Sperm experience intense and varied selection that dramatically impacts the evolution of
sperm quality. Selection acts to ensure that sperm are fertilization-competent and able to …

Sperm morphological variation has attracted considerable interest and generated a wealth
of predominantly descriptive studies over the past three centuries. Yet, apart from …

The free-living flatworm, Macrostomum lignano has an impressive regenerative capacity.
Following injury, it can regenerate almost an entirely new organism because of the presence …

How do animals regenerate specialised tissues or their entire body after a traumatic injury,
how has this ability evolved and what are the genetic and cellular components underpinning …

Regeneration-capable flatworms are informative research models to study the mechanisms
of stem cell regulation, regeneration, and tissue patterning. However, the lack of …

Sexual selection operates through consecutive episodes of selection that ultimately
contribute to the observed variance in reproductive success between individuals …

Macrostomum lignano is a free-living flatworm that is emerging as an attractive experimental
animal for research on a broad range of biological questions. One feature setting it apart …

Over the past decade, the free-living flatworm Macrostomum lignano has been successfully
used in many areas of biology, including embryology, stem cells, sexual selection …

Females of many different species often mate with multiple males, creating opportunities for
competition among their sperm. Although originally unappreciated, sperm competition is …

The regeneration-capable flatworm Macrostomum lignano is a powerful model organism to
study the biology of stem cells in vivo. As a flatworm amenable to transgenesis, it …
