Lizard epidermal gland secretions I : chemical characterization of the femoral gland secretion of the sungazer, Cordylus giganteus

Louw, Stefan; Burger, B. V.; Le Roux, Maritha; Van Wyk, Johannes H. (Springer Verlag, 2007-09)

The giant girdled lizard or sungazer, Cordylus giganteus, is endemic to South Africa. It has been suggested that in this species, as in other lizard species, epidermal glands in the femoral, pre-cloacal regions, and cloacal ...

Mammalian pheromone studies - III : (E,E)-7,11,15-trimethyl-3methylenehexa-deca-1,6,10,14-tetraene, a new diterpene analogue of ß-farnesene from the dorsal gland of the springbok, Antidorcas marsupialis

Burger, B. V.; Le Roux, Maritha; Spies, H. S. C.; Trutor, Verona; Bigalke, R. C. (Elsevier, 1978)

The secretions produced by the cutaneous glands of mammals are generally considered to be involved in conspecific chemical communication, acting as pheromones. From a review of mammalian chemical ecology it appears that, ...

Headspace analysis : a novel method for the production of capillary traps with ultra-thick stationary phase layers

Burger, B. V.; Le Roux, Maritha; Burger, Wina J. G. (John Wiley & Sons, 1990-11)

The development by Grab and Habaich of a headspace analytical technique which organic volatiles are trapped in short capillary traps coated with a layer of fine activated charcoal particles (COTs) or a layer of a suitable ...

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 ...

Simplified analysis of organic compounds in headspace and aqueous samples by high-capacity sample enrichment probe

Burger, B. V.; Marx, Brenda; Le Roux, Maritha; Burger, W. J. G. (Elsevier, 2006-07)

A sample enrichment probe (SEP) consisting of a thin rod of an inert material and provided at one end with a short sleeve of polydimethylsilicone rubber was used for the high-capacity sample enrichment of analytes from ...

Elemental sulfur identified in urine of cheetah, Acinonyx jubatus

Burger, B. V.; Visser, Runine; Moses, Alvira; Le Roux, Maritha (Springer Verlag, 2006-06)

The urine of the cheetah, Acinonyx jubatus, is almost odorless, and probably for this reason, it has not attracted much attention from scientists. Using gas chromatography-mass spectrometry, we identified 27 and 37 ...

Lizard epidermal gland secretions II : chemical characterization of the generation gland secretion of the sungazer, Cordylus giganteus

Louw, Stefan; Burger, B. V.; Le Roux, Maritha; Van Wyk, Johannes H. (American Chemical Society and American Society of Pharmacognosy, 2011-06)

In lizards, the epidermal glands of the femoral and precloacal regions are involved in the production of semiochemicals. In addition to its femoral glands, the giant girdled lizard, or sungazer, Cordylus giganteus, which ...

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 ...

Olfactory cue mediated neonatal recognition in sheep, Ovis aries

Burger, B. V.; Viviers, Marlize Z.; Le Roux, Neil J.; Morris, John; Bekker, Jan P. I.; Le Roux, Maritha (Springer Verlag, 2011-10)

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