| Summary: | These data are associated with a study that tests the hypothesis of thermal plasticity in the rigid setae of the second limb of Daphnia. The data are body size and length measurements (mm) of three limb setae (limb 2; endite 2). The second seta is often called the "rigid" seta because it is heavily chitinized. In all, 300 specimens of Daphnia (including Daphnia umbra and Daphnia galeata) were dissected from four sets of clonal thermal transfers and seasonal variants from nature. Specimens of D. galeata were cultured under identical conditions save temperature (10 and 20◦C). Clonal neonates were reciprocally transferred across temperature regimes to determine the degree of postnatal plasticity. Table of measurements from experiments to test the hypothesis of thermal plasticity of the rigid seta of the second endite, second limb, in Daphnia. Daphnia galeata was collected from Glen Haven Park, Irondequoit Bay, Lake Ontario, Rochester, NY and Guelph Lake, Ontario, Canada. The columns are: body (body length from lateral view of adult females in mm), seta 1 length (mm), seta 2 length (rigid seta), seta 3 length (mm), group number in the manuscript, temp (growth temp warm >20C or cold <10C), source (wild type from nature, F1 or multigenerational culture), and transfer (life stage of transfer to temperature treatment).Funding provided by: National Science FoundationCrossref Funder Registry ID: http://dx.doi.org/10.13039/100000001Award Number: DEB-0331095 Midsummer and Midwinter samples of Daphnia galeata were collected by a zooplankton throw net (30 cm dia., 200-250 um mesh size) from Guelph Lake, a eutrophic reservoir in Guelph Ontario, Canada, and Lake Ontario near Rochester, New York. Midwinter specimens were collected when the lake was covered with ice. We used ethanol preserved specimens of Daphnia umbra from a pond on the northern Melville Peninsula, Nunavut, Canada in August. To quantify the seasonal differences in seta lengths, midsummer and midwinter specimens (i.e., the coldest and warmest lake ... |
