BRIEF OBSERVATIONS ON THE SEMEN AND SPERMATOZOA OF CERTAIN PASSERINE AND NON-PASSERINE BIRDS
in ReproductionSummary.
The semen of some passerine and non-passerine birds was examined. That of passerine birds was thick in consistency and contained relatively few spermatozoa, while that of non-passerine species was more liquid in nature with many spermatozoa.
The two types of spermatozoa were found to differ considerably in morphology and activity, the passerine form showing a spiral configuration and a helical forward movement. The differences were also pronounced at the ultrastructural level.
Reproduction is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
