It has been suggested that the variability of the primate vomeronasal organ (VNO) may be greater than previously thought, especially among New World monkeys. It is not clear to what extent VNO variation reflects ontogenetic, functional, or phylogenetic differences among primates. The present study investigated VNO anatomy in an ontogenetic series of two genera of callitrichid primates, in order...

Alcelaphine herpesvirus type 1 (AHV-1) is a causative agent of the fatal lymphoproliferative disease malignant catarrhal fever in deer and cattle. The genomes of the attenuated WC11 isolate and the virulent C500 isolate have been studied. The genome of WC11 comprises a region of unique DNA of approximately 130 kbp, which has a G + C content of 50%, and approximately 30 kbp of additional tandem ...

Our present knowledge ofhow mammalian retinal ganglion-cell receptive fields are organized is based mainly on findings in the cat by Kuffler (1953). These results have since been confirmed and extended (Barlow, FitzHugh & Kuffler, 1957; Hubel, 1960; Wiesel, 1960), but up to now similar studies have not been made in primates. The retina of the monkey is of interest, since in most species, includ...

In vitro binding of a Herpesvirus ateles (HVA)-associated soluble antigen to amphibian erythrocyte nuclei was demonstrated by the acid-fixed nuclear binding technique in combination with anticomplement immunofluorescence. Incubation of concentrated salt-extracted soluble antigens derived from HVA-carrying marmoset lines with methanol/acetic acid-fixed erythrocytes of frogs and salamanders resul...

The occurrence of prehensile tails among only five platyrrhine genera--Cebus, Alouatta, Lagothrix, Ateles, and Brachyteles--might be interpreted as evidence that these are a closely related, possibly monophyletic group. In the absence of behavioral data, it is impossible to test whether all possess equivalent biological roles; such would lend credence to the idea that their tails evolved from a...
