Intertidal zone

An ANOVA was then run on this graph to determine whether size is influenced by tidal zone. A scatter plot was also created, with cockle size plotted against distance. A similar graph was then created but with age plotted against tidal zone instead of size. These two graphs included an R^2 value to help determine if there was significant statistical trend in the scatterplots. Results: Cockles were more abundant in low tide with abundance increasing towards high tide. Feeding rates were lowest at low tide with an increase in mid and high tidal zones. There was a positive correlation between size and length of cockles. Large cockles have a higher frequency at low tide and size decreases down the intertidal gradient to the high tide line. Similarly, the age within the intertidal gradient increases from the low to high tidal zone. All these findings are outlined by the graphs and tables…

have been able to observe marine organism in the clade Littorinimorpha in the three tides zones high, mid, and low each have their own ecological niche for marine organisms. But there is some marine life that are able to live in patchiness within zones and thrive in more than one. The high intertidal zones are home to marine life that are more tolerant to air, like barnacles (Ricketts et al. 1968). The mid zone includes higher low water and lower low water, which can be indicated by limpets…

Rocky intertidal zonation at Lawrencetown Beach Introduction Nova Scotia has an extensive coastline with varying degrees of exposure. The intertidal zone (littoral zone) is where the ocean meets land and around Nova Scotia’s coast this zone is highly diverse, from salt marshes to mudflats and rocky shores. The intertidal zone is the area that is exposed to air at low tide and submerged by water at high tide and the species that are located here need to tolerate various levels of exposure. The…

majority of the day, a contributing factor in their pattern of zonation. The mobile nature of Green Chiton also allows it to avoid detection by predators. It allows the organism to move to sheltered areas during the day. Its ability to move is a structural adaptation as it does so using its muscular foot, but its use of this to move to sheltered areas is a behavioural adaptation. Its ability to move would allow it to thrive in all areas of the intertidal zone and therefore does not contribute…

crabs are an important role in salt-marsh ecology. As their burrowing and feeding helps to keep mud marshes clean for other organisms such as mangroves (Edc.uri.edu, 2016). Ghost crabs have a pale body colour in which can almost be seen as invisible to prey when walking over sand. Ghost crabs burrow holes at a 45 degree angle of a 1-2 centimetres width in order for shelter from the sun. This crab possesses the unique ability to store oxygen in air bags which gives it the ability to survive…

Rhizophora mangle the red plague Mangroves are a predominant form of vegetation that can be found in intertidal zones of tropical estuaries, lagoons, sheltered shorelines and in subtropical coastlines (Allen, 1998). Mangroves are trees and shrubs that have adapted to living in saltwater environments. They are propped up, out of the water, by dense, tangled roots that allow them to obtain oxygen in oxygen poor sediments. Their roots also allow the tree to remain supported during the rise and…

Materials and Methods The sampling of the Gambusia holbrooski was done in Hennington Pond at FIU. The class was divided into five groups each tasked with obtaining thirty samples of mosquitofish. These samples were obtained randomly using a landing net and a bucket of water that contained water from the pond to put the fish. The collected fish were measured and their length recorded (in mm) from the apex of the lower jaw towards the posterior end. The measurement was done using a small ruler…

Comparing the Intrinsic Similarities and Characteristic Differences in Arthropods and Mollusks. Coastal regions possess a unique characteristics in which all plant and life forms have to adapt in order to be able to survive in such regions. One major characteristic of these regions is due to the constant wave motion of the seas in coastal regions. Hence, life forms such as Arthropods and Mollusks, predominant life forms present in these coastal regions, adapt and specialize to be able to thrive…

The broad similarity between two articles Ehlers, Worm & Reusch (2008) and Campanella et al. (2013) is that both papers emphasized the importance of the genetic diversity of Zostera marina, an ecologically important plant for coastal ecosystem to survive adverse environmental conditions arising from climate change, catastrophic events (storm, heat waves) and anthropogenic activities (pollution, eutrophication, habitat destruction etc). Ehlers et al. (2008) talked about the effects of temperature…

nutrients and lack of diversity within the competition of space and lack of predators. Despite these favourable characteristics, certain limiting factors prevented the organisms from inhabiting the site. Perhaps the most crucial limiting factor was the substrate. Since barnacles secrete an adhesive onto solid rock to withstand high velocity waves and remain sessile, a porous substrate disabled the organism to effectively attach itself to its substrate. Another factor was the competition…
