Species
Formation and Adaptive Radiation:

This project studies active speciation and adaptive radiation of the
subterranean
blind mole rat (genus Spalax), which serves as a major evolutionary model.
Investigations include components of pre- and post-mating isolating mechanisms
of speciation; and genetic (proteins and DNA) and phenotypic (morphology,
physiology, behavior) adaptations to life underground.
Particular attention is focused on the loss of sight due to life underground
and compensation by other communication modalities, and to respiratory adaptations
to life in the hypoxic- hypercapnic underground environment. Special projects
include (a) brain structure and function; (b) vocalization; (c) seismic (vibrational)
communication; (d) olfaction communication; (e) photoperiodic perception;
(f) magnetic orientation; (g) genetic basis of behavior, primarily of circadian
rhythms; (h) chromosome, allozyme (enzyme variation), variation, and DNA structure:
(i) evolution of mole rats in Israel, Turkey and Jordan in terms of the origin
of species and their adaptive radiation; (j) structure and evolution of aggression
and pacifism; (k) respiratory adaptations to life underground; and (l) brain
architecture and reorganization.
Mole rats become a promising genetic resource for hypoxic genes and biological
clock genes (see list of publications of Prof. E. Nevo and the recent book:
