• Comparison of methods to detect rare and cryptic species: A case study using the red fox (Vulpes vulpes) (2009, neutral): “be compromised further by poor weather, visual obstruction by dense habitat, interference from non-target species and deployment of inexperienced field personnel (Wilson and Delahay 2001).”
• Controlling introduced predators in the Gibson Desert of Western Australia (2003, background): “snow-track count index and actual numbers of lynx but this involved a small number of surveys (Wilson and Delahay, 2001).”
• Spatial ecology of the European wildcat in a Mediterranean ecosystem: dealing with small radio‐tracking datasets in species conservation (2009, methodology): “Among the methodological alternatives available, radiotracking and camera trapping are broadly used (Kenward, 2001; Wilson & Delahay, 2001).”
• An evaluation of field and noninvasive genetic methods for estimating Eurasian otter population size (2009, methodology): “…other field methods, such as mud-tracking and counting of individuals using direct observation or remote cameras (e.g. Smallwood and Fitzhugh 1993; Cutler and Swann 1999; Ruiz-Olmo et al. 2001; Wilson and Delahay 2001), their use is generally even more confined to special conditions or locations.”
• Drought-driven change in wildlife distribution and numbers: a case study of koalas in south west Queensland (2011, background): “Identifying species presence can be done through direct observation, but in many cases indirect signs such as scats or tracks are used (Wilson and Delahay 2001; Telfer et al. 2006).”
• Estimating population density from indirect sign: track counts and the Formozov–Malyshev–Pereleshin formula (2006, background): “Both deer (Schwarz & Seber, 1999) and many Carnivora (Wilson & Delahay, 2001) are notoriously hard to survey using direct counts.”
• Estimating population size and trends of the Swedish brown bear Ursus arctos population (2011, methodology): “…parameters are used to assess population status, decide quotas for harvested populations, evaluate the effects of management measures or decisions (Wilson & Delahay 2001), or to obtain parameters for conservation principles 114 WILDLIFE BIOLOGY 17:2 (2011) including the IUCN criteria for…”
• Estimation of badger abundance using faecal DNA typing (2003, methodology): “Methods based on quantifying field signs have also been employed, but these can be strongly influenced by sources of error associated with environmental factors (reviewed in Wilson & Delahay 2001).”
• Estimating Brown Hyaena Occupancy Using Baited Camera Traps (2009, methodology): “…1978; Smithers 1978; Grobler 1981; Rowe-Rowe 1982; Nowell & Jackson 1996) or have performed well as baits or lures in other carnivore studies (Zielinski 1995; Andelt & Wooley 1996; Bradshaw et al. 2000; McDaniel et al. 2000; Wilson & Delahay 2001; Moruzzi et al. 2002; Mickleburgh & Fisher 2003).”
• Surveying carnivores at large spatial scales: a comparison of four broad-applied methods (2007, background): “…1975; Smallwood and Fitzhugh 1995; Zielinski and Kucera 1995; Zielinski and Stauffer 1996), but also in the United Kingdom (Tuyttens et al. 2001; Wilson and Delahay 2001; Sadlier et al. 2004; Webbon et al. 2004), have emphasised the use of alternative sampling methods to obtain density…”
• A Comparison of Noninvasive Techniques to Survey Carnivore Communities in Northeastern North America (2006, background): “…Bulletin 34(4) While there have been several reviews of carnivore survey techniques (e.g., Raphael 1994, Zielinski and Kucera 1995, Gese 2001, 2004, Wilson and Delahay 2001), and some techniques have been compared and critiqued on a case-bycase basis (e.g., Foresman and Pearson 1998, Harrison et…”
• Influence of landscape characteristics on carnivore diversity and abundance in Mediterranean farmland (2009, background): “…(e.g., Walker et al., 2000), this approach is generally considered valid for studies conducted at the landscape or regional scales (Virgós, 2001; Wilson and Delahay, 2001; Beja et al., in press), based on strong evidence indicating a good fit between carnivore field signs and population…”
