Mohammad Andres Vega Biología Costa Rica land crabs leaf litter burrow counts Gecarcinus quadratus The land crab Gecarcinus quadratus is an engineering species that controls nutrient cycling in tropicalforests. Factors regulating their coastal distribution are not fully understood. We quantified land crab distributionduring the dry season at Sirena Field Station in Corcovado National Park, Costa Rica, and found that land crabburrow density decreases with increasing distance from the ocean. Leaf litter depth and tree seedling density arenegatively correlated with land crab burrow density. Burrows are strongly associated with sand substrate andburrow density is comparatively low in clay substrate. Results suggest that G. quadratus is limited to a narrowcoastal zone with sand substrate, and this distribution could have profound effects on plant community structure.Rev. Biol.
