Island-dwelling Solenodon survived the asteroid that extinguished the dinosaurs–can it survive the Anthropocene? If you have never heard of the Solenodon until now, you’re not alone. The Solenodon (pronounced so-leen-o-don) lives only on two islands in the world–Cuba and Hispaniola. The nocturnal, insect-eating Solenodon is elusive and eccentric.

Island Living Changes Mammals

On islands, small mammals become bigger and large mammals get smaller. Ecosystem make-up and food resources are believed to be the cause of these size-change patterns.  The “Island Rule” describes the change in body size of mammals that migrate to islands: small mammals get bigger, and big mammals get smaller. Why is this? There is […]

Wedge Island: A Predator-Free Sanctuary for Endangered Species

Endangered species find refuge on predator-free Wedge Island, Australia. The protected area offers species a chance to bounce back from extinction.  The Critically Endangered Brush-tailed Bettong and Black-footed Rock Wallaby used to thrive in Australia. However, due largely to predatory invasive species such as feral cats and foxes on Mainland Australia, these mammals have experienced […]

Endangered Northern Quolls Benefit from Multi-pronged Conservation Measures

The Endangered Northern Quoll might be one of the cutest threatened native Australian species there is. This small mammal with big eyes and long whiskers recently experienced a devastating population crash. Why? We think invasive and introduced species are to blame…Particularly cats and feral herbivores like cattle pigs and buffalo. – Anthony Simms, senior project […]

In Evolutionary Twist, Island Foxes are “Genetically Flatlining”

Island Foxes set record for least genetic variation in a sexually reproducing species.  High genetic diversity among individuals in a species is usually optimal for survival, while low levels of genetic variation put a species at risk of extinction. In an evolutionary twist, Island Foxes native to the Channel Islands are challenging this long-standing principle. The […]
