Question: How Do Zebra Mussels Change The Biotic Condition In An Aquatic Ecosystem?

How do zebra mussels impact the biodiversity of the aquatic communities that they invade?

Zebra mussels (Dreissena polymorpha) are not only an extremely aggressive invasive species, often dominating water bodies they invade, they are also very effective ecosystem engineers, altering the environments they invade. They are effective engineers, altering both ecosystem structure and function.

What biotic factors affect zebras?

These are the main factor that influences zebras. These are factors such as light, temperature and water. Zebras need to live in a very hot location with high light levels. However they also need a large amount of water to stay hydrated because of the heat.

What impact do zebra mussels have on the environment?

Zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they attach to–and incapacitate–native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes.

How has the invasion of zebra mussels in the Hudson River affected one biotic and abiotic factor in the river ecosystem?

Zebra mussels are filter feeders. As they fed, they filtered particles out of the water, including suspended solids and organic materials, as well as organisms such as phyto- and zooplankton. As a result, light penetration increased in the Hudson River. Increased sunlight promoted the growth of rooted aquatic plants.

Are zebra mussels good for anything?

Water clarity Mussels are filter feeders, which means they feed by clearing nutrients from the water passing through them. The rate of reproduction and spread of zebra mussels make them efficient cleaners of Great Lakes water, but whether that’s a positive or negative thing depends on who you’re asking.

What are the negative effects of zebra mussels?

Zebra Mussels are especially harmful for native mussels, many of which are species at risk. They outcompete these species for food and will attach themselves to native mussels, suffocating them.

Are zebra mussels abiotic or biotic?

Along the Hudson, the key biotic factors are phytoplankton, zooplankton, bacteria, crabs, fish, and, of course, the zebra mussels.

How do biotic and abiotic factors interact in an ecosystem?

Sunlight, air, soil, rock, minerals, water, etc. are all biotic factors. Air also interacts with plants, helping them grow by providing a source of carbon (CO2) and other nutrients. In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients.

What eat zebra mussels?

Several organisms, such as diving ducks, crayfish, eel, common carp, pumpkinseed, European roach, and freshwater drum, have been found to consume zebra mussels. Several other fish species are listed as potential predators of zebra mussels because of their historic consumption of other native molluscs.

Will zebra mussels ever go away?

Zebra mussels were discovered on Pelican Lake in 2009 and some of those found were determined to be one or two years old because of their size. Zebra mussels have a 3 to 4 year life cycle in our area and go dormant at less than 55 degrees. They cannot survive freezing temperatures.

Are zebra mussels bad for humans?

EAST LANSING, Mich. Inland lakes in Michigan that have been invaded by zebra mussels, an exotic species that has plagued bodies of water in several states since the 1980s, have higher levels of algae that produce a toxin that can be harmful to humans and animals, according to a Michigan State University researcher.

What are the pros and cons of zebra mussels?

Pros and Cons on Zebra Mussels

  • They will plug up water intakes.( this will create a job for someone)
  • They will clean up the water so much, that weeds will grow.( Great, then the fish will have habitat, fishing can only improve)

Are zebra mussels really invading answers?

In the absence of their natural pathogens, parasites, and predators, the zebra mussel populations in the Great Lakes has grown enormously and are now invading eight major river systems, including the St. Lawrence, Hudson, Mississippi, Ohio, Illinois, Tennessee, Susquehanna, and Arkansas rivers.

Do zebra mussels eat zooplankton?

Zebra mussels are suspension feeders, eating phytoplankton, small zooplankton, large bacteria, and organic detritus by filtering the water and straining out the edible material. Phytoplankton and zooplankton form the base of the aquatic food web, so many animals depend on them for survival.

What are three biotic factors that scientists are monitoring in Hudson River to study the impact of zebra mussels?

Along the Hudson, the key biotic factors are phytoplankton, zooplankton, bacteria, crabs, fish, and, of course, the zebra mussels. These scientists are collecting samples of tiny zooplankton from the river using long, fine mesh nets.
