diplopoda, Polydesmida, Haplodesmidae) from Queensland, Australia
TLDR
The hothouse species Prosopodesmus panporus Blower & Rundle, 1980 is recorded from rainforest on Queensland’s Cape York Peninsula, where it is likely to be native. Expand
Dirt-encrusted and dragon millipedes (Diplopoda: Polydesmida: Paradoxosomatidae) from Queensland, Australia
TLDR
Three unusual new Paradoxosomatidae are described from tropical north Queensland, which closely resembles the dragon millipedes Desmoxytes of southeast Asia, but differs in gonopod details. Expand
A specialist’s audit of aggregated occurrence records
TLDR
Occurrence records for named, native Australian millipedes from the Global Biodiversity Information Facility and the Atlas of Living Australia were compared with the same records from the Millipedes of Australia website, and a much larger number of errors and other problems in the aggregated datasets were revealed. Expand
A new millipede genus and a new species of Asphalidesmus Silvestri, 1910 (Diplopoda, Polydesmida, Dalodesmidea) from southern Tasmania, Australia
Noteremus summus gen. n., sp. n. occurs at 1100-1300 m on the summit of Mt Weld, southern Tasmania, while its congener N. infi mus sp. n. is troglobitic in caves in the Junee-Florentine karst, 30-40Expand
Revision of Agathodesmus Silvestri, 1910 (Diplopoda, Polydesmida, Haplodesmidae)
Agathodesmus Silvestri, 1910 includes A. baccatus (Carl, 1926) comb. n. from New Caledonia, A. bucculentus (Jeekel, 1986) comb. n. from Queensland, Australia, and A. johnsi sp. n. and A. steeliExpand
