Globalization causes many things to happen. For the scientists in this study, globalization has increased the spread of invasive species. If scientists can predict the spread of invasive species, the spread may be slowed or stopped. The question the scientists in this study wanted to answer is: How can scientists better predict the spread of invasive species?

Thinking About Science

Sometimes scientists examine existing data in a new way to figure out a problem or understand what should be done next. They might also look at the way other scientists have done research in the past to see if trying a new way might provide more useful information. One way scientists do these things is to read, discuss, and observe what has already been done.

 

In this study, scientists wanted to better understand and predict the spread of invasive species. Invasive species are usually nonnative species that change the environment, the economy, or human health. To make better predictions about where invasive species will spread, the scientists looked at how scientists currently predict the spread of invasive species. After the scientists studied how predictions are currently made, they made suggestions for improving the method. Making more accurate predictions about the future will help scientists better understand the environment, manage ecosystems and the economy, and protect human health. No matter what they are studying, scientists always look for better ways to do their research.


Thinking About the Environment

The scientists in this study were concerned with the spread of invasive species and their impact on the natural environment. To understand the spread of invasive species, the scientists needed to study the problem at many different levels in the natural environment. In science, we call the different levels scales.

Studying invasive species in a local community would be an example of a small scale study. In a small scale study, scientists study the habitat immediately surrounding the plant or animal. Studying invasive species by State, region, or the whole world would be a much larger scale study. As the scale of a study gets larger, less detail is examined.
Environmental scientists sometimes focus on the larger scale to examine how large areas containing plants and animals interact with the land. Think of something you have studied in school that could be examined at several different scales.


What are Ecosystem Services?

Ecosystem services result in benefits that people receive from ecosystems. Ecosystem services are often put into four categories. These categories are (1) those that provide, (2) those that regulate, (3) those that support, and (4) those that help people culturally. Ecosystem services that provide, for example, include the products of trees. This is because trees provide food, wood products, and fuel. Ecosystem services that regulate include, for example, processes that help slow the spread of invasive species. Supporting ecosystem services refer to things like the continual cycling of carbon and nitrogen from Earth to the atmosphere and back. This is because these elements support life. Cultural services are provided by places for educational or recreational activities, such as streams for canoeing. For more information on these four categories, read the “Welcome” at the beginning of the Ecosystem Services journal.

 

In this research, the scientists wanted to do a better job of predicting the spread of invasive species. When invasive species spread to new areas, the plants and animals that naturally live there are affected and even die. The normal ecosystem services that these native plants and animals provide are then no longer available unless other organisms replace them.

Introduction

People can now travel to most places because transportation has greatly improved. Countries can easily trade with many different countries across the planet. This process is called globalization. Globalization causes many things to happen. For the scientists in this study, globalization has increased the spread of invasive species. With more people, animals, and plants moving back and forth between places, it is easier for invasive species to move from place to place. If scientists can predict the spread of invasive species, the spread may be slowed or stopped. The question the scientists in this study wanted to answer is: How can scientists better predict the spread of invasive species?

Method

The method scientists used to study this problem was interesting and fun. About 100 scientists met in New Mexico at a conference. The scientists met in small groups based on topics of interest. For example, some of the topics included hurricanes, sea level rise, and coastal wetlands. Each group of scientists decided to write papers about their own topic. Because the scientists lived all over the United States, they had to use technology to communicate with each other. The scientists communicated on the phone, in person, and through emails.

To answer their question, the scientists examined the research that had already been done on invasive species. The scientists examined the methods other scientists used to make predictions about the spread of these invasive species. When a particular example is studied, this is called a case study. An example of a case studied was the zebra mussel.

The zebra mussel invaded the Great Lakes and has moved into rivers surrounding the Great Lakes (figure 1).

Figure 1. The Great Lakes and the States that surround the Great Lakes. Do you live near the Great Lakes?

The zebra mussel affects the lakes’ ecosystem in many ways (figure 2). Zebra mussels change the environment by disrupting food webs and causing native mussels to die. To predict the movement of a plant or animal such as zebra mussels, scientists sometimes create models of what might happen. These models are built on computers, and they represent what might happen in real life. Models are used to make predictions about many different things. When you see a prediction of the path that rain, snow, or a hurricane might take in the future, you are looking at the results of a computer model.

The scientists looked at many predictions and the computer models upon which they were based. Then, they worked together to evaluate which predictions were the most successful.

Findings

Five scientists worked together to develop a paper on invasive species. The scientists had different views on the spread of invasive species. The scientists had to have many discussions to come to an agreement about their different points of view. Each scientist had to think carefully and consider the ideas of the other scientists.

The paper the scientists wrote about predicting the spread of invasive species combines different ideas about invasive species into one story. Once the invasive species paper had been written, the paper was passed back and forth between all the scientists for editing and comments.

