“…These general concepts have also received more attention than other concepts within the evolutionary applications literature (Cook & Sgrò, 2017). Interestingly, evolution as a concept was not reported to be as important as adaptation and genetic diversity, potentially supporting concerns that rapid evolution is not being perceived as relevant to management (Ashley et al., 2003; Kinnison et al., 2007; Smith et al., 2014). This pattern also seems to suggest a poor understanding of the links between genetic diversity, adaptive capacity and evolution, which has also been observed in conservation policy (Cook & Sgrò, 2017).…”

“…However, without asking respondents to define each of the concepts, it is not possible to truly judge their specific level of understanding, or the consistency of interpretations among respondents. Poor understanding of evolutionary biology has been repeatedly suggested as a barrier to evolutionarily enlightened management (Ashley et al., 2003; Frankham, 2010; Mace & Purvis, 2008). Our results suggest that increased training in evolutionary biology may increase the value managers place on these concepts, and possibly their potential to integrate them into management.…”

“…Some of these barriers are within the control of scientists and managers to address, such as a lack of understanding of the relevant concepts (Ashley et al., 2003; Frankham, 2010) and poor engagement between scientists and managers (Hoban et al., 2013; Mace & Purvis, 2008). However, some barriers are beyond the control of both groups, such as insufficient resources to make changes to existing management practices (Figure 4a).…”

“…Specifically, changes to management practice require the development of tools that enable managers to identify the practical changes needed for evolutionarily enlightened management. However, criticisms have been made that evolutionary theory continues to be ignored within existing decision tools, such as population viability analysis (Ashley et al., 2003; Frankham, 2010) and species distribution models (Urban et al., 2016). In other cases, there is a failure to translate theory into practical management recommendations that managers could implement (Cook & Sgrò, 2017).…”

Despite wide acceptance that conservation could benefit from greater attention to principles and processes from evolutionary biology, little attention has been given to quantifying the degree to which relevant evolutionary concepts are being integrated into management practices. There has also been increasing discussion of the potential reasons for a lack of evolutionarily enlightened management, but no attempts to understand the challenges from the perspective of those making management decisions. In this study, we asked conservation managers and scientists for their views on the importance of a range of key evolutionary concepts, the degree to which these concepts are being integrated into management, and what would need to change to support better integration into management practices. We found that while managers recognize the importance of a wide range of evolutionary concepts for conservation outcomes, they acknowledge these concepts are rarely incorporated into management. Managers and scientists were in strong agreement about the range of barriers that need to be overcome, with a lack of knowledge reported as the most important barrier to better integration of evolutionary biology into conservation decision‐making. Although managers tended to be more focused on the need for more training in evolutionary biology, scientists reported greater engagement between managers and evolutionary biologists as most important to achieve the necessary change. Nevertheless, the challenges appear to be multifaceted, and several are outside the control of managers, suggesting solutions will need to be multidimensional.

“…Recognition of the extent and pace of contemporary evolution is critical to conservation efforts [82]. The present survey includes representatives from four steelhead Distinct Population Segments in California [83], as well as three divergent O. mykiss lineages and three of the hatchery rainbow trout strains most commonly stocked in California.…”

Rapid parallel evolution of standing variation in a single, complex, genomic region is associated with life history in steelhead/rainbow trout

et al. 2014

Rapid adaptation to novel environments may drive changes in genomic regions through natural selection. Such changes may be population-specific or, alternatively, may involve parallel evolution of the same genomic region in multiple populations, if that region contains genes or co-adapted gene complexes affecting the selected trait(s). Both quantitative and population genetic approaches have identified associations between specific genomic regions and the anadromous (steelhead) and resident (rainbow trout) lifehistory strategies of Oncorhynchus mykiss. Here, we use genotype data from 95 single nucleotide polymorphisms and show that the distribution of variation in a large region of one chromosome, Omy5, is strongly associated with life-history differentiation in multiple above-barrier populations of rainbow trout and their anadromous steelhead ancestors. The associated loci are in strong linkage disequilibrium, suggesting the presence of a chromosomal inversion or other rearrangement limiting recombination. These results provide the first evidence of a common genomic basis for life-history variation in O. mykiss in a geographically diverse set of populations and extend our knowledge of the heritable basis of rapid adaptation of complex traits in novel habitats.
