E.coli In Fish

E.coli presence in aquaculture attributed to the contamination of the water by animal waste [28]. Its isolation from fish samples indicates fecal contamination of the water resulting from the livestock manure. The contamination of food and environment with a bacteriological condition like E.coli is almost originated from human and animal feces. Isolation of E.coli was done by taking swab samples from the skin and muscle of fresh fish. Isolation of E.coli from fish muscle and skin has a statically significant...

Evolution Of The Brown Rat

Present Variations Variations in Brown rats; captivity versus in the wild For over a century brown rats (Rattus norvegicus) have been used by humans for many reasons. Originally, they were used by rat fanciers (those who breed rats as a hobby for their unique coats etc) and later by scientists who still use R. norvegicus to this day for their research where they gained the name of “model organism”. Wild animals, including R. norvegicus, are more active and reactive than...

Koala Populations Are A Threatened Species

Climate change impacts have resulted in ecological changes that cause physiological stress on species and can affect population dynamics. Sources of stress include biotic factors such as predation and competition, as well as abiotic factors such as extremes in temperature and increased frequency of fires and drought. For example, global temperature levels have and are expected to rise, with eighteen of the 19 warmest years occurring since 2001. Temperature increase and lack of available water may lead to impacts on...

Problems Of Forced Migration Of Emperor Penguins

Emperor Penguins Emperor penguins migrate annually from the West coast of Antarctica to their breeding grounds. This journey has a distance of 60-100 miles and the main reason is for breeding. However, recently some Emperor penguins are migrating because of climate change and limited amounts of food. The migration takes place during the month of March. Around 595,000 Emperor Penguins migrate every year. They do this in such large numbers so they stay safe when predators such as seals, target...

Researching Of The Causes Of Dolphin Extinction

Extinction happens when a plant or animal species ' last individual dies out. This can occur naturally, likely due to climate change or other factors, or due to human activity such as overhunting or habitat destruction. Marine animals are aquatic mammals that rely for their life on the ocean and other marine ecosystems. Researchers are now using a comprehensive study of marine animals that have died out over the past 23 million years to determine which animals and ocean habitats...

Using Rats In Scientific Research

Living organisms have systems which all work together to enable survival. In the animal kingdom, rats and humans are both mammals, and they have very similar systems and organs in their body. A mammal is a warm-blooded vertebrate animal which has fur or hair, gives birth to babies, as opposed to laying eggs, and feed their young milk. The systems which enable survival in mammals include the circulatory system, musculoskeletal system, digestive system, excretory system, respiratory system, reproductive system and...

Key Role Characteristics And Features Of Butterfly Wing Patterns

Evolutionary biologists have, for a long time, been interested in the butterflies' colorful wings. The coloration patterns on the wings of a butterfly have many roles, which include the attraction of the male, concealment, mate identification, and warning signals. Given that the coloration on the wings mostly plays several roles simultaneously, there is a possibility that there exist conflicts between how different signals express themselves. For example, the ventral wing side coloration is mainly used to avoid predators through camouflage,...

Role Of Honey Bees In Ecosystem

A Keystone species, like an animal or plant helps define and shape an entire ecosystem. These species are a key function to an ecosystem. Without keystone species the ecosystem and habitats would dramatically differ and change or, would not exist at all, species who depend on those environments would not exist either. If keystone species didn’t exist there would be no ecosystem for other species to live in. Many of the animals and plants we rely on as food sources...
