  • A Jaguar and Her Cubs from Belize – Bart Harmsen (2016)

    A Jaguar and Her Cubs from Belize – Bart Harmsen (2016)

    August 30, 2016 at 8:44 pm / Natural history, Short Observations, Video

    In this short observation we see a rare sequence of footage recorded by the researchers working for the conservation program Jaguar Corridor Initiative. These particular observations were captured in Belize but the conservation program covers much of the jaguar range in 14 states including Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, and Venezuela. Jaguar is an elusive top predator of the neotropical forests. Observations of reproductive females and offspring numbers are very valuable in […]

  • Journey Into The Sun – KQED QUEST (2010)

    Journey Into The Sun – KQED QUEST (2010)

    August 22, 2016 at 11:08 pm / Global Patterns, Video

    The Sun is the most influential celestial object for life as we know it. Understanding and predicting its behavior is essential for our existence. Plants are green because our Sun is a red star. However in the early days of life this relationship was quite different. The young Earth was spinning much faster and the days were 8 hours long. The Sun was less bright and cooler. The early photosynthesizing organisms were purple to maximize light harvesting in liquid environment. […]

  • Carolina Anole Lizard Changing Color

    Carolina Anole Lizard Changing Color

    August 18, 2016 at 10:44 pm / Ecological Documentaries, Evolution, Natural history, NatureDocumentaries.org, Short Observations, Video, Wildlife Documentaries

    You can watch the gradual color change in this Carolina anole (Anolis carolinensis) from green to brown over 4 mins.   Summer of 2011 was drier than usual in Athens, GA. Annual rainfall (37.11 inches) was lower than the 1981-2010 average (46.66 inches). The month of July was particularly hot. Average monthly temperature was 81.9 F (above 1895-2012 average of 80.0 F). Reptiles in such conditions have a rather fast metabolism and burn calories fast. This female lizard was a […]

  • Mating Displays of Peacock Spiders – Jürgen Otto (2011)

    Mating Displays of Peacock Spiders – Jürgen Otto (2011)

    August 18, 2016 at 12:11 am / Evolution, Natural history, Short Observations, Video

    Here you see a series of short observations recorded by Jürgen Otto documenting the mating dances of Australian peacock spiders (for full scientific names of the spiders please see a list at the bottom of this post). Peacock spiders are another astonishing example of variation of the same theme in nature: “males display, females choose”. Mating displays have always been an attractive topic. A biological explanation for such behavior is given in a short animated documentary by the Cornell University […]

  • A Mating Aggregation of Bearded Fireworms – Lütfü Tanrıöver (2010)

    A Mating Aggregation of Bearded Fireworms – Lütfü Tanrıöver (2010)

    August 7, 2016 at 12:12 pm / Evolution, Natural history, Short Observations

    A mating aggregation of a Mediterranean polychete worm (Hermodice carunculata). External fertilization is one of the early ancestral ways to produce offspring. Here an underwater explorer based in Fethiye has recorded a spawning aggregation of the Mediterranean polychete worm (Hermodice carunculata). External fertilization is rather costly. Internal fertilization has evolved numerous times as a result of this. One of the most striking example is the Coelecanth with many specimen containing embryos. Egg production requires more resources compared to sperm. Females […]

  • The Life Cycle of a Mosquito – Prelinger Archives (1947)

    The Life Cycle of a Mosquito – Prelinger Archives (1947)

    August 6, 2016 at 4:37 pm / Natural history, Video, Wildlife Documentaries

    The mosquito-transmitted disease malaria is killing around 600.000 people every year world wide alone. The year 2010 was a record peak with 1.2 million deaths. Mosquitos transmit so many diseases that they are arguably the most dangerous animals on Earth. They even act as vectors in transmitting parasites including the Human bot fly. Mosquitoes are a family of small, midge-like flies: the Culicidae. Although a few species are harmless or even useful to humanity, most are a nuisance because they […]

  • Preserving Lonesome George – AMNH (2015)

    Preserving Lonesome George – AMNH (2015)

    August 2, 2016 at 11:00 pm / Evolution, Natural history, Video

    Lonesome George was the last male individual of the Pinta Island tortoise. He sadly passed away in his corral at the Charles Darwin Research Station in Galápagos Islands on the morning of June 24 2012. He died from natural causes. Lonesome George became a worldwide icon of conservation. Efforts to breed him at the Galápagos National Park and Charles Darwin Research Station concluded with no success. Thus he became “a living dead” member of his species doomed for extinction. Lonesome […]
