This award continues funding the long-term research program in aridland ecology. The research is to understand how the physical environment and climate variability together affect common species, community dynamics and ecosystem processes in the northern Chihuahuan Desert. The Sevilleta LTER Program addresses ecological concepts and theory emphasizing pulse driven processes in space and time through comprehensive and interdisciplinary research in desert grassland, shrubland, forest and riparian habitats in central New Mexico. Through a combination of long-term measurements, experiments, and modeling, the research considers how climate and the physical environment interact to effect change in aridland ecosystems. The focal sites are the Sevilleta National Wildlife Refuge and the Middle Rio Grande Basin. The Sevilleta LTER support our Schoolyard LTER program, the Bosque Ecosystem Monitoring Program, reaches hundreds of middle and high school students annually in classroom and outdoor settings. The Arts and Ecology REU Program brings together students from fine arts and ecology for an 11-week summer research and creative experience. LTER scientists and students actively participate in the Ecological Society of America?s SEEDS Program by hosting workshops and mentoring SEEDS Fellows. The Sevilleta LTER participates in the newly developed Junior Scientist Outreach Program, a program sponsored by the Biology Department at the University of New Mexico, which targets underserved Hispanic students in Albuquerque's south valley. Activities include organized visits to the campus, summer field camps, and active participation in field research.

该奖项继续资助干旱地区生态学的长期研究计划。该研究旨在了解物理环境和气候变化如何共同影响北方奇瓦瓦沙漠的常见物种、群落动态和生态系统过程。Sevilleta LTER计划通过对新墨西哥州中部沙漠草原，灌木丛，森林和河岸栖息地的全面和跨学科研究，解决生态概念和理论，强调空间和时间的脉冲驱动过程。通过长期测量、实验和建模相结合，该研究考虑了气候和物理环境如何相互作用以影响干旱地区生态系统的变化。重点地点是塞维利亚国家野生动物保护区和中格兰德河盆地。塞维利亚LTER支持我们的校园LTER计划，博斯克生态系统监测计划，每年在教室和户外环境中接触数百名初中和高中学生。艺术与生态REU计划汇集了来自美术和生态学的学生，进行为期11周的夏季研究和创造性体验。LTER的科学家和学生积极参与美国生态学会？的种子计划主办讲习班和指导种子研究员。塞维利亚LTER参加了新开发的初级科学家外展计划，这是一个由新墨西哥州大学生物系赞助的计划，目标是阿尔伯克基南部山谷服务不足的西班牙裔学生。活动包括有组织地参观校园，夏令营，并积极参与实地研究。
