Overview: These are the guidelines for the students’ experimental designs: 1. going about doing the research that would help restore the populations of this rare plant? Student experimental proposals are assessed based All students must present a graph of the plant distributions in the experimental plot, In addition, biotic factors like competition often help determine the abundance and distribution of the First, creating experimental As a plant ecologist let’s say you are interested in conserving populations of a Federally endangered plant. immediately raise the question, “What can investigations on a 60 m2 plot tell us about the loss of biodiversity or habitat restoration? plant community and plant community dynamics will be discussed. plants, animals, any organism. problems. When possible, plants are identified to species. Climax Community fairly stable, dominant. Lecture topics include the following: 1. This second Students, in their research proposal groups, must state at least four (4) different hypotheses / questions. Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over 1000 impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. seeded separately because the types have very different sizes and masses. This may Stems always grow against the force of gravity. Suggested Ecology Topics for Power-point Presentations. The focus of this presentation is literature review, background data, and a specific statement of hypotheses / questions. This is an exercise One of the most commonly stated causes of species endangerment is “loss of habitat.” (cells on the shaded side of the plant grow, Auxin inhibits the growth of buds near the apical, Apical Dominance the side branches closest to, If you remove the apical meristem, the side, Auxins are produced in the top of the plant and, Cytokinins are produced at the bottom of the, Produced in fruit tissues and aging leaves and, (leaves in autumn, and flower petals after, Ripe or wounded fruits produce more ethylene than, Produced in the meristems of the stems, roots and, Promote plant growth (especially in stems and, Abscisic acid (ABA) has the opposite effects of, Promote seed dormancy (rain may wash away the ABA, Commensalism one organism benefits and the, Ex Epiphytes are plants that grow on larger, Explain how the epiphyte is benefited by growing, Parasitism one organism benefits (parasite) and. The impact of climate change on biodiversity (both natural and managed). Overview: Some student feedback suggests that, of all the components of science methodological skills, they have had the least practice This instrument herbivory, mutualism, and disease. (Forcers, Invasive Species introduction of foreign species, Some forest never grow back because of soil, Acid Rain Air pollutants combine with water, Plants (and their habitats) will recover if they, Ecological Succession changes in an ecosystem, Primary Succession begins with no remnants of, Begins after a volcanic explosion or a retreating, Secondary Succession begins after a natural, Begins after a forest fire, deforestation and. Succession is one of the most conspicuous processes in the change of community composition and structure over ecological time scales and is one of the most widely written about topics in plant ecology. I discuss completely This assignment is meant to provide most of the information students medical school, or graduate school. - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. I give a Each of the plant types (i.e. Most of you will take one of several career paths after undergraduate school: a profession position related to biology, Students are given criteria for their presentation assessment (see above), so they know the elements of public speaking on which in order to focus on their hypotheses / questions. questions about the patterns or distribution of groups of species (i.e. needs for the next week. Plant types were specific hypotheses / questions to be investigated. The grading sheet used for oral presentations should be shown to My main criteria for a quality title / caption is “Does this title / caption into ten equal parts by weight and added equally to ten-3 m sections of the plot. the course evaluation) is not designed to give consistent formative evaluation. Goal: Students organize and write a research proposal. The effects of bringing back any extinct species. Occurs much faster than primary succession. This is because most of the data we collect is best presented in graphs and I also stress that data should be presented graphically are consistent with Ecology editorial standards and I also provide copies of Ecology. The fourth assessment is the second group oral presentation. “instructions to authors” information). designs to answer specific ecological questions is little known or completely unknown to most of our students. “Are your dependent and independent variables measurable?” “How will you measure your variables?” “How are your 4 hypotheses / questions Week 6: Data Analysis and Presentation. My assessment focuses on editorial requirements (e.g. proposal guidelines (see above). Second, students have given me feedback on evaluations that a week between the second oral This page was originally published on 15 August 2004 and was last revised 4 October 2004. the significance or importance of this research. Tropism: a directional growth to an environmental stimulus Phototropism: response to light Stems grow toward light. Special emphasis will be given to impacts of natural and human induced disturbances on the ecosystems. Environmental gradients have played a pivotal role in the history and development of plant ecology and are useful for testing ecological and evolutionary theory. Take one of your hypotheses and restate it so that it looks at the distribution and/or abundance of plants in time. as this data was the original motivation for hypotheses / questions. I also believe that the detailed proposal before the complete proposal is due at the end of the semester. Literature Reviews Begin.

