Prägung von Entenküken - Nachfolgereaktion

Anas platyrhynchos (Anatidae). Imprinting to the parents occurs in mallards in the sensible phase (8 to 24 hours after hatching). In this time period imprinting to other objects (dummies, people) can also take place. Optical and acoustic stimuli of the object become the key stimuli for the following response. The bond to a replacement object lasts until the ninth week after hatching.

Psychopathologie und Motorik bei präseniler und seniler Demenz

On the basis of selected patients with senile dementia, Alzheimer's disease and Pick's atrophy, who were particularly suitable for film purposes, the auther examines the psychopathology and motor activity of presenile and senile diseases. In this regard the emphasis is placed on a subtile demonstration of the pathological deterioration of reflexes which are near the brain stem. In addition of this, particular attention is paid to the deterioration of speech.

Verhaltensweisen beim Dülmener Primitivpferd (Equus caballus) - Hautpflege, Fortpflanzung, Erkunden und Meiden, Mimik und Ausdrucksbewegungen

Skin hygiene: a mare rubs herself on a post; a foal nibbles itself with its teeth; a stallion rolls around on the ground. Several wild horses are congregated at a watering-place. The social skin hygiene of the horses involves mutual nibbling. Mating. Ascertainment and shunning: In 1962, the evasion distance kept between the Dülmen wild horse and a human being was about 3 metres, observed both by individual animals and family groups. On the other hand, the whole herd will flee before a human being on all fours. Mimic and expressive movement: examples of nonconformative expressive behaviour are shown in yawning, sulking, drolly and sensual facial expressions.

Malachius bipustulatus (Malachiidae) - Balz und Kopulation

The film deals with the mating of the malachiid Malachius bipustulatus L. The male possesses in the anterior part of the head, a secreting organ (the head cavity) which is proffered to the female for palpation with the mouthparts (the mandibles). During this chewing act, the tips of the two pairs of palps of the female, which carry gustoreceptors, come into contact with the secreted flavour. The female is only willing to mate after several takings of the secretion. The male tests the willingness of his partner to copulate by touching her at the back. The film shows from various angles, the encounter, chewing act, movement of the female maxillary palps (greatly enlarged), the test touching and copulation.

Tilapia tholloni (Cichlidae) - Brutpflege

Both sexes of the substrate brooding Cichlid Tilapia tholloni take care of their eggs - which are sticking to the substrate - by fanning them and "picking" at them. Newly hatched larvae are sticking to the substrate by means of cement-glands. Later on the parents may transport the young to another part of the pit or to another pit. When the swim-bladder is beginning to get filled the hopping movements of the young gradually change to normal swimming. At this time the parents will be found amidst the cloud of young fish with the young ones keeping at a certain distance from the parents.

Tilapia tholloni (Cichlidae) - Paarbildung

A female of the substrate brooding Cichlid Tiapia tholloni - ready to spawn - keeps attempting to enter the territory of the male which in the beginning rather aggressively drives the female away. Gradually a pair bond between the partners is established. Soon both of them are digging their pit and defending their territory.

Stephanopyxis turris (Centrales) - Ungeschlechtliche Fortpflanzung durch Dauersporen

Stephanopyxis is capable of interrupting its vegetative reproduction by the formation of resting spores. The resting spores are formed in pairs via two differentiating cell divisions. The first division is equal, the second, however, extremely unequal, since during growth in the longitudinal direction the cell contents are polarized. Resting spores germinate by beginning with normal vegetative cell divisions. The walls of the spores are not shed but passed along from division to division.

Stephanopyxis turris (Centrales) - Geschlechtliche Fortpflanzung; Differenzierung der Spermien

The formation of male gametes of the Stephanopyxis turris is initiated by two or three differentiating divisions. From this, four or eight spermatogoni with shells emerge, enclosed in the mother cell. These enter into meiosis as spermatocytes. Since there is no cytocinesis, thw two meiotic divisions yield spermatocytes with four nuclei. Sperms with one flagellum and without plastides are formed. The main part of the plasma of the spermatocytes as well as all plastides are left behind in residual bodies.

Stephanopyxis turris (Centrales) - Geschlechtliche Fortpflanzung; Differenzierung der Oogonien, Auxosporenbildung

The oogonia of the Stephanopyxis turris, are formed directly from the vegetative cells. Pronounced longitudinal growth is followed by the two meiotic divisions of the nucleus; there are no cytokinesis. After each division of the nucleus one of the daughter nuclei becomes pycnotic. The one-egged oogon opens up and is fertilized by a spermium. The zygote swells up to form the auxospore, increasing significantly in volume. By succedaneous secretion of two shells the first cell emerges from the auxospore; this cell grows to become the colony of a new clone.

Stephanopyxis turris (Centrales) - Ungeschlechtliche Vermehrung durch Zweiteilung

The cells of the colony-forming Stephanopyxis turris multiply vegetatively by bi-division. The numerous lobed plastides double during the interphase by simple intersection. Cell division is initiated by marked longitudinal growth with migration of the nucleus to the equator of the cell. In the anaphase of the division of the nucleus the central spindle that is typical for diatoms appears. The fission of the protoplast starts near the nucleus. Cell division is completed with the secretion of a new lower sell for each of the two daughter cells.

Cervus elaphus (Cervidae) - Paarungsverhalten

The film contens the mating of the Red Deer and the sexual behaviour belonging to this complex. It shows: mating postures: "Flehmen", roaring and ritualized chewing movements, contact dismating: mounting and copulation. By the film it is shown, that to serve the hind the stag carries out a quick jump when he covers the hind with his body, then rises up vertically and for a short moment has no contact to the ground.
