“…The four study species (Panthera leo, P. onca, P. pardus, and P. tigris) have similar gestation periods (88-112 days: Seymour, 1989;Haas et al, 2005;Sunquist & Sunquist, 2009;Stein & Hayssen, 2013) and litter size (1-4 cubs: Maz ak, 1981;Seymour, 1989;Sunquist & Sunquist, 2002;Haas et al, 2005). The smallest weight at birth is that of P. pardus (300-700 g Hemmer, 1979), followed by P. onca (700-900 g, Seymour, 1989), P. leo (1000 g, Hemmer, 1979), and P. tigris (780-1600 g, Maz ak, 1981).…”
