  Hummingbirds: Magic in the Air – PBS (2010)

  March 6, 2013 at 5:03 pm / Evolution, Natural history, PBS Nature, Video, Wildlife Documentaries

  Hummingbirds. Today they are strictly found on American continent but there are hummingbird-like fossil specimens from Germany hinting that this group might have been more widespread in its evolutionary past. More than 8000 species of plants have evolved to get their pollination services from hummingbirds. In 2013 a 50 million year old fossil showed the earliest ancestor of hummingbirds. With a heart beating at 600 beats per minute hummingbirds are champions of survival. The PBS documentary explores a rich repertoire […]

  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 […]

  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 […]
