The dark side of fungal competition and resource capture in wood: Zone line spalting from science to application

open access: yesMaterials & Design, 2021
On wood surfaces and in planar section, zones lines appear as narrow and sharply delineated dark lines within wood visibly altered (“spalted”) by the decay process. In intact wood, zone lines define an irregular volume of decaying wood.

Characterizing the climatic niche of mast seeding in beech: Evidences of trade-offs between vegetation growth and seed production

open access: yesEcological Indicators, 2021
Masting is a complex mechanism which is mainly driven by a combination of internal plant resources and climatic conditions. While the driving role of climate in masting is being intensively studied, the interplay among climate, seed production ...

Foliar application of glycine betaine to ameliorate lead toxicity in barley plants by modulating antioxidant enzyme activity and biochemical parameters

open access: yesEnvironmental Research Communications, 2023
Lead (Pb) toxicity is a major problem in agricultural soil that negatively affects plant growth and development. Glycine betaine (GB) is an effective compatible solute that resists abiotic stress and plays an important role to mitigate various stresses ...

Snow tussocks, chaos, and the evolution of mast seeding [PDF]

open access: yes, 2002
One hitherto intractable problem in studying mast seeding (synchronous intermittent heavy flowering by a population of perennial plants) is determining the relative roles of weather, plant reserves, and evolutionary selective pressures such as predator ...

Regeneration in gap models: priority issues for studying forest responses to climate change [PDF]

open access: yes, 2001
Recruitment algorithms in forest gap models are examined with particular regard to their suitability for simulating forest ecosystem responses to a changing climate. The traditional formulation of recruitment is found limiting in three areas.

Masting by Eighteen New Zealand Plant Species: The Role of Temperature as a Synchronizing Cue [PDF]

open access: yes, 2002
Masting, the intermittent production of large flower or seed crops by a population of perennial plants, can enhance the reproductive success of participating plants and drive fluctuations in seed-consumer populations and other ecosystem components over ...

Coordination of Foliar and Wood Anatomical Traits Contributes to Tropical Tree Distributions and Productivity along the Malay-Thai Peninsula [PDF]

open access: yes, 2009
Drought is a critical factor in plant species distributions. Much research points to its relevance even in moist tropical regions. Recent studies have begun to elucidate mechanisms underlying the distributions of tropical tree species with respect to ...
