Abstract

Abstract: Potential habitat characterizations for past (Late Glacial Maximum), present and future scenarios were calculated for Iberian species of D. pungens gr. ( D. pungens subsp. pungens, D. pungens subsp. langeanus, D. pungens subsp. gredensis, D. pungens subsp. brachyanthus and D. pungens subsp. hispanicus ). Results were discussed according to Allison's interpretation of insurance theory, where diversity is contrasted with resilient behaviours. Resilience is here defined as the diversification of responses to assure that functionality. The discussion of results was also compared with the morphological characterization. Environmental results confirmed the morphological similarity between these taxa. An apparent geographic divergence was observed: D. pungens subsp. hispanicus and D. pungens subsp. pungens supported an eastern response, while D. pungens subsp. langeanus and D. pungens subsp. gredensis supported a western response. The intermediate response for those extremes was supported by D. pungens subsp. brachyanthus . Based on these results, resilience in this genetic pool is concentrated on D. pungens subsp. gredensis and D. pungens subsp. hispanicus, while D. pungens subsp. langeanus, D. pungens subsp. brachyanthus and D. pungens subsp. pungens showed their resilience strategies to guarantee responses along the eastern, northern and western mountain systems for current environmental conditions only.
