Responses of intertidal invertebrates to rising sea surface temperatures in the southeastern Indian Ocean by Fred E. Wells● Names ● Turn in one copy per group Biology 1232K: General Biology II Lab 13: Ecology Lab II 75 Often overlooked in general discussions of terrestrial communities are the organisms that live below ground. Soil communities can include various microbes such as archaea, bacteria, fungi, algae, and protozoa, as well as a variety of microinvertebrates including springtails, mites, nematodes, and earthworms. These organisms provide several ecological functions including decomposing organic matter, fixing atmospheric nitrogen, and enriching the physical and chemical conditions of soil. used. Pine forests tend to have a closed canopy of one or more pine species and relatively little undergrowth. They benefit the most from well-drained sandy soils that are slightly acidic. Common among the pines in the SE United States are loblolly pine and slash pine. The tough pine needles that fall under the trees decompose very slowly and produce a thick mat, both of which contribute to the reduced…
- INTRODUCTION: Quadrat sampling is a classic tool for the study of ecology, especially biodiversity. In general, a series of squares (quadrats) of a set size are placed in a habitat of interest and the species within those quadrats are identified and recorded. QUESTION: What are the advantages and disadvantages of a quadrat sampling method?For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.The diagram below shows patches of habitat that are either colonized (red dots) or not colonized (green dots). Which conclusion can be drawn from the data? 100 10 0.1 0.01 Patch status in 1991 • Colonized • Not colonized 0.01 0.1 10 100 Distance from nearest occupied patch (km) A. Patches that have the smallest area and are closest to another occupied patch are most likely to be colonized. B. Patches with the smallest area are most likely to be colonized; the distance to the nearest occupied patch does not affect colonization rates. C. Patches that are very close to another occupied patch or that have large areas are most likely to be colonized. D. Patches that have the largest area and are farthest away from another occupied patch are most likely to be colonized. E. There is no relationship between patch size and rate of colonization. 1.

- LAB: THE LESSON OF THE KAIBAB INTRODUCTION: The environment may be changed by the things within the biotic community, as well as relationship between organisms and the nonliving environment. The carrying capacity of an ecosystem is the maximum number of organisms that an area can support over time. The density of a population may cause huge changes in the environment so that the environment becomes unstable for the survival of that species. Humans can mess up natural selection and have either a positive or negative effect. OBJECTIVES Graph data on the Kaibab deer population of Arizona from 1905-1939. Analyze the factors that caused the changes in the deer population. PROCEDURE: Before 1905, there was an estimated 4000 deer on almost 30,000 hectacres of land on the Kaibab Plateau in Arizona. The average carrying capacity of the land at that time was estimated to be about 30,000 deer. Being concerned about the low number of deer, President Theodore Roosevelt created the Grand Canyon…Do a Travelogue Situation: You are conservation biologist working as a part time reporter In a local television station. You are assigned to make documentary slides that promote Philippine diversity. Your task is to create slides that will describe the causes and ettects of biodiversity loss in the country. You may also include the advantages of achieving high biodiversity to maintain the stability of an ecosystem. Your work will be evaluated according to organization, content, and accuracy of science concepts.The diagram below shows patches of habitat that are either colonized (red dots) or not colonized (green dots).

The students hypothesized that there would be more insect biodiversity in the leaflitter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with alight shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled containerbelow the funnel, and the species were identified using magnifying lenses and a key
