Intraspecific life history variation in contrasting habitats: Insights from an obligate symbiotic organism

Abstract: Our results demonstrate that contrasting habitats selected for differences in the demography and life history traits of a lichen species. Consistent with life history theory predictions, in the habitat with slower growth, started to reproduce at a smaller size and its reproductive allocation was higher. This study extends the scope of life history theory and improves our understanding of life history patterns and variations in overlooked taxa such as lichens.

“…(e.g., [69]). Furthermore, standardisation of growth rates and thallus size requires that multiple covariables, such as the effects of reproductive stage, substratum type and variation in microclimate also be taken into account [70,71]. Having achieved this sufficient level of control, observation of small-scale temperature effects on the freshwater lichen Dermatocarpon rivulorum, in a closely monitored stretch of subalpine watershed, has led Shivarov et al [72] to propose variability of thallus size and colony extension as a trait for monitoring the effects of climate change.…”
