Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought

Plant, Cell &Environment, Volume 49, Issue 8, Page 4850-4871, August 2026.
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.

Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

Plant Biology, Volume 28, Issue 5, Page 1315-1329, August 2026.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Drought-related root morphological traits and non-structural carbohydrates in the seedlings of the alien Quercus rubra and the native Quercus robur: possible implication for invasiveness

Frontiers in Forests and Global Change
Quercus rubra L. is a moderately shade-tolerant tree species native to eastern North America, readily regenerating since its introduction in the Central and Southern European forests to displace the native pedunculate oak (Quercus robur).

Assessment of carbon and nitrogen stocks in soil and soil organic matter fractions in an alley cropping system under a northern temperate climate

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Alley cropping, combining tree rows with wide alleys for agricultural crops, has demonstrated variable potential to store additional carbon (C) and nitrogen (N) in soil, compared to conventional cropping. Studies quantifying C and N in particulate organic matter (POM) and mineral‐associated organic matter (MAOM) are scarce, despite their ...

Mycorrhizal legacy mediates seedling success following timber harvesting in Northeastern forests

Ecological Applications, Volume 36, Issue 5, July 2026.
Abstract Overstory trees rely on arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi for establishment and growth. However, we know very little about how timber harvesting affects the biotic (e.g., mycorrhizal fungi) and abiotic (e.g., nutrient availability) legacies left behind by AM and EcM trees.

Tree regeneration trends in forests of the northeastern USA and their implications for resilience and restoration

Ecological Applications, Volume 36, Issue 5, July 2026.
Abstract Tree regeneration is vital to shaping characteristics of future forests, including vulnerability to climate change; resilience to pests, pathogens and disturbance; and departure from historical species composition. We used data from nationwide forest inventory plots to investigate trends in sapling abundance and recruitment as well as tree ...

Climate‐Driven Range Shifts Limit the Role of Non‐Native Trees for Adaptation Processes of European Forests

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Ensemble species distribution model based study indicates a limited role of non native tree species as alternatives to vulnerable native tree species in Europe. ABSTRACT Climate change threatens biodiversity and ecosystem services by reducing the suitability of many native tree species in Europe.

The role of microclimate in determining the sensitivity ofQuercus rubraL. to ozone [PDF]

New Phytologist, 1994
summaryMicroclimate has been suggested as a factor to consider when scaling ozone responses of forest trees from the seedling to tree level. To test whether microclimate influences the response of seedlings to ozone. 1‐yr‐oldOuercus rubraL, seedlings were grown in the shaded upper or lower canopy of 31‐yr‐old trees in open‐top tree chambers, or in more
