Yahia Fares University– Medea Faculty of Natural Sciences and life Ecology and Environment Techniques of Communication and Expression Presented by : Mehri.L 2023/2024  Introduction Communication ,which comes from the Latin word "communicare,"is a learned skill,it has been defined as the act of giving, receiving or exchanging informations, ideas and opinions so that the message is completely understood by both parties.fig1.1 communication takes various forms :  verbal communication : it involves the use of spoken words to convey message ;example :phone calls, speeches discussions  non- verbal communication : it relies on gestures, facial expressions eye contact posture  written communication : is the exchange of information, ideas, or messages through written language in the form of letters, emails, notes, and more.  In this course we will focus on writing communication specifically scientific writing. 1.scientific research it is a systematic process of gathering, analyzing, and interpreting data to answer a question or solve a problem. The goal is to gain new knowledge, improve understanding of existing phenomena, or develop new tools, products, or processes. 1.1 Purpose of Scientific Research  Helps us understand the world better.  Allows us to solve practical problems. 1.2Types of Scientific Research 1. 2.1Basic Research: Aims to expand knowledge without a specific application in mind. Example: Studying how plants grow in different environments. 1.2.2 Applied Research: Focuses on solving specific, practical problems. Example: Developing a new vaccine for a virus. 1.3Research methodology Research Process in these major steps: 1. Selection of a research topic ; 2. Definition of a research problem ; 3. Research design ; 4. Review the literature and reference collection; 5. Collecting the data (experiments); 6. Data analysis ; 7. Interpretation and analysis of result ; 8. Report Conclusions; 1.4 types of scientific literature. primary literature: are authored by researchers, contains original research data. original articles /case reports / technical notes secondary literature : When other writers summarize or review the theories and results of original scientific research, their publications are known as Secondary Literature. Review articles /books/ textbooks and manuals. 2.Writing Writing is the process of using symbols, such as letters and punctuation, to communicate thoughts and ideas. It involves organizing language into words, sentences, and paragraphs to convey information, tell stories and express emotions. Writing can take many forms, including creative writing, academic essays, business reports, journalism, and more. It serves as a means of recording, sharing, and preserving knowledge and personal expression. 3.Scientific text A scientific text is a form of writing that communicates research findings, theories, analyses, and scientific concepts. Its purpose is to present information in a clear, objective, and precise manner to inform, educate, or advance knowledge within a particular field. Scientific texts are characterized by structured formats (such as research papers, articles, and reports), a formal tone, and the use of specialized vocabulary. They often include data, citations, and references to other scientific work to support their claims and ensure credibility. 3.1 Types of scientific texts Scientific texts can be categorized into several types based on their purpose, audience, and content. Here are some common types: 1. Research Articles: These are detailed studies reporting origin² &-+al research findings. They usually include sections like introduction, methods, results, and discussion. 2. Review Articles: These summarize and synthesize existing research on a particular topic, providing a comprehensive overview of current knowledge. 3. Conference Papers: Presented at scientific conferences, these texts typically summarize preliminary research findings and facilitate discussion among researchers. 4. Theses and Dissertations: These are extensive research documents submitted as part of a graduate or doctoral program, detailing original research and its significance. 5. Technical Reports: Often produced by government agencies or research institutions, these documents present research findings and technical information on specific projects. 6. Case Studies: These focus on a specific instance or case within a field, providing in-depth analysis and insights. 7. Editorials and Commentaries: These reflect the author's opinion on current issues in the field, often discussing the implications of recent research. 8. Books and Textbooks: Comprehensive works that cover broader topics in detail, often used as educational resources. 9. Popular Science Articles: Written for a general audience, these articles aim to explain scientific concepts in an accessible manner. 10. Datasets and Supplementary Materials: These include raw data, statistical analyses, or additional materials that support research findings. Each type serves a different function within the scientific community, contributing to the dissemination and advancement of knowledge 3.2 Characteristics of scientific text Scientific texts have several characteristics that set them apart from other forms of writing. Here are some key features: 1. Objective Tone: Scientific writing aims to present information without bias. It avoids emotional language and subjective opinions. 2. Precise Language: The use of clear and specific terminology is essential. Scientific texts often employ jargon and technical terms relevant to the field to ensure accurate communication. 3. Structured Format: Many scientific texts follow a structured format, such as IMRaD (Introduction, Methods, Results, and Discussion) in research papers, which helps organize information logically. 