Výzkum nejvhodnějšího krmení pro vysokou zvěř.
Extended description:
Výzkumný ústav lesa a myslivosti na Zbraslavi chová jelení a srnčí zvěř. Mezi nimi nalezneme také ...vzácný kus jelena wapiti. Jelikož byl nebezpečný svému okolí, tak mu musely být odřezány parohy. Naproti tomu muflon se už se svým zajetím smířil. Každých 10 dní se zdejší zvěř váží, aby se zjistilo, jaká potrava je pro každý druh nejvýhodnější. Krmení se sleduje nepřetržitě celých 24 hodin denně. Získané poznatky se využijí při přikrmování zvěře ve volné přírodě. Má-li zvěř dostatek potravy, neokusuje potom lesní kultury.
The Research Institute of Forest and Wildlife in Zbraslav keeps deer and roe deer. We can find also a rare kind of the Wapiti deer here. Since it was dangerous to its surrounding, they had to cut off its antlers. The moufflon, on the other hand, has put up with living in captivity. Every 10 days, the local deer is weighed to determine what food is the best for each type. Feeding is monitored continuously for 24 hours a day. The knowledge gained is used for feeding animals in the wild. If the animals have enough food, they do not nibble the trees.

Československé filmové týdeníky byly původně vysílány v kinech v letech 1945 až 1989. Od roku 1995 jsou opět vysílány v České televizi každý týden přesně po padesáti letech. Uvedené datum vysílání je datum prvního uvedení tohoto týdeníku ve vysílání České televize.
Czechoslovak Newsreels were produced and shown between 1945 and 1989. Since 1995 they have been broadcast on TV exactly 50 years after their original run in theaters. The broadcast date provided is the date of the first transmission of this news item on Czech Television.
Research of the best food for deer.
Water erosion in the catchment basin of the Jeleni Brook The study on water erosion in the catchment basin of the Jeleni Brook was carried out in the years 1995-1999. The catchment of the Jeleni ...Brook has complex relief, receives frequent precipitations and thus is more threatened by water erosion. Soil cultivation and water from quickly melting snow can also be the factors affecting soil erosion. Waters from the melting snow produce rills of the following dimensions (mean values): width from 11.5 to 13.6 cm, depth - from 6.4 to 7.1 cm and length - from 39 to 112 m. The mean values of soil losses vary from 0.5 to 2.02 t·ha-1. Erosion caused by intensive storm precipitation occurs less frequently but makes much higher soil losses. One of the registered incidents shows that 51.6 t·ha-1 (4.5 mm of soil layer) can be washed out from the area of 0.66 ha. Combined effect of outwashing and ploughing in lower parts of slopes created new forms of relief such as agricultural terraces (escarps). Agricultural terraces assume the shape of scarps up to 2 m high and of different length (e.g. 150 m) along with the land use border-lines between e.g. forest and field or field and grassland. Agriculturally used soils within this catchment need protection based mainly on agrotechnical measures or on alteration of land use. Some areas should be afforested.
The second part of this text on the systematics and phylogeny of extant cervids focuses on Cervini. This group includes more than 20 various deer species inhabiting forests and grasslands of Europe, ...Asia, and North America; 15 of them listed in the Red Data List of endangered species. During the last 10 years many papers have been published on their phylogeny. Its recent overview including relationships between individual species is summarized.

This article discusses an animal sculpture pendant, probably representing a deer, made from a tin-lead alloy, found in a ...waste layer at the bottom of a Medieval mill race. This item is unusual for the Czech Republic, although numerous similar items are known from Western Europe.
