he Red Lionfish is eye catching but venomous and dangerous fish native to the west Pacific. This fish can grow up to 45cm or 17.7 inches in length. These fish are known for their beauty and their venom, they are also aggressive feeders and huge breeders. The Red Lionfish could possibly end up in the United States Atlantic Coast also the Gulf Of Mexico if the precautions are avoided. If this fish enter these waterways it would potentially end most life in the oceans and make it difficult for…

Some of us collected data for three parameters that describe the water quality: macro invertebrates, habitat quality, and water chemistry. Under water chemistry, we collected the waters dissolved oxygen, nitrogen and phosphorus, and pH levels. The group with habitat quality assessed the waters velocity, temperature, water depth, discharge, riparian vegetation, and substrates. My group studied the micro invertebrates that lived in the Chippewa River. All of these factors that we tested…

Shewanella haliotis is a species of rod shaped, gram negative, mo-tile bacilli that grow aerobically or anaerobically and produce hydrogen sulfide. Members of Shewanella were found in a variety of places, such as activated sludge, seawater, sediment, invertebrates, and fish, but are usually found in marine environments in warm climates. Shewanella can live on land, deep inside Earth, or underwater. As their habitat changes Shewanella changes with it, finding new ways to breath. This bacterium…

The river Frome has been the focus of interest for its importance as a SSSI (Sites of Special Scientific Interest) in the section between Dorchester and Wareham, for the presence of nationally rare invertebrate. It is protected under the Nitrates Directive and the Freshwater Fish Directive. The Upper Frome is also a Drinking Water Protected Area (Environment Agency,2011). The catchment area extend for 454 Km2. Its chalk geology, especially in the upper Frome, has a excellent capacity of absorb…

1. Shen X, Bourg NA, McShea WJ, Turner BJ. 2016. Long-term effects of white-tailed deer exclusion on the invasion of exotic plants: a case study in a mid-atlantic temperate forest. PLoS ONE. 11(3): 1-16. This article examines the impacts of white-tailed deer browsing on invasive plant species, both of these are biotic stressors that impact many forest ecosystems. Researchers in this study used a 4 hectare deer exclosure built in 1991 to study the influence of white-tailed deer, on the abundance…

Environmental Changes Affecting Organisms The world's climates is being affected by our way of life. Many of these changes aren't just hurting the plants and animals indigenous to these climates, it is also hurting us. Freshwater lakes and ponds, the Arctic ice caps, and humans are being affected by what is going on in the world. Many of the organisms in these freshwater lakes and ponds respond to the changes in their climate in two ways. They either can not respond, therefore, the number of…

I believe the decrease of wild hogs is necessary for three reasons. The first reason being they carry, and spread disease. The second reason is because they are overpopulated and breed up to three times a year having 12-15 offspring each time. The final reason is they destroy our crops, fields, and the equipment used to maintain them. When hogs are able to roam freely they can spread diseases. Although these infectious diseases may not be harmful to people, they are very dangerous for pets…

preserved in different ways. Trace Fossils – These are the preserved evidence of an animal’s activity or behavior, rather than the remains of the animal itself. Examples of trace fossils that have been found include: trilobite tracks marine invertebrate burrows ichthyosaur coprolites (fossilised excretion) Fossils with some organic material preserved – During Fossilisation, animal and plant remains can experience a variety of physical…

jellyfish live in warm tropical oceans such as the Atlantic, Pacific, and Indian Ocean. They are mostly in the ocean in a small to large group of other moon jelly that is called a bloom. Diet: They eat small plankton organisms like mollusks, marine invertebrate larvae, copepods, nematodes, crustaceans, young polychaetes, diatoms, protozoans and eggs. Predators: The main predator of a Moon Jellyfish is other types of jellyfish, usually of a different species. But moon jellyfish also have a…

enabled to move because of contractions and relations of muscles. Vertebrates and invertebrates movement is initiated by a combination of both passive and active forces (Linke, Granzier and Kellermayer, 2003). Passive forces in muscles are forces that develop when an inactive muscle is stretched from its resting length in resistance of the induced stretch. Passive force in the limbs movement of both vertebrate and invertebrates is the compensation force of the active force induced in the muscles…
