1

• Reduce take- off of ballooning spiders

• Reduce distance of wind dispersal seeds

Increased emigration rates, even when local populations are at low densities

Promote risky movement behaviours, enhancing the possibility of long distance dispersal even if mortality is

Foster investment in dispersal traits at the expense of other life-history attributes

IV Conclusion

Climate change has many effects on the evolution of dispersal in many aspect and individuals also have

responses to this change

However, interventions seem essential to avoid species extinctions under climate change
