The genetic blueprint for New Zealand’s national bird reveals the kiwi’s adaptation to a nocturnal, ground-dwelling lifestyle around 35 million years ago has meant poorer eyesight, but superior smelling powers

Published online in Genome Biology, the study by researchers in Germany identified genetic mutations that have deactivated genes related to colour vision, as well as other mutations that have enhanced the kiwi’s sense of smell compared to other birds.

The kiwi is an evolutionary phenomenon, and an endemic species to New Zealand, a land that was geographically isolated after its separation from Godwana 80 million years ago. This isolation makes New Zealand ideal for studying evolutionary processes. Continue reading →

Research suggests owners are reluctant to accept the cat predation risk to wildlife and a cat welfare approach may be needed 

Wildlife killer cat

Domestic cats have been introduced by humans across the world and growing cat populations are placing local wildlife under greater pressure. Cat predation compounds the survival problem by adding to habitat loss and food scarcity for some species.

Free-roaming cats on islands have contributed to the extinction of native bird, mammal, and reptile species unable to fend off this introduced predator. In mainland environments, cats are impacting local bird and mammal populations, with large numbers killed each year. Continue reading →
