Archival Research01:40

Archival Research

16.0K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

Global Climate Change01:50

Global Climate Change

24.4K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Naturalistic Observations

15.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

What is Evolutionary History?02:35

What is Evolutionary History?

36.5K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

The Fossil Record02:56

The Fossil Record

25.2K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Data Collection by Observations01:08

Data Collection by Observations

12.0K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

    Area of Science:

    • Ecology
    • Museum Science
    • Data Science

    Background:

    • Museum specimens are crucial for ecological, evolutionary, and environmental research.
    • The concept of "extended specimens" expands data beyond physical objects.
    • Field notes offer rich ecological observations but are underutilized due to their qualitative nature.

    Purpose of the Study:

    • To develop a method for transforming qualitative field notes into quantitative data.
    • To demonstrate the utility of field notes as a source of ecological data.
    • To enhance ecological research using historical naturalist records.

    Main Methods:

    • Developed a novel approach to convert descriptive ecological notes into statistically analyzable data.
    • Tested the transformation method using simulated and real-world ecological datasets.
    • Validated the retention of reliable quantitative ecological information.

    Main Results:

    • The transformation approach successfully converts field notes into quantitative data.
    • The method retains reliable ecological information across various sample sizes and evolutionary scenarios.
    • Field notes, when processed, provide valuable data for ecological investigations.

    Conclusions:

    • Field notes represent an underutilized data source with significant potential for ecological research.
    • This approach facilitates the study of diverse clades and long-term environmental changes.
    • Unlocking field note data can improve ecological understanding and future change predictions.
