Resumo

Existem várias adaptações comportamentais utilizadas pelos mamíferos para reduzir os custos metabólicos da prevenção da perturbação da homeostase causada pelo calor excessivo, como buscar locais sombreados. Tocas são ótimos refúgios térmicos, pois fornecem microclimas mais frescos e protegidos. Aqui relatamos o primeiro registro de uma onça-pintada Panthera onca utilizando toca de tatu-canastra Priodontes maximus potencialmente como refúgio térmico. Esse comportamento foi registrado no Parque Nacional Grande Sertão Veredas, bioma Cerrado, Brasil Central. Como os cenários futuros globais preveem temperaturas mais elevadas, as tocas de tatu-canastra podem se tornar progressivamente mais importantes durante os períodos diários e sazonais de calor extremo.
