Explain about chthalamus

The realised niche of Chthalamus is reduced from its fundamental niche and it is limited to the upper tidal zone

Lower  limits

  • Out-competed by Balanus for space on rocks/ Balanus larvae settle earlier and so occupy space on rocks CRLE
  • Weakness in either concept CRLO
  • Predators such as whelks inhabit the lower intertidal zone and may preferentially predate Chthamalus, excluding them from this area. CRL

 Upper  limits: as for fundamental niche but no comparison with other species.  CU  Eg, Chthalamus has a high physiological tolerance to dehydration/desiccation so can survive in upper tidal zone.
