Evolution of Ecological Niche Breadth (2017, background): “…genetic parameters such as genetic correlations cause meaningful constraints (Conner 2012), and others argue that selection may actually deplete genetic variance faster than the rate at which favorable mutation can generate it for complex, multitrait adaptations (Blows & Hoffmann 2005).”
Ecological and evolutionary responses of Mediterranean plants to global change. (2014, unknown): “Significant differences among families (or clones) in the target trait signify its potential for evolution (Blows and Hoffmann, 2005; Hoffmann and Sgrò, 2011).”
Adaptation and Fitness in Animal Populations: Evolutionary and Breeding Perspectives on Genetic Resource Management (2009, background): “…but recent papers (primarily reviews) that provide an introduction to these developments include papers in the special issue of Genetica (Hendry and Kinnison 2001 – particularly Agrawal et al. 2001, Arnold et al. 2001 and Wade 2001), Blows (2007), Blows and Hoffmann (2005) and Carter et al. (2005).”
Unifying and Testing Models of Sexual Selection (2006, background): “Although we do not discuss the lek paradox extensively, new multivariate methods indicate it is far from resolved (see Blows & Hoffmann 2005).”
Bringing the Hutchinsonian niche into the 21st century: Ecological and evolutionary perspectives (2009, background): “Evolutionary biologists often assume that characters always have genetic variation upon which natural selection can act, but there is growing evidence that in some species, genetic variation may be absent for key traits determining niches and range limits, particularly in sparse populations prone to”
Why Reproductive Systems Matter for the Invasion Biology of Plants (2010, background): “Genetic constraints can restrict opportunities for the evolution of local adaptation, but there is little empirical evidence on how commonly they infl uence response to selection in natural populations (Antonovics 1976 ; Blows & Hoffman 2005 ).”
Ecogeographical rules: elements of a synthesis (2008, background): “Moreover, gene flow or limited genetic variance might limit the potential for variation in local adaptation across the ranges of narrowly distributed species (Blows & Hoffmann, 2005; Chown & Terblanche, 2007).”
Genetic variation across species’ geographical ranges: the central–marginal hypothesis and beyond (2008, background): “The resulting stochastic reduction of genetic diversity within populations at geographical range margins may limit their evolutionary potential, thereby inhibiting adaptation to conditions beyond the range limit (Hoffman & Blows 1994; Hoffmann & Parsons 1997; Gaston 2003; Blows & Hoffmann 2005).”
Conservation implications of species–genetic diversity correlations (2014, result): “…seem to emphasize connectivity since four of the seven studies reporting statistically significant β-SGDCs considered connectivity to be related to parallel patterns of community and population differentiation (Sei et al., 2009; Odat et al., 2010; Papadopoulou et al., 2011; Blum et al., 2012).”
Quantitative genetics of growth and cryptic evolution of body size in an island population (2007, methodology): “…that genetic constraints will not always be apparent from consideration of h2 and rG alone (Pease and Bull 1988), and that multivariate statistical methods (e.g., eigenvector analysis of genetic variance–covariance matrices) should additionally be used for their detection (Blows and Hoffman 2005).”
Limits to evolution at range margins: when and why does adaptation fail? (2007, background): “Nonetheless, a species will have a range edge if it fails to adapt in only one important trait [ 39 ], and some traits might have limited genetic variation, even if overall genetic variance is high.”
Heritability is not Evolvability (2011, background): “The opposite view is that various forms of variational constraints can influence trait dynamics over longer macroevolutionary time scales (e.g. Hansen and Houle 2004; Blows and Hoffmann 2005; Kirkpatrick 2009; Walsh and Blows 2009).”
The evolution of trade‐offs: where are we? (2007, background): “Even if there are no eigenvalues that are exactly zero, movement along a particular evolutionary trajectory may be very slow if the eigenvalue in that direction is very small relative to the other eigenvalues (Blows & Hoffmann, 2005).”
