READ THE FOLLOWING PARAGRAPH AND ANSWER THE FOLLOWING QUESTIONS:-
Biologists in New Zealand are baffled by the sudden death of a large number of the
World’s rarest species of penguins. At least a third of the 400 yellow-eyed penguins that
live on the Otago Peninsula, in New Zealand's South Island have died since December. The
loss represents around 60 percent of all yellow-eyed penguins and threatens to extinguish
the mainland population.The disappearance of this group of penguins is particularly serious
for the species because the birds are genetically distinct from those on the Auckland Island
and Campbell Island. Their disappearance would narrow the species' gene pool
considerably.
The first penguins died in December and by February the population had crashed.
Postmortem examinations showed no sign of poisoning by heavy metals or pesticides, nor
was there any sign of a virus. Whatever killed the birds acted very quickly in the eight hours
they were at sea feeding on the day they died - and most of the corpses recovered were
near their home beaches."Whatever it seems to make them sick, then head
for home and collapse on the beach" said one of the scientists.
Suggestions of a cause range from a change in food supply caused by climatic
change,to poisoning by a biological toxin - perhaps from an algal bloom. The sea has been
particularly warm this summer, but temperature alone would not kill the penguins, nor had
the unusual climate conditions interfered with the birds' feeding, None of the dead birds
showed any signs of disease.
(a) Why were the Biologists in New Zealand baffled ?
(b) Where in the world do yellow-eyed penguins live?
(c) Why is the disappearance of the yellow eye group of penguins serious for the species?
(d) What did the post-mortem examination show?
