Malus sieversii in harsh climates unsuitable for "M. pumila", mainly for increased cold tolerance. "Malus sieversii" has recently been cultivated by the United States Agricultural Research Service, in hopes of finding genetic information of value in the breeding of the modern apple plant. Some, but not all, of the resulting trees show unusual disease resistance. The variation in their response to disease on an individual basis is, itself, a sign of how much more genetically diverse they are than their domesticated descendants. Malus sieversii Malus sieversii is a wild apple native to the mountains of Central Asia in southern Kazakhstan. It has
Egyptian fruit bat Egyptian fruit bat The Egyptian fruit bat or Egyptian rousette ("Rousettus aegyptiacus") is a species of Old World fruit bat. Étienne Geoffroy Saint-Hilaire originally gave this species the specific name of "egyptiacus" in 1810, but he later revised it to "ægyptiacus". In 1992, G. B. Corbet and J. E. Hill argued that this revision was invalid and changed the name back to "egyptiacus"; the 1999 "Mammalian Species" review used "egyptiacus" as well. However, Geoffroy's revision was argued to be valid in 2001 by D. Kock. He notes that the second spelling was "accepted almost universally by the scientific community", including
