...Plankton Depletion and Environmental Effects Plankton is a term generally used for microorganisms or “floaters” that simply drift along wherever water currents take them. This includes zooplankton, algae, phytoplankton, and bacteria (G. Karleskint Jr. et al, 2010, p.464). But while it is common to see them as food for fish, they have other roles in nature what make them essential organisms in the delicate balance of our ecosystem. This paper will highlight the critical role of plankton as the organisms that make life on earth possible by describing the foundational role it plays in the food chain and in significant bio-chemical processes and discussing the negative effects it will give to the environment. I. Main Functions of Plankton in the Environment There are two main roles played by plankton in the environment. The first important role of plankton is in the food chain. Because of their microscopic size, they serve as food for other microorganisms, fishes and seal animals, which make-up 30% percent of the world’s entire intake of animal protein (J.H. Steele et al, 2009, p.8). Thus, we find plankton at the bottom of the food chain: zooplanktons eat other planktons for food, which in turn, along with phytoplankton and bacterioplankton, are food for fish and sea mammals, most of which eventually become food for human beings. Secondly, plankton plays an important role in the earth’s biochemical processes. Phytoplankton, for one, is responsible for the primary production...

And the jellyfish is plankton. 3) A subtidal is a part of the continental shelf stays under water regardless of the tides. 4) Low wave action means there is more particles, high wave action means less particles in the water. 5) White spotted sting ray, lobster, and the flounder. 6) Soft-bottom subtidal communities. 7) Soft-bottom shelf communities. 8) No they live in clumps together, marine biologists do not know why. 9) Detritus are the key food source. 10) Self-contained underwater breathing apparatus. 11) They collect food with tentacles or they actually swallow the sediment themselves. 12) Meiofauna either attach to individual particles of sediment, or move freely between them. 13) Because, deposit feeders are more common in muddy bottoms because of the presence of more detritus particles in the mud. Suspension feeders are more predominant in sandy bottoms, because there is a greater amount of water flow through the substrate. 14) Turtle grass is most commonly found in tropic areas, while eelgrass is more common in temperate areas. 15) They provide a place for other organisms to...

...Gammarus Duebeni The Gammarus Duebeni is an amphipod species found in freshwaters in North America. The Gammarus Duebeni is also commonly referred to as freshwater shrimp. This species’ preferred habitat is in the temperate region, specifically in clear, cold waters. This includes springs, ponds, streams, pools, and lakes. When the Gammarus Duebeni is found in rivers, they tend to be found near the edges of backwaters. The Gammarus Duebeni has a salinity tolerance and therefore can also be found in estuaries. The species cannot tolerate warm temperatures and will die in temperatures higher than 34C. The Gammarus Duebeni reproduces sexually. Mating occurs after the females molt and ovulate. The species is monogamous. Once the male makes bodily contact with a female, he “chases her, touches her with his divergent antennae and catches her by an appendage” (Sutcliffe). When the male ejaculates sperm, his female partner then puts it in her pouch. Once in there, her oviducts open and the eggs can begin to fertilize. After the mating, the males disperse while the females carry the eggs in their pouches until they hatch and the juveniles grow appendages. The gestation period is between one and three weeks and breeding usually takes place between April and November, depending on water temperatures. After the juveniles have grown appendages, they are released into the open water and the mother is relieved of her maternal duties. The offspring of some Gammarus Duebeni pairs can sometimes...

