“...Pines here almost converge with tropical vegetation”. From the diary of Th.Dobzhansky, 1935 Mexico: Part 2

Аннотация

We represent the last part of the diary of Th.Dobzhansky, an outstanding Russian-American geneticist, evolutionist, and entomologist. These records were made in the summer of 1935, during his trip to Mexico, conducting to study genetic variability in the natural populations of the fruit fly Drosophila pseudoobscura and to determine its native range.
