Whether wild animals or domestic animals: in the Anthropocene, the age of humans, they all face a number of challenges. In “Animal World at the Limit” the behavioral biologists Norbert Sachser and Niklas Kästner show the impressive adaptability of animals – and their limits. The authors draw on an almost endless repertoire of absurd and funny studies, but also disturbing research results.
For example, they explain what more frequent tropical storms have to do with the size of lizard feet. It continues with fish species that live in polluted waters because, thanks to rapid evolution, they defy man-made toxins. Using water fleas, scientists are able to look back into the 1950s and draw conclusions about climate change. And in Australia, an arms race is underway between human residents and hungry cockatoos playing garbage collectors.
In addition to the winners, the focus is also on the losers of the Anthropocene, such as spiny iguanas, which are mating less frequently due to rising temperatures. It also highlights an often overlooked aspect of the animal world: the abilities of pets and farm animals.
With a mixture of interesting research and exciting storytelling, the two scientists skillfully illustrate how far animals can adapt. However, the conclusion is clear: people also have to accommodate them.
