Differences between pollination and fruit/seed dispersal?
Male figs are or are not meant to be eaten by a seed disperser?
Should not
Female figs are or are not meant to be eaten by a seed disperser?
Should
Multivariate oder space?
the ones up there on the y axis with dark dots should not be eaten since they are male figs. They produce an oder that repels birds, and does not produce an oder that bats are attracted to. Light dots down there to the right should be eaten. They produce an oder that bats are attracted to.
Birds are mostly making choices to eat a fig by ______ if they are not repelled by a bird repellent?
Colour
Relationship between seed size, retention in animal’s gut, and distance dispersed from parent?
Low time retained, insufficient enzyme exposure, low seed germination
Middle time retained, safe passage time, high seed germination
High time retained, seed destroyed by gut enzymes, low seed germination
Fake fruit without pulp extract were retained in G1 tract longer or shorter between real fruits or fake with pulp?
Longer
Germination diminished with _________ in gut?
retention
Is there a limit to how far seeds should go?
Yes, longer or really short is not good.
Elaiosome?
Ants aren’t interested so much in the seeds but in the elaiosome.
Are elaiosomes more nutritious than seeds?
More, especially in free fatty acid and amino acid content
What is one big reason to use multivariate oder space for elaiosomes?
Complex chemical datasets and plot them in two dimensions?
