Barnacles Observation Essay

Observations
The several ecological factors discussed in the introduction were contrasted with the study site. The first site was analysed during high tide. Several aerate rocks occupied the rocky shore of the particular site. No presence of barnacles was noted.
There were several favourable abiotic and biotic factors within this microhabitat. These included tidal action, salinity, availability of 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 density that certain organisms posed. Periwinkles dominated the region increasing interspecific competition within the microhabitat.
Since the site was studied during high tide and was barely submerged, it indicated that perhaps the area was in the subtidal zone. Due to the barnacles’ constant need of submersion, this

Competition from both sandy and rocky ecosystems affect the niche of barnacles. Therefore, the barnacles observed within this site were very small along with visible competition around them. Populations were also very scarce and spaced out due to heavy competition and lack of suitable substrate. Tidal action was also limited due to the height of the rocks and the water levels exposed to the shores. The slope was also at a disadvantage due to the height of the rocks. Lesser level of water indicates lesser levels of nutrients thus the smaller barnacles. This study site provided an effective of a realised niche due to several biotic and abiotic

    Firstly, it is difficult to farm of carryout a forestry operation due to the steepness of this land. Furthermore, due to the lack of soil in many of these areas, the productivity of the land is low, as demonstrated through both CCAV and PRSIAV. Additionally the altitude of these climates, can make it difficult for most types of vegetation to grow successfully. This is particularly true on the wetter southern faces, where natives and gorse tend to take over. Subsequently, the most suitable land use is as conservation land and it isn’t easy or worthwhile to…

    Too much pollution in the ocean can make the seawater become too acidic. When the water is too acidic, some marine animals cannot survive. For some marine animals, acidic water reduces their ability to grow shells. “For instance, the thin shell of marine snails is easily eaten away by acid waters” (Levete, 15). The ability to not grow shells can decrease its chance of survival.…

    In the wild, B. splendens have a tendency to jump from water source to water source, especially when conditions in one become too stressful (Barrington 2013). As previously mentioned, the size of a betta aquarium affects the temperature stability of the water. Moreover, bettas in small aquariums will feel stressed, which may cause an increase in jumping behavior (Barrington 2013). This stress is caused by a lack of space to swim around. By jumping to another water source in their normal habitat, betta fish can escape shrinking or too small paddies or swamps.…

    The deep ocean is considered an extreme environment because of the low temperatures, high pressures, lack of oxygen and no sunlight. These conditions have caused the organisms which live there to evolve, often through unusual and unique adaptations, so they can live, reproduce, and thrive. An extreme environment is a place where humans normally do not live or could die there. There are organisms caused extremophiles that live there and are so well-adapted that they readily grow and multiply in order to survive. An example of an extremophile which lives in the deep ocean is the Anglerfish.…

    One of the ways these phosphates can occur is through decaying plant and animal remains. Also, phosphate can be found in fossilized bone and bird droppings.These are non-point sources, being harder to track down where they are because of all the possibilities of the origin. Phosphorus is a key element in growth for plants and animals. But, if the phosphorus level is too high in the drinking water it can be toxic.Phosphorus produces algae in the water and that algae can contaminate the system. Some algae can produce harmful chemicals that will harm plants or animals that are in the water,so it would not be a good idea to swim in water with algae or high phosphorus levels.…

    However, this is a difficult process because the lionfish are still capable of simply going back to the reef if relocated. One solution to the invasion is the hunting of Pterois voltans. Divers go down into the reefs and try to spear the lionfish. This is also difficult because they diver needs to have a clear shot at the lionfish so they don’t do any further damage to the reef. If a lionfish is found but is in an inopportune location, the divers are forced to let that lionfish stay there and try to find another.…

    The longer cooking time in the presence of gums was due to the limited availability of water to the starch granules by the competition with other macromolecules. It caused delay in the swelling and gelatinization of granules (Shittu et al. 2009). Chaisawang and Suphantharika (2005) explained that the presence of gum…

    Non –native species may also develop large uncontrollable population when intentionally or accidentally introduced into areas where they have no natural enemies to check their growth. Most problems with aquatic macrophytes arise when growth becomes too dense. In addition, certain non – native plant species are extremely aggressive (invasive) and can take over large areas of aquatic habitat. The floating mat of vegetation of macrophytes covers available sunlight from the water surface. The direct effect of this is low production in natural fish food (Phytoplankton – Zooplankton species) thus resulting in overall low fish productivity.…
