  • Anxiety And Behavior Analysis

    Anxiety is a behavioral response triggered by: stress, fear of outcomes, or apprehension of an imminent event. Symptoms of this response usually include a feeling of nervousness, unease, or worry-some tendencies. Due to the key component of anxiety being stress, there is a state of mental strain among the individuals or organisms enduring this response. In years past, scientists have observed and concluded findings of anxiety-like behaviors in humans and different vertebrae species. For the first time in history, scientists from the University of Bordeaux have found traces of this same behavior in invertebrates. Science Daily has published an article on the twentieth of June in 2014 that is a representation of the actual study. Although it…

  • Stream Quality Data Analysis At Tulip Spring, New Jersey

    Stream Quality Data Analysis Abstract A Stream Quality Data was collected at Tulip Spring, New Jersey through a macroinvertebrate collection that had been used to identify the quality in which this freshwater animals were living. Collection and preservation of such invertebrates help in the determination of its water quality and capacity to tolerate pollution. Also a biotic index calculation was applied in order for the result of our findings giving a polluted water quality. The streams were…

  • Invertebrate Diversity

    This study examined the effects of physical factors on diversity in freshwater environments by observing invertebrate diversity in riffles and pools in a freshwater stream. It was hypothesized that differences in invertebrate diversity between riffles and pools would be due to physical factors in the environment. To test this hypothesis, invertebrates were collected from each environment and classified by their taxa, and Shannon-Simpson indices were produced from these data to analyze the…

  • Diversity In Arthropod Communities

    Introduction The diversity of arthropods extends beyond the location factor alone as multiple influences such as humidity levels, atmospheric content and other environmental conditions contribute to their widespread assortment. Gaps in diversity indices do not only occur amongst insect populations residing at regionally distinct locations as these influences are also reflected in arthropod communities over small distances. Climatic conditions often lead to insect migrations and extinctions which…

  • Importance Of Marine Invertebrates

    Microbial associations with marine invertebrates Marine bacteria can have a large impact on other marine organisms throughout their lifecycle. Marine invertebrates may comprise more than 30% of all animal species and are commonly associated with distinct microbial communities (Otero-Gonzáles et al., 2010). Bacteria, archaea and single-celled eukaryotes may act as larval settlement cues, symbionts or pathogens to a range of marine invertebrate phyla. Bacteria quickly colonize available…

  • Charles Darwin's Accomplishments

    Charles Darwin was a great scientist. He was one of the first to propose the theory of evolution.1 He also traveled around the world and learned about types of invertebrates.2 He has also studied medicine and written many books including The Origin of Species.2 These are just a few things about Charles Darwin that he has done in his life Charles Darwin has done a lot for the scientific world. Darwin came from a long line of scientists including his father and grandfather.2 When Darwin was only…

  • Prehistoric California During The Prehistoric Period

    PREHISTORIC CALIFORNIA During the prehistoric periods, California was covered by a warm shallow sea. This sea was mostly inhabited by various marine invertebrates, for instance, corals and brachiopods. Later on especially during the perminian periods, California began to exhibit a variety of habitats. This was characterized by both deep and shallow marine deposits. Swamps and estuaries would also be found in some parts of the land. California could also be described as a region of geologic…

  • Daphnia Pesticide

    In future study, a more commonly used pesticide could be tested on these small water invertebrates because if the pesticide we used in our experiment have the abilities to disrupt the normal activities of Daphnia, then more question can be raised about its impact on human. From our sample size, at least 30 daphnia died within half an hour after being exposed to Atrazine and 24 were immobile with their pigment changing from normal to a whiter color as they die off. Leromina et al. (2014) observed…

  • Mud Flats Habitat

    Mud flats are a vital type of marine habitat that provide several different functions for various marine invertebrates. They provide both permanent and temporary homes to small invertebrates including several species of worms, crabs, snails, and other benthic fauna. These organisms are responsible for the breakdown of organic materials often deposited here, as well as filling the role of prey for many predators that hunt in the shallow waters (Dyer et al., 2000). Mud flats are most often…
