Bonobo Sexual Behaviour and its Social Tension-Reducing Functions 1997
Bonobos show a particularly pronounced sexual activity and an extraordinarily broad spectrum of sexual contacts for primates. These also extend to non-reproductive life phases and partner combinations. For example, homosexual contacts and sexual contacts between young animals or with adults are frequent, and females are ready to mate throughout the menstrual cycle. Bonobos use sexual contacts not only for reproductive purposes, but also in the context of social conflicts, where they have a clear tension-reducing or peacemaking function.

Aufzucht von Bienenköniginnen 1992
Queen rearing is one of the most important areas of beekeeping. After explaining the breeding objectives, the three most common methods for rearing queen bees are described: Breeding in the queenless colony; breeding via the pre-brood box; breeding via starter and finisher. Special attention is also paid to the selection and presentation of the breeding material, selection and preparation of the care colony, controlled mating and the safe introduction of queens into the colonies.

Raumkonkurrenz bei der Prachtlibelle Calopteryx haemorrhoidalis 1991
The film shows the spatial distribution and the behaviour of the Mediterranean demoiselle Calopteryx haemorrhoidalis on typical reproduction waters. The great importance of suitable perches becomes obvious. These perches, e. g. single rush stems, are used by immature, hunting individuals as well as by reproductive males that are controlling territories from these sites. The latter chase all other individuals, the result being a spatial segregation between immature and reproductive specimens during the day. Typical behaviour, such as threatening, courting, copulation, and oviposition is shown in different film speeds.

Megaloprepus coerulatus (Pseudostigmatidae) - Flug und Fortpflanzungsverhalten 1988
For its reproduction, the megaloprepus dragonfly specifically relies on periodic puddles in tree holes and bromeliacea in tropical rain forests. Territorial males tenaciously defend these resources. Females lay their eggs in the water holes of the territorial males and are guarded by them. Any satellite male - i. e., one without a territory - who tries to grab a female is driven away by the territorial male.

Seevögel von Galapagos - Bewegungsweisen als Ernährungsstrategie 1984
The flight and feeding customs of the most important sea bird species of the Galapagos Islands are described. Some characteristic body and wing measurements are used to describe the flight of these species. The species which are able to forage furthest out at sea and deepest in the water are the most successfull on the Galapagos Islands, measured by their abundance. The least abundant bird is the lava-gull, a shore bird and surface-feeder.

Schafzucht im schottischen Hochland - Schur und Auktion 1980
Before shearing, done with electric devices and hand shears, lambs are separated from the flock. The lambs are not yet shorn but dipped in a disinfectant, parasiticidal liquid prescribed by law.

Schafzucht im schottischen Hochland - Lammzeit 1980
During the ewing-period the shepherd has to take especially care of the flocks. He has to assist the ewes in ewing, to control the feeding of the lambs, and to switch orphaned and abandoned lambs to ewes that have lost their lamb. This is still done by the traditional method of skinning: The dead lamb's skin is slipped on the abandoned lamb to deceive the mother ewe. At this time the shepherd must also warm newly-born, supercooled lambs inside the house and feed them artificially.
