Hostplant change and paleoclimatic events explain diversification shifts in skipper butterflies (Family: Hesperiidae)

BMC Evol Biol
PMCID: 5541431
PMID: 28768477
DOI: 10.1186/s12862-017-1016-x

[…] ylidae, which is the sister family to Hesperiidae [], were acquired from Genbank and treated as outgroups. We estimated the most appropriate partitioning scheme for the data matrix using TIGER v1.02 (Tree Independent Generation of Evolutionary Rates) [] and the nucleotide substitution models for the partitions by PartitionFinder v1.1.1 []. We assumed a relaxed clock model that allowed branch lengt […]


Multiple measures could alleviate long branch attraction in phylogenomic reconstruction of Cupressoideae (Cupressaceae)

Sci Rep
PMCID: 5264392
PMID: 28120880
DOI: 10.1038/srep41005

[…] PCG-Iss-73”, “PCG-slope-70” and “PCG-R2-71” matrices were built by removing saturated genes detected in these two analyses.Fifth, we built rate-partitioned data subsets. Observed variability (OV) and Tree Independent Generation of Evolutionary Rates (TIGER) methods were used to measure the relative evolutionary rate for each of the aligned nucleotide sites in PCG. Using methods previously describe […]


Ten genes and two topologies: an exploration of higher relationships in skipper butterflies (Hesperiidae)

PMCID: 5144725
PMID: 27957386
DOI: 10.7717/peerj.2653
call_split See protocol

[…] lyses, we used the GTR model of substitution with gamma model of rate heterogeneity (GTR+G) and different partition schemes, either gene-based or based on rates of evolution calculated by the program Tree Independent Generation of Evolutionary Rates (TIGER) (). In gene-based partitions each gene was considered as a separate partition, while in TIGER-based partitions, the characters were binned tog […]
