For example a bird’s beak may be longer or shorter depending on how they can attain food in the location they reside. Natural selection has different branches to it; the one studied in this lab is called directional selection. Directional selection is when an extreme phenotype is favoured over other physical alleles (Reece). The directional selection that may be present within this study is if gall size determines if the larvae is dead or alive. Gall flies lay their eggs at the tip of goldenrod shoots which hatches into the larva during the summer. The larva bored into the plants stem and begins forming a gall. The galls reach their full size at the end of the summer while the larva matures throughout the year. This is when predators start to attack the goldenrod and feed on the fly larvae within the gall. These predators include parasitoid wasps (Eurytoma gigantea and E. obtusiventris), the beetle (Mordellistena unicolor) and birds specifically the downy woodpecker and black-capped chickadee. The parasitoid wasps attack during the summer months. The female wasp uses her ovipositor to lay her eggs within a hole in the gall originally made by the fly larvae. The wasp larvae then feed on the fly larvae and continue to reside in the gall. If the gall is too thick the ovipositor will not be able to make it into the gall to lay eggs. The…

    Even when the beauty surrounded me, The mosquitos would not forget about the scent, I then looked like a huge walking mosquito bite. The mosquitos gave me what felt like millions of bites even though there were probably at least 50. When the mosquito attached to my arm it felt like a paint brush swiping against my arm.

    There are several different kinds of arthropods that feed off of and find nutrients from blood. These kinds of arthropods are also called “hematophagous,” or “bed bugs.” In this experiment, the researchers attempted to distinguish which chemicals would most effectively initiate and persuade feeding in different parts of a bed bug’s life. Various feeding stimulants, such as ATP, ADP, and AMP were used in a feeding system. Of these stimulants, it was found that the most effective chemical in…
