U. SHEFFIELD (UK) — Critically
endangered birds often fail to reproduce in captivity or the wild, but new
methods may make it easier for scientists to keep these species going.
The newly developed methods
allow experts to tell the difference between infertility and very early embryo
death—something that has never been done before in endangered species.
Researchers from the
University of Sheffield’s department of animal and plant sciences believe their
new method of assessing egg fertility, ensuring pairs are sexually compatible,
and the males are producing enough sperm could save bird species on the brink
of extinction.
