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.

0003023阿克利/霍夫曼该奖项将资助劳拉洛佩斯霍夫曼的论文增强补助金，在斯坦福大学的大卫阿克利博士的指导下，与委内瑞拉西部马拉开波湖保护研究所的研究人员合作。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增益，生长和人口统计的影响，研究不同的环境条件如何影响植物的表现。 他们将检验这一假设，即增加光照对红树林的影响分别在低盐度和高盐度下是有益的和有害的。这一假设将在三个层次的分析：叶生理学，整个植物的生长和人口动态，结合使用温室实验在斯坦福大学和委内瑞拉的实地研究。研究结果将通过生理和人口模型加以综合，预计将在生态缩放、红树林恢复和可持续采伐方面作出重大贡献。