...Plankton are autotrophic, prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support. They inhabit oceans, seas, lakes, and ponds. All plankton ecosystems are driven by the input of solar energy. Zooplankton provides carbon to the planktic food web, either respiring metabolic energy, or upon death as biomass or detritus. They are the initial prey for almost all fish larvae as they switch from their yolk sacs to external feeding. They provide a crucial source of food to larger, more familiar aquatic organisms such as fish and whales. The common jellyfish feeds by collecting medusa, plankton and mollusks with its mucus bell nematocyst-laden tentacles and bringing the prey into its body for digestion. They are found throughout most of the world’s oceans. They do not have respiratory parts such as gills, lungs, or trachea. It is a small organism, so it respires by diffusing oxygen from water though the thin membrane covering its body. It is probably rare for these to live more than about six months in the wild. The hermit crab species have long, spirally curved abdomens, which are soft. The abdomen is protected from predators by a salvaged empty seashell carries by the hermit crab, into which its whole body can retract. As the crab grows in size, it has to find a larger shell and abandon the previous one. If the hermit crab cannot find a well-fitting shell, it will most likely be eaten. Sea cucumbers are echinoderms from...

...case are simple little issues such as emailing customer credit card numbers and such but I would have definitely have seen these issues but the lapse of these company have cost them security wise. The best way for organizations to strike the right balance between monitoring and invading their employees' privacy would be to evaluate each employees based on their activities. Have each employee make a report of their activities while the company is monitoring them as well the companies should put trust in their employees to report everything they're doing and when it is time to evaluate them cross compare what has been monitored and what the employees have reported. The consequence biased to one side would be if the company were to engage in just invading employee privacy there could be massive repercussions such as the company being sued etc. The other components are people security, establishing ethical behavior in the company, and managers taking the initiative to stop any leakage in the company. The human factor in is the stronger point in this situation its not the technology that's leaking information but the people the technology is just a tool to do so. The same goes for when it comes to monitoring and making sure that information is not leaked from the its the people who have to monitor to make sure that...

...Cancer borealis Cancer borealis ("Jonah crab") is found in the mid- to lower intertidal zone under algae and among rocks. This predator eats blue mussels and other invertebrates. The remains of this crab are often found in the upper intertidal zone, evidence of bird predation. Carcinus maenas Carcinus maenas ("green crab") is found under algae and small rocks, and it eats other invertebrates in the mid- to lower intertidal zones. This crab is native to Europe and is an invasive species. The green crab is smaller than the Jonah crab. Homarus americanus Homarus americanus ("American lobster") is a bottom-dwelling predator and scavenger. The American lobster is found throughout the Gulf of Maine, where it is commercially important. The lobster is found in rocky, subtidal habitats but, rarely, can be observed in lower intertidal pools. Idotea balthica This herbivorous crustacean, an isopod, feeds on a variety of algae including large rockweeds (Ascophyllum, Fucus). It is common in the mid- and lower intertidal zones but is hard to see because its color usually matches the algae it is feeding on. This behavior helps it resist predation by fish. Individuals vary in color from yellow to brown to deep burgundy. Semibalanus balanoides Semibalanus balanoides ("barnacles") are sessile filter feeders. Larvae settle in the spring and attach head down to the rock. They make heavy calcified plates, which protect them from predation and drying stress, and...

...service level, number of calls per employee, first call resolution, and transfer rate. By using the statistical report, it will help show the relationship between their performance and the organization standards or goals and it is easier to visualize. It can also be utilized by the managers to take necessary corrective actions if needed. The response time and service level can be measured by the monitoring how many calls are answered within how many seconds and total number of calls in a day is being answered. It is important to monitor the total amount of calls but we must consider the number of calls an employee is answering and should be reported to ensure that individual employee is properly assessed. This will also show if the employees are answering them promptly and not just a handful is answering the calls. The first call resolution (FCR) measures the individuals’ ability to accomplish the task in one transaction and not transfer the call. Transfer rate indicates how many calls have been transferred to another party to be handled. Monitoring the number of calls being transferred can identify if there are any performance gaps and training if needed (Reynolds 2012).

