Undesirable expatriates: Preventing the spread of invasive animals
...icate that once introduced, vertebrates have a 25% chance of becoming invasive. This figure, which appears to be true for other animals as well, is significantly higher than the 1% probability that dominates invasive species risk assessment. The 1% probability is based on plant invasions. Introduced animals...Scientists infuse rat spinal cords with brain-derived human stem cells
