Invertebrate Essays

Observations: During the dissection, there might have been a few things observed. Two main observations that may have been noted was the change of colour and ring like segments. It may have been noted that the back and front side of the earthworm consists of two different colours. The back side of the earthworm is referred to as the dorsal side and the front side of the earthworm is referred to as the ventral side. A distinct observation is the fact that the ventral surface of the earthworm is a

Cephalopoda Introduction: Invertebrate animals which belong to mollusks which means “head foot” and characterized by large head and modified feet. This group includes octopuses, squid, cuttlefish and nautiluses. Members of cephalopods are characterized by their ability to quick change their color as well as changing the texture and shape of their bodies as a means of camouflage. Today there are about 800 living marine species of cephalopods which are found in all of the world’s oceans, from the

vertebrates and invertebrates. Vertebrate invasive species consist of the brown tree snake (Boiga irregularis), Burmese python (Python molurus bivittatus), common starling (Sturnus Vulgaris), and the wild boar (Sus scrofa). The brown tree snake is a native of Australia, Indonesia, Papua New Guinea and the Solman Islands, researchers seem to believe the brown tree snake hitchhiked to Guam on military aircraft in the late 1940s early 1950s (Lowe S., Browne M., 2000). Examples of invertebrate invasive species

The question asked is: “What is the water quality of the U-High creek based on invertebrates found in the water?” There are many ways to measure water quality, primarily through pH, nitrogen, phosphorous, and dissolved oxygen. pH levels are the levels of acidity or alkaline found in the water. Low pH levels (under 7.0) mean that the water is too acidic. High pH levels (over 7.0) mean greater alkaline level. A pH range of 6.5 - 8.5 is a safe range for aquatic life. Nitrogen and phosphorus are elements

Diversity in the Charles River (Anything in parentheses is optional unless you are planning to do a follow up lab on the water itself) How does location affect macro invertebrate diversity in the Charles River? Hypothesis: I believe that species diversity will not change as we move closer to the ocean. Introduction: Biodiversity can be seen as “the variety of life” (https://www.nwf.org/Wildlife/Wildlife-Conservation/Biodiversity.aspx). Biodiversity can be observed on a large scale, such as global

Troy Daum November 8th, 2017 AEPS 110 The Moral Efficacy of Animal Experimentation on Invertebrates Animal experimentation is a practice that spans thousands of years and has been crucial to the advancement of scientific knowledge in a broad range of disciplines from health and medicine to genetics. The earliest writings of scientific inquiry through this means traces back to the Ancient Greeks, which describe dissections of farm animals as an “experimental method of testing surgical procedures

adulthood experience with nature. Jane Goodall had always had a passion for animals including insects. She watches wild chimpanzees make tools to get and dig out termites from their holes. This relates to the argument because she studies how these invertebrates are getting extinct due to the loss of habitats and how people use chemical pesticides. Due to them focusing only on

the invertebrates can be used to measure water quality, and through the impact of water quality on stream ecosystems. For the measures of water quality the dissolved oxygen is the oxygen that is in the water. The amount of dissolved oxygen in the water must be in high concentrations. The pH of a substance is the measure of hydrogen ions in that substance. Healthy creek pH levels should be between 6.5-8.5. There should be a low concentration of phosphorus and nitrogen in the

The increasing temperature in the Columbia and Snake River Basin will provide less of a habitat range for the cold water species, sockeye salmon. The reason being that if the salmon were to attempt to inhabit these warmer waters the individuals that are unable to physiologically acclimate to these new temperature conditions will die; thus decreasing the relative abundance of the sockeye salmon’s population in these areas. The decrease in the amount of sockeye salmon will in-turn affect the communities

separated e.g. Paramecium. The fertilization may be internal or external. It depends on organism and its environment in which that animal live. In external fertilization many invertebrates simply release their gametes into water in which they live and allow them to fertilize (e.g. sponges and corals), while in some other invertebrates utilize internal fertilization to transfer sperm

many have never heard of cold water species like the Shanny or Tompot Blenny. Since you only have to take care of the fish in this type of saltwater aquarium, it is generally the easiest saltwater tank to maintain. 2. Invertebrate Only Aquarium Obviously, you will find invertebrates in this type of saltwater tank. That includes hermit crabs, prawn, shrimp, and sometimes sea cucumbers or

