Major Points: - Population vs Community - Symbioses are a spectrum from Parisitism to Mutualism - Competition leads to resource partitioning because competition is bad for everyone involved - "Niche" is how an organism makes a living. Realized niche is fundamental niche minus competition - Trophic structure is limited by thermodynamics - Why are big fierce animals rare? - How to define and measure biodiversity? (richness and evenness) - How to compare similarity of two communities with a bunch of different species? (How to read an ordination plot) - Community ecology in "real life" - Microbiomes - Forensics - Attine ants as a model system to study ecological interactions (Behaviors, Pathogens, Competition, Population growth, coevolution, symbioses, microbiomes, etc.)
