Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Precipitation Processes

The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Adaptations that Reduce Water Loss

26.8K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Heat and Cold Stress

14.0K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Global Climate Change

25.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Regulation of Transpiration by Stomata02:04

Regulation of Transpiration by Stomata

29.4K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Área de la Ciencia:

  • Ciencias del clima
  • Física de la atmósfera
  • Ciencias del sistema terrestre

Sus antecedentes:

  • Los climas de invernadero se caracterizan por el calentamiento radiativo de la troposfera inferior, a diferencia del enfriamiento típico.
  • Los modelos anteriores no pudieron resolver los movimientos a escala convectiva, dejando el comportamiento atmosférico del invernadero mal entendido.

Objetivo del estudio:

  • Para investigar la dinámica atmosférica en estados climáticos de invernadero.
  • Comprender las implicaciones del calentamiento radiativo de la troposfera inferior en el ciclo hidrológico y la cubierta de nubes.

Principales métodos:

  • Simulaciones climáticas realizadas que resuelven explícitamente la convección.
  • Analizó el comportamiento del ciclo hidrológico y la cubierta de nubes en condiciones simuladas de invernadero.

Principales resultados:

  • Identificó un cambio en el ciclo hidrológico de un estado casi estacionario a un régimen de "oscilador de relajación".
  • Se han observado intensos estallidos de precipitación separados por períodos de sequía.
  • Encontró flujos de precipitación local mejorados, mayor cobertura de nubes y un parámetro de retroalimentación climática transitoriamente inestable.

Conclusiones:

  • Los climas de invernadero pueden exhibir una autoorganización convectiva "temporal".
  • Estos hallazgos tienen implicaciones para la dinámica de las nubes y los procesos de erosión en climas extremadamente cálidos.
