...Harry Opfar Research Essay Viability of Marine Biology as a Major When deciding on a major for my college education, I had to find a field both in demand and it had to be a field I would like to spend the rest of my life in. I have always had a love of the animals in sea and several years ago had an opportunity to go to Sea World in San Diego. Recalling this trip and the recollection of seeing the dolphins and whales perform actually helped me make the decision to pursue a career in Marine Biology as a marine biologist. That brought me to the essence of this essay. How much education is required and does the marine biology field offer ample job opportunities and is there plenty of growth for future jobs? Also need to look at where those jobs are available, where I might have to move to. So I will first look at the education needed and the marine biology programs. I will then evaluate the job market now and in the future of this niche field. I will also exam the pay within this field and find out how the pay is derived as my research has shown that much of the money in this field of study originates different sources than a regular paycheck. There are several aspects to getting an education in marine biology. One need to look at the classes required and what schools are available, as well as where the best schools are located. A person majoring in the marine biology field needs to plan on taking many different types of animal biology and physiology classes. ...

...When I go to college and i want to start my studies to be a Marine Biologist. A marine biologist is a person who likes to study marine animals and sea life like whales, dolphins, crabs, all the way to microorganisms on plankton and the water. They work in private labs and i think that that sounds really cools and for it too be a career that sounds even cooler. I have always wanted to work with sea life or wanted to be a vet but then i realized that vet’s are always on call and can not ever have a break so i thought that that being a marine biologist was a good job to research for my paper and i have always loved the ocean and the beach and going with my family to the beach so I think that Marine Biology will be the right job for me because i get to live by the ocean and on a beach and i can finally live in a beach house. This is how i plan on becoming a marine biologist. After...

...swept by tidal currents (McEuen 1988). Some holothuroids are tropical reef dwellers (Uthicke 1997); others live in temperate or polar waters (Hamel and Mercier 1995). Even the depth at which these animals can be found varies greatly. Many species live within the intertidal zone, but a few sea cucumbers live deep in the ocean, some among hydrothermal vents (Smirnov et al. 2000). Regardless of the environment in which they are found, sea cucumbers have become highly adapted to life in that environment, especially in their reproductive cycles. Sea cucumbers can reproduce through sexual reproduction as well as asexual reproduction. Each mode of reproduction has several environmental factors that have been proposed to control its timing. This paper will first introduce the two types of reproduction found in sea cucumbers. I will then discuss some of the factors that have been shown to regulate sexual reproduction, specifically the processes of gametogenesis and spawning, and the factors assumed to control asexual reproduction. Finally, I will make a few suggestions as to directions that should be taken during future studies on external cues for reproduction in holothuroids. TYPES OF REPRODUCTION IN HOLOTHUROIDS Sexual...

...unintentional introduction of non-native species increases as well. Many of the deliberate introduced species often do not cause any problem as humans knowingly choose a suitable environment to fill an open ecological niche (3). However, on average, those unintentional introduced species often become pest by spreading widely or quickly, and cause harm to the environment, human health, other valued resources or the economy (2). As many of the accidental introduced species lack all or most their native, presumably coevolved, natural competitor or predator to control their growth proportion (3, 8). An example of the many accidental introduced pest species brought about by human activity in coastal zones worldwide which led to the disturbances of marine and estuarine ecosystem in Australia is Asterias amurensis, commonly known as Northern Pacific seastar, and it has been declared as animal pests under the Inland Fisheries Act 1995 (4). Introduction of A. amurensis and its population density The Northern Pacific seastar which is native to the coasts of northern China, Korea, Russia and Japan was first introduced to Australia (South Eastern Tasmania) in the early 1980s (5). The introduction was believed to be either as...

...review of a scientific journal article. Both types of writing ask you first to read and understand an article from the primary literature about your topic. The summary involves briefly but accurately stating the key points of the article for a reader who has not read the original article. The critique begins by summarizing the article and then analyzes and evaluates the author’s research. Summaries and critiques help you learn to synthesize information from different sources and are usually limited to two pages maximum. Actions to Take 1. Skim the article without taking notes: Read the abstract. The abstract will tell you the major findings of the article and why they matter. Read first for the “big picture.” Note any terms or techniques you need to define. Jot down any questions or parts you don’t understand. If you are unfamiliar with any of the key concepts in the article, look them up in a textbook. 2. Re-read the article more carefully: Pay close attention to the “Materials and Methods” (please note that in some journals this section is at the very end of the paper) and “Results” sections. Ask yourself questions about the study, such as: o Was the study repeated? o What was the sample size? Is this representative of the larger population? o What variables were held constant? Was there a control? o What factors might affect the outcome? 3. Read the “Materials and Methods” and “Results” sections multiple times: Carefully examine the graphs...

