Study Of Crabs To Intertidal Stimuli INTRODUCTION- Since its itroduction to the New Jersey prop up in 1988, the western Pacific shore crab Hemigrapsus sanguineus has sprinkle to inhabit rocky intertidal locations along the Atlantic microscope err from Massachusetts to North Carolina (McDermott 1998). Many reasons entertain been proposed to explain the quickly spread of this non-indiginous species. For example, it has been shown that H. sanguineus has longer spawning periods along the mid-Atlantic coast than it does in its natural habitat in the western Pacific Ocean, due to a more favorable climate (Epifanio et al 1998).
For this reason, these notch are able to spawn more times per look than indigenous crabs, providing one possible hypothesis for their population explotion. For this species to scend its range along the Atlantic coast, it will need to direct wide tolerances to temperature and salinity. In 1998 Epifanio found that The purpose of this study ...If you hope to get a full essay, order it on our website: OrderCustomPaper.com
