Improving density estimates for elusive carnivores: Accounting for sex-specific detection and movements using spatial capture–recapture models for jaguars in central Brazil (2011, background): “Controversially, similar studies for leopards (Balme et al., 2009) and ocelots (Maffei and Noss, 2008) reached the opposite conclusion.”
Evaluating capture–recapture population and density estimation of tigers in a population with known parameters (2010, background): “Few studies have actually evaluated the appropriateness of mark–recapture models in field situations for obtaining unbiased estimates of population size and density of carnivores (Wegge, Pokheral & Jnawali, 2004; Soisalo & Cavalcanti, 2006; Dillon & Kelly, 2007; Maffei & Noss, 2008).”
Design, evaluate, refine: camera trap studies for elusive species (2008, background): “The number of camera stations deployed for a target species can range, for example, from 17 (Kelly, 2003) to 32 (Wallace et al., 2003), and the extent of area surveyed can differ by orders of magnitude (DiBitetti, Paviolo & De Angelo, 2006; Maffei & Noss, 2007).”
Evaluating the potential biases in carnivore capture–recapture studies associated with the use of lure and varying density estimation techniques using photographic-sampling data of the Malagasy civet (2011, background): “Despite this frequent need to estimate the ETA, there is still much debate on a robust solution; most recommendations suggest variations on ad hoc boundary-strip methods (Soisalo and Cavalcanti 2006; Dillon and Kelly 2007; Maffei and Noss 2008; Balme et al. 2009).”
Density and activity patterns of ocelots (Leopardus pardalis) in northern Peru and the impact of oil exploration activities (2010, methodology): “…and camera surveys, indicate that this methodology will typically overestimate density values (Dillon and Kelly, 2008; Soisalo and Cavalcanti, 2006), Maffei and Noss (2008) found that ½MMDM from a camera-trapping survey was a reliable estimate of the actual home range radius of tracked ocelots.”
Jaguar Panthera onca population decline in the Upper Paraná Atlantic Forest of Argentina and Brazil (2008, methodology): “However, in some situations using ½ MMDM as the buffer could inflate density estimates (Trolle & Kéry, 2003; Soisalo & Cavalcanti, 2006; Maffei & Noss, 2007) and, if radiotelemetry data exist, the best buffer should be the radius of the estimate of mean home range (Soisalo & Cavalcanti, 2006).”
Ocelot home range, overlap and density: comparing radio telemetry with camera trapping (2008, background): “A nested grid approach (Maffei & Noss, 2008) may aid in determining the appropriate camera spacing for a target species.”
Camera-trap studies of maned wolf density in the Cerrado and the Pantanal of Brazil (2007, background): “Noss and Maffei (2005) recommend that the area covered by camera traps be at least 4 times the size of the average home range of the species in question.”
Estimating Puma Densities from Camera Trapping across Three Study Sites: Bolivia, Argentina, and Belize (2008, methodology): “As a guideline, Maffei and Noss (2008) suggest a survey area of 3–4 times the average home-range size of the target species.”
Comparison of density estimation methods for mammal populations with camera traps in the Kaa‐Iya del Gran Chaco landscape (2012, methodology): “…al., 2009), ocelot Leopardus pardalis (Trolle & Kéry, 2003; Maffei et al., 2005; di Bitetti, Paviolo & de Angelo, 2006; Dillon & Kelly, 2007, 2008; Maffei & Noss, 2008), Pampas cat Leopardus colocolo (Gardner et al., 2010), Andean cat Leopardus jacobita (Reppucci, Gardner & Lucherini, 2011),…”
