Growth of the Land Crab Cardisoma Guanhumi in Puerto Rico
Main Article Content
Abstract
The land crabs’ integument release process during molting represents a moment of vulnerability due to the desiccation risk and the lack of water availability for the molting. The aim of this study is to ascertain Cardisoma guanhumi growth increase. A marking-recapture study was conducted to estimate crab growth. The study was carried out in six Puerto Rico locations. It was found that growth increment is 8.7%, which is larger than previously reported; this increment varies among study sites. Forests with higher vegetation coverage and lower edge density favor a larger growth increment. Crab´s habitat conservation is essential for the species´ survival.
