IMPACTS OF ROOT COMPETITION IN FORESTS AND WOODLANDS: A THEORETICAL FRAMEWORK AND REVIEW OF EXPERIMENTS
Predicting the types of forest in which root competition affects seedling performance, and the types of plants that respond most strongly to release from root competition. Testing predictions by reviewing experiments in which tree seedlings and forest herbs are released from belowground competition, usually by cutting trenches to sever the roots of surrounding trees. Coomes,Continue reading “IMPACTS OF ROOT COMPETITION IN FORESTS AND WOODLANDS: A THEORETICAL FRAMEWORK AND REVIEW OF EXPERIMENTS”
Herbivory and plant competition reduce mountain beech seedling growth and establishment in New Zealand
Experimental manipulations on transplanted and naturally occurring mountain beech seedlings to show the effects of deer browsing and competition from deer-induced, herbaceous turf communities. Husheer, S.W.; Robertson, A.W.; Coomes, D.A.; Frampton, C.M. 2005 PDF
Factors Preventing the Recovery of New Zealand Forests Following Control of Invasive Deer
We consider the contributions that scientific research can make to effective forest restoration, including empirically based forest-dynamics models that place regeneration in the context of other processes, such as disturbance, soil fertility, and multiple invasive organisms using the example of Red Deer in New Zealand.

Designing systems to monitor carbon stocks in forests and shrublands
This paper describes a system for monitoring carbon in New Zealand’s forests and shrublands 6.3 and 2.6 million ha, respectively), which was tested on a 60 km-wide transect across the South Island. Coomes, D.A.; Allen, R.B.; Scott, N.A.; Goulding, C.; Beets, P. 2002 PDF
Disturbances prevent stem size-density distributions in natural forests from following scaling relationships
Enquist and Niklas propose that trees in natural forests have invariant size-density distributions (SDDs) that scale as a -2 power of stem diameter, although early studies described such distributions using negative exponential functions. Using New Zealand and ‘global’ data sets, we demonstrate that neither type of function accurately describes the SDD over the entire diameterContinue reading “Disturbances prevent stem size-density distributions in natural forests from following scaling relationships”
The hare, the tortoise and the crocodile: the ecology of angiosperm dominance, conifer persistence and fern filtering
Angiosperm trees often dominate forests growing in resource-rich habitats, whereas conifers are generally restricted to less productive habitats. We investigate whether competition with ferns and deeply shading trees also contributes to a failure of conifers to regenerate in resource-rich habitats. Coomes, D.A. et al. 2005 PDF
Are differences in seed mass among species important in structuring plant communities? Evidence from analyses of spatial and temporal variation in dune-annual population
Analysis of the population and spatial structures of coastal annual-plant communities, across ten dunes and a three years period, to explore the role of seed mass in structuring these communities. Coomes, D.A.; Rees, M.; Grubb, P.J.; Turnbull, L. 2002 PDF
Comment on “A Brief History of Seed Size”
A comment on ‘A Brief History of Seed Size’ by Mole et al. in which an argument is made against understanding the association of greater seed size with greater plant height through use of Charnov’s life-history theory for mammals. Grubb, P.J.; Coomes, D.A.; Metcalfe, D.J. 2005 PDF
Colonization, tolerance, competition and seed-size variation within functional groups
There is evidence from studies within functional groups that seed size does trade off against number of seeds and dispersal of those seeds. Coomes, D.A.; Grubb, P.J. 2003 PDF
