Egg loss can occur at any point during the reproductive period. Several past studies document egg loss across a variety of crustaceans. The mangrove tree crab is expected to experience high egg loss, due to it’s constant climbing on tree limbs. Egg production and loss provide valuable insight into the reproductive physiology and the mangrove tree crab and its ecology as an important part of the mangrove ecosystem. (Boudreau et al. 2012). This species is also currently expanding it’s range due to climate change, and egg loss will factor into the rate of population growth in northern regions of its expanding range. Secondarily, we also look for evidence of sperm limitation, when there is insufficient sperm to fertilize all eggs produced by the females. If sperm limitation is occurring, the reproductive potential of a population would be limited, and could hamper its ability to keep pace with environmental changes. Addition, sperm limitation has the potential to change the mating dynamics of decapod crustaceans in a number of ways (Wedell 2002).
