A Sunfleck Over a Sapling in Barro Colorado Island

January 19, 2018 at 10:25 am / Ecological Documentaries, Natural history, NatureDocumentaries.org, Short Observations, Video

Recorded during the dry season on Jan 26th 2017 at the Smithsonian Tropical Research Institute (STRI) in Barro Colorado Island, Panama. A short duration sunfleck passes over a sapling of Nectandra cissiflora (Lauraceae). Plants growing in the forest understory habitats can be exposed to fast microclimatic changes. Although light is essential for plants, sudden exposure to high light can be detrimental to shade adapted leaves. Sunflecks can be destructive for the photosystem II (PSII), a component of the photosynthetic apparatus […]

Humpback Whales Bubble Fishing – BBC Earth (2015)

January 15, 2018 at 4:38 pm / Ecological Documentaries, Natural history, Video

Cetaceans are the largest animals on our planet. Whales could evolve into such enormous sizes only very recently through the geological time. This became possible due to pulses of nutrients coming from a cycle of glaciations fertilizing the seas for plankton growth. Feeding efficiency is a prerequisite for gigantism to evolve. Truly gigantic animals have always been close to the base of trophic levels and have found a way to maximize feeding on a rich food resource. Sauropod dinosaurs for […]

Charting the Galaxy – from HIPPARCOS to Gaia – ESA

January 15, 2018 at 2:36 pm / Cosmological, Video

Gaia is an astrometry mission that is built as a continuation of the hugely successful HiPParCoS telescope: the High Precision Parallax Collecting Satellite (HiPParCoS). Since 2013, Gaia has been generating the largest, most precise three-dimensional map of our Galaxy by surveying more than a thousand million stars. Gaia monitors every target star about 70 times over a five-year period recording their positions, distances, movements, and changes in brightness. It is expected to discover hundreds of thousands of new celestial objects, […]

Sharing The Secrets – Drew Perlmutter (2015)

January 7, 2018 at 10:11 am / Ecological Documentaries, Video

Caves are powerfull places. Our ancestors were inevitably attracted to these geological formations. Prehistoric cave art that has flourished within the last 50 thousand years is an exciting demonstration of our ancestral relationship with these places. The filmmaker Drew Perlmutter brings the story of cave explorers in “TAG” region to the surface. The geology of the Tennessee, Alabama and Georgia is quite unique that has lead to many cave formations. In fact, the region is home to the highest concentration […]

The Tiniest Fossils – Shelf Life/AMNH (2017)

January 3, 2018 at 9:20 pm / Evolution, Natural history, Video

Foraminiferans or “forams” are extremely fast responding single-celled shelled organisms to climatic changes. They can be extremely small for one could easily mistake foraminifera fossils for flecks of dust. Over thousands and millions of years these tiny specimens adjusted their shapes based on Earth’s climatic fluctuations. Here in this AMNH production scientific assistant Bushra Hussaini, researcher Ellen Thomas, curator Neil Landman, and intern Shaun Mahmood show how they are preserving this invaluable collection. Forams initially were mistaken for another kind […]

What is the Tragedy of the Commons? – Nicholas Amendolare | TED-Ed (2017)

January 1, 2018 at 8:46 pm / Ecological Documentaries, Human Nature, Video

The tragedy of the commons is an economic hypothesis popularized in 1968 by ecologist Garrett Hardin. The concept was examined in a 1987 BBC documentary called “Nice Guys Finish First” by Richard Dawkins with a game theoretical framework. The Tragedy of the Commons predicts ecological degradation due to human conflict of self-interest over the long-term well-being of their community. There are many examples of common resource exploitation such as destruction of cashew trees in Mozambic. However, this theory was heavily […]

The Lava Affair – SKUNK BEAR/NPR (2015)

December 31, 2017 at 10:34 pm / Global Patterns, Video

Continents float on a massive ocean of magma and lava is what we observe when it reaches to the surface. The first technical description of lava flow comes from the Greek geographer Strabo in his book. He describes the Katakekaumene, which means the “burnt country” referring to a region of around 1,800 km2 in western Anatolia. The region harbors a dormant volcanic belt within the town of Kula which has been declared as a UNESCO World Heritage Site. The volcanism […]

The Lichenologist – Matthew Killip (2017)

November 28, 2017 at 7:56 pm / Ecological Documentaries, Evolution, Natural history, Video

This is the second installment from the filmmaker Matthew Killip following the “-omist/ogist” theme. Evolution of cooperation is a curious subject for biologists. The evolution of cooperation is investigated within the framework of game theory and has been encapsulated in a 1987 BBC documentary called “Nice Guys Finish First” by Richard Dawkins. How do organisms belonging to different kingdoms coordinate to live together? What are the rules of symbiosis? Lichens provide this type of study system where algae and fungi […]
