...Biology Period 1 The Effect of Varying Light Intensities on the Location Preference of Brine Shrimp Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will prefer a chamber with significant light intensity because they need light in order to hatch and develop. Null Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will not have a preference. Procedure: The brine shrimp were placed in the long tube choice chamber. Four quadrants were labeled and covered with varying materials to block out a certain amount of light. Quadrant 1 was in full light with 62 FC, quadrant 2 was covered in a material that allowed 29 FC of light, quadrant 3 was exposed to 12 FC of light, and quadrant 4 only had 1 FC, or almost no light exposed. Brine shrimp were introduced to the choice chamber with a 60 mL syringe and then observed for several minutes before recording results. Results:...

...suggested that the brine shrimp’s preference for green light is due to their food sources being predominantly green in colour. However brine shrimp are non-selective filter feeders who have no preference in what food they consume as they only consume what food is available to them at the time. This raises the question as to why the brine shrimp have an apparent preferred wavelength of light in this set of results. It could be assumed that the brine shrimp were raised in an environment where an area with a similar light colour to the green light used in the experiment contained more mates, was a safer environment and had a greater resource of food. As the brine shrimp move towards the light they would be more visible to predators in their...

...The Effect of Calcium on Hatching Brine Shrimp Eggs science fair project will investigate how the addition of various amounts of calcium to brine shrimp eggs will affect their hatch rates. I was drawn to this area because I have an interest in how several outside factors can affect the nature of a process. My hypothesis for this lab is that the larger amount of calcium added into a petri dish will result with a faster hatching rate due to the extra nutrients. The independent variable of this lab is the concentrations of calcium, while the dependent variable is the brine shrimp eggs hatch rate. The constant is petri dish A that will have no calcium added. I plan on measuring this rate through observing the individual petri dishes every twelve hours under a magnifying glass and counting the number of eggs that hatch. The science of this lab can be traced back to the background...

...schmichael Brine Shrimp lab 2013 9/10/13 Introduction Artemia salina or (Brine Shrimp) belong to the Anthropoda phylum. Brine Shrimp are found in a variety of different habitats, ranging from temporary ponds to estuaries, lakes and rivers. A Brine Shrimp’s ability to inhabit various environments can be attributed to their tolerance of a range of salinities. Brine Shrimp have been found to survive in salinities from 0% to 15%. When hatching Brine Shrimp the highest number of eggs will hatch at a salinity of 7.5%. The ability to adapt to new environments gives Brine Shrimp a distinct advantage among their aquatic community, and allows them to successfully reproduce and survive within their environment. Materials and Methods In determining the optimal salinity for hatching brine shrimp eggs, seven samples were made with salinities ranging from 0%, 3.5%, 5%, 7.5%, 10%, 12.5%, and 15%. Four trials were performed for each of the seven samples. The room temperature and the water used were both at 72°F. The salt used to create the samples was supplied by Carolina Biological Supply Company. The seven ranging salinities were prepared in 100 mL samples. Seven masses of salt were measured on a scale (0g, 3.5g, 5g, 7.5g, 10g, 12.5g, and 15g) and were corresponded to a beaker filled with 100 mL of distilled water. For each sample, four trials were replicated by filling 30 mL plastic vials with 25 mL of solution. 2400 cysts (one...

...10-1. In condition two, denoted B, we created a 10-3 concentration of algae. During the collecting of the brine shrimp, they had yet to hatch and we found it profoundly difficulty to collect individual cysts. Due to this, we estimated the number of cysts to be placed in each jar. We first diluted the sample of cysts we were given and collected a loop full and added it to each jar. In between each inoculation, we shook the plate containing the cysts and water to evenly distribute them. To estimate the number of cysts added to each jar, we then collected a loop full and counted the number...

...Beren Robinson Field Study Tony Keulemans BIO/315 June 4, 2012 Olayinka Mintah Beren Robinson Field Study A field study by Beren Robinson on the threespine stickleback fish in the lake of coastal British Columbia showed some evidence of divergent natural selection. First, the study will be described. Next, the findings for the study and how the findings support evolution and natural selection. Finally, a proposed second study will be given. Study Description Beren Robinson reason for the field study was to determine if the constraints of two distinct environments affect the evolution of the stickleback species. He sampled a population where only a single species that tended to be the intermediate in morphology and habit to the limnetic or open-water and benthic or near shore water species. He then hypothesized that the individuals represented distinct phenotypes that were products of natural selection promoting divergence within the population. Robinson thought that trade-offs occurred when one task resulted in the cost of performance and fitness of other task. For example the limnetic species feeding on the plankton in open waters at the cost of being able to feed on sediments in shallow water while the benthic species feed on sediments in shallow waters at the cost of feeding on plankton in open waters. So Robinson’s decide to first variable to test was if the morphological differences between the two species were heritable or an expression of phenotypic plasticity...

...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...

...BIOPESTICIDAL EFFECT OF DIFFERENT KINDS OF CHILI PEPPER ON GOLDEN KUHOL (POMACEA CANALICULATA) A Research Proposal Presented to the faculty of Science Department In Partial Fulfilment of the Course Research II Jaira Belle G. Venturillo IV-Rutherford September 2013 BIOPESTICIDAL EFFECT OF DIFFERENT KINDS OF CHILI PEPPER ON GOLDEN KUHOL (POMACEA CANALICULATA) INTRODUCTION A who’s who of biopesticide is therefore of concern to us all. If we are going to live intimately with these chemicals formulating them within the plants and then eventually eating them, taking them into the very marrow of our bones, isn’t it like digging our own grave? On today’s status quo one of the major problems in the Philippines is about health, and one of the main cause of this is about what we eat, which as we can see chemical products are abundant in the Philippines. Rice is an everyday consumption of Filipino’s diet which is believed healthy for our body and abundant throughout the Philippines, but what if shortage of this production is experience because of pests invading towards Philippine rice fields. Believe it or not, this healthy is now considered insalubrious facing the fact that chemicals that are practiced towards the plants which serves as pesticide against kuhol will also harm our body, because farmers have no choice but to use chemical pesticide to eliminate these pests, is there? Before the introduction of chemical pesticides our native kuhol was a good source of...

...A Review of Literature Related to Oil Spill Dispersants 1997-2008 for Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) Anchorage, Alaska by Merv Fingas Spill Science Edmonton, Alberta PWSRCAC Contract Number - 955.08.03 Disclaimer: The opinions expressed in this PWSRCAC-commissioned report are not necessarily those of PWSRCAC September, 2008 ii Abstract This report is a review of the literature on oil spill dispersants published from 1997 to August, 2008. The report identifies and focusses on recent advances in dispersant effectiveness, toxicity, and biodegradation. Other topics such as application, use, behaviour and fate are also covered. The prime motivation for using dispersants is to reduce the impact of oil on shorelines, thus the 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...
