Insights from full-rotation Nelder spacing trials with Eucalyptus in São Paulo, Brazil (2010, background): “The causes of declines in forest growth as relatively young forests increase in age is a topic of great research interest (Gower et al. 1996, Ryan et al. 2004, 2010, Stape et al. 2010).”
Late-summer carbon fluxes from Canadian forests and peatlands along an east-west continental transect (2006, methodology): “An experimental test with Eucalytpus plantations in Hawaii indicated that GPP declined with stand age, whereas the belowground allocation of GPP and the fraction partitioned to foliar respiration increased (Ryan et al. 2004).”
Partitioning of net primary production in Eucalyptus and Acacia stands and in mixed-species plantations: Two case-studies in contrasting tropical environments (2013, background): “As expected from this concept, the amount of C allocated to belowground production (BNPP) shifts toward aboveground production (ANPP), and especially wood production (wood NPP), with increasing soil fertility (Keith et al., 1997; Ryan et al., 2004; Litton et al., 2007; Campoe et al., 2012; Epron et ”
Explaining growth of individual trees: Light interception and efficiency of light use by Eucalyptus at four sites in Brazil (2010, background): “For example, Ryan et al. (2004) found that gross primary production declined by one-third from midrotation to late-rotation in a plantation of Eucalyptus saligna despite sustained high rates of resource supply and use; wood production dropped by more than half.”
Influence of competition and age on tree growth in structurally complex old-growth forests in northern Minnesota, USA (2013, background): “Whether these effects are due to tree size rather than age has been debated, and the exact mechanisms governing the age-related reductions in tree growth remain elusive (Li et al., 2012; Mencuccini et al., 2005; Ryan et al., 2004).”
Aging in Perennials (2007, background): “Measuring water relations, gas exchange and the growth of eucalyptus for over 6 years, Ryan et al. (2004) found that the older, 25-m trees grew much more slowly and showed lower photosynthetic rates than the youngest ones, but also that water was too plentiful to be the cause.”
Climate and competition effects on tree growth in Rocky Mountain forests (2017, background): “Current hypotheses describe processes that cause progressive increases in physiological stress over time, including continuous increases in respiration demand in accumulating tissues and hydraulic limitations associated with increasing stem height (Ryan et al. 2004).”
The hydraulic limitation hypothesis revisited. (2006, methodology): “Only one experiment (Barnard & Ryan 2003; Ryan et al. 2004) explicitly linked physiological tests of HLH with tree or stand growth.”
Scaling from individual trees to forests in an Earth system modeling framework using a mathematically tractable model of height-structured competition (2015, background): “Studies have also found that the ratio of autotrophic respiration to GPP is independent of age (Ryan et al., 2004), which is consistent with our model.”
Factors controlling Eucalyptus productivity: How water availability and stand structure alter production and carbon allocation (2010, methodology): “Ryan et al. (2004) found no change in fine root biomass after canopy closure and that fine root biomass (<2 mm diameter in their study) was less than 5% of the total root biomass for Eucalyptus in Hawaii.”
Age‐related decline of stand biomass accumulation is primarily due to mortality and not to reduction in NPP associated with individual tree physiology, tree growth or stand structure in a Quercus‐dominated forest (2012, background): “In particular, the link between hydraulic limitation of carbon assimilation and tree growth is rarely studied (n.b. Barnard & Ryan 2003; Ryan et al. 2004).”
A review of light interception in plant stands from leaf to canopy in different plant functional types and in species with varying shade tolerance (2010, background): “8, King 2003) varies significantly among woody species, likely providing explanation for species differences in age-dependent modifications in foliage biomass and L observed across the studies (e.g., Ryan et al. 1997, 2004).”
Below‐ground carbon flux and partitioning: global patterns and response to temperature (2008, background): “For example, there are eight data points at 21 °C with GPP values ranging from 2369 to 5561 g C m−2 year−1 that represent 2 and 6 year-old stands that varied in density and nutrient supply treatments for a single species planted at the same site (Eucalyptus saligna plantations in Hawaii; Ryan et al.”
