ImpactModerate impact

The conversations suggest the research advances understanding of how ecology shapes physical traits, hinting at moderate influence.

Abstract in brief

  • Sexual size dimorphism (SSD) is common in ungulates, with males often being larger and having bigger weapons due to polygyny, but not all species follow this pattern.
  • The study on hippopotamuses shows they have limited differences in overall body size between sexes, but males have significantly larger jaws and canines, indicating selection for weapons rather than size.
  • The hippos' aquatic lifestyle and unique physiology seem to limit body size differences, making weapon size the primary trait under sexual selection, which highlights how ecology and physiology influence SSD.]

resulta que los hipopótamos sí tienen dimorfismo sexual! pero es tan sutil que no permitiría determinar el sexo de individuos sin capturarlos con miras a esterilización https://t.co/RTNuL4Z1I9

Loved the backstory to this recent publication on sexual size dimorphism in hippos by @GW_Shannon, @LineCordes, et al - https://t.co/75PJb61enW "We used 60-year-old notebooks to find out why male hippos have bigger tusks than females" https://t.co/fRw8OzATPf @GW_Shannon
