Assessing species' vulnerability to climate change is a prerequisite for developing effective strategies to conserve them. The last three decades have seen exponential growth in the number of studies evaluating how, how much, why, when, and where species will be impacted by climate change. We provide an overview of the rapidly developing field of climate change vulnerability assessment (CCVA) and describe key concepts, terms, steps and considerations. We stress the importance of identifying the full range of pressures, impacts and their associated mechanisms that species face and using this as a basis for selecting the appropriate assessment approaches for quantifying vulnerability. We outline four CCVA assessment approaches, namely trait?based, correlative, mechanistic and combined approaches and discuss their use. Since any assessment can deliver unreliable or even misleading results when incorrect data and parameters are applied, we discuss finding, selecting, and applying input data and provide examples of open?access resources. Because rare, small?range, and declining?range species are often of particular conservation concern while also posing significant challenges for CCVA, we describe alternative ways to assess them. We also describe how CCVAs can be used to inform IUCN Red List assessments of extinction risk. Finally, we suggest future directions in this field and propose areas where research efforts may be particularly valuable.
Global Atlas of Marine Fisheries: A critical appraisal of catches and ecosystem impacts

Until now, there has been only one source of data on global fishery catches: information reported to the Food and Agriculture Organization of the United Nations by member countries. An extensive, ten-year study conducted by The Sea Around Us Project of the University of British Columbia shows that this catch data is fundamentally misleading. Many countries underreport the amount of fish caught (some by as much as 500%), while others such as China significantly overreport their catches. The Global Atlas of Marine Fisheries is the first and only book to provide accurate, country-by-country fishery data. This groundbreaking information has been gathered from independent sources by the world’s foremost fisheries experts, and edited by Daniel Pauly and Dirk Zeller of the Sea Around Us Project. The Atlas includes one-page reports on 273 countries and their territories, plus fourteen topical global chapters. National reports describe the state of the country's fishery, by sector; the policies, politics, and social factors affecting it; and potential solutions. The global chapters address cross-cutting issues, from the economics of fisheries to the impacts of mariculture. Extensive maps and graphics offer attractive and accessible visual representations. While it has long been clear that the world’s oceans are in trouble, the lack of reliable data on fishery catches has obscured the scale, and nuances, of the crisis. The atlas shows that, globally, catches have declined rapidly since the 1980s, signaling an even more critical situation than previously understood. The Global Atlas of Marine Fisheries provides a comprehensive picture of our current predicament and steps that can be taken to ease it. For researchers, students, fishery managers, professionals in the fishing industry, and all others concerned with the status of the world’s fisheries, the Atlas will be an indispensable resource.

The freshwater ichthyofauna of the Fiji islands remained poorly documented before the establishment of the Pacific-Asia Biodiversity Transect (PABITRA) network. The PABITRA approach assesses biodiversity along ocean-to-mountain transects and promotes sustainable land use on islands across the Pacific. Multiple surveys of freshwater fish species along the Viti Levu PABITRA transect have contributed six new occurrence records and one new species to the known freshwater fishes of Fiji since 2002. In total, 21 indigenous species of fish (9% endemic) from 10 families and no introduced fishes were found in the three PABITRA sites. Diversity was highest (16 species) at Savura forest reserve and decreased further inland into Sovi and Wabu. The assemblage found is dominated by highly migratory species (95%) that traverse the different aquatic habitats (marine, estuarine, lowland and upland streams) covered by the PABITRA transect. This high degree of connectivity highlights several growing issues affecting aquatic fauna on the high island of Viti Levu. The reduction in forest cover along the gateway transects, especially in the terminal reaches, and infrastructure development such as dams and weirs have deleterious effects on the migration routes of the Fijian ichthyofauna. Several species collected are important food sources and have cultural totemic importance to local inhabitants along the vertical transect. This paper documents the ichthyofauna of the Fiji gateway transect, ecological characteristics of this assemblage, IUCN Redlist conservation assessment status and highlights factors affecting the fragility and resilience of these communities, particularly focusing on the importance of life-history patterns and watershed conditions.
