Mammalian exocrine secretions XVIII : chemical characterization of interdigital secretion of red hartebeest, Alcelaphus buselaphus caama

Reiter, B.; Burger, B. V.; Dry, J. (Springer Verlag, 2003-10)

Gas chromatography, coupled gas chromatography-mass spectrometry (electron impact mode and chemical ionization with methane as reactant gas), gas chromatography-infrared spectroscopy, and derivatization techniques were ...

Chemical characterization of territorial marking fluid of male Bengal tiger, Panthera tigris

Burger, B. V.; Viviers, M. Z.; Bekker, J. P. I.; Le Roux, M.; Fish, N.; Fourie, W. B.; Weibchen, G. (Springer Verlag, 2008-05)

The territorial marking fluid of the male Bengal tiger, Panthera tigris, consists of a mixture of urine and a small quantity of lipid material that may act as a controlled-release carrier for the volatile constituents of ...

Pheromones of the Scarabaeinae, II : composition of the pheromone disseminating carrier material secreted by male dung beetles of the genus Kheper

Burger, B. V.; Munro, Zenda; Brandt, W. F. (Dieterich'sche Verlagsbuchhandlung, Wiesbaden (now Mainz), 1990-01)

Gel electrophoresis of the white flocculent pheromone disseminating secretions produced by males of the three dung beetle species, Kheper lumarcki, K. nigroacneus and K. subaeneus, revealed that three different proteins ...

Temporal changes in the neonatal recognition cue of Dohne Merino Lambs (Ovis aries)

Viviers, Marlize Z.; Burger, B. V.; Le Roux, Niel J.; Morris, John; Le Roux, Maritha (Oxford University Press (OUP), 2014-02)

The strong bond that is formed between ewe and lamb after parturition is important for lamb survival. Evidence exists that the ewe mainly employs olfactory recognition cues to distinguish her lamb from other lambs in the ...

Mass spectrometry in pheromone research

Burger, B. V. (Elsevier, 2005)

INTRODUCTION: The application of mass spectral techniques in the identifica tion of compounds invo lved in chemical communication between living organisms will be discussed in this a rticle. These biologically ...

Mammalian semiochemicals

Burger, B. V. (Springer Berlin Heidelberg, 2005)

Progress that has been made in research on the chemical aspects of mammalian semiochemistry over the past decade is discussed on the basis of examples from the most topical problem areas. The chemical characterization of ...

Olfactory ecology

Tribe, G. D.; Burger, B. V. (Wiley-Blackwell, 2011)

INTRODUCTION: As the morning sky over Zululand begins to lighten, and before the intense heat of the sun's rays breaks through the morning mist, the air is filled with the sound of flying dung beetles as they begin to ...

Neonatal recognition in sheep

Burger, B. V.; Viviers, Marlize Z.; Le Roux, Niel J.; Morris, John; Bekker, Jan P. I.; Le Roux, Maritha (Springer New York, 2013)

The strong bond formed between ewe and lamb shortly after parturition is an important factor in lamb survival. Evidence exists that the ewe can distinguish her lamb by its unique smell, but the constituents of such a ...

Thermal modulator array for analyte modulation and comprehensive two-dimensional gas chromatography

Burger, B. V.; Snyman, Tertia; Burger, Wina J. G.; Van Rooyen, Willie F. (Wiley-VCH Verlag, 2003-01)

Segmented thermal modulators were fabricated for the modulation of column effluent in one-dimensional gas chromatography, comprehensive two-dimensional gas chromatography, and as sample introduction devices in other ...

Semiochemicals of the scarabaeinae: VI. Identification of EAD-active constituents of abdominal secretion of male dung beetle, Kheper nigroaeneus

Burger, B. V.; Petersen, W. G. B. (Springer Verlag, 2002-03)

Using gas chromatography with flame ionization detection (FID) anal electroantennographic detection (EAD) in parallel, and employing chiral and achiral capillary columns, three constituents of the abdominal sex-attracting ...
