9318099 Howard Long-term studies of natural populations, especially when combined with experimental data, produce essential information relevant to many theoretical and applied biological issues. For example, the significance of year-to- year variations in population levels cannot be evaluated properly without a database extending over considerable time intervals. Dr. Howard will conduct several types of research. He will continue long-term demographic data collection. He will also study the mechanisms animals use to choose their mates and the effects of these choices on the biological success of both males and females. The results will be important for theoretical understanding of the mechanisms and evolution of mating behavior. In addition, the resulting basic information on natural breeding behavior will help improve management programs, including captive breeding and the reintroduction of captive-bred animals to their natural habitats.

9318099 霍华德 对自然群体的长期研究，特别是与实验数据相结合，产生了与许多理论和应用生物学问题相关的重要信息。 例如，如果数据库没有延伸相当长的时间间隔，就无法正确评估人口水平逐年变化的显着性。 霍华德博士将进行多种类型的研究。 他将继续收集长期人口数据。 他还将研究动物选择配偶的机制以及这些选择对雄性和雌性生物学成功的影响。 这些结果对于从理论上理解交配行为的机制和进化非常重要。 此外，由此产生的有关自然繁殖行为的基本信息将有助于改进管理计划，包括圈养繁殖和将圈养繁殖的动物重新引入其自然栖息地。
