The Black Robin or Chatham Island Robin(Petroica traversi) is an endangered bird from the Chatham Islands off the east coast of New Zealand. In 1980 only five survived on Little Mangere Island. They were saved from extinction by Don Merton and his Wildlife Service team, and by "Old Blue", the last remaining fertile female.
If that one remaining female had died, then the species would now be extinct.
What else can I help you with?
When some members of a species become isolated they are less likely to become a new species true or false?
False.
When do you call a species endangered versus threatened?
A species is considered endangered when it is at a very high risk of extinction in the near future. A species is considered threatened when it is likely to become endangered in the foreseeable future if threats continue.
When are tigers likely to become extincy?
2015 for some species but 2020 if they are lucky.
Is a species that is likely to become extinct if protective measures are not taken immediately?
threatned
Will a species that lives a long time but has few offspring be more or less likely to become extinct after a sudden change in the environment than a species that has a short life but produces a lot of?
It might not but some animals can adapt very quick so it also might.
What are the changes in species on a tornado?
Not much. While some animals are likely to die, a tornado is unlikely to make a dent in the population of any species.
What would most likely occur if a species is adapted to an environment then the environment changes quickly?
Most of said species die, if there is a favorable mutation existent in the population that characteristic will become more prevalent. If not the species will most likely go extinct.
What will happen to the animals if air pollution doesn't stop?
If air pollution continues unchecked, animals are likely to experience respiratory issues, habitat destruction, and decline in population due to adverse effects on their health and food sources. Some species may become endangered or even face extinction.
Two species have the same niche. What is the most likely outcome when one species is the superior competitor?
The superior competitor is likely to outcompete the other species for resources, leading to a decrease in the population of the inferior competitor. This could potentially lead to the inferior competitor being displaced or evolving to occupy a different niche to reduce competition.
What populations can you think of that would not likely have a normal distribution?
There are many populations that would not likely have a normal distribution. Endangered species or unsocial animals would be such populations.
What is threatened with extinction?
Yes. These species are considerably lower than other species in numbers, due to hunting, habitat destruction, or other means. These animals can have from 1,000 to 10,000 left to be considered endangered. Critically endangered species have 200 or less left.
Which species list includes animals that would most likely be found in a taiga biome?
lynxes, moose, and pine trees
