1682por Bennett, Hayley M, Lees, Kristin, Harper, Kate M, Jones, Andrew K, Sattelle, David B, Wonnacott, Susan, Wolstenholme, Adrian J“…Maximal activity of RIC-3 may be cell-type dependent, so neither mammalian nor invertebrate proteins is optimal in amphibian oocytes. We cloned the X. laevis ric-3 cDNA and tested the frog protein in oocyte expression studies. …”

1692por Trebitz, Anett S., Hoffman, Joel C., Grant, George W., Billehus, Tyler M., Pilgrim, Erik M.“…We found barcode libraries largely complete for extant and threatening-to-invade vertebrates (100% of reptile, 99% of fish, and 92% of amphibian species had barcodes). In contrast, barcode libraries remain poorly developed for precisely those organisms where morphological identification is most challenging; 46% of extant invertebrates lacked reference barcodes with rates especially high among rotifers, oligochaetes, and mites. …”
