What Kinds of Scientists Did This Research?

Ecologist: A scientist who studies the relationship between living things and the environment.

Forester: A scientist who studies forests, or is skilled in planting, managing, and caring for trees.

Geographic Information Specialist (GIS) and Research Technician: A scientist who studies the relationship between geographic data, maps, and various other data sets.

Thinking About Science

Scientists often address problems that need a practical and inexpensive solution. In this research study, the scientists looked for a way to help with forest restoration. Forest restoration is bringing a forest back to its natural state after a disturbance like tree harvesting or fire. To study this question, the scientists developed an experimental design to test different solutions. An experimental design is a procedure to investigate a possible relationship between variables.

The scientists examined how a forest patch responded to four different types of treatment options. A forest patch is an area of forest identified by the scientists that could be treated to help restore the tropical forest. The scientists used the results of their experiment to make recommendations about how to restore certain forest areas.


Thinking About the Environment

Located in the tropics of the Pacific Ocean, the Pacific Islands are unique (figure 1). Because these islands are located close to the equator, their climate is warm all year. In this research, the scientists wanted to determine the best method for restoring tropical forests. Tropical forests are home to a wide variety of plant and animal life.

Figure 1. The tropics is an area (band of latitude) surrounding the equator between the Tropic of Cancer and the Tropic of Capricorn.

In this study, the area the researchers were studying is in the Republic of Palau (pǝ laů). The Republic of Palau is in the western Pacific Ocean and is a part of a geographic region known as Micronesia (figure 2). The Republic of Palau consists of 340 coral and volcanic islands. It is considered a biodiversity hotspot as it is part of the larger Micronesia-Polynesia hotspot (see sidebar below).

In this study, scientists observed the number of birds that visited forest patches. Some of the endemic birds that were found visiting the patches were the dusky white-eye, the Micronesian starling, the Palau cicadabird (sǝ kā dǝ bǝrd), the Palau fruit dove, and the morningbird (figure 3). With all the biodiversity in Palau, it is important to maintain good habitats for these plants and animals so that they can continue to flourish.

What Is a Biodiversity Hotspot?

A biodiversity hotspot is defined as a location that has at least 1,500 endemic vascular plant species and has lost at least 70 percent of its primary native vegetation. While Palau by itself does not fit the definition, it is a part of the larger Micronesia-Polynesia hotspot.


Introduction

Babeldaob (bä bǝl daůb) is the largest island of the Republic of Palau (figure 4). Babeldaob contains one of the largest intact areas of native tropical lowland rainforest in the tropical Pacific. It is known for its great abundance of ecological diversity and is home to Lake Ngardok (ǝ gär däk) Nature Reserve. The reserve covers 650 hectares (ha) of land and contains Lake Ngardok (figure 5).

Lake Ngardok is the largest freshwater lake in Micronesia and is considered a local hotspot for endemic plant and animal species (figure 6). Endemic species are native to a specific area and found nowhere else on Earth. Endemic species are often endangered and are an important component of biological diversity.

Parts of the Lake Ngardok Nature Reserve were cleared for agriculture in the early 1900s and then abandoned after World War II ended in 1945. Vegetation that grew in this area was periodically managed with fire until the reserve was created in 1997. The management plan for the reserve called for restoring the soils and forest. Attempts were made to do this by planting Acacia auriculiformis (ǝ kā shǝ är ik yǝ lǝ fȯr mǝs), a nonnative tree that was meant to help improve the quality of the soil (figure 7). However, this strategy failed because almost all the trees died or had stunted growth. Therefore, the scientists in this study were interested in figuring out what kind of treatment would lead to the best outcomes for the restoration of native forest here.

Methods

The scientists identified 32 forest patches (figure 8). The patches varied in size from 4 to 275 square meters (m^2). The scientists applied four different treatments for forest restoration (table 1) and monitored these patches for 3 years. Each of the treatments were low cost and easy to implement.

A table showing the different types of forest patch treatments

Table 1. The scientists examined four different treatments for forest restoration: interior patch fertilization, outer patch perimeter mulching, outer patch perimeter trimming, and planting native tree seedlings.

The scientists examined six ecological indicators to determine the effectiveness of the patch treatments (table 2). Ecological indicators enable scientists to gauge how the environment is responding to a certain treatment or a changing condition.

Table 2. The scientists examined data regarding six ecological indicators.

The scientists recorded a variety of data including the number of patch visits by birds and flying foxes, the number of flowering and fruiting plants, and the number and diversity of seedlings as well as the data for the six ecological indicators (figures 9 and 10).

Findings

The scientists found that the diversity of tree species, the height of the tallest patch tree, and basal area of the trees all increased with the size of the patch. The scientists also found that the diversity of bird species increased with the size of the patch.

What Is Basal Area?

Basal area of a tree is defined as the cross-sectional area (in square meters or square feet) of a single tree at breast height, or 1.37 meters (4.5 feet) above ground.

The diameter of a tree at 1.37 meters above the ground is called diameter at breast height (or DBH).

The application of fertilizer helped accelerate patch expansion. Four years after establishing the forest patch sites, the fertilized patches had expanded about five times more than nonfertilized forest patches. Fertilizer use also increased flower, fruit, and new tree leaf production. In fertilized patches, more tree species per patch flowered, fruited, and had new leaves than the nonfertilized patches. Fertilizer also helped increase the growth of naturally occurring saplings.

