One key signaling pathway known to influence neuronal migration involves the extracellular matrix protein Reelin.Typically, signaling of Reelin occurs via apolipoprotein E receptor 2 (ApoER2) and Samsung RS67N8210S9 American-Style Freestanding 65/35 Fridge Freezer very low-density lipoprotein receptor (VLDLR), and the cytoplasmic adapter protein di
Different nutrient supply brings about changes in leaf stoichiometry, which may affect growth rate and primary production of plants.Invasion of alien plants is a severe threat to biodiversity and ecosystem worldwide.A pot experiment was conducted by using three stoloniferous alien plants Wedelia trilobata, Alternanther philoxeroides and Hydrocotyle
A new Afrotropical species of Polynema Haliday, 1833 (Hymenoptera: Mymaridae), Polynema (Polynema) sagittaria van Noort & Triapitsyn, sp.n., is described and illustrated based on specimens collected in the Cape Floral region in south-western South Africa.This species is morphologically closely related to the Detergents recently described Po
BackgroundThe most primitive ornithischian dinosaurs were small bipeds, but quadrupedality evolved three times independently in the clade.The transition to quadrupedality from bipedal ancestors is rare in the history of terrestrial vertebrate evolution, and extant analogues do not exist.Constraints imposed on quadrupedal ornithischians by their anc