4. Evidence-Based: Claims and conclusions are supported by empirical evidence, data, and research findings. References to previous studies are common. 5. Clarity :The writing is direct and straightforward, avoiding unnecessary complexity. Sentences are typically shorter, and paragraphs are focused on single ideas. 6. Use of Visuals: Graphs, charts, and tables are frequently used to present data visually, making complex information easier to understand. 7. Citations and References: Proper attribution to sources is crucial. Scientific texts often include citations and bibliographies to acknowledge the work of others and provide a context for the research. 8. Logical Argumentation: The text develops a clear argument or hypothesis, systematically presenting evidence and reasoning to support conclusions. 9. Replicability: Methods and procedures are described in sufficient detail to allow others to replicate the study or experiment. These characteristics help ensure that scientific communication is clear, credible, and effective for disseminating knowledge. 3.3Structure of a scientific text The structure of a scientific text typically follows a specific format to effectively communicate research findings. Here’s a common structure: 1. Title: A concise statement that reflects the main topic or findings of the research. 2. Abstract: A brief summary (usually 150-250 words) that outlines the objectives, methods, results, and conclusions of the study. 3. Introduction: This section introduces the topic, presents the background information, and states the research question or hypothesis. It explains the significance of the research and provides context. 4. Methods (or Methodology): A detailed description of how the research was conducted. This includes information on the study design, materials used, procedures followed, and data analysis methods. 5. Results: This section presents the findings of the study, often using tables, graphs, and figures to summarize data. It is focused on reporting results without interpretation. 6. Discussion: Here, the implications of the results are explored. The authors interpret the findings, compare them with existing literature, discuss limitations, and suggest future research directions. 7. Conclusion: A summary of the main findings and their significance, often highlighting the contributions of the study to the field. 8. References: A list of all the sources cited in the text, formatted according to a specific citation style (e.g., APA, MLA, Chicago) 3.4How to read and analyse a scientific text Steps for Reading and Analyzing a Scientific Text 1.

II Terminology Definition of Terminology: Terminology is the collection of specific words and phrases used to describe concepts or things in a particular subject or field. These terms help people in that fieldto communicate clearly and accurately. In general, terminology involves:  The collection of terms that are used in a specific subject, profession, or discipline.  The meaning of each term in that context.  The standardized use of these terms to ensure clarity and prevent misunderstandings. Scientific terminology : is the unique language of science, made up of precise words and terms that help explain the complex systems, processes, and discoveries within a particular field. Scientific terminology is the glue that holds knowledge together, ensuring that when a scientist says something, everyone with the right background knows exactly what they mean. It transforms ambiguity into clarity, turning complex ideas into clear concepts that can be universally understood and tested. Introduction to Ecological Terminology Definition: Ecological terminology refers to the set of specialized terms and concepts used to describe the interactions between living organisms (biotic) and their environment (abiotic), as well as the ecological processes that govern them. These terms help structure and make comprehensible the complexity of ecosystems and natural dynamics. Role of Terminology:  Scientific Precision: Terminology allows for precise and clear communication, which is essential for understanding ecological phenomena.  Uniformity: It promotes a common understanding of concepts among researchers, students, and environmental professionals worldwide.  Analysis: Terminology is fundamental for analyzing ecological data.  Interdisciplinary Communication: Ecology is an interdisciplinary science that draws from biology, chemistry, physics, and other fields, making shared terminology important. 2. The Importance of Ecological Terminology 2.1. Facilitating Understanding of Ecological Processes: Ecological terms help describe the complex interactions between organisms (e.g., predation, competition) and environmental processes (e.g., biogeochemical cycles). For example:  Competition: Interaction between individuals of the same or different species for limited resources (intraspecific( fig1)and interspecific competition(fig2)).  Predation: A relationship in which one organism (predator) captures and consumes another organism (prey). Fig1 Fig2  Fig3 2.2. Structuring Knowledge: Terminology helps organize knowledge into distinct but interconnected categories, such as:  Levels of Ecological Organization: Individual, population, community, ecosystem, biosphere.  Types of Interactions: Mutualism, commensalism, parasitism, etc. 2.3. Promoting Scientific Communication and Information Exchange. 3. Definitions of Key Ecological Terms Ecological terms can be divided based on several key factors that help categorize the different aspects of ecology. These factors include : Organizational Levels, Types of Interactions,. Environmental Concepts, Trophic Levels (Feeding Relationships), Energy Flow and Nutrient Cycling, Disturbances and Succession, Adaptations and Evolution 3.1. Levels of Ecological Organization:  Individual: A single living organism, whether a plant, animal, or microorganism.  Population: A group of individuals of the same species living in a specific geographic area and capable of interbreeding.  Community: The collection of populations of different species living in a given area and interacting with one another.  Ecosystem: A system made up of a community of organisms and their abiotic environment (soil, air, water, etc.) interacting as a whole.  Biosphere: The sum of all ecosystems on Earth where life exists. 3.2. Ecological Interactions:  Predation: An interaction in which one organism (the predator) hunts and consumes another organism (the prey).   Competition: When two or more individuals or species compete for the same limited resources.  Mutualism: A relationship beneficial to both partners (e.g., bee pollination).  Commensalism: A relationship where one species benefits without harming the other.  Parasitism: A relationship in which one organism (the parasite) benefits at the expense of the host. 3.3. Key Ecological Concepts:  Ecological Niche: The functional role of a species within an ecosystem, including its feeding, behaviors, and interactions.  Habitat: The physical environment where a species lives.  Biodiversity: The variety of life forms in an ecosystem, including species diversity, genetic diversity, and ecosystem diversity.  Ecological Succession: The gradual process of change in the structure of an ecological community over time. 3.4. Environmental Concepts:  Abiotic Factors: Non-living components of the environment (e.g., temperature, light, soil, water).  Biotic Factors: Living components of the environment, including organisms and their interactions. 3.5. Biogeochemical Cycles:  Carbon Cycle: The movement of carbon through the atmosphere, oceans, and terrestrial ecosystems.  Nitrogen Cycle: The process by which nitrogen is transformed in the environment, including its fixation, assimilation by plants, and return to the soil. 4. Applications of Ecological Terminology Research and Modeling:  Ecological terminology helps scientists create accurate models, analyze data, and describe results clearly, aiding in environmental studies. Conservation and Management:  Clear terminology is crucial for developing strategies to protect ecosystems, manage resources, and conserve biodiversity. Environmental Policy:  Ecological terms are essential in shaping policies and regulations to address environmental issues like climate change, pollution, and habitat destruction. Education and Public Awareness:  Ecological terminology helps in teaching and raising awareness about environmental issues, making complex ecological concepts easier to understand.  Ecosystem Monitoring: Terminology helps describe and assess the health of ecosystems by defining key indicators like biodiversity, water quality, and pollution levels. 5. Conclusion: The Importance of Mastering Ecological Terminology Ecological terminology is not just a set of technical words; it reflects deep concepts that help us understand, describe, and analyze the interactions between organisms and their environment. Mastering this terminology is essential for ecologists and environmental professionals, as it allows for clear and rigorous communication of ideas, observations, and scientific results. Furthermore, it is vital for applying ecological concepts to practical problems, such as biodiversity management, combating climate change, and ecosystem restoration.

Biotic and Abiotic Factors  Biotic Factors: The living components of an ecosystem (e.g., plants, animals, fungi).  Abiotic Factors: The non-living components of an ecosystem (e.g., sunlight, water, temperature, soil). 8. Biomes Large ecological areas on Earth with distinct climates and specific plant and animal communities. Examples include deserts, forests, grasslands, and tundras. 13. Symbiosis A close and long-term interaction between two different species. Types include: Mutualism: Both species benefit. Commensalism: One species benefits while the other is unaffected. Parasitism: One species benefits at the expense of the other. 14. Eutrophication The process by which water bodies become enriched with nutrients (often from runoff), leading to excessive growth of algae and depletion of oxygen. 15. Succession The gradual process by which ecosystems change and develop over time following a disturbance or the creation of new habitats. 16. Carrying Capacity The maximum population size that an environment can sustainably support without degrading the ecosystem. 17. Biodiversity The variety of life in a particular habitat or ecosystem, including the diversity of species, genetic diversity within species, and diversity of ecosystems themselves. Anthropogenic  Definition: Refers to changes in the environment that are caused by human activity, such as deforestation, pollution, or climate change.  Example: Climate change is primarily caused by anthropogenic activities, such as burning fossil fuels 18. Climate Change Long-term changes in temperature and weather patterns on Earth, largely driven by human activities such as fossil fuel burning and deforestation Climate vs. Weather  Climate: The long-term average of weather conditions in a region over a long period (decades or centuries).  Weather: The short-term atmospheric conditions, including temperature, precipitation, and wind, in a specific place at a particular time.  Example: Climate refers to a tropical rainforest's year-round warmth and rainfall, while weather refers to a rainy day in that same rainforest. Food Chain and Food Web  Food Chain: A linear sequence of organisms through which nutrients and energy pass, starting from producers to primary consumers and up to higher trophic levels.   