After the scientists agreed with what was written, the paper was sent out for peer
review. Peer review is a process involving others who are considered an equal in knowledge or skill. In this case, other scientists read the paper and provided comments and suggestions. These other scientists had not been involved with the project before then, but they knew about invasive species. After this review, the paper was published in a journal.

In their paper, the scientists discussed their findings about predicting the spread of invasive species. The scientists found that some models of the spread of invasive species were more successful at prediction than others. They were more successful if they examined larger geographic scales. The scientists recommended that in the future, scientists should examine the spread of invasive species at all geographic scales.

Discussion

The scientists who wrote this article on invasive species benefited from examining the issue of invasive species from different perspectives. Science benefits from lively discussion with different points of view on the same topic. Progress is made in science when different points of view can be combined into one story. The scientists had different ideas but were able to come to an agreement on how the spread of invasive species should be predicted. The efforts of these scientists allowed the study of ecosystem services and invasive species to advance.

 

The importance of studying invasive species at different geographical scales was highlighted in the scientists’ paper. Understanding the impact of invasive species on the local level as well as the impact at a larger geographical scale is important. Examining the possible impact at the larger geographical scale will help scientists make better predictions. The scientists suggested that this larger geographical study needs to be a coordinated effort among scientists across the globe.

The Next Generation Science Standards (NGSS) are a set of K-12 science education standards emphasizing inquiry-based learning, real-world applications, and integrating engineering practices, aiming to deepen understanding of science while promoting critical thinking and problem-solving skills.
  • ESS3.C-M1
    Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things.
  • ETS1.B-M1
    A solution needs to be tested, and then modified on the basis of the test results, in order to improve it.
  • ETS1.B-M2
    There are systematic processes for evaluating solutions with respect to how well they meet criteria and constraints of a problem.
  • ETS1.B-M3
    Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors.
  • ETS1.B-M4
    Models of all kinds are important for testing solutions.
  • ETS1.C-M1
    Although one design may not perform the best across all tests, identifying the characteristics of the design that performed the best in each test can provide useful information for the redesign process—that is, some of the characteristics may be incorporated into the new design.
  • ETS1.C-M2
    The iterative process of testing the most promising solutions and modifying what is proposed on the basis of the test results leads to greater refinement and ultimately to an optimal solution.
  • LS2.A-M1
    Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.
  • LS2.A-M2
    In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction.
  • LS2.A-M3
    Growth of organisms and population increases are limited by access to resources.
  • LS2.A-M4
    Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.
  • LS2.B-M1
    Food webs are models that demonstrate how matter and energy are transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
  • LS2.C-M1
    Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
  • LS2.C-M2
    Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health.
  • LS4.D-M1
    Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.
The Common Core Standards are educational benchmarks in the United States that outline clear expectations for what students should know and be able to do in English language arts and mathematics from kindergarten through 12th grade, aiming to ensure consistency and coherence in education nationwide.

What Is a Natural Inquirer Journal?

Three Natural Inquirer journal covers with NI bee

 

A Natural Inquirer journal is a collection of 4-8 articles on a related science topic. Journals are written for a middle school audience, but they can also be adapted for both high school students and advanced upper elementary students. Some journals are particularly suited to high school students; you can find our grade level recommendations in the tags on the product page or by filtering journals by grade level.

Journals include:

  • Four to eight articles based on published, peer-reviewed research papers; the articles keep the research paper format (see more below) but are written in language students can understand.
  • A FACTivity for each article, which is an activity to complete after reading the article. The FACTivity helps reinforce major science concepts from the article. These activities are designed to be easy to implement, with few material requirements and options for adapting them for your audience or available resources. Some articles in a journal may have two FACTivities.
  • A short “Welcome to the journal” article about key background information and science concepts that unify the articles included in the journal
  • A glossary of new terms for each article and the introductory materials.
  • A list of related Natural Inquirer publications for each article as well as outside references.
  • Standards correlations, including Next Generation Science Standards, addressed in the articles and the FACTivities.

Journals may also include additional essays (called spotlights), other activities (like crossword puzzles or vocabulary challenges), and more.

Reading Modes

Journals are available in three different formats:

  • Hard copies can be ordered from the website and shipped, all free of charge.
  • PDF versions of the printed journal can be downloaded free on the website. The PDF version directly replicates the content and layout of the printed version. You can also download individual articles as pdfs.
  • The “Read Distraction Free” option allows the individual articles to open in their own window, without the rest of the website being visible. These articles can be found under the “Articles” tab. This version allows readers to scroll to particular sections of the article using the sidebar menu on the left side of the screen. This version also has interactive Reflection Sections and Number Crunches. Students can enter their answers, submit them, and then receive the correct answers to double-check their work. Submitted answers are not saved on the website and will disappear once the window is closed.

