Subjects: Earth Sciences, Ecology and Evolutionary Biology, Environmental Sciences, Environmental Studies, Nature and Society Relations, Other Plant Sciences
In this Survey, the Tabor Tree Project identified 130 trees randomly in all 12 zones of the park called Mt. Tabor in Portland, Oregon. The Majority of the Trees at Mt. Tabor Park are conifers, and specifically Douglas Fir who can live longer than 1,000 years. The oldest one in the park is 496 years old, and sprouted sometime around 1520 AD. Through the efforts of Tree Medicine hikes and Citizen [...]

The paleoecology of Rano Kao and the Environmental dynamics on Rapa Nui -the last 15,000 years
Published: 2023-07-31
Subjects: Physical Sciences and Mathematics
Summary Recent Research at Ava Ranga Uka includes the coring of four water sites along an 8km long collapsed lava tube to find out if significant carbon and nitrogen relationships to drought and rainfall fluctuations could be found on the terrestrial landscape. In 2005 we conducted the first paleoecological studies using oxygen isotopes were conducted in Rano Kao and the core KAO3 produced [...]

Cosmic Relationships: Comets, Human Behavior and New Discoveries on Easter Island
Published: 2021-01-22
Subjects: Other Astrophysics and Astronomy, Other Earth Sciences
Humans have recorded celestial events for as long as we have been able to draw and write. Pictographs, petroglyphs and even standing stones mark moments in time on the landscape to remember changing seasons and repeating cycles. Some merge together to form cosmic relationships where great civilization collapse is ushered in by a supernova and stamped onto a rock with a hand print. This historical [...]
