Community phylogenetics: methodological approaches and patterns in subarctic freshwater insect systems
I aimed to expand our understanding of community assembly and species co-existence by examining the implications of phylogenetic robustness on metrics describing phylogenetic community structure, as well as the phylogenetic patterns of co-occurring insect species in Churchill, MB. Using a variety of...
