In ntrast to nsy timat, a much greater number of studi has scribed activy patterns of margay across s range, suggtg that, overall, the speci is nocturnal [6, 8, 17, 30, 31, 36–39], though some areas may show a themeral pattern [40] first cycle of the Brazilian Natnal Actn Plan for the Conservatn of Small Cats (CENAP/ICMB) fed seven specific objectiv, one of which is to asss how different natural and anthropogenic procs fluence the populatns of small felids [41].
