Ecological networks, nestedness and sampling effort (2007, methodology): “The nestedness calculator has been criticized for overestimating the nestedness significance, as it uses a null model based on equal probability for all interactions to be realized (Cook & Quinn 1998; Fischer & Lindenmayer 2002).”
BIODIVERSITY RESEARCH: Nestedness for different reasons: the distributions of birds, lizards and small mammals on islands of an inundated lake (2010, methodology): “However, the NTC has problems relating to the definition of the isocline of perfect order, the way of matrix reorganization, the robustness of the packing algorithm and choice of an appropriate null model (Fischer & Lindenmayer, 2002; Rodrı́guez-Gironés & Santamarı́a, 2006).”
The virtual ecologist approach: simulating data and observers (2010, background): “Patterns tested have considered nestedness (Fischer and Lindenmayer 2002, Greve and Chown 2006, Higgins et al. 2006, Ulrich and Gotelli 2007a, 2007b) and trait, phylogenetic and species diversity (Kraft et al. 2007).”
Edge effects on flower-visiting insects in grapefruit plantations bordering premontane subtropical forest. (2005, background): “It has been argued, however, that Nestedness Calculator may overestimate the degree of nestedness and its statistical significance, because the null model assumes that all species are equally common ( Fischer & Lindenmayer 2002 ).”
A consumer's guide to nestedness analysis (2009, background): “…models in nestedness analysis, and the inference of mechanism from a pattern of nestedness (Cook and Quinn 1998, Wright et al. 1998, Jonsson 2001, Fischer and Lindenmayer 2002, 2005, Maron et al. 2004, Greve and Chown 2006, Higgins et al. 2006, Rodrı́guez-Gironés and Santamarı́a 2006, Burgos et…”
Network properties of an epiphyte metacommunity (2007, background): “…provide the best solution; (ii) the isocline reflecting a perfectly ordered matrix is not uniquely defined; and (iii) the null model used to establish deviations from randomized expectations underestimates type-1 error rates (see also Cook & Quinn 1998; Fischer & Lindenmayer 2002; Bascompte et al .”
Amphibians in a human-dominated landscape: the community structure is related to habitat features and isolation (2004, methodology): “The null-model used by Atmar and Patterson Nested Calculator (1993; 1995) to evaluate the nestedness were recently criticised, since it can lead to overestimate the nestedness level ( Fisher and Lindenmayer, 2002 ).”
On nestedness analyses: rethinking matrix temperature and anti‐nestedness (2007, background): “The T metric has become established as the standard measure of the degree of nestedness in studies of species distribution among sites (Fischer and Lindenmayer 2002) and of ecological interaction networks (Bascompte et al.”
The Structure of Plant-Animal Mutualistic Networks (2006, background): “…discussions have revolved around how ecological 1the alternative, transposed arrangement with animals as rows and plants as columns is also frequently used conclusions depend on the choice of a null model (Cook and Quinn 1998, Gotelli 2001, Fischer and Lindenmayer 2002, Vázquez and Aizen 2003).”
Species abundance distributions: moving beyond single prediction theories to integration within an ecological framework. (2007, background): “…occurring on larger patches can also be created entirely by a passive sampling process from a hollow curve SAD – the species found on all patches are the abundant species while the species found only on the large patches are the rare species (Connor & McCoy 1979; Fischer & Lindenmayer 2002).”
The relationship between wetland hydroperiod and nestedness patterns in assemblages of larval amphibians and predatory macroinvertebrates (2004, background): “Thus, the statistical significance of a nested distributional pattern should always be interpreted with caution (Fischer and Lindenmayer 2002).”
Dragonfly community re‐organisation in boreal forest lakes: rapid species turnover driven by climate change? (2008, background): “…analysis is currently under debate, as it has been shown that even randomly generated data sets may in some cases indicate significant nesting (Fischer & Lindenmayer, 2002, but cf. Simberloff & Martin, 1991; Wright & Reeves, 1992; Atmar & Patterson, 1993; Wright et al., 1998; Suhling et al.,…”
Effects of large-scale disturbance on metacommunity structure of terrestrial gastropods: temporal trends in nestedness (2007, background): “…differences in composition among patches or islands (i.e. passive sampling; Coleman 1981, Coleman et al. 1982), then nestedness may appear more prevalent simply because differences in abundances of species are large (Andrén 1994, Cutler 1994, Fischer and Lindenmayer 2002, Higgins et al. 2006).”
Disentangling community patterns of nestedness and species co‐occurrence (2007, background): “Our results also corroborate recent critiques of the equiprobable model by Fischer and Lindenmayer (2002), Rodrı́guez-Gironés and Santamarı́a (2006) and Ulrich and Gotelli (2007), who all found that this model is prone to sampling artefacts.”
Community structure and differential responses of aquatic turtles to agriculturally induced habitat fragmentation (2006, background): “1998), but this may overestimate significance as an artifact of passive sampling (Fischer and Lindenmayer 2002).”
Biodiversity, species interactions and ecological networks in a fragmented world (2012, background): “This skewed structure affects several network metrics including nestedness, connectance and asymmetry (e.g. Blüthgen et al., 2008), although sampling artefacts need to be ruled out (Fischer and Lindenmayer, 2002; Lewinsohn et al., 2006; Vázquez, 2005; Vázquez et al., 2007; Woodward et al., 2010b).”
Rapid avifaunal collapse along the Amazonian deforestation frontier (2006, background): “The program does have some shortcomings ( Fischer and Lindenmayer, 2002 ) and some absences within the matrix may be an artefact of undersampling (Cam et al., 2000) but this was only likely to be the case in the largest forest sites.”
Contrasting patterns and mechanisms of spatial turnover for native and exotic freshwater fish in Europe (2009, background): “In this null model, the probability of occupancy of each species is proportional to its observed frequency of occurrence and the total number of species per basin is equiprobable (Fischer & Lindenmayer, 2002).”
