Abstract: We examined temporal variability in a series of CEMP parameters collected over the ... the correlation of each parameter with breeding success. Breeding success was measured in terms of 1 ... ) the absolute number of chicks on the island which fully crèche and 2) the number of chicks crèched per ... nest with eggs.
