Arthropod

Head The lady beetles head houses the eyes, mouth and antennae. Antennae The antennae works as the lady beetles sensor organ, the function is to aid the eyes for locations, tasting and smelling predators and prey. Eyes The lady beetle has two simple structured eyes which is why they rely so heavily on their antennas. Mouth The lady beetles mouth is made for chewing small insects during the larvae and adult stages. Abdomen The abdomen houses all the lady beetles internal organs, digestive…

Background & Objectives: Arthropods have neurogenic hearts, which have pacemakers as part of the nervous system found outside the heart. Vertebrates and molluscs have myogenic hearts, where the pacemaker is composed of specialized cardiac muscle within the heart. Daphnia is unique as it is a cladoceran crustacean reported to have a myogenic heart. To test this, use drugs known to change heart rate in myogenic hearts and observe if they have the same influence on Daphnia. Methods: Used a…

Arthropods are made up mostly of crustacean about 50,000 known and divided into groups; Branchiopods, Maxillopods, Malacostraca and Ostracods. The Malacostraca is divided into five different groups, decapods, stomatopods, euphausiids, amphipod and isopods. Decapods include crabs, lobster and shrimp it’s the largest species. Decapod means ten to five pairs of legs most first pair are modified as large claws, called chelipeds. Most decapods hatch as a zoea but on some occasion shrimp can hatch a…

In just the past one hundred years, the world has gone from new weaponry for the world wars such as tanks and other firearms. To nowadays, having robots replace human jobs and other machines replace such human ingenuity. With the increase in human reliance on technology, we have been using robotics which is a branch of engineering and science, to further our efficiency on certain tasks such as the manufacturing of goods. However while these robots are already influencing the manufacturing world…

Spotted fever group rickettsioses present a threat to human health worldwide. These bacteria are the cause of potentially fatal febrile illnesses in humans. They are transmitted by arthropod vectors such as ticks, mites, fleas and lice, which are associated with vertebrate host animals including rodents and companion animals. Background Rickettsia are obligate intracellular bacteria that are widely distributed throughout the world, causing both emerging and re-emerging infectious diseases…

“Scale-dependent habitat use of Acadian Flycatcher (Empidonax virescens) in central Ohio” by Marja H. Bakermans and Amanda D. Rodewald, published in 2006, examines the selection of habitat across three spatial scales and the effects of understory arthropod biomass, vegetation structure and breeding productivity. As human populations grow and urban development increases desirable habitat for many habitat-specific species decreases resulting in population declines. It is important to understand…

the food web (Chen & Wise 1999; Scherber et al. 2010). Garlic mustard can reduce mycorrhizal fungal abundances (both ecto- and arbuscular) via allelopathy, which is an important resource for springtails and fungivorous mites (Chen et al. 1996). Arthropod predators such as spiders, centipedes, and predatory mites can all consume fungivores for prey in the soil food web (Chen & Wise 1999; Koehler 1999). Therefore I predict: (1) garlic mustard invasion will have a negative effect on soil fungivore…

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…

There is a long list of natural and diverse enemies of ticks. Certain microbes, some mammals, several types of generalist arthropod predators, and even certain types of birds make up the majority of the list. Oxpeckers are one type of bird known for eating ticks. There has been indications they also cause damage to the host of the tick they are eating. Guinea hens, chickens and other ground feeding birds are also known to feast on ticks. Mammals groom and birds preen ticks and various other…

First, both the lecture and the passage talk about a theory of considering these animals as free-swimming predators. The reading claims that as similar as other primitive arthropods these small organisms were swimmers and preyed on a great deal of smaller organisms. In contrast, the professor rejects this claim owing to lacking the accurate visual ability. Some of them were completely blind and if they were able to chase preys…
