This report summarizes the field work undertaken by a party from the Field Museum of Natural History (Chicago) with the financial support of a National Science Foundation (U.S.A.)
grant awarded to Dr. Robert F. Inger. The field work was begun 23 February 1969 and completed 8 January 1970.
The principal personnel concerned with the field work were: Dr. Robert F. Inger, who
was present for the initial 3 months of the investigation and returned for a few days at the close of the project; Dr. W. Ronald Geyer and Mr. Sukhum Pongsapipatana (ASRCT) who were present
throughout the project; and 5 labours hired locally. In addition, Mrs. Miriam Heyer put in many
volunteer hours aiding in the preservation, sorting, packing of specimens, and aiding in secretarial
work.
Over 5400 individual specimens of 103 different species of amphibians and reptiles were
collected by 3 major sampling techniques. In each case, a body of ecological data was recorded
for each specimen with respect to date, time, and exact place of capture. All specimens have been
shipped to the Field Museum where Dr. Inger is identifying, measuring, and taking the stomach
contents of each individual. A sample of each species collected will be returned to ASRCT.
Almost 500 8 by 8 m. quadrats were sampled from the forest floor of the dry-evergreen
forest; over 700 quadrats were sampled from the deciduous dipterocarp forest floor. Seven
surveyed stream portions (3 on the Sakaerat Experiment Station, 2 south of the Station along the
highway, l at Sarika waterfall, l at Khao Yai) were ampled at nights once each month. The rest of
the specimens were captured during cruising collecting periods either at night or in the day.
Dr. Inger is in the process of analyzing the body of data collected with respect to
diversity patterns, comparative niche sizes, degree of niche overlap, and habitat utilization. The
author will analyze another body of data collected on larval frog populations with respect to
seasonal species, succession patterns, and population dynamics. Mr. Sukhum Pongsapipatana is
in the process of reporting on a collection of reptile eggs made at the site.
