  Behavioural observations of interactions in a free-ranging lynxLynx lynx family at kills

  摘要：

  The behaviour of a free-ranging female lynx Lynx lynx Linnaeus, 1758 and her kittens at 12 different kills was studied for 44 hours of observation from September 1996 to March 1997. The development of interactions at kills of a lynx family group showed the following pattern: until the end of September we often observed two lynx, usually both kittens, food from the kill at the same time. After the age of four months aggression between kittens was observed frequently, with the bigger kitten being dominant. From September the kittens were never again seen feeding together at the kill, However, we never observed fighting, and aggressive behaviour did not increase with the age of the, kittens. Whereas until December one of the kittens was always first at the kill, from January onwards it was mostly the adult female who ate first. She introduced her kittens to the home range of a neighbouring female where the family break-up occurred. The kittens were last seen together with their mother on 26 March. Dispersal seemed to be initiated by the female abandoning the kittens.

  [EN] Anti-thrombotic compositions include anti-thrombotic steroids together with potentiators thereof (e.g. heparin or cyclodextrin) or with a thrombolytic substance such as tissue plasminogen activator. Therapy, in which thrombosis in a mammal at risk is prevented or treated, comprises administering an effective amount of a steroid possessing anti-thrombotic activity or a pharmaceutically acceptable salt thereof.
