I. Introduction The Schistocephalus solidus parasite was discovered and isolated from the cold areas of the Eastern and Western regions of North America (Poulin‚ 2000). This parasite is also common in the areas of Canada‚ Europe‚ and Eurasia. Schistocephalus solidus is a cestode that has been established to infect over 400 different types of bird species (Barber and Scharsack‚ 2010). The different types of the bird’s species form the definitive hosts of the parasite. Schistocephalus solidus is also

Pitch: This article is written to inform the reader of the issues pose by crown of thorns starfish on coral reefs. The target audience is the general public who may view coral reefs as a tourist destination. There is a need to warn about crown of thorns as research shows that it causes more destruction to corals reefs than bleaching or other disturbances. More details on how these starfish population boomed are given in the article‚ revealing both natural and anthropogenic factors. The article however

filariasis. A mosquito‚ after biting a person that currently has the disease‚ carries the larvae of the parasite that causes the symptoms and bites someone else‚ thereby passing on the larvae‚ or microfilariae‚ into the next host. Most people that are infected do not show any clinical signs or symptoms of the parasite‚ even though their lymph system is being damaged. (World Health Organization‚ n.d.) As the larvae circulate through the blood system‚ they mature into adult worms‚ migrate to the lymphatic

catastrophes among ecosystems‚ tests need to be performed in essence to keep the ecosystems from being harmed. If‚ for example‚ diatoms and dinoflagellates were to be removed from the food web due to certain chemical factors many organisms (mollusc larvae‚ copepods‚ etc) will not have a food supply therefore resulting in the extinction of many organisms. This leads to disruptions in the ecosystem. The preservation in estuaries is vital for the study of past life and climates‚ as well as present living

attached to the females cuticle. The larvae are free living and go through at least 6 moults of their cuticle before they reach maturity. The eggs take from 15 to 80 days to hatch. The larvae are free swimming and look like the Kinorhyncha with scalid spines around their heads and a set of oral stylets that can be everted or retracted into the body cavity‚ and not at all like their parents. They are parasites of invertebrates‚ though not necessarily aquatic ones. The larvae have a better developed digestive

These components affect living organisms in many ways. Some of the soluble components and emulsions are poisonous‚ particularly to small organisms that do not have protective coverings or shells- Fish larvae‚ single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. In shallow water these toxic substances may directly kill algae‚ coral and sea grasses. These components may also be passed in the food chain or directly ingested or absorbed

foxes or dogs-- the adult female mosquito becomes infected with the microfilariae that becomes a larva within 10-14 days. The mosquito then deposits this parasite on the surface of the animal’s skin. The larvae enter the host through the mosquitos bite wound. Once inside it takes 6 months for these larvae to become adults in the main pulmonary arteries and right ventricle of the heart. At maturity‚ heartworms can live inside the host for five to seven years. Because these worms can live for so long‚ each

Question: How are Hawaiian honeycreepers well-adapted to their specific environment but not to other types of environments in Hawaiʻi? Context/Background: Well‚ it could be the concept of evolution. Once a species got here‚ it became isolated from its population during its generation. Genetic factors overtime then cause the Hawaiian Honeycreepers to adapt to their surroundings and they became known as a new species. There are many different types of Hawaiian Honeycreepers and they all are
