  • A Leafcutter Ant Colony in Barro Colorado Island

    A Leafcutter Ant Colony in Barro Colorado Island

    Filmed on Jan 28th 2017 during the dry season. Smithsonian Tropical Research Institue (STRI) Barro Colorado Island (BCI), Panama. Leafcutter ants are an impressive group with more than 40 different species. All evolved and diversified in the New World at around 12 million years ago. Phylogenetic evidence suggests their evolution could go back as far as 50 million years ago when America separated from Africa. A mature colony can have more than 8 million workers collectively farming a subterranean fungus. […]

  • Great White Shark Pup off the Northern Aegean Coast of Turkey

    Great White Shark Pup off the Northern Aegean Coast of Turkey

    Be prepared to hear a fascinating piece of natural history about the Mediterranean great white sharks (Carcharodon carcharias). Story is fascinating for multiple reasons. First, great whites are one of the most charismatic, vulnerable, cryptic and misunderstood predator fish species. Second, the story takes place in a quite unexpected location. Altınoluk is a town on the northern Aegean coast of Turkey. It is located to the south of Troy on a legendary sea route known as the Argonaut route where […]

  • Exploring the Amazon – Kew Botanic Gardens (2016)

    Exploring the Amazon – Kew Botanic Gardens (2016)

    This short documentary outlines a joint expedition to the Parc Amazonien de Guyane organized by CNRS (Centre National de la Recherche Scientifique), the French Foreign Legion and Kew Botanic Gardens. The area could be rather hostile to scientists where illegal gold mines are in operation in remote and unexpected places along French Guiana-Brazil border. As the prominent tropical biologist Stephen Hubbell described in the foreword of his book Neutral Theory of Biodiversity the state of tropical biology is still resembling […]

  • Cornell University Sapsucker Woods Pond Camera (Live)

    Cornell University Sapsucker Woods Pond Camera (Live)

    This live camera was initially established to monitor nest activities of a heron pair. The nest collapsed during spring 2014. The mating of a female and ‘Dad’ heron in the tree shortly after gave everybody the impression that herons may build a new nest. Unfortunately it looks like the male heron ‘Dad’ who has nested on the pond since 2009 may not have found a suitable mate this year. Volunteer camera operators have been watching the heron activity on the […]

  • Planet Earth – Jungles – BBC (2006)

    Planet Earth – Jungles – BBC (2006)

    Jungles is the 8th episode of the BBC TV series Planet Earth. It makes a rapid tour around the tropical belt and highlights a few key phenomena and spectacular behavior including mating dance of bird of paradise, forest regeneration after a treefall, plant-animal interactions in the forest canopy, fig trees as a keystone species, primate territoriality, forest sounds, mating leaf frogs, water cycle through evapotranspiration, nutrient cycle through decomposition, food webs, parental care in insects, fungal parasitism, gliding calugos, carnivorous […]

  • Plight of the North Atlantic Right Whale – Jeffrey Mittelstadt (2013)

    Plight of the North Atlantic Right Whale – Jeffrey Mittelstadt (2013)

    Directed, edited and produced by Jeffrey Mittelstadt of WildSides the short documentary was made for Whale and Dolphin Conservation. North Atlantic right whales (Eubalaena glacialis) are highly endangered. Less than 500 North Atlantic right whales live in the wild. Close to 350 of them live in the East Coast of North America. The whale continues to be endangered but thanks to conservation measures like the acoustic stations its population more than tripled in a century. Apart from indirect negative Human […]

  • Seed Dispersal by Dung Mimicry – Nature (2015)

    Seed Dispersal by Dung Mimicry – Nature (2015)

    Plant-animal interactions have not always evolved to become mutualistic win-win strategies like birds dispersing seeds of palms while feeding on the fruits. Plants can be rather deceptive. They can hijact sensory vulnerabilities of animals. Secondary metabolites such as nicotine, caffeine, codeine can be rather addictive. Plant chemicals can also be used as deterrent. A sub-Saharan desert plant taily weed (Ochradenus baccatus) detonates a mustard bomb in the mouths of seed predators who dare to chew and destroy its seeds. Plant […]

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

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

    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 […]

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

    Mating Displays of Peacock Spiders – Jürgen Otto (2011)

    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 […]

  • 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 […]

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

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

    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)

    The mosquito-transmitted disease malaria is killing around 600.000 people 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. The 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 […]

  • Preserving Lonesome George – AMNH (2015)

    Preserving Lonesome George – AMNH (2015)

    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 […]

    Archerfish Hunting Using Water Jet – Black Lagoon – Smithsonian Institution (2015)

    The Archerfish posseses one of the most complex feeding behavior among fishes. Complex feeding behaviors involving proto-tool use are common among marine fishes. Scientists have noticed such behavior in many wrasses, in black spotted tuskfish, (Choerodon schoenleinii) from the Great Barrier Reef; in yellowhead wrasses (Halichoeres garnoti) off the coast of Florida; and in a sixbar wrasse (Thalassoma hardwicke) in an aquarium setting. For instance, wrasses crunch sea urchins against corals and use anvils to smash food into more gulpable […]