  4. Introduction

    This section begins the scientific article format. Much like the published, peer-reviewed study this article is based on, the introduction provides background information for the study – what is currently known and what remains unknown. The introduction culminates in the question(s) the study hopes to answer.

    The introduction is also the first section with a Reflection Section. This section includes two or three questions to help kids reflect on what they’ve just learned in the Introduction. If they are using the online distraction-free reading mode, they can answer these questions directly on the website.

    Use this section to:

    • Review important background information that kids need to understand the study
    • Connect the study to the concepts addressed in the Thinking About Science and Thinking About the Environment sections
    • Understand research questions and hypotheses, including generating their own hypotheses given what they already know

    Next Generation Science Standards applications:

    • Life Science and some Earth Science Disciplinary Core Ideas (depending on topic)
    • Most Crosscutting Concepts (depending on topic)

  5. Methods

    This section is the nuts and bolts of the study design – the who, what, when, where, why, and how of the research. Contained within the Methods section are usually maps of the study location or the set-up of study plots, as well as details about what data was collected and how.

    The Methods section also ends with a Reflection Section – two or three questions to help students think through what they just read. These questions are interactive on the distraction-free reading mode.

    Use this section to:

    • Show students how experiments and studies are designed and carried out
    • Explore sampling methods and randomization
    • Introduce various data collection tools (e.g. camera traps, surveys, insect collection tools, weather stations, etc.)
    • Explain bias and how studies are designed to remove bias
    • Help students gain experience with map reading

    Next Generation Science Standards applications:

    • Life Science and some Earth Science Disciplinary Core Ideas (depending on topic)
    • Most Crosscutting Concepts (depending on topic)

    Note that specific standards for this particular monograph are linked on this educator guide tab.

    Other resources:

    Many Methods and Findings sections contain Number Crunches, which are simple math exercises designed to help students interact with the data from the study.

  6. Findings

    This section summarizes the data collected during the study. The Findings section usually includes data tables or graphs and highlights the significant data points from the study. This section often mentions statistical analysis or the use of computer programs to model or analyze the data, though these methods are only discussed generally.

    The Findings section also ends with a Reflection Section – two or three questions to help students think through what they just read. These questions are interactive on the distraction-free reading mode.

    Use this section to:

    • Have students practice reading and interpreting graphs and tables
    • Compare results between variables and controls
    • Explain the concept of statistical significance
    • Discuss how no data or negative results still provide valuable information

  7. Discussion

    This section concludes each article. In it, we summarize the main findings of the scientists’ study. Additionally, we present the scientists’ ideas about the limitations of their study, the big-picture impacts of their research, and the scientists’ plans for future study or action.

    The Discussion section ends with a Reflection Section – two or three questions to help students think through what they just read, especially general take-aways from the study. These questions are interactive on the distraction-free reading mode.

    Use this section to:

    • Discuss what conclusions can and cannot be drawn from the available data
    • Explain the difference between correlation and causation
    • Explore study limitations and opportunities for further study
    • Brainstorm ways the study findings could be applied to real-world situations

Additional Resources on the Website

A screenshot of the product tabs for an NI monographOn the website, we pair each journal with a variety of other resources, as well. Use the tabs on the product page to browse through the following:

  • Related activities, including the FACTivity for each article
  • An “About” essay that gives some larger context for the research the scientists conducted or more information about the science topic from the journal
  • A glossary of all boldfaced terms from the journal
  • A “Scientists and Collaborators” page that lists the people involved in the studies in the journal; click on a researcher to reach their bio page and see what other articles they might be featured in
  • A “Related Content” page that lists both Natural Inquirer resources about similar topics and also outside reference materials

Article Selection and Review

Natural Inquirer partners with the USDA Forest Service, so we source research studies by Forest Service scientists that have been peer-reviewed and published in reputable journals. Some of our articles have also been created in collaboration with scientists from other Federal agencies, such as U.S. Geological Survey and the United Nations Food and Agriculture Organization, universities, and other non-profits.

All journal articles are reviewed by scientists who conducted the original research study to verify scientific accuracy. Journals are also reviewed by student editorial review boards of middle or high school students before publication. Additionally, all journals are reviewed by the Forest Service and the U.S. Department of Agriculture before publication.

A screenshot of the citation for "Lights, Camera, Tracks"Every journal article includes a citation of its source study. Many educators pair the original research paper with our article to help more advanced students learn how to read formal research papers. The journal article then serves as adapted primary literature, bridging the two articles.

  • U.S. Geological Survey: Zebra Mussel Information Page

    The zebra mussel is a small shellfish named for the striped pattern of its shell. However, color patterns can vary to the point of having only dark or light colored shells with no stripes. This mussel is typically found attached to objects, surfaces, or other mussels by threads extending from underneath the shells.
