...the group’s individuals learn what they need to know to be able to teach their part to the other groups. This is done so that a teacher does not always have to be right there all the time. The leader of the group should be the most mature of the group. Step three: Give each group a separate assignment that is related but not the same as the other groups. The groups will be as follows. Group one will be given the task of researching the animals of the salt marsh. Group two will be given the task of describing what a salt marsh is and where it is located. Group three will be given the task of describing the tides, the changes in the tides, and the effect it has on the salt marsh ecosystem. Group four with research and describe the salinity of the salt marsh and how and what makes it change. Group five will be given the task of researching the plants of the salt marsh Step four: Hand out a rubric with what information each assignment should know at the end. Once the assignments have been given allow the students time to research and write a rough outline for their presentation. Make sure that the students have access to the...

...must start with a “hook”. Something that will pique their interest in the topic and make them want to learn more. For the purposes of this paper, the concept at hand is the interdependence within ecosystems. The ecosystem the students will be studying is saltwater marshes, plants and animals. Teaching this concept in the classroom will be most successful using a combination of a Jigsaw approach coupled with a STAD (student team achievement divisions) approach. The key elements of both the Jigsaw cooperative learning method and the STAD method include breaking students into racially, socio-economically, gender and differing ability groups. In terms of the assignment of salt water marshes, there are three main areas of information to be assimilated: tidal changes, plants and animals. The initial step, in accordance with the STAD model, would be to provide a basic lecture of saltwater marshes, covering facts and disseminating information on each of the three main topic areas. This could include a basic lecture/presentation that included pictures, written information, and other various forms of initial information on the subject. Following the JIGSAW model and supposing a group of 30 students in a classroom, the process would then include breaking students into ten diverse groups, assigning each group of ten one of the three areas of research: tidal changes, plant life and animals. In accordance with the Jigsaw method, each group would then go into their “expert” group and study...

...Biotic Component Paper Biotic Components Paper In this paper I will conduct research on the Bolsa Chica Wetlands that are located in an area of lowlands in Orange County California, adjacent to the city of Huntington Beach. The area is managed by the National Marine Fisheries Service (NMFS), whose mission is to” protect and enhance; migratory shorebird, seabird, waterfowl overwintering habitat; protect natural habitat for shorebirds and seabirds; protect nesting and foraging conditions for threatened or endangered species” The Bolsa Chica Conservancy (BCC) is a local volunteer organization that assists in maintaining the area. Its goals are to ensure the preservation, restoration, and enhancement of the area (2010). This dynamic, yet fragile, ecosystem has been preserved since 1965, flourishing under diligent and careful management. Coastal ecosystems include marshes, coastal waters, estuaries, and lands located at the lower end of drainage basins, where rivers and streams meet the sea or ocean (United States FWS, 2010). These complex ecosystems are composed of biotic communities; plants, animals, birds, and microbes, and the abiotic community; nonliving, chemical, and physical. According to Wright (2008) the type of biotic community found in a given area, is largely determined by the abiotic factors, such as the amount of water, climate, the salinity, or type of soil. Bolsa Chica has a wealth of plant and animal species including Sea Lettuce, Pickleweed...

...Evaluation of the Ecological Restoration Projects at The University of California, Santa Barbara’s Lagoon Authors: Matthew Edmiston Cat Bradley Chris Anderson Abstract: The University of California, Santa Barbara’s lagoon has undergone several ecological restoration projects over the past two decades. Some efforts have proven to be beneficial, while others still need improvement. This paper addresses and evaluates five different locations around the lagoon, the various restoration projects at the sites, and what more could be done at each habitat in order to assess the ecological restoration efforts in the UCSB Campus Lagoon area. The sites addressed are the San Nicolas degraded wetlands, Campus Point, the coastal sage scrub, Manzanita Village and the bioswales. Overall, each of the sites have finished going through extensive restoration, with techniques such as solarization and re-introduction of native species. Most of the ecosystems are now returned to their pre-disturbed state, but continued efforts are needed to preserve the locations. 1.0 Introduction: The term “ecological restoration” is generally defined as “the return of an ecosystem to a close approximation of its condition prior to disturbance” (NRC Report, 1992). Although this term is often oversimplified, it includes a complex web of cultural, social and political aspects as well as environmental aspects. Due to its complexity, and in many cases, the many competing jurisdictions involved, it is often...

...THE IMPACT OF CLIMATE CHANGE ON THE UK HEALTH By Name Course Professor’s Name Institution State Date In the modern society, human practices influence the environment in a negative way. Specifically, industrial, agricultural and domestic activities exacerbate the ecological system, affecting humans, animals, and plants. Greenhouse emissions, agricultural chemicals, and domestic toxics cause air and water pollutions that affect human health. Therefore, climate change is an imperative factor that needs proper redress in protecting the health of the UK citizen. Accordingly, this paper examines the holistic health experience associated with climate change. Particularly, the paper explores climatic changes such as pollution and flooding and their direct influence in human health through infection and diseases. Climate change in the twenty-first century plays a vital role in the issue of public health. The rapid population growth rate of the modern world endangers human development and weakening the capacity of the contemporary communities to adapt and respond to climate change. The interrelation of population and climate changes lies in mitigation and adaptation. For this reason, people should reduce the levels of greenhouse emission and subsequently decrease the vulnerability of the population to the effects of climatic change. The science of climate changes integrates profoundly with the dynamics of the population. For example, the mass...

