Stephens, Jessica D; Santos, Scott R; Folkerts, Debbie R. (2019-05-10)
Pitcher plant bogs, or carnivorous plant wetlands, have experienced extensive habitat loss and fragmentation throughout the southeastern United States Coastal Plain, resulting in an estimated reduction to <3% of their ...

Performance of single and concatenated sets of mitochondrial genes at inferring metazoan relationships relative to full mitogenome data 

Havird, Justin C; Santos, Scott R (2019-05-10)
Mitochondrial (mt) genes are some of the most popular and widely-utilized genetic loci in phylogenetic studies of metazoan taxa. However, their linked nature has raised questions on whether using the entire mitogenome for ...
