- Low Metabolic Variation in Environmentally Diverse Natural Populations of Temperate Lime Trees (). Barker, Carl Ashton, Paul Davey, Matthew P : Population persistence for organisms to survive in a world with a rapidly changing climate will require either dispersal to suitable areas, evolutionary adaptation to altered conditions and/or sufficient phenotypic plasticity to withstand it. Given the slow growth and geographically isolated populations of many tree species, there is a high likelihood of local adaption or the acclimation of functional traits in these populations across the UK. : Given the slow growth and often isolated populations of (lime tree), we hypothesised that there is a high likelihood of local adaptation or the acclimation of metabolic traits in these populations across the UK. Our aim was to test if the functional metabolomic traits of (lime tree), collected in situ from natural populations, varied within and between populations and to compare this to neutral allele variation in the population. : We used a metabolic fingerprinting approach to obtain a snapshot of the metabolic status of leaves collected from . from six populations across the UK. Environmental metadata, longer-term functional traits (specific leaf area) and neutral allelic variation in the population were also measured to assess the plastic capacity and local adaptation of the species. : The metabolic fingerprints derived from leaf material collected and fixed in situ from individuals in six populations of . across its UK range were similar, despite contrasting environmental conditions during sampling. Neutral allele frequencies showed almost no significant group structure, indicating low differentiation between populations. The specific leaf area did vary between sites. : The low metabolic variation between UK populations of . despite contrasting environmental conditions during sampling indicates high levels of phenotypic plasticity.
