Climate change and the management of freshwater protected areas
No full textWhile Protected Areas (PAs) have played an important role in species and ecosystem conservation, managing them with the same rulebook for coming decades without reflection or flexibility may result in adverse consequences that increase the pressures on critical biodiversity targets. Strategies for promoting more climate-resilient approaches are needed rather than focussing on maintaining past reference states. Climate change and flow regulation are leading to the development of novel ecosystems that may require new thinking and a range of novel approaches to water management to cope with increasingly uncertain futures
Conserving freshwater species in protected areas
No full textFreshwater species are those species that would disappear if inland (non-marine) habitats, disappeared or were severely degraded. These habitats include rivers, streams, lakes, ponds, swamps, marshes, bogs, fens, and aquifers. Animals dependent on these habitats account for close to 10 per cent of all animal species. Hence they are a large part of biodiversity on earth and of most Protected Areas (PAs). However, determining what is a freshwater species is difficult for some species groups because on the large variation in the degrees and types of dependence on freshwaters within the group
Freshwater ecosystems in protected areas: A synthesis
No full textIn 2014 the IUCN issued a call for a specific focus on the coverage and management of freshwater ecosystems in their own right rather than as components of Protected Areas (PAs) established for the protection of terrestrial ecosystems. The argument that freshwater PA managers need to apply freshwater-specific conservation principles and tools to ensure that PAs are effective in protecting aquatic biodiversity and ecosystem services has been extended by others
An introduction to issues for managing freshwater ecosystems in protected areas
No full textEffective management of freshwater ecosystems is critical as they have the greatest species diversity per unit area, a larger portion of threatened species, and use of their ecosystem services is generally unsustainable compared with other ecosystems
Freshwater ecological principles
No full textFive high level ecological principles common to all freshwater ecosystems are presented. Although they have different ramifications for each ecosystem type these principles are fundamental to the design and management of all freshwater Protected Areas (PAs) and the conservation of aquatic biodiversity
Water: Security, Economics and Governance
No full textWater: Security, Economics and Governance is about water scarcity, the economics of water resources, and the governance of water from an international perspective. It highlights intractable, unresolved issues, and discusses ways in which information and different conceptual approaches can be used to effectively resolve these challenges
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
