Use and misuse of the reduced major axis for line-fitting. (2009, methodology): “Because the objective usually continues to involve interpretation of the Y-axis trait, vertical deviations are taken, as they would be with OLS (e.g., Hartwig-Scherer and Martin, 1991; McHenry and Berger, 1998; Green, 2001; Weaver, 2005).”
Helpers in colonial cooperatively breeding sociable weavers Philetairus socius contribute to buffer the effects of adverse breeding conditions (2008, positive): “Fledging condition The analyses of fledging condition were conducted on body mass using body size indicators (wing and tarsus) as covariates following García-Berthou (2001) and Green (2001).”
Chemosensory assessment of rival competitive ability and scent-mark function in a lizard, Podarcis hispanica (2007, background): “Alternatively, receivers may decide to enter a scent-marked territory and try to sneak, but escape upon encountering a resident male (Gross 1996).”
Interspecific variation in avian blood parasites and haematology associated with urbanization in a desert habitat (2008, methodology): “Individuals with a greater amount of body mass for a given size are thought to have a greater amount of energy reserves and to be in better body condition (Green 2001).”
A body-condition index for ursids (2002, neutral): “Nevertheless, residuals cannot be accepted as a valid index of condition until proof is provided that certain key criteria are met (Green 2001).”
The paradigm of body condition: a critical reappraisal of current methods based on mass and length (2010, methodology): “Hence, the continuing use of ratios in fisheries and health sciences or the widespread use of Ri in terrestrial ecology, despite criticisms of these approaches (Albrecht, Gelvin & Hartman 1993; Packard & Boardman 1999; Garcı́a-Berthou 2001; Green 2001; Freckleton 2002).”
LINKING DISPERSAL TO LOCAL POPULATION DYNAMICS: A CASE STUDY USING A HEADWATER SALAMANDER SYSTEM (2003, methodology): “The functional relationship between log SVL and log mass among G. porphyriticus individuals was linear (W. H. Lowe, unpublished data), and there was no correlation between log SVL and the residuals from this regression (Pearson product-moment correlation: R , 0.0001, N 5 509, P 5 1.0) (Green 2001).”
Evaluating the validity of using unverified indices of body condition (2009, neutral): “Most authors explicitly or implicitly consider body condition to be a measure of nutrient reserves, where reserves are the quantity of utilizable tissues exceeding those required to meet daily nutritional demands (Owen and Cook 1977, Green 2001, Schulte-Hostedde et al. 2005).”
Green nesting material has a function in mate attraction in the European starling (2004, positive): “As an estimate of body condition for adults and nestlings we used body mass and not the regression residuals derived from the equation of tarsus versus mass, as this regression was not always significant (see discussion in Green 2001 ).”
Assessing the function of house sparrows' bib size using a flexible meta-analysis method (2007, background): “Body condition (mass-related condition indices) showed weak but statistical significant association with bib size (r ¼ 0.093, Table 2, Figure 1). Green (2001) emphasized the potential inappropriateness of mass-related body condition indices as they may not capture the size of a bird’s real energy ”
Sources of individual shy-bold variations in antipredator behaviour of male Iberian rock lizards (2005, background): “In addition, shyness might be a consequence of having suffered some previous stress that had increased their levels of corticosteroids (Hanley & Stamps 2002), which have immunosuppressive effects (Lochmiller 1996; Cohn 1997; Svensson et al. 2001).”
Mutual ornamentation, age and reproductive performance in the European starling (2005, methodology): “As an estimate of body condition for 18-day-old nest-lings and adults, we used body mass and not the regression residuals derived from the equation of mass versus tarsus because tarsus was not correlated with mass (Brouwer and Komdeur, 2004; see discussion in Green, 2001).”
Proximate and ultimate causes of dispersal in the Iberian lynx Lynx pardinus (2004, methodology): “Reduced major axis regression is recommended instead of ordinary least squares regression when residuals are used as an index of body condition because both x and y variables are subject to error (Green, 2001).”
Weight-Length Relationships in Fisheries Studies: The Standard Allometric Model Should Be Applied with Caution (2008, background): “However, for applications with larger juveniles and adults (eg, fish ≥1 year old), equation (1) is commonly assumed to hold over the entire size range and a single regression is fit to log-transformed weight–length measurements ( Ricker 1975 ; Green 2001 ).”
