Recent analyses (Clout, 2001; Cullen et al. 2005; Hartley, 1997; Joseph et al. 2008; Joseph et al. 2009) of the management of New Zealand?s biodiversity have highlighted the challenge of allocating limited resources, especially the funding of threatened species. Our essay includes frequent citation of Joseph et al. (2008, 2009) as the Project Prioritization Protocol (PPP) modal proposed in their papers is co-written by Department of Conservation (DOC) staff, and may be the metric used in future allocation of resources to New Zealand?s threatened species. Limited resourcing of threatened species management and recovery is a worldwide problem, extensively documented in the conservation literature (Spring et al. 2007; Sutherland, 2009). Reviews of conservation management practices (Craig and Stewart, 1994; Sutherland, 2009; Sutherland et al. 2004; Ussher, 1999) have called for the justification of conservation research by quantifying biodiversity changes and testing solutions. Therefore it is appropriate that novel strategies such as those presented by Joseph et al. (2008, 2009) are available for assessment. Any suggestions for improvement must engage a full debate on the current demands on natural resources (Sarukhan and Whyte, 2005) and the emerging threats to biodiversity, such as climate change (Kostyack and Rohlf, 2008). Development and Implementation of management strategies for threatened species need to be cognizant of not only the ecological (Clark et al. 1994; Tear et al. 1993) needs of threatened species, but also cultural (Charnley, 2006; Craig and Stewart, 1994; McBride et al. 2007) and economic (Craig, 1998; Cullen et al. 2005; Moran, 2003; Perhans et al. 2008; Sinden, 2004) factors.

SummaryThe issues that need to be addressed in conservation education programmes aimed at saving threatened species in Africa are discussed. Elements considered as crucial for the success of such programmes include a clear definition of the problem, identification of the target groups, definition of appropriate messages for each group, and development of suitable strategies for dissemination. The advantages of using local people to implement education programmes are outlined. A system for monitoring and evaluation is essential for the assessment of the success of programmes and provides opportunities for improvement, re-definition of priorities and reallocation of resources.

Environmental DNA metabarcoding has recently emerged as a non-invasive tool for aquatic biodiversity inventories, frequently surpassing traditional methods for detecting a wide range of taxa in most habitats. One of the major limitations currently impairing the large-scale application of DNA-based inventories, such as eDNA or bulk-sample analysis is the lack of species sequences available in public genetic databases. These gaps are still largely unknown spatially and taxonomically for most regions of the world, which can hinder targeted future sequencing efforts. We propose GAPeDNA, a user-friendly web-interface (Fig. 1) that provides a global overview of genetic database completeness for a given taxon across space and conservation status. As an initial application, we synthetized data from regional checklists for marine and freshwater fishes along with their IUCN conservation status to provide global maps of species coverage using the European Nucleotide Archive public reference database for 19 metabarcoding primers. This tool automatizes the scanning of gaps in these databases to guide future sequencing efforts and support the deployment of DNA-based inventories at larger scale. It is flexible and can be expanded to other taxa and primers upon data availability. Using our global fish case study, we show that gaps increase toward the tropics where species diversity and the number of threatened species were the highest. It highlights priority areas for fish sequencing like the Congo, the Mekong and the Mississippi freshwater basins which host more than 60 non-sequenced threatened fish species. For marine fishes, the Caribbean and East Africa host up to 42 non-sequenced threatened species. As an open-acces, updatable and flexible tool, GAPeDNA can be used to evaluate the completeness of sequence reference libraries of various markers and for any taxonomic group.
