Environmental determinants of circadian activity of free-ranging iberian lynxes

From February 1983 to May 1985, 12 Iberian lynxes (Lynx pardinus) (six adults and six juveniles) were radiotracked at hourly intervals for 114 24-h periods at Doflana National Park, southwestern Spain. Nine environmental factors were related, by season and age class, to 12 indices of daily activity...
