Longleaf pine (Pinus palustris) once could be found from southeastern Virginia to eastern Texas. Longleaf pines are not usually killed by fire. Because these pines need open spaces to survive, fire is a good thing for longleaf pines. Over many years, much of the longleaf pine forests were cut for lumber.

Now, however, many people are concerned about longleaf pine forests. In many areas, these forests are being managed to help them survive and grow. Fire is a necessary part of this process. The scientists in this study were interested in what happens to arthropods after a fire. They developed a hypothesis about the importance of old logs lying on the forest floor to leaf-litter-dwelling arthropods. The scientists thought that, after a fire, arthropods living among leaf litter would move to the areas around old logs because they didn’t have other places to hide.

Thinking About Science

Before they do a study, scientists sometimes state a hypothesis. A hypothesis is a statement of an observation, usually about the relationship of one thing to another. A hypothesis can provide the basis for a scientific study, in which the observation is examined to determine if it is true or false.

 

Scientists usually state their hypothesis as what is called a null hypothesis. A null hypothesis states that there is no relationship between two or more variables being studied. After they do their study, scientists determine whether the null hypothesis is true or false. If it is false, it means a relationship appears to exist between two or more variables. Think of a time that you observed something about the relationship of two things. For example, if the sky is dark and cloudy, you might think it will rain. What would be the null hypothesis in this case?


Thinking About the Environment

Have you ever turned over an old log in the woods? If you have, you know that many small creatures live in and around these logs. Many of these creatures are arthropods. Over 80 percent of all known animal species are arthropods, a group that includes insects, spiders, scorpions, ticks, mites, centipedes, and millipedes. In the ocean, arthropods include crabs, shrimps, and lobsters. Scientists have identified over 1,170,000 species of arthropods. Many more will probably be discovered over time.

Arthropods provide many ecosystem services to people. These services include pollination, food, decomposition, insect control, and beauty. Can you imagine what would happen if insects didn’t help decompose dead animals and plants? It would be gross! Some arthropods bite or sting if they think people or other animals are trying to hurt them or their nests. For example, bees and scorpions can sting, and sometimes people get sick from some arthropod bites like mosquitoes or tick bites if they are carrying a disease.

The scientists in this study investigated one kind of arthropod. This type of arthropod lives among leaf litter on the forest floor. The scientists wanted to discover what happens to arthropods living among leaf litter after a forest fire moves through the area.


Introduction

Longleaf pine (Pinus palustris) once could be found from southeastern Virginia to eastern Texas (figures 1 and 2). This was an area covering 90 million acres or almost 82 million football fields.

Longleaf pines are not usually killed by fire. Because these pines need open spaces to survive, fire is a good thing for longleaf pines. Purposely set and controlled fires keep other plants and trees small, leaving more space for longleaf pines to grow. Even when longleaf pines are young, they can survive fires (figure 3). When old longleaf trees die and fall, the logs are also able to survive forest fires.

Over many years, much of the longleaf pine forests were cut for lumber. Since longleaf pine was hard to grow in nurseries for replanting and it grows slower than some other pines, longleaf pine was often replaced with those other pines. Also, because wildfires caused so much damage, forest managers tried to stop all fires because they wanted to protect the new forests. Land where longleaf pine grew was also used for other things like farming. These actions reduced the area where longleaf pine forests can still be found to about 5 percent of the area in figure 2a (see figure 2b).

Now, however, many people are concerned about longleaf pine forests. In many areas, these forests are being managed to help them survive and grow. Fire is a necessary part of this process. Forest managers, therefore, set planned fires every few years in longleaf pine forests (figures 4a and 4b). These fires are tightly controlled so that they do not escape from the longleaf pine forest.

One reason for these controlled fires is to remove the leaf litter on the forest floor so that uncontrolled fires or wildfires will be less likely to happen. Remember, however, that the old logs do not readily burn. The scientists in this study were interested in what happens to arthropods after a fire. They developed a hypothesis about the importance of old logs lying on the forest floor to leaf-litter-dwelling arthropods. The scientists thought that after a fire, arthropods living among leaf litter would move to the areas around old logs because they didn’t have other places to hide. They stated their hypothesis as a null hypothesis.

Methods

The scientists studied an area in the Osceola National Forest in Florida (figure 5).

The scientists divided the area into 24 separate areas (figures 6a and 6b). Each of these areas was 0.8 hectare in size.

Figure 6b. This area was burned every other year.

In each of the 24 areas, the scientists placed a longleaf pine log in the center. Each log was three meters long. They placed four pitfall traps around each log. Pitfall traps are cups placed into the ground. An arthropod walking nearby may fall into the trap. The scientists placed a pitfall trap near each end of the log on both sides (figure 7).

Then, the scientists located an area 10 meters away from each log. They placed a solid aluminum fence, three meters long and about 20 cm high (to arthropods that is high) in this area (figure 8).

 

Drift fences in the ground
Figure 8. Drift fences, which are fences placed to direct animals into pitfall traps, were placed 10 meters away from the log.

 

They placed four pitfall traps around each fence, in the same positions as traps were placed around the log. The scientists used the fence because they were concerned that they might catch more arthropods around the logs simply because the logs acted like a fence. The fence would help direct any nearby arthropods into the traps. By using a fence the same length as the logs they could find out if the arthropods liked the logs because they were better places to hide or find food.

 

The scientists used the pitfall traps for 6 months every year. They collected any arthropods caught in the traps. They identified the arthropod species and counted each one. They collected arthropods in the pitfall traps from 1994 to 2000.

 

The scientists compared the number of leaf-litter-dwelling arthropods captured near the log and near the drift fence for each of the four types of areas (see figure 6a).

Findings

The scientists caught more leaf-litter-dwelling arthropods in traps near the drift fences than they did in traps near the logs.
When they compared the sites that had been burned at different frequencies (see figure 6a), they found no difference in the number of arthropods captured. The scientists found no evidence to support the idea that leaf-litter-dwelling arthropods move close to logs after fire burns through an area.

Discssion

The scientists were surprised at their findings. They considered other reasons that fewer arthropods than expected were trapped near logs. One reason may be that drift fences, since they are hard to crawl over, are better at directing arthropods into the traps. Arthropods near logs, in contrast, may dig under or climb over logs, thus finding other routes away from the traps. Another explanation may be that fire, regardless of how often it comes to a longleaf pine forest, does not cause leaf-litter-dwelling arthropods to seek logs as habitat.

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-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.
  • LS2.A-M1
    Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.
  • 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.
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.

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.

    A sample "Thinking About the Environment" section from a recent monograph
  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:

  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 journal 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)
    • Most Crosscutting Concepts (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

    Next Generation Science Standards applications:

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

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.
