Abstract: Conservation actions need to account for and be adapted to address changes that will occur under global climate change. The identification of stresses on biological diversity (as defined in the Convention on Biological Diversity) is key in the process of adaptive conservation management. We considered any impact of climate change on biological diversity a stress because such an effect represents a change (negative or positive) in key ecological attributes of an ecosystem or parts of it. We applied a systemic approach and a hierarchical framework in a comprehensive classification of stresses to biological diversity that are caused directly by global climate change. Through analyses of 20 conservation sites in 7 countries and a review of the literature, we identified climate‐change‐induced stresses. We grouped the identified stresses according to 3 levels of biological diversity: stresses that affect individuals and populations, stresses that affect biological communities, and stresses that affect ecosystem structure and function. For each stress category, we differentiated 3 hierarchical levels of stress: stress class (thematic grouping with the coarsest resolution, 8); general stresses (thematic groups of specific stresses, 21); and specific stresses (most detailed definition of stresses, 90). We also compiled an overview of effects of climate change on ecosystem services using the categories of the Millennium Ecosystem Assessment and 2 additional categories. Our classification may be used to identify key climate‐change‐related stresses to biological diversity and may assist in the development of appropriate conservation strategies. The classification is in list format, but it accounts for relations among climate‐change‐induced stresses. 相似文献

The psychological consequences of disasters are known to be significant, but research efforts in developing countries have been sporadic. This paper reports a successful collaborative project conducted in Armero, Colombia, and in Ecuador. It outlines its origins, summarizes its findings, and identifies the essential ingredients that were responsible for its positive outcome. It is recommended that these guidelines be adhered to for the development of similar projects elsewhere, to ensure a significant impact on advancing the field, policy-making, delivering appropriate mental health care, and training of providers. 相似文献

We examined whether value differences between various recreation interest/activity groups are created and sustained by the
textual information presented to their readers in magazines. Using a two-stage qualitative approach, our research sought to
explore the exact nature of the dialogue in the magazines. We sought detailed, intimate information on a selected number of
magazines to assess how the popular press socially constructs knowledge about recreation groups, and we sought to better understand
how various recreation group members assign meaning to their activities and interpret the interests of other groups. Findings
revealed limited negativity of activity users towards one another; most of the conflict found in the text of the articles
in recreational magazines was characterized as macrodispositional. Accordingly, in the articles most of the antipathy was
directed towards government because of stricter regulation of activity or towards commercial consumers whose exploitation
of resources is perceived to threaten groups' activities. Moreover, such conflict crosscuts various groups whose issues and
concerns are often similar. Since environmental battles are no longer any one group's issue, many have coalesced and engaged
in conflict with lawmakers and commercial consumers. It is clear that the recreational magazines do play a role in shaping
readers' attitudes. 相似文献
