Echolocating bats article

Submitted by ryip on Fri, 03/31/2017 - 16:19

he article mentions that “water surfaces are special in that they represent the only extended, acoustically smooth surfaces in the natural environment”, which is an important factor in how bats are able to perceive aquatic surfaces. They hypothesized that “bats rely on the mirror-like echo reflection properties of smooth water surfaces in order to detect and recognize bodies of water” and that when a “bat flies over a water surface and the axis of its echolocation beam intersects with the surface at an acute angle, the main energy of the echolocation calls is reflected away from rather than back towards the bat, so it does not receive an echo ahead.” This would mean that whenever these bats encounter a smooth and horizontal surface with these acoustic mirror and echolocation properties they will perceive it to be water. 

Research Proposal Intro draft

Submitted by ryip on Fri, 03/31/2017 - 16:18

From a single patch of moss there could potentially be several thousand organisms found to be thriving within the plant. This research project will focus on the diversity and population density of the various organisms found within different species of moss found around the UMass Amherst campus. The data collected would help us determine the most abundant microorganism found in moss plants around campus.

           Mosses have been proven to be an important component in an ecosystem. Moss plants provide a good habitat for living organisms to thrive, as they have good water retention and provides insulation against rapid temperature and humidity changes. Moss plants have been found to serve as temporary bodies of water that can support aquatic as well as terrestrial fauna, which would make this plant one of the best sources for finding organisms.

           The main types of organisms we will focus on are aquatic moss-dwellers, which include nematodes, tardigrades and rotifers. These three invertebrates are the most dominant species found in moss plants, and will most likely be the species found in our mosses of interest.

The overall purpose of this Methods project is to prepare a thorough and descriptive manuscript with illustrates the process of research and documentation of a common subject, such as a patch of moss. This project demonstrates the importance of descriptive writing in order for scientific readers and researchers to replicate and perform identical experiments. In order to demonstrate this, a moss plant was required to be located, described and documented. Using visual documentation, such as close-up photos and geographical map images, a multi-panel scientific figure was formed as well. The project then tasked another colleague to replicate the location, description and documentation of the plant, allowing them to create their own multi-panel scientific figure that would allow them to form a similar multi-panel figure. The results indicated that with all replicate experiments there are errors and subtle differences that can affect or change the overall outcome of the initial experiment.

Animal Behavior Research Idea

Submitted by ryip on Fri, 03/10/2017 - 10:47

For my Animal Behavior lab we needed to come up with ideas of an experiment we can conduct on animal behavior. I chose to focus my proposal on observing and experimenting on squirrels. I came up the idea with observing the efficiency of squirrels collecting food when there is some sort of inference in the way, like humans or natural obstacles. The experiment would time and test how fast the squirrels would be able to collect the food, and to see if they will be able to learn from past trails or by observing other squirrels performing the same task. 

Photorespiration journal

Submitted by ryip on Fri, 03/10/2017 - 10:46

In my plant physiology class we were discussing the process of photorespiration, which is a process in plant metabolism that take place with CO2 levels are low in plants. I was initially fascinated to learn that a component reaction in photorespiration called oxygenation was considered a very wasteful process it works at a slower rate than other metabolic processes and it requires a much higher metabolic cost. It made me wonder why plants haven’t evolve this process to be more efficient but I realize that this process still essentially does it “job”, just at a much slower rate than ideal. Another interesting component of photorespiration is its usage of an enzyme of RuBisCO. I was shocked to find out that RuBisCO is one of most abundant enzyme in the world because it was an enzyme I had never heard about until we learned about it in lecture.

Image 10

 

  • Out of focus
  • Slightly different distances/zoom
  • Slightly different angles
  • Images aren’t cropped the same
  • Different time of day/weather conditions

 

The first set of images seem to be very out of focus, or the images were taken with a low-quality camera, while the second set of images is in focus and has a better camera quality. The two sets of images seem to have been taken a slightly different angles or used a slightly different zoom. The two sets of images also have a noticeable difference in the time of day and weather condition when the images were taken. Figure A in the first set was taken on a cloudier day, while Figure A in the second set was taken on a day with significantly less clouds. Figure B in the first set seems to have been taken when the sun was rising/setting based on the lighting of the trees in the background, while Figure B in the second set was taken on a less sunny day. Significantly more snow in the first set of images compared to the second set: In Figure A of the first set, there is noticeably more snow on the rooftop than on the rooftop seen in the replicate figure. Figure C of the first set also shows more snow on the pathway next to the tree, while the replicate figure shows that the snow on the pathway has melted a fair bit. Snow on tree trunk.

Pill Bugs Perfect Paragraph

Submitted by ryip on Fri, 02/24/2017 - 16:07

During one of my labs, we were observing and experiment the behavior of pill bugs.. The two pill bugs we were given reminded me of the white worm-like creature we were given to observe on the first day of BIO 312. The pill bugs seemed to behave and interact with the Petri dish environment the same way as the white worm did. The only noticeable differences between the two were the movements and appearances of the each creatures. In lab, we observed the pill bugs for several minutes at a time, jotting down details about their behavior in 30-second intervals. Eventually, we moved on to the experiment portion of the lab, in which we would choose different environments for the pill bugs to interact with. To do this, we taped two Petri dishes together while making an intersection between the two, which would allow the pill bugs to potentially move between Petri dishes. Using this unique Petri dish, we experimented on whether pill bugs prefer a wet or dry environment. We did this by wetting a circular piece of paper towel, which would be placed on one of the Petri dish, while we placed a dry circular piece on the other Petri dish. We then placed one pill bug on the wet side, while the other was placed on the dry side. We observed the pill bugs interaction with these environments for several minutes, noting whether they traveled to a different environment as well as when they would make the transition. The experiment was an interesting way to see what environment pill bugs preferred in a completely controlled setting, and it was also interesting to see if our initial predictions were correct.
