East African springhare East African springhare The East African springhare ("Pedetes surdaster"), is not closely related to the hare, but is a member of the Pedetidae, a rodent family. "Pedetes surdaster" was recognised by Matthee and Robinson in 1997 as a species distinct from the southern African springhare "(P. capensis)" based on genetic, morphological, and ethological differences. "P. capensis" from South Africa has fewer chromosomes (2n= 38) than does "P. surdaster" which has (2n = 40) and some other genetic variations. The species was confirmed by Dieterlen in 2005. This species is found in central and southern Kenya and most of Tanzania. A
Thermal equator both "summer" and "winter." Chennai, India, at 13 degrees north is considered to lie on the thermal equator at its longitude (80 degrees east). Thermal equator The thermal equator (also known as "the heat equator") is a belt encircling the Earth, defined by the set of locations having the highest mean annual temperature at each longitude around the globe. Because local temperatures are sensitive to the geography of a region, mountain ranges and ocean currents ensure that smooth temperature gradients (such as might be found if the Earth were uniform in composition and devoid of surface irregularities) are impossible, the
