| thermal physiology of a range-restricted desert lark. | much recent work on avian physiological adaptation to desert environments has focused on larks (passeriformes: alaudidae). we tested the prediction that the threatened red lark (calendulauda burra), a species restricted to very arid parts of south africa and which is not known to drink, exhibits highly efficient evaporative cooling and makes pronounced use of facultative hyperthermia when exposed to high air temperatures (ta). we also predicted that c. burra possesses similarly low basal metabol ... | 2019 | 30488103 |
