Of numerous environment facts dictate the new shell profession pattern
New hermit crab shield duration research was submitted to a good Kruskal-Wallis decide to try, a non-parametric method that’s not established of normal delivery, based on SOKAL ROHLF (1995), from the a great 5% advantages top, to spot any potential difference in dimensions ranging from genders
In terms of almost every other hermit crab kinds, new broad geographical shipments away from Clibanarius vittatus (Bosc, 1802) was said by the its higher tolerance so you can bad ecological conditions owed to utilize out-of gastropod shells to protect its fragile abdomen (REESE, 1969).

Hermit crabs will often have specific choice to possess gastropod shell kinds (REESE, 1962; ORIANS Queen, 1964; BERTNESS, 1980). This preference is relevant to cover frameworks and you will dimensions (CONOVER, 1978). Hermit crabs hence consume large shells can also be better overcome to desiccation, thermal be concerned and you can predation (RITTSCHOF ainsi que al., 1995). A massive gastropod shell provides a generous interior city, which is beneficial having somatic growth (HAZLETT, 1981). (περισσότερα…)
