The limits to tree height
Redwoods are studied, including the tallest known tree on Earth, in wet temperate forests of northern California, to estimate a maximum tree height of 122–130 m barring mechanical damage, similar to the tallest recorded trees of the past.
Convergence across biomes to a common rain-use efficiency
It is shown that RUE decreases across biomes as mean annual precipitation increases, and during the driest years at each site, there is convergence to a common maximum RUE (RUEmax) that is typical of arid ecosystems.
Responses of terrestrial ecosystems to temperature and precipitation change: a meta‐analysis of experimental manipulation
Global mean temperature is predicted to increase by 2–7 °C and precipitation to change across the globe by the end of this century. To quantify climate effects on ecosystem processes, a number of…
Pervasive drought legacies in forest ecosystems and their implications for carbon cycle models
P pervasive and substantial “legacy effects” of reduced growth and incomplete recovery for 1 to 4 years after severe drought were found, most prevalent in dry ecosystems, among Pinaceae, and among species with low hydraulic safety margins.
Plants actively control nitrogen cycling: uncorking the microbial bottleneck.
It is stressed that under many circumstances plant species exert a major influence over soil N cycling rates via unique N attainment strategies, thus influencing soil N availability and their own fitness.
Recovery of ponderosa pine ecosystem carbon and water fluxes from thinning and stand‐replacing fire
The results show large and persistent effects of intense fire and minor and short-lived effects of thinning on southwestern ponderosa pine ecosystem carbon and water exchanges.
Global patterns of drought recovery
This analysis of three independent datasets of gross primary productivity shows that, across diverse ecosystems, drought recovery times are strongly associated with climate and carbon cycle dynamics, with biodiversity and CO2 fertilization as secondary factors.
Effect of temperature on metabolic activity of intact microbial communities: Evidence for altered metabolic pathway activity but not for increased maintenance respiration and reduced carbon use…
Hydrostatic constraints on morphological exploitation of light in tall Sequoia sempervirens trees
The results suggest that hydrostatic limitation of morphological development constrains exploitation of light in the upper crown and contributes to reduced photosynthetic rates and, ultimately, reduced height growth at the tops of tall S. sempervirens trees.
Long‐term impact of a stand‐replacing fire on ecosystem CO2 exchange of a ponderosa pine forest
Ponderosa pine (Pinus ponderosa) forests of the southwestern United States are a mosaic of stands where undisturbed forests are carbon sinks, and stands recovering from wildfires may be sources of…
