Lecture 8 - Mutualisms & Patches Flashcards
1
Q
micorrhiza
A
fungal-root mutualisms
tree gives sugfar
fungal decomposition gives N, P
2
Q
ectomycorrhiza
A
non-penetrative, 10% plant families
e.g. oak, pine
3
Q
endomycorrhiza
A
penetrative into plant roots, 85% plant families
4
Q
how honey bees pollinate
A
collect lots from lots of species, but inaccurate distribution
more pollen but less fruit set
5
Q
how wild insects collect pollinate
A
less pollen but deliver to correct species
more fruit set
6
Q
what is patch residence
A
optimal time to send feeding/travelling
marginal value theorem
maximises ratio resources intake: time spent
