Interest in the well being of wild animals in their natural habitats is still lower than that of domesticated animals and captive wild animals. Urban development is one of the events that has the greatest impact on fauna, as it affects the survival and well being of wild species in many ways. This study aimed to record death by being run over of two Callithrix penicillata (black-tufted) marmosets in a fragmented environment by urbanization and to discuss how anthropic intervention modifies species behavior and influences their well being, and to suggest measures which can reduce the occurrence of incidents, thereby contributing to maintaining the fauna and their well being.

人们对野生动物在其自然栖息地中的福祉的兴趣仍然低于驯养动物和圈养野生动物。城市发展是对动物影响最大的事件之一，因为它在许多方面影响野生物种的生存和福祉。这项研究的目的是通过城市化在零散的环境中掠过两个Callithrix penicillata（黑簇绒）mar猴来记录死亡，并讨论人类干预如何改变物种行为并影响其健康，并提出可以减少此类事件发生的措施事件的发生，从而有助于维持动物群及其福祉。