Food Web: A more complex network of interconnected food chains, showing how energy flows through an ecosystem.  Example: Grass → Rabbit → Fox (Food Chain)  Example: Grass → Rabbit → Fox → Eagle (Food Web) Trophic Levels  Definition: The hierarchical levels in an ecosystem, based on the organisms' source of energy (e.g., producers, primary consumers, secondary consumers, etc.).  Example: A food chain has producers at the first trophic level, herbivores at the second, and carnivores at the third. Producer (Autotroph)  Definition: Organisms that produce their own food through photosynthesis or chemosynthesis, typically plants, algae, and some bacteria.  Example: Plants in a forest that convert sunlight into energy. Consumer (Heterotroph)  Definition: Organisms that consume other organisms for energy, including herbivores, carnivores, omnivores, and decomposers.  Example: A lion is a carnivorous consumer that feeds on herbivores like zebras. Invasive Species  Definition: Non-native species that, when introduced to a new environment, cause harm to local ecosystems by disrupting existing biodiversity and food webs.  Example: The zebra mussel is an invasive species in North America that disrupts local aquatic ecosystems. Biogeochemical Cycles  Definition: The circulation of essential elements through the environment in different forms, including the water cycle, carbon cycle, nitrogen cycle, and phosphorus cycle.  Example: The carbon cycle moves carbon between the atmosphere, oceans, and living organisms. Primary and Secondary Succession   Primary Succession: The process of ecological change that occurs in an area that has not been previously inhabited or disturbed (e.g., after a volcanic eruption).  Secondary Succession: The process of ecological recovery that takes place in an area where a disturbance has occurred but soil remains (e.g., after a forest fire).  Example: Primary succession could occur on bare rock, while secondary succession might occur in a field abandoned by humans. Carrying Capacity  Definition: The maximum number of individuals of a species that an environment can support sustainably, given the resources available. Decomposer  Definition: Organisms, typically fungi and bacteria, that break down dead or decaying organisms, recycling nutrients back into the ecosystem.  Example: Fungi decomposing fallen leaves in a forest What is a Scientific Report?  Definition: "A scientific report is a detailed document that communicates the findings of an experiment or research study in a structured and systematic way. It allows researchers to present their methods, data, and conclusions in a manner that can be understood, evaluated, and reproduced by others in the scientific community. In ecology, these reports often focus on understanding environmental processes, species behavior, or ecosystem dynamics, and they aim to contribute knowledge that helps in solving ecological challenges. A good scientific report is clear, concise, and objective, ensuring that every claim is supported by evidence.  Purpose: The purpose of a scientific report is to share the results of an ecological study or experiment with the scientific community in a structured, transparent way. It allows researchers to communicate their findings, explain their methods, and provide evidence that supports their conclusions. By doing so, it enables others to verify, critique, and build upon the research, advancing knowledge in the field. In ecology, the goal is often to contribute to a deeper understanding of environmental systems, biological processes, and conservation issues.   Example: Suppose you conducted an experiment on the effects of light exposure on plant growth. Your scientific report would summarize your findings, methods, results, and what you learned about plant growth and light exposure. Step 2: Basic Structure of a Scientific Report Scientific reports typically follow a standard structure: 1. Title oThe title that reflect the main topic of the study. oExample: “Effects of Light Exposure on the Growth Rate of Tomato Plants.” 2. Abstract o The abstract is a brief summary of the entire report, including purpose, methods, results, and conclusion. o Example Abstract: “This study investigated the effects of different light intensities on the growth of tomato plants. Results indicated that increased light exposure significantly improved growth rates, suggesting that light is a key factor in plant development.” 3. Introduction o The introduction provides background information, explains why the study is important, and states the research question or hypothesis. o Example Introduction: “Plants rely on light for photosynthesis, which is essential for growth. This study examines how varying light intensities impact tomato plant growth, aiming to determine optimal lighting conditions.” 4. Methods o This section describes the procedures, materials, and conditions of the study.. o Example Methods: “Five groups of tomato plants were exposed to different light intensities: low (100 lux), medium (500 lux), and high (1000 lux) for six hours per day. Growth was measured weekly over six weeks.” 5. Results o The results section presents the findings with data, using tables, charts, or graphs as needed, without any interpretation. o Example Results: “Plants in the high light group showed an average growth rate of 2 cm per week, compared to 1 cm in the medium group and 0.5 cm in the low group.” 6. Discussion o Here, interpret the results, discuss any unexpected outcomes, and explain the significance of the findings. o Example Discussion: “The data supports the hypothesis that higher light intensity promotes faster growth. These findings align with previous research  on the importance of light for photosynthesis. However, additional studies could examine whether excessive light might eventually hinder growth.” 