Edwards M, Wallis I, Foley W
J Comp Physiol B
. 2009 Sep;
180(2):247-57.
PMID: 19727760
We fed common brushtail possums artificial diets containing a buffer and the plant secondary metabolite (PSM), orcinol, to test the hypothesis that organic acids, common products of PSM metabolism, limit...

Inter-population differences in the tolerance of a marsupial folivore to plant secondary metabolites
DeGabriel J, Moore B, Shipley L, Krockenberger A, Wallis I, Johnson C, et al.
Oecologia
. 2009 Jul;
161(3):539-48.
PMID: 19585152
Plant secondary metabolites (PSMs) strongly influence diet selection by mammalian herbivores. Concentrations of PSMs vary within and among plant species, and across landscapes. Therefore, local adaptations may cause different populations...

DeGabriel J, Wallis I, Moore B, Foley W
Oecologia
. 2008 Feb;
156(1):107-16.
PMID: 18288495
Many regard the concentrations of nitrogen (N), tannins and plant cell wall constituents (fibre) as key indicators of food quality and habitat suitability for browsing herbivores; yet there is no...

Ostrand F, Wallis I, Davies N, Matsuki M, Steinbauer M
J Chem Ecol
. 2008 Jan;
34(2):153-67.
PMID: 18213498
The autumn gum moth, Mnesampela privata, utilizes several species of Eucalyptus planted outside regions of endemism within Australia. We investigated whether foliar monoterpene composition influenced oviposition in the field on...

Henery M, Moran G, Wallis I, Foley W
New Phytol
. 2007 Aug;
176(1):82-95.
PMID: 17696979
Leaves of eucalypt species contain a variety of plant secondary metabolites, including terpenoids and formylated phloroglucinol compounds (FPCs). Both terpene and FPC concentrations are quantitative traits that can show large...

Marsh K, Wallis I, Foley W
Oecologia
. 2007 Aug;
154(2):283-90.
PMID: 17690913
In a given period of time, herbivores often eat less as dietary plant secondary metabolite (PSM) concentrations increase. This reduction in total food intake is interpreted as a need for...

Andrew R, Wallis I, Harwood C, Henson M, Foley W
Oecologia
. 2007 Jun;
153(4):891-901.
PMID: 17593399
Plants encounter a broad range of natural enemies and defend themselves in diverse ways. The cost of defense can be reduced if a plant secondary metabolite confers resistance to multiple...

Ecology
. 2007 May;
88(3):716-28.
PMID: 17503599
Exploring the spatial distribution of variation in plant secondary metabolites is critical for understanding the evolutionary ecology of biochemical diversity in wild organisms. In the present study, concentrations of foliar...

Biol Lett
. 2006 Dec;
1(1):64-7.
PMID: 17148129
The koala is the quintessential specialist herbivore, feeding almost exclusively on Eucalyptus foliage. Consequently, the limitations imposed on the koala's diet by plant defences indicate the extent to which evolutionary...

Ecology
. 2006 Aug;
87(8):2103-12.
PMID: 16937649
Most herbivores eat more and survive better when they have access to a variety of foods. One explanation involves the detoxification of plant secondary metabolites (PSMs). By feeding from a...