Since hogs are omnivores, they can have a variety of effects on many different animals from amphibians to mammals. Pigs eat a variety of items, including fruits, roots, mushrooms, and invertebrates, depending on the season. The major foods in spring are herbage, roots, invertebrates, and vertebrates. Fruit, invertebrates, and herbage are most common in fall and winter diets. Herbage eaten by feral pigs

I am interested in a career in conservation biology and ecology of aquatic biomes, so I am applying for a Master of Science in Biology. Growing up in Puerto Rico, I was fortunate to have a childhood within a tropical oasis, where the Caribbean Sea meets the Atlantic Ocean. Where the trade winds developing in the Saharan dessert go passed the Atlantic Ocean and through the mountain range crossing the island horizontally, rain shadowing the southwestern portion of the islands dry forest. This climatic

event comes, Spiker and Sponge task James to pick up rubbish that the guests drop. Upon doing so, he sees a tunnel and explores it, only to find the center of the peach inhabited by a gang of human-sized invertebrates. As James proceeds to climb into the center, the Centipede, one of the invertebrates, severs the stem of the peach. As a consequence (or reward, depending on the how one looks at the situation), the peach rolls down the hill, crushing and killing the two aunts in the process. The peach

octopus even though they are super smart. Octopi are so intelligent in many ways, one of which being that they can figure out how to get out of any space bigger than their tentacle. "They are one of the smartest ocean animals and the smartest invertebrates" says Tracy Jackeline from the Smithsonian newspaper. Biologist say that they are as smart as the average 2 year old, which goes a long way with the animal kingdom. This being the case they can easily outsmart their prey as well as their intensley

The taxon I identified, as predators were the horn coral, any other coral from the Cnidarians, and the cephalopods. I calculated the amount of predators in each level by dividing the number of taxon in that invertebrate by the overall number of taxon within that level. The results were: bottom level 0.2, middle level 0.6, and top level 4.8. These results show almost a 7-fold increase between middle level and the upper level. This much of an increase proves my

It likes to eat insects and bugs. Another animal affected by the bushfires is the Smokey mouse. It’s habitat of ridge tops, open forests and sub-alpine regions of up to 1800 metres was severely burnt. It eats seeds, fruits, flowers and some invertebrates. It also likes to eat grass trees or Xanthorrhoea spp. Another fauna that was around before the bushfires was the bush-tailed rock-wallaby or Petrogale penicillate. Its habitat of rocky escarpments, outcrops, cliffs, caves and ledges faced near

“A righteous man regardeth the life of his beast: but the tender mercies of the wicked are cruel” (King James Version, Prov. 12.10). In order to fully regard the life of God’s beasts, we must preserve/facilitate their population so others can look and marvel at God’s creation. Information shows that seahorse populations are commonly vulnerable to heavy exploitation due to traditional Chinese medicine (TCM), aquarium trade, and destruction of natural habitats (Allee). The IUCN red list of threatened

dramatic burst of Evolutionary changes in life on Earth, known as the "Cambrian Explosion. Plant and Animal Life • In the Cambrian period life was in the oceans and some of variety of microscopic plants were in the oceans. Many Early Cambrian invertebrates are known only from "small Shelly fossils". • There were a variety of microscopic marine plants like the Margarita. • The most important animal group of the Cambrian were the trilobites. • The period marked a fast change in the variety and composition

This laboratory experiment involving invertebrates is conducted to enable students to investigate Daphnia magna’s responses to external stimuli, therefore developing a better understanding and knowledge of homeostasis that occurs in organisms and the reaction and behavior exhibited by the daphnia magna when varying conditions are exposed to the organism compared to its natural environment conditions (Carter-Edwards et al, 2011). In order to understand the experiment, a foundation of information about
