  • Hippca Habitat Destruction

    marine habitat for the whale. Also, the human race can make an effort to reduce pollution and its impact upon marine life. If the human race were to significantly reduce pollution into the aquatic environment we could not only promote and provide a more natural and sustainable ecosystem for the whales but for all aquatic species that inhabit the ocean. Climate change will continue to be an augmenting issue that will…

  • Water Quality In Lake Tahoe

    Lake Tahoe is located in the Sierra Nevada mountain range in the northeastern part of California, boarding Nevada. It is well known as a tourist attraction for its great depth and clear cobalt blue waters located at high elevation. The combination of its depth, low ratio of watersheds to lake surface area, and its granite rock geology has lead to the creation of a low fertile and high transparent monomictic lake. Its also unique in that it doesn’t fully mix from top to bottom every year, lake…

  • River Flow Alteration Essay

    guiding principles for management. The development of flow assessment methodologies is used for prescribing environmental flow requirements. Environmental flow regimes in streams and rivers are the primary determinant of the structure and function of aquatic and riparian ecosystems (Poff et al., 1997; Hart and Finelli, 1999; Bunn and Arthington, 2002). Environmental flows are defined as the ‘quantity, timing and quality of water flows required to sustain freshwater and estuarine ecosystems and…

  • Spatial Variability In Plankton Communities

    Spatial variability in local plankton communities can have large effects on the composition and diversity of the secondary production with in an area. Therefore, it is important for scientists to study the factors that affect plankton community’s abundance, diversity and dominance. In this study multiple physical and biological factors were observed in order to examine how surface plankton communities varied with distance from shore in the nearshore environment of the Southern California Bight.…

  • Invertebrate Diversity

    This study examined the effects of physical factors on diversity in freshwater environments by observing invertebrate diversity in riffles and pools in a freshwater stream. It was hypothesized that differences in invertebrate diversity between riffles and pools would be due to physical factors in the environment. To test this hypothesis, invertebrates were collected from each environment and classified by their taxa, and Shannon-Simpson indices were produced from these data to analyze the…

  • Shark Culling Research Paper

    Shark culling is a state government implemented policy in which sharks within the vicinity of a beach can be legally killed through shark nets or drumlines or a combination of the two. Drumlines are unmanned buoyant drums anchored one kilometre of a beach's shoreline. In between the drums are ropes with hooks. Drumlines are baited so that if a shark is swimming in the vicinity of a beach it would be attracted to the bait and not humans. Each state has different policies on drumlines depending on…

  • Importance Of Gut Content Analysis Of Fish

    ecological components that included behaviour, condition, habitat use, energy intake and inter/intra specific interactions, etc. Accurate description of fish diets and feeding habits also provides the basis for understanding trophic interactions in aquatic food webs. Conceptually, trophic relations of fishes begin with foods and feeding behaviour of individuals or species. Diet composition analysis can be used to evaluate effects of ontogeny, or the establishment of exotic species (Gelwick &…

  • The Pros And Cons Of Invasive Species

    The mulch is usually requested from Madison Park. It is composed of chipped, compost, shredded leaves, manure and straw. The decomposers in mulch will break down the organic matters in mulch and convert it into inorganic nutrients that the plants need. First of all, we cleared the area by removing the invasive species and weeds. Then, we put coffee bags to cover the whole area and wait for mulching. When people look closer to the mulch, people can often see vapor is releasing from the mulch…

  • Basic Concepts Of Land Use And Land Cover Change

    CHAPTER TWO LITERATURE REVIEW 2.1 Basic Concepts of Land-Use and Land-Cover Change According to (FAO (Food and Agriculture Organization), 2000; Gregorio, 2005) land cover refers to the biophysical cover of the earth surface or land for instance vegetation cover such as forest, shrub/bushland, and grassland and water. Whereas land cover can be defined as the attributes of the earth’s land surface covered by vegetation, desert, water bodies like lake, sea, ocean, bare soil and ice (Chrysoulakis…
