  48 Cantones: The Mayan Forest – Thomas & Julian Moll-Rocek (2014)

  November 10, 2017 at 8:11 pm / Human Nature, Video

  In their documentary, Thomas & Julian Moll-Rocek explore the Mayan Cosmovision. For Meso-Americans this is a worldview that integrates the structure of space and rhythms of time into a unified whole. In Guatemala’s western mountains, in the state of Totonicapán, a large community forest has prospered for centuries adjacent to densely populated valleys. The Mayan forest cover the hills and the mountain ridge. The management of local resources by the Mayan community provides a counter-argument for the ‘tragedy of the […]

  Development of a Salamander Embryo – Yale University Department of Anatomy (1920s)

  November 10, 2017 at 4:08 pm / Evolution, Molecular Nature, Technical Notes, Video

  Everyone of us started life from one single cell formed by the fusion of an egg and a sperm. That single cell gave rise to every structure in our bodies. How did that happen? Salamanders are known to be able to regenerate limbs while frogs and lizards cannot. How and why? The time lapsed footage of salamander embryos developing from single fertilized eggs forms the basis of our morphological understanding of animal development. The footage recorded by Yale University researchers […]

  Dingo of the Australia – Adam Geiger (2013)

  October 30, 2017 at 12:35 pm / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

  Dingo (Canis lupus dingo) appears in the archaeological record of Australia at 4230 years before present. They ruled the continent as apex predators together with the now extinct Tasmanian tiger within the last few thousand years. Dingoes successfully colonized the continent spreading into diverse habitats including tropical rainforests, temperate Eucalyptus forests, mountainous highlands and grasslands. The only exception is the dry inhospitable central deserts. Dog domestication is the earliest among other animals going back to 40,000 years ago. The Dingo […]

  How mountaintop mining affects life and landscape in West Virginia – PBS (2017)

  September 15, 2017 at 11:15 pm / Ecological Documentaries, Global Patterns, Video

  Coal has been one of the work horses of power generation but its dominance is dwindling. In 2016 U.S. coal energy industry employed around 160,000 workers while solar energy production employed around 370,000. Coal has been a massive contributor to the accumulation of carbon dioxide in the atmosphere leading to mercury pollution with subsequent biomagnification throughout the food chain, ocean acidification and global warming. Some geologists propose that fossil fuel use including coal may be accepted as an indicator for […]

  Hover Fly (Spilomyia longicornis) on Eupatorium altissimum (Asteraceae)

  June 29, 2017 at 10:33 am / Natural history, NatureDocumentaries.org, Short Observations, Video

  Hover Fly (Spilomyia longicornis) visiting Eupatorium altissimum (Asteraceae) filmed in Georgia State Botanical Gardens, Athens, GA, USA on September 16th, 2012. Submitted as a short observation. When we talk about pollination bees immediately occupy our imagination almost as a cerebral Pavlovian reflex. Flies are big component of the insect pollinators yet they rarely get peoples attention. The insect family Syrphidae (aka syrphid flies) has more than more than 6000 species categorized in 200 genera worldwide. They stand out with their […]

  Open-air Processional Column Termites in Bukit Timah Nature Preserve, Singapore (2016)

  June 17, 2017 at 5:05 pm / Natural history, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

  Social insects are a major force in land habitats. A mature leaf-cutter ant colony can consume leaf material equal to a weight of a cow every day. Termites are another insect group (related to cockroaches) evolved independently to achieve sociality. Their effects on ecosystems in terms of material and nutrient cycling can rival those of ants. Higher termites (family Termitidae) feed on a wide variety of plant-based material, including decaying wood, leaf litter, humus, fungi, lichens, dung, and grasses. Non-wood-feeding […]

  The Diatomist – Matthew Killip (2014)

  June 17, 2017 at 12:00 am / Natural history, Video

  Klaus Kemp, is a self-taught master of the Victorian art of diatom arrangement. After his first exposure to the intricate patterns of algae by the German microscopist J.D. Möller (1844 – 1907) he was completely hooked. Diatoms are single celled algae. They are the most common form of phytoplanktons and form the base of the aquatic food chains. They represent the earliest plant lineage long before land plants evolved at about 700 million years ago. Their cell walls are made […]

  Seed Dispersal and Habitat Fragmentation | HHMI BioInteractive – Danny Schmidt (2017)

  June 10, 2017 at 7:06 pm / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

  Forests are under intense pressure. In the tropical forests, between 50-90 % of the canopy trees depend on animals for seed dispersal. Even in temperate forests animals such as deer, moose, boar and even bears disperse seeds. Today due to hunting for bush meat many tropical forests are becoming depleted of their seed dispersers. Here in this HHMI documentary, the researchers Andres Link and Carolina Urbina Malo of Los Andes University in Colombia in Colombia track brown spider monkeys to […]
