Interesting Study on Early Separation From Litter


http://press.psprings.co.uk/VR/august/vr4967.pdf

"The results of the present study indicate that early separation of
a puppy from the litter is an experience that may increase the ani-
mal’s chances of showing potentially problematic behaviours as an
adult. Moreover, this effect can be further potentiated by the puppy’s
very first environment. It is well known that experience, genetics
and environment jointly influence most aspects of behaviour, exert-
ing interactive effects (Gottesman and Hanson 2005). In dogs, as in
human beings, the socialisation period is associated with the develop-
ment of social and environmental behaviour patterns, including those
associated with learning," the study reads.

Tale Of Two Tongues



Tongues are important, biologists say. Two recent studies explore tongue design and function--how they are used for lapping by dogs and for nectar retrieval by hummingbirds. Margaret Rubega, of the University of Connecticut, explains how hummingbird tongues, without any muscle, grab liquid. A. W. Crompton and Catherine Musinsky, of Harvard University, and Crompton's dog Matilda, demonstrate how dogs get water in their mouths by flattening the tongue into a plate and how the liquid travels through the mouth. video, stills: Alejandro Rico-Guevara and Margaret A.