...Currently Riordan Manufacturing has several different offices and each office is using a different type of system, but there is not a central system that monitors each of the satellite offices and their production. To assist Riordan become more efficient, they will need to implement a central system to monitor both individual and overlapping system usage. They should create a Data Center in the corporate office that monitors all of the current systems in place. This will allow Riordan Manufacturing to understand how their business is functioning and how application are used more often and which are not utilized enough, helping to determine if they should upgrade or discontinue the use of a system. Each department uses different applications; some of the applications interface with one another and other are stand alone. Riordan also currently has a lot of manual processes, for example how they submit daily inventory records. With the overall updates that our team has posed have more automation will assist Riordan to increase their production and accuracy. We can implement an application that can be used by all of the centers in order to maintain the inventory across the board so the managers are able to see what is in high demand in specific locations. Having an overall view of the inventory will be beneficial to the entire company. If the marketing department has he ability to see the inventory usage then they will know where they need to market certain products better. We...

...Elias N. Khan Prof. Session CRJ 115 7 December 2015 Packet Sniffers: A Bittersweet Software Packet sniffing software is a controversial subject and a double-edged sword. It can be used to analyze network problems and detect Internet misuse. But at the same time, it allows hackers and people with malicious intention to "sniff" out your password, get your personal information, and invade your privacy. That is also why securing and encrypting data is so important. In this paper, the definition of packet sniffing will be introduced and several functionality and possible uses of packet sniffers will be explained. Also, information on how to protect against sniffers and man-in-the-middle attacks will be provided. An example of a packet sniffer program, Wireshark, will be given, followed by a case study involving the restaurant chain Dave & Buster's, which will show the negative consequences that can occur when organizations are not aware of the threat of packet sniffing by hackers. A packet sniffer is "a computer program or a piece of computer hardware that can intercept and log traffic passing over a digital network or part of a network" (Connolly, 2003). Packet sniffers are known by alternate names including network analyzer, protocol analyzer or sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer (Connolly, 2003). As binary data travels through a network, the packet sniffer captures the data and provides the user an idea of what is happening...

...IS4670 Unit 7 Assignment 1: Overcome Difficulties of Network Monitoring One of the initial ideologies behind most organizations' network security practices is still "defense in depth," which is performed using a variety of security controls and monitoring at different locations in an organization's networks and systems. As part of a defense-in-depth scheme, it has become commonplace for organizations to build enterprise security operations centers that bank on in part on monitoring the tremendously large volumes of network traffic at the perimeter of their. There has been a recent style toward increased investment in and reliance on network monitoring in order to streamline sensor deployments, decrease cost, and more easily centralize operations. At the same time, the idea of a well-defined defensible perimeter is being challenged by cloud computing, the insider threat, the so-called advanced persistent threat problem, and the popularity of socially-engineered application-level attacks over network-based attacks. Commonly, network and security practitioners hear that the start of any network-centric project is to baseline the network. What exactly is this supposed to mean? Simplistic approaches concentrate on bandwidth utilization over time, typically focusing on spikes and troughs. Some try to describe traffic in terms of protocols and port numbers. More advanced approaches try to classify traffic according to flows or even content. Regardless, there is no single accepted...

...Administrative Control versus Trust Unit 8 Exercise 1 ITT Technical Institute Floyd Washington Jr. May 21, 2015 As an administrator you must set up guidelines over a network to prevent the malicious intent of bad users. This is why the administrator must implement Administrative Control. Administrative Controls are the policies, guidelines, procedures and standards that protect the overall integrity of the company’s computer network. This is when the company’s IT Professionals take every precaution possible to ensure that their computer network is secure and free of viruses that can cause the network to crash. Administrative control is one thing, but too much control can hurt a business in many ways. Too much control over a company’s network can restrict user from attaining much needed information. Therefore, an administrator must allow some users in the company full use of the company’s network without any restrictions. As a network administrator you must choose the people carefully that you allow full access to your company’s network. They must have solid instructions for the sites they are to visit. Administrative controls can have a great influence on the decision making of the entire company workforce. Without Administrative controls there can and probably will be serious liabilities formed against the company you work for. Most computer networks today will require that users use an authentication process, which means that the network is password and PIN protected...
