Data from: The loss of hemoglobin and myoglobin does not minimize oxidative stress in Antarctic icefishes

Kristin M. O'Brien, Elizabeth L. Crockett, Jacques Philip, Corey A. Oldham, Megan Hoffman, Donald E. Kuhn, Ronald Barry & Jessica McLaughlin
The unusual pattern of expression of hemoglobin (Hb) and myoglobin (Mb) among Antarctic notothenioid fishes provides an exceptional model system for assessing the impact of these proteins on oxidative stress. We tested the hypothesis that the lack of oxygen-binding proteins may reduce oxidative stress. Levels and activity of pro-oxidants, small-molecule and enzymatic antioxidants, and levels of oxidized lipids and proteins in liver, oxidative skeletal muscle, and heart ventricle were quantified in five species of notothenioid...

Data from: Apex predators and the facilitation of resource partitioning among mesopredators

Kelly J. Sivy, Casey B. Pozzanghera, Kassidy E. Colson, Matthew A. Mumma & Laura R. Prugh
Apex predators may influence carnivore communities through the suppression of competitively dominant mesopredators, however they also provide carrion subsidies that could influence foraging and competition among sympatric mesopredators when small prey is scarce. We assessed coyote Canis latrans and red fox Vulpes vulpes winter diet overlap and composition from scats collected in two study areas with >3-fold difference in grey wolf Canis lupus density due to a wolf control program. We hypothesized that differences in...

Data from: Integrating phylogenomic and population genomic patterns in avian lice provides a more complete picture of parasite evolution

Parasite diversity accounts for most of the biodiversity on earth, and is shaped by many processes (e.g. cospeciation, host-switching). To identify the effects of the processes that shape parasite diversity, it is ideal to incorporate both deep (phylogenetic) and shallow (population) perspectives. To this end, we developed a novel workflow to obtain phylogenetic and population genetic data from whole genome sequences of body lice parasitizing New World ground-doves. Phylogenies from these data showed consistent, highly...