Fertilized forest patches had an increase in bird visitation. The three species that visited the most were dusky white-eye, Micronesian starling, and the Palau cicadabird. Eight species on the list are endemic to Palau (table 3). Additionally, the Palau flying fox visited only one patch but had far more flyovers than any other species in the study. A flyover occurs when an animal flies over but does not stop at the forest patch. These are important to forest restoration because birds and bats can disperse seeds during flyovers when they defecate or otherwise drop a seed. These seeds may then establish themselves and grow in that area.

Discussion

The scientists found that 6 of the top 10 patch visits were made by species that are endemic to Palau. Scientists believe that this may indicate that endemic species play an important role in how plant communities interact and restore landscapes. Scientists also found that fertilizer application had a positive effect on forest patch trees and that effect extended all the way to the exterior edge of the patches.

The scientists determined that small, periodic applications of fertilizer can increase the rate of forest patch expansion and lead to greater visitation by native or endemic birds. This small, periodic application of fertilizer also avoids potentially damaging nutrient runoff from fertilizers. Sometimes, too much fertilizer runoff going into waterways can cause problems for plants and animals. By limiting the amount of fertilizer used per application, this problem is reduced.

Standards addressed in this Article:

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-H1
    The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.
  • ESS3.C-H2
    Scientists and engineers can make major contributions by developing technologies that produce less pollution and waste and that preclude ecosystem degradation.
  • 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.
  • LS1.B-M3
    Plants reproduce in a variety of ways, sometimes depending on animal behavior and specialized features for reproduction.
  • LS1.B-M4
    Genetic factors as well as local conditions affect the growth of the adult plant.
  • LS2.A-H1
    Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from challenges such as predation, competition, and disease. Organisms would have the capacity to produce populations of great size were it not for the fact that environments and resources are finite. This fundamental tension affects the abundance (number of individuals) of species in any given ecosystem.
  • 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-M3
    Growth of organisms and population increases are limited by access to resources.
  • LS2.C-H1
    A complex set of interactions within an ecosystem can keep its numbers and types of organisms relatively constant over long periods of time under stable conditions. If a modest biological or physical disturbance to an ecosystem occurs, it may return to its more or less original status (i.e., the ecosystem is resilient), as opposed to becoming a very different ecosystem. Extreme fluctuations in conditions or the size of any population, however, can challenge the functioning of ecosystems in terms of resources and habitat availability.
  • LS2.C-H2
    Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species.
  • 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.C-H4
    Changes in the physical environment, whether naturally occurring or human induced, have thus contributed to the expansion of some species, the emergence of new distinct species as populations diverge under different conditions, and the decline–and sometimes the extinction–of some species.
  • LS4.C-H5
    Species become extinct because they can no longer survive and reproduce in their altered environment. If members cannot adjust to change that is too fast or drastic, the opportunity for the species’ evolution is lost.
  • LS4.D-H1
    Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction).
  • LS4.D-H2
    Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change. Thus, sustaining biodiversity so that ecosystem functioning and productivity are maintained is essential to supporting and enhancing life on Earth. Sustaining biodiversity also aids humanity by preserving landscapes of recreational or inspirational value.
  • 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.
  • Cite specific textual evidence to support analysis of science and technical texts.
  • By the end of grade 8, read and comprehend science/technical texts in the grades 6-8 text complexity band independently and proficiently.
  • Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.
  • Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
  • Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.
  • Analyze the structure an author uses to organize a text, including how the major sections contribute to the whole and to an understanding of the topic.
  • Analyze the author's purpose in providing an explanation, describing a procedure, or discussing an experiment in a text.
  • Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).
  • Distinguish among facts, reasoned judgment based on research findings, and speculation in a text.
  • Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.

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.

What's in a Natural Inquirer Article?

Here, we'll go into more detail about the parts of a Natural Inquirer article and give you some ideas about how they can be used.
  1. Meet the Scientists

    This section introduces the scientists (and others) who worked on the study. In their own words, they each share a memorable science experience, a favorite research project, or something they learned during the course of their education or research.

    Use this section to:

    • Introduce kids to the variety of people who work in science
    • Introduce kids to the variety of scientific fields and give brief descriptions of science-related jobs
    • Explore ways that people interact with science every day

  2. Thinking About Science

    This section briefly describes a concept about science or scientific research. This overview can touch on topics like

    • study type (longitudinal study, quantitative vs. qualitative data),
    • behaviors of scientists (conducting literature reviews, collaborating with other specialists, replicating earlier studies),
    • the practice of science (the scientific method, engineering design, data collection, randomization, controls and variables),
    • or other aspects of science (bias, correlation vs. causation).

    Use this section to:

    • Reinforce steps in the scientific method and the process of science
    • Encourage students to think about the practice of science and what it can and cannot tell us
    • Consider the many types of scientific study and what information each type can provide

    Next Generation Science Standards applications:

    • Science and Engineering Practices
    • Life 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:

    You can use key words to search for other or related scientific topics on our website (e.g. “longitudinal study,” “bias,” or “sampling”).

  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)

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

  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

    Next Generation Science Standards applications:

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

  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.
