Recent and future climatic changes

Western mediterranean basin for the next

century:

3-4ºC increase in mean annual temperature

Up to 50% less rainfall in summer

In the present

Increased frecuency of large-scale fires

Differences in adaptive traits

Drought resistance (Voltas et al. 2007, Grivet et al. 2009)

Reproductive allocation (Climent et al. 2008)

Reproductive allocation and costs of reproduction Principle of Allocation

If resources are limited, two or more processes compete for them

Negative correlation between investment in one process (allocation) respect to other/s costs

Allocation strategies are evolutionary meaningful (adaptive) and are linked with life history traits

Questions to answer

Is there intraspecific variability in Pinus halepensis in terms of reproductive allocation? (yes, Climent et al. 2008)

How can we explain those differences/ lack of differences (ecology/evolution)?

How can we use this information to increase forest resilience?

Looking for (genetically inherited) variation

Reproduction along development

I. Early stages: threshold size for reproduction

II. Secondary stages: reproductive allocation

Conclusions There exist evolutionary constraints between

reproduction and growth For Aleppo pine, reproduction is more

adaptive than total growth Natural selection finely shapes reproductive

strategies

Local conditions Climatic clines Recent historical colonization
