    Brown Bears during Salmon Run in Katmai National Park – Live from Alaska

    [Video streams have no sound and will be off air when it’s night time in Alaska] (Ursus arctos) are Caniform (dog-like) mammals. Except the polar bear (Ursus arctos horribilis) who is strictly a carnivore all other brown bears (Grizzly, Kodiak and Siberian brown bear) are omnivores and biologically are the same species. This means they can interbreed when species barriers gets lifted. As Arctic sea ice disappears polar bear habitat shrinks and thus they are forced to move southern latitudes […]

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

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

    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)

    The Diatomist – Matthew Killip (2014)

    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 […]

  • Live from a Sparrowhawk Nest in METU

    Live from a Sparrowhawk Nest in METU

    This is a live broadcast from a Eurasian sparrowhawk (Accipiter nisus) nest in METU Erdemli Institute of Marine Sciences Campus. As birds of prey sparrowhawks an important role for imposing a trophic cascade in ecosystem functioning. Close to 98 percent of their diet consist of other birds. Now you probably may have appreciated the name better. A pair of sparrowhawk are breeding in METU Erdemli campus every year. The nestcam monitoring project aims to understand breeding habits of sparrowhawks better. […]

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

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

    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 […]

  • Keeling’s Curve: The Story of CO2 – Science Bulletins – AMNH

    Keeling’s Curve: The Story of CO2 – Science Bulletins – AMNH

    Keeling’s Curve: The Story of CO2 was produced by Laura Allen for the Science Bulletins of the American Museum of Natural History. Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History. Ice cores drilled from the glaciers, Greenland and the Antarctic have shown that carbon dioxide levels in the atmosphere is tightly linked to the average temperature of the Earth. […]

    The Cuckoo – Artur Homan (2013)

    In the James Bond movie Spectre there’s a reference to the cuckoo bird in two scenes. The evil villain Spectre leers: “I see you! Cuckoo!” when he detects Bond in the classic evil assembly room scene. In the other scene towards the end of the movie Spectre reveals why he considers Bond as a cuckoo. In order to understand the reference we must know the biology of the Common cuckoo bird (Cuculus canorus). The European common cuckoo is a well […]
