Dietary generalism is widely associated with ecological flexibility, but the mechanisms of this relationship remain poorly understood. A recent body of theory concerning the relationship between generalism/specialism at the levels of foods selected vs. nutrients ingested, termed multi-level dietary niche theory, offers powerful opportunities for furthering the understanding of the dietary generalist-specialist spectrum. We applied this framework in an intensive and extensive study of food selection and nutrient regulation responses to natural resource variation by the most ecologically generalist non-human primate, the rhesus macaque(Macaca mulatta), which is also the only species thus far identified in the wild to show a pattern of macronutrient regulation predicted on theoretical grounds to be associated with ecological generalism. We used full-day individual animal follows over 17 successive seasons to examine the patterns of resource variation and the macaques’ responses to these at the levels of food selection and patterns of macronutrient intake. We additionally analysed seasonal availability over 10 years of the keystone resource, fat-and carbohydrate-rich acorns. Our results showed that the generalist mode of macronutrient regulation is not associated with exploitation of many different foods, as previously predicted, but with few foods that vary widely in their macronutrient composition and fluctuate predictably in their relative availability across seasons and across alternate years. We integrate these results with energy budgets and literature data to build a verbal model of how the generalist pattern of macronutrient regulation interfaces between nutritional physiology and resource variability to buffer rhesus macaques from broad climatic fluctuations.

人与野生动物冲突是全世界自然保护工作所面临的最大挑战之一。为降低这些冲突的影响,各国采取了各种保护策略,但这些策略常常得不到足够的监测,其效力也得不到充分的评估。近年来,作为降低人与野生动物冲突的一项措施,尼泊尔各保护区周围建起了电篱笆。到目前为止,未见有其他针对保护工作中采用电篱笆的成本效率及其功效开展分析的研究。本研究的目的是检验尼泊尔近年来设立于旺国家公园东区的电篱笆的成本效率。印度犀牛(Rhinoceros unicornis)、野猪(Sus scrofa)、亚洲象(Elephas maximus)、老虎(Panthera tigris)是该国家公园周边缓冲区涉及人与野生动物冲突的主要物种,这里建有电篱笆。电篱笆使庄稼受损减少78%,家畜损失减少30%-60%。研究区的人类死亡数未表现出显著下降,而是继续维持较低数值。我们的分析表明,至2009/2010财政年度,电篱笆成本的总净现值,卡根社区(KMUC)为1 517 959尼泊尔卢比(21 685美元),姆瑞加社区(MKUC)为3 530 075卢比(50 429美元);而净现收益,卡根社区为16 301 105卢比(232 872美元),姆瑞加社区为38 304 602卢比(547 208美元)。至2009/2010基准财政年度,电篱笆的成本-效益比率,卡根社区为10.73,姆瑞加社区为10.85。这些结果表明,在大型哺乳动物出没的保护区周围,电篱笆计划在降低人与野生动物冲突方面,既有经济效益,又有很好的社会效益。

Multi-objective Genetic Optimization for LCLS-II X-ray FEL

引用

Journal of Mechanics Engineering and Automation 2014年第8期4卷 632-638页

作者： Lanfa Wang Tor O. raubenheimer SLAC (Stanford Linear Accelerator Center) Stanford University California 94025 USA

The LCLS-II (linac coherent light source II) will build on the success of the world"s most powerful X-ray laser: the LCLS (linac coherent light source). It will add two new X-ray laser beams and room for additional new instruments, thus greatly increasing the number of experiments carried out each year. Multiple operation modes are proposed to accommodate a variety of user requirements. There are a large number of variables and objectives in the design. For each operation mode, MOGA (multi-objective genetic algorithm) is applied to optimize the machine parameters in order to minimize the jitters, energy spread, collective effects and emittance.
