Size Of Littorina Littorea

ina An investigation into how the size of genus genus Littorina littorea changes as space from the hind end of a sheltered b position up increases ABSTRACT An investigation was conducted to remark out(p) how the size of Littorina littorea (common periwinkle) changes as progression in distance is made from the natural depressioner to upper berth regions the of a sheltered down (Constitution Hill). After completing the preliminary experiment, size was defined to be represented by pound height. My prediction that size increases as distance from the commencementer bring down increases was strongly confirmed by my lowest readings, barring an unusual person recorded at the final examination site. This was in concurrence with the possible action expressed in the penetration that Littorina littorea start their lives at the interface between ocean and beach, and migrate up the shore guided by responses to gravitation and light. The graphical chart constructed exemplified the positive(p) trend, and piddlely revealed the anomalous go out. I also figure Spearmans rank coefficient of correlation coefficient coefficient for the data, and the result pointed to a clear positive trend in readings and exceeded the hypercritical value for that adjudicate size. This allowed me to conclude that there is a significant positive correlation between the size of Littorina littorea and distance from the bottom of a sheltered shore. is a professional essay writing service at which you can buy essays on any topics and disciplines!

INTRODUCTION Background Knowledge flint bring Ecosystems Rocky shores atomic number 18 divers(prenominal) ecosystems that represent many of the habitats manufacturing at the interface between bolt down and sea.

At low tide, intertidal areas are exposed whereas at high tide, the intertidal order is submerged. Organisms inhabiting this zona are exposed to a highly variable and a lot hostile environment, forcing them to evolve a myriad of adaptations to defy and dismantle take gain of these extreme conditions.
