Micro Invertebrate Species Richness At Flinders Lake

The macroinvertebrates graph (figure 2) represents the diversity of species inhabiting the Baldwin Swamp. In 2009 the Baldwin swamp was flourishing with a large diversity of species. A total of 33 macroinvertebrates, 8 species were recorded. At this time the baldwin swamp was healthy, abundant in life and the ecosystem and food webs were unaffected by the floods. Whereas 3 weeks after the floods swept through there were little to no range of species of macroinvertebrates. There were a recorded amount of 2 Damselfly Nymph and 1 waterboat man. A theory to why these two

The bar chart was used to compare the number of species in each transect. In transect A, there were 5 different species. The species in this area were mostly grass, forbs, moss, bugs and beetles. Bugs and beetles made up a small population of this transect. In transect B, there were also 5 species. The species were mostly grass, shrubs, forbs, moss and bugs. In this transect, shrubs were found which makes transect B more diversed than A. In Transect C, 8 species were located in this area. The species included shrubs, grass, fobs, evergreen, trees, dirt, bugs and spiders. New species such as evergreen, trees, dirt and spiders were located in this location. Therefore the test that diversity happens through ecological succession was

The aim of our excursion to Hastings Point, New South Wales was to study the biodiversity and ecology and to see how these organisms behave in their natural habitat and surroundings. There will also be information collected about a variety of different organisms as well as population counts and observe how they have adapted to the species surrounding environment. The excursion will also be an opportunity to gather information on

Silvershell Beach is the home to many different aquatic species and other forms of wildlife. Last lab block the class and I went into the ocean at Silvershell beach and took seven different seine net samples. With each sample we took, we noticed a variety of different organisms. As we moved around different areas of the ocean, we would come out with changing species and number of species that we did not find in other areas of the water. Species we found included sea robin, hermit crabs, moon jellies, minnows, shrimp, eels, and more. Sample one and two were taken from around the same area in the water and there was a reappearance of three of the species. In sample one we found hermit crabs, minnows, moon jellies, and a sea robin. In sample two

The Ontario Benthos Biomonitoring Network was created to assess the quality of aquatic environments and ecosystems using benthos organisms as biomarkers (Ontario Ministry of the Environment, 2007). Exclusively used in Ontario, this biomonitoring program assesses ecological function and condition of streams, rivers, lakes, and wetlands across the province (The Dorset Environmental Science Centre, 2017). The OBBN protocol is ideal for assessing water quality because of the use of aquatic macroinvertebrates (Borisko, et al. 2007). Since macroinvertebrates are easy and inexpensive to collect, determining water quality can be conducted continuously over the course of the year, across many locations (Borisko, et al. 2007; Ontario Ministry of the

For the convenience of the students, a packet for recording the stream’s content and results was provided. On the first and second page, tables for seeing the taxa types of aquatic macroinvertebrates found were laid out, and students were to check the boxes with the names of the taxa they found in this area. Students entered the stream with a large water strain, and put dirt from the stream and carried it out of the stream to be examined. After observing several catches from the stream, the group one taxa findings included Stonefly nymph, Mayfly nymph, and Dobson fly nymph.

diversity is low because only one area was sampled so this could account for the species being the same. If

Different aquatic invertebrates live in different micro habitats (smaller habitats) at Lake Tonetta. Some live on the surface of the water. Others live in the bottom of the lake, or deep within the sediments at the bottom of the lake. The water pH is important because they only can live in a specific pH 6.5-7.5.When we visit the lake our group checked the biodiversity (The variety of plants and animal species in an environment)of Lake Tonetta by counting the aquatic invertebrates in a sample obtained using dip nets and bottom scrapers. During our trip, we found beetles, snails, worms ,

At this station, we had to go into the creek, pick out rocks, and observe and identify the animal life living on that rock. Animals that live in the water need dissolved oxygen so they can breathe under the water. The more turbulent the water is, the more dissolved oxygen can be found in it. The amount of dissolved oxygen in a body of water will determine the type and number of macro-invertebrates that may live there. There are three groups of animals that you could find in the Conodoguinet Creek. Group one is called stream insects and crustaceans. These are pollution sensitive organisms, which means they cannot exist in polluted waters. Group one organisms are only found in good quality water. Some examples of these organisms are mayflies, gilled snails, water penny, or a stonefly(shown in figure 8.) The next group is the organisms that are somewhat pollution tolerant, which means they can be found in good or fair quality water. Crayfish, dragonflies, and clams are all examples of group two organisms (shown in figures 3, 6, and 9.) Group three organisms are pollution tolerant organisms. This means they can be found in any quality water. Some examples of group three organisms are pouch snails, pond snails, orb snails, and leeches. When I conducted this experiment, I found seven group one organisms, seven group two organisms, and five group three organisms. Macroinvertebrate is another word for organism.

6) There are several advantages and disadvantages to identifying benthic macro-invertebrates at different taxonomic levels. In this assignment metrics were calculated to the 27-group level (which consists of phyla, classes, orders and families) as well as the family level. There were slight differences in the calculated species richness and Biotic Indexes using these different identification levels. This is an indication that taxonomic resolution can affect bioassesment outcomes.

Only one method of planktonic sampling was used so comparison with another method of sampling cannot be done. It is safe to assume that the most appropriate method of sampling in these areas was previously determined by the lab instructor. Isolation of organisms in the samples was met with some difficulty as there was very little life to be observed. Once isolated however, a general identification was simple with the use of the “quick picks” section of the Marine Invertebrate Zoology Lab Manual. One particular organism isolated from the “T-docks” samples, a foraminiferida, was chosen for scientific drawing (Figure 1).

The variations of tidal levels have created different degrees of sun and air exposure that have resulted in three zones, generally, the supra-littoral zone, littoral zone and the sub-littoral zone (See Appendix A, Figure 3). Diverse animal and plant organisms excel at surviving and dealing with different degrees of abiotic and biotic factors and as a result the rocky shore ecosystem is comprised of a series of bands known as vertical, or in this instance, intertidal zonation (See Appendix A, Figure 1). Abiotic stresses such as light intensity and wave action typically set the upper boundaries where as biotic stresses set the lower boundaries and limit the distribution of many organisms to particular strata (See Appendix A, Figure 2). It is due to the species distribution among the different zones that the rocky shore ecosystems cannot be defined as a uniform habitat, rather a dynamic and complex one (Bamfield Marine Sciences Centre, 2013).

Heath Creek, located in Northfield, MN, was sampled at four locations: A, B, C and D in which each location was measured for depth and sampled for macroinvertebrates. Locations A, B, C, and D were respectively labeled according to the downward flow of Heath Creek into Cannon River, with Location A being farthest away from the end and Location D being near the merge of Heath Creek and the Cannon River. In every location, an area of 21 meters was measured and divided into three sections of 7 meters. In each section, the depth for the deepest and most shallow sites were measured, followed by a collection of two separate representative samples of the deepest and most shallow sites. Sampling was performed through a minute of D-net jabbing and another

The EPT Index looks at Ephemeroptera, Plecoptera, and Trichoptera (mayflies, stoneflies, and caddisflies, respectively) as indicators of aquatic community health. The idea behind the EPT Index is that healthier streams have a greater richness of species as many species of macroinvertebrates are intolerant of pollutions and thus will not be found in low quality bodies of water (Lenat 1988). Previous studies have found that EPT