7. Conclusion o The conclusion summarizes the main findings, their implications, and any recommendations for future research. o Example Conclusion: “High light exposure positively affects tomato plant growth, suggesting it as an effective strategy for improving crop yield. Further studies could explore the upper limits of light exposure for optimal growth.” 8. References o List all sources used in your research. o Example Reference: Smith, J. (2021). “Photosynthesis and Light Intensity.” Journal of Plant Biology, 45(3), 201-210. Step 3: Tips for Writing Each Section  Be Clear and Concise: Scientific reports should be direct and avoid unnecessary details.  Use Past Tense: Since you’re reporting on completed work, most of the report (except for the hypothesis and any general statements) should be in the past tense.  Be Objective: Stick to the facts in the Results section. Save interpretations and opinions for the Discussion.  Make It Visual: If possible, use tables or graphs in the Results section to make your data easier to understand. Step 4: Example Activity  Activity: Give students a short sample experiment to work with. For example, “Measure the effect of water frequency on the growth of a small plant.” Ask them to: 1. Write a mock Title, Introduction, and Hypothesis. 2. Outline a basic Method, suggest expected Results, and draft a brief Discussion and Conclusion.  Discussion: Afterward, review their reports together, comparing approaches and clarifying any questions. Citing Sources and Avoiding Plagiarism Why Cite?: Citations give credit to the original authors. They also help others find the same information. How to Cite: Follow the format your teacher or guide prefers (e.g., APA, MLA). Definition and purpose of bibliographic research. "Bibliographic research is the process of identifying, locating, and analyzing existing information sources to gather comprehensive knowledge on a particular topic. This type of research involves reviewing academic books, journal articles, reports, and other credible resources to understand what has already been studied, to identify knowledge gaps, and to support new research efforts. It is a foundational skill in academia that allows researchers to build on existing knowledge and make informed contributions to their field. Example: Imagine you’re studying why certain plants grow better in one type of soil than another. Bibliographic research would involve looking up studies, articles, or books that explain soil types, plant growth factors, and similar studies.  Why It’s Important: In science, we learn from what other scientists have discovered. Good research helps us use trustworthy information. It’s like having a map: without it, you might waste time going in the wrong direction. In academic work, bibliographic research allows students and researchers to explore what’s already known, identify gaps in knowledge, and provide a strong foundation for new investigations. Types of academic sources (primary, secondary, review articles): (Where to Find Information) Academic sources are publications that present well-researched, credible, and reliable information created by experts in a specific field. These sources include articles, books from academic publishers, conference papers, and research reports.  Primary Sources: These are original studies and experiments. They provide direct evidence or results. o Example: A journal article where scientists explain their experiment on soil and plant growth.  Secondary Sources: These summarize or discuss primary sources.  o Example: A review article summarizing multiple studies on soil types and plant health.  Research Tools and Resources (Places to Find Sources) o Academic Databases: Websites like Google Scholar, PubMed, or ScienceDirect have reliable scientific articles. o Library Catalogs: University libraries often give students access to books and scientific journals.  Activity: Let students try a quick search on Google Scholar. Look up "effects of soil types on plant growth." ( Overview of academic journals, conference papers, and reports in ecology). Defining Research Topics and Keywords  Objective: Learn how to narrow down a research topic and use effective keywords. How to Define a Research Topic and Keywords ?  Choosing a Topic: Start with a specific question. For example, “How does soil type affect plant growth?”  Finding Keywords: Think of the important words in your question. Here, the main words might be: o “Soil type” o “Plant growth”   Using Synonyms and Variations: Sometimes, articles use different words for the same idea. o Examples of Variations:  “Soil quality” instead of “soil type”  “Plant development” instead of “plant growth”  Activity: Ask students to list keywords for a question of their choice, like “How do animals adapt to climate change Evaluating Sources  Why Evaluate?: Not all sources are reliable. We want high-quality, trustworthy studies.  How to Check Quality: o Author: Is the author a scientist or expert? o Journal: Was it published in a reputable journal? o Date: Is it recent? Newer studies are often more accurate. o Peer Review: Has it been reviewed by other scientists?  Example: Compare an article from a well-known scientific journal vs. a random website. Which one would you trust? Organizing a Literature Review  Purpose: A literature review summarizes what you learned from other sources.  Organize by Theme: Group related ideas together, like “different soil types,” “effects on roots,” or “growth rate in plants.”  Identify Gaps: Point out what you didn’t find answers to. This could guide future research. Citing Sources and Avoiding Plagiarism Why Cite?: Citations give credit to the original authors. They also help others find the same information. How to Cite: Follow the format your teacher or guide prefers (e.g., APA, MLA).
