  Leave It to Beavers – PBS (2014)

  May 22, 2017 at 1:14 pm / Ecological Documentaries, Natural history, PBS Nature, Video, Wildlife Documentaries

  There are two species of beavers in the temperate zones of the world. North American (Castor canadensis) and Eurasian (Castor fiber) beavers were almost exterminated to extinction. These rodents are the largest after the tropical capybara that lives in wetlands of the South American tropics. Now bouncing back from extinction beaver populations are recovering under protection. Beavers are being recognized as keystone species by ecologists and conservation biologists. As habitat constructors and brilliant hydro-engineers, beavers can recharge water tables and […]

  Genesis: Final Point – Fernando Gonzalez-I. Sitges (2000)

  May 16, 2017 at 7:23 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

  Galapagos archipelago occupies a special place in our quest to understand nature. It sits right on the junction of the Pacific ocean current where warm and cold water shifts. The nutrient levels reaching the islands by cold Humboldt current show a drastic decline when warm surface waters engulf the archipelago. The Galapagos lies at the southeast trade winds. When the current shifts the rainfall pattern changes drastically. The

  Bald-faced Hornet Worker Collecting Nest Material

  May 9, 2017 at 3:21 pm / Natural history, NatureDocumentaries.org, Short Observations, Video

  A female bald-faced hornet worker (Dolichovespula maculata) was stripping the surface of a wooden fence post to collect nest building material. While stripping with mandibles the cellulosic material gets rolled up under her thorax. She strips a piece as long as her body and then climbs up again to strip another. Two consequtive strips must have been the optimal load size to carry into the nest. Leaf-cutter ants of the neotropics also use their bodies as yard sticks. The motivation […]

  Six Ways to Prepare a Coelacanth – Shelf Life – AMNH (2015)

  April 27, 2017 at 4:11 pm / Evolution, Natural history

  The Coelecanth was thought to be extinct. Its presence as a living species was discovered in 1938 by Marjorie Courtenay-Latimer. It is an immensely important species for evolutionary biology, especially in understanding tetrapod evolution. The story of the discovery of Coelecanth has been covered by many high profile magazines. Since its discovery from fossil remains the Coelecanth has been considered as the closest example for what could be as our last fish ancestor. This means that, it may have been […]

  A Ghost In The Making: Searching for the Rusty-patched Bumble Bee – Neil Losen & Nate Dappen (2016)

  April 22, 2017 at 2:43 pm / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

  Honeybees are fragile animals that have lost most of the traits that provide survival advantage in their wild counterparts. Public attention was particularly grappled when an experiment in the 1950s aiming to regain lost genes by hybridizing domesticated European honeybees with the wild African ones failed miserably. The experiment that started with good intentions lead to invasion of Africanized honeybees from Brazil to north all the way up to Texas. There’s clearly a disproportionately large emphasis on honeybees while neglecting […]

  Acid Test – Natural Resources Defense Council (2009)

  April 8, 2017 at 5:05 pm / Ecological Documentaries, Global Patterns, Video

  Since the beginning of the industrial revolution a quarter of the carbon that has been released into the atmosphere was absorbed by the oceans. As a result the acidity of the oceans has increased by %30. Increasing acidity makes it corrosive dissolving the calcium shells of marine organisms. Among them are planktons, corals and pteropods which form the base of the food web. Carbon dioxide dissolves higher quantities in cold water, therefore first biological signs of acidification is observed closer […]

  Cloud-Aerosol Transport System (CATS) on Board ISS – NASA/SVS (2017)

  March 20, 2017 at 10:54 pm / Ecological Documentaries, Global Patterns, NatureDocumentaries.org, Video

  NASA’s Cloud-Aerosol Transport System is a remote-sensing instrument installed on the International Space Station (ISS) in 2015. Using LIDAR technology it scans a vertical slice of the atmosphere for natural as well as human made aerosols and clouds. The near-real-time data transmitted from the ISS enables CATS team to process it within six hours. One of the natural aerosol sources is volcanoes. In April 2015, the CATS instrument provided a detailed profile of the south Chilean volcano Calbuco when it […]

  The Central Dogma of Biology – Kazufumi Watanabe (2008)

  March 18, 2017 at 1:45 am / Evolution, Molecular Nature, Video

  Riken Omics Center from Japan presents a well-crafted animation that summarizes one of the most important subjects of biology since 1958. The central dogma is our first systematic approach in understanding nature of the information flow and manufacture of structures within a living cell. The viewer must be warned that the structures in this animation are artistic representations and in reality they look quite different from space ships. For example RNA Polymerase II is one of the most well-studied enzymes […]

  The World’s Most Boring TV … and Why It’s Hilariously Addictive – Thomas Hellum – TED Talk (2014)

  March 12, 2017 at 1:23 pm / Technical Notes, Video

  The idea of “slow-TV” was there. For years live cameras have been showing bears hunt fish in rivers, birds nesting and rearing their chicks with viewers in the millions. A Discovery Channel series called “Earth Sunrise” recorded a full hour of realtime sunrise in spectacular locations from around the world. Recording of a total solar eclipse in Brazil and Turkey was quite a memorable event. Slow-TV concept is a paradigm invented by real-time nature observers. The Norwegian television producer Thomas […]

  Origins of Human Cumulative Culture – UCL (2017)

  February 27, 2017 at 10:43 am / Evolution, Human Nature, Video

  Captain James Cook was fascinated by Polynesians’ ability to converse with each other. In Tahiti a high priest named Tupaia got on board and accompanied him along their voyage to Hawaii. Despite the fact that the two islands were separated by more than 2500 miles Tupaia was able to converse perfectly with Hawaiians. In order to maintain a common language these seemingly isolated islands must have been connected by frequent trans-oceanic voyages. Genetical and ecological theory dictates that connectivity is […]

  A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

  February 19, 2017 at 10:26 pm / Global Patterns, Video

  The cryosphere covers parts of the Earth’s surface where water is found in the form of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. Ice and snow exist close to their melting point. Fluctuations in surface temperatures of our planet leads to frequent state changes in water from solid to liquid and back. Using satellite observations scientists monitor such changes in the global and regional climate. The Earth’s cryosphere shrink and expand on a yearly basis. Antarctica The animation […]
