Nalini Nadkarni

Nalini Nadkarni (born 1954 in Bethesda, Maryland) is an American ecologist who pioneered the study of Costa Rican rain forest canopies. Using mountain climbing equipment to make her ascent, Nadkarni first took an inventory of the canopy in 1981, followed by two more inventories in 1984.Nadkarni, N.M. 1981.

Career

Nadkarni's interest was first drawn to rain forest ecology due to the contradiction offered by its plant life. There was a great abundance and variety of plant life within the rain forest despite its nutrient poor soil, and her goal was to discover how the plant life was sustained. Her studies within the canopy revealed that the epiphytes, which are non-parasitic plants such as orchids and ferns that live on the branches and trunks of other plants, were trapping organic material beneath their root system. This organic material eventually formed a nutrient rich mat, and trees in the rain forest had developed aerial roots, stemming from their trunks and branches, in order to absorb these nutrients as well. The aerial roots growing into the mats aided the rain forest trees by providing the nourishment that they did not receive from the nutrient poor soil.

Nadkarni and her work in the Costa Rican rain forest were featured in the 1988 PBS series, The Second Voyage of the Mimi, starring a young Ben Affleck. She maintains an interest in public outreach,...
