Response of Pedunculate Oak (Quercus robur L.) to Adverse Environmental Conditions in Genetic and Dendrochronological Studies

Plants, Journal Year: 2025, Volume and Issue: 14(1), P. 109 - 109

Published: Jan. 2, 2025

Pedunculate oak (Quercus robur L.) is widely distributed across Europe and serves critical ecological, economic, recreational functions. Investigating its responses to stressors such as drought, extreme temperatures, pests, pathogens provides valuable insights into capacity adapt climate change. Genetic dendrochronological studies offer complementary perspectives on this adaptability. Tree-ring analysis (dendrochronology) reveals how Q. has historically responded environmental stressors, linking growth patterns specific conditions drought or temperature extremes. By examining tree-ring width, density, dynamics, researchers can identify periods of suppression enhancement predict forest future climatic events. further complement by uncovering adaptive genetic diversity inheritance patterns. Identifying markers associated with stress tolerance enables managers prioritize the conservation populations higher potential. These guide reforestation efforts support development climate-resilient populations. integrating data, gain a holistic understanding robur’s mechanisms resilience. This knowledge vital for management sustainable planning in face challenges, ultimately helping ensure long-term viability their ecosystems. The topics covered review are very broad. We tried include most relevant, important, significant studies, but focused mainly relatively recent Eastern European because they species’ area. However, although more than 270 published works have been cited review, we have, course, missed some studies. apologize advance authors those relevant that not cited.

Dating the Noah trees to improve age estimates in centennial and millennial olive trees

Dendrochronologia, Journal Year: 2024, Volume and Issue: 84, P. 126181 - 126181

Published: Feb. 21, 2024

The olive tree is an iconic component of Mediterranean agricultural landscapes. Many monumental trees are regarded as millennial individuals, but their ages cannot be estimated through ring dating. Alternatively, 14C-dating pith wood sample provides age estimates for these old trees. However, published indicate that most range between 200 and 700 years. Nevertheless, some rare individuals may or even older. Here we report the oldest dated tree, sampled in so-called Noah grove Bshaaleh (northern Lebanon), having 1161 ± 131 years according to 14C By measuring diameter, counting, dating countries equation was obtained estimate 14C-estimated trees: = 37.56 + 1.835 diameter. We conclude centennial not millennial, with very probably restricted harsh sites where show slow growth rates.

Sudden disappearance of yew (Taxus baccata) woodlands from eastern England coincides with a possible climate event around 4.2 ka ago

Quaternary Science Reviews, Journal Year: 2023, Volume and Issue: 323, P. 108414 - 108414

Tree-ring chronologies form the backbone of high-resolution palaeoclimatology. However, their number declines drastically prior to medieval times, and only a few such records worldwide extend back mid-Holocene. Here, we present collection more than 400 subfossil yew (Taxus baccata L.) trees excavated from near sea-level peat-rich sediments in Fenland region eastern England. The well-preserved trunks are between two eight metres long, often exhibit adventitious root layers, contain up rings highly irregular growth. Combined dendrochronological radiocarbon dating resulted tree-ring width that comprise 36 32 trees, span 413 418 years, mean inter-series correlations (Rbar) 0.50 0.51, were provisionally dated 5225−4813 (±4) 4612−4195 (±6) years cal BP.
