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 […]

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

July 27, 2016 at 6:57 pm / Natural history, Video, Wildlife Documentaries

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 […]

Fish Tool Use Documented in the Wild – (2016)

July 27, 2016 at 6:51 pm / Ecological Documentaries, Natural history, Short Observations, Video

The news that a black spotted tuskfish, Choerodon schoenleinii, (Valenciennes, 1839) was observed using a tool made the hearts of ethologists race. Here you can see a few recorded examples of the behavior from different locations and species belonging to the same genus within the wrasse family. As the story goes the behavior was first observed by Scott Gardner in Australia. On November 12th 2006, Mr. Gardner did an 18-m dive in the Keppel region of the southern Great Barrier […]

Anole Lizard Aggression – Neil Losin (2011)

May 31, 2016 at 11:34 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

We humans rarely have punch ups with each other to decide who will mate. However, an anole lizards life is frequently interrupted by brawls. Neil Losin is an evolutionary biologist from UCLA who studies aggressive behavior among anole lizards. Anole lizards not only have punch ups among each other (intraspecific aggression) but they also have such interactions with other species (interspecific aggression). This is when things get even more interesting. In less than 10 minutes this documentary outlines the research […]

Bowerbird’s Grand Performance – Life Story – BBC

May 22, 2016 at 9:20 pm / BBC documentaries, Ecological Documentaries, Evolution, Natural history, Wildlife Documentaries

With its retina punishing feather colors this is a spectacular solo mating dance performed by a male bowerbird advertising his male qualities. The independent dilation and contraction of the pupils is a striking part of the choreography at the beginning of the performance. In Humans male brains perceive dilated eyes as a signal for sexual readiness of females. Seeing the exaggerated form here should make us curious about our “inner reptile” since birds and mammals have evolved from independent reptilian […]

Decoding the Chemical Language of Nature – Jing-Ke Weng | TEDxBeaconStreet (2015)

May 6, 2016 at 9:17 pm / Evolution, Molecular Nature, Natural history

Chemical diversity in nature is bewildering. Repertoire of chemicals in plants is especially rich. A great majority (almost all) of the single-compound drugs have been discovered in plants: salicylic acid (Aspirin), artemisinin (anti-malarial), thebaine (analgesic derived from opium) are just a quick few to spell out. All these chemicals are products of specialized secondary metabolic pathways in plants. Chemical compounds forming specialized metabolites protect plants against various abiotic stresses and mediate an array of interspecies interactions, ranging from seduction of […]

Kars Ardahan Documentary – Alkım Ün (2007)

May 4, 2016 at 5:50 pm / Human Nature, Natural history, Video, Wildlife Documentaries

Director of the KarsArdahan documentary is an emerging Turkish documentarist Alkım Ün. In 2009 he received an award in Boston Turkish Film Festival with this production. Alkım Ün has a degree in biology education and has a particular talent in “reading the landscape” with the eyes of a biologist. Just before the project he had made lengthy observations on wildlife of the region. Kars – Ardahan Plateau is a biologically and geologically distinct region of Turkey. It sits between two […]

Conserving Colombia’s Cotton-Top Tamarin – Federico Pardo (2011)

April 21, 2016 at 11:20 am / Ecological Documentaries, Natural history, Video, Wildlife Documentaries

About the size of a squirrel, the cotton-top tamarin (Saguinus oedipus) is a New World primate. It has a characteristic shock of white hair on it’s head. Males and females do not vary in size (not sexually dimorphic). The cotton-top tamarin was declared endangered in 1973 following the exportation of 20,000-40,000 tamarins to the United States for use in biomedical research. Cotton-top tamarins were found to spontaneously develop colorectal cancer and for this reason served as an ideal model for […]

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

April 14, 2016 at 10:42 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

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 […]

Attenborough and the Giant Dinosaur – BBC (2016)

April 10, 2016 at 10:56 am / BBC documentaries, Evolution, Natural history

On February 19th 2016, a replica of the massive Titanosaurus dinosaur (Patagotitan mayorum) discovered in Argentinian Patagonia was unveiled at the American Museum of Natural History in New York. It is continuing to send strong waves of excitement to all natural history enthusiasts worldwide. Based on accurate dating of the volcanic ash surrounding the fossil we now know that the animal lived 100.6 million years ago during the Cretaceous. It belongs to the Sauropod group and yet is the largest […]

Giant Ichneumon Wasp (Megarhyssa macrurus) Ovipositing

April 3, 2016 at 1:49 pm / Natural history, NatureDocumentaries.org, Short Observations, Video

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 Jerusalem Thorn (Paliurus spina-christi) is a native evergreen bush of the Mediterranean basin belonging to the Buckthorn family (Rhamnaceae). As you might have already guessed from its scientific name, this is the plant depicted as a torture device (the crown of thorns) on prophet Jesus Christ’s head. The genus Paliurus is quite recognizable by its orbicular-winged fruit. The fossil record for the genus is widespread in the Northern Hemisphere and goes back to the middle Eocene epoch (~34 million […]

The Carnivorous Venus Flytrap Plants Can Count – Jennifer Böhm (2016)

February 27, 2016 at 3:09 pm / Evolution, Natural history, Video

Researchers at the University of Würzburg, in Germany have shown for the first time that carnivorous Venus flytrap plants (Dionaea muscipula) have the ability to track time between two stimuli 20 seconds apart precisely. This time keeping ability is a remarkable evolutionary adaptation that minimizes false signals that may lead to unnecessary trap closure. Nature is full of random unexpected events and Venus flytrap survival depends on a reliable trigger mechanism for its trap closure. A sensitive trap closing due […]
