Millipedes Lab Report

Our null hypothesis is that if a pathway is drawn with anything other than ink, the termite will not be attracted to it and will not follow the path drawn.

A. Eucalyptus leaves are very important for their survival considering that is mostly all they eat.

Desert’s impact humans by Something called Desertification, Desertification is when fertile land becomes Desert. “ ... Desertification directly affects 1.2 billion people” (Doc 3). This shows that Desert’s affect people badly. Desert’s are dangerous as they can kill plants and animals. “ But even small changes in temperature or precipitation could drastically impact plants and animals living in the Desert.” (Internet). This shows that small changes in the Desert can affect a lot of living things. To recapitulate, Desert’s can be discussed by their impacts on humans.

The soil commonly found is alkaline which allows the desert plants to grow and gain nutrients through the roots in the ground. the temperature allows for Predators to be able to hunt for longer stretches of time in cooler temperatures and often rest in the shade in preparation of hunting in the warmer temperatures. the sand dunes help to Prevent soil erosion by storing sand that replaces the eroded sand below with more sand so the total amount of sand in an area does not decrease.

Figure 1. A Comparison of a CAP Recording of an Earthworm to an Intercellular Recording. The “taller” graph is a depiction of a microelectrode recording of an action potential inside a neuron. The highlighted graph is a depiction of an extracellular recording suction electrode on a giant earthworm. The dotted line represents the minimum voltage needed to depolarize an action potential. The results are obtained from a PowerLab Data Acquisition Unit and a LabChart computerized software. The data are recorded in units of milliseconds and millivolts.

There 5 classes of Arthropods. There are the Myriapods, Trilobites, Chelicerates, Crustaceans, and Insects. The Myriapods are many footed and have one to two pairs of appendages per body segment. They are the centipedes and millipedes. Trilobites are extinct and we only have their fossils. Chelicerates are the Arachnids and anything with eight legs. Crustaceans are the crabs and anything with ten or more legs. The insects are the ones with 3 pairs of legs and body regions. They all have a segmented body plan, exoskeleton composed of chitin, bilateral symmetry, and paired jointed appendages. In our lab we were trying to identify and label the internal and external anatomy of a grasshopper from the class insecta.

Humans influence the desert in many ways. We can cause more desertification or we change some of the land into farmable land. Humans have mines out in the desert also that can disturb certain organisms. Also we divert water for crops and intersect the desert with roads or

Two experimental errors that occurred during this experimentation were that the mealworms would find their way to move under the paper towels and the paper towels were not cut down to a size where there is a clear passageway in between the petri dishes. The paper towels were cut roughly to fit in each petri dishes, but it was a poor choice to make in hindsight. We had to constantly pick up the mealworms that had crawled under the paper towels with tweezers and that could’ve aleterd the final results. What could have also altered the final results was the fact that the paper towels were not cut in a specific way to allow any easy passageway for the mealworms to pass

Earthworms “are not really supposed to be in some of these areas,” says Tara Bal, a forest health scientist at Michigan Technological University in Houghton. In the northern forest soil is naturally stratified and nutrients and can only be found in

The study aimed to decrease the density in the designated plots to determine if this change would cause an increase in the growth of other species. This result would contribute to the theory of interspecific competition present in this community. Others have found that competition may be less important than other interactions such as predation amongst insects. This study found that after the removal of E. obscurus there was no increase in the density of the other insect species nor was there an increase in their size. The other species did not show the expected increases that were thought to occur if the competition was removed. There is not enough information to conclude the role of competition in this particular darkling beetle

Chatterjee (1972) and Eggleton (2007), stated that among the beneficial aspect of termite is decomposition, they cause to dead wood in the forest, which would have pile up and suffocate young plants, and through the decomposition they increase mineral component of the soil, by introducing into the soil mineral nutrients of the dead woods, also the burrowing they made in the soil increase water absorbent of the

Centipede could be any color and he has a long body, but mainly a shell with on it. Kinda looks like scales going down it's spine which make it a take on any other insect in a fight. to other insects that try to eat him or mammals, Which they do carry poison. which can kill an animal or person within 3 minutes, they live in the hot spots of South America. They feed on grasshoppers most of the time to eat, which is there only thing they can get a hold of it Their size can range from a few millimetres in the smaller to about 30 cm (12 in) in the largest Centipedes can be found in a wide variety of environments in South America, mainly in the jungle they stay. Under rocks to control

Throughout this world we call Earth, there aren’t many regions or continents’ that we humans call home that don’t have a desert biome, they existence on almost every continent. According to the Conserve Energy Future or CEF, “Deserts cover about twenty percent of our earth”, (Rinkesh,n.d). When the word “Desert” comes to mind you think of a hot, and lifeless wasteland that takes. However, I believe the stereotypical thought of Deserts being godless wastelands are wrong. I believe it is actually just a functioning, flushing environment just as any other.

By creating set indicators for deserts the spread of desertification can be gauged. Climate (Anderson,2001) is one of the larger
