Extract of sample "Arthropods"

Download file to see previous pages Among the arthropods, insects portray the highest degree of species diversity (Lecointre & Guyanden 67). In this discussion, we will focus on the reasons why insects are the most diverse. This paper will also focus on the limitations of these diverse species.
Elipura is made up of collembola and Protura. The diplura is closely related to the insecta class. However, research indicates that crustaceans closely resemble insects than the entognatha class. Further research indicates that the collembolla have a different origin from the insects.
The first evidence of Hexapods dates back to the Devonian period (Approximately 390 years ago). During this time, the insects are said to have been wingless. However, the preservation of the fossils was poor due to their exoskeleton, which is made of chitin. The evolution of the wings was an adaptation to allow them to survive the harsh conditions of the terrain. Insect fossils believed to have been from the Devonian period have been described. The oldest is a precursor of Rhyniella Praecusor found in Scotland. Primitive rooted plants of the time were localised in moist areas, and hence created soil for early arthropods such as myriapods (Grimaldi & Engel 66). Today, majority of the insects are terrestrial with a few in the marine habitat.
The figures described in the previous slide are only representative of the species that have been documented. Forecasting shows that there could be many more species of insects living in non accessible areas that have not been scientifically described. To be recognized, insect species have to be described scientifically. This involves publishing of their description in the specialist journals. This is followed by thorough research. The purpose of this is to describe the insect, as well as classify it depending on it features.
New species are recognised after formal descriptions. In Borneo, for the decade 1994-2004, 361 new species were found. 260 ...Download file to see next pagesRead More

Taxonomy

...? Taxonomy                   Among the nine phyla of the animal kingdom, Phylum Porifera and Phylum Cnidaria lack organ systems. Moreover, they lack cephalization, as only six phyla show it – Mollusca, Arthropoda, Chordata, and the three worm phyla. It is also interesting to note that only the members of the Phylum Cnidaria do not possess all three germ layers. When it comes to the number of species, no phyla can outnumber the arthropods, which include arachnids, crustaceans, insects and other subphyla. As to the development of the fish, the armored fishes developed first, then followed by the jawless fishes, the cartilaginous and finally the bony fish. Lastly, when it comes to the development of their young, mammals can...

Any organism or group of organisms

...of appendages. The first is the chelicerae, or mouthparts on which you find their fangs. These are used for feeding and defense functions, grabbing or poisoning prey. The second pair is called the pedipalps. They have mainly three functions: for feeding, movement and reproducing. Another feature of arachnids that makes distinguishing insects from them easy are the fact that arachnids do not possess any antennae or wings. All arachnids also contain exoskeletons just as all arthropods. Arachnids are typically meat-eating organisms. They feed on pre-digested remains of insects and other little organisms such as flies, bees, ants, crickets, wasps, grasshoppers, beetles, bugs and even others of their kind. Only two kinds,...

Phylogeny Research Paper

...animals. Mostly, this view has given way to one that places arthropods and onychophorans in a clade of moulting animals. Discuss the evidence for discarding the former view and switching to the newer one. Your answer should include a cladogram of moulting animals with supporting evidence In the past, the Onychophora (velvet worms) were considered a possible (intermediate) evolutionary link between the arthropods and annelids. The Onychophora are tropical invertebrates with an estimated 75 extant species that live on the forest floor. These organisms are segmented just like annelids and have a pair of nephridia (excretory organs). Both the female and male reproduction organs are found together...

Macroevolution

...aggress the old taxonomic group Para podia. Arthropods have taken over almost all the environment on the surface of the earth. Pieces supporting the evidence run that more species of the arthropods are multi celled animals, but that is only true for the expound species and more hobbyists are added to that list for insects. The phylum arthropod is divided in two subphyla, which are named according to their mouthparts but have several differences. The chelicerae’s, named for mouthparts derived from the appearance of the legs and the chelicerae, they do not have antennae found in the subphylum. The chelicerates have six pairs of appendages. One pair of chelicerae is followed by a pair of...

Chronic and Communicable Diseases

..., as well as other animals. They affect the body processes from taking place in the normal way. From the infectious diseases perspective, vectors are the agents that transmit organisms that cause diseases (Beaty, 1996). These organisms are responsible for carrying pathogens to different hosts, as they feed or move from one animal to the other. Vectors fall under the category of invertebrate animals and this category of animals comprise the arthropods (Gubler, 1997). It is imperative to note that vertebrates can also act as vectors, which can transmit diseases as invertebrates. For instance, skunks, raccoons and foxes are among the vectors that transmit diseases, despite the fact that they are vertebrates. They can...

Coral Reefs in the Philippines and the trophic levels and organism localization and interaction specific to this area

...(Rose, 2009). The groups include plankton feeder, corallivores, feeders on other benthic invertebrate, and piscivores. Plankton feeders includes the barnacles Tubastera sp. (Rose, 2009). The examples of corallivores include butterflyfish (Chaetodon ornatissimus), crown of thorns sea star (Acanthaster planci), and parasitic snails (Drupella sp.) (Rose, 2009). Moreover, examples of benthic invertebrates include cephalopods, arthropods like shrimps, and tritons (Charonia tritonis) (Rose, 2009). Examples of piscivores are molluscs and arthropods (Rose, 2009). These organisms usually live around the reef. At the top of this level are the tertiary consumers (Rose, 2009). The group comprises of larger fish...

Restoration of Agroecosystems: Predatory Invertebrate Abundance

...and environmental challenges, the development of agroecological technologies that emphasize the conservation-regeneration of biodiversity, becomes an urgent necessity (Zou, Sang, Bai, & Axmacher, 2013). According to the “enemies’ hypothesis”: predators and parasitic organisms are more efficient in diverse systems than simple ones. This hypothesis is supported by the increasing number of studies on agroecosystem restoration. For example, Zou, et al.,(2013) used predatory beetles (Coleoptera: Carabidae), to esatablish the relationship between plant diversity and the predatory beetles in Changbai Mountain, in China . A positive relationship was been determined between plant diversity and the abundance and diversity of the predatory...

National Parks Research Record--yalung river

...by animals in the ecosystem structure is that of energy distribution from one trophic level to the other. The animals are usually divided into different groups ranging from the primary consumers all through to the tertiary consumers and in some instances; the animals comprise the decomposers. In the phylum Mollusca, two most common animals found in Yarlung River are snails and slugs. Going by their scientific names, the two are called Helix aspersa and Arion distinctus respectively. Both the two animals are indigenous in the park as is the case in most places. Ideally, such animas are very important in the park’s ecosystem as they enhance diversity in the system and distribution of energy in the system. Other than the invertebrates,...

Experimental design on how to investigate the innate behaviour of woodlice Introduction

...hand, taxis behaviour is a behaviour in which an animal orients itself in an absolute direction in response to environment stimulus.2 Woodlice belong to the crustacean class. Most of these animals are terrestrial species and aquatic. It is believed that they exhibit an innate behaviour in that they tend to stay in wet and dark environment because they lack the characteristic waxy skeleton on their ex-skeleton like does most of the arthropods, thus tend to lose water easily when in dry conditions ()3. Woodlice are also good examples of organisms that orient themselves to humidity through kinesis. Woodlice also exhibit negative phototaxis. They have ocelli (light receptors). As a result, they do make directed movement...
