Testing a global standard for quantifying species recovery and assessing conser...
Grace, Molly K.; Akçakaya, H. Resit; Bennett, Elizabeth L.; Brooks, Thomas M.; Heath, Anna; Hedges, Simon; Hilton‐Taylor, Craig; Hoffmann, MichaelRecognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a "Green List of Species" (now the IUCN Green Status of Species). A draft Green Status framework for assessing species' progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e.,...
Cilia at the node of mouse embryos sense fluid flow for left-right determinatio...
Yoshiba, Satoko; Shiratori, Hidetaka; Kuo, Ivana Y.; Kawasumi, Aiko; Shinohara, Kyosuke; Nonaka, Shigenori; Asai, Yasuko; Sasaki, Genta; Belo, José A.Unidirectional fluid flow plays an essential role in the breaking of left-right (L-R) symmetry in mouse embryos, but it has remained unclear how the flow is sensed by the embryo. We report that the Ca2+ channel Polycystin-2 (Pkd2) is required specifically in the perinodal crown cells for sensing the nodal flow. Examination of mutant forms of Pkd2 shows that the ciliary localization of Pkd2 is essential for corr...
