For both voyages samples of penguin guano had profuse growth.
The growths were of mixed organisms and showed morphologically similar bacteria in all specimens that were the same as the bacteria grown from guano.
Again, there was no guano; no trees grew, and the handful of inhabitants told them that no birds visited.
Further, the baths on the deck were partially frozen by the cold, so some guano remained compressed in the tread.
The pebbles cemented in guano, are in a swale about 10 m east of the 1911 hut porch.
Of immediate consequence to the coastal peoples there are the disruptions to the fishing industry and to the birds who donate their nitrogen-rich guano.
Both soils were submitted to penguins guano during the summer season.
In general dry places harboured the guano with the most ammonia.
