Overview
Syllabus
Intro
Ecological opportunity and adaptive radiation
What is an 'adaptive radiation ?
Anolis lizards also underwent adaptive radiation.
What is an "adaptive radiation"? • Diverse and closely related species that vary in useful trait
Frog diversity in the Philippines and Sulawesi
Fanged frogs have high morphological diversity on Sulawesi
Questions about fanged frogs
Initial fieldwork and sampling
Different ecotypes are sympatric in different parts of Sulawesi
Alternative hypothesis: Adaptive radiation
Phylogenetic expectations
Evolution of body size
Medium-sized species are found in slow moving water
Do these frogs differ in ecology?
And some fanged frogs guard eggs!
And and at least one species has internal incubation of tadpoles!
Did fanged frogs undergo an adaptive radiation?
Why did different ecotypes evolve on different
Toad samples and data
MtDNA variation in Sulawesi toads
Protected Areas on Sulawesi
Ratan extraction
