The new study by Eizirik, Tatiane Trigo of Universidade Federal do Rio Grande do Sul, and their colleagues further revealed a complicated set of relationships between the tigrinas and two other species of Neotropical cats. That evolutionary history includes ancient hybridization and movement of genes between the pampas cat and the northeastern tigrinas (Leopardus tigrinus). In contrast, southern tigrinas (newly recognized as Leopardus guttulus) continue to hybridize with Geoffroy’s cats, leading to extreme levels of interbreeding between the species along their contact zone. Those patterns add to evidence that hybridization can and does occur between distinct animal species. As for the two tigrina species, the researchers suggest that they may be suited to different habitats, with the northeastern cats living primarily in savannahs, as well as dry shrub lands and forests, ...