...Marine Mycology: An Overview of Pathogens, and Secondary Metabolites Introduction and History The golden age of marine mycology occurred from 1960-1990 with the research and discovery of most of the roughly 500 species of obligate marine fungi. Much of said research was conducted from 1980-2000; this 30 year period saw the report of nearly half of the marine fungal species currently known (Jones et al. 2009; Jones, 2011). That being said, marine fungi are vastly understudied and under rated in comparison to marine plants, animals, and other microorganisms; frequently they are omitted or only briefly referenced in marine biodiversity and ecology text books (Jones and Pang, 2012). The cladistics of marine fungi is currently in a state of flux, with new taxa being discovered as molecular techniques such as DNA and RNA analysis via polymerase chain reactions, and gel electrophoresis are implemented (Ald et al 2005). Even though fungus-like organisms such as oomycetes are not fungi, marine mycologists often study them as they perform similar functions, and until recently most had been classified as fungi based on their morphological similarities (Jones, 2011). These fungus-like organisms are eukaryotic, heterotrophic, zoospores, have chitin containing cell walls, and similar life cycles to fungi (Neuhauser et al. 2012). Conventionally terrestrial or freshwater species are also included in the marine fungal group as facultative species; this is due to their active ecological...

...The Study of Interactions between mussels and their Environment, as well as, between different species of intertidal organisms within a particular Intertidal Community By Arlene Reynolds California State Polytechnic University, Pomona, CA . Abstract. (The relationship between mussels and intertidal organisms within a particular community in the intertidal zone is a great example of the competitive exclusion principle. The alternative hypothesis for this study would be that there is a direct relationship between organisms due to interspecific competition, Introduction: California mussels (Mytilus californianus) are abundant where there is surf along the outer coast. They form massive beds, sometimes several meters across, on surf exposed rocks and wharf pilings in the upper middle intertidal zone and offshore, up to 24 meters deep. Like barnacles, mussels like to gather in dense clusters in the middle intertidal zone. Mussel beds are often large enough to be a home to many other creatures, like snails and worms. California mussel beds accumulate a gritty mixture of sand and bits of shell which provide a home for a various assemblage of animals including a number of polychaete worms, snails, crabs and a blackish sea cucumber. The Ochre sea stars are California mussels' main predator. Ochre sea stars affect the distribution of the mussels because the sea star generally occurs lower on the shore than the mussels and moves up to feed during high tide. Mussels are also eaten...

...BIODIVERSITY Biodiversity is the degree of variation of life. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet. Terrestrial biodiversity tends to be highest at low latitudes near the equator, which seems to be the result of the warm climate and high primary productivity. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in mid-latitudinal band in all oceans. Biodiversity generally tends to cluster in hotspots, and has been increasing through time but will be likely to slow in the future. Rapid environmental changes typically cause mass extinctions. One estimate is that less than 1-3% of the species that have existed on Earth are extinct. Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion—a period during which the majority of multi-cellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. The Carboniferous, rainforest collapse led to a great loss of plant and animal life. The Permian–Triassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the Cretaceous–Paleogene extinction event, occurred 65 million...

...English 1301, 9:05 MW P. Schmidt, HLN Paper# 3 Research Paper October 22, 2014 After the oil spill in Gulf of Mexico in 2010, a research by Douglas. B. Inkley shows that scientists are still assessing the effects of the estimated 170 million gallons of oil that flooded into the Gulf after the explosion of BP's Deepwater Horizon oil rig. The effects of oil spills can have wide ranging impacts that are often portrayed by the media as long lasting environmental disasters. Such perceptions are understandable as they are often fuelled by distressing images of oiled animals and other wildlife. More than 8,000 birds, sea turtles, and marine mammals were found injured or dead in the six months after the spill. In the months following the Gulf oil disaster, wildlife managers, rescue crews, scientists and researchers saw many immediate impacts of the oil impacting wildlife. Though oil is no longer readily visible on the surface, it isn’t gone. Scientists have found significant amounts on the Gulf floor, and the oil that has already washed into wetlands and beaches will likely persist for years. We likely will not see the full extent of impacts for many years, which makes creating and implementing successful restoration plans a serious challenge. Here is a list of some animals that were affected by the oil spill: * Sick Dolphins - As part of the official investigation into impacts of the Deepwater Horizon disaster, a team of scientists did comprehensive physicals on dolphins in...
