The availability of nitrogen represents a key constraint on carbon cycling in terrestrial ecosystems, and it is largely in this capacity that the role of N in the Earth's climate system has been considered. Despite this, few studies have included con

A detailed study of complexation of the sodium ion by HMPA2 has been made using the system[Formula: see text]where HMPA is observed to be a strong donor towards Na+ but does not complex AlEt4−. This system forms two liquid phases at low HMPA:Na+ mo

The hypothesis that males of certain species of the pompilid genus Cryptocheilus Panzer are polymorphic, first proposed by H. Wolf, is examined critically in the light of modern knowledge of the mating systems of Hymenoptera and the known biology of
