The decline of perennial plant species, including oak, olive, and kiwifruit, is a phenomenon currently observed in many areas the world. In this review, such species are chosen precisely because, despite differences their botany, native distribution, current utilization, they all affected by significant global or local declines. An analysis main common causes involved could be useful for better understanding phenomenon. Quercus impacted “Chronic Oak Decline” (COD), “Sudden (SOD), “Acute (AOD). Italy, olive groves severely damaged “Olive Quick Decline Syndrome”, whereas kiwifruit orchards struck “Kiwifruit Vine Syndrome” (KVDS). Among abiotic inciting stressors, drought, warmer temperatures, waterlogging, within climate change scenario, declines described herein as well dysbiosis. involvement some aggressive phytopathogens another feature these Oomycetes contribute to COD, SOD, KVDS; Xylella fastidiosa subsp. pauca Botryosphaeriaceae affect enterobacteria AOD, representing decisive contributing factors. These quite complex, comprehensive approach required dissect facets involved. A altered host–microbial community relationships can lead more tailored managing Maintaining tree resilience Earth remains primary goal achieve preserving both natural ecosystems profitable crops.

Climate change influences forest ecosystems in several ways, such as modifying growth or ecosystem functionality. To fully understand the impact of changing climatic conditions on it is necessary to undertake long-term spatiotemporal analyses. The main purpose this work describe major trends tree Pinus pinaster Spain over last 70 years, differentiating homogeneous ecological units using an unsupervised classification algorithm and additive modelling techniques. We also aim relate these with temporal series for precipitation temperature, well variables. leverage information from a large data set cores (around 2200) extracted during field campaign Fourth Spanish National Forest Inventory. classified plots into five classes, which were consistent terms. found general decline three ecoregions since 1970s, concomitant increase temperature reduction precipitation. However, has not been observed Atlantic influenced ecoregion, where cooler, more humid are stable. Certain stand features, low basal area through management practices, may have alleviated harsh some areas inner Spain, while denser stands display pronounced growth. concluded that Southern populations show degrees Northern did exhibit largest rates. Under forecasted increment temperatures, can be expanded.

Lack of management, land-use changes, poor site conditions and drought contribute to the decline of old pollarded oaks

Dendrochronologia, Journal Year: 2024, Volume and Issue: 86, P. 126232 - 126232

In Europe, people have managed forests and woodlands for centuries. Old pollarded oaks reflect historical legacies, their conservation is threatened by the abandonment of this traditional forest use. However, site conditions (topography, soil features, land cover, use) warming-triggered drought stress also contribute to growth decline, particularly in seasonally dry regions. We investigated two stands Mediterranean (Quercus subpyrenaica), where pollarding was abandoned 1950s, showing contrasting cover tree sizes north-eastern Spain. Changes characteristics (texture, pH, nutrient concentrations), climate conditions, tree-ring data (basal area increment −BAI−, ring-width indices) were analysed. The Artosilla site, smallest trees, presented lowest long-term rates (period 1730−2022, mean BAI = 19.7 cm2 yr−1) as compared with Aineto bigger (mean 32.9 yr−1). trees found both sites ages ranging 293−311 years. less fertile soils Artosilla, pine plantations diminish canopy thermal amplitude, may decline observed there. Moreover, more major suppressions 1940s, which suggest a intensive showed stronger since could be response increasingly warmer drier summer conditions. contrast, decoupling from atmospheric suggesting chronic stagnation. Poor (steeper slope, soils, contributed oaks. Active management required preserve these unique old, monumental trees.

A decade of rain exclusion in a Mediterranean forest reveals trade-offs of leaf chemical defenses and drought legacy effects

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Oct. 15, 2024

Increasing aridity in the Mediterranean region will result longer and recurrent drought. These changes could strongly modify plant defenses, endangering tree survival. We investigate response of chemical defenses from central specialized metabolism Quercus pubescens Willd. to future drought using a long-term experiment natura where trees have been submitted amplified (~ –30% annual precipitation) since April 2012. focused on leaf metabolites including chlorophylls carotenoids (central metabolism) flavonols (specialized metabolism). Measurements were performed summer 2016 2022. Amplified led higher concentrations total photosynthetic pigments over 2016–2022 period. However, it also lower AZ/VAZ flavonol concentrations. Additionally, Q. responded previous precipitation low 1 year and/or 2 years preceding sampling was associated VAZ, high neoxanthin Our study indicates that decline concentration under is counterbalanced by production several metabolites. Such results are potentially due an adjustment metabolism, highlighting importance performing experimental studies for assessing legacy effects thus forest adaptation climate change.
