Foliar pH as a new plant trait: can it explain variation in foliar chemistry and carbon cycling processes among subarctic plant species and types?

Cornelissen, J. Hans C.; Quested, H. M.; Logestijn, R. S. P.; Perez-Harguindeguy, N.; Gwynn-Jones, Dylan; Diaz, S.; Callaghan, Terry V.; Press, M. C.; Aerts, Rien (2006-03)

Plant traits have become popular as predictors of interspecific variation in important ecosystem properties and processes. Here we introduce foliar pH as a possible new plant trait, and tested whether (1) green leaf pH or ...
Leaf digestibility and litter decomposability are related in a wide range of subarctic plant species and types

Kondratchuk, Alexandra; Aerts, Rien; van Logtestijn, R. S. P.; Cornelissen, J. Hans C.; de Beus, M. A. H.; Callaghan, Terry V.; Gwynn-Jones, Dylan; Quested, H. M. (2004-12-08)

1. Herbivory and litter decomposition are key controllers of ecosystem carbon and nutrient cycling. We hypothesized that foliar defences of plant species against vertebrate herbivores would reduce leaf digestibility and ...
