Lachrymal secretion in tenrecs: physiological, behavioral and phylogenetic contexts (Tenrecinae, Afrosoricida)
Bálek, Jiří ; Horáček, Ivan (advisor) ; Sedláček, František (referee)
The secretion of white liquid around the eyes and nose with a spiny tenrecs Echinops telfairi and Setifer setosus mentions for the first time Poduschka in 1974, but until now this phenomenon in these species no one paid any detail. Similar secretion was described in Mountain beaver or by shrews. The impetus for shedding the excitement caused by the presence of an individual female or another male or its odor. Males secretions also used for marking territory. A total of 70 samples of eye secretions from ten male Echinops telfairi during the entire active season (from March to October) have been collected within this study. For protein detection method was used two-dimensional polyacrylamide gel electrophoresis (2D PAGE) and subsequent identification by mass spectrometry. An autopsy of the eye area was performed for representatives of all four genera of the subfamily Tenrecinae (Tenrec, Setifer, Echinops, Hemicentetes), died in Pilsen Zoo. It was found that a) species of pinholes that produce ocular secretions are significantly higher tear and Harder's gland, b) secretions contain lipocalins - proteins with the ability to transmit pheromones and other hydrophobic molecules, c) secretions of the orbital region having a different composition than the secretions from the nasal area (significantly lower protein...
