Iriartea deltoidea is a tall canopy palm tree. The only plant material for DNA extraction is the leaf. I used a crossbow (Barrnett RX-150) with fishing reel attachment to shoot a line over the palm fronds. Once the bolt with the fishing line gets down I replaced the line with a much stronger chord to pull down the palm fronds. I used blue micropipette tips to prevent entaglement of the knot. Sizes of the palm fronds can be more than 3 m in length. Here the person in red hat is my field assistant Rigoberto G. Vargas. On a good day we could sample from up to 10 trees. The ecologist`s victory cry "Yu-hu-hu-huuu" has been created by one of my collegues, Ugur Zeydanli from Turkey in 1998.

Short video of the mass breeding event of red eyed tree frogs (Agalychnis callidryas ) from La Selva Biological Field Station, Costa Rica. This is a footage I took during my 6-months field season in 2001.
"The Frog Orgy" is an example of a mass breeding event that
happens few times in a year and lasts less than 24 hours. There is no narration for this one yet:
