Global assessment of relationships between climate and tree growth

Global Change Biology, Год журнала: 2020, Номер 26(6), С. 3212 - 3220

Tree-ring records provide global high-resolution information on tree-species responses to change, forest carbon and water dynamics, past climate variability extremes. The underlying assumption is a stationary (time-stable), quasi-linear relationship between tree growth environment, which however conflicts with basic ecological evolutionary theory. Indeed, our assessment of the relevant tree-ring literature demonstrates non-stationarity in majority tested cases, not limited specific proxies, environmental parameters, regions or species. Non-stationarity likely represents general nature tree-growth proxies environment. Studies assuming stationarity score two times more citations influencing other fields science science-policy interface. To reconcile reality application for estimates, we clarification concept, propose simple confidence framework re-evaluation existing studies recommend use new statistical tool detect proxies. Our contribution meant stimulate facilitate discussion light results help increase tree-ring-based estimates science, public policymakers.

Recent studies have identified strong relationships between delayed recovery of tree growth after drought and mortality caused by subsequent droughts. These observations raise concerns about forest ecosystem services post-drought given the projected increase in frequency extremes. For quantifying impact extreme droughts on radial growth, we used a network tree-ring width data 1689 trees from 100 sites representing most distribution two tolerant, deciduous oak species (Quercus petraea Quercus robur). We first examined which climatic factors seasons control if there is any latitudinal, longitudinal or elevational trend. then quantified relative departure pre-drought during droughts, how fast were able to recover level. Our results showed that was more related precipitation water balance (precipitation minus potential evapotranspiration) than temperature. However, did not detect clear trends except decreasing influence summer Q. with latitude. Neither maintain level both rapid even compensation but displayed slow response spring where none fully growth-level over three years. Collectively, our indicate oaks are considered resilient also shown vulnerability when occurred especially at long-term significantly correlated factors. This improved understanding role seasonality climate sensitivity key better predict trajectories drier for Europe.

Large projected increases in forest disturbance pose a major threat to future wood fiber supply and carbon sequestration the cold-limited, Canadian boreal ecosystem. Given large sensitivity of tree growth temperature, warming-induced productivity have potential reduce these threats, but research efforts date yielded contradictory results attributed limited data availability, methodological biases, regional variability dynamics. Here, we apply machine learning algorithm an unprecedented network over 1 million records (1958 2018) from 20,089 permanent sample plots distributed across both Canada United States, spanning 16.5 °C climatic gradient. Fitted models were then used project near-term (2050 s time period) six most abundant species forest.

Revealing legacy effects of extreme droughts on tree growth of oaks across the Northern Hemisphere

Forests are undergoing increasing risks of drought-induced tree mortality. Species replacement patterns following mortality may have a significant impact on the global carbon cycle. Among major hardwoods, deciduous oaks (Quercus spp.) increasingly reported as replacing dying conifers across Northern Hemisphere. Yet, our knowledge growth responses these to drought is incomplete, especially regarding post-drought legacy effects. The objectives this study were determine occurrence, duration, and magnitude effects extreme droughts how that vary species, sites, characteristics. quantified by deviation observed from expected radial indices in period 1940–2016. We used stand-level chronologies 458 sites 21 oak species primarily Europe, north-eastern America, eastern Asia. found could last 1 5 years after more prolonged dry sites. Negative (i.e., lower than expected) prevalent repetitive effect was stronger Mediterranean Quercus faginea. Species-specific analyses revealed Q. petraea macrocarpa negatively affected while several mesic increased during years. Sites showing positive correlations winter temperature showed little no depression drought, whereas with correlation previous summer water balance decreased growth. This indicate although warming favors droughts, previous-year precipitation predispose trees current-year droughts. Our results massive role determining highlighted sensitivity climate, seasonality species-specific traits drive species.

Winners and losers of climate warming: Declining growth in Fagus and Tilia vs. stable growth in three Quercus species in the natural beech–oak forest ecotone (western Romania)

Global warming and increasing drought severity are exposing temperate forests to stress, challenging silvicultural decision making. Growth analyses in marginal tree populations at drought-induced range limits may provide valuable information on species' adaptive potentials species-specific climate turning points. We studied the sensitivity resilience of radial growth, long-term growth trends mesic rear-edge Fagus sylvatica comparison three oak species (Quercus petraea, Q. frainetto, cerris) Tilia tomentosa natural ecotones from beech xeric along elevation transects western Romania. Radial all was positively influenced by summer precipitation low intensity, negatively high temperatures. The basal area increment (BAI) F. T. has declined last 10–20 years with a deterioration water balance, while Quercus maintained stable rates, though lower BAI levels, suggesting negative relationship between mean resistance among five species. reductions during severe events (2000, 2003, 2012) were stronger, lower, than species, pointing thermal limit June–August temperatures 20–21 °C. As is similar predicted colline/submontane Central Europe about 50 years, decline vitality likely also drought-affected regions distribution centre future warming. Our results demonstrate that choosing stress-tolerant petraea (as well as frainetto instead more productive timber relatively safe option for European forestry warmer climate.

Increasing Winter Temperatures Stimulate Scots Pine Growth in the North German Lowlands Despite Stationary Sensitivity to Summer Drought

Abstract More than half of the forest area North German Lowlands is stocked with Scots pine-dominated forests, mostly plantations. Climate change suggests a declining suitability Europe’s temperate zone for conifer plantations, but only few studies have examined long-term growth trends pine in relation to environmental and site factors this region. We studied radial patterns over last 60 years at ten sites along precipitation gradient (830–530 mm mean annual precipitation) from an oceanic subcontinental climate, analyzing spatial temporal variability climate sensitivity identify main climatic influencing across gradient, which covers large part species’ tolerated range. Annual increment was sensitive late-winter temperatures (February, March) summer drought heat (June–August), increasing drier continental sites. Warmer periods apparently stimulated during decades, while summer-drought has remained fairly stable. Until recently, negative impact warming summers on been compensated by positive effect warming, resulting stable (or increasing) trends. However, our comparison that compensation through winter will future be limited exposure. Thus, productivity declines are likely northern lowlands despite winters, discouraging large-scale plantations face warming.
