An Investigation of Evolution in Chrysomelid Beetles of the Genus Leptinotarsa, Vol. 5 (Classic Reprint) by William Lawrence Tower PDF Summary

Book Description: Excerpt from An Investigation of Evolution in Chrysomelid Beetles of the Genus Leptinotarsa, Vol. 5 The investigations, the results of which are herein set forth, have been carried out by aid from the Elizabeth Thompson Science Fund, in the collection of the data of distribution and migration of L. decemlineata and in some of the earlier experimental work upon the same species, and by certain grants from the University of Chicago and from the Carnegie Institution of Washington, which have made possible experimental study in the tropics. I desire to express my deep sense of obligation to all these for the aid rendered. The investigations have been conducted in the Museum of Comparative Zoology in Cambridge, in the Biological Laboratory of the Brooklyn Institute of Arts and Science, at Cold Spring Harbor, and in the Hull Zoological Laboratory of the University of Chicago; and to the directors of these institutions and their staffs I am under great obligation for much kindly advice and valuable criticisms. The experimental studies presented in this contribution, with the exception of three small experiments, were brought to an end in July, 1904. Through the carelessness of workmen engaged to attend to the heating plant of the university, on the hottest day of the season steam was turned on in full force in the greenhouse where my experiments were, terminating at once the series of experiments and cultures which had been carried with great labor and expense through several years. These cultures have been started again and are now being continued at Chicago and in the tropics of southern Mexico.
