US-Venezuela Dissertation: Eco-Physiology and Demography of Mangroves as They Relate to Light and Salinity.

0003023 Ackerly/Hoffman该奖项将资助Laura Lopez Hoffman在斯坦福大学David Ackerly博士的指导下，与委内瑞拉西部马拉开波保护研究所的研究人员合作，获得学位论文增强补助金。研究人员将通过研究盐度和光照对两种新热带红树林的碳吸收、生长和人口统计的影响，来研究不同的环境条件如何影响植物的表现。他们将检验这样一种假设，即在低盐度和高盐度下，增加光照对红树林的影响分别是有益的和有害的。这一假说将结合斯坦福大学的温室实验和委内瑞拉的实地研究，从三个层面进行分析：叶片生理学、全株生长和种群动态。这些成果将通过生理和人口模型综合起来，预计将在生态规模、红树林恢复和可持续采伐领域作出重大贡献。

0003023Ackerly/HoffmanThis award will fund a dissertation enhancement grant for Laura Lopez Hoffman, under the direction of Dr. David Ackerly, Stanford University, in collaboration with researchers from the Instituto para la Conservacion del Lago de Maracaibo, in western Venezuela. The researchers will investigate how different environmental conditions can affect plant performance by examining the effects of salinity and light on the carbon gain, growth and demography of two species of neo-tropical mangroves. They will test the hypothesis that the effects of increasing light availability on mangroves are beneficial and detrimental at low and high salinity respectively. The hypothesis will be addressed at three levels of analysis: leaf physiology, whole plant growth, and population dynamics, using a combination of greenhouse experiments at Stanford University and field studies in Venezuela. The results will be integrated through physiological and demographic models and are expected to make significant contributions in the areas of ecological scaling and mangrove restoration and sustainable harvesting.
