  • European Yellow Jacket Wasp vs. Australian Bull Ant (and other ant-wasp clashes)

    European Yellow Jacket Wasp vs. Australian Bull Ant (and other ant-wasp clashes)

    Ant – Wasp clash is a rather frequent interspecific competitive interaction between the two social insect groups. At first glance wasps may seem to be at an advantage by being aerial. On the other hand, ants can achieve high numbers and squirt formic acid which is a potent neurotoxin for most animals. Wasps and ants both can bite and sting and therefore they are somehow equal rivals. The main footage featured above was filmed in the Kosciuszko National Park of […]

  • Plants are Cool Too! (All Episodes)

    Plants are Cool Too! (All Episodes)

    Welcome to the “Plants are Cool Too!” series supported by the Botanical Society of America (BSA) and hosted by Dr. Chris Martine. Here we will be posting all episodes of the series in reverse chronological order (last-in-first-out) but each program is designed to be viewed independently. Please stay tuned. Plants unfortunately get less attention from wildlife filmmakers. This is most probably due to a narration problem. When we see animals in a film we more or less can interpret what […]

  • The World’s Fastest Runner – Greg Wilson – National Geographic (2012)

    The World’s Fastest Runner – Greg Wilson – National Geographic (2012)

    A well-designed filming set up to capture the motions of running Cheetahs. Since late MIT professor Doc Edgarton’s time highspeed cameras have evolved wonderfully enabling technical capabilities for producing great slow motion films. In this production the filming crew used a Phantom Flex highspeed recording camera. The following talk by the director Greg Wilson gives us the behind-the-scenes view of the project. The entire set up was constructed on the running alley specially designed for exercising the Cheetahs of Cincinnati […]

  • High-speed Filming of Hummingbirds – Harold Eugene “Doc” Edgerton (1936)

    High-speed Filming of Hummingbirds – Harold Eugene “Doc” Edgerton (1936)

    Harold Eugene “Doc” Edgerton (1903 – 1990) was a professor of electrical engineering at MIT. He invented the stroboscopic electric flash to capture events happening at incredible speeds including the explosion of an atomic bomb. Even in today’s standards these images are hard to capture. His uncle was pivotal in beginning of his innovation filled career. He introduced him to the world of cameras. Edgerton invented and developed many different cameras including underwater cameras. One of his cameras was tested […]

  • Albatross Nest Live from Hawaii

    Albatross Nest Live from Hawaii

    If you see a dark screen, bear in mind that it might be night time in Hawaii. Welcome to an Laysan Albatross (Phoebastria immutabilis) nest from the island of Kauai, geologically the oldest island of the Hawaiian archipelago. The webcam is operated by the Bird Lab of Cornell University. The Laysan Albatross gets its name from its Laysan breeding colony in the Northwestern Hawaiian Islands, where it is the second most common seabird. Phoebastria immutabilis breeds at 16 sites mostly […]

  • Cornell University Hawk Camera

    Cornell University Hawk Camera

    2015 breeding season of the famous Cornell University campus hawks Big Red and Ezra has started! Big Red laid her first egg At about 11:38 ET on March 28th. This year Big Red and Ezra moved to their nest to the light pole they used in 2012. There were no longer cameras installed at this nest so some heavy equipment was organized to get up to the nest. Of course, main priority was always not to the disturb the birds […]

  • Rapid Worker Recruitment in Aphaenogaster Ants

    Rapid Worker Recruitment in Aphaenogaster Ants

    In this short observation a single worker drags a yellow jacket wasp (Vespula spp.) until a point close to the nest and then switches to a different task. She leaves to recruit more workers as a scout. Until the first recruits arrive two other workers tend the prey. The location of the prey must be close to the nest because a third worker joins them 55 seconds after the scout leaves. Based on the time stamp of the unedited footage, […]

  • Spider Mom – Alvaro Mendoza (2012)

    Spider Mom – Alvaro Mendoza (2012)

    Egg laying by a female spider filmed by Alvaro Mendoza. Highly choreographed light use makes this short observation particularly striking. Spiders reproduce sexually. Fertilization is internal but the sperm is not inserted into the female’s body by the male’s genitals. Unlike many land-living arthropods, male spiders do not produce ready-made spermatophores (packages of sperm). Males spin small sperm webs on to which they ejaculate and then transfer the sperm to syringe-like structures on the tips of their pedipalps. Image source: […]

  • Giant Ichneumon Wasp (Megarhyssa macrurus) Ovipositing

    Giant Ichneumon Wasp (Megarhyssa macrurus) Ovipositing

    Giant Ichneumon wasp (Megaryssa macrurus, Linneaus 1771) ovipositing. 10th of August 2013, Georgia State Botanical Garden, Athens, GA. 3:47 pm. This observation has been registered in iNaturalist.org with ID# 418639. Oviposition marks the beginning of the life cycle of all insects including parasitoid wasps. Females of Megarryhssa macrurus (Hymenoptera: Ichneumonidae) are specialized to lay their eggs in the burrows of wood eating Pigeon Tremex Horntail (Tremex columba) larvae between June and September. Only one egg is deposited per host larva […]

  • The Antikythera Mechanism: The Two-Thousand-Year-Old Computer – Mike Beckham (2012)

    The Antikythera Mechanism: The Two-Thousand-Year-Old Computer – Mike Beckham (2012)

    Antikythera Mechanism is one of the best demonstrations of human intellect attempting to understand nature systematically. The contraption is most certainly a very complex device. It is an impressively accurate “analog model” of our then earth-centric universe. Science gives us prediction power and Antikythera Mechanism is an excellent example for how astronomical observations can be defined mathematically to reconcile lunar and solar calendars and predict eclipses with hourly accuracy using 27 gear pieces. It uses the Metonic Cyle first implemented […]

    Virtual Reconstruction of the Antikythera Mechanism – Michael Wright & Mogi Vicentini (2009)

    Trying to predict future is one of the characteristics of Human nature which ultimately gave us the scientific method. Antikythera Mechanism is one of the best demonstrations of human intellect attempting to understand nature systematically. The contraption is most certainly a very complex device. It is an impressively accurate “analog model” of our then earth-centric universe. The Antikythera Mechanism was built like a clock. Trains of interlocking gearwheels controlled the movements of a minimum of seven pointers perfectly tracking the […]

  • How Chameleons Change Color? (2015)

    How Chameleons Change Color? (2015)

    Long projectile tongue, independently movable eyes and rapid color change. Chameleons are indeed very interesting animals. Reproductively mature chameleon males rapidly switch on bold threatening colors when confronting another rival male. All this time the the leading hypothesis to explain this color change was that they may be moving pigments around in skin cells. A study by the University of Geneva researchers describes that chameleons change colors by rearranging an ordered array of nanocrystals in the top chromatophore (also known […]

  • 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 […]
