With the acknowledgement that biological monitoring was fundamental to charting ecosystem health (Great Lakes Water Quality Agreement ), EPA's program was developed for Lakes Erie, Huron and Michigan to: 1) monitor seasonal patterns, ranges of abundance and, in general, structure of the phytoplankton and zooplankton communities; 2) relate the biological components to variations in Cited by: 1.

1984 book and zooplankton composition, abundance and distribution: Lake Erie, Lake Huron, and Lake Michigan - [Joseph C Makarewicz; United States. Environmental Protection Agency. Great Lakes National Program Office.]. Introduction. Water quality has declined in Lake Erie's eutrophic western basin over the past two decades (Kane et al., ), characterized by an increasing severity in summertime harmful algal blooms and extent of hypoxic decline has prompted the revision of targets for spring total and dissolved reactive phosphorus loading in Annex 4 of the Great Lakes Water Quality Agreement.
The lake Lake Erie is 92 km wide at its widest point, km long, and has a surface area of approximat km2. It is the shallowest, southernmost, and warmest of the Great Lakes and is the twelfth largest lake in the world. Dis-charges from Lake Superior, Lake Michigan, and Lake Huron drain into Lake Erie through the Detroit River.

Date of U.S. Introduction: First discovered in Lake Huron in ; established in all of the Great Lakes by Means of Introduction: Accidentally introduced through ballast water Impacts: Has caused a decline in the population of zooplankton as a result of predation ; may also compete with some native species, such as perch and small crustaceans.

Seasonal phytoplankton abundance and biovolume trends in Lake Michigan, FIGURE 5. By examining changes in the phytoplankton and zooplankton in relation to water chemistry, evidence was found suggesting little change in the trophic status of Lakes Huron and Michigan while an improvement in the trophic status of Lake Erie was evident.

For Lakes Erie, Huron and Michigan respectively,and algal taxa 61 and 73 zooplankton taxa were identified. Based on indicator species and species associations, the plankton assemblage was consistent with a mesotrophic-eutrophic designation for Lake Erie, oligotrophic.
Spring phytoplankton declines, mainly attributed to a decrease in diatoms, are occurring in Lakes Huron and Michigan, a probable result of invasions by non-native zebra and quagga mussels that have reduced pelagic pelagicThe open ocean, excluding the ocean bottom and shore.
nutrients and selectively consumed phytoplankton. In this Data Set file, there are three separate spreadsheets: one each with data on algae, protozoans and zooplankton.
Plankton Diversity Data Set. Suggestions: Comparisons can be made by examining nearshore and offshore areas of Lake Erie, seasonal differences (May and August), abundance in different locations, and patterns using time or space. Since the early s, summer zooplankton communities have declined in numbers and biomass in Lakes Huron, Michigan and Ontario.
The zooplankton communities in these lakes have become increasingly similar to those characteristic of cold, oligotrophic systems, such as Lake Superior, which have low nutrient levels. Great Lakes - Great Lakes - Plant and animal life: Diatoms—microscopic algae with glasslike shells of silica—are the major forms of algae, although green and blue-green algae are abundant during the summer in Lakes Erie, Ontario, and Michigan.
Copepods and cladocerans, microscopic crustaceans, are important in the animal forms of plankton. Productivity in the open water of Lake Erie () was much less than the values observed in the Lake Erie and Lake Ontario near shore zones.
We are currently preparing a data set from the Western Basin of Lake Erie for the field year which will allow us to calculate productivity of zooplankton from that year for comparison with current. tributary to Lake Erie in Ohio, the Thames, and the Saginaw are widely recognized as having supported both historical and contemporary walleye populations of substantial abundance.
The other two rivers, the Huron, a tributary to Michigan's waters of Lake Erie, and the Clinton, have not supported large spawning populations of walleye. Methods. An in-depth comparison of phytoplankton and zooplankton from Lakes Erie, Huron and Michigan is presented based on extensive lake-wide surveys during spring, summer and autumn of This comparison was achieved by the application of standard and consistent identification, enumeration and data-processing techniques of plankton along north-south transects in Lakes Huron and Michigan.
The crustacean zooplankton communities in Lakes Michigan and Huron and the central and eastern basins of Lake Erie have shown substantial, persistent changes since the invasion of the predatory.
Summer microcrustacean zooplankton grazing rates in the range of 6%–15% have been documented in Lake Erie (Wu and Culver, ), Saginaw Bay of Lake Huron (Bridgeman et al., ), and Lake Champlain (Levine et al., ). Lake Erie is composed of three basins: a shallow western basin (mean depth m) west of the city of Sandusky, Ohio with many natural limestone reefs, shoals, and islands; a deep eastern basin (mean depth m) east of Erie, Pennsylvania; and a large, flat central basin between Sandusky and Erie (mean depth m) () (Figure 3).The western basin in 13% of the area of the lake and 5%.
Abstract. Lake St. Clair phytoplankton and zooplankton abundance and composition was analyzed during the period of May to September In addition, size-fractionated primary productivity and other limnologi-cal parameters were measured.

Lake Huron, the second largest of the Great Lakes in terms of surface area (Beeton, ), is unique in that near coincident changes in phytoplankton, zooplankton, and forage fishes occurred around that have generally persisted to the present. While concentra tions vary between lakes, the pattern observed in Lake Michigan, that is, a general decline, with peaks in and is also observed in Lakes Superior, Huron and Ontario.
In Lake Erie walleye, mean dieldrin concentrations decreased from ~g/gin to ~g/ginincreasing to ~g/ginthen declining to 0. Lake Erie is the fourth-largest lake (by surface area) of the five Great Lakes in North America, and the eleventh-largest globally if measured in terms of surface area.
It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence its deepest point Lake Erie is feet (64 metres) deep.However, Grossnickle () found that Lake Michigan opossum shrimp feed primarily upon phytoplankton.
This suggested a lack of Mysis reliance on herbivorous zooplankton such as Daphnia. Lehman et al () documented a lack of Mysis reliance on Daphnia in Lake Michigan and discovered that there is little spatial/temporal overlap between.
The basic difference between phytoplankton and zooplankton is that the word ‘phyto‘ is used for the small plants like diatoms and algae and word ‘zoo‘ is used for the small animals like tiny fish, crustaceans, which are the weak swimmers and just move along the currents.
The word “plankton” refers to the smallest aquatic plants or animals that float and drift in the limnetic zone.
