The Day The Mesozoic Died HHMI – Sean B. Carroll (2012)

March 30, 2016 at 3:09 pm / Evolution, Global Patterns, Video

This is one of the four educational video series by Sean B. Carroll produced for communicating evolution to public with the support of HHMI. Today we know the cause of the disappearance of the dinosaurs at the end of the Cretaceous period. This knowledge was produced by the meticulous coordinated work of many scientists. The Day The Mesozoic Died focuses on how scientists do the detective work using the scientific method. The discovery that an asteroid struck the Earth 66 […]

How Does the Purple Bacteria Photosynthesize? Beckman Institute-UIUC (2015)

March 28, 2016 at 11:03 am / Evolution, Molecular Nature, Video

Imagine a time when our young Earth was spinning much faster and days were only 8 hours! Our sun was much cooler and less bright than today. There was no oxygen in the atmosphere. Those were the conditions when first photosynthetic organisms with purple pigments evolved in liquid environments. In this animation we see one such ancestral form of early anoxic photosynthesis taking place in the purple bacteria Rhodobacter sphaeroides in which oxygen is not produced. Life evolved into oxygen […]

Now everything digital, an overview of the modern camera sensors is useful for naturalists. This lecture by FilmmakerIQ is a part of the Technical Notes series by Nature Documentaries aiming to compile useful technical, theoretical and practical knowledge for documentary filmmakers. The episode illustrates the electronic working principles of […]

The History and Science of Lenses – FilmmakerIQ (2015)

March 24, 2016 at 11:16 pm / Technical Notes, Video

Glass has been a truly transformational material in Human history. Among many other remarkable things glass helped us understand and control properties of light. From photocopying machines to fiber optic cables glass revolutionized our lives. Gutenberg’s printing machine was a turning point with an unintended consequence. Printing created a huge demand for spectacles and glasswork craftsmanship in Europe literally exploded. Craftsmanship that built spectacles lead to building of more specialized optical instruments including microscopes, telescopes and eventually cameras. For all […]

Depth of Field and Lens Equivalents – FilmmakerIQ (2016)

March 24, 2016 at 11:14 pm / Technical Notes, Video

How does one achieve a sharp and clear image? What is depth of field? What is depth of focus? What affects their shallowness? This episode from FilmmakerIQ nicely explains the theory behind using the physics of light. Before starting the lecture you should have some basic understanding of the camera lenses such as the aperture. This is a part of the Technical Notes series of Nature Documentaries aiming to compile useful technical, theoretical and practical knowledge for documentary filmmakers. The […]

The History of Frame Rate for Film – FilmmakerIQ (2015)

March 24, 2016 at 11:11 pm / Technical Notes, Video

This is a great breakdown of seemingly arbitrary and highly variable frame rates we experience today. Until the incorporation of sound which arrived as a superbly egalitarian/standardizing factor into the film, the frame rates were rather floppy. This lecture by FilmmakerIQ is a part of the Technical Notes series by Nature Documentaries aiming to compile useful technical, theoretical and practical knowledge for documentary filmmakers. The compact episode introduces the historical transitions from hand-cranked cinematographic cameras into television and later to […]

The Properties of Camera Lenses – FilmmakerIQ (2015)

March 24, 2016 at 11:08 pm / Technical Notes, Video

The Technical Notes series of Nature Documentaries aims to compile useful technical, theoretical and practical knowledge for documentary filmmakers. In this lecture from the FilmmakerIQ you will be exposed to some basic properties of the camera lenses such as the focal length and the aperture. The episode is also a good segway into sensor technology which also gets covered in more detail in another episode. The episode gives a quick primer on focal length, field of view, diffraction theory and […]

Visitors of Jerusalem Thorn (Paliurus spina-christi)

March 18, 2016 at 1:07 pm / Ecological Documentaries, Natural history, NatureDocumentaries.org, Short Observations, Video

The Jerusalem Thorn (Paliurus spina-christi) is a native evergreen bush of the Mediterranean basin belonging to the Buckthorn family (Rhamnaceae). As you might have already guessed from its scientific name, this is the plant depicted as a torture device (the crown of thorns) on prophet Jesus Christ’s head. The genus Paliurus is quite recognizable by its orbicular-winged fruit. The fossil record for the genus is widespread in the Northern Hemisphere and goes back to the middle Eocene epoch (~34 million […]

Visitors of Starry Rosinweed – Silphium asteriscus (Asteraceae)

March 11, 2016 at 2:00 pm / Ecological Documentaries, Natural history, NatureDocumentaries.org, Short Observations, Video

A brief record of the insect visitors on a starry rosinweed in less than half hour period during August 14th 2010 at the State Botanical Garden in Athens, GA. Visitors/pollinators included long-horned bee (Melissodes bimaculata), Juvenal’s duskywing (Erynnis juvenalis), Carder bee (Anthidium illustre), Fiery skipper (Hylephila phyleus), Scoliid wasp (Scolia nobilitata), another long-horned bee belonging to genus Melissodes and Silvery Checkerspot (Chlosyne nycteis). In this short observation, the last visitor of the flower was a Silvery Checkerspot with rather beat […]

Vertov’s “Man with a Movie Camera” (1929)

March 10, 2016 at 10:45 pm / Technical Notes, Video

Dziga Vertov’s “Man with a Movie Camera” has shown the world the capabilities of the cinematographic camera. The silent movie was advised to be accompanied with a fast-moving musical score. Since its release the film has been rendered with many soundtracks. Man with a Movie Camera took 4 years to film. It documents the daily life of modern Soviet city life, spanning four cities — Kharkiv, Kiev, Moscow and Odessa. The manifesto at the beginning of the film heralds the […]

The Carnivorous Venus Flytrap Plants Can Count – Jennifer Böhm (2016)

February 27, 2016 at 3:09 pm / Evolution, Natural history, Video

Researchers at the University of Würzburg, in Germany have shown for the first time that carnivorous Venus flytrap plants (Dionaea muscipula) have the ability to track time between two stimuli 20 seconds apart precisely. This time keeping ability is a remarkable evolutionary adaptation that minimizes false signals that may lead to unnecessary trap closure. Nature is full of random unexpected events and Venus flytrap survival depends on a reliable trigger mechanism for its trap closure. A sensitive trap closing due […]

Lord Howe Stick Insect (is not extinct!) / Sticky – Jilli Rose (2013)

February 12, 2016 at 9:26 am / Natural history, Video, Wildlife Documentaries

Evolutionarily speaking, extinction is like the massive hidden part of an iceberg. More than 99% of nature’s experiments have failed but the successful 1% that is remaining is stunning us as we continue to learn. Not all extinction is natural however. As we are more and more certain Anthropocene, Human caused extinction rate is becoming much higher than the natural background extinction rate. Scientists are rushing to assess the on going rate of the extinction in different parts of the […]

Paper Wasp Shaves (?) Caterpillar – Ron Goor (2013)

January 21, 2016 at 3:28 pm / Natural history, Short Observations, Video

The behavior of this paper wasp worker was recorded by Ron Goor in C & O Canal in Seneca Maryland, United States. At first glance it looks quite curious since it appears as if the wasp is shearing its prey like a sheep. However when viewed carefully the wasp is simply consuming the caterpillar most probably belonging to Virginian Tiger Moth (Spilosoma virginica) before flying back to its nest. While the worker wasp is literally taking “her cut” from the […]
