Distance estimation in prey catching was as exact in monocular toads (Bufo bufo (L.)) as in binocular ones. Application of Atropine or Miotic had no significant effect on binocular animals, whereas in monocular toads it made accurate distance estimation impossible. The accommodative state of the eye is decisive for depth estimation of monocular, but not of(More)
The evaluation of calculated protein structures is an important step in the protein design cycle. Known criteria for this assessment of proteins are the polar and apolar, accessible and buried surface area, electrostatic interactions and other interactions between the protein atoms (e.g. H..O, S..S), atomic packing, analysis of amino acid environment and(More)
Groups of juvenile Salamandra salamandra were raised selectively with different types of prey. The influence of these conditions on the movement pattern preference was studied during the first six months after metamorphosis. Responses to a black horizontal bar moving continuously or stepwise at step frequencies between 0.25 and 8 steps/s were tested. The(More)
Two groups of newly metamorphosed Salamandra salamandra (L.) were raised with living and with stationary prey, respectively. One year later, the group which had experience exclusively with stationary prey was significantly better in responding to stationary prey than the group which only had experience with moving prey. This was the case both under light(More)