...March 2, 2013 – The Everglades Flood Control and Restoration: A Century of Disaster OUTLINE ABSTRACT ……………………………………………………………………………………………… Before drainage of the Everglades began over a century ago, the wetlands of southern Florida were an interconnected hydrological assortment of lavish freshwater lakes and streams, cypress swamps, secluded estuarine lagoons, freshwater sloughs, tree islands, wet prairies, and mangrove swamps spanning 3.6 million hectares. After a century of intrusion, the daunting task of understanding, fixing, maintaining, and regaining a sustainable, natural Everglades-type ecosystem in South Florida is monumental. The area south of Lake Okeechobee now has a human population of over four million people, with greedy agricultural and urban demands for more water and more space. Therefore, several uphill battles have ensued. The conceptual plans for restoring this ecosystem, currently on record, are all extremely expensive to implement. A more thorough definition of the environmental and societal objectives and measures of success are required. How the ecosystem will respond to the return of a more natural hydrological pattern is uncertain, but needs to be addressed as the expected and desired outcome through measures of performance. The critical level of deterioration of the Everglades has created a crisis-management atmosphere instead of a full spectrum response and future prevention methodology. The political and social aspects of the Everglades...

...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...

JEYADOSS* Department of Chemistry and Biosciences, Srinivasa Ramanujan Centre, SASTRA University, Kumbakonam - 612 001 (India). (Received: September 03, 2010; Accepted: October 11, 2010) ABSTRACT A field experiment was carried out during the chithiraipattam (April-May) in India in 2010 to study the effects of foliar applications of different concentrations of seaweed liquid fertilizer (SLF) of Sargassum wightii on growth, biochemical constituents and antioxidant enzymes of Helianthus annuus L. to explore the possibilities of reducing or avoiding chemical fertilizers and to obtain the highest growth and productive parameters. The foliar spray was given twice in 15days interval at two concentrations (2.5%, 5.0%) of SLF. The aqueous extract of Sargassum wightii was found to promote almost all the parameters such as shoot length, root length, leaf length, leaf breadth, fresh weight, dry weight and number of leaves. The biochemical contents such as chlorophyll a, b, total chlorophyll, carotenoids, carbohydrate, total phenols and antioxidant enzymes such as catalase, peroxidase and glutathione peroxidase (GPX) were also found to be higher in the leaves. Among the two concentrations 2.5% was found to produce better results in almost all the parameters. The results revealed that foliar application...

...Food Science Food Packaging—Roles, Materials, and Environmental Issues KENNETH MARSH, PH.D., AND BETTY BUGUSU, PH.D. The Institute of Food Technologists has issued this Scientific Status Summary to update readers on food packaging and its impact on the environment. Keywords: food packaging, food processing dvances in food processing and food packaging play a primary role in keeping the U.S. food supply among the safest in the world. Simply stated, packaging maintains the benefits of food processing after the process is complete, enabling foods to travel safely for long distances from their point of origin and still be wholesome at the time of consumption. However, packaging technology must balance food protection with other issues, including energy and material costs, heightened social and environmental consciousness, and strict regulations on pollutants and disposal of municipal solid waste. Municipal solid waste (MSW) consists of items commonly thrown away, including packages, food scraps, yard trimmings, and durable items such as refrigerators and computers. Legislative and regulatory efforts to control packaging are based on the mistaken perception that packaging is the major burden of MSW. Instead, the U.S. Environmental Protection Agency (EPA) found that approximately only 31% of the MSW generated in 2005 was from packaging-related materials, including glass, metal, plastic, paper, and paperboard—a percentage that has remained relatively constant since the 1990s...

...application must be successful and effectiveness high. As some oil would come ashore, discussion remains on what effectiveness is required to significantly reduce the shoreline impact. A major issue is the actual effectiveness during spills so that these values can be used in estimates for the future. The second motivation for using dispersants is to reduce the impact on birds and mammals on the water surface. The benefits of using dispersants to reduce impacts on wildlife still remain unknown. The third motivation for using dispersants is to promote the biodegradation of oil in the water column. The effect of dispersants on biodegradation is still a matter of dispute. Some papers state that dispersants inhibit biodegradation others indicate that dispersants have little effect on biodegradation. The most recent papers, however, confirm that inhibition is a matter of the surfactant in the dispersant itself and the factors of environmental conditions. It is clear, on the basis of current literature that the surfactants in some of the current dispersant formulations can inhibit biodegradation. No...

...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...
