Have you been researching the ecology of R. attenuata for a long time?
No, this discovery happened by chance. Some years ago, I began studying the defensive behaviors of various insect species that live in farmland areas. Up until now, I have provided frogs with over 50 insect species to investigate their defenses against frogs. I place a frog and an insect in a plastic case and observe their interaction. Frogs can catch insects with their tongues in the blink of an eye. In order to investigate what kind of defense mechanism the insect used, and to confirm whether it was eaten or managed to escape, I film this interaction and then play it back in slow motion.
Bill would leave intact tax by Forest Resources Institute
Senate changes skirt controversy, but House also has to approve forest products harvest tax rates.
The Oregon Senate has passed a bill that skirts a controversy about the Oregon Forest Research Institute, a quasi-governmental agency that has come under criticism from some lawmakers and drawn scrutiny from news accounts.
The Senate voted 19-10 on Wednesday, June 23, to approve new rates for forest products harvest taxes for various programs. But the bill leaves untouched the maximum rate of $1.12 per thousand board feet that the institute can levy under state law.
It attached the rates to House Bill 2434, relating to revenue, which also makes permanent what had been temporary increases in aviation and jet fuel. Those rates would drop automatically on Jan. 1, 2022, without legislative action.

Cryptomeria japonica, or the Japanese cedar, is highly revered as the national tree of Japan. Locally known as sugi, it covers over 4.5 million hectares of land, accounting for nearly half of Japan s artificial forests. However, it is also notorious for causing hay fever, with a good 26.5% of Japan s population reporting cedar pollen allergies in 2008. Over the past years, pollen allergy caused by this conifer has become a widespread social issue among Japanese residents, with many having to avoid going outdoors during pollen season.
As sterile trees cannot produce and release functional pollen, it is believed that breeding of male-sterile cedar trees could be crucial in reducing the pollen released into the environment. However, their frequency is drastically low, with only two male-sterile trees per 8700 trees in a forest! The rarity of these trees, combined with the large and repetitive genomes of conife
