    Metamorphosis – Tale of a Wetland (Bryan Maltais 2012)

    Nature reveals its ability to heal when amphibians, reptiles, birds and plants repopulate a recently abandoned rock quarry to create a flourishing wetland in Fort Collins, Colorado. However, the scarred earth of this healing quarry causes salamanders to undergo a rare and peculiar shift in their morphology. Time-lapse sequences show seasonal changes of the wetland over one year accompanied by underwater footage of amphibians breeding and undergoing metamorphosis. Everybody is familiar with the metamorphosis of butterflies and moths. The following […]

  • A Tour of a Section of Human Chromosome 11

    A Tour of a Section of Human Chromosome 11

    This video produced by Cold Spring Harbor Laboratories takes us on a tour of about 650,000 nucleotides from the tip of the short arm of human chromosome 11. From a distance we can discern 28 genes, denoted by red and yellow blocks. The red exons carry the DNA code for protein, while the yellow introns are noncoding. Also prominent are more than 500 transposons, or jumping genes, denoted by blue and purple blocks. If we zoom in, we can take […]

  • Ant Tending Treehopper Larvae

    Ant Tending Treehopper Larvae

    May 23rd 2009 in Georgia State Botanical Garden in Athens, GA, USA. The ant (Formica palidefulva) is tending a number of treehopper (Entylia carinata) nymphs. If watched carefully, the honeydew secreted by the instars are visible at [00:22, 00:28, 00:37] seconds into the video. The mother treehopper is still sitting around the midrib of the thistle where she laid her eggs (dark necrotic patch around her). The story got published in the November 2009 issue of the Atlas Magazine under […]

  • Nice Guys Finish First – Richard Dawkins (1987)

    Nice Guys Finish First – Richard Dawkins (1987)

    In this BBC documentary Richard Dawkins explores the evolution of cooperation. The problem has been discussed intensely since Darwin’s time and is still being investigated scientifically. Cooperative species are quite successful but rare. Social insects (ants, wasps, bees and termites) make up only 3 percent of animal diversity yet they may constitute up to 50 percent of the total animal biomass in land habitats. Among 43,678 known species of spiders cooperative behavior evolved in only a few. How could a […]

  • 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. […]

  • A Yellow Throated Warbler Collecting Conifer Leaves for Nest Construction

    A Yellow Throated Warbler Collecting Conifer Leaves for Nest Construction

    In this short observation recorded on May 19th 2012 you can watch a a yellow throated warbler (Setophaga dominica) collecting conifer leaves for nest construction. The way it gathers needle leaves in its beak is quite interesting. Nest construction in birds is not all instinctive and has a consirable learning component. Urban birds can sometimes use rather unconventional materials in their nests. For instance urban birds in Mexico City use fibers of cigarette butts which contain poisonous compounds in making […]

  • Parkta Duran Kelebekler

    Parkta Duran Kelebekler

    15 Haziran 2013 günü Georgia Eyalet Botanik Park’ında dururken gözlemlediğim Apatelodes torrefacta türü güve kelebekler neredeyse tüm Kuzey Amerika’nın doğu yarısında yaygın olarak gözlemlenebilir. Dişiler erkeklerden daha iridir. Bu türün tırtılları dişbudak kiraz vişne akçaağaç ve meşe cinsinden ağaçlar üzerinde beslenirler. Görüntüler iki cinsiyetin tek bir çerçevede görüntülemesi ve yaşam döngüsü içinde olmazsa olmaz niteliğindeki bir davranışı özetlemesi açısından önemli. Örneğin Almanya’da bulunan 47 milyon yıllık iki kaplumbağa taşılı yine benzer bir davranışı belgelemesi nedeniyle büyük ilgi toplamakta.

  • A Nest Building Hummingbird

    A Nest Building Hummingbird

    In this short but condensed observation you can watch a female Anna’s hummingbird (Calypte anna) construct her nest over 10 days between 18-28th January 2010 recorded in Victoria, British Colombia, Canada. She uses fluff feathers of other birds, spider webbings and cotton tissue around seeds of poplar trees as nest material. The size of the finished nest is typically about 5cm across x 4cm high. Unlike most other bird species in all hummingbirds nest construction and parental care is always […]

  • Sponge Bob or Sponge “Poop”

    Sponge Bob or Sponge “Poop”

    It is ironic that biologically diverse habitats are usually rather poor in nutrients. Coral reefs are one of them. Crystal clear waters of the tropical seas is a “clear” indication of nutrient poor environment. Because nutrients in the water column are scarce microscopic plants and animals (planktons) that form the basis of food webs cannot maintain high numbers and the water column remains clear. Dissolved organic carbon is a nutrient that is inedible for most organisms living in a reef. […]

  • A Cannibal Caterpillar?

    A Cannibal Caterpillar?

    On September 22 2012, I encountered this caterpillar eating another fuzzy insect part along the White Trail of the State Botanical Garden of Georgia in Athens, GA. While the munching was going on, a familiar bully of the bushes the ground beetle (Calleida punctata) came in. The beetle harassed and eventually forced the caterpillar away from the leaf. I desperately needed help in explaining the sequence of events happening in this video. Why was the ground beetle so interested in […]

  • Empire of the Desert Ants – BBC (2011)

    Empire of the Desert Ants – BBC (2011)

    BBC Wildlife Division’s Natural World series tells the natural history of the honeypot ant (Myrmecocystus mimicus) in the Arizona desert. This is the first footage to show honeypot ant queens co-operating in the wild. Filmmakers spent 150 days in the deserts of Arizona, US to capture the behavior of the ants. Filming the foundation of a new colony was a considerable challenge because the insects rarely ventured above ground. The team was fortunate enough to witness a mating swarm that […]

  • Nanook of the North – Robert Flaherty (1922)

    Nanook of the North – Robert Flaherty (1922)

    In the days long before the term “documentary” had even been coined this full feature movie did it all. The filmmaker Robert Flaherty (1884-1951) had an early exposure to people of the Arctic. Born in Michigan, he spent quite a bit of time traveling with his father in northern Canada. He developed an ethnographic eye and casually filmed many short sequences of the daily lives of Inuit people. He later decided to put all these clips together to create a […]

  • An Illustrated Introduction to Natural Selection & Sexual Selection – Cornell Lab of Ornithology (2013)

    An Illustrated Introduction to Natural Selection & Sexual Selection – Cornell Lab of Ornithology (2013)

    Cornell Bird Lab produced a series of quite informative teaching materials to provide scientific explanation for how new species have evolved (and are evolving). Evolution is not only a struggle for existence, it is also an effort to pass on genes to next generation. Modern biology has described mechanisms of evolution with fine details and this video effectively tells how natural selection works with three cartoonified traits in an island setting at the first few minutes. In many animals females […]

  • Revealing the Origins of Life – PBS (2011)

    Revealing the Origins of Life – PBS (2011)

    How life began is a very fundamental question. This short documentary is an outstanding primer for scientific explanation of the origin of life. Featuring Nobel prize winner Jack Szostack of Harvard University and John Sutherland of University of Manchester, it explains the chemical evolution leading to the formation of RNA. Scientists all agree that formation of basic building blocks of life is suprisingly very easy. The burning question is how do they react to form complex molecules? RNA world hypothesis […]
