Delimitation and identification of crescent butterflies (Nymphalidae: Phyciodes) in Alberta using molecular and morphological techniques
DownloadFall 2022
Species delimitation can be challenging, especially in taxonomic groups that exhibit little morphological divergence. Many techniques and concepts have been developed for detecting species boundaries, and molecular methods are becoming increasingly common. Next generation sequencing techniques...

Speciation can be an elaborate process. Delimiting species and reconstructing evolutionary relationships may be similarly complex, revealing gene tree discordance, cryptic species, geographic structuring or hybridization. In order to solve such systematic problems, a careful balance should be...

Molecular systematics of the greater fritillary butterflies (Nymphalidae: Speyeria): reduced representation sequencing, phylogeny, and incipient speciation
DownloadSpring 2020
Species delimitation and phylogenetic reconstruction are essential for understanding and categorizing lineage divergences, and ultimately species. Yet, because of the complexities underlying speciation, inferring these patterns and characterizing their sources has been a consistent challenge for...

The phylogenetic relationships of the destructive spruce budworm group of forest pests (Choristoneura fumiferana species complex) have previously been explored using allozymes, microsatellites, mitochondrial genes and a nuclear gene, but remain poorly resolved with conflicting topologies. I used...

Species delimitation in the Choristoneura fumiferana species complex (Lepidoptera: Tortricidae)
DownloadFall 2010
Species identifications have been historically difficult in the economically important spruce budworm (Choristoneura fumiferana) pest complex. Morphological, ecological, behavioural, and genetic characters have been studied to try to understand the taxonomy of this group, but diagnostic character...
