Facilitation = Positive
Interactions
Many plants rely on insects for pollination and co-evolution is common
Facilitation between plants and pollinators = shared access to resources
Purpose
To determine the importance of neighbouring
flowering plants on the pollination of Myosotis
alpestris
Hypothesis
Flowering neighbour presence will
have an net positive effect on the
pollination of Myosotis alpestris
Predictions
1. Visitation rate of pollinators will
be higher when neighbours are
present
2. Pollinator richness will be higher
when neighbours are present

Conclusion
Neighbour presence and identity influences
visitation rate and distribution associated
with flowering plants
Preliminary evidence indicates not all
insects are necessarily subject to magnet
effect
Implications
Facilitation is important in alpine where
there harsh conditions and scarce
pollinators
Pollination reproduction
