    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract By implanting thermal loggers deep in the body cavities of lions, eland antelopes, wildebeest and impala in a hot (up to 48°C) and arid (~ 300 mm p.a.) savanna system with cold winters (minimally 4°C at night) in the northern border area of South Africa, we have measured core body temperatures over the day for a number of months. Temperature measurements were sent every 20 minutes to a receiver in a neck collar, from which they were transferred by cell-phone (in case of the lions) or satellite. Antelopes and lions warmed up considerably during the day but the antelopes started shedding heat immediately after sunset, reaching a minimum body temperature just before sunrise. Lions decreased their temperature several hours later: they maintained optimal temperatures for explosive power output when antelopes had lost theirs. The antelopes’ thermal strategy appear to be aimed at minimizing water loss, giving their predators an advantage. The research has clear implications for the water point closure policy, since for different species of antelope the interaction between thermal strategy and water use is ‘played out’ differently.
