Invertebrate

the identification of species within a family as diverse as ground beetles (Choate, 2001). Ground beetles are one of the most diverse insect families in the word. They occur in apparently all terrestrial habitats and represent a major part of the invertebrate predator guild of the soil fauna, e.g. in forests, maquis and agrocoenoses (Arndt et al., 2011). Ground beetles are often chosen for study because they are abundant in most terrestrial habitats, diverse, taxonomically well known, serve as…

Evolution appears directional if we view the fossil record’s progress from simple unicellular creatures to multicellular ones, then invertebrates, dinosaurs, mammals and humans. This is supported by certain biologist’s who argue evolution favours the directional development of complex life . However, life is not a straightforward progression towards complexity. Natural selection can’t explain revolutionary change because while species produce evolutionary trends through their adaptive…

Summary Model Bifenthrin Concentration Prediction The prevalence of bifenthrin in urban Sacramento waters is most likely explained by their wide availability in for the control of ants. Although application amounts reported by professional applicators are not 100 percent correct and that of homeowners are not reported, data from the DPR PUR database indicates that bifenthrin is heavily applied by applicators in urban Sacramento. Additionally, these pyrethroids have a longer half-life than some…

Did you know that tapeworms are one of the first recognized parasitic worms? Also did you know that people intentionally sell tapeworms for weight loss, although it’s illegal? Those are just some fun facts leading into many of the characteristics that these parasites give have. There are very many cause and effect reactions that tapeworms give off. A tapeworm is a long, flat worm that attaches itself to your cattle’s intestines. A tapeworm body consists of multiple parts, or segments, with…

Today in America we have many exotic species that are introduced into our environment. Some of these species have been introduced on purpose and others by mistake. Other species are introduced into our ecosystem to help control a pest and others are introduced because they make good game to hunt or fish. Species that are considered to be an invasive species are labeled that because they have potential to harm and can spread aggressively. Invasive species can come around in a multitude of…

Robins are a beautiful bird and you can see them in the springtime. I wanted to write this because I have a robin’s nest in my backyard. I also like how gentle robins look. The American Robin’s size is about 9 to 11 inches long, a wingspan of about 14 to about 16 in long, and weight is 2 ⅓ to 3 ounces. The Robins communicate by usually singing to each other and other forms of communication. The bird can fly very fast at 20 to 36 miles per hour. They fly faster when they are migrating then flying…

The three-spined stickleback (Gasterosteus aculeatus) is a species of fish that exhibits a wide range of morphological variation within its subspecies, which typically fit into two categories, anadromous (spawn in freshwater, migrate from saltwater) and freshwater varieties. Saltwater marine varieties of the fish typically have two dorsal spines, along with a pelvic spine. These spines, as studies have shown, act as a defense mechanism against soft-mouthed predators, by increasing the diameter…

No one has influenced our knowledge of life on Earth as much as the English naturalist Charles Darwin 1809-1882. His theory of evolution by natural selection, now the unifying theory of the life sciences, explained where all of the astonishingly diverse kinds of living things came from and how they became exquisitely adapted to their particular environments. His theory reconciled a host of diverse kinds of evidence such as the progressive fossil record, geographical distribution of species,…

Species Name What is their common and their Genus species name? The common name of the Octopus Cyanea, also known as the Blue Octopus, is “Octopodidae”. The Genus species name is “Smoothskin Octopus”. Characteristics Describe the characteristics of your animal. The Octopus Cyanea is a marvelous creature. Their color varies, but they are usually a dark color, such as gray or brown. Even though they have a solid color, they have the ability to rapidly change their skin texture and color. The…

There are two major trophic cascades that scientist use. One is called bottom-up and the other is top-down. The controller of top-down would be the top predator or the apex predator (Wallach and O’Neill, 2009). The apex predator can also be known as the keystone species in that ecosystem. Top-down control is when the apex predator regulates the structure and population of the ecosystem (Wallach and O’Neill, 2009). The apex predators will prey on the consumers, which keeps the consumers…
