The requirements for the development of lampenflora are sufficient (artificial) light and moisture. An increase in nutrient content (e.g. fertilizer usage on land above the cave) or heat (e.g. incandescent lighting) may lead to an increase in lampenflora. The germs, seeds or spores can get brought into the cave by air, water, animals or people. [7]
One paper estimated that in Austria, at an intensive farming facility used to fatten up about 1800 growing pigs at a time, the already observed warming between 1981 and 2017 would have increased relative annual heat stress by between 0.9 and 6.4% per year. It is considered representative of other such facilities in Central Europe. [13]
A fresh cow is a dairy term for a cow (or a first-calf heifer in few regions) who has recently given birth, or "freshened." The adjective applying to cattle in general is usually bovine. The terms bull, cow and calf are also used by extension to denote the sex or age of other large animals, including whales, hippopotamus, camels, elk and elephants.
Female cattle, also referred to as "heifers" in agriculture, will gradually enter standing estrus, or "standing heat," starting at puberty between 9 and 15 months of age. The cow estrous cycle typically lasts 21 days. [5] Standing estrus is a visual cue which signifies sexual receptivity for mounting by male cattle.
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
A cow was a great advantage to a villager as she produced more milk than her calf needed, and her strength could be put to use as a working animal, pulling a plough to increase production of crops, and drawing a sledge, and later a cart, to bring the produce home from the field. Draught animals were first used about 4,000 BC in the Middle East ...
Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC.
ABBA Christmas — This infomercial spoof promotes a never-released album of holiday songs from "The Fleetwood Mac of cold weather" (Bowen Yang, episode host Kate McKinnon, and McKinnon's fellow SNL alums Maya Rudolph and Kristen Wiig), all set to the tunes of their well-known classics (e.g. "Gifts for Me, Gifts for You").
