Animal behaviour: Nomads of necessity

Animal models of osteoporosis--necessity and limitations.

There is a great need to further characterise the available animal models for postmenopausal osteoporosis, for the understanding of the pathogenesis of the disease, investigation of new therapies (e.g. selective estrogen receptor modulators (SERMs)) and evaluation of prosthetic devices in osteoporotic bone. Animal models that have been used in the past include non-human primates, dogs, cats, ro...

In this review, I summarize a few key ideas about animal cognition developed in a recent book (Shettleworth 1998, Cognition, Evolution and Behaviour) and briefly review some areas in which interdisciplinary research on animal cognition is curren...

The spatial features of the environment open up a choice of spatial niches and the temporal aspects on the other hand provide opportunities for adopting different temporal niches. Hence, both the spatial and the temporal properties of the environment togeth...
