During my travels in the continent of South America in the diverse country of Brazil I encounter an unusual creature, one I have never seen before and was intrigued. This organism was located in the tropical rainforest. Where precipitation exceeds 70 inches annually. This biome contains approximately 50 % of the world species in simply about 11% of its terrestrial vegetation cover so I was really excited to have found it here. This biome experiences warm seasonally invariant temperatures. This habitat contains broad leveled evergreens and deciduous trees with sunlight being a key resource that contributes to the vegetation structure (Cain et al. 2014). 

The Tasmanian Devil is an iconic, and charismatic species that lives on the Island of Tasmania off the coast of Australia. Reports started 1996 of Tasmanian Devils with large facial and neck tumors. The cancer is transmitted through an infected individual by biting a healthy individual. Due to the Tasmanian Devil’s tendency to fight, and bite each other over territory, food and sex the tumors are passed fairly quickly through populations. The tumors begin to proliferate and can prevent the Tasmanian Devil from breathing, and eating; however, it may take time for the tumors to get large enough to do kill the infected individual giving the cancer plenty of time to get passed on. The tumors are killing many Tasmanian Devils and certain populations throughout Tasmania have been reduced more than 90% in the last 20 years and is now considered endangered. 

There are many issues regarding food safety and the current methods and infrastructure in place to track food products through the journey from farm to store shelf are not sufficient. There is no standardized system for tracking food and many processors handle it differently. When there are issues with contamination, lengthy and resource intensive traceback investigations must occur. Some distributors keep records in closed databases or on paper meaning they are not readily accessible or publicly available. Frank Yiannas, Walmart VP of food safety, mentioned in an interview that after giving staff a randomly selected package of mangoes, it required almost a full seven days to trace them back to the source.  In seven days, hundreds of thousands of people can be significantly harmed by a contaminated product.

Arthropod emergence could also be mainly driven by temperature. A change in temperature by only a few degrees will affect whether arthropods will be present or absent (Hannson et al. 2014). This information can be used to take into consideration the variation in temperature within both Morrill buildings and within the different floors. If the weather is hotter, there will be more insects or organisms present. If the weather is colder, there will be less. Therefore, if the temperature inside a certain part of the building is hotter, there will be more organisms present. If the temperature is colder, there will be less.  

Many of these experiments have a similar design. They have a way of measuring diversity in the species; when the organism is a type of insect the method to measure is usually setting traps and counting the number of different species.

The different insect species in relation to their indication of different environmental factors has been studied and documented thoroughly, but the diversity of these insects has not been tested in this area. This experiment uses a well-tested method to find biodiversity to discover more about the area in which we live.    

Photosynthesis is an essential reaction in order to sustain life. The products of the essential reaction include oxygen and glucose. Besides the obvious benefits in the production of glucose and oxygen these products prove to have many important functions within the cell. The glucose produced from the reaction is converted into storable starch. This starch can then enter the plasma membrane where it interacts with the cellulose synthesis complex. The product of this interaction is cellulose, the most prominent and strongest component of the cell wall. Considering that cellulose is the most prominent component of the cell wall and is present in the majority of plants in the world many scientists consider it one of the most abundant organic compound on earth. Cellulose is also a large source of fiber in the average humans diet.

Purpose of this lab is to dehydrate cyclohexanol and synthesizing cyclohexene by taking all that we’ve done so far. These processes include taking the melting points, boiling points, molecular weight densities, and figuring out what the hazardous properties are. By separating and purifying the substance using combination of extraction, distillation, crystallization, chromatography, and more the lab is complete. There are many processes that we learned so far in the lab shown right above, and honestly it was all pretty simple. There are step by step display on what we have to do on the organic chemistry 269 website. Lab reports are fairly simple as well, it just takes some time to complete them. My favorite one is crystallization because different crystals are formed whether it be different color, different weight, and more factors.

For the chemotaxis portion of the motility and chemotaxis lab, I hypothesized that the Serratia marcescens will move towards the nutrient source rather than the Enterococcus faecalis. I expect these results to occur because Serratia marcescens is a known motile organism and reacts in the presence of nutrients and therefore will be chemotactic, this same attraction will occur with the glycerol yeast extract (GYE). I began my experiment by collecting and labeling two petri dishes, I then added molten GYE to the label portions of my plates and let it solidify. After I added molten water agar into the halves of the petri dishes, again letting it solidify. I then put two pieces of filter paper on the plates creating a bridge for the bacteria to move throughout, I then inoculated the organism on each strip of paper at opposite points from each other, creating a diagonal cross.

Avian species, particularly those in the African and Asian regions,  have developed a wide array of breeding techniques that have been driven by one factor, successful inheritance of their genes. Two particular forms of breeding, cooperative and brood parasitism, have been observed to closely overlap, implying correlation.  Cooperative breeding, where several non-paternal individuals assist with care are frequently targeted by brood parasites, who trick these species into caring for their young as well. This study serves to investigate whether the evolutionary basis of these two forms of breeding are a coincidence secondary to similar environments or the site of an evolutionary arms race between these two conflicting breeding styles that is driven by brood parasitism.
