Animals have evolved a variety of mechanisms to detect and avoid predation. The non-vocal sounds produced by some bird species during takeoff flights have been considered to function as an alarm call, because they may convey information about predati

Os diferentes fatores ecológicos influenciam como cada grupo animal responde morfológica e comportamentalmente ao ambiente em que ocupam. A disponibilidade de recursos alimentares, a capacidade de proteger-se de predadores, a temperatura, a precipi

O grupo mais afetado pelos efeitos negativos advindos da construção de rodovias é o dos vertebrados, tendo altas implicações para as populações de aves, especialmente no Cerrado. Dentre eles, estão os carniceiros que, em busca de alimento, fr
