  • Ants Defending Plants

    Ants Defending Plants

    Plant eaters are called herbivores and they pose a threat for plants. Understandably, nobody would like to get eaten. In order to prevent tissue loss and damage from herbivores plants have evolved defensive adaptations such as hard to digest tissues and poisonous chemicals. Some plants however, have evolved a different solution. Plants can use nectar as drivers of beneficial behaviors such as pollination and protection from herbivores. Nectar is an attractive fluid for many animals. It is a rich calorie […]

    Landscape Evolution Observatory (LEO) – Biosphere 2

    Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better. -Samuel Beckett- Biosphere 2 started as quite an ambitious challenge. It crammed five biomes into 3 acres of sealed facility and tried to create a mesocosm experiment. It was a “ship-in-a-bottle” style miniaturization of ecosystems; a tiny little man-made Hawaii in the Arizona desert (Hawaii is the only place on our planet where all biomes of the world, excepting Arctic Tundra exist). Biomes of the Biosphere 2 were […]

    The Making of the Fittest: Evolving Switches, Evolving Bodies – HHMI – Sean Carrol (2012)

    Evolving Switches, Evolving Bodies is one of the series of educational videos called The Making of the Fittest by Sean Carroll for communicating biological evolution to public with the support of HHMI. Evolution is thought to be acting very slow usually over millions of years. However, it can happen suprisingly quick. In this documentary, we look at a fish that evolved to change its body between two states reversibly multiple times over a few thousands years during the last ice […]

    The Making of the Fittest: Birth and Death of Genes – HHMI – Sean Carrol (2011)

    A fish caught in Antarctic water by the Norvegian expedition in 1927 tells us another fascinating story on evolution of life. Crocodile fish / icefish Birth and Death of Genes is one of the four educational videos Sean Carroll has produced for communicating biological evolution to public with the support of HHMI. These fishes (called Nothothenoids) are unique for they are the only vertebrates in the world that lack the oxygen-binding protein hemoglobin, which gives blood its red color. They […]

  • Appetite for Extinction – Invasive Lionfish of the Bermuda – Robert S. Zuill (2013)

    Appetite for Extinction – Invasive Lionfish of the Bermuda – Robert S. Zuill (2013)

    Lionfish are popular aquarium fish native to the Indo-Pacific region. The lionfish invasion in the western Atlantic began in the mid 1980s off the southern coast of Florida, USA. From Florida, lionfish have spread in all possible directions. By 2000, individuals had been sighted off the coast of North Carolina and Bermuda. First lionfish were reported from the Bahamas in 2004, where they quickly dispersed throughout the archipelago by 2007. The range of lionfish has increased further southward. Lionfish now […]
