The relationship between root development and drought resistance of two Eucalyptus species (Eucalyptus microtheca Muell and Eucalyptus sargentii Maiden) [PDF]
مجله جنگل ایران, 2016 Drought stress is one of the most important factors reducing the plant growth and yield. Due to the complexity of factors affecting the drought tolerance or resistance in plants and access to relevant mechanisms, researchers are faced with challenges ...

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

, 2012 Scarcity of water is a severe environmental limit to plant productivity. Drought-induced loss in crop yield probably exceeds losses from all other causes, since both the severity and duration of the stress are critical.

Drought on the Fly: UAS Mapping of Conifer Drought Stress
Forest ScienceAbstract Foliar moisture content (FMC) plays a crucial role in arid, frequent-fire forests by influencing fire behavior, tree survival, and serving as a proxy for tree health. Management actions such as mechanical thinning, flammable fuels reduction, and prescribed fires can act to mitigate wildfire risk and improve forest health by ...

American Journal of Botany, EarlyView.Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

American Journal of Botany, EarlyView.Abstract Premise In semiarid ecosystems such as the Brazilian Caatinga, physical seed dormancy (PY) is critical for plant persistence when water is unpredictable, but how soil moisture and temperature regulate PY release and seed longevity in species of native Fabaceae that have different growth forms is unknown. Methods Seeds of the herbaceous species

Hydraulic function of medullary bundles in a tropical root climber
American Journal of Botany, EarlyView.Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function in a tropical root climber, Adelobotrys scandens (Melastomataceae) to ...

National Drought Policy Commission Report
, 2000 In 1998, Congress passed the National Drought Policy Act. The Act stated that this nation would benefit from national drought policy based on preparedness and mitigation to reduce the need for emergency relief.

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species
American Journal of Botany, EarlyView.Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.
