Changing patterns of carnivore modification in a landscape bone assemblage, Amboseli Park, Kenya 总被引:2,自引:1,他引:1
This study compares the landscape-scale taphonomic signal of carnivore modification to the surficial bone assemblage in Amboseli Park, Kenya as it was in 1975 and 2002–2004. Change in predator abundances over time provides a means of assessing the taphonomic signal of carnivore-mediated bone consumption and destruction under differing ecological conditions and varying levels of conspecific competition for resources. The landscape assemblage indicates taxonomic variation in the patterning of carnivore modification to ungulates of different size classes as well as within equivalent size classes. Analyses of long bone elements indicate that the differential destruction of limb ends and the strength of the correlation between limb end abundance and bone mineral density provide an indication of the intensity of carnivore modification to a faunal assemblage. The ability to infer levels of carnivore modification based on limb elements can provide faunal analysts with the tools to determine whether the taphonomic signals in the fossil record relate to carnivore modification, hominin transport of appendicular elements, or both. 相似文献

加强地方政府之间的合作,既是公共行政改革的必然趋势,也是当今行政科学研究的热点问题。本文在分析无隶属关系地方府际关系的内涵及其竞争与合作类型的基础上,指出它们之间应建立协商合作、互相支援、互通有无、互惠互利的关系。 相似文献

随着我国计划经济体制向市场经济体制的转轨,人们的生活方式和思想观念发生了深刻的变化,从而对大众传播媒体的要求也越来越高。对于党报来说,这既意味着一种机遇,又意味着一种挑战。面对这种形势,如何进行新闻改革,如何运用新兴的科技成果为版面服务,调整经营思想以适应出版发行渠道的变化和广大受众的要求,这些都是党报必须面对的重要课题。 相似文献

论文回顾了2009年莫斯科"6·29"俄方关闭切尔基佐夫市场事件的始末,对由此引发的中俄两国民间经济、民事冲突的心理根源进行了剖析。认为2009年莫斯科切尔基佐夫批发市场的关闭,是近些年在俄罗斯频繁发生的华商经济冲突的最高潮。在中俄两国政治关系如火如荼发展、经济联系愈见紧密的同时,发生上述事件有其内在的文化、心理根源,两国差异性的民族心理与民族性格是一系列相关事件发生的内在动因。 相似文献

大都市区民宿和酒店业的空间竞争区位识别及其态势驱动力解析是实现都市旅游住宿业多业态共赢与全域可持续的重要现实条件。本文利用GIS空间分析技术和地理探测器,从微观尺度刻画上海市民宿和酒店业的空间竞争格局演化特征并探测其影响因素。研究发现:①上海市民宿业和酒店业集聚热点均趋向群集演化,民宿业历经“零星单点、单核、双核引领+郊区多组团”演化阶段且具有显著的景区指向性;酒店业历经“单核、单核强化、面状集聚+点状环绕”演化阶段且具有显著的城市商业中心指向性;②民宿业与酒店业的空间竞争程度加剧,竞争范围扩大,竞争形式由酒店业近乎垄断的空间剩余竞争发展为空间非剩余竞争和剩余竞争并存,最终形成空间竞争与错位共生并存状态。③文旅禀赋、商业设施和人口集聚是影响民宿和酒店业微观布局的主要因素,地价和交通条件的影响次之;经营理念、客群定位、经济实力以及空间载体差异是造成民宿和酒店业格局分异的隐性宏观动因。 相似文献

Abstract Osphresiology, though beginning with Aristotle, and the title of a classical monograph from 1819 by Cloquet, has, like the human sense of smell itself, played a relatively modest role, compared to other sensory functions. The anatomical and physiological connections of the nose to the brain proved to be more complex than those of sight, hearing and even touch, and were therefore poorly understood before the second half of the 19th century. Moreover, the close association between smell and taste gave rise to much controversy regarding the respective roles of the first and the fifth cranial nerves. Next, came the unfolding of the evolutionary influence of cerebral structure and function ‐ viz Broca's “limbic”; concept, and the “olfactory desert”; in the brains of “anosmatic”; animals. Jackson's “uncinate”; seizures featuring olfactory hallucinations brought the hippocampal formation into focus. Finally, there were the clinical manifestations of hyposmia and hyperosmia, from “coryza”;, the common cold, to injury or neoplasms causing hyposmia, as well as some endocrine alterations causing hyperosmia. (And let us not forget Charles Huysman's “Against the Grain”; and Marcel Proust's evocative fragrant madeleine.) 相似文献
