Defining strategies for better use of nitrogen by crops requires sufficiently mechanistic models of nitrogen acquisition and use by plants. Bertheloot et al. describe the model NEMA (Nitrogen Economy Model within plant...

Gender segregation and sex allocation in pine
Many sex-ratio-related studies have focused on dioecious or monoecious herbaceous plants, but relatively few have looked at trees. Ne’eman et al. examine changes in gender segregation and sex allocation in Pinus...
CO2 effects on reproduction versus vegetative growth
Increased atmospheric CO2 concentrations may affect competition for resources between reproduction and shoot growth in forest species. Han et al. examine mature beech (Fagus sylvatica) trees in masting and non-masting...
Nitrogen and water effects on functional traits
Nitrogen and water effects on functional traits Changes in resource supply can have significant effects on plant functional traits. Ren et al. conduct a field study to examine the responses of five herbaceous perennial...
Patterns of resource allocation in a dioecious species
Patterns of resource allocation in a dioecious species Resource allocation between vegetative and reproductive growth will vary over time, and dioecious species may also adopt different strategies for allocation between...
Carnivorous plants prefer to kill in broad daylight
I owe thanks to Dr Andrej Pavlovič for being a patient guinea pig with my first press-release (you can find it on Science Daily) and to Lizzie Shannon-Little at OUP for helping put it out. It’s good timing because...

Growth–differentiation balance in stressed juvenile plants
The growth–differentiation balance hypothesis states that there is a physiological trade-off between growth and secondary metabolism. Cella Pizarro and Bisigato (pp. 297–307) investigate the response of six species...
