The Sumatran rhinoceros, also known as the hairy rhinoceros or Asian two-horned rhinoceros (Dicerorhinus sumatrensis), is a rare member of the family Rhinocerotidae and one of five extant species of is the only extant species of the genus is the smallest rhinoceros, although it is still a large mammal; it stands – cm (– ft) high at the Class: Mammalia.
The hirola (Beatragus hunteri), Hunter's hartebeest or Hunter's antelope, is a critically endangered antelope species found on the border between Kenya and were discovered by Kenyans living in the area in It is the only extant member of the genus Beatragus.
The global hirola population is estimated at – animals, there are no hirola in captivity and the wild Class: Mammalia. Oestrus is short in the cow, with ovulation occurring 10–12 hours after the end of oestrus.
During the next 6 hours the oocyte travels about a third of the way down the uterine tube, during which time fertilisation occurs, about 30 hours after the onset of oestrus (Robinson, ).The best conception rates occur if insemination is carried out in the middle to the end of standing.
Observations of captive servals suggest that when a female enters oestrus, the rate of urine-marking increases in her as well as the males in her vicinity. Zoologist Jonathan Kingdon described the behaviour of a female serval in oestrus in his book East African Mammals.
He noted that she would roam restlessly, spray urine frequently Class: Mammalia. Red panda's biology, where little (recent) research has been published, is conspicuous by their absence while others are summarized. It emphasizes how familiar the red panda is to people in its range states as well as in the wider global community and how its name and image are perceived by various cultures.
The Biodiversity Heritage Library works collaboratively to make biodiversity literature openly available to the world as part of a global biodiversity community.

Oestrosis, caused by the larvae of Oestrus ovis, commonly known as sheep nose bot, is an obligatory cavitary myiasis of sheep and goats. Oestrus ovis is a widespread parasite, but little is known about the prevalence of oestrosis at the global and broad geographical levels.

Economic Importance for Humans: Positive. saxatilis is not of much economic importance for the human population. However, many human populations use members of the genus Lepus as a food source, and it is likely that local people probably eat these hares occasionally.
Its fur is of minimal value, but it is sometimes used within the lining of various garments including gloves. Full text of "Smithsonian miscellaneous collections" See other formats. History of Animals (Thompson)/Book V.
As we carried on our previous discussion genus by genus, so we must attempt to follow the same divisions in our present argument; only that whereas in the former case we started with a consideration of the parts of man, in the present case it behoves us to treat of man last of all because he involves.
