Abstract Under global warming, drought will reduce productivity of Pinus halepensis s.l. (subspecies and brutia ) cause a retreat from its rear edge distribution (latitudinal/elevational) in the Mediterranean. To test whether topography can influence this scenario, we studied for approximately 40 years growth six natural pine stands water-limited habitats on islands Zakinthos Samos (eastern Mediterranean Greece), determined critical moisture sources that drove growth. Dominant pines were selected with no permanent water under contrasting conditions created by (“wet”-gulley/valley vs. “dry”-upslope habitats). The responses P. to moderate worst case scenario tested, projected warming (approx. − 25% 40% annual precipitation compared 1961–1990 average). Our results show “wet” habitat had higher normal wet climate. However, more declined, tree was reduced at significantly faster rate, but also showed recovery, once rainfall returned. Thus, populations gullies/valleys, may be resilient less likely towards elevation/latitudes dry upslope sites. drought, both ecosystems relied deeper pools supplied previous 3–6 (including year growth). valley/gully soils (and probably heavily weathered bedrock), appeared utilize surface winter/spring efficiently survival recovery. deep provide key “buffer” such could act as potential refugia climate change.

Abstract In Tianluoshan site, a comprehensive analysis was conducted using suite of scientific methods, including scanning electron microscopy, Fourier transform infrared spectroscopy, and X‐ray diffraction. The addressed prevalent issues within the earthen site condition criticalities, such as surface weathering, cracking, microbial damage, damage by plants. results reveal that weathering is concentrated in southeast region, whereas predominates northwest. Cracking plant are less common. Surface can progress to cracking dry areas moist areas, eventually leading damage.

Permafrost melting due to climate warming in recent decades has produced significant effects on forest ecosystems, especially the boreal biome at its southernmost limit Asia. How this affects wood formation of trees intra-annual resolution is unclear, yet crucial for assessing impact permafrost growth. In study, we compared radial growth and density fluctuations (IADFs) Dahurian larch (Larix gmelinii Rupr.) a (PF) non-permafrost (NPF) site northeast China quantified their relationships with factors. Drought early summer was main factor limiting larch. The basal area increment (BAI) both sites increased initially then decreased 1980s, probably response warm-dry conditions. Earlywood IADFs (IADF-E) occurred 14.0% 9.3% dated rings NPF PF sites, while frequency latewood (IADF-L) 6.8% 2.7% these two sites. IADF-E positively negatively related June temperatures (and vapor pressure deficit) precipitation, respectively, suggesting drought stress triggered IADF-E. IADF-Ls were formed warm late growing season. A higher BAI lower IADF-Es than indicated that could alleviate promote This greatly improved carbon sequestration quality some northeastern Asian forests may offset extent adverse warming-drying climates Larch recorded extreme droughts summer, giving us new sight reconstructing high-frequency events. If continues, benefits will gradually disappear even turn negative warmer-dryer Our findings provide valuable information management conservation under future global warming.

Forests and scrubland comprise a large proportion of terrestrial ecosystems and, due to the long lifespan trees shrubs, their capacity grow store carbon as lasting woody tissues is particularly sensitive warming-enhanced drought occurrence. Climate change may trigger transition from forests in many drylands during coming decades higher resilience shrubs. However, we lack standardized frameworks compare response plants. We present framework develop an index estimate drought-induced vulnerability (DrVi) shrubs based on radial growth trajectory variability index. used tree-ring width series three tree (Pinus halepensis Mill., Juniperus thurifera L., Acer monspessulanum L.) shrub (Juniperus oxycedrus Pistacia lentiscus Ephedra nebrodensis Tineo ex Guss.) species semi-arid areas test this framework. compared DrVi values between populations explored temporal changes. Across species, strongest were found declining P. stands J. same site, while lowest A. monspessulanum, lentiscus, E. nebrodensis. populations, presented one dry sites. The stand showed steady increase value after 1980s climate shifted toward warmer drier conditions. conclude that allows comparing using general
