Stream Nitrogen Responses to Fire
Fire can play a sigdicant role in runoff, sediment yield, and nitrate transport in aquatic and terrestrial ecosystems in the southeast US. The typical impact of fire is an immediate change in the physical properties of the soil and forest floor surface, followed by midand long-term changes in biological pools and cycling processes. Depending upon the severity of the fire and p b u r n condition...
متن کاملPrediction Driven Behavior: Learning Predictions that Drive Fixed Responses
We introduce a new method for robot control that combines prediction learning with a fixed, crafted response—the robot learns to make a temporally-extended prediction during its normal operation, and the prediction is used to select actions as part of a fixed behavioral response. Our method is inspired by Pavlovian conditioning experiments in which an animal’s behavior adapts as it learns to pr...
متن کاملPhysiological responses of ponderosa pine in western Montana to thinning, prescribed fire and burning season.
Low-elevation ponderosa pine (Pinus ponderosa Dougl. ex. Laws.) forests of the northern Rocky Mountains historically experienced frequent low-intensity fires that maintained open uneven-aged stands. A century of fire exclusion has contributed to denser ponderosa pine forests with greater competition for resources, higher tree stress and greater risk of insect attack and stand-destroying fire. A...
متن کاملTranscriptomic Changes Drive Physiological Responses to Progressive Drought Stress and Rehydration in Tomato
Tomato is a major crop in the Mediterranean basin, where the cultivation in the open field is often vulnerable to drought. In order to adapt and survive to naturally occurring cycles of drought stress and recovery, plants employ a coordinated array of physiological, biochemical, and molecular responses. Transcriptomic studies on tomato responses to drought and subsequent recovery are few in num...
متن کاملAbrupt increases in Amazonian tree mortality due to drought-fire interactions.
Interactions between climate and land-use change may drive widespread degradation of Amazonian forests. High-intensity fires associated with extreme weather events could accelerate this degradation by abruptly increasing tree mortality, but this process remains poorly understood. Here we present, to our knowledge, the first field-based evidence of a tipping point in Amazon forests due to altere...
