• ovulation

  • The epicranium bears most of the main sensory organs, including the antennae, ocelli, and the compound eyes. (wikipedia.org)
  • content
  • The aims of this work were to measure the AEA content and to characterize the main AEA metabolic pathway in the bovine oviduct and determine how these change through the oestrous cycle. (jove.com)
  • female
  • We refer to sexual conflict in the narrow sense as the view that selection acts on females only to reduce the direct costs of mating interactions with males (costs paid by the female in either viability, fecundity or offspring survival). (royalsocietypublishing.org)
