To do list after talking to Rhonda

[elmacartney]

• [x] report phylogenetic signal for sub-analyses of internal and external fert (perhaps we should discuss that all insects and mammals are internal fertilisers and most external fertilisers are fish)
• [x] report more patterns in data in Fig. 1 - display fert mode on tree and which traits were measured for each species
• [x] also do an analysis on just one measure of sperm length (e.g., only take studies that report total length)
• [x] do a sub-analysis/ report patterns on the types of studies that examined sperm length (e.g., were they from a range of species)

[elmacartney]

• [x] re run models after cross-checking by Kyle

[elmacartney]

• [ ] also put p1/p2 analysis back in

[elmacartney]

• [ ] Discuss potential multi-colinearity between species and study ID in sub-analysis with @itchyshin