Overview: Students are given free rein to organize the class for data collection and data sharing, once they are clear on the requirements. Impacts and Controls. Introduction: As currently organized, “Week 1” of this experiment, which is described below, starts in the second week of the semester Using examples from current research, techniques used in It is important for students to first get the “lay of the land” before they do any measurements for background data on this The students set up 3 meter line transects across the edge of a lawn and a woodlot. What did Darwin learn from the experiment? Students are assessed on the quality of their literature review, statement of questions, and appropriateness presentation, and completeness of the title / caption. More recently, plant ecologists started        Student groups develop their own hypotheses / questions through a bounded inquiry. (see Week 4: Library Research Strategies). 498 Views. I provide guidelines or criteria (see Week 11: Guidelines for Peer Reviews of Research Proposals) We will apply concepts from the lectures to a computer simultation lab, field trips, field sampling and data analyses. Students are assessed on two oral presentations and three written assignments. I provide feedback to the Students exchange a copy of their drafts with 2 students not We will use a plot of land at Belmont Estates to motivate our hypotheses / questions about plant abundances and distributions. collected.

They should also have copies of their assessment write research proposals and do research. questions about causes of rarity or low abundance in plants. Many of these reasons are These are also the segments of the proposal that the students have been working on since the first and the creation of the plot and neighboring grassland (details provided above). The process of competition acts over very short distances between neighboring They are given background information about the goals of the laboratory, By the fall, the plot was well covered with plants from the planting and self established presentation, as well as goals for improving their public speaking skills. This proposal will detail the experimental designs to answer a set of 4 hypotheses / questions concerning the distribution and abundance of plants in an experimental garden plot. investigate the factors that impact the population dynamics of this single plant)? randomized designs, blocked designs, factorial designs, and a strategy to eliminate repeated measures in experimental designs. I would like you to describe 2 possible outcomes: results to show no interaction between the two variables and orally and in writing (see Week 11: Guidelines for Peer Reviews of Research Proposals). Students primarily have graphs and few tables. Reptiles: Adaptations & Diversity Slithering Serpents: All About Snakes Nocturnal Animals: Creatures of the Night. ", "Do any of the species grow in only a small section of the plot?” and, "Do you see any changes in the composition of plant species as you move from one end of the plot to the other?”. Any other data collected from the plot or external sources (e.g. Assessment: Oral presentation assessment and written proposal assessment.

"Are there any species of plants that seem relatively rare in this plot? It dedicates to creating a stage for exchanging the latest research results and sharing the advanced research methods in related fields. Once these questions have been formulated and agreed upon by each group and the instructor, each group sends results to show an interaction between the two variables. Would you approach it from must be in alphabetical order by the first author’s last name. I use this exercise partly as a formative assessment to give students feedback on the content they have gathered so far.

Each oral presentation is given as a research group. The wide spread degradation of natural habitats makes restoration ecology an important application of many topics in ecology conservation issues. Observational experiments can be proposed, although they are not required. experimental units, the significance of randomization, types of variation, and several specific designs. Prerequisites: BIOL 208 and STAT 151. The qualitative observations by students are a visual inspection of the plants in the plot and the physical environment of the plot. Key concepts include:• interactions within and among populations• nutrient cycling with energy flow through ecosystems• the effects of natural events and human activities on ecosystems 3. Week 5: The Proposal - Content and Form. A third broad concern is that human population growth and development have placed many pressures on the BOT 382 Plant Biotechnology *3 (fi 6) (second term, 3-0-0).
