Mud Dauber Wasps Constructing Nests

December 8, 2012 at 9:54 am / NatureDocumentaries.org, Short Observations, Video

Insects never have boring lives. Mud daubers set a great example. These busy wasps build their nest chambers out of mud. Here in two separate videos you can see the two stages of nest construction: [1] Gathering mud by Sceliphron caementarium filmed in Athens, GA, USA. [2] Construction of the nest chambers by Sceliphron destillatorium from Canary Islands. The genus Sceliphron is found in all of the temperate and tropical continental areas of the world and on many islands (some […]

Sinsi Yamyamlar mı? Yoksa Yemeyip Yediren Babalar mı?

October 25, 2012 at 8:54 pm / Video

Canlılığın sürekli değişen sorunlara karşı geliştirdiği evrimsel çözümleri anlayabilmek için alışılmışın dışındaki üreme biçimlerini mercek altına almakta yarar var. Doğada genel olarak dişiler yavru bakımının getirdiği yük nedeniyle seçici roldedir. Erkekler, dişilerin seçici süzgecine takılabilmek için pek çok kılığa bürünür. Bu yazıda üç ayrı balık türünde babaların yavru bakımında üstlendiği evrimsel olarak kararlı davranış biçimlerini inceliyeceğiz. Birbirine evrimsel açıdan yakın akraba olan denizatı (Hippocampus) ve deniz iğnesi (Syngnathus) türlerinde doğada görmeye alışkın olduğumuz eşeysel roller değişmiştir. Deniz iğnelerinde hamileliği erkekler […]

Total Solar Eclipse in Brazil and Turkey – Sunrise Earth – David Conover (2006)

September 19, 2012 at 7:23 pm / Global Patterns, Video

A total solar eclipse recorded in two countries on the same day of March 29th, 2006 by the Sunrise Earth team. The Sunrise Earth series belongs to a genre known as “Experiential TV”, developed by David Conover. The genre was also precursor to the Slow TV genre famously popularized by the Norwegian director Thomas Hellum. In this poetical recording, the eclipse starts in Baia Formosa of Natal, Brazil and moves towards the east to Aspendos of Antalya, Turkey. You can […]

A Biography of Edward O. Wilson – Lord of the Ants (2008)

September 5, 2012 at 11:01 am / Natural history, Video, Wildlife Documentaries

Edward O. Wilson is one of the leading myrmecologists of our time. However, he is best known as a sociobiologist which in his words is “the extension of population biology and evolutionary theory to social organization”. Sociobiology didn’t gain major recognition as a concept until 1975. That year, the publication of his book, Sociobiology: The New Synthesis created a lot of rattle in public space. It quickly drew arrows from prominent scientists of their field including evolutionary biologists. In a […]

Tropical Migratory Freshwater Shrimps

August 30, 2012 at 7:59 pm / Short Observations, Video

These migratory shrimp were filmed in the Peje River, along the border of La Selva Biological Station in April of 2009 by aquatic ecologist Dr. Marcia Snyder. She studied them by measuring their habitat preferences, densities, growth rates and secondary production. She used capture mark recapture technique to estimate their densities and growth rates. Shrimp are largely nocturnal to avoid predators that like to eat them including otters, caiman and fish. During the day, they are often found hiding under […]

After Death: Fossil Carrion Beetles

July 30, 2012 at 3:32 pm / Evolution, Video

Until very recently the oldest known carrion beetle fossils were 50 million years old. The fossil discoveries coming from Daohugou and Jehol rock deposits in Northeastern China extended our knowledge further back till 160 million years ago. During Jurassic period dinosaur abundance had a cascading influence on animal world. When a dinosaur died its carcass became a protein rich multi-generational feeding island. Insects including carrion beetles most certainly exploited this opportunity. Therefore carrion beetle evolution took a new turn leading […]

Two Braconid Wasps Competing to Oviposit

July 22, 2012 at 1:14 pm / Short Observations, Video

On 7th of July 2011, I noticed these two female parasitoid wasps (Braconidae) while walking along the Orange Trail of the State Botanical Garden of Georgia. They were fighting with each other to lay their eggs inside a crack of a log using their long ovipositors. One had a pretty good grip. The other was very grumpy for not having access to the crack. These wasps are said to parasitize a sphingid moth species the Rosy Maple Moth (Dryocampa rubicunda). […]

