values were higher for the CONTROL and LEAF treatments than the
WOOD and TREE treatments (P < 0.05). The CONTROL d15N value
was lower than that of termite sheetings. The highest d15N was
measured for the LEAF treatment and lowest for TREE (P < 0.05 in
all cases). There was no significant difference between the WOOD
d15N value and that measured for other termite sheetings
(P < 0.05).
