Effect of temperature Results In this experiment, results from two Procambarus propinquus (crayfish) were collected to observe the difference in oxygen consumption at different acclimated temperatures. These cray fish were collected from Medway Creek in London, and acclimated to their new environment and temperatures. The crayfish were exposed to the cold environment having an average temperature of 7° or warm having an average of 22°. An unpaired, two-tailed t test was performed to determine if there would be a change in O2 consumption between 2 individual crayfish.…
Compensation is the maintenance of the levels of physiological processes, despite changes in temperature. This experiment was coordinated to determine whether crayfish will show metabolic compensation when acclimated to various temperatures. The findings of this study show that temperature had no effect on crayfish oxygen consumption. The oxygen consumption for both the warm and cold acclimated crayfish was almost the same, despite the opposite direction of the temperature change. The results of this study therefore support the hypothesis.…
Captive Killer Whales Blackfish is a movie about an orca named Tilikum who was captured at a young age and taken to perform at Sealand. Within a year and a half he was moved to Seaworld for breeding purposes and because Sealand shut down. Tilikum soon became a great attraction and everyone wanted to see him and all the trainers wanted to train him. They all thought Tilikum was an excellent whale, but that is because they were never told that anything bad happened.…
Found in lakes, ponds and any area that well have any rocky substance or logs. Rusty Crayfish, is an invader that has invaded lakes in the northern reagan. There robust claws that most members of the Orconectes genius don't have makes then an unique but dangerous species . It was first indentificaded as “Rusty ” in Belgrade, great pond in the late 1968. It curentaly was founded in Michigan, Massachusetts, Missouri, Iowa, Minnesota, New Mexico and parts in New england expect wisconsin, canada and Ontario.…
This creature has many abiotic and biotic factors. The abiotic factors that it has are dirt, rocks, tumbleweeds and sticks. The…
These outrageous and unexpected invasive species. they are the monster goldfish and the wild boar of how these innocent creatures became such monsters. The goldfish can be invasive species. From source 1: The Monster goldfish is a normal goldfish that got dumped by the owner but then grew and grew and grew until it was huge!…
The majority of the invasives listed, however, are living in aquatic ecosystems. These aquatic invasive species live in and around lakes, waterways and wetlands. Some species arrive when people illegally empty bait buckets or aquariums into lakes and waterways. Many others “hitchhike” on watercraft, bait buckers, and other recreational gear from one habitat to another. One such known hitchhiker is the zebra mussel, given the scientific name Dreissena polymorpha.…
Crayfish can be found in Australia and many other parts of the world but most commonly in North America, specially U.S.A. Due to the EPA foundation, they are not extinct. EPA has used liming in many lakes in order to save many aquatic animals. If EPA didn’t exist, many aquatic animals would be classified as extinct, as they cannot survive in a toxic environment. In 30 years, we believe crayfish are not going to be classified as extinct, as there are many programs trying to solve the problem, and some of their solutions have already worked. For instance, the lake in New England.…
Millions of insects also eat the leftover salmon, bolstering invertebrate populations, which in turn feed birds and other small forest creatures. Dr. Reimchen's team found insects with more than half their nitrogen coming from an ocean source, and a greater abundance and variety of both insects and plants near salmon bearing…
This causes a destruction of all the species in that area. The species that I chose to research on is the Blue Catfish. This is a species…
Although the scale bug is a huge pest towards the marsh, it is not the only threat. Another threat is the Nutria, a semi-aquatic rodent, that was brought in from South America. It chews on the marsh plant by its roots, damaging abut 6,000 acres per year. These invasive species are bad for the business in Louisiana. The canes are an aquatic habitat for the young redfish, which is the top fishing catch in the state.…
Invasive species can set up unfavorable relationships with the native species in the invaded ecosystem. Kornis, Sharma, Jake Vander Zanden, and Ricciardi, the scientists behind the study “Invasion Success and Impact of an Invasive Fish, Round Goby, in Great Lakes Tributaries“ (2013), stated that some causes for calamitous relationships are because of “diet and habitat overlap” (p 186). When competing for resources in an environment in which native species typically had no issue, the host species often have a harder time winning this competition. This ultimately leads to a lack of abundance. An invasion of a cladoceran in the Black Seas during the 1980s resulted in such an occurrence.…
The Blue Crabs Promise Summer Excitement For those living in Charles County, MD, one of the greatest summer pastimes is catching The Blue Crabs play a game or two. The Blue Crabs are a minor league baseball team that offer excitement for their fans all year long. The team plays from April through August, which gives residents plenty of time to catch several games.

These small killers have a really large mouth and claws, which they use to strip their prey. They are very aggressive. Eating anything their size or smaller including small fish. This limits the food sources for the larger fish leading to a decrease in population of native species. The best way to control this invasive species is to be knowledgeable of the waters in which you roam.…
