Data from: Beyond animals and plants: dynamic maternal effects in the fungus Neurospora crassa

Kolea C. K. Zimmerman, Daniel A. Levitis & Anne Pringle
Maternal effects are widely documented in animals and plants, but not in fungi or other eukaryotes. A principal cause of maternal effects is asymmetrical parental investment in a zygote, creating greater maternal versus paternal influence on offspring phenotypes. Asymmetrical investments are not limited to animals and plants, but are also prevalent in fungi and groups including apicomplexans, dinoflagellates, and red algae. Evidence suggesting maternal effects among fungi is sparse and anecdotal. In an experiment designed...

Data from: Gene duplication and divergence produce divergent MHC genotypes without disassortative mating

Donald C. Dearborn, Andrea B. Gager, Andrew G. McArthur, Morgan E. Gilmour, Elena Mandzhukova & Robert A. Mauck
Genes of the major histocompatibility complex (MHC) exhibit heterozygote advantage in immune defence, which in turn can select for MHC-disassortative mate choice. However, many species lack this expected pattern of MHC-disassortative mating. A possible explanation lies in evolutionary processes following gene duplication: if two duplicated MHC genes become functionally diverged from each other, offspring will inherit diverse multilocus genotypes even under random mating. We used locus-specific primers for high-throughput sequencing of two expressed MHC Class...

Data from: Dissolved organic carbon modulates mercury concentrations in insect subsidies from streams to terrestrial consumers

Ramsa Chaves-Ulloa, Brad W. Taylor, Hannah J. Broadley, Kathryn L. Cottingham, Nicholas A. Baer, Kathleen C. Weathers, Holly A. Ewing & Celia Y. Chen
Mercury (Hg) concentrations in aquatic environments have increased globally, exposing consumers of aquatic organisms to high Hg levels. For both aquatic and terrestrial consumers, exposure to Hg depends on their food sources as well as environmental factors influencing Hg bioavailability. The majority of the research on the transfer of methylmercury (MeHg), a toxic and bioaccumulating form of Hg, between aquatic and terrestrial food webs has focused on terrestrial piscivores. However, a gap exists in our...