Atlantik Kasırgaları ve Akdeniz

June 9, 2012 at 7:35 pm / Global Patterns, NatureDocumentaries.org, Video

Ölçümlerin başladığı 1884 yılından beri dünyamızın giderek ısındığı kaydedilmekte. Uydulardan elde edilen yüksek çözünürlüklü ölçümler ısınmanın yakın gelecekteki etkileri konusunda net veriler sunuyor. NASA’nın yörüngeye oturttuğu 16 uydu sayesinde okyanus akıntıları ve yüzey sıcaklıkları gibi küresel ölçekteki olaylar üzerindeki bilgimiz her geçen gün daha da artıyor. Yükselen deniz suyu yüzey sıcaklıkları Atlantik’deki kasırgaların sıklığını ve şiddetini artıran bir etken. Atmosfer bilimciler kasırgaları anlayabilmek için bulutları gerçek değerlere yakın hesaplayabilen bilgisayar modelleri kullanıyorlar. NASA’nın geliştirdiği GEOS-5 bulut modeli bunlardan biri. Akdeniz’deki […]

World Without Sun – Jacques-Yves Cousteau (1964)

May 15, 2012 at 9:50 pm / Human Nature, Video

World Without Sun is perhaps the most progressive documentary in Cousteau’s filmmaking career. Produced in 1964 it captures activities of six crew members living in Continental Shelf Station II at 10m depth for 30 days in Red Sea. The undersea colony was the forerunner of other human habitation experiments such as Biosphere2 or Mars500 and even the International Space Station ISS. It also inspired other film makers like James Cameron. The film must be watched considering the context of its […]

What is A Species? Christina Choate (2011)

May 8, 2012 at 6:37 pm / Evolution, Video

How did diversity of life on our planet form? How does it maintain itself? Species concept is most certainly a very convenient construct for biologists who are trying to understand life. Rightly so, Charles R. Darwin titled his masterpiece as On the Origin of Species for the concept was crucial in developing a theory that is central to biology. The species argument is quite parallel to that of transitional fossils. Both terms are plastic and represent data points along a […]

Nesting Chestnut Mandibled Toucan (Ramphastos swainsonii)

April 9, 2012 at 11:27 pm / Ecological Documentaries, Natural history, Short Observations, Video, Wildlife Documentaries

Filmed and edited by by Jean and Phil Slosberg in 2010 the captured footage reflects a slice of natural history of chestnut-mandibled toucans. Slosbergs were able to record the nest preparation, parental care and nest maintenance phases from their home in Costa Rica. They note that after a successful breeding season the pair tried to nest in the same tree again in 2011 but were not successful because meliponid stingless bees have taken over the cavity. They attempted to clean […]

A Glimpse of Human Ecology Through the Nomadic Life of Netsilik Inuit – Quentin Brown & Asen Balıkçı (1967)

March 28, 2012 at 4:13 pm / Human Nature, Video

The Netsilik Series is very successful in documenting the lives of Netsilik Dr. Asen Balikci of the University of Montréal it became one of the ethnographical masterpieces belonging to a genre called course material for school children. Dr. Balikci has since produced many high quality documentaries. In the beginning, we are reminded of the fact that although it is an accurate depiction of Inuit way of life some parts had to be enacted. It has no narration or subtitles. Hearing […]

Urban (NYC) Hawk Nest – Live 24-Hour Stream

March 16, 2012 at 9:27 am / Video, webcams

Welcome to breeding season 2014! You are watching a pre-recorded livestream of a hawk nest from the 12th-floor window ledge of New York University’s Bobst Library overlooking Washington Square Park. The now famous father hawk Bobby will probably be back for another year, with his new mate, Rosie. We are eagerly waiting for their return from their winter migration. Breeding season 2014 will be the fourth year of live-streaming on a red-tailed hawks nest outside of the New York University […]

When and Why We Lost Hair?

March 9, 2012 at 1:16 pm / Evolution, Human Nature, Nova Documentaries, Video

When and why our ancestors began to wear clothing is a curious story. Clothing may have emerged for insulation of body heat. Similarly it also have provided a means to carry things and improve mobility. Cold snaps engulfed the earth many times. Using ice cores from Antarctica scientists identified 8 glacial cycles within the last 800 thousand years alone. An archaelogical site from Israel provides the earliest evidence of controlled fire by humans spanning the same time period. We know […]
