Introduction

The purpose of this lab was study animal locomotion in the Periplaneta americana (Palmetto Cockroach) and the Gromphadorhina portentosa (Madagascar Cockroach) across three different surfaces; smooth, American bark, and sandpaper. The Palmetto is known for its speed and ability to evade capture while the Madagascar stands out for its intimating hissing. Observing locomotion through three different gradients allowed us to the strengths and weakness’ in ability to maneuver between these two species.

Methods

One Palmetto and one Madagascar cockroach were used through each of the three surfaces. The placement of these roaches was parallel to that of a meter stick to ensure clarity of our video. Data was recorded through a high

Figtree Project

...3rd CPR Assignment The purpose of this assignment was to understand and construct phylogenetic trees about various species of trees. Both morphological and molecular phylogenetic trees were constructed. Morphological trees are based specifically on the external and physical characteristics of the organisms of focus while molecular trees are based on the actual DNA sequences of each organism involved. The outgroup for both of the phylogenetic trees constructed was Fagus grandifolia. This particular species of tree was selected to be the outgroup because it is an American Beech being compared to a group of oak trees. Outgroups serve as a basis for comparison for the rest of the organisms in the group since they share no similar characteristics between the rest of the organisms. In order to create a morphological phylogenetic tree for the trees in the assignment, the various characteristics of the leaves and acorns of the trees were examined at great length. These characteristics were categorized into specific groups that could be distinguished. These characteristics were arranged into a table that labeled and accounted for the specific features of the leaves and acorns of each specific species of tree. This information was obtained based on the observational opinion of the observer who was examining the leaves and acorns of each tree, and all this data was converted into a phylogenetic tree through the usage of the FigTree program. In order to create a molecular phylogenetic tree...

...Cockroaches are one of the oldest groups of insects, indicating how successful they have been in adapting to changes in their environments. One reason for this success may be related to diet--they are scavengers and will eat anything organic. They prefer food sources such as starches, sweets, grease and meat products, but other items may include cheese, beer, leather, glue, hair, starch in book bindings, flakes of dried skin or decaying organic matter (plant or animal). Cockroaches are attracted to warm, moist environments. They spend the daylight hours in dark, secluded sites under refrigerators, stoves, false bottoms in kitchen cabinets, in the backs of cabinets and in crevices between baseboards and floors or cabinets and walls. They may also be found behind pictures or within electronic equipment. A number of these openings will ultimately lead to voids in the stud walls. The insects leave these sites at night to forage for food and water. The presence of cockroaches during the day may indicate a large population. There are about 3,000 species of cockroaches in the world and about 50 occur in the United States. Of these 50 species, the three most common in the Northeast are the German cockroach, the American cockroach and the brownbanded cockroach. German Cockroach: Blattella germanica The German cockroach is 12 to 17 mm (1/2 to 5/8 inch) long, tan to light brown, and has two dark brown stripes on the body region (pronotal shield) just behind the head. Females will produce...
