Zooplankton

Large decreases in the algae population will most likely impact the bay ecosystem by killing off organisms and plants. Algae is a crucial plant in the Chesapeake Bay that needs to steadily grow to keep the animal population consistent. Bay grass, also known as underwater grass, grows in the superficial areas of the Chesapeake Bay. It is crucial to the environment because it absorbs extra nutrients, shelters small fish, and keeps the water looking less murky. Like Algae, Bay grass provides…

Next, I will assess zooplankton biomass at each of the three sites using a very fine, vertical plankton net which will be lowered until the bottom is felt. At this point, depth will be recorded (ft) and secchi disk will be vertically retrieved. Once on the net canister, the zooplankton will be gently scraped off the walls, and any individuals still holding on will be flushed off using a squirt bottle filled with distilled water. Zooplankton will be placed in a marked jar of ethanol…

reproduction, and safety mechanisms of marine life. One significant example of this is the effect excess carbon can have on zooplankton. Although zooplankton are a small part of the ocean, they end up feeding most aquatic mammals bigger than them. A variety of experiments show that higher levels of acidity result in dissolving zooplankton 's shells. This could lead to zooplankton living in tropical areas to become extinct by the end of the century, which would result in a food shortage for many…

Hassenzahl, is “an organism in an environment” (43). Phytoplankton, Zooplankton and Benthos are all living or biotic organisms this study examined in the starch factory stream. Phytoplankton are, according to Raven, Berg and Hassenzahl, “free-floating photosynthetic algae and cyanobacteria that form the base of most aquatic food webs” (124). Phytoplankton is green when examined in a microscope while zooplankton is not. Zooplankton are defined as “nonphotosynthetic organism that include protozoa…

while microzooplankton (100–140 μn) are important recyclers of nutrients, dominant grazers of phytoplankton, and key link in the microbial loop (Conroy et al., 2016; Uitto and Hallfors, 1996). Therefore, understanding this relationship between zooplankton and grazing will allow scientists to be able to understand the primary production and rate of energy flow through out food webs all over the world (Frost, 1972; Conroy et al., 2016) In order to measure both meso- and microzooplankton feeding…

• Applied taxonomic skills to differentiate various zooplankton of the James River. • Helped in the care and creation of zooplankton cultures used in experimentation. Works and Presentations Kristine Grayson, Dylan Parry, Derek Johnson, Nora Krajah, Dominique Grim (November 2013). Local adaptation in larval performance across the…

they? Well they are small organisms that float in large numbers in either salt or fresh water. They belong to three groups called phytoplankton, zooplankton, and bacterioplankton. Plankton are a significant food source for blue whales, shrimp and jelly fish. Bioluminescent plankton belong to phytoplankton which use sunlight to make its own food, and zooplankton which feeds on phytoplankton and other small organisms. Bioluminescent plankton can be seen in oceans all around the world such…

example some fishes swim using their fins, while other aquatic animals don’t swim but walk. Of all the variety of marine animals I would like to address jellyfish and their lifestyle since they are very intriguing animals. Jellyfish are a type of zooplankton part of the phylum cnidaria, greek word for “stinging nettle” and the class scyphozoa, Greek word for “cup” referring to their body shape. They’ve been on earth for more than 700 million years, resulting in more than 2000 species. Their…

Zooplankton are an important part of the food chain and their decline can lead to a change of organismal relationships (Mahassen, El-Deeb Ghazy, 2011). Daphnia, a type of zooplankton, are at the bottom of the food chain in freshwater systems. If toxicity of the water is too high, it can affect these organisms, which will then affect others…

The movement and distribution of marine organisms has always been a main focal point of marine studies. With organisms such as Ctenophora, what role does temperature and rainfall play in their movements? To get a better understanding of how population densities change with weather, samples were taken during different periods of precipitation and temperature; rain the day before, clear the day before, warm temperatures, and cool temperatures. In the end, there were minor differences between the…
