You get a better model of the forest when you look at the individual trees

The computing principle GIGO states that if the data you put into a model is garbage, then the output will be too. Jie Yang and colleagues have been tackling the problem of modeling of tropical tree growth. What data is the best data for these models? One approach that you could expect is to take an average of traits as data. “While collecting trait data from a small number of individuals may be a pragmatic approach, particularly in diverse systems, the analysis of population- or species-mean trait data is conceptually misaligned with the vast evolutionary ecology literature relating traits to...

Resource allocation trade-offs in a mast-seeding conifer

Three key functions are required for the long-term persistence of tree populations in a landscape. Broadly speaking, trees must acquire and allocate resources to maintain or increase their biomass, to tolerate or resist stress, and to pass genetic material to new generations. Yet the three central resource allocation pathways of growth, defence and reproduction have rarely been assessed simultaneously nor have they been assessed across individual to landscape scales. This information is critical to identifying the physiological, environmental and genetic mechanisms underpinning resource allocation. In a recent study published in AoBP, Redmond et al. assessed trade-offs between growth, defence and reproduction among piñon...
