    Daphnia pulex are tiny aquatic crustaceans which have a translucent body which allows us to observe their internal organs in thorough detail. Daphnia is alleged to be a substitute of a human being in this experiment to examine the effects of chemicals on a heart of beings or other species for that matter . This will be measured by the heart rate as the heart rate is the contraction in one complete cardiac cycle. Furthermore Daphnia pulex is the most common species of water flea, an organism which can be found in almost every permanent, eutrophic water body. Generally Daphnia are freshwater organisms.…

    In this lab, we participated in many tasks that described the water quality of the Chippewa River. Some of us collected data for three parameters that describe the water quality: macro invertebrates, habitat quality, and water chemistry. Under water chemistry, we collected the waters dissolved oxygen, nitrogen and phosphorus, and pH levels. The group with habitat quality assessed the waters velocity, temperature, water depth, discharge, riparian vegetation, and substrates. My group studied the micro invertebrates that lived in the Chippewa River.…

    The Pacific leaping blenny is a small fish found on the tropical island of Guam. Its scientific name is Alticus arnoldorum and it has made one of the most tremendous ecological transitions over time. The Pacific leaping blenny effectively established its population on land through an evolved variety of adaptations, such as: the ability to move efficiently on land and being able to perform respiration through its skin while still relying on its gills. The fish are limited to the “splash zones” of the intertidal areas around the island of Guam, so that they can avoid desiccation. The fish, however, seemed to be terrestrial and would almost never return to the water.…

    Native species are species that have evolved to in a particular region over a long period of time, and have adapted to live in that region’s climate and habitat. These species live in this region with all the other species to form an ecosystem. Non native species on the other hand, are species that are introduced to an area they're not used to by humans, either by accident, or intentionally (getthegreen). Invasive species are a type of non native species, that are very likely to cause harm to the ecosystem (NOAA). They destroy the habitat of other species, and eventually kill plants, and/or other species.…

    Invasive species are easily comparable to the explorers of the old days. Explorers could be helpful by introducing new supplies, like horses, during the big Columbian Exchange. Explorers could also be largely negative, bringing disease and slavery into the nations they conquered. Explorers sometimes just set up trade relations and left well enough alone. Much like these explorers, invasive species have the propensity to help, hurt, or assimilate into their new surroundings.…

Here in Minnesota, There are 22 species of amphibians and 31 species of reptiles, ranging from the fast moving salamanders to the slow and nimble turtles. I got the opportunity to further research the Blanchard’s cricket frog, in hopes of understanding their feeding behavior, reproductive patterns, seasonal movements, and communication interspecifically as well as intraspecifically.

    Writing Assignment #1 Lasiognathus dinema There are a couple misconceptions you might have about evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living organisms is to be born, survive, mate, and die, it is impossible for an organism to live through several generations.…
