Conifers dominated the lowland tropics 100 million years ago, but have now been largely replaced by angiosperms, coincident with a large decline in atmospheric CO2. Using greenhouse treatments of pre-industrial...
Some Lupinus species produce cluster roots in response to low plant phosphorus (P) status. Wang et al.Β measure relative growth rate (RGR) among three lupin species, L. albus, L. pilosus and L. atlanticus, with similar...
The dynamics of humid forests are thought to involve a trade-off between shade tolerance and growth in high light. Lusk et al.Β compare seedling growth and functional traits of tropical and cool-temperate Australian...
Heteroblasty, crowding and shade avoidance Acacia implexa shows leaf heteroblasty, developing compound, transitional and modified leaves (phyllodes), and previous experiments have shown that shade can alter the ontogeny...
