Top predators, particularly seabirds, have repeatedly been suggested as indicators of marine ecosystem status. One region currently under pressure from human fisheries and climate change is the North Sea. Standardized seabird monitoring data have been collected on the Isle of May, an important seabird colony in the northwestern North Sea, over the last 10-20 years. Over this period oceanographic conditions have varied markedly, and between 1990 and 1999 a major industrial fishery for sandlance (Ammodytes marinus), the main prey of most seabird species, was prosecuted nearby. Sandlance fishing grounds close to seabird colonies down the east coast of the UK were closed in 2000 in an attempt to improve foraging opportunities for breeding seabirds, particularly black-legged kittiwakes (Rissa tridactyla). Initially this closure seemed to be beneficial for kittiwakes with breeding success recovering to pre-fishery levels. However, despite the ban continuing, kittiwakes and many other seabird species in the North Sea suffered severe breeding failures in 2004. In this paper, we test the predictive power of four previously established correlations between kittiwake breeding success and climatic/trophic variables to explain the observed breeding success at the Isle of May in 2004. During the breeding season, kittiwakes at this colony switch from feeding on 1+ group to 0 group sandlance, and results up until 2003 indicated that availability of both age classes had a positive effect on kittiwake breeding success. The low breeding success of kittiwakes in 2004 was consistent with the late appearance and small body size of 0 group sandlance, but at odds with the two variables likely to operate via 1 group availability (lagged winter sea surface temperature and larval sandlance cohort strength in 2003). The reason for the discrepancy is currently unknown, but analysis of 1 group sandlance body composition indicated that lipid content in 2004 was extremely low, and thus fish eaten by kittiwakes during pre-breeding and early incubation were likely to be of poor quality. Monitoring of reproductive success of kittiwakes, although useful, was clearly not sufficient to tease apart the complex causation underlying the 2004 event. Monitoring programs such as this, therefore, need to be complemented by detailed research to identify the mechanisms involved, and to attribute and predict the effects of natural and human-induced environmental change.  相似文献

北京大学的综合自然地理学缘起于1952年全国院系调整时在本校设置的自然地理学学科,在半个多世纪的发展历程中,经历了学科初创和完善等阶段,逐渐形成了面向学科前沿和国家需求的综合自然地理学学科体系。针对日趋严峻的气候变化、资源环境和社会经济发展问题,北京大学综合自然地理学在陆地表层过程及机理、土地利用/覆被变化及其生态环境效应、生态系统服务与人类福祉、生态风险评价与安全格局构建、自然地域系统划分等方面进行了开拓创新,取得了丰硕成果,引领了中国综合自然地理学的发展。展望未来,北京大学综合自然地理学将持续进行水、土、气、生等自然地理要素与过程的综合研究,认识人类活动与全球环境变化对主要自然地理过程和格局的影响机理,通过构建观测数据与地表系统模型融合系统,定量评估要素与过程耦合的区域资源环境效应及其对社会经济的影响,在生态文明建设、主体功能区划、国土开发整治和流域综合管理等国家战略服务方面做出更大贡献。  相似文献

Over the past three decades, feminist historiography of geography has begun to situate women's contribution to the production of geographical knowledge within the histories of geography, at times against the conviction of skeptical colleagues. In this Focus Section introduction, we renew Domosh's (1991a Domosh, M. 1991a. Beyond the frontiers of geographical knowledge. Transactions of the Institute of British Geographers 16 (4): 48890.[Crossref], [Web of Science ®] [Google Scholar], 1991b ———. 1991b. Toward a feminist historiography of geography. Transactions of the Institute of British Geographers 16 (1): 95104.[Crossref], [Web of Science ®] [Google Scholar]) call for creating more inclusive feminist histories of geography by situating the three focus section articles on the careers and contributions of women in twentieth-century geographical practice and knowledge production in the United Kingdom and the United States within wider debates about diverse, unfamiliar, and previously hidden aspects of geographical knowledge production. We argue that feminist historiography of geography and feminist historical geography could benefit from continuously diversifying inclusive and comparative research perspectives, and from unlocking diverse archives, to enhance understanding of why and how some male and some female gatekeepers have been more supportive of women than others.  相似文献

The article presents a systematic review of 152 articles in which the concept of knowledge is applied and that are published in international human geography journals. As the importance of knowledge in society is increasing, especially economic geography has taken up the task of reviewing the concept or role of knowledge in geography. However, there is a need for a more nuanced understanding of knowledge in economic geography, drawing more broadly on human geographical research. The authors analyse how the concept of knowledge is understood and applied in contemporary human geography. Their results demonstrate four knowledge rationales: economic, policy, empowerment, and methodological. Each rationale and their combinations display a particular role and purpose for knowledge, as well as a distinct approach to space. Separately, each rationale provides several insights into a more nuanced understanding of specific aspects of knowledge. When combined, the four rationales offer a holistic overview of the field. The authors conclude that the empowerment rationale offers novel methodological choices towards a more nuanced understanding of knowledge in economic geography.  相似文献

This article reconstructs the history, organization, and campaigning function of the Geographical Circle of the Lyceum Club—a membership group that, under the leadership of Bessie Pullen-Burry (1858–1937), sought to promote and legitimize women's geographical work in early twentieth-century Britain. Through an examination of archival material and contemporary press coverage, I document the Geographical Circle's efforts to establish itself as a professional body for women geographers and to lobby for their admission to the Royal Geographical Society. Although considerable scholarly attention has been paid to women geographers’ individual contributions to the discipline, their cooperative, professionalizing endeavors have been comparatively neglected. In tracing the parallel history of the Circle as an example of women's self-organization, and of Pullen-Burry as an independent campaigner, I argue that a nuanced account of women's professionalization in geography demands attention to both individual and collective endeavors.  相似文献